Abstract: A mannequin providing a small scale model of a living or fanciful figure, the mannequin being created from a blank of non-woven, synthetic plastic, flexible sheet material having paper-like qualities. The blank is die-cut to define a predetermined pattern of interconnected sections. Each section is contoured to provide the form of a particular member of the figure and includes locking tabs projecting from one edge thereof and complementary slots adjacent the opposing edge to receive the tabs. Each section is convertible into a locked tubular element by rolling the section and inserting the tabs thereof into the slots. The sizes and shapes of the resultant tubular elements simulate the members of the figure. By means of different pattern designs, blanks may be provided each capable of creating a unique three-dimensional figure formed by interconnected tubular elements whose sizes and shapes are appropriate to the figure implicit in the picture.

Abstract: An intravenous infusion pumping system in which an independent and therefore disposable pump set cooperates with a rotor assembly block to produce a peristaltic action conveying a therapeutic solution drawn from a container into a patient. The pump set, which includes a flow line extending between the container and the patient, has a pump chamber interposed therein constituted by a precisely-dimensioned, flexible tube terminating in inlet and outlet connectors. The tube is looped in a block cavity to conform to an arcuate stator wall therein and is subjected to compression by a pair of diametrically-opposed rollers carried by the rotor, the rollers pressing the tube against the wall to occlude the tube and thereby trap the fluid therein. As the rotor turns, the points of occlusion are advanced to propel the fluid toward the outlet.

Abstract: A golf bag adapted to function as a shoulder carrier for a set of golf clubs or as a locked travel case therefor suitable for air transport. The bag, which is molded of rigid plastic material, has a generally cylindrical form closed at either end, the bag being composed of a semi-cylindrical chest section and a semi-cylindrical lid section hinged thereto. The lid section is divided into a major lid which extends from the bottom end of the bag to an upper level below the top end, and a minor lid which extends from the upper level to the top end whereby when the minor lid is swung open, the heads of the golf clubs whose long handles rest on the bottom of the bag are then accessible for removal. The major and minor lids are provided with raised edge borders which, when the lids are closed, overlie corresponding edges of the chest section. The longitudinal course on the borders of the lids have releasable clamps mounted thereon adapted to engage complementary anchor hooks on the chest section.

Abstract: A telemetering system wherein a transmitting device responsive to an input signal derived from a sensor representing a metered variable, such as temperature or flow rate, is adapted to generate a corresponding direct-current signal. This signal is conveyed over a two-wire line to a receiving station through a terminal resistor across which a voltage signal is developed corresponding to the incoming current signal. The receiving station includes a DC power supply whose output is fed over the same two-wire line to the transmitting device to provide operating power therefor. In order to enhance the power available to the transmitting device, the current signal generated by the transmitting device lies in a 0% to 100% signal range in which the ratio of direct-current I.sub.o at 0% signal to direct-current I.sub.100 at 100% signal is greater than 1/5 or 0.2.

Abstract: A converter for converting a variable data frequency which lies in a low frequency range whose upper limit is about 200 Hz to a corresponding digital value. The converter includes an electronic counter having an enabling input and a count input. Derived from the data frequency is a data signal whose frequency is a given sub-multiple of the data frequency as selected by a digital computer. The data signal is applied to the enabling input to enable the counter for a period equal to the duration of a half cycle of the incoming data signal. Derived from an electronic clock operating at a constant frequency above 10,000 Hz is a clock signal whose pulse repetition rate is a given sub-multiple thereof as selected by the computer. These clock pulses are applied to the count input of the counter whereby the count accumulated therein is determined by the duration of the enabling period.

Abstract: A magnetic flowmeter in which a fluid to be metered is conducted through a ceramic spool coaxially supported within a cylinder casing to define an inner chamber. Mounted within the chamber at opposing positions on a magnet axis perpendicular to the longitudinal flow axis of the spool are a pair of electromagnets to establish an electromagnetic field in the spool whose lines of flux are intercepted by the fluid to induce a voltage therein. Interposed between the electromagnets and the outer surface of the spool and conforming to and secured to this surface are a pair of flexible printed circuit boards which are so printed as to define capacitance metering electrodes at diametrically-opposed positions on the spool on an electrode axis at right angles to the magnet axis and at right angles to the longitudinal flow axis, whereby the voltage induced in the fluid is picked up by these electrodes to produce a signal which depends on the flow rate of the fluid.

