Title: A method of diffusing a conductivity-affecting impurity into a semiconductor compound
IPC: H01L21/00
Filed: 1961-05-01
Abstract: 979,554. Semi-conductor devices. TEXAS INSTRUMENTS Inc. May 1, 1961 [May 2, 1960], No. 15721/61. Heading H1K. A PN junction is produced in a body of a compound semi-conductor by heating the body and a source of donor and/or acceptor impurities to the same temperature in a closed vessel to diffuse the impurity or impurities into the body to form the junction. The source is an alloy of an inert material and the impurity or impurities which is molten at the temperature used. The body may initially be of N or P type conductivity or intrinsic. When using A III B v  compounds indium, gallium, aluminium, and lead may be used as inert materials, zinc, cadmium and mercury as acceptors, and sulphur, selenium and tellurium as donors. Gallium and indium are particularly suitable inert materials since they also act as getters, e.g. for oxygen, and thus assist in purifying the surface of the body. In a typical method a wafer of gallium arsenide is etched and then placed in an evacuated sealed tube containing an alloy of 99% (atomic) gallium, 1% zinc or of 99.9% gallium and 1 % zinc and heated at 800 C. for 7¢ hours. The method enables the surface concentration of the impurities in the semi-conductor body to be controlled by adjusting the proportion of the impurities in the alloy melt.

Title: Improvements relating to hand irons
IPC: D06F75/40
Filed: 1952-06-24
Abstract: 709,795. Hand-irons. HOOVER, Ltd. June 24, 1952 [June 29, 1951; June 29, 1951], No. 15854/52. Class 138(2) A hand iron has a rest including a straight elongated plunger 22 normally retracted within the iron to allow the sole plate 10 to rest on a supporting surface and having one end in line with a' hole 27 in the sole plate, and means for moving the plunger longitudinally so as to project from the .hole to support the forward end of the sole plate clear of the supporting surface. The plunger 22 may be projected by a spring which is strong enough to raise and support the forward end of the iron. In Fig. 2 a tension spring 24 is anchored to the sole plate 10 by a screw 26 while the upper end of the spring extends into a hole in the plunger. The lower turns of the spring may be of reduced diameter to keep the plunger out of direct contact with the sole plate. The plunger is guided by a roller 35 mounted in a rearwardly opening recess 36 in the sole plate and by a pair of rollers 28 carried by the plunger 22 and running on trackways 29 on opposite sides of a cavity 23 in the handle pillar. By pressing the toe of the iron against a supporting surface the plunger can be pushed up almost to its fully retracted position, with its top end 32 projecting from the handle. By pressing the part 32 rearwardly, the rollers 28 are made to ride up on to shoulder portions 31 of the trackways 29 and into depressions 33 which thus lock the plunger clear of the supporting surface. The cavity 23 may be covered by a closure member 37 having a hook 38 engaging in a recess in the forward wall of the cavity. A leaf spring 41 moves the member 37 rearwardly when the plunger. is retracted In a modification, Figs. 3 and 4 (not shown) a compression spring is used in place of the tension spring 24 and the plunger passes through a hole in a U-shaped guide bracket screwed to the underside of the cover plate. In a further embodiment (Fig. 6) the plunger 60 is held in its retracted and extended positions by an overcentre mechanism including a torsion coil spring 67 and manual control member 70. The spring 67 is formed in two similar halves Fig. 7 (not shown), on opposite sides of the plunger and joined by a section 68 passing through a hole in the plunger. The opposite end of each half of the spring is pivotally supported in the control member 70 which has a pair of side flanges 71 pivoted to the handle by a pin 74 frictionally held in holes in the handle pillar. The upper end of the plunger 60 is forked and carries n roller 64 engaging trackways 65, 66 integral with the handle pillar. When the plunger is in the region of its retracted position the spring 67 can be moved over its dead centre position in one direction by a finger piece 76 projecting through an opening 77 in the top of the handle and in the other direction by a member 78 which projects downwardly from the handle grip and is adapted to be actuated by the user's forefinger.

