Filed: 1945-05-04
Abstract: 594,424. Vehicle stands. MOTTERSHAW, H. B. May 4, 1945, No. 11322. [Class 79. (iii)] In a road vehicle jack of the type comprising a lever pivoted to the vehicle, which lever is adapted to be turned into operative position by a projection on the road wheel which then moves clear of the lever, and is turned into its inoperatives position by a projection which then clears the lever, the projection on the wheel is adjustable so that it can be moved into either of the two positions. The lever 1 pivoted at 1a is normally held clear of the ground, but by inserting a pin 8 with an offset projection 9 in one of the holes 6 in lugs 5 secured to the wheel, and moving the vehicle, the projection 9 engages the lug 4 on the lever 1 and move the lever into jacking position, as shown in full lines in Fig. 1, resting against the stop 15a. When this position is reached, the projection 9 moves clear of the lug 4. To restore the lever 1 to its inoperative position, the pin 8 is withdrawn, turned through 180 degrees and reinserted, whereby the projection 9 will again engage the lug 4 and reverse movement of the vehicle will return the lever 1.

Fuel elements are supported one on another in a nuclear reactor fuel channel by faces of their end plugs, and are axially aligned by means of annular rings attached to the fuel element end plugs and having successively semi-torroidal outer surfaces and frustro-conical inner surfaces. The adjacent ends of two fuel elements 1, 5 within a fuel channel A each have fins 2<SP>1</SP>, 5<SP>1</SP> and welded end plugs 3, 6, abutting at 7. The ring shaped centring members 12 are screwed on to the end plugs and have respectively an integral semi-torroidal male member 10 and an integral frustroconical female member 11. The tolerance allowable on axial alignment determines the clearance allowable between the male and female centring members, but it is important that some clearance exists in order to ensure that, in the case of vertical channel, the load is supported by the faces of the end plugs directly, and not by the centring members. In the embodiment shown, the centring members are locked by abutment of the ring portions with the bottoms of the grooves 8, but in a modification locking may be effected by a flange on the centring member abutting the terminal shoulder of the screw thread 9.

Title: Improvements in or relating to physico-chemical processes performed on semiconductormaterials or devices
IPC: C30B31/10
Filed: 1962-03-29
Abstract: 993,261. Semi-conductor treatment. COMPAGNIE FRANCAISE THOMSON-HOUSTON. March 29, 1962, [March 29, 1961,] No. 12110/62. Drawings to Specification. Heading H1K. In manufacturing semi-conductor devices which are treated in a sealed quartz jacket taken to a high temperature, the outer surface of the jacket is covered, either wholly or in its hottest zones, by a layer of liquid at the operational temperature produced by the action of a solvent on the quartz of the jacket. Such a solvent may be, for example, a mixture of sodium silicate and one or more oxides of bivalent metals such as lead, magnesium, and barium; boric acid optionally containing borosilicate glass; or sodium oxide. The liquid/solid system of the jacket surface acts as a barrier to vaporized impurities (such as iron, copper, and nickel) produced in the furnace and to which untreated quartz is permeable at high temperatures. An automatic method of applying the solvent consists of surrounding the jacket with a muffle made from a refractory material such as alumina containing a small proportion of solvent which is volatile at the temperature of the furnace, for example sodium oxide. In the embodiment described with reference to Fig. 1 (not shown) silicon wafers are to be in diffused with gallium. The process takes place in a silica glass (clear quartz) jacket completely coated with a sodium silicate (lead oxide mixture initially applied as a suspension of the oxide in an aqueous solution of the silicate. The jacket is placed within an opaque quartz muffle lying along the axis of a furnace, the two regions of which may be kept at different temperatures so the temperature of the gallium source may be different from that of the silicone wafers. A similar liquid-coated quartz tube may be used for the purification of gallium arsenide.

Abstract: 142,808. Gnudi, A. May 3, 1920. No Patent granted (Sealing fee not paid). Controlling variable-speed gearing.-Separatelymovable striking-forks 24 - - 24<IV>, Figs. 2 and 6, are selectively secured to a sliding rail 15, Fig. 4, by a push-button device 60, Fig. 11, the rail 15 being operated by the main clutch pedal 48, Fig. 2. In the boss of each fork 24, Fig. 6, is a spigot 25 normally pressed by a spring 26 into engagement with a hole 28 in a fixed locking-plate 27. The rail 15 slides in a fixed guide-block 8, Fig. 2, which guides the forks 24 also. Push-buttons 61 - - 61<III>, Fig. 11, act through mechanical, electric, pneumatic, or other means to impart a displacement of different amounts to a sliding ledge 34, which carries spring-pressed pins 36 - - 36<IV> directed downwards in the plane of the. spigots 25 - - 25<IV>. The selective control brings one pin 36 over one spigot 25, so that a downward movement of the ledge 34 causes the spigot to disengage the plate 27 and engage one of a number of recesses 16 - - 16<IV> in the rail 15. The lever 48, Fig. 2, is connected through a cam 41 and rod 37 to a block 38 so arranged that after the clutch has been operated, the block 38 is moved. When the ledge 34 is moved to make a selection, an incline 35 upon it thrusts downwards a plunger 49 carried by the rail 15 into engagement with the block 38, so that the rail 15 is then moved by the lever 48. The ledge slides in a guide 29, which has a depending arm 29<1> sliding in a hole in the guide-block 8. The arm 29<1> carries a cam 32 engaged by a bowl 22 upon the rail 15. Sliding movement of the rail 15 through the bowl 22 and cam 32 brings down the ledge 34 to cause the engagement of the fork 24 selected with the rail 15 as before described. Return movement of the lever 48 then causes the rail 15 to return, carrying with it the selected fork, so as to bring the speed required into operation. Projections 17 - - 17<IV> upon the rail 15 are adapted on the first movement of the rail to engage and return to neutral position any fork previously in action. The rail 15 is locked by spring-pressed balls 50. Specification 14403/15 is referred to.