Abstract: A four-wheel drive toy vehicle having a spring-wound motor capable of travelling over hills and other obstacles. The vehicle is provided with front and rear traction wheel sets whose axles extend across the chassis which support the body. Each axle has a pinion thereon which engages the front section of a two-section coupling gear that meshes with the input gear of a flat spiral spring motor whose output gear engages the rear section of the coupling gear. The input gear is coupled to the input of the spring through a one-way clutch whereby when the vehicle is grasped by the player and pulled back along the ground, the input gear is caused to turn by both pinions to thereby wind up the spring; and when the vehicle is released, the output gear which is turned by the unwinding spring then acts to drive both pinions to advance the vehicle in the foward direction. One of the pinions is coupled by a gear train to a governor which acts to regulate the speed of wheel rotation.

Abstract: An aerosol dispenser and applicator assembly for cleaning and lubricating the sprocket chain of a chain drive. The dispenser comprises a sealed can filed with a liquid lubricant and a gas propellant. Projecting above the upper end of the can is the hollow stem of a spring-biased valve, such that when the stem is depressed, emitted therefrom is a lubricant mist. The applicator is formed by a headpiece having a pair of parallel jaws cantilevered therefrom and supporting respective brushes in opposed relation to define a twin brush whose bristles are flexible. Formed in the twin brush is an internal channel which snugly accommodates the sprocket chain to be treated when the twin brush is pushed against the chain to cause the opposing bristles to yield and admit the chain into the channel. The headpiece includes a depressible actuator key on whose underside is a hollow socket which receives the stem when the headpiece is seated on the upper end of the can.

Abstract: A candle-powered aroma generator in a lantern format housing a candle holder within a cylindrical container provided with a translucent shell mounted on a base and having a removable cover thereover whose roof has a central well. Below the bottom of the well is the burning wick of a candle supported in the holder, the candle flame heating the bottom which then functions as a miniature hot plate. Received in the well and resting on the hot plate is a replaceable aroma cartridge within whose cavity is a porous pad that partitions the cavity into upper and lower air chambers. The lower chamber is in heat transfer relation to the hot plate and the upper chamber has a vent therein. The pad is impregnated with a volatile liquid fragrance, and the heated air in the lower chamber produces a positive pressure therein which forces the air through the pad to volatilize the fragrance. The resultant vapor is discharged into the atmosphere through the vent.

Abstract: An infrared dehydrator unit for minced fish to produce an edible fish product. The unit is constituted by a gas-fired infrared heater provided with a refractory body having a radiation horn from which infrared rays are projected into the interior of a tank containing a load of minced fish to be dehydrated. The tank is provided with an agitator acting to pick up and expose all pieces of the load to the rays to effect dehydration thereof. The radiation pattern of the horn is such as to confine the projected rays to the exposed pieces of the load and to avoid striking and heating the sides of the tank. In this way, scorching and sticking of the agitated pieces when they make contact with these side walls are prevented. As a consequence, the dehydrated pieces are of substantially uniform quality and waste thereof is obviated.

Abstract: A biofeedback system to train an exerciser while he carries out athletic activity in which his arm or feet members move rhythmically, the system translating this movement into an audible musical rhythm which makes it possible for the exerciser to being his activity into harmony with a musical rhythm conducive to optimal conditions of exercise. The system includes a compact electronic music synthesizer having a settable rhythm section, the output of the system being fed to a headset worn by the exerciser so that the music heard by the exerciser has a beat determined by the setting. The arm or feet members having sensors attached thereto which yield pulses whose rate is determined by the movement of these members, the pulses being applied to the rhythm section to control the beat setting of the music so that it is in synchronism with the movement of the members.

Abstract: An optical isolator that includes a light emitter unit for converting an input electric signal to a corresponding light signal and a light detector unit for converting the light signal to a corresponding output electric signal, both units having a casing of the same diameter and a central port. The emitter unit is optically joined to the detector unit by a coupler formed of concentric layers of transparent dielectric material constituted by a core disposed within a cladding tube of the same length to define a light pipe and a sleeve surrounding the tube and projecting therefrom at either end to define input and output sockets to snugly receive the units with the ports thereof in juxtaposition to the opposite ends of the core. The core and the cladding tube of the light pipe have different indexes of refraction, whereby light from the emitter unit is propagated by multiple internal reflections to the detector unit.

