Filed: 1954-12-10
Abstract: 768,176. Rolling; drawing. LAMNEA BRUK AKTIEBOLAG. Dec. 10, 1954, No. 35866/54. Class 83 (4). A wire-drawing machine has two or more draw plates 3, 4 and a corresponding number of drawing blocks 1, 2 which are driven by at least one differential 7 through gearing 16, 18 and 17, 19 having ratios arranged to give a selected back-tension P and also drawing forces of values nearly equal to the ultimate breaking strength of the wire. Expressed as an equation for a two block system: P 1 r 1 (D 1 -P) = P 2 r 2 (D 2  + P) = M 1  = M 2  where D 1  and D 2  are the drawing forces at the first and second draw plates, respectively, P is the back-tension, r 1  and r 2  are the radii of the first and second draw blocks, P 1  and P 2  are respectively constants representing the gear ratio of the gearing 16, 18 and 17, 19 with friction coefficients included, and M 1  and M 2  are the equal torques of the output differential shafts. The differential shafts 12, 14 drive the gears 16, 17 through friction clutches 13, 15 and shafts 20, 21 carrying the gears 18, 19 can be connected together by a manually or automatically operated clutch 24 so that if the wire breaks or its end passes out of the machine, the two output shafts can be positively interconnected. The gear ratios of the gearing 16, 18 and 17, 19 are such that, when the clutch 24 is engaged, the peripheral speeds of the drums are substantially correctly adjusted with regard to the increasing length of the wire 5 produced by the drawing operation but if these speeds are not exactly correct the wire can slip on the blocks. The invention is stated to be applicable also to rolling mills.

Abstract: 1,036,809. Statistical apparatus. SIEMENS & HALSKE A.G. Sept. 3, 1964, No. 36214/64. Heading G4M. In a machine for sorting perforated card strips of variable length, the sorting-flap 26, Fig. 2, of each compartment is opened by a solenoid 27 which also causes the floor of the compartment to be lowered by an amount equivalent to the thickness of a card strip each time the solenoid is energized. The floor of the compartment is formed by the top of a carriage 38 which is biased upwards by a spring 45 and a cord 46 which runs over pulleys 47. In the upper position, the carriage 38 is tilted so that a rack 39 is disengaged from a threaded spindle 40. When a number of card strips have entered the compartment, carriage 38 tilts back under the weight of the card strips and rack 39 engages spindle 40. Each time magnet 27 is energized, a cord 50 raises a lever 51 so that a further lever 54 engages a pin 55. When a further magnet, which is common to all the compartments, is energized towards the end of a card cycle, rod 52 is moved axially, disc 56 is rotated about spindle 40, and a pawl slides over one tooth of a ratchet wheel 63 fixed to spindle 40. When the further magnet is de-energized, rod 52 is returned by a spring, disc 56 returns to the position shown under the influence of another spring and the pawl engaging ratchet 63 rotates spindle 40 to lower carriage 38.

Title: Transistor bistable latch circuits

Filed: 1954-12-24
Abstract: 765,381. Transistor two stable state circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. , Dec. 24, 1954 [Dec. 31, 1953], No. 37378/54. Class 40(6) The input is applied between the emitter 1e, and a rectifying base 1b, the output being taken between the collector 1c and the base 1b with a feedback path between the collector and emitter. The feedback path may be'regarded as including an OR circuit consisting of diodes 9, 15 followed by and AND circuit of diodes 10, 13 so that the whole operates as a latching circuit. In the off state shown the emitter is held slightly negative by current flowing through resistors 7, 11 diode 10 and resistor 16, the junctions 14, 18 being held at the potential of battery 8b due to diodes 9, 10 conducting. Diode 13 is thus biased to its non-conducting condition. Operation of switch 8c raises the potentials of junctions 14, 18 and thus the emitter potential, the transistor conducting to pass appreciable collector current. The rise in collector potential is fed over diode 15 to maintain junction 14 positive so that reversal of switch 8c is ineffective. The circuit may only be reset by operation of switch 12c which causes diode 13 to conduct, thereby lowering the emitter potential sufficiently for the transistor to cut-off, the fall in collector potential being fed back over diode 15 to maintain the transistor in this condition the restoration of switch 12c being ineffective. Regarded as an OR and AND circuit, junction 14 becomes more positive when either switch 8c is operated or the collector potential rises. Junction 18 is held negative and goes more positive only when both junction 14 and switch 12c are in their more positive conditions to cause the emitter potential to rise and the transistor to conduct. U.S.A. Specification 2,609,428 is referred to.
