Abstract: A child's exercise toy includes a beam member receiving first and second support legs. The first support leg has two child foot supports associated therewith. A seat is slidably mounted along the beam member and an exercise bar is pivotally mounted with respect to the beam member. A digital display counter counts the number of strokes of the exercise bar. Each stroke is signalled at both ends by a pleasing electronic tone.

Abstract: A differential pressure flow sensor to measure the differential pressure in fluid flow in a pipe including an elongated pressure tube designed as an elongated hollow tube which is provided at its leading edge with at least one dynamic-pressure aperture and a sensor for the static pressure with at least one sensor aperture formed in the rear edge thereof. The sensor aperture being located in the wake of a body, either a separate body or a part of the hollow elongated tube, with front surfaces swept back from a forward tip and which are provided with detachment edges for the lateral detachment of the incident fluid flow without there being subsequent reattachment. In order to obtain the best test results from this differential pressure flow sensor, arcuate recesses are formed in the front surfaces at a distance from the outer limits for forming detachment edges for deflecting fluid from the planes of the front surfaces.

Abstract: A shoe making machine is disclosed. It comprises a base; a slide table movably mounted on the base; a supporting member fixedly mounted on the slide table and having a clamping device for clamping the heel portion of a shoe body; a pair of guide shafts bridged in parallel each other above the slide table; a tiptoe portion carrying member having the tiptoe accommodating member mounted on its top and a pair of guide members connected to its lower end; locking device for locking and unlocking the tiptoe portion carrying member relative to the slide table, a processing tool table for processing the under-surface of the shoe body and having a constant original position to return slightly away from the tiptoe portion in the set state; and a device for controlling the movement of the tool table in the back and forth direction and up and down direction and of the slide table carrying the shoe body in the right and left direction.

Abstract: A rotary mechanism for robot arms and the like includes a base and a shaft rotatably connected to the base and extending therefrom. A first sprocket is carried by the shaft and a second sprocket is rotatably connected to the base in alignment with the first sprocket. A chain is operatively carried by and extends between the first and second sprockets so that movement of the chain causes cooperative rotation of the sprockets and thereby of the shaft. A cylinder and piston assembly has a first end connected to the base and a second longitudinally movable end engaged with the chain intermediate the first and second sprockets so that longitudinal movement of the second end causes associated movement of the chain and thereby rotation of the shaft. A manipulator is carried by the shaft and is pivotally disposed at one end thereof. A table is carried by the shaft and is disposed intermediate the one end and the first sprocket.

Abstract: An emergency descent device includes a fluid-filled chamber with telescopic vanes of variable vane surface for self-adjusting the retarding force of the fluid, and an annular friction member in the chamber for simultaneous rotation with the vane members when the centrifugal force of the vane members is increased and the vane members extend radially outward to reach and engage with the annular friction member.

Abstract: A ceiling fan mounting assembly includes a readily installed specially shaped hanger bracket which provides direct high load and torque resistant support for the ceiling fan assembly, as well as providing support for the electrical junction box.

Abstract: An apparatus for accurately positioning the support member which is carried by a movable member movable along a trackway or the like comprising a fixed cam having an arcuate surface, at least one cam follower engagable with said cam and means for sensing the position of the cam follower relative to the cam so that when the cam follower has reached a predetermined position along the cam the support member is accurately positioned. A sensing means is disclosed including a cam follower shaft attached to the cam follower. An analog shaft angle resolver is rotatably connected to the cam follower shaft so as to measure the angular rotation of the cam follower shaft and produce a voltage corresponding to the angular rotational position of the cam follower shaft. The analog voltage signal is then converted into a digital signal and fed into a digital display which displays a number proportional to the distance the support member is from a predetermined position.

Abstract: The present invention pertains to a carton and a blank and a method for forming the carton for packaging ice cream or the like. The carton blank comprises front, bottom, rear and cover panels. A closure flap is hingedly connected to a top edge of the cover panel that opposes the rear panel. An end flap extends from each end edge of the cover panel, rear panel, bottom panel and front panel. A single tear strip is formed in the closure flap. Also, a single tear strip is formed in the end flap extending from the front panel. Upon removal of the tear strips, the carton can completely unfold and the contents therein can be readily accessed in brick form from all sides.

Abstract: A system for transmitting and accessing data through a standard telephone system. The system including activating a key or sequence of keys wherein each key represents a plurality of letters. Signals produced by activating the keys are compared to a data base having indexed entries of words or names. In this way, words can be input into the system using only 8 unique keys.

Abstract: A steel reinforcing element for vulcanized rubber articles having a thermodiffused alloy coating consisting of from about 59.3% to about 70.7% copper, from about 0.2% to 10.4% manganese and with the balance being zinc.

Abstract: An apparatus and method for the electronic decomposition of water into its component free radical parts and free electrons. In a cell containing an aqueous fluid, an electromotive force is applied to a positive charge storage core, insulated with semi-conductive material, and a conducting cathodic connector having a limited electrolysis bridge therebetween thereby inducing the formation of an aqueous condenser, the anodic section of which consists of the positive charge storage core insulated with the semi-conductive material. The formed aqueous condenser is subjected to overpotentials at which the dielectric breakdown of water occurs. The free radicals produced by such dielectric decomposition serve to treat most dissolved, suspended or precipitous substances in solution by oxidation/reduction reactions.

Abstract: Binding equipment is disclosed which binds loose sheets in covers which have thermoplastic adhesive at their backs to bind the sheets when such adhesive is heated. The equipment has two mutually spaced and parallel support walls to support the loose sheets within the covers. One of the walls is fixed and the other is movable within the frame supporting the walls. A support for the back of the cover is provided underneath the movable wall. This support is provided with a heater to activate the thermoplastic adhesive. The carriage mounting the movable wall moves along a displacement plane which slants upwards towards the fixed support wall.

Abstract: A one-piece collapsible stand, especially for a book, made of suitable material, like corrugated cardboard or polypropylene, by stamping or molding. In its collapsed configuration, all components of the stand are coplanar. The stand comprises a frame-like bottom plate, to which a center leg and two side legs are connected by integral hinges. Complementary latch notches in the side of engaging legs adjacent their free ends interlock to fix the structure in its erected, operative configuration.

Abstract: Sliding wax such as ski wax is made from gallium or molybdenum disulfide. The wax having a low melting point can be applied to sliding apparatuses readily at sites where they are used, and the wax is advantageously applicable to any snow conditions.

Abstract: In an apparatus for synthesizing polynucleotide including a plurality of reactors, bottles charged with reagents and solvents, and change valve means for switching passages between respective bottles and the reactors, the improvement comprises mode selector means between a pressure source and the reactors for switching liquid supply or discharge operation and distributor means for closing or opening passages connected with the reactors to selectively operate the reactors.
