Abstract: 981,922. Electrical digital calculators. RADIO CORPORATION OF AMERICA. Sept. 24, 1962 [Oct. 17, 1961], No. 36293/62. Heading G4A. Carry circuits in a parallel adder comprise three gates and produce carry and inverse carry signals at alternate circuits. Each gate e.g. 20 produces a high level output when all the inputs are at low level and vice-versa. At circuit C1 the operand digits are inputs to gate 24 and their inverses to gate 20. An in-carry and the output of gate 20 is applied to gate 22. The output of gate 22 or gate 24 gives the inverse carry. C2 is of similar construction but gate 30 receives the operand digits and gate 34 their inverses. As before the outputs of gates 32, 34 give a carry signal but in this case a true carry. The outputs of circuits 32, 34 are separate inputs to gate 42 of circuit C3. A "rippling" carry signal need pass through only one gate of each circuit.

Title: Measurement classification apparatus
IPC: G01R29/00
Filed: 1966-08-16
Abstract: 1,113,770. Analogue-to-digital converters. BROOKHIRST IGRANIC Ltd. 16 Aug., 1966 [2 Sept., 1965], No. 36615/66. Heading G4H. [Also in Division G1] An apparatus for classifying a measurement according to its magnitude, e.g. whether it lies under, over or within a given range makes use of an A.C. bridge circuit 2, 18, 21 which when unbalanced provides an A.C. output whose phase depends on the sense of unbalance. Part of the bridge incorporates a transducer 2 to provide a variable impedance in accordance with the quantity to be measured, while a further part 18 may be altered stepwise by switching in a resistor 19. The bridge output at 20 is sampled by a switching signal in phase with the bridge supply and applied via transistor 27. If the signal is antiphase with the supply indicating that the output variable is greater than the value which would balance the bridge set to the lower end of the acceptable measuring range positive going pulses are produced by the pulse amplifier 26 each time the transistor is switched. These are gated at 31 with clock pulses and provide shift pulse to a pair of coupled flip-flops 35, 36, which have previously been set so that 35 is in a " 1 " condition, 36 in a zero condition. The transfer of the " 1 " to flip-flop 36 energizes a relay switch 23 to alter the bridge so that it will balance at the upper end of the acceptable measuring range. If now the input variable is below this value, in-phase signals appear at the bridge output and negative going signals are produced by the amplifier 26, which do not step the flip-flops. Thus flip-flop 36 remains in a " 1 " condition and passes a signal to an " O.K." indicator 44. If, however, the pulses are still positive-going the shift pulse alters the flip-flop 36 back to the zero condition. The two zero outputs, from 35 and 36 are AND gated together at 51 to actuate the "over" indicator 45. If no shift pulse appeared originally, the " 1 " output of flip-flop 35 actuates the " under " indicator 43. To carry out a further measurement the flip-flops are reset by a pushbutton controlled generator 55. The system may incorporate a number of switchable resistors 19 and operate as an analogue-digital converter.

Title: Improvements relating to the ventilation of enclosures
IPC: F24F11/02
Filed: 1929-12-09
Abstract: 344,914. Ventilating enclosures. CARRIER ENGINEERING CO., Ltd. and SAINTY, C. L., 24, Bucking- ham Gate, London. Dec. 9, 1929, No. 37718. [Class 137.] Relates to methods of controlling a ventilating air stream of sensibly constant density. Where a main air stream supplies a number of enclosures means are provided for maintaining constant the difference between atmospheric pressure and the total or static pressure in the main duct irrespective of variations in the amounts of air taken by the individual enclosures. In the case of a single stream the quantity and velocity of the air supplied are maintained constant. As shown in Fig. 1, a fan 1 draws fresh air from an inlet 2 past a conditioning device 3 or past a heater 3b and air for recirculation from a duct 4 and delivers the mixture to a series of enclosures 8, 9, 10 through a main duct 6 and secondary ducts 7. Air is withdrawn from the enclosures by a fan 11 through a main duct 12 and secondary ducts 13. Manually or automatically adjusted dampers 15, 16 regulate the air supply to the individual enclosures and may be so arranged that atmospheric pressure or a pressure slightly above atmospheric is maintained. In a modification the recirculation duct 4 is omitted. In order that an alteration in a damper 15 of one enclosure may not affect the air supply to the remaining enclosures, a pressure regulator 20 responsive to the total or to the static pressure is fitted within the main duct 6 and actuates a damper 24 to maintain constant the difference between the said duct pressure and the pressure of the still atmosphere. A similar control system may be located in the main extraction duct 12. The regulator 20 is connected to the inside of a bellows forming a diaphragm valve 21, the exterior surface of the bellows being exposed to atmospheric pressure. Any change in the pressure difference allows more or less compressed air from a supply 22 to pass to an air lever motor 23 operating the damper 24. For maintaining a constant supply in a duct, the regulator is responsive to pressures at different points and operates differentially to vary the resistance such as a damper 40, Fig. 6. As shown in Fig. 7 the regulator is responsive to the difference between the static and total pressures of the air stream.

Abstract: 1,133,536. Selective signalling. INTERNATIONAL STANDARD ELECTRIC CORP. 17 Aug., 1967 [19 Aug.. 1966], No. 37859/67. Heading G4H. Actuation of 2 out of n keys K places corresponding relay coils RK in parallel in one arm of a bridge whose other arms comprise resistors R2-R5 and the resulting voltage across diagonal 1, 2 cuts off T causing successive operation of TP, H1, H2 and An. Operation of H2 restores T to the conductive state by shorting R5, and subsequent operation of An allows an external circuit including contacts of RK to be operative. If less than 2 keys are actuated T is not cut off, but if more than 2 keys are actuated, T remains cut off when H2 operates to short R5 so that H1 and H2 remain energized and prevent actuation of An. The keys may be arranged in two separate groups. When a key of the further group is pressed, GT1 opens to insert R1 in the bridge, the value of R1 being equivalent to the resistance of a single coil RK, so that the circuit only provides an output when one only of the keys in the first group is pressed.
