Abstract: 1324378 Programmed control WESTING- HOUSE ELECTRIC CORP 30 Sept 1970 [21 Oct 1969] 46525/70 Heading G3N An interface circuit between a control computer and a controlled load comprises an integrator circuit which is convertible into a voltage following circuit whereby the load can be controlled from an alternative voltage. A process or machine tool control system which is responsive to time-shared signals on a line 32 includes an interface circuit comprising as shown, a MOSFET amplifier 42 cascaded with a DC operational amplifier 46. During the input of control pulses from the computer a gate control 60, responsive to a gating pulse on line 62, closes IGFET switches 36, 38 so that the amplifiers 42, 46 by a feedback capacitor 64, integrate the incoming pulses and memorize the integrated value when switches 36, 38 open. During manual or automatic control a signal on a terminal 66 or 68 closes switch 38 and changes over switches 50, 54 so that the amplifiers 42, 46 cease to operate as an integrator and become a voltage following circuit, the voltage on the capacitor 64, through the coupling resistor 48, varying with the signal on a line 58. On resumption of computer control switch 38 opens and the charge on capacitor 64 is maintained in readiness for the next time-shared computer pulse-train. A line 72 provides a voltage reference point for the computer 10.

Apparatus for exploding a number of seriesconnected detonators 2 comprises a source of energy 1 to which the detonators are connected by way of a diode 8 and a gas-filled electronic switch 7, the source of energy 1 being of the kind in which the potential increases gradually from a minimum to a maximum value at a given point in which range a cold cathode gasfilled triode 11 becomes conductive whereupon the potential of a terminal 12 suddenly changes from an initial negative potential 13 to a positive potential, the pulse being transmitted by a condenser 15 to the anode of the switch 7 causing it to conduct to explode the detonators 2. The change of potential at the terminal 12 also causes a diode 19 to fire, after a time interval determined by the resistor-condenser network 16, 18, so that a pulse is applied to the firing electrode of a silicon controlled rectifier 21 which then becomes conductive to short-circuit the supply 1 at terminals 5d, 6c whereupon the voltage of the source diminishes and the switch 7 becomes non-conductive. In other embodiments the terminals 5d, 5e, 12, 20 are connected into the circuit by way of additional resistors, condensers and diodes to ensure short-circuiting of the source 1 should any element of the system become unserviceable thus preventing damage due to undesired explosions of the detonators 2.

Abstract: 1,072,720. Semi-conductor switching circuits; automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Nov. 18, 1965 [Nov. 19, 1964], No. 49117/65. Headings H3T and H4K. A logic AND circuit (Fig. 3) operative only if the input signals occur in order and suitable for use in a telephone line identifier comprises a number of semi-conductor bidirectional bistate devices T connected in series with a resistance Rc across a voltage source E1 with an input connection at each junction and with a further such device T u  connected to the resistor junction. In operation, when K5 is made, the operation of K4 will cause T4 to break down because the sum of E1 and E2 exceeds its threshold voltage. The operation of K3 will now break down T3 since the voltage E1 and E2 is connected across it. Operation in turn of K2 and K1 will break down T2 and T1 and the resulting voltage change will break down T u  to produce an output voltage step at U. The devices T1-T4 may be of the type which become bi-directionally conductive when a threshold voltage is exceeded and which become non-conductive when a holding current is removed. The devices may alternatively be of the type described in Specification 1,070,411 which have a low resistance crystalline state or a high resistance amorphous state depending upon whether a " setting " current decays quickly or slowly. With the second type the contacts K1-K4 need not remain " on " since the elements remain in " set " and " reset " states. Fig. 4 shows a telephone line identifier using the second type of element but which may be adapted to use the first type. Each line is associated with a unit L104, L105 &c. each comprising a chain M1-M3 as described with reference to Fig. 3. Operation of relay B makes contact E1 and a units selector V3 commences to step. When it reaches for example step 4, device M3 breaks down sending a signal back through the selector to the marker M to note the number of the contact and initiate the stepping of the tens selector V2 which in turn initiates operation of the stepping of the hundreds selector VI the selected steps being in turn noted by the marker. When all of M1-M3 have broken down the device T also breaks down to apply a voltage step to. the market to indicate that identification is complete. Capacitors C1 to C3 ensure that the pulse applied to the devices M have the required slow decay and resetting is effected under the control of the marker by operating a relay W to provide a reset pulse with the required steep decay.
