Abstract: 1,222,872. Recovery of molybdenum. ATLANTIC RICHFIELD CO. 29 May, 1968 [22 June, 1967], No.25838/68. Heading C1A. Molybdenum is recovered from organic solutions (resulting, for example, from organic reactions using a molybdenum compound as catalyst) by contacting the solution with an aqueous ammonium phosphate solution and recovering the precipitate ammonium phosphomolybdate. The concentration of the ammonium phosphate solution is preferably between 5 and 20% by wt. and is preferably added so that the mole ratio of ammonium phosphate to molybdenum in solution is between 0.8: 1 and 2.0: 1.

Title: Improvements in or relating to methods of forming p-n junctions in semiconductors
Inventor: JAMES EMRYS GWYNNE
IPC: H01L23/04
Filed: 1957-08-15
Abstract: 849,549. Semi-conductor devices. GENERAL ELECTRIC CO. Ltd. July 29, 1958 [Aug. 15, 1957], No. 25846/57. Class 37 A PN junction in a semi-conductor body is formed by heating a wire comprising significant impurity in contact with a semi-conductor body to form a molten alloy region and then cooling in a manner such that the region of the body adjacent the molten region cools faster than the portion of the wire adjacent this region. The process avoids discontinuities in the recrystallised region. Fig. 1 shows an interim stage in which an N-type silicon body 1 is supported by a carbon block 2. Initially, an aluminium wire 16 suspended from support 17 is lowered into contact with the body 1 on support 2 which is heated to 700 ‹C. by the passage of electric current. On contact, the current is switched off so that the wire and body alloy together. The body 1 with attached wire 16 is then inverted and placed in block 2 as shown in Fig. 1, the block 2 then being heated to 800 ‹C. for about six seconds. While nitrogen is passed from stem 12 to escape through hole 14. Wires 5 and 6 are associated with a thermo-couple for temperature measurement. The assembly is allowed to cool to form a PN junction, the wire being maintained throughout the cooling at a higher temperature than the body owing to the thermal capacity of the surrounding blocks 2. An ohmic connection to the body 1 is made by heating a gold-antimony wire 18 as it is lowered to contact body 1. The assembly is then etched, washed, mounted on two copper wires 25 and 26 (Figs. 2 and 3) in a copper envelope comprising two cup-shaped portions 20 and 21 which are cold welded together in an atmosphere of nitrogen. A drop of silicone resin is disposed on body 1 and wires 16 and 18. Specification 817,636 is referred to.

[Class 108 (iii)] A resilient suspension device comprises a leaf or thin plate spring 1, Fig. 1, in the form of an open ring, housed between internal and external supporting - surfaces 5 and 6 of such a shape that the spring finds support against an increasing portion of the internal and external surfaces respectively, as it is closed or opened. The supporting-surfaces are formed by the internal walls of U-shaped grooves 4 of a casing 3 in two halves bolted together and spaced apart by collars 7. Fig. 4 shows two of the devices adapted for use in suspending a laminated carriage spring 8 from a frame 9. In another construction, the spring 1 is formed as a continuation of a lamination of the carriage spring 8.

Filed: 1921-05-31
Abstract: 189,732. Marks, E. C. R., (Sanford Riley Stoker Co.). May 31, 1921. Mechanical stoking. - In mechanical stokers of the type where the fuel is fed from a hopper by a reciprocating plunger in a. cylinder provided at the end adjacent the hopper with packing to prevent the leakage of coal-dust past the plunger, the packing 25 consists of a transversely-split resilient ring of internal diameter smaller than the diameter of the plunger 27. The resiliency of the ring 25 may be supplemented by resilient means such as springs 30, 32, provided with adjusting means. The ring and its groove may have inclined engaging surfaces, so that the pressure of the ring on the plunger is increased when the piston is moving away from the hopper. The ring may also have a bevelled edge to permit of the easy insertion of the plunger in the cylinder.

Abstract: 1,095,986. Dynamo - electric machines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 26, 1966 [June 18, 1965], No. 25911/65 Heading H2A. In a dynamo-electric machine, e.g. a small electric motor, the or each bearing 3, for supporting the rotor 1, is mounted in an end bracket 4 which is secured to an end of the stator core 7 and has a peripheral rim 4a arranged within a bore of the stator core near the rotor such that the thickness of the rim is accommodated either by larger internal diameter laminations at the end of the stator core or by smaller external diameter laminations at the end of the rotor core. The brackets 4 which may be of metal or synthetic material are secured by an adhesive applied at 7a or by bolts or strips which pass through bores or the conductor slots in the core. The laminations at each end of the core 7 may have a larger internal diameter bore for receiving the rims 4a or alternatively the rotor laminations may be recessed (at 1b, Fig. 2, not shown) so as to clear the rims 4a when arranged between the rotor and stator cores. The plain bearings 3 are retained in position by clips 5 (Fig. 1) and also by clip 9 (Fig. 2, not shown) ; these methods of attaching the bearings may be reversed (Figs. 1A and 2A, not shown). In further arrangements (Figs. 3-6, not shown), the rotor is mounted in a pair or a single plain bearing supported in one end bracket. The arrangement of Fig. 3 (not shown), is suitable for vertical operation, e.g. for driving a centrifugal dryer. The bearings may be replaced by ball or roller types (Figs. 7, 7A, 8 and 8A, not shown).

Filed: 1928-09-11
Abstract: 297,118. I. G. Farbenindustrie Akt.- Ges. Sept. 15, 1927, [Convention date]. Apparatus for making filaments.-The cakes of artificial silk &c. are washed, bleached, desulphurized, &c. and, if desired, dyed, dried and finished, while still in the spinning boxes, the latter being at rest during these treatments, the inner layers of thread being supported by perforated or permeable spools inserted into the cakes, and the liquids &c. being sucked or forced 'through the cakes. The spools used may be of a construction which permits their diameter to be varied, and in order to deal with the shrinkage of the cake that occurs during the treatments, there may be provided an elastic pad for keeping the layers of thread in place. Drying is effected by passing hot or cold air through the cakes; this may take place in the spinning boxes, but may be completed after the removal of the spools with their attached cakes from the spinning boxes, or after the thread has been transferred to another spool or reel, or has been brought into hank form. 'The cakes may be steamed while still on the spoils. As shown, a perforated spool H is inserted into the cake A which is supported in the spinning box B between washers F, J, the latter being provided to prevent flotation of the threads. The bottom of the box is perforated, and, during winding, a washer is fitted into the interior of the washer F. Piles of such boxes are supported in profiled plates fitted on the false bottom L of a vat K of rubber-coated iron, the boxes being held in position by means of a lid N provided with pressure pieces P supported by rubber washers 0 and held against the pile of boxes by means of springs Q. A pump S connected to the space below the false bottom serves for the passage of liquid, air or vapours through the cakes, and the pump may be of the reversible type so that the direction of flow may be reversed at intervals.
