Filed: 1973-05-15
Abstract: 1373480 Automatic frequency control INTERNATIONAL STANDARD ELECTRIC CORP 15 May 1973 [30 June 1972] 23014/73 Heading H3A A phase locked loop having a voltage controlled oscillator 6 and a phase comparator 4 which compares the oscillator output with a reference signal to produce a control voltage for the oscillator is characterized by the provision of pulse generators, e.g. monostables 10, 11, triggered by the reference signal and the oscillator output respectively, the outputs from the pulse generators being fed to a NAND gate 12 which blocks the output of the oscillator 6 upon the occurrence of a given logic condition at the NAND gate output. A phase shifter 9 is included in the input to one of the monostables so that when the reference and oscillator signals are in phase, the outputs from the twomonostables are phase displaced. Thus when ever a "1" appears a one input to the NAND gate, a "0" appears at the other, and the NAND output is "1". The output from the NAND gate is inverted by INVERTER 13 to provide a "0" at point E. If synchronization is lost, "1" pulses appear at point E and are integrated by capacitor 14. As soon as the voltage across this capacitor reaches the threshold of transistor 15, the latter conducts to inhibit the output from oscillator 6 by blocking dioder 3 or closing a gate, not shown. At the same time an alarm is sounded. The output frequency may be varied by a divider 2 in the loop.

Abstract: 1510779 Automatic control of temperature ASSOCIATED ENG Ltd 14 May 1975 [24 May 1974] 23439/74 Heading G3R [Also in Division F4] In a vehicle, air heating or cooling apparatus comprises a heat exchanger 16 selectively supplied with heated engine coolant through a line 20A from an engine cooling system 28 or with coolant taken from a return line 20B and passed through a line 19 including an evaporator 17 by a pump 22, according to the setting of a two-way valve 11. A valve 29 ganged to valve 11 may be located at the junction of lines 20B, 19. The heat exchanger 16, and optionally the valve 11, are located within the vehicle passenger compartment and the rate of heat transfer between the heat exchanger 16 and air delivered by a fan 10 is controllable by varying the speed of the fan drive motor 37. Alternatively, the heat exchanger 16 is located in a duct 41 having a by-pass 42, supplied with recirculated and fresh air via ducts 46, 47 and a fan 45, and a proportioning flap valve 49 is actuated by a motor 40. The valve 11 may be manually operable. An automatic control system for maintaining a required temperature in the passenger compartment controls the operation both of the two-way valve 11 and of the motor 37 or the motor 40. A thermostat 30 has its output, in the form of voltages proportional to the required and actual temperature of the passenger compartment respectively, applied to a comparator 31 which controls the rotational position of two cams 33, 34 via a motor 32 and a reduction gear device. The cam 33 has two opposed cam faces 33a, b engaged by a cam follower 35 which operates a rheostat 36 which controls the motor 37 or 40. The cam 34 has a step 34a and the pivotal movement of an arm 38a of a cam follower 38 is applied electrically to operate the valve 11. Upon a demand for heating, rotation of cam 33 causes follower 35 to move up surface 33b to increase the speed of fan 10 or to move valve 49 towards position A. As the demand for heating decreases, follower 35 moves down surface 33b to decrease the speed of fan 10 or to move valve 49 towards position B. When the required temperature is attained, the follower 35 is in the trough between surfaces 33a, b and the follower 38 has riden up the step 34a to switch the valve 11 to a cooling mode of operation. The fan 10 or valve 49 are then operated during the cooling mode as during the heating mode.
