In the arrangement shown in Fig. 3 a single-control lever 30. pivoted at 23, has been moved to the right into an intermediate position in which cam rollers 20, 21 thereon are holding pivoted cam levers 18, 19 in a position in which the water outlet valve WO has not quite closed and the steam inlet valve SI has been partly opened for the scavenging operation. At the same time, a second similar set of cam rollers and levers, behind those shown, have closed the water inlet valve and arrived at a position in which the steam outlet valve is about to open. A further movement of the lever 30 to the right, as shown in Fig. 8, causes the roller 20 to release the lever 18 and allow the water outlet to close, and also causes the roller 21 to lift the lever 19 and open the steam inlet valve fully. Simultaneously the cam lever mechanism in the rear has opened fully the steam outlet valve. Upper rollers 25 on the single-control lever 30 operate on sets of levers 26, 27 which act through the cam levers 18, 19 to move the valves in the closing direction as allowed by the movements of the rollers 20, 21.

Title: Phase measuring apparatus
Inventor: LEE KENNETH WILLIAM
IPC: H04N17/02
Filed: 1963-07-01
Abstract: 980,014. Voltage measurement STANDARD TELEPHONES & CABLES Ltd. July 1, 1963, No. 26016/63. Heading G1U. [Also in Divisions H3 and H4] The ampltidues of a high frequency signal at different times are compared by gating the signal at these times, rectifying the outputs of the gates, and feeding the rectified outputs in opposition to a D.C. amplifier feeding a meter. The signal may be the colour television test signal shown in Fig. 1 and comprising a synchronizing pulse 1 and five steps 2-6, a colour sub-carrier being superimposed on the steps; it is desired to compare the amplitude of the colour sub-carrier at step 2 with the amplitude at step 5, for example. The signal is applied to a high pass filter 11a, which removes the step components and then passes through an amplifier to gates 12 and 13 which are opened respectively at times corresponding to steps 2 and 5 of Fig. 1. The outputs of the gates are rectified in units 37, stored on capacitors 38 and 39, and applied in opposite polarity to a D.C. amplifier 27 feeding a meter 28. The pulses opening the gates are derived from the synchronizing pulse in units 29-34, and for calibration purposes the gates may be opened synchronously. An attenuator 41 between gate 13 and rectifier 37 can be switched in steps and is ganged to an attenuator 40. With the same signal passing through each gate and attenuator 41 set to a desired value, the gain of amplifier 27 is adjusted to give full scale deflection on the meter 28. The gating pulse applied to gate 13 is then delayed by a desired amount to give the desired comparison.
