Title: Improvements in liquid fuel burners
IPC: F23D11/46
Filed: 1945-09-14
Abstract: 599,165. Mounting liquid-fuel burners. BRITISH COMBUSTION EQUIP. MENT, Ltd., KEMP, W., and TOMLINSON, J. T. Sept. 14, 1945, No. 23716. [Class 75 (i)] In a liquid - fuel burner in which the fuel valve and a pinching screw for holding the sprayer in place are so arranged that the screw cannot be operated unless the valve is closed, the lever for operating the fuel valve loosely carries the operating key of the screw. In the position shown, in which the screw b has been actuated to break the joint between the sprayer a and the fuel supply and allow removal of the sprayer, a stop e<1> on the key e prevents its removal from the head of the screw and so prevents the turning of the manipulating lever f to operate the valve d. When the screw b has been rotated to actuate a yoke c to complete the fuel supply joint, the key e may be raised clear of the head of the screw b to allow rotation of the lever to operate the valve d.

Title: Improvements in or relating to electro-magnetic motors with reciprocating movement
IPC: H02K33/04
Filed: 1938-08-13
Abstract: 520,680. Diaphragm pumps. NAHMAN, G. Aug. 13, 1938, No. 23945. Convention date, Aug. 19, 1937. [Class 8 (i)] [Also in Group XXXV] The magnet 1 and/or the armature 2 of a reciprocating motor incorporated in a diaphragm-type pump is embedded in a block of thermoplastic material, and the magnet core is made up of radially arranged C-shaped laminations so as to constitute an annular body of C-section. The magnet laminations abut against a central metal tube 3 and are held in a moulded cap a which is cast about the magnet and its exciting coil 6. A metal base c screws into the cap and grips the edge of a diaphragm M moulded together with radial laminations l<SP>1</SP> into a thermoplastic disc b. The mouldable material extends into a tubular part b<SP>1</SP> which can slide along a guide tube D held by a nut E. The parts a, c may be held together by the nut E and the tube D whereby the screw thread 4 may be dispensed with. The armature 2 acts as the piston of the pump drawing in air or other fluid through a valve 8 and expelling it through a valve 9 into the pressure chamber Z, whence it flows out through the tube D. Springs 10 maintain the armature in the unattracted position and openings 11 in the cap allow air to enter freely above the armature. A buffer 7 may be incorporated in the armature. The mouldable material may be reinforced with inserts of other materials. The Specification as open to inspection under Sect. 91 describes also the following. The armature may consist of sheets staggered so that there is a greater number at the periphery than at the centre and instead of laminations, wire or other thin pieces may be used. The mouldable material may incorporate supporting guides or electrical accessories. Cooling is effected by the flow of the pumped fluid. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to semi-conductor devices
Inventor: BEALE JULIAN ROBERT ANTHONY
IPC: H01L21/00
Filed: 1958-07-29
Abstract: 899,063. Semi-conductor devices. MULLARD Ltd. July 29, 1958, No. 24404/58. Class 37. An electrical connection to each of a pair of projections on a semi-conductor mass is made by providing electrical connection between the two projections and a common conductor extending between them and beyond them in each direction and thereafter severing the conductor between the two projections. In Fig. 1, a pellet of bismuth containing 1% arsenic is lightly alloyed to one side of a slice of P-type germanium crystal by heating to about 650‹ C. in hydrogen. A slot 12 is cut across the resolidified layer of bismuth by ultrasonic cutting means, dividing it into two projecting parts 5, 6, and the assembly is etched in hydrogen peroxide. Aluminium is then deposited on the surface of the right-hand part 6 of the-divided resolidified layer and the device is again heated in hydrogen to about 750‹ C. The other surface of the crystal slice is then etched, a collector of indium containing 1 % gallium is alloyed to it by heating it to 500‹ C. in hydrogen and a stout nickel wire 9 is soldered to the resolidified indium 7, using an indium solder 10. A strip of silver 11 .is then brought into contact with the parts 5 and 6 and the device is heated to about 330‹ C. in hydrogen, thus alloying the strip to the parts 5 and 6, between which the silver strip is then severed. With the channel 12 protected by a drop of polystyrene lacquer, the device is electrolytically etched in an aqueous solution of sodium hydroxide, during which process the N-type layer 8 is removed. The transistor is then etched in hydrogen peroxide, washed, dried and encapsulated in any known manner. Fig. 1 shows the unchanged P-type region of the crystal 1, an N-type layer 2 due to the arsenic and bismuth, a P-type layer 3 due to the aluminium, an N-type layer 8 due to the fact that arsenic diffuses more rapidly than aluminium, a P-type alloy layer 4 in the crystal slice, and the two parts 5 and 6 of bismuth and arsenic and, in the one case, aluminium also. As a modification, an indifferent material such as lead may be alloyed originally to the crystal slice, a narrow channel provided in the resolidified material, an acceptor impurity added at one side of the channel and a donor impurity at the other side and alloying heat applied to provide the junctions. Fig. 3 shows another embodiment in which a slice of N-type germanium has two P-type zones 13 and 14 produced by alloying pellets of indium to the surface. The upper surface, including the projections 15 and 16, is then covered with a layer of polystyrene lacquer which is removed from the upper parts of the projections either by mechanical or chemical means. A layer of silver 18 is then applied, as by evaporation in vacuo, and is thereafter severed at 19 by ultrasonic cutting means. Specification 856,430 is referred to.

Title: Extinguishing chamber with differential piston for electric circuit breakers
IPC: H01H33/96
Filed: 1939-08-25
Abstract: 532,303. Liquid-blast switches. RONNBERG, D., and ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Aug. 25, 1939, No. 24524. [Class 38 (v)] In order to prevent discharge between the opened movable contact 28 and parts in conductive connection with the fixed contact 1 in a differential - piston type of quenching- chamber, the parts are so arranged that re-striking of the arc will occur between the contacts, as in originally opening the circuit, the arc being then dealt with in the normal way by the blast. The piston comprises metal cylinders 8, 9 fastened to insulating caps 6, 7 which are separated by a space 15. The collar of 9 slides on an inner cylinder 4 connected by fins 3 to a guide sleeve 24 slidable on the rod 2. When an arc is struck, piston 6 ... 9 descends and simultaneously cylinder 4 rises, thus squeezing liquid from the space between cylinders 4, 8 and forcing it on to the arc as the contact 28 clears the openings 16, 17. This form is suitable for incorporating in a close-fitting cylindrical insulator in which descent of piston 6 ... 9 necessitates escape of the external displaced liquid through the constricted space round the chamber. Since the upward movement of 4 enables adequate blast to be got with a reduced vertical descent of the piston, the resistance to movement of the latter is reduced. When the chamber is inverted at the bottom of the container the cylinder 4 is fixed. Valves 12 enable the piston to begin to move before the holes 16, 17 are uncovered, and also permit closure of the contacts, and valves 23 allow the arc-gases to escape. The cavity 18 is for retarding the collapse of pressure when the holes 16, 17 are uncovered.
