Abstract: 967,737. Vacuum switches; contact members for switches. ENGLISH ELECTRIC CO. Ltd. July 11, 1961 [Aug. 23, 1960], No. 29048/60. Heading H2B. A vacuum switch has two electrodes 11, 12 providing cylindrical surfaces 11a, 12a facing one another, and means (not shown) for creating a magnetic field to rotate an arc set up between the surfaces. In Fig. 1 the electrodes 11, 12 are the contacts of the switch, the inner contact 11 being fixed and the outer contact being mounted on bellows 13 and movable into a position in which the surfaces are concentric to open the switch. Alternatively the outer contact may be fixed and the inner contact movable. Fig. 3 shows an arrangement in which the electrodes 15, 16 are concentric and fixed, a movable bridging rod 17 completing the circuit between the electrodes when the switch is closed. The cylindrical surfaces 15b, 16b may be of a material having a lower arcing voltage than the material of the arcing surfaces of the rod and the co-operating region on the electrode 15. The magnetic field applied in the direction F may be provided by a coil energized by alternating or direct current, or by a permanent magnet system.

[Class 39 (i)] A valve for short-wave use comprises a hollow body which determines the frequency of the arrangement and prevents the escape of stray radiation, and the metallic walls of the body are rendered gas-tight by glass elements fused to metal members of the valve. In one form, Fig. la, the hollow body comprises metal tubes A, B having end discs P, Q mounted on them. A filament K is axially stretched between cylinders C having discs E mounted on them, and the structure is hermetically sealed by annular glass beads S. The cylinder B has a central grid portion G consisting of longitudinal bars.

Abstract: 1506527 Motor vehicle suspensions CHRYSLER UNITED KINGDOM Ltd 14 July 1975 [12 July 1974] 29504/75 Heading B7D In a strut-type suspension for a steerable wheel 1 of a motor vehicle, the upper end of a suspension strut 3 is connected to a vehicle body 4 by a resilient mounting 5 which is arranged to be sufficiently yielding under lateral forces acting thereon to allow changes in vertical forces at the wheel 1 to produce changes in camber angle so that tendencies to wheel skimming resulting from the wheel 1 being out of round or unbalanced or due to the wheel rolling over a hump can be fully counteracted by gyroscopic forces resulting from the changes in the camber of the wheel. The resilient mounting 5 includes a rubber ring 51 which is bonded to support plates 57, 58 fixed to the strut 3 and body 4 respectively and has a wall thickness smaller than its height. Stops 54, 55 are arranged to co-operate with the rubber ring 51 to limit lateral deflection of the upper end of the strut. The rubber ring 51 is aligned so that its central axis A passes through the intersection of the midplane B of the wheel 1 and the axis C of a control arm 2 connected to the lower end of the strut. The invention may be applied to a double wishbone suspension.

Abstract: 435,296. Machinery guards. NIGHTINGALE, T., 94, Claremont Road, Pendleton, Salford, Lancashire. Oct. 17, 1934, No. 29650. [Class 80 (iv)] A guard gate A is mounted on a shaft B to. which is secured a safety finger D adapted to move with the guard and coact with a cam plate E carried by a control rod C adapted to actuate a belt fork c or a clutch. A latch F may be provided to engage, by its shoulder f, the lever D so as to prevent the guard from being raised whilst the machine is running. If the latch be not provided, raising the guard rotates lever D which, in turn, presses against cam plate E to move rod C and stop the machine. The latch, pivoted to a bracket G, rests on a pin e<1> projecting from the cam plate. Movement of rod C to the right to shift a belt from a fast pulley K, to a loose pulley K<1>, raises the latch F and permits the guard to be raised. A second latch H is provided having a shoulder h to engage the pin e<1> and prevent movement of the rod C to start the machine until the lever D is vertical and therefore the guard in the horizontal or operative position. The guard, which may have a balance weight W, may be additionally held in the operative position by latches engaging projections at the free end of the guard, Fig. 1 (not shown).

Abstract: 161,619. Western Electric Co., Ltd., (Assignees of Western Electric Co., Inc.) Nov. 28, 1919. Grids; wirework; electric fittings.-A grid, Fig. 3, for thermionic valves and like apparatus comprises a pair of U-shaped rods 11 to which wires 9 extending perpendicularly between corresponding limbs of the rods are fastened. In making such a grid, the rods 11 are laid in grooves on the top plate 1 and continued around the lower plate 2 of a frame, Fig. 1, and held in position by twisting their ends or otherwise; the plates 1, 2 have notches at the edges over which the wire 9 is wound by hand or by means of a lathe so as to cross the rods 11 everywhere at right-angles. The wire is then welded to the rods except in the middle where the rods are to be bent and the wire is cut at the edges by a pair of scissors inserted in grooves 12 between the upper and lower plates. The rods 11 are also cut at the ends of the frame. Reinforcing wires 34, 35 may be welded to the rods 11 if the cross-wires 9 are thin. The grids are bent in a machine, Fig. 6, comprising a base 14 having a recess in which is housed a block 21 guided by pins 24 and supported by springs 22<1>, 23<1>. To the block 21 are pivoted flaps 22, 23 which normally rest flat on the base. The grid is placed over these flaps and the block 21 is then depressed by means of a plunger-head 20 actuated by a handle 18 against the action of a spring 19; the flaps slide over the rounded edges 26, 27 of the recess and rise into a vertical position, thus bending the grid. The free ends of the two limbs of each rod may be welded together.
