Title: A memory device for a calculating machine
Inventor: GANG HERMAN
IPC: G06C21/04
Filed: 1967-12-19
Abstract: 1,137,729. Program control device. LITTON BUSINESS SYSTEMS Inc. 19 Sept., 1967 [20 Sept., 1966], No. 42656/67. Heading G4B. A calculating machine is provided with a control device programmed in response to a sequence of operations initiated by the function keys whereby the sequence of operations may be repeated any number of times under the control of said device. Program control device.-The program control device comprises function slides 7, program terminating slides 8, and repeat control slides 9 supported by spaced discs 10 on a shaft 4. The slides are held in their adjusted positions by flexible teeth 12. The shaft 4 is rotatably and slidably mounted in end bearings and spring-urged to a home position. The slides 7-9 co-operate with the teeth 18t of a stationary comb, feelers 19a and bails 20, 21. Programming cycle.-On depressing a function key, the shaft 4 is moved to the right, the slides 7-9 being prevented from moving by the teeth 18t whereby they take up an operative position on the shaft. The feelers 19a, other than the feeler corresponding to the depressed function key, are lowered to engage the left side of the function slides and the shaft 4 moved to the left to return the corresponding function slides to their inoperative positions. The slide 9 is likewise moved to its inoperative position by bail 21. The function slide 7 corresponding to the depressed function key and the slide 8 remain in their operative positions. The shaft 4 is indexed a step to bring the next row of slides into position. Bail 20 has a lobe 20c positioned forwardly of the slide 8 and is lifted by the slide 8 in its operative position when the device is rotated. When the device is moved to the right at the second operation, the bail 20 drops to bring the lobe adjacent the slide 8 in the first row. On restoring the device, the bail resets the slide 8 in the first row to its inoperative position. Thus the slide 8 moved to its operative position at one step in the programming cycle is restored to its inoperative position at the next step whereby only the slide 8 at the final step in the program remains in its operative position. The bail 21 is held clear of the slides 9 at the start of each operation, being released on depression of the digit keys. If operation of a function key is not preceded by depression of the digit keys, the bail 21 remains in its raised position whereby the slide 9 is not moved from its operative position. Operation.-Following a first calculation during which the device is programmed, the calculation is repeated by entering a value on the digit keys followed by depression of a master key, or where a step in the program does not require digit entry, simply depressing the master key. The feelers 19a are lowered to sense the slides 7, an operative slide 7 pivoting a feeler to depress the associated function key. Operation of bail 21 by a slide 9 maintains a single revolution clutch in engagement for a second cycle and operation of bail 20 by a slide 8 restores the device to its home position.

Title: Drive for electric circuit-breakers
IPC: H01H39/00
Filed: 1972-09-21
Abstract: 1391919 Actuation of switches B B C BROWN BOVERI & CO Ltd 21 Sept 1972 [23 Sept 1971] 43763/72 Heading H1N A mechanical drive for a circuit breaker has, as shown in Fig. 1, an operating rod 14b attached to a piston 14 which is moved in alternate directions in a cylinder 14a by gas pressure generated from the detonation of cartridges 11 accommodated in stationary magazines formed by bores in end flanges 10 each flange carrying a spring-driven rotatable part 22 having a striking lever 9 together with a gas-pressure controlled locking device (spring catch 18 and grooves 21) which governs the presentation of a fresh cartridge after each detonation. The striking mechanism comprises an annular armature 8 with associated push rods 8a which is normally held in a restrained position by a permanent magnet 7 against the action of a spring 24 (R.H.S. of Fig. 1) and is released by momentarily weakening the magnet field by energizing an electrical control coil 26. When so released the armature moves against the striking lever 9 (L.H.S. of Fig. 1) carried on an arm 22a and one of the cartridges in the magazine is detonated. Apart from the shaping of the chamber 5 or 6 defined by the end flange 10 and the open end of the cylinder 14a the arrangement at each end of the cylinder is identical and the pressurized gas produced by the detonation is introduced both for the main drive and for auxiliary functions by means of various ducts which serve as communicating passages within the flange and the rotatable part. Immediately the gas pressure builds up in the chamber 5 (or 6) the piston 14 starts to move the operating rod 14b and the push rods 8a are actuated via duct 15 to restore armature 8 to its magnetically attracted position, but when the piston uncovers vents 19 the gas pressure on its driving side falls and permits spring 20 to move parts 17, 17a against the lowered pressure in duct 16 to release spring- loaded catch 18 following which part 22 is moved by spiral spring 23 to rotate one step as determined by grooves 21 (Fig. 3a) and restoration of catch 18 by its own spring, thus presenting a fresh magazine cartridge position. The storage facilities of the magazines may be increased by using staggered bores 1 and 2 and a modified striking lever 91 as shown in Figs. 2 and 3. Chambers 5 and 6 may have different volumes so that, with identical cartridges, the driving energy imparted to the piston 14 may be different in the alternate directions.
