Abstract: A carpentry measuring tool including two arms pivotally connected at adjoining ends thereof. The two arms are angularly adjustable with respect to one another, and are adapted for determining the angle formed between the interior portions of intersecting horizontal and vertical surfaces of a door or window frame. One of the arms is provided with an extendable slide portion on the end thereof and is adapted for measuring the distance between interior portions of opposed surfaces of the frame. The distal end of the slide portion contains a spring biased heel which may be retracted for removal of the one arm from within the door or window jam. The angular relationship of the two arms and the length of the one arm may be fixed so that these measurements may be transferred to a door or window which is to be hung in a measured door or window frame.
Abstract: A pair of parallel clamping arms hold an adjustable loop, which when applied to the limb, provides a device for puckering the flesh for injections. The parallel clamping arms extend from a pair of bent arms which have a spring attached thereto at the lower portion thereof. The spring serves to push the clamping arms inwardly and to maintain the clamping arms in a normally pressed together condition. The adjustable loop is formed of two cooperating interlocking strips which overlap one another. The loop is adjustable by varying the degree of overlap of the two strips.

Abstract: An insulated container is kept at a temperature slightly above freezing and increments of garbage are fed into the container over an extended period of time. A refrigeration unit is positioned through the top wall of the container so that its evaporator section extends into a perforated baffle within the container.
Abstract: A system is provided for the automatic measurement of red and white blood cell counts and other blood parameters. The system includes hydraulic apparatus for the aspiration of a blood sample and the proper measurement of the parameters thereof. During operation, the system directs an operator at each step of the procedure, allowing only permitted functions to be performed, thereby decreasing the opportunity for operator error. Each blood cell count is performed twice and the answers compared, an indication of instrument malfunction being presented to the operator if the measurements do not agree within a predetermined percentage. The system monitors itself to detect malfunctions which may occur and alerts the operator to the occurrence of a malfunction.

Abstract: A wind proof door knob tag especially for use with exterior doors includes integral flexible detent tabs between the opening through which the door knob passes and the opening which conforms to the outside diameter of door knob shaft. The tabs are cammed outwardly upon downward pull over the knob shaft and snap back into position to hold the tag firmly in place on the door knob despite wind conditions, thereby to prevent being blown away. The tab is made of a polyolefin sheet but could be made of a vinyl sheet which at the thickness utilized, prevents unauthorized opening of locks by insertion of this tag between a door and its associated jamb.
Abstract: A self inverting gauging system for such parameters as capacitively sensed distance or inductively sensed resistivity in which the sensor provides an output inversely varying with the dimension of interest. The gauge typically includes a dual slope integrator responsive to a reference value on the up integration and to the sensor output on the down integration. The interval of the down integration necessary to reset the integrator to the original value varies directly, rather than inversely, with the dimension of interest and is typically provided as the digital output indication of a counter. In the application to resistivity gauging, the up integration reference signal is preferably provided by the output of a thickness gauge such that the ultimate counter display represents element resistivity compensated for thickness.
Abstract: Method and apparatus for isotope separation by selective ionization of a desired isotope in an environment of plural isotopes without corresponding ionization of the other isotopes in the environment. The selective ionization is achieved through a three step excitation of atoms of the desired isotope in response to laser radiations applied to the environment. The transition for each step is selected to be less than one half the ionization potential for the isotopes to avoid two step nonselective ionization.
Abstract: A display device for creating amusing visual effects from the motion of beads of expanded polystyrene or similar materials in a stream of flowing air, accompanied by the audible effects attendant thereto. An air flow is introduced into the bottom of a vertical, transparent column into which has been placed a plurality of beads sufficiently small to be floated by the stream of air. The top and bottom openings of the vertical column are closed by wire screens to contain the beads while allowing air to pass. Colored lights may be employed to illuminate the top and bottom regions of the column.
Abstract: A folding and adjustable tripod for support of a camera or other apparatus and including a central column having slots extending longitudinally of the column in which the upper end of tripod legs are slidable. The legs are of fixed length and each include a slot along a portion of the length thereof within which one end of an arm is slidably adjustable, the other end of the arm being pivotably attached to the lower portion of the column. The legs are extensible by sliding within the column slots while the angular extent of the legs is adjustable by slidable adjustment of the interconnecting arms.
