Title: Improvements in and relating to electric, pulse-signalling systems
IPC: H03K9/00
Filed: 1947-04-30
Abstract: 652,366. Pulse modulation multiplex pulse signalling ;. pulse shaping circuits. GENERAL ELECTRIC CO., Ltd., and LEVY, M. M. April 30, 1947, No. 11613. [Classes 40 (v) and 40 (vi)] Interference, in a receiver for a modulated pulse train, is reduced by generating a second pulse train of substantially the same waveform as the first but reversed in sign, and combining the two trains with a time displacement between them. Considering one pulse P of a time-modulated train, it is raised together with the base line, to a level p<SP>1</SP> by the interference voltage. It may, alternatively, be lowered, Fig. 2 (not shown). A corresponding inverted pulse D<SP>1</SP>, delayed by a time t, is produced by the reflection of pulse P<SP>1</SP> in a delay network, Fig. 4 (not shown), or by passing pulse p<SP>1</SP> through a matched delay network to a further amplifying valve which effects the phase reversal, Fig. 5 (not shown). On adding pulses p<SP>1</SP>, D<SP>1</SP> the wave (c) is produced, and the voltages due to interference (of a period long compared with the duration of the pulses) cancel. Demodulation is effected by clipping between L<SP>1</SP>, L<SP>2</SP> and selecting the steepened trailing edge of the pulse. The delay time t may vary from half the pulse width to several times the pulse width Fig. 3 (not shown). The factors governing the choice of this value are discussed. In a multi-channel system, cross talk between channels may be reduced by these means. A pulse with two steepened edges can be produced by combining with the signal pulse two inverted pulses, one suitably advanced, the other delayed. Both steepened edges may then be used for demodulation. The invention is also applicable to width modulated pulses, Fig. 6 (not shown). Specifications 641,982 and 652,353 are referred to.

Title: Regulating device for engine fuel injection apparatus
IPC: F02D1/00
Filed: 1941-09-11
Abstract: 549,344. Fluid-pressure servomotor-control systems. SCINTILLA, Ltd. Sept. 11, 1941, No. 11647. Convention date, Sept. 23, 1941. [Class 135] A servomotor regulating device for engine fuel injection apparatus fitted with a follow-up gear and controlled by a centrifugal governor and by manually actuated means has a transmitting lever arranged between the power device and the regulating organ of the fuel injection apparatus and connected by a manually adjustable connecting gear with a floating lever connected to the control valve and the governor sleeve. Figs. 1, 6, 7, 8 show two forms of the device particularly adapted for use in connection with engines used on motor vehicles. In the form shown in Fig. 1, the rod 8 of the double-acting power piston is connected by a pin 7 and slot 6 with a lever 4 turning on a stationary pivot 5 and connected by a pin 3 with a rod 1 operating the regulating organ of the fuel injection apparatus. The power piston is controlled by a piston valve adapted to connect passages 17, 18 leading to the power cylinder alternately to a pressure supply pipe 2 or to atmosphere. The valve rod 24 is connected to an intermediate point 39 of a floating lever 38 one end of which is connected to a sleeve 37 actuated by a centrifugal governor while the other is connected by a link 45 to a bell-crank lever 46 pivoted at 41 to the lever 4. The other arm of the bell-crank has a pin 47 slidably engaging a slot in an arm 48 mounted on a spindle 49 adapted to be adjusted by the attendant. The position of the parts shown in Fig. 1 corresponds to the position of rest in which the fuel supply to the engine is nearly interrupted. Rotation of the arm 48 in an anti-clockwise direction moves the control valve to admit pressure to the chamber 13 below the piston so moving the piston in the direction to increase the fuel supply. During this action the sleeve 37 of the governor rests on a shoulder 51. In the event of the speed determined by a spring 36 being exceeded the sleeve lifts away from the shoulder to move the control valve to connect the chamber above the piston to pressure so causing the piston to move downwards and reduce the supply of fuel. In the form shown in Figs. 6, 7, 8 the axes of the control valve and power piston are arranged at right angles. The transmitting lever 52 is rotatably mounted on a shaft 53 and has an eccentric boss 74 encircled by a sleeve 78 having an offset tubular extension 79 encircled by a sleeve provided with an arm 45 connected by a pin 40 to the end of the floating lever 38 remote from the governor. A slotted member 84 corresponding to the arm 49 is pivoted at 83 to the sleeve 78 and engages flats on the spindle 53 which is adapted to be rotatably adjusted by an arm 86 having a pin 87 connected to gear adapted to be actuated by an attendant. The action of this form is in all respects the same as that of the form first described except that the guide member is rotated in a clockwise instead of an anti-clockwise direction to increase the fuel supply.
