Title: Improvements in or relating to automatic control systems embodying servomotors
IPC: F15B9/08
Filed: 1941-08-08
Abstract: 551,170. Automatic-control systems. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MEREDITH, F. W. Aug. 8, 1941, No. 10122. [Class 135] An automatic control system, particularly an automatic pilot for aircraft, comprising a servomotor having a control device operated by a " control " influenced by fluctuating external condi ions and arranged to maintain a steady predetermined condition in the system is provided with means for cutting the automatic system into and out of operation and with means for applying a balancing control to the control device which at the instant of cutting in the system is equal but of oppositive sign to the first control and with means for gradually removing the balancing control after the automatic control system has been cut in. The Figure shows the invention applied to an automatic pilot somewhat similar to that described in Specification 534,527. The power device 30 is controlled by a control.valve 20 actuated by a pair of opposed bellows 11, 15. A variable pressure corresponding to the deviation is applied through a pipe 10 to the bellows 11. 'The bellows 15 is connected through a pipe 38 with a follow-up bellows 39 operated by the power device and through a pipe 47 with an auxiliary, chamber housing a bellows 48. When the automatic control is in operation the bellows 48 is subject to a constant datum pressure maintained by a relief valve 54 and transmitted through a change-over valve 33. When the automatic control is cut out by interrupting the supply of motive fluid through a pipe 22, pressure acting on the valve 33 is removed and spring 57 moves this valve to connect the bellows 48 to the pipe 10. Under these conditions equal pressures are maintained in the bellows 11, 15 and the control valve held in its neutral position. When the automatic control is cut in, the valve 33 returns to its former position putting the loading of the bellows 48 again under the control of the relief valve 54. The pressure in the bellows 15 is thus restored to its datum value, but such restoration only takes place slowly owing to the provision of a restriction in the conduit 47.

Title: Transistor switching circuit
IPC: H02M3/335
Filed: 1972-03-06
Abstract: 1387486 Transistor switching circuits INTERNATIONAL BUSINESS MACHINES CORP 6 March 1972 [30 April 1971] 10271/72 Heading H3T [Also in Divisions G3 and H2] A switching circuit comprises an inductive load such as a transformer 1 connected in series with a switching transistor 51 and a control transistor 54 actoss a D.C. supply 6, the control transistor 54 being driven by pulses while the base of the switching transistor 51 is biased via a path having a low impedance only in the reverse direction, so that when the control transistor 54 is non-conductive the switching transistor 51 is in its open-emitter condition. As described, during positive half-cycles of adjustable mark/space ratio from the control unit 52, transistors 51 and 54 are conductive so that current builds up in the primary 2 of transformer 1, inducing a voltage in winding 3 which is rectified at 23 to provide the required D.C. output at terminals 4, 5. On the negative halfcycles from the control unit 52, the control transistor 54 is made non-conductive, cutting off switching transistor 51 by opening its emitter circuit so that transistor 51 only experiences the collector/base breakdown voltage. The induced voltage in winding 2 is rectified by diodes 38, 39 and, if it exceeds the breakdown voltage of Zener diode 32, turns on transistors 30, 31 so as to damp the circuit. Diodes 55 ... 59 limit the saturation of switching transistor 51. Components 29, 27, 97, 99 suppress high frequency noise across rectifier 23 and free-wheeling diode 24. In Fig. 5 (not shown) the primary and secondary windings of transformer 1 are arranged in push-pull. In Fig. 6 (not shown) components 38 ... 43 are replaced by a diode, capacitor and discharge resistor. Parallel switching transistors are employed and a Darlington control circuit is used. In Fig. 4 (not shown), complementary transistors 51 and 54 are employed. The output may be regulated by comparison of input or output with a reference potential, the error voltage adjusting the width of pulses from control unit 52.

[Class 100 (iii)] Clamping matrices ; moulds.- In the means described in the parent Specification for casting type-bars with low surfaces or low-quad portions beyond the character-bearing portion by means of ribs or projections on the vice-jaws, the entry of the projections into the mould is facilitated by the provision of a movable mould-liner, which forms at least one of the longitudinal walls of the mould cavity, and is pushed back by the projections when the mould-disc moves forwards. The upper and lower mould sections 2, 3, Figs. 2 and 5, are spaced apart by a thin liner 6, Fig. 9, having spacing- blocks 7 at its ends. Beyond the ends of the liner, the mould sections are separated by fixed auxiliary spacers 30. The liner 6 is of slightly less width than the front-to-rear depth of the mould, and is free to slide transversely. The mould sections are movable towards and away from each other, and are clamped together during the casting by means such as that described in Specification 370,296, and comprising a vertically movable clamping- plate 15, which engages the upper mould section 2, and is operated through a lever by the movement of the metal-pot. 'The liner 6 normally stands with its front edge flush with the face of the mould, and is pushed back by the ribs 13<a> on the vice-jaws 13 as the mould moves forwards. As the ribs are of less height than the total vertical height of the mould, they can enter freely. The edges of the ribs are bevelled, and, if the liner forms only one of the longitudinal walls of the mould, the front edge of the lower mould section is correspondingly bevelled. The liner 6 is restored to normal position by the action of pins on the machine frame, which enter apertures in the auxiliary spacers 30 when the mould moves towards the trimming-knives, and act through rocking pawls on the liner.
