Title: Improvements in Interlock Devices
IPC: H01H9/26
Filed: 1967-07-31
Abstract: 1,199,074. Interlocking switches. WATFORD ELECTRIC CO. Ltd., and W. A. J. SAUNDERS. 22 July, 1968 [31 July, 1967], No. 35126/67. Heading H1N An interlock mechanism to prevent closure of an isolating switch while a contactor is closed comprises a plate 4 pivoted at 7 to a support 10 and carrying a latch arm 1 also pivoted at 7. Plate 4 is urged anticlockwise by a spring 8 while arm 1 is urged clockwise, against a stop 11  on plate 4, by a spring 5. The end of arm 1 extends into an L-shaped slot 12 in a plate 2 which is coupled to the isolating switch to slide on pillars 6 secured to support 10. A rod 3, having a chamfered nose, is moved perpendicularly to the plane of the drawing by operation of the contactor. As shown, the plate 2 is at its right-hand limit corresponding to the closed condition of the isolating switch, and the portion 12a of slot 12 is holding arm 1, and hence plate 4, against the action of spring 8. When the contactor is closed the rod 3 moves freely to project below plate 4 (Figs. 1 and 2, not shown). If the isolating switch is then opened plate 2 moves to the left but rod 3 prevents plate 4 from rotating; hence arm 1 rides up the sloping portion 12a of slot 12 against the action of spring 5 which latches it into the vertical portion of slot 12 (Fig. 1, not shown). The isolating switch cannot then be moved to the closed position until the contactor is opened, withdrawing rod 3 to allow plate 4 to rotate under action of its spring 8 and thus lift arm 1 to unlatch plate 2. If the isolating switch is open (plate 2 to the left) when the contactor closes the nose of rod 3 lifts plate 4 against its spring 8 and moves arm 1 into the latching position so that the isolating switch again cannot be closed until the contactor is first opened. A spring 9 assists movement of plate 2 to the left (switch-open) position. Reference has been directed by the Comptroller to Specifications 1,061,890, 1,069,551 and 1,138,963.

In a carburetter with two separate passages 4b, 5b, supplying respectively either air and fuel air mixture or mixtures of different strengths, a fuel metering orifice 62 is controlled by metering means 64 operated by a piston 16 responsive to pressure downstream of the throttle valve 7, the orifice 62 being increased as the aforesaid pressure decreases. The fuel from orifice 62 flows through passage 52 to the main nozzle 57 in the passage 5b, the passage 4b supplying pure air. A second metering orifice 12 is controlled by a needle 30 operated by a lever 26 connected to the throttle operating lever 17 which is connected to the linkage 10 of the throttle valves 6, 7, through a spring 24. Up to wide throttle opening lever 26 is inoperative. Movement of lever 17 beyond the wide throttle position causes lever 26 to contact rod 28 and lift needle 30 to enrich the mixture. Alternatively lever 26 can operate needle 30 when throttle 7 nears wide open position. In Fig. 5 (not shown) needle 30 is omitted and the needle 64 is subjected both to the suction operation and to the action of the rod 28 through connection 72. In Fig. 6 both carburetter passages are supplied with fuel the suction operated needle 15 being associated with one fuel nozzle 58 and the maximum throttle needle 13a being associated with the other nozzle 57a.

Title: Improvements in electric switches with arc-extinction by selfgenerated vapour
IPC: H01H33/75
Filed: 1931-12-24
Abstract: 384,819. Arc-rupturing in hightension switches. RUPPEL, S., 8, Palmengartenstrasse, Frankfort - on - Main, Germany. Dec. 24, 1931, No. 35749. Convention date, Dec. 24, 1930. [Class 38 (v).] In a switch in which the arc is extinguished by the sudden expansion and condensation of vapour generated by the arc, the passage connecting the liquid chamber with a closed expansion chamber is substantially equal to the maximum cross section of the liquid chamber. In Fig. 1, a movable contact 1 extends through a piston 4 of insulating material which fits and slides in a liquid chamber 9. A gauge 10, from the bottom of which sludge may be tapped, connects the chamber 9 with an expansion chamber 6 and some .liquid is initially forced through it from the liquid chamber to the expansion chamber by the pressure, produced by the arc, which liquid assists the condensation in the chamber 6. After the switch has operated the liquid returns to the liquid chamber. An air-break switch 15, 17 is provided in series with the liquid switch. In Fig. 2, the movable contact 1 carries a piston 37 formed as a seal for the expansion chamber 6, the piston sliding in a guide tube 38, so that the volume of the expansion chamber increases as the switch opens. In Fig. 3 (not shown), a piston acts as a liquid chamber, and cooling ribs are provided for the expansion chamber. In another arrangement, two sets of contacts are provided in series, and springs are arranged to ensure correct operating sequence. In this case the contact rod may be entirely removed from the switch chamber since the hole through which it passes is covered by the piston in its raised position. In Fig. 5 (not shown), a concertina casing connects the expansion chamber with the contact rod, and assists a spring in ensuring correct switching sequence. The piston may be spring mounted on the switch rod so that the moment of expansion is influenced by the generated pressure, and a magnet energized by the switching current may be provided for accelerating the movement of the piston. The expansion chamber may be made of quartz or Jena glass. The liquid and expansion chambers may be resilient or may have plates covered with wire network adapted to fracture under excessive pressure.
