Patent GB-2077002-A (GB)
Title: Electronic timepiece comprising a control circuit of the motor
IPC: G04C3/14
Filed: 1981-04-07
Abstract: An electronic timepiece comprises a stepping motor having a winding 50, a discriminator 101 for analysing at a determined instant of time during the motor driving pulse the voltage drop across power transistors 10 or 13 controlling flow of drive current in the motor. The voltage drop is transmitted through transmission gates 16 or 15 to a capacitor 17 at the input of the discriminator. The capacitor memorizes this input voltage and the discriminator delivers an output signal according to the comparison of the value of the input voltage with its release threshold. Transistors 22, 23 controlled by control means are connected in parallel with the power transistors for adjusting the release threshold of the discriminator in such manner that the discriminator interrupts the driving pulse when the value C' Fig. 2 of the driving current is reached indicating that the rotor will achieve its step. <IMAGE>

Title: Apparatus for flow ratio control
Inventor: WATSON JOHN RICHARD
IPC: F23N1/02
Filed: 1982-11-12
Abstract: Apparatus for controlling the air/ gas mixture to a burner comprises a gas line 1 to which gas is supplied from a domestic gas meter at a constant pressure and an airline 2 to which air is supplied by a fan. The fan may deliver air at fluctuating pressures and the purpose of the apparatus is to smooth out these fluctuations. Lines 1,2, meet in a common outlet 3 which leads to a burner. Each line 1,2, comprises a valve 4,5, the valves being interlinked by a mechanical linkage 6 so that the valve opening areas are adjustable simultaneously. Gas line 1 incorporates a non-return valve 7. Airline 2 incorporates a fluid flow regulator valve 8 which responds to the air pressure upstream of the valve 5 via a tapping line 9 to maintain across the valve 5 a constant differential pressure. Valve 8 opens in response to decreased air pressure upstream of the valve 5 to increase air flow through the valve 8 and closes in response to increase air pressure upstream of the valve 5 to reduce air flow through the valve 8. Thus upstream air pressure fluctuations are smoothed out leading to the maintenance of a constant air/gas ratio. <IMAGE>
