Title: Improvements in and relating to electrical control circuits

Filed: 1965-01-28
Abstract: 1,097,944. Firing circuits for thyristors. MATERIEL ELECTRIQUE S.W. Jan. 28, 1965 [Jan. 28, 1964], No. 3906/65. Heading H3T. [Also in Division H2] A firing circuit for a thyristor comprises two transistors T1 and T2 of opposite conductivity types supplied with antiphase outputs from an inverter 2 via rectifiers D1-D4. The transistors are gated by pulses from a control unit 5 and these pulses are in turn gated by transistor T3 supplied with pulses from a further control unit 8. When these pulses are not applied to T1 and T2, the former is cut off, but T2 conducts by a circulating current through the gate/ cathode path of the thyristor and resistors r and rb. This current biases the thyristor gate negatively to hold it off. When the firing pulses from 5 get through, T2 is cut off and T1 is turned on to bias the thyristor gate positively and cause it to conduct. The invention is applicable to the firing of a number of thyristors in series/parallel arrangement, the above circuit being duplicated for each thyristor but using the same primary winding of transformers 3, 7 with multiple secondaries. Thus, two groups of twenty-four thyristors can be used to control a D.C. motor.

Abstract: 1,216,571. Photographic camera. EASTMAN KODAK CO. Jan.25, 1968 [June 26, 1967], No.4009/68. Heading G2A. A photographic camera has means for winding film from a supply member past an exposure position to a take-up member and means for subsequent rewinding, and includes metering means responsive to advancement of the film, disabling means associated with the metering means and arranged to stop the film advancement after a predetermined number of exposures, the metering means being unresponsive to rewinding. As shown in Fig. 1, during winding, rotation of a winding knob 33 rotates a shaft 41, and by the engagement of a pin 48 with a stud 49 on a take up core 27 film 14 is drawn from a supply cassette 16 past an exposure lens 15. Engagement of holes 61 in the film with sprockets 59 rotates a pin 62, on a sprocket shaft 57, thus disengaging the toothed end 64 on a pawl 63 from a tooth on a metering member 53, Fig.2, each revolution of the sprocket causing the metering member to rotate by one tooth to move a dial 55 on the meter by one unit, the dial being set manually during loading to align the required number of exposures with a reference mark 69. When all of the available exposures have been made a tongue 81 on a slide 71 enters a notch 84 in a groove 83 in the meter 53, and the slide 71 moves leftwards, allowing lead 74 on shaft 41 to move downwardly so that pin 48 engages a stud 51 on a gear 35, and further rotation of the winding knob rotates cassette 16 through a geartrain 35, 24, 23, 19, to rewind the exposed film, the sprocket shaft being disengaged from the meter during rewinding. A lever may be substituted for the winding knob, or the driving member may be power operated.
