Abstract: PHONOGRAPH RECORD PLAYER                ABSTRACT OF THE DISCLOSURE           In a phonograph record player, an improved control mechanism is provided for effecting lead-in movement of a tone arm from an elevated rest position outside the perimeter of a turntable to a selected set-down position on a record supported by the turntable so as to commence a play operation, and for effecting a return movement of the tone arm to its rest position upon the termination of the play operation.  In such control mechanism, a main lever is made to swing by a cam follower engaging in a cam groove of a control gear to effect the lead-in and return movements upon rotation of the control gear by a drive gear rotated with the turntable.  In order to prevent damage to the control mechanism in the event that there is manual interference with swinging of the tone arm during the lead-in or return movements, a tone arm drive mechanism for swinging the tone arm in response to swinging of the main lever is provided with transmission members which are releasable in response to predetermined resistance to swinging of the tone arm.

Abstract: Abstract of the Disclosure Multiple nozzle arrays are formed from an assembly of at least one pair of plates having intersecting channels for receiving orifice clements and sealant. In the preferred assembly, one plate has a single channel for carrying a plurality of orifice elements and a plurality of deeper, parallel cross-channels for carrying the sealant, and the other plate has a similar set of sealant-carrying cross-channels that connect when the plates are joined.  In another embodiment only one plate is machined with intersecting channels of different depth, the shallow channels for carrying the orifice elements and the deep channels for carrying the sealant, the second plate serving only as a cover.  The joined plates, with inserted orifice elements and sealant, are then mounted vertically (preferred em-bodiment) or at an appropriate angle and exposed to a temperature sufficient to cause the sealant alone to melt and to flow by capillary and gravity action to seal the orifice elements in a void-and-bubble free manner and to seal the plates to form a plate block. After gradual cooling, the plate block is sliced into multiple nozzle wafers, which are then lapped and polished and mounted on a back-up plate for attachment to a source of high pressure fluid.

Abstract: REMOTE STARTING SYSTEM FOR A COMBUSTION ENGINE     ABSTRACT     A system is disclosed for enabling a user to start an engine from a remote location, utilizing a receiver for receiving a command signal from a remote transmitter operated by the user, the receiver generating signals to control operation of the starting system. The system enables the user, from the remote location. to effect selective momentary pumping of fuel into the engine prior to activation of the starting operation, and then to start the engine. The system may include apparatus for main-taining the throttle of the engine substantially open until the engine is started and then closing the throttle to an idling position, with automatic momentary pumping of additional fuel into the engine at predetermined intervals during the running of the engine in accordance with the starting operation. Protective apparatus may be included with the system to prevent activation of the starting operation at any time a manually controlled starting switch has been activated prior to activation of the starting system Additional protective devices may be included to prevent improper activation of the momentary fuel feed apparatus by the user after the engine has been started, and to stop the engine upon the occurrence of any of several predetermined events, including excessively prolonged activation of the starter motor without starting of the engine, opening the door or applying the brake of the vehicle in which the system and engine may be installed, or the idling of the engine for a predetermined period of time under control of a starting system.

Abstract: ELASTIC WHEEL WELL FILLER                 ABSTRACT OF THE DISCLOSURE           A flexible elastic ring having a generally rectangular cross section with radially inner and outer surfaces.  A plurality of rigid members are molded in the ring at circumferentially spaced-apart positions and each of the rigid members extends diagonally from an edge at the radially inner surface to an edge at the radially outer surface of the elastic ring.  The ring is mounted in a wheel well of the tire rim with the tire bead overlapping the edge at the radially outer surface to hold down the ring and the ends of the rigid members in that edge.  The other ends of the rigid members are located in the edge at the radially inner surface of the ring adjacent a radially extending side surface of the ring for resisting deflection of the side surface which abuts a radially extending surface of the wheel well. The rigid members prevent the ring from rotating out of the wheel well in this manner when the ring is subject to centrifugal force during rotation of the wheel on which the rim is mounted.

Abstract: ABSTRACT OF THE DISCLOSURE           A device for measuring several components of force and, in particular, the forces of a flowing medium acting upon an object to be measured.  Known similar measuring de-vices used for making aerodynamic measurements on automobile bodies, turbine blades, and similar objects, utilize linkages, levers, tension wires, etc., by means of which separate force-measuring devices, for each direction of force, are connected to the object to be measured.  However, the use of linkages, levers, wires, etc., not only cause errors in measurement, but also vibrations which, as external factors, have a detri-mental effect upon the measuring operations.  The present invention proposes to provide an improved measuring device which is free from measurement in accuracies and disturbing influences, as well as being economical. The device comprises a holder adapted to support an object to be measured, and to which the object is adapted to pass components of force to be measured.  The holder is arranged in a bearing system allow-ing movement in the directions of the components of force, the holder being held in each of these directions by a force-meas-uring device.

Abstract: SLIMES TREATMENT PROCESS            ABSTRACT OF THE DISCLOSURE:    Slimes from electrolytic copper refinery are first treated by leaching them with dilute sulphuric acid under an oxygen partial pressure of up to 50 psi and an elevated temperature, until copper and tellurium present in the slimes are substan-tially dissolved, and effecting a liquid-solid separation of the leached slurry so produced to separate the leach liquor from the leach slimes.  The leach liquor is then treated with metallic copper to cement the tellurium as copper telluride.  The latter is separated from the remaining solution which is suitable for the production of copper sulphate.  The leach slimes containing mainly selenium, lead, silver, gold and other impurities are dried, mixed with a binder and pelletized and the pellets are then roasted to remove selenium as selenium dioxide.  Finally, the roasted pellets are smelted to remove the remaining impu-rities leaving a doré metal containing essentially silver and gold.

Abstract: A HIGH SPEED IGFET SENSE AMPLIFIER/LATCH                      ABSTRACT       Disclosed is a latching type sense amplifier to be used with a static IGFET, random access memory which pro-vides an improved memory circuit.  The sense amplifier employs a pair of depletion mode devices which serve both as load devices for the latch and as means for coupling a pair of bit lines to the sense amplifier.  Prior to sensing, both the bit lines and the switching nodes of the latch are precharged and balanced.  The selection of a memory cell induces a small differential voltage across the bit lines, causing one of the depletion mode load devices to be more conductive than the other.  When the latch is enabled, regenerative amplification causes the latch to seek one of two stable states as determined by the relative conductivities of the two depletion mode load devices, thereby latching the state of the data stored in the selected memory cell.
