Abstract: 542,688. Automatic control systems for electrically driven camera shutters &c. ELECTRICAL RESEARCH PRODUCTS, Inc. Oct. 7, 1940, No. 14958. Convention date, Oct. 12, 1939. [Class 38 (iv)]  Synchromism.-Rotating mechanisms driven by synchronous electric motors may be restored to a different phase relationship by a relay arrangement adapted to interrupt the supply circuit for the motor condenser for a predetermined time independent of the phase difference. A rotating contact segment 12 related to the position of a cine-camera shutter driven by a motor 11 momentarily energizes a relay 16 and charges a parallel condenser 18 which determines the period of closure of the relay directly phase synchronism is lost with a similar segment 3. The latter segment is driven in common with the shutter of a cinema projector for a background being photographed with local action. During synchronous conditions the segment 3 or equivalent means operates to open the circuit of relay 16 as by a relay 8. The relay 16 energizes a relay 22 which closes for a time determined by the discharge of a second condenser 21 to energize a relay 24 to open the circuit of the motor 11. Resistances 15, 23 determine the time constant of the condenser relay circuits ; for example they may be adjusted to permit the motor 11 to slip back through an angle equivalent to about two poles. The control action continues until phase synchronism is restored.

Title: Improvements in or relating to apparatus for testing electrical resistance
IPC: G01R17/10
Filed: 1953-06-01
Abstract: 743,223. Resistance measuring bridge. GENERAL ELECTRIC CO., Ltd., and WARD, P. W. June 1, 1954 [June 1, 1953], No. 15215/53. Class 37. Apparatus for testing electrical resistance comprises a Wheatstone bridge wherein the test resistance is in a first arm and selected values of resistance in the second and third arms determine the nominal value of the test resistance and the bridge-balance position of a continuously variable resistance in the fourth arm indicates the variation of the test resistance from its nominal value. The selected values of resistance in the second and third arms correspond to numerical values and decade factors through a range of nominal values of the test resistance. The product of numerical value and decade factor is equal to the nominal value of the test resistance. In the drawing a 12-way switch S2a, S2b in arm 2 selects one or more of resistors 12-19 to produce a desired numerical value of 1.0, 1.2, 1.5, 1.8, 2.2, 2.7, 3.3, 3.9, 4.7, 5.6, 6.8 or 8.2 (ohms) (corresponding actual resistance values: 10,000, 12,000 ... 82,000 ohms) and switch S3A selects in arm 3 one or more of the resistors 21-25 to produce a decade factor of 100, 1000, 10,000, 100,000 or 1,000,000 ohms so that the apparatus can be used to test resistance having any one of sixty nominal values between 100 ohms and 8.2 meg. ohms. If, for example, the test resistance in arm 1 (across terminals 11) has a nominal value of 8.2 meg. ohms S2 (arm 2) is set to 8.2 numerical value (actual value of arm 2 resistance: 82,000 ohms) and S3 (arm 3) is set to 1,000,000 decade factor so that the product of S2, S3 knob indices (i.e. 8.2 x 1,000,000) equals the nominal value of test resistance 1 and if the latter has an actual value of 8.2 megohms the resistance in the bridge balancing arm 4 is 10,000 ohms at bridge balance. The arm 4 comprises a fixed resistor 26 in series with balancing resistor 27 and if the test resistance 1 deviates from 8.2 megohms the adjusting member on resistor 27 is moved until the microammeter 5 gives zero deflection and the percentage error (between - 20 and +20) is then read off the calibration associated with resistor 27. The null meter 5 and series resistor 28 are shunted by back-to-back germanium diodes 29, 30 that the sensitivity of the meter 5 varies with the magnitude of the out-of-balance voltage. The connecting in of resistors 32- 34 by contact bank S3b limits the bridge supply voltage to ensure approximately the same bridge sensitivity for each of the decade factors 21-25 selected by S3a. The bridge is D.C. energized from across a smoothing condenser 6 which is fed from A.C. supply 9 through normally open switch contacts S1a, a transformer 7 and a selenium rectifier 8. When S1 is operated to close S1a the contacts S1b open to remove. the short-circuit across the null meter 9.
