Abstract: 893,152. Spring motors. AGFA A.G. March 24, 1959 [March 29, 1958], No. 10245/59. Class 10. In a clockwork cine-camera de-energization of the spring is limited by the abutment of a stop-pin 24, Fig. 1, on a sun-gear-wheel 23, freely rotatable about the spring winding-shaft 4, against the inclined surface of a detent 25 of a pivoted lever 17 so as to move a projection 16 on the lever into the path of a projection 15 which is fast on a shaft 13 being rotated by gearing 14, 12. The gear teeth 12 are carried by the rotatable spring housing 9 and the drive to the camera mechanism is through the interengagement of these teeth with the gear teeth 14. The wheel 23 is arranged to rotate through less than one revolution from the " spring fully wound " pin 24 position of Fig. 2 to the " stop " position of Fig. 1. by double sun and planet gearing 11, 21, and 23, 22, the sun-wheel 11 of which is fast with the shaft 4 whilst the planet wheels 21, 22 are rigidly mounted on a shaft 20 carried by the spring housing 9. In the pin position of Fig. 2 the engagement of the lever and the pin prevents over-winding. As the pin is in constant positive connection with the spring housing 9 through the wheels 23, 22, 21, 11 and the shaft 4 it gives an indication of the .tension of the spring at any instant by its relative position with respect to a fixed point on the camera.

Abstract: 737,420. Digital electric calculating-apparatus. RADIO CORPORATION OF AMERICA. April 15, 1953 [May 24, 1952], No. 10366/53. Class 106 (1). [Also in Groups XXXVIII and XXXIX] In a magnetic switching system comprising input and output coils inductively coupled to magnetic cores 10 in accordance with first and second combinational codes respectively, current applied to selected input coils causes a change-over in magnetic polarity of one core and produces current in the output coils in dependence on which core is changed. In the binary adder shown, signals representing addend, augend and carry digits are applied to double triodes 80a, 80b, 82a, 82b and 84a, 84b, having the input coils 70a, 70b, 72a, 72b and 74a, 74b in their anode circuits, to cause conduction in the left or right side to represent " 0 " or " 1 " respectively. The input coils are coupled to the toroidal cores 10 by windings 12 as shown, so that for each of the eight digit combinations only one core will have all its windings 12 energized and will thus be driven from a normai " N " saturation condition to the opposite P " condition thus inducing current in the appropriate output coils 142, 141 representing the sum and new carry digit respectively. These output coils are connected to output tubes 44 and are coupled by windings 42 to the cores for which an output is required. The cores may be restored to the " N " condition by exciting coil 18 via tube 28 controlled e.g. by a bi-stable trigger circuit. In a modification (Fig. 9, not shown) for adding two twodigit binary numbers and a carry digit to form a two-digit sum and new carry, five doubletriode input tubes are provided and each core has either a " P " winding like 12 or an " N " winding like 14 for each input coil. The switching system may be expanded to add two binarycoded decimal digits. Non-adding switching arrangements for translating from one binary code to another, and other arrangements of windings for the input and output coils, also are described. The input tubes may be replaced by further magnetic cores. Specification 725,689 is referred to.
