Patent GB-2018470-A (GB)
Title: Temperature control apparatus
IPC: F24F11/00
Filed: 1979-03-30
Abstract: A temperature controller for an air-conditioner which has both heating and cooling modes uses a sensor to determine whether the outside temperature is within a predetermined range required for the air-conditioner to be operated in a cooling mode and governs the conditioner accordingly. The described controller uses sensors responsive to the outside and inside temperatures respectively, and a microcomputer which adjusts the set point T2 of an inside temperature control loop as a linear function of the outside temperature, when running in the cooling mode. The air-conditioner then operates as a cooler to bring the sensed inside temperature into correspondence with the set point. For outside temperatures between e.g. 20 & 27 DEG C, the arrangement operates in a ventilating mode in which it neither heats nor cools but a fan is operated. <IMAGE>

Patent GB-2039187-A (GB)
Title: Monopulse radar apparatus
IPC: G01S13/44
Filed: 1979-12-12
Abstract: A hybrid (amplitude-phase) monopulse direction finder uses overlapping divergent beams with spaced origins. Sum and difference signals ( SIGMA ,  DELTA ) are formed from the two received signals and the phase difference ( psi  DELTA  - psi  SIGMA ) between the sum and difference signals, as well as the amplitudes (¦E DELTA ¦, ¦E SIGMA ¦) are determined (in 20). The manner in which these determined quantities vary with deviation of the signal direction from the boresight is previously known, Fig. 3, as a characteristic of the antenna and the actual direction is determined from said characteristic. A signal may be tracked around a direction off the boresight by adding phase offset ( psi 0) to the phase difference determination and bias voltage (V0) to the boresight error voltage (V1). <IMAGE>

Patent GB-2109127-A (GB)
Title: Self monitoring control and sensing arrangement
Inventor: MILBURN ROBERT JOHN
IPC: F23N5/12
Filed: 1981-11-03
Abstract: A central control unit both controls and monitors gas boiler function by means of outputs R, S, V and inputs P, Q, W, X. A power supply 30, connected through a fuse 32, supplies power to the arrangement and to a pair of boiler gas inlet valves (having inputs B, C, D) controlled by the outputs R and S. The control unit periodically monitors its own function after a present count of pulses from oscillator 41 by causing the power supply to be short circuited through fuse 32 consequent to light 44 being activated to illuminate optical switch 34. Secondary transformer windings 45 act to sense current flow resulting from the short circuit and inform the control unit. Correct function of the arrangement causes deactivation of light 44, and hence switch 34, within a time period insufficient to melt fuse 32. Incorrect function isolates the gas inlet valves which are biassed shut. <IMAGE>
