Abstract: ABSTRACT OF THE INVENTION        A threshold device (10,54,82) is provided which passes very little current when the voltage applied across it is below its threshold voltage and which can pass a large amount of current when the voltage applied across it exceeds that threshold.  The threshold device comprises a common body (12,62) of deposited amorphous semiconductor material and two separate electrical contacts (18,19), each having a junction forming portion (20,21; 60,64; 52,65) in contact with the common body.  The junction forming portions each form a junction (22,24) having a depletion region (26,28) in the semiconductor material of the common body.  As a result, when a voltage is applied between the two contacts, one of the function is forward biased and the other is reverse biased.          Both the spacing between the junctions and the electrical properties of the common body and the junctions are such that when the threshold voltage is applied between the contacts, the depletion region of the reverse biased junction extends all the way to the depletion region of the forward biased junction, greatly increasing the conductivity between said two contacts.  The threshold voltage at which such a punch-through of the depletion regions occurs is less than the voltage required to cause avalanche breakdown across the reverse biased junction.  Among other things, such threshold devices are used as isolation devices (54,82,92,94,102,104) for the individual pixels (42) of a light influencing display (40).

Abstract: ABSTRACT           DEMODULATING AN ANGLE-MODULATED SIGNAL A zero-IF receiver for an FM signal comprises quadrature-mixers (2,3) to which the input signal is applied and which mix the received carrier down to zero frequency. The signals appearing at the mixer outputs (11,12) are fed to a differentiate, multiply and subtract demodulator (22,23,25,27,31) via capacitors (17,19) which block the d.c. components of the signals, thereby preventing amplifier saturation effects, etc This d.c.-blocking would, unless steps were taken to prevent it, result in distortion of the output signal appearing at an output terminal (32). This distortion is prevented by providing an amplitude divider (33) in the output signal path. The signal fed to the divider control input (48) is derived from the output signals of the blocking capacitors by squaring them by means of multipliers (37,40), adding the results together in an adder (43) and applying the adder output signal to the control input (48) both directly and via a low-pass filter (46) the cut-off frequency of which is equal to that of the high-pass filters (15,16) of which the blocking capacitors effectively form part.

Abstract: ABSTRACT OF THE DISCLOSURE           A sprue gated injection molding system having nozzles with a removable hollow gate insert received in a seat in the forward end of each nozzle to form the gate.          Each gage insert has a forward portion with a tapered outer surface which abuts against a matching tapered surface of an opening through to mold to the cavity.  The forward portion of the gate insert is resilient which ensures extremely good contact between them under bearing pressure due to thermal expansion of the nozzle. Thus optimum uniform heat transfer is provided between the gate insert and the cooled mold.  The gate insert has a circumferential removal flange to facilitate it being pryed out of the seat if replacement is required.  In an alternate embodiment an elongated torpedo is seated centrally in the melt bore of each nozzle.  The torpedo has an outer retaining ring and a number of radially extending tapered fins which form melt flow channels between them.  The torpedo is mounted with the retaining ring secured in the seat in the forward end of the nozzle by the gate insert and a pointed tip formed by the fins extending to provide additional heat in or adjacent the gate.  The torpedo has pointed tips at opposite ends and is reversible for different dimensioned applications.

Abstract: A hydraulic system includes a selective control valve and a cam member movable to selected positions for controlling a hydraulic cylinder powered by a pump. A follower is urged to a locking relationship with the cam by a hydromechanical mechanism to releasably hold the control valve in the selected positions. The hydromechanical mechanism includes a bore exposed to sump pressure and to pressure upstream and downstream from a metering valve in a passage interconnecting the pump and the control valve. A hollow apertured sleeve is movably mounted in the bore. An apertured piston is slidably received by the sleeve. A rod, engageable with the follower, extends through the piston and sleeve apertures. A first spring interconnects the rod and the piston and a second spring interconnects the piston and the sleeve. The sleeve moves to a preload position in response to a no-flow differential pressure between the sump and the passage to urge the follower via the rod towards its locking position. The piston moves in response to fluid flow through the passage to bias the follower toward its locking position. The piston and the rod move to automatically allow the follower to release from the cam when the function of the hydraulic cylinder is completed. Also, the sleeve and rod move to automatically allow the follower to release from the cam when system pressure in the passage is lost.

Abstract: A piston of a gas engine is reciprocatingly guided in a cylinder. A gas inlet valve whose valve closure component consists of a ball is situated in the cylinder head. The ball is pushed open in the top dead-center position of the piston by a protrusion formed on the upper portion of the piston in order to admit propellant gas into an expansion chamber formed by the cylinder. The gas engine must be set into operation by turning a crankshaft. If the piston accidentally lies near top dead-center when starting, the piston must be moved against full gas pressure. In order to alleviate starting, a shut-off device is provided which has a start position and an operational position. The shut-off device connects the inlet side of the gas inlet valve with an air conduit opening into ambient air and obturates a pressurized gas container in the start position. The shut-off device obturates the air conduit and clears a gas supply conduit leading from the pressurized gas container to the inlet side of the gas inlet valve in the operational position. With the help of this shut-off device, it is possible to start even gas motors equipped with gear-reduction transmissions.
