An electric discharge device for use in a gasdischarge switch, comprises a gas-filled envelope and a capacitative element formed by at least two cylindrical members 8, 12, Fig. 1, one of which is inside the other, the capacitative element also constituting a pair of electrodes between which the main discharge occurs in operation, the envelope including a tubular portion 10 provided at one end with a laterally projecting metal flange 5 which is in good electrical connection at least with respect to radio frequencies with one of the electrodes 12 and provided at its other end with a terminal 3 which is in good electrical connection at least with respect to radio frequencies with the other electrode 8, the terminal constituting a longitudinal extremity of the envelope and being shaped so as not to project laterally in any direction to a greater extent than the flange. The gas filling is preferable krypton at 20 mm. of mercury pressure. The tubular portion 10 may also perform the function of an electrode. In a preferred arrangement of a T-R switch, Fig. 2, two such discharge tubes 1 are located on opposed side of a central conductor 15, 17 of a two line transmission line, the other conductor 14 being cylindrical and adapted to support the flanges of the two discharge tubes. An inductive stub 30 is also provided and with the capacitive element which has a value of about 10 ÁÁF, a resonant system having a resonant frequency of 200 mc/s. is formed, and has a loaded Q of approximately unity. The R.F. currents induce the discharge in the tubes, and the delay time may be reduced by appropriate biasing potentials applied to the electrodes. The metal ports of the discharge tube may be formed of an alloy of 54% iron, 29% nickel and 17% cobalt. In an alternative construction, the inner electrode may be formed of a circular cylindrical block of porous refractory metal impregnated with alkaline earth metal compounds, the spacing between the electrodes may then be reduced to 1 mm., the activated electrode inhibiting spattering which otherwise would produce a short circuit between the electrodes. According to the Provisional Specification, the device may have a filling of Xenon at 2.5 mm. of mercury partial pressure and water vapour at 0.5 mm. of mercury partial pressure and there may be provided a water vapour replenisher of the type described in Specification 805,944.

Mechanism for tipping dust bins into refuse vehicles comprises a lifting lever and a guide lever, attached to each of a pair of power-operated swing levers to guide the movement of a basket holding the bin. A pair of lifting levers 3, poweroperated by a piston 22 of an hydraulic or pneumatic ram 23 has a bin receiving basket 10 pivotally mounted thereon by lifting levers 6 and guide levers 7 pivoted on each lever 3 and forming a four-point, preferably parallelogram, linkage. A telescopic strut 27, 28 extends between a fixed bracket 30 and a pivot-pin 26 on each lever 6. A plate 31 having a suitable opening for the dust bin is hingeably mounted on a shaft 2 and has behind it dust shields 34, 35. The shield 34 has a tooth 57 for cooperation with the yoke portion 58 of a grip on the bin lid 33. Initial movement of the levers 3 from the position of Fig. 1 to the intermediate position of Fig. 4 exerts a compressive force on the struts 27, 28, holding them fully closed and causing the levers 6, 7 to swing along the paths 60, 61 about the levers 3. On reaching the intermediate position, Fig. 4, the coupling tooth 57 engages the yoke 58 and the plate 31 with its dust shields 34, 35 become entrained with the movement of the basket 10. The telescopic struts 27, 28 are now subjected to tension and extend holding the levers 3, 6, 7 in the same relative position during the final movement of the levers 3. As the final position is approached with the plate 31 on buffers 42, the dust shields 34, 35 and attached lid 33 swing to open the latter and a locking device 43 operates to secure the basket 10 to the plate 31 until the position on the return movement at which the parts 33-35 drop back under gravity.