Abstract: A pin switch which when actuated by a swingable door or other movable member breaks an electrical circuit. The switch includes a metal frame mountable on a panel and a hollow metal cylinder placed over a port in the frame and projecting from its rear. Received within the cylinder is the rear section of an insulation rod that extends through an end slot in the cylinder and terminates in a contact. The rear section is spring biased so that its contact normally engages the rear end of the cylinder which functions as the fixed contact of the switch, the switch then being closed. The front section of the rod projects forwardly from the port so that when it is pressed in by the door, the rod is axially displaced to effect disengagement of the contacts to open the switch. The front section of the rod is in a corrugated formation to define a series of equi-spaced annular grooves each marking an increment of rod length.

Abstract: An electromagnetic flowmeter having a frame assembly formed by an octagonal metal frame within which are mounted a pair of electromagnets and a pair of electrode holders. The electromagnets are secured to one set of opposing sides of the frame along a first transverse axis which passes through the geometric center of the frame while the holders are secured to another set of opposing sides along a second tranverse axis which passes through the center at right angles to the first axis. The frame assembly is encapsulated within a generally cylindrical plastic insulating body of polymeric material having a longitudinal bore therein defining a flow conduit whose flow axis passes through the geometric center of the frame and is perpendicular both to the first and second transverse axes whereby when the fluid flows therethrough it intersects the magnetic lines of flux produced by the electromagnets.

Abstract: A device for administering to animals a treatment liquid stored in a container, the device comprising a hollow loop serving as a flow conduit between the container and a flexible nozzle mounted on one side of the loop adapted to direct a jet of the liquid toward the back of the animal's throat. The loop has a geometry close to that of an equilateral triangle, the corners of which adjacent the side which carries the nozzle being rounded whereby the loop may be clamped very firmly on the nose of the animal without inflicting pain.

Abstract: An electromagnetic flowmeter in which the fluid being metered is conducted through a flow tube having a pair of electrodes, the fluid intersecting a magnetic field whereby the resultant voltage induced in the fluid is transferred to the electrodes to provide a signal indicative of flow rate. The magnetic field is created by a pair of electromagnets at diametrically-opposed positions on the flow tube to produce lines of magnetic flux thereacross. These electromagnets are driven by a low-frequency pulsatory wave, each periodic cycle of which is constituted by an excitation pulse of brief duration and high amplitude followed by a relaxation interval of relatively long duration so that the resultant duty cycle is low. Because the average power consumed by the electromagnets is at a very low level, this makes it possible to power the flowmeter from a remote station through a two-wire transmission line which also conveys the signal to the station.

Abstract: An outlet for extracting noxious gases generated in a settling tank containing a pool of wastewater, the outlet including an effluent trough supported at a raised position in the pool against the tank wall. The trough is provided with a side wall parallel to the tank wall and lying somewhat below the surface of the pool, a weir being supported on this side wall and extending upwardly therefrom to permit clarified water from the surface region of the pool to spill over into the trough. Overlying the trough and the weir is a flat walk plate that extends horizontally from the tank to the upper edge of a vertical sidewall which extends downwardly into the pool, the sidewall together with the walk plate acting to confine noxious gases emitted into the region above the trough and the weir to prevent their discharge into the atmosphere. The walk plate includes a hatch cover section providing access to the weir when it becomes necessary to scrub and clean the weir.

Abstract: Control apparatus for a hinged stop sign mounted on the side of a school bus to cause the sign to swing out to an outstretched position when the bus door is opened to load or unload passengers and to return the sign to its retracted position when the door closes. The apparatus is provided with a unidirectional motor operatively coupled to the hinged sign through an eccentric drive by a link arm having associated therewith two normally-closed limit switches, whereby in the course of a motor operating cycle, the stop sign is caused to swing out to its outstretched position, at which point one limit switch opens, and then returns to its retracted position, at which point the other limit switch opens. The limit switches are included in a control circuit which supplies power to the motor.

Abstract: A toy vehicle in the form of a pickup truck on whose rear bed are mounted a pair of miniature dog houses in side-by-side relation, each having a triangular roof hinged to the rear wall of the house. Depending from the front end of each roof is a front wall having an arched opening defining the entry to the dog house which is occupied by a miniature puppy whose head projects through the entry. The puppy is otherwise confined within the doghouse and is removable therefrom only by lifting the roof. To discourage unauthorized removal of a puppy from its doghouse when the toy is on sales display, each roof is provided on its underside with a latching lug having a slot therein aligned with holes in the sidewalls of the dog houses. Insertable into these holes and going through the lugs is a disposable locking pin whose tip is so formed as to frictionally engage the side wall hole in which it is received. Hence to release the roofs and obtain access to the puppies, the pin has to be forcibly pulled out.
