Title: Improvements in and relating to electric discharge vessels made of ceramic material and to a process for the production thereof
IPC: H01J5/26
Filed: 1936-11-09
Abstract: 467,720. Discharge apparatus. SHEVLIN, J. T. (Siemens & Halske Akt.-Ges.) Nov. 9, 1936, No. 30514. [Class 39 (i)] [Also in Group XXXVI] A ceramic envelope is provided with small openings for the leads and one or more larger openings for the electrodes, and the openings are sealed up by soldering. The ceramic parts may be metallized by applying a metal, e.g. iron, powder and heating in vacuo to sinter the layer to the base at a temperature of from 126‹ to 127‹ C. The soldering is effected by using silver solder in a hydrogen furnace, or the two steps may be performed in a single furnace. Diffusion resistances may be employed to keep a mercury vapour filling from the joint and the metal surface may be carbon-coated to prevent solder adhering where vapour may be present. The ceramic materials known under the Registered Trade Mark " Calit " or the names " calan " and " ultra-calan " may be used. In one form, Fig. 1, a ceramic envelope 1 has apertures 2, 3 for the anode leads, 4 for the pumping tube and 5 for the receptacle 6 of the mercury cathode 13. The caps 6, 7, 8, 9 are soldered over the openings, the anodes 11 being introduced at 5. Mercury is inserted through the tube 9 and after pumping this tube is sealed by hard solder 14. In a modification, a thermionic cathode and the anodes are introduced through a side-hole subsequently closed, and the cathode is mounted on leads passing through apertures similar to 2 and 3. The apertures may be closed by soldering-on metallized ceramic caps. The anodes may be replaced by a single anode plate closing the large aperture, or three such anodes, together with a cathode mounted on smaller plates, may be employed, Fig. 4 (not shown). The supply leads may be connected to bayonet pins on the envelope. The anode plates may be convex to the interior and metal screen members or coatings may protect the ceramic wall ; a cooling jacket may then be slipped over the device. In another modification, the anodes are corrugated or provided with cooling fins. As shown in Fig. 9, a control-grid 15 may be arranged between the cathode 2 and the anodes 7,8.

Filed: 1923-12-06
Abstract: 230,180. Guadagni, G. Dec. 6, 1923. Feeding in definite proportions.- Apparatus for the manufacture of acids and particularly suitable for the production of nitric acid when the latter is for use in the chamber process of making sulphuric acid comprises means operatively connected together for feeding nitrate of soda and sulphuric acid to a, reaction chamber and an outlet pipe for the discharge of the residual sodium bisulphate of such a cross-section that the reaction is completely finished and all nitrogen oxides expelled' before the mass is discharged. In one form, Figs. 1 and 2, the nitrate is fed by a screw conveyer 5 to a cast-iron reaction chamber 6 which also receives sulphuric acid fed by means of a tiltable scoop 20 operated by a. rocking lever 16 driven from a worm-wheel 8 on the shaft of the screw-conveyer. The scoop 20 dips into a constant level tank 21 and when the spout 22 strikes a projection 23 on the edge of the tank its contents is discharged. The quantity of acid delivered is regulated to suit the rate at which the nitrate is fed by raising or lowering the rod 30 by means of which the rocking lever is supported. In another form, Fins. 3 and 5, more particularly intended for the manufacture of hydrochloric acid, sodium chloride is fed by a bladed distributor 41 to a reaction pot 6 set in a furnace. During the same time an equivalent quantity of sulphuric acid is passed to the pot 6 from tanks 42, 43 by means of siphons 46, 47, which are alternately operated from the shaft of the distributor 41. A crank-pin 14 on a worm wheel 8 imparts, by means of a rod 44 a to and fro movement to a rod 45 which causes the siphons 46, 47 to be alternately raised and lowered by rods 48, 49. The rod 45 also causes the jet of acid issuing from the flexible supply pipe 61 to oscillate over the tanks 42, 43 through the intermediary of stops 56, 57 and the pivoted lever 58. By raising or lowering the blocks 64 the capacity of the tanks is regulated.

Abstract: 1370542 Moulding tyres RUBBERFABRIEK VREDESTEIN NV 30 June 1972 [10 July 1971] 30743/72 Heading B5A A preheating chamber 60 for a radial or crossply green tyre blank 47 (116, Fig. 3) is subdivided by walls 64-69, 84-89 (119, 120, 123-126, Fig. 3) into compartments so that each compartment may be served by a size of heat source 72-76 (130, 131, Fig. 3) appropriate to the thickness of the part of the tyre blank embraced by the compartment. This ensures that parts of different thicknesses of the tyre are brought to different temperatures prior to being placed in the press so that upon being placed in the heated vulcanizing press all parts of the tyre blank reach the same temperature at the same time to produce a uniform degree of vulcanization throughout the tyre. The tyre blank is gripped and rotated relative to the heat sources by upper and lower disc shaped clamps 41, 12 (109, 103, Fig. 3). The lower clamp which is driven by a V-belt 10 and electric motor 8 drives the upper clamp via friction layers 13, 49 connected to the respective clamps. The upper friction layer may be on the upper clamp itself (113, Fig. 3) or on a shaft 48 connected thereto. The upper clamp 41 is rotatably mounted on a thrust rod 35 which can be actuated by a piston 38 to raise and lower the clamp 81 for loading and unloading of the tyre blank. To assist loading, the clamp 41 can be pivoted by a rod 27 acting on a pivotal bush 22 accommodating the rod 35. The shaft 48 may carry adjustable discs 50, 53 to subdivide the chamber 60 inward of the tyre blank. The disc clamps 41, 12 include grooves 42, 14 or shoulders (115, Fig. 3) for receiving the edges of the tyre blank. The grooves in the upper clamp may include a double hose for gripping a marginal bead 46 of the tyre. The bead may include a steel wire inlay and may not be preheated. Steel wire heat seals 44, 19 may be provided between the clamps and chamber 60. The latter may comprise hinged hemi-cylindrical halves 61, 62. Impellers 90 (132, 133, Fig. 3) may be provided for wiping the discharges of the heat sources 72-76. The latter may be fed from a respective or common source of micro-wave energy. Apparatus parts subject to impingement of micro-wave energy may have a coating of (e.g. 18, Fig. 1) or be made of (e.g., impellor 90) brass.
