Filed: 1922-09-14
Abstract: 186,604. Cummins, C. L. Sept. 27,1921, [Convention date]. Regulating. - Fuel from the chamber 29 is injected into the combustion chamber on the opening of the valve 45 by the products of a small explosion which takes place as the hot compressed air from the combustion chamber enters the chamber 29 and mixes with the fuel therein. The valve 45 is lifted by the cam 54 through the push-rod 52 and lever 50, and the timing of the opening of the valve may be varied by governor or hand controlled axial movement of the spiral cam 54. Fuel supplied by air pressure from the tank 22 enters the chamber 29 through a valve situated behind the injection valve 45 and independently actuated by the cam 41 through a push-rod (not shown) and the lever 34, which is mounted on an eccentric 35 rotatable by hand or by the governor to control the opening of the valve, and hence the amount of fuel admitted to the chamber 29.

Abstract: 792,418. Semiconductor limiting and transistor generating circuits. WESTERN ELECTRIC CO., Inc. Sept. 6, 1955 [Sept. 17, 1954], No. 25528/55. Class 40 (6). In a limiting circuit a P-N junction diode 12 is connected in series with a capacitor 13 across the output terminals of a signal source 11 to provide symmetrical limitation of both positive and negative waves. The diode is of the type having a constant voltage region in its reverse characteristic (Fig. 2, not shown). When the signal is first applied positive-going half-cycles are suppressed by forward conduction in the diode while negative half-cycles are only suppressed when they exceed the constant voltage in the reverse direction. A positive potential builds up on capacitor 13 with an increasing portion of the positive half-cycle being. passed without suppression. In the final state the voltage on capacitor 13 equals half that of the voltage on the reverse characteristic so that equal limitation of the positive and negative half-cycles occurs. As applied to a transistor oscillator 15, Fig. 3, the output from the collector-emitter circuit is limited by the circuit 12, 13 and applied to potential divider 24, 25. Feed back to the base-emitter circuit is accomplished over crystal 27 and phase-inverting transformer 16. Harmonics are suppressed by circuit 22, 23 tuned to the fundamental frequency and the level of the output is adjusted by varying the tap on the resistor 29 to provide a varying amount of negative feedback in the amplifier 28. In a modification, Fig. 4 (not shown), a separate potential divider is used to feed the crystal 27 so that the biasing arrangement of the amplifier 28 may be independent of the feedback. Specification 792,419 is referred to.
