Abstract: 645,184. Current and voltage measuring. SANGAMO WESTON, Ltd. Dec. 30, 1946, No. 38066. Convention date, April - 18. [Class 37] [Also in Group XL (c)] A direct-current instrument amplifier comprises a pair of valves to one of which the input signal is applied and which are cross connected between anodes and grids to give a positive feed-back loop, each valve having a negative feed-back circuit from its anode to control grid, in this way improved stability and accuracy of calibration are obtained. Fig. 3 shows an amplifying circuit in which the input is applied via terminals 2, 2 to the amplifier valve V which is connected as an anode-follower with negative feed-back from anode to control grid. Valve V1 also connected as an anode-follower completes the bridge-type circuit in which positive feed-back is obtained by the cross connections between anodes and screen grids. Resistor 9 is adjusted so that maximum gain is obtained without the amplifier becoming unstable and potentiometer 10 enables the operating points of the two valves to be balanced. In a modification, Fig. 4 (not shown), which is operated from the rectified A.C. mains supply the bias batteries 1, 11 of the circuit of Fig. 3, are replaced by small gas voltage regulator tubes which are returned to the cathode of the respective valve via individual cathode resistors. In a further modification, shown in Fig. 5, the output load and regulator tube current are removed from the regenerative portion of the circuit by following both the amplifier and reference valve by cathode follower buffer stages 15, 15<SP>1</SP>, thus enabling the circuit to be loaded without preventing critical regeneration from being obtained. In a further modification, Fig. 6 (not shown), the indicating millivoltmeter is replaced by a milliammeter the amplifier acting as a voltage input-current output type. Further modifications, Figs. 7, 8 (not shown), enable the amplifier to operate as a current input-voltage output or current input-current output instrument respectively.

Abstract: 353,816. Master control of several motors. SUNDERLAND FORGE & ENGINEERING CO., Ltd. and PFOB, S., St. Luke's Road, Pallion, Sunderland. Dec. 17, 1930, No. 38078. [Class 38 (iii).] In a starting system for a number of motors in which each motor in turn is first connected to a common starter, and when up to speed is transferred to the supply mains, a common resistance is provided so that when an attempt is made to start two or more motors simultaneously or to start one motor before a second has been brought up to speed, the current is insufficient to operate the motor contactor coils. When a button A is pressed, coils s, n are energized by a circuit passing through the common resistance K. Switches S<1>, N<1>, W close, and the motor M receives current through a starting resistance R. When the switch S<1> closes auxiliary switches s<1>, s<2> close, the former completing a maintaining circuit for the coils u, s through a coil t, independent of the button A. The switch T therefore closes to energize coils V, E, the former actuating the plunger v<1> to cut out the resistance R at a rate regulated by the coil E. When all the resistance is out and the motor M is up to speed, contacts 13, 14 are closed and a circuit is completed for a coil p through switch s<2> and resistance K. As a result the switches P<1>, p<1> are actuated, the former placing the motor M across the supply mains and the latter de-energizing the coil s but closing a maintaining circuit for the coil p, n. When the switch S<1> opens switches s<1>, s<2> also open, the former de-energizing the coil t and breaking the circuit for coils V, E, so that the apparatus is ready for starting a second motor. Specification 324,360, [Class 38 (iii), Electric motor control systems &c.], is referred to.
