Title: Improvements in d.c. to a.c. inverters
IPC: H02M7/525
Filed: 1966-09-16
Abstract: 1,148,439. Automatic voltage control. STANDARD TELEPHONES & CABLES Ltd. Sept.16, 1966 [Sept. 21, 1965], No. 41409/66. Heading G3R. [Also in Division H2] In a bridge type inverter the A. C. output is used to control the overlap but not the duration of the conductive periods of the arms of the bridge so as to control the A. C. output. The bridge shown comprises four S. C. Rs connected by tapped commutating inductors and diodes connected to windings of the output transformer to prevent the potential at the ends of the transformer windings from swinging beyond the supply potentials. The control circuit includes an oscillator 7, each pulse from which sets a bi-stable circuit 9. This removes a diode clamp from a timing circuit 6 which, after the time delay, produces a pulse which resets bi-stable circuit 9. Negative output pulse transitions from circuit 9 change over a bi-stable circuit 13 and the output of this circuit correspondingly changes over a further bi-stable circuit 13 at the next input to its trigger terminal T. The outputs from the bi-stables 12, 13 control gates 15-18 which pass H. F firing signals to the S. C. Rs as described in Specification 1, 097, 891. The delay produced by the circuit 6 and thus the period during which conductor of opposite arms coincides is controlled by comparing at 4 the output from the inverter switch reference voltage from a Zener diode 3 and controlling the timing circuit accordingly.

Abstract: 1402463 Continuous casting VEREINIGTE OSTERREICHISCHE EISENUND STAHLWERKE AG 19 Sept 1972 [20 Sept 1971] 43366/72 Heading B3F A easing 10 below a (copper) mould 1 defines a cavity 15, facing the cast steel strand 2 withdrawn from the mould, to receive molten metal which may break out of the portion 4<SP>1</SP> of the strand shell 4 at the location and containing means such as a wire 16 for detecting the presence of molten metal. The wire 16 forms part of an alarm system which may operate to switch off the withdrawal drive. The molten metal destroys insulation on the wire 16 to establish an electric circuit involving the mould 1 or casing 10. Alternatively, an element or pyrometer responsive to temperature or light difference may respond to the molten metal to cause switching off of the withdrawal drive. To cool the strand shell portion 4<SP>1</SP>, a non-oxidizing gas may be passed through the cavity 15. A ring 11 mounts the casing 10 releasably on the oscillated mould 1, to which a bracket 8 bearing upper guide rollers 5 is fixed. The casing includes a cooling water jacket 12 and has at least a lower surface 14 for supporting the strand shell 4 and which may be provided by a separate copper section (28). There may be a discharge channel (30) from the casing, for the liquid steel. The casing 10 may be in separate parts (e.g. two parts covering merely the two broad sides of a cast slab), two opposed parts being relatively displaceable to accommodate different strand sections.

Means for cutting wire wound on a reel to enable it to be removed, comprises an adjustable support for the reel, a cutter carried by a spring-loaded plunger above the reel support, motordriven means for applying repeated impacts to the plunger when it is displaced against its spring, and means for raising the reel support to bring the wire on a reel into contact with the cutter in order to displace the plunger. The device comprises a column 1, a motor and housing 7, a rotor 8 and a tube 9 containing a spring- loaded plunger 10 which carries a cutter 11. A bracket 2 slides on the column 1 and carries a reel support 4 which can be raised, to a position determined by an adjustable stop-nut, by a hand wheel 6. Above the tube 9 is a collar 16 attached to a lever 17 which is mounted on a rubber bush 17 and which can be positioned by an adjustment screw 20. Within the collar is a ball 21 which rests on top of the plunger 10. In the rotor 8 are pockets 22 which contains balls or rollers 23. When a reel 5 with wire on it is placed under the cutter, the plunger is raised sufficiently to be struck by the balls or rollers 23 as the rotor turns, and so force the cutter into the wire.

Addition to 393,695. [Class 97 (iii)] The instrument described in the parent Specification is modified to obtain a directional gyroscope adapted to supplement magnetic compasses onair-craft. The modified instrument has a substantially horizontal spinning axis, a horizontal oscillation axis at right angles thereto, and a vertical turning axis, the erecting torque being produced by unbalanced air blast reactions acting around the vertical axis at opposed ports, situated in an axial extension of the rotor casing and controlled by gravity-controlled shutters pivoted adjacent to the ports. In the form shown in Fig. 3 the gyroscope rotor 12 is driven by compressed air from jets 10, 11, the used air issuing through laterally-disposed ports 15 controlled by pivoted shutters 17. Setting- means for the gyroscope comprises a setting knob 20, shown in Fig. 5, which is pushed inwardly to lift a slidable sleeve 23 on which rests a pin 24 attached to a pivoted lever 25 for locking the gyroscope about its horizontal axis ; a crown gear 21 on the shaft 51 is also engaged with the large gear 22 on the vertical ring of the gyroscope, which can be rotated to set it by turning the knob 20. The gyroscope may also be electrically run, the rotation of the rotor supplying air pressure for the differential air ports.

Abstract: 922,138. Electromagnetic powder-clutches. EATON MANUFACTURING CO. Dec. 22, 1960 [March 28, 1960], No. 44114/60. Class 35. [Also in Group XXIV] In a dual-unit, magnetic powder clutch in which parasitic torque in the inoperative clutch due to flux-leakage from the operative one is removed by a small reverse current in the inoperative clutch coil, transient parasitic torque produced during switching operations is eliminated by making the time constant of the two coils of the clutches equal, so that the currents build up in the two coils in constant ratio. The leakage flux 39 from the live coil 3, of the clutch is overcome in the steady-state condition by partially energizing the deenergized coil 5 to buck this flux. In the energizing circuit shown in Fig. 3, the same time constant for the two coils 3, 5 is achieved by always energizing them in series, the control switch 41 serving to connect a diverter resistance 55 in shunt, with whichever is required to be inactive. In different arrangements, equality of the time constants is preserved by using tapped coils with series-connected sections.

A cylindrical enclosure 81 with a pipe 82 for connection to a vacuum pump has a tubular extension 83 housing a lens assembly with a window or mass-defining slit of width equal to that of the target. Target holder 87 is secured to a lead screw 84 driven by a motor 85 controlled by a programmer 86. Rotation of the target holder is prevented by a torque resisting tube 88, but it is free to slide up and down as indicated by arrow B. The holder supports a plurality of racks filled with wafers 89. After implantation of one row of wafers the holder is indexed one step by fingers 92 and 93 engaging cam surfaces 94 and 95 fixed to the enclosure 81.
