G. ; 306, Cooper Street, Camden, New Jersey, U.S.A.) Dec. 21, 1934, No. 36662. Convention date, Dec. 21, 1933. [Classes 39 (i) and 40 (v)] An electronic-period oscillator of the magnetron or Barkhausen-Kurz types is provided with means for setting up an electrostatic field with a component in the direction of the axis of the electrodes. As shown in Figs. 1 and 3, a magnetron oscillator with a split cylindrical anode 7 arranged round an axial cathode 13 is provided with end-plates 21, 23 held at a positive potential relatively to the cathode. The electrostatic field within the anode is thus given an axial component as indicated by the full curved lines of Fig. 3, and the periodic movement of the electrons follows the dotted lines 31. The tube is placed in a magnetic field set up by coils 19 which may have a non-axial component. The end-plates 21, 23 are supported by conducting leads 25, 27, which pass out through the press 3 of the tube, and the anode sections are connected to parallel wires 9, 11 which pass through the opposite end of the tube to form a Lecher wire output circuit. The wires are bridged within the tube by a cross rod 6 placed at a voltage node, and this rod has an arm 10 fused into a glass bead 12 into which is also fused a rod 8 carried by the press 3. The external circuit, Fig. 4, comprises a D.C. source connected between the cathode 13 and the mid-point of a di-pole aerial 35 energized by the Lecher wires 9, 11. The endplates 21, 23 are given an adjustable positive voltage by a slider 45 on a potentiometer 41 across the D.C. source. Modulation voltage may be applied by a transformer in the lead 43, Fig. 9 (not shown). The end-plates may be separated from the cathode by small quartz cylinders, Fig. 7 (not shown). The anode plates 61 may be flared at their ends as shown in Fig. 6, whilst the end-plates 63 may be of conical shape. In another form of magnetron oscillator, Fig. 5, two cylindrical anodes 47, 51 each surrounding its own axial cathode are provided in the same tube 45, and the endplates 55 serve jointly for both anodes. The end-plates may be arranged across the open ends of the anode of a triode valve operating as a Barkhausen-Kurz oscillator, Fig. 8 (not shown).

A composite skid rail for use in pusher-type furnaces, comprises rail sections 1<SP>1</SP>, 21 and 31 constructed from materials selected to withstand the mechanical and heat stresses in different zones of the furnace, thereby avoiding the necessity for cooling the rail. Section 11 is made of heat-resisting steel, preferably nickelchrome steel, to withstand the considerable temperature changes in the preheating zone of the furnace, where the approximate temperature range is 20-600‹ C. It may comprise a steel plate 11 disposed on a refractory base. Section 21 is made of silicose carbide to resist sudden temperature changes and abrasion in the next furnace zone up to approximately 900‹ C. The final section 3<SP>1</SP> is disposed in the hottest part of the furnace, where the temperature is more uniform, but where the rail may be subject to the action of scale from the charge. This section is made of fused oxide mixtures, e.g. an aluminium silicate containing approximately 72- 75 per cent Al 2 O 3  and 20 per cent SiO 2 . The cross-section of the rail is preferably trapezoidal and may have rounded upper corners.

In the embodiment shown the sealing means comprise a flexible collar 24 and a flexible funnel 25. In another embodiment, Figs. 2 and 3 (not shown) the sealing is effected by pressing a metal flange (30) on the container 11 against a ring (29) of resilient material on the sprue.

[Also in Division F1] A metering button cap 1 for use in an aerosol type container, with a continuous flow valve having a hollow valve stem 2 comprises a cap body 20 having a chamber 21 closed by a cage 23 which is sealed with the stem by means of an 0-ring 24 and a member 27 forming, with the cap, a sub-chamber 30, the member having a sealing gasket 28 adapted to close the end of the stem in order to prevent flow through the stem and an outlet 22 in the cap. The stem 2 is slidable in gasket 10 secured in a collar 3 which is adapted to be attached to a pressurized container. In operation, upon depressing the cap, the sealing gasket 28, first closes the open end of the stem and, continued pressure then causes a port 9 in the stem to be uncovered thereby allowing the pressurized fluid to flow from the container into the chamber 30 via the stem. When the pressure on the cap is released, the port 9 is first closed and then the gasket 28 moves away from the stem thus allowing the fluid trapped within the stem and the chamber 30 to flow out of the discharge port 22. The cage 23 and the member 27 may both be replaced by ones of different size in order to vary the amount dispensed and to suit different sizes of stem.
