Abstract: 896,935. Soldering. GENERAL ELECTRIC CO. Ltd. Feb. 27, 1959 [Feb. 27, 1958], No. 6359/58. Class 83 (4). [Also in Group XXXVI] A lead wire is soldered to the surface of a semi-conductor body containing a PN junction by preparing the wire so that only the tip is readily wettable by the solder, and arranging for the surface of the semi-conductor to be more easily wetted by the solder than the surface of the wire contiguous with the tip. The drawing shows an N-type germanium wafer 1 with P-type emitter portion 2 and P-type collector region 4. A beryllium-copper wire 3 is first heated to provide an oxide coating 6, then cut to provide a clean surface and dipped into a tin-lead-indium solder to form a coating 7 on the clean end portion only. The wire is then brought into contact with emitter region 2, zinc chloride sprayed on as a flux while the semi-conductor is heated to just below the melting-point of the solder, and hot gas then used to melt the solder. The device is then washed in deionized water and potassium cyanide. Aluminium may be used instead of beryllium-copper, a coating of special flux being applied to the tip of the aluminium wire which renders the oxide coating process unnecessary.

Title: Improvements in or relating to machines for operating upon boot and shoe soles
IPC: A43D25/18
Filed: 1929-02-27
Abstract: 334,179. British United Shoe Machinery Co., Ltd., Holmes, W., and James, C. H. Feb. 27, 1929. Coating-machines.-In a machine for performing channelling operations on boot and shoe soles, such, for example, as that described in Specification 322,506, [Class 17 (i), Boots and shoes, Apparatus for making &c.], adhesive, such as rubber latex, is simultaneously sprayed on to the mechanically fed and guided sole. Attached to the main body 8, Figs. 1 and 2, of the spray is a tube 3 to the interior of which adhesive is admitted through a pipe 9 and compressed air enters the annular chamber 4 surrounding the tube 3 through the pipe 11. At the extremity of the conical cap 13, clipped to the tube 3 by screw 12, an opening 14 surrounds the reduced end 2 of tube 3, forming an annular space from which the compressed air is discharged. The discharge of adhesive is regulated by a needle valve 5 working in a central orifice 1 of the reduced end 2 of tube 3 and forms an extension of a plunger 6 controlled by a spring 7. The threaded end of the plunger 6 is fitted with a nut 15 engaged by a pin 16 carried by a lever 17 pivoted at 18 on a bracket 19 which is pivotally mounted on a slotted quadrant 20 and clamped by a screw 20a. A screw 20d in the quadrant 20 affords extra. support for the bracket 19. The lever 17 is operated by a lever 22 pivoted on a spindle 21 and a link 23 from a treadle (not shown). In a modification, Fig. 3, the supply of air is controlled by a needle valve 2,5a and spring-controlled plunger 25 in a manner similar to that by which the flow of adhesive is regulated, the nuts 15 being engaged by a lever 17a actuated by a link 17b. By adjustment of the nuts 15 so that a lost motion occurs between the lever 17a and the nut on the plunger 6, the air-controlling valve opens before and closes after the adhesive-controlling valve. The compressed air pipe line may include a bye-pass and control taps, whereby the pressure of air supplied to the spray may be regulated. Specification 309,523, [Class 17 (ii), Boots and shoes, Construction of], also is referred to.

[Also in Groups XI and XXVIII] A jet propulsion or gas turbine engine fuel system having a centrifugal pump supplying liquid fuel to a main burner is combined with an auxiliary pump of the hydraulic ram type which supplies fuel to an auxiliary burner nozzle at low idling speeds of the centrifugal pump. A centrifugal pump a discharges liquid fuel through control means e to a main burner nozzle c. A hydraulic ram pump fed with fuel through the pipe n supplies fuel at low idling speeds of the pump a to an auxiliary burner nozzle f, which may be incorporated with or arranged separately. from the main burner nozzle c. The hydraulic ram pump comprises a cylindrical chamber g housing a spring-loaded piston h. A sub-chamber m is connected to the chamber g through a spring-loaded non-return valve j and the intake of the centrifugal pump through a spring-loaded valve p. As the pressure on the pipe n falls the valve p opens and the valve closes. The resulting flow of liquid fuel along the pipe n closes the valve p and opens the valve j. Fuel then flows into the chamber g. This causes the pressure in sub-chamber m to fall and the valve p to open and the valve j to close. When is closed fuel is discharged from the chamber g to the nozzle f by the piston h.
