Abstract: A quick chucking die holder device for forging presses comprises an upper and a lower die holder and two adapter plates with dies fastened therein. Centering gibs are provided for centering the adapter plates within the die holders and spring loaded wedges make the chucking connection. The wedges may be controlled by means of hydraulic cylinders, or in a modified form, by the proper ram movement thereby movement of the ram is caused to release, or to clamp, the adapter plates.

Abstract: A system for selectively reversing the deflection sweep to a yoke coil of a television receiver system in which a double pole-double throw (DP-DT) switch reverses the current to the deflection coil, a solenoid relay actuates the DP-DT switch, and switch control and arrangement means for energizing the solenoid relay during times when power is not applied to the television receiver system. Also the system provides for a four or more sequential position switch in which intermediate portions of the switch perform as a break-before-make (BBM) stage and the outer portions of the switch positions perform as make-before-break (MBB) stages and the switch comprises a DP-DT and a four position switch operable mechanically in tandem.

Abstract: An improved vegetable and flower snip apparatus for cutting the vegetable okra and thorny type flowers which includes a scissor-type snip having a mating set of nose elements at the terminal end thereof from the handle portion so that there are blade cutting elements and which provide for holding the stem in place while being snipped or sheared.

Abstract: A rotary member is provided that includes a housing having a pair of rotors mounted therein, and wherein there is provided a shaft having a channel or passageway therein that selectively communicates with the chambers in which the rotors turn. The rotary machine is constructed and operates without the use of a crank shaft, cam shaft, and wherein the machine is air cooled.

Abstract: A scanning radiometer having a series of laminations forming a tightly bonded sandwich structure each being electrically insulated from adjacent ones thereof, said series including a thermometric or thermo responsive material, a heat pump functioning material, a heat sink functioning material, and an insulator functioning material, and in which the thermo responsive material is formed of a set of matrix of thin metal alternately with absorptive or blackened portions, each forming opposite arms of a Wheatstone bridge.The use of the term "thermoelectric or thermoresponsive material" designates a metallic or other electric resistor whose resistance is temperature sensitive and when measured, is an indicator of its temperature. "Heat pump functioning material" is a thermoelectric device that tranfers or "pumps" heat from one of its two surfaces to the other when an electric current is supplied to its terminals.

Abstract: A floating liquid-storage tank has side walls of double-hull construction for storing a liquid lighter in specific gravity than water. The double-hull side walls consist of inner and outer hull sections and have watertight partition plates for dividing the hollows of the side walls into upper and lower ballast tanks. The outer hull sections of the upper ballast tanks are built to be resistant to the external water pressure and those of the lower ballast tanks are non-pressure-resistant. Holes through which the water outside can enter the lower ballast tanks are made in the outer hull sections of the lower ballast tanks. The partition plates are horizontally located at or slightly below the level of the intersection of the liquid-pressure distribution line and the external-water-pressure distribution line in the direction of depth of the storage tank in the full loaded condition.

Abstract: A lightweight magnetic stirrer apparatus which may be positioned for rotation in a fluid containing vessel, having a magnetic rotor assembly including a generally vertical center hub on which is mounted a generally horizontal magnetic impeller. The rotor assembly is rotatably mounted in a positioning cage which generally positions the rotor assembly within the vessel and prevents it from contacting the walls of the vessel to allow the rotor assembly hub to rotate free relative to the vessel in the cage under the influence of an exterior magnetic drive. The magnetic stirrer apparatus is also provided with a cage in which the legs are totally removeable so as to make it any size for different beakers. Furthermore, the magnet may be removed completely from the cage so that it may be dropped into the neck of a bottle and the magnet per se used by itself. High lubricity bearing surfaces of the hub and cage reduce frictional forces and allow rotation of the impeller at very low speeds.

Abstract: A system for determining the time of ovulation in females including a probe which measures the body temperature and a probe which measures body potential of a female subject, an electronic amplification circuit and an indicating device which is capable of measuring small changes in temperature and body potential of the subject thereby providing a portable and convenient device for determining time of ovulation.

Abstract: The cage structure comprises a cage having an opening in its upper side provided with a closing device. The latter only allows the passage of a feeding device which is movable along a guide device extending down from a float to inside the cage. A cable attached to the feeding device drives the feeding device along the guide device from the inside of the cage up to the float.

Abstract: Apparatus for protecting low voltage lines of a telephone system and including a jack block which may be mounted on a circuit breaker means having separable contact blades and such jack block has protecting elements including a plug with a plurality of contact studs that may be selectively inserted between the contact blades of the circuit breaker means.

Abstract: A holder for photographs is provided that is especially suitable for use in holding photographs or pictures of the type that are instantly developed. The holder in one form of the invention consists of a sheet of cardboard or other relatively heavy stock that is folded in such a way so as to provide the completed article, and wherein slots are provided in portions of the sheet for receiving edge portions of photographs.

Abstract: A dressing-undressing apparatus helps a nurse to dress and undress a patient or disabled person lying on the bed, by selectively lowering one of mattress elements constituting the bed in response to the movement of one arm of the nurse.

Abstract: Apparatus for reducing the possibility of wrinkling arising during the feed of multi-layer strip material along a feed path including a change of direction, the apparatus including a rotatable paddle-like paper guide having blades which successively engage the inner layer of the strip material in such manner that any excess material which would contribute to the formation of the wrinkles is accommodated in the space defined between adjacent blades.

Abstract: A new, improved, and inexpensive method and mixture of cements for the manufacture of imitation stone used for the purpose of decorating the object or surface upon which it is applied for giving it the appearance of being made of real stone.

Abstract: A compact automobile is provided that includes a chassis wherein the chassis consists of essentially two parts and suitable wheel axles and wherein there is also provided a cradle and shock absorbers and a frame.

Abstract: A method of making flexible radially compressible tubular electrical connectors involving producing a hollow elastomeric core in a tube of precise dimensions, and then removing circumferential strips of the tube to leave separated conductive rings and strips which provide the electrical connector elements of the connector.
