Title: Integrating circuit
IPC: H03K17/60
Filed: 1967-06-09
Abstract: 1,128,727. Integrators. NATIONAL CASH REGISTER CO. 9 June, 1967 [14 July, 1966], No. 26763/67. Heading G4G. An integrator comprises signal inverting amplifier 12 whose input and output are connected over a capacitor 16 and a shunting diode 32 with its anode connected to the input, which is connected to the cathode of diode 28 in series with resistors 26, 24 joined at 34 to a negativegoing input voltage on terminal 30a. Junction 54 is connected to positive source V2 over the collector/emitter circuit of PNP transistor 46 whose base is connected over resistor 58 to input terminal 66a, with a resistor 64 connecting it to a negative source V4 while the base is connected over resistor 60 to a positive source V3. The input of amplifier 12 is also connected to the cathode of diode 34 whose anode at junction 36 is connected to a positive source V1 over resistor 42 and to the anode of diode 38 returned to input 40a. It is shown that for a negative-going input at 30a, the output becomes positive and capacitor 14 acquires charge representing the integral of the input, and a positive reset signal from external circuitry applied to normally negative input 40a reverse biases diode 38 to cut off, whereby junction 36 becomes positive to forward bias diode 34 so that current from V1 discharges capacitor 16, and diode 32 prevents the capacitor acquiring reverse charge. A negative gate signal applied to normally earthed input 66a biases transistor 46 to saturation, thus interconnecting V2 and junction 54 to reverse bias diode 28 and shunt the information signal to earth over the transistor, while diode 28 isolates voltage variations in the collector/ emitter path from the integrating amplifier. In a modification (Fig. 2, not shown) a NPN transistor is used and all diodes and polarities are reversed, to accept positive-going input signals integrated to negative-going output signals. In a further modification (Fig. 3, not shown) the transistor emitter is earthed and the diode between the amplifier input and junction 54 is removed, while the capacitance shunt diode is returned to junction 36.

Filed: 1926-11-01
Abstract: 271,398. Westrnghouse Brake & Saxby Signal Co., Ltd., (Assignees of Grondahl, L. 0.). May 18, 1926, [Convention date]. Addition to 228,171. Electrical systems, automatic.-In a system employing thermosensitive relays as in the parent Specification, the heating element of each relay is in electrical connection with its thermosensitive element. This allows the elimination of one winding of the supply transformer, and necessitates the energization of only one relay at a time at the entrance to each section. The heating elements 8 are electrically connected to the thermosensitive elements 9 of the relays F<A>, H<A>, J<A>, K<A>, F<B>, H<B>, &c. of the sections, the circuit arrangements of the line sections being similar. When the relay J<A> or KA is energized, the corresponding lamp G<A>, Y<A>, is lit, the circuit being from secondary 11 of transformer TA over wire 36, lamp G<A> or Y<A> and relay J<A>, K<A> to common terminal d, thence over wire 39, heater of relay H<A> and resistance 24. The danger lamp R<A> is supplied from secondary 12 over heater of relay FA and part of resistance 24, the adjustment being such that if either of the lamps G<A>, Y<A> is energized, the potential drop across the part of resistance 24 due to secondary 12 is equal and opposite to that due to transformer 11. Lamp R<A> and relay F<A> are thus de-energized. As shown, the vehicle V shunts relays J<A>, K<A> so that lamps G<A>, Y<A> are both extinguished and relay H<A> de-energized, whilst lamp RA is lit and relay F<A> energized. Current of reverse polarity is therefore supplied to the rails 1, 1<a> of section AB from secondary 14 over asymmetrical unit 6, relay F<A> wire 50, and over wire 51. This current energizes relay K<B> through asymmetrical unit 5. but is unable to energize relay J<B> through asymmetrical unit 4. Lamp Y<B> is thus lit, and relay H<B> energized, whilst lamp R<B> and relay Fs are de-energized. Current of normal polarity is therefore supplied to section BC from secondary 15 to transformer T<B> over asymmetrical unit 7 and relay HB. Relay Jc is thus energized, energization of relay Kc being prevented by the corresponding asymmetrical unit. The "proceed" lamp G<C> is thus lit, relay H<C> energized, and current of normal polarity supplied to the section to the right of BC.