Abstract: A motion picture film which includes a row of sprocket holes along one marginal edge portion and a longitudinally extending area carrying a photo-sensitive layer for photographing a selected scene, or series of scenes in a succession of stationary frames, the film being characterized in that one of its marginal edge portions carries a latent-image numerical identification of each of the successive frames in binary code form adjacent each said frame. A post-production film-making system is also described with means for transferring the binary numbers from the film to a magnetic medium and means for reading and visually displaying in arabic form the numbers on the film and the magnetic medium.
Abstract: A tightening and clamping mechanism for the mandrel collar of a milling or boring spindle. The clamping elements are semi-circular devices with notches in their outer surfaces. By engaging the notches with retainer pins and tightening actuators, the clamping elements may be closed around the mandrel collar thereby securing it to the spindle housing.
Abstract: A needle valve nozzle is employed in a hot melt adhesive gun used to apply thermoplastic adhesive. Actuation of a trigger mechanism supplies pressurized gas to a nozzle chamber which urges the nozzle in an outward direction to an open position, the needle remaining stationary during operation of the nozzle. Deactuation of the trigger mechanism stops the flow of pressurized gas to the chamber and a vent allows the pressurized gas to flow from the chamber, permitting a spring-biasing mechanism to return the nozzle to a closed position. Pressure on the adhesive can also be employed to urge the nozzle to an open position.
Abstract: A patient's hospital gown having two flaps formed thereon, one of which is adapted to overlap the other and to be wrapped around the body of the patient for attachment to the other of the flaps. The flaps of the hospital gown may be secured to one another by any suitable means, such as straps or release fasteners.
Abstract: A peristaltic type pump comprising a pump housing having a circular supporting track for a pump hose and a member mounted rotatably within the pump housing. The member has at two diametrically opposite points, seen in radial direction, dimensions that are substantially equal to the internal radius of the supporting track reduced by the thickness of the pump hose in squeezed shut condition. The rotatable pumping member has a substantially elliptical shape, while the pump hose can be squeezed shut by flattened portions of the pumping member which are substantially perpendicular to the ends of the major axis of said ellipse. The lengths of said portions in tangential direction is substantially equal to the internal diameter of the pump hose, while said flattened portions are adapted for sliding movement over the pump hose when the pumping member is rotating.
Abstract: Flame ionization detector in which the burner consists of electrically conductive material, preferably a noble metal, and is one of the electrodes in the apparatus. The mixture of fuel gas and sample is ignited by passing a current through the burner to incandesce the same. The burner is preferably a hairpin-shaped capillary tube with an aperture in the hairpin bend, disposed in the upper part of the detector with the aperture facing the bottom part of the detector. There is also described a flame trap for preventing propagation of flame into discharge line and facilities connected to it. The detector is designed to meet extreme requirements for dependability and reliability, such as when used in apparatus for monitoring anesthesia in patients.
Abstract: The invention provides a composition for forming an intumescent material which upon heating decomposes into gas and a solid foam residue, comprising: a water-dispersible melamine formaldehyde resin which when cured is hydrophobic; a setting agent which hardens in the presence of water thereby to cause the composition to set; a cross-linking agent for curing the resin, the cross-linking agent being a polyamido compound; an ammonium phosphate; polyvinyl acetate; a solid polyhydroxy compound; and reinforcing fibrous material. To form the intumescent material, the composition is caused to set and the melamine resin is cured. The intumescent material has improved anti-cracking properties.
Abstract: Apparatus to reduce pyrophoricity in deposits collected upon collection plates within a chamber employed for vapor deposition. The apparatus is preferably employed in a chamber utilized for isotopically selective photoexcitation, ionization and separation of metallic uranium vapor. The uranium vapor which collects on all surfaces exposed to it within the chamber is caused to collect in a relatively dense, non-porous body by maintaining a suitably elevated temperature for those surfaces while at the same time keeping the chamber itself cooled. The elevated temperature is achieved by baffles shielding the collection plates from the cooler chamber walls to reduce thermal radiation thereto and/or by applying additional thermal energy to the plates.
