Title: Fast acting direct current clamping circuits
IPC: G11B20/00
Filed: 1974-05-09
Abstract: 1423319 Clamping circuits AMPEX CORP 9 May 1974 [14 June 1973] 20423/74 Heading H4F A clamping circuit operating to clamp the video signal at point 62, Fig. 3, to a clamp reference voltage supplied to a comparator 64 includes a holding capacitor 68 connected to point 62, the holding capacitor, during each line synchronizing interval, being first charged negatively by a negative current source 67 in response to a signal from control logic 65 to a voltage lower than that corresponding to the clamp reference voltage, and subsequently being charged positively by a positive current source 66 in response to a further signal from control logic 65, the positive charging being stopped when comparator 64 detects that the voltage at point 62 corresponds to the clamp reference voltage. Each horizontal synchronizing pulse separated by sync stripper 50 produces pulses on lines 101, 102, Fig. 5, forming part of the control logic 65, which pulses set monostable multivibrator 106 to enable AND gate 104 and hence activate negative current source 67; the output of the multivibrator 106 further sets flip-flop 111 and disables AND gate 103. When monostable multivibrator 106 resets, after less than half the horizontal sync pulse interval, AND gate 104 is disabled, negative current source 67 is deactivated, and AND gate 103 is enabled, due to flip-flop 111 being set, to activate positive current source 66. When comparator 64 detects that the voltage at point 62 corresponds to the clamp reference voltage AND gate circuit 83<SP>1</SP> provides a pulse to reset flip-flop 111 and so disable AND gate 103 and deactivate positive current source 66, holding capacitor 68 maintaining its voltage during the following line scan period.

Filed: 1931-07-17
Abstract: 375,099. Lubricating vehicle chassis. DURRANT, A. A. M., 17, Sutton Court, Chiswick, London, and LONDON GENERAL OMNIBUS CO., Ltd., 55, Broadway, Westminster. July 17, 1931, No. 20501. [Class 12 (iii).] In a lubricating system for a vehicle chassis, an oil reservoir 1 is subdivided by internal partitions 2, 3 into a number of compartments each of which has an outlet conduit 6 screwed through the bottom wall and connected by a coupling 15 to a pipe line 14, the mouth of each conduit 6 being in the form of a valveless nipple 7 adapted to be engaged by the nozzle of a pressure gun. Oil is thus normally fed by gravity to the pipe lines, but a gun may be engaged temporarily with any one of the nipples 7 if the associated pipe line is blocked or an extra flush of oil is required. The partitions 2, 3 stop short of the top of the reservoir, so that all the compartments can be filled simultaneously. The bores of the conduits 6 or pipe lines 14 may differ according to the feed required, and the capacities of the various compartments may differ accordingly, whereby they will all be ready for filling at approximately the same time. Thus, the bottom walls of the compartments may vary in thickness while the compartments have the same cross section. The reservoir is provided with a hinged lid 20 fitted with spring fingers 25 adapted to engage internal projections 26 in the reservoir. A plate 36 mounted on the lid is provided with legends over each compartment denoting the parts to be supplied thereby. A number of reservoirs are mounted on various parts of the chassis, being secured by brackets 27 through which some or all of the conduits 6 extend.

Title: Voltage limiting device
IPC: G05F3/04
Filed: 1951-09-07
Abstract: 693,085. Voltage limiter circuits; modulating apparatus. BENDIX AVIATION CORPORATION. Sept. 7, 1951 [Sept. 30, 1950], No. 21162/51. Classes 40 (v) and 40 (vi). A voltage limiting device for an A.C. input signal comprises a parallel network having oppositely disposed rectifiers which are fed with pulsating voltages of opposite polarity, and having the same frequency as the signal, the input being applied through an impedance to one end of the network and the output being taken from across the network. In Fig. 1, a sinusoidal signal voltage is applied to terminals 27, 29, and a reference voltage of the same frequency and which is in phase or 180 degrees out of phase with the signal voltage, is applied to transformer 3. After full-wave rectification, the reference voltage is applied across a resistance 13, the centre tap of which is connected to terminal 27, so that, measured from this terminal, the potentials of the ends of resistance 13 are varying sinusoidally in opposite phase. Oppositely arranged rectifiers 30, 31 are connected between the ends of resistance 13 and a resistance 33 connected between the input terminal 29 and output terminal 28. The arrangement is such that while the input voltage is less than that appearing across each of the halves of resistance 13, rectifiers 30 and 31 do not conduct, and the output signal corresponds to the input signal. When the signal voltage exceeds that appearing across each half of resistance 13 the diodes 30 and 31 conduct alternately, corresponding to successive half cycles, and limit the amplitude of the output signal by producing a potential drop across resistance 33. In this way, the output is always an undistorted sine wave, even when limited to the amplitude of the waveform across each half of resistance 18. It is stated that the arrangement may also be used as a modulator, the modulating voltage being applied to transformer 3 and the carrier being applied to terminals 29 and 27.
