Title: Printing control arrangement
IPC: B41J21/17
Filed: 1973-12-21
Abstract: 1443050 Automatic control of printing CASIO COMPUTER CO Ltd 21 Dec 1973 [25 Dec 1972] 59607/73 Heading G3N An electronic tab-setting arrangement for a typewriter includes a register storing a number of tab-set positions, and a counter which is stepped in synchronism with the typewriter mechanism. When a head tab-set position is reached, a corresponding control signal causes return movement of the printing head to stop. As shown, a left hand margin determining head tab-set position is supplied through an AND circuit 19 to a shift register 11 synchronized by clockpulses from a generator 14 with a second register 13 which stores digital information indicative of the position of printing head 18. When a head return instruction is supplied through OR gate 24 and flip-flop 25 to the head motor control circuit 15, an AND gate 23 is enabled so that coincidence between the registers 11, 13 produces an output signal through OR gate 26 to reset flip-flop 25 and stop the head motor in the head tab-set position. The arrangement also controls the right hand printing margin, in that a circuit comprising a flipflop 28 and delay circuits 27, 29 responds to coincidence between register 13 and a last tab-set position stored in register 11 to produce a signal which sets flip-flop 25 through OR gate 24, causing the control circuit 15 to initiate the return movement of the printing head. An alternative shifting arrangement is also described, Fig. 4 (not shown), using a variable length register.

IPC: H02M1/088
Filed: 1970-12-23
Abstract: 1337596 Converting GENERAL ELECTRIC CO 23 Dec 1970 [29 Dec 1969] 61274/70 Heading H2F In or for a HVDC transmission system, a switching circuit comprises a series arrangement of thyristors 41 . . . 44 and a first saturable-core inductor L1 which is bridged by a circuit comprising resistors R1, 61 and a second saturablecore inductor L2, part of the series circuit being bridged by a non-linear shunting path, e.g. diodes 57, 58. Much of the subject matter is the same as that described in Specification 1,217,894 in which inductor L2 is linear. The use of a saturable-core inductor L2 enables a smaller inductor L1 to be employed. L2 is arranged to saturate before L1, resistors R1, 61 being such that the circuit comprising L1 and the line capacitance is underdamped so that after a peak of oscillation, diodes 57, 58 become conductive, shunting L2 and 61, so that the circuit is now overdamped by resistors R1. Further saturable core-inductors L4 are included together with capacitor C4 so that in the event of excess voltage, thyristor 43 becomes conductive due to V BO  break-down, L4 preventing turn-on of the other thyristors in their di/dt mode but allowing them to turn on in their dv/dt mode, C4 preventing turn-on in the V BO  mode. Alternatively thyristors having differing V BO  charac teristics may be selected.

Abstract: 705,336. Snap-action retractive switch; snapaction thermal switches. BRITISH THOMSONHOUSTON CO., Ltd. Jan. 8, 1952 [Jan. 10, 1951], No. 582/52. Class 38(5) A snap-action switch has a blade spring 3 with a re-entrant central arm 3a and a pair of side arms with inturned ends held in inclined relationship with reference to the central arm so as to impart to the blade a dished formation and angularly displace the central arm from the normal plane of the blade. In Fig. 1, the central arm has a contact 4 which is normally in engagement with a fixed contact 2 and a push rod 6 engages the side arms. On movement of the push rod to the left, manually or by thermally responsive means, the blade reverses its curvature with a snap-action and the contacts are opened. The side arms 3 are mounted on a U- shaped bracket 5, Fig. 3, with an adjusting screw 7, which may be used to alter the spacing of the ends of the side arms so as to alter the internal stress of the blade. The cross-sectional area of the-blade is reduced in the regions BB and this is stated to assist in ensuring that contact pressure is maintained until the snap-action movement has irreversibly started. In Fig. 6 (not shown) the blade is bimetallic and reverses its curvature on heating by a heater coil. Figs. 7 to 9 (not shown) illustrate modified forms of the blade spring. Specifications 600,055 and 622,781 are referred to.
