Title: Improvements in and relating to control gear for electric motors
IPC: B66B1/12
Filed: 1938-05-09
Abstract: 514,540. Control of A.C. motors BRITISH THOMSON-HOUSTON CO., Ltd., PETCH, T. H., and LIDDIARD, H. W. C. May 9, 1938, No. 13836. [Class 38 (iii)] Non-regenerative braking.-Dynamic braking of an induction motor is produced when the control lever is moved first to "off" position and then in either direction from 'that positon with the motor still running. As shown the coils of the main forward and reverse contactors, 1 and 2 are interlocked mutually and with 3, the coil of the contactor connecting one of the windings of the induction motor to a D.C. supply, to give dynamic braking, by the interlocking contacts 1a, 2a, 1b, 2b and 3a. 1c and 2c are open when their respective contactors are open and 3b is open when the main dynamic braking contacts are open. Contacts 4, 5, 6 and 7 are situated on a master controller operated by the driver's control lever. 4 and 5 supply current to the contactor coils 1 and 2 respectively while 6 and 7 are for the operation and interlocking of 3. To produce dynamic braking, the push button 8 is closed and the controller removed from either the forward or reverse position to the " off " position. Either 1 or 2 is de-energized and either 1b or 2b will close, completing a circuit through 3, 8 and 7. This closes the dynamic braking contacter and any further movement of the controller in any direction maintains this circuit through 6 and 3b, which closed when 3 was energized. The correct amount of resistance is kept in the rotor circuit automatically by the change in position of the controller and if the dynamic braking contactor opens for any reason neither the forward or reversing contactors can close by reason of an interlock. The dynamic braking may also be introduced either by a centrifugal device depending on the speed of the motor or by a device whose action depends on the direction of operation of the controller. A further circuit may be added to limit the motor speed when the load is being taken off. Specification 512,237 is referred to.

Abstract: 740,486. Electric tests. TINSLEY (INDUSTRIAL INSTRUMENTS), Ltd., and KERSHAW, P. L. April 28, 1954 [May 18, 1953], No. 13932/53. Class 37. [Also in Group XL (b)] The anode current of a valve is automatically balanced against the first derivative of the polarographic current of a cell by a photoelectric control circuit, and is recorded. As shown, light from a lamp 11 is reflected by the mirror 10 of a galvanometer 8 on to a photoelectric cell 18 controlling the bias on a valve 16. Deflection of the galvanometer is produced by voltage which is the algebraic difference of the P.D. across a resistor 24 in the anode circuit of valve 16, and a resistor 6 in the circuit of a polarographic cell 1 containing a dropping mercury electrode fed with a sweep voltage from the slider 4 of a potentiometer 2 connected across a battery 3, the sHder 4 being driven at constant speed by a motor 5. A change in voltage across resistor 6 produced by a change in the differential of the polarographic current from cell 1, causes the galvanometer mirror 10 to rotate to vary the light falling on the photo-cell 18 until the valve anode current again produces voltage balance in the galvanometer 8. The valve anode current after smoothing operates a pen recorder 23. To record the polarographic current directly, the differentiating circuit 6, 9 is omitted by changing a switch 7 from contact B, as shown, to contact A.

A fire detection apparatus comprises a mercury switch having a U tube a containing mercury into the lower part of which passes an electrode b of an electric alarm circuit, the two legs i, j of the U being connected to bulbs c, d respectively which bulbs are themselves connected by a tube e having a constriction f therein to restrict the flow of a fluid along the tube, a second electrode h being placed in the wall of an upper portion of either of the two legs of the U tube. Instead of the constriction f the tube e may contain a porous plug. In use the bulb c is exposed at the point where it is required to detect a fire whilst the bulb d is shielded so that as the temperature, around bulb c rises the fluid therein expands and displaces the mercury in the U tube thereby breaking the circuit between band hand raising an alarm. If the electrode h is placed in leg of the U tube above the surface of the mercury displacement of the mercury will complete the alarm circuit. A constriction may also be placed in the lower part of the U tube to prevent surges of the mercury column.