Title: Improvements relating to apparatus for regulating the supply of air from a compressor to an enclosure
IPC: F04D27/02
Filed: 1944-08-24
Abstract: 590,475. Air compressing. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 24, 1944, No. 16122. Convention date, Sept. 30, 1942. [Class 8 (i)] [Also in Groups XXVI and XXXV] The delivery of air from a compressor 2, to a chamber 1, which may be the pressurized cabin of an aircraft is regulated in accordance with (a) the quantity of air delivered and (b) the temperature of the air delivered. The speed of the driving motor 3 is controlled by the air pressures in pipes 9, 10 acting on bellows 11, 12, to tilt a rheostat control lever 13 to alter the resistance 6 in accordance with the air demands in the cabin 1. A hand-switch 14 is provided in the cabin. A valve 15 is controlled by the pressure in the cabin, through pressure on the bellows 16. A throttle valve 18 is positioned by a reversible electric motor 21, controlled by a temperature-responsive device 31 which heats fluid in a pipe 30 and bellows 29, to effect movements of a contact arm 28. The bellows 29 is in a sealed chamber 32 and thus free from the influence of atmosphere temperature or pressure. Upon increase in temperature of the air at 31, the field winding 23 is connected to operate the motor 21 and open the valve 18 wider. It the temperature of 31 decreases, the arm 28 contacts a stop 26 to close the circuit of the winding 22 and reverse the motor 21, and partially close the valve 18. A further control means comprises two sets of bellows 33, 34 under control of pressures in the compressor intake and delivery 4, 5, respectively. When the pressure ratio reaches a pre-determined figure, a rod 35 is moved to disconnect contacts 39, 40 then opening winding 22 so that valve 18 cannot be further closed and over-rides the device 31. Further increase in the pressure ratio brings contacts 36, 37 together to complete the motor field 23 in circuit, independently of the device 31.

Abstract: 200,326. Forkel, O. June 10, 1922. Planing. - Reversals are cushioned by an energy-storing device which accelerates the reversed member until it can be coupled to the driving-mechanism without shock. A shaft 19, Fig. 1, driven constantly in one direction from pulley 95 &c., carries a toothed pinion 9 and a sprocket 10 through which loose clutch members 6, 5 are driven reversely. A lever 64 actuating a double clutch 8 on a reversed shaft 20 is operated by means shown in Fig. 5 from a reciprocating table 30 driven from the shaft 20 through a bull wheel 1, Fig. 1. An intermediate shaft 21 carries a loose chain drum 78 connectable by a clutch 22. Near the end of its stroke, the table strikes a bowl 27 which throws in the clutch 22 causing the drum 78 to wind up a chain 32 and store energy in the device 39. This may be a pneumatic cylinder connected to a reservoir 41 and operated by a guided piston 38 pulled by the chain 32. To equalise the accelerating effect, the drum 78 has the eccentric shape shown in Fig. 3. An additional By-wheel 18, Fig. 1, is thrown into action on a slow working stroke by a clutch 15 to increase the kinetic energy on such stroke. Hydraulic means, or springs, or weights may be used to store the energy instead of the pneumatic means shown in Fig. 1.

Abstract: 737,872. Aerials. STANDARD TELEPHONES & CABLES, Ltd. July 4,1952 [July 9, 1951], No. 16218/51. Class 40 (7). The Specification describes various arrangements for preventing mis-match in an aerial system wherein a primary element situated at the focal point feeds into a concave mirror reflector and a structural member lies in the path of energy passing out from the reflector. In such a system energy reflected back by the obstruction normally passes from the mirror reflector back to the primary element and creates mismatch and standing waves. In one arrangement, wherein the rectangular guide 4 feeds the primary radiator 2 and the surface 5 of the guide provides a reflecting obstruction from which energy is directed back via the mirror to the primary element 2, a dummy extension 6 to the guide is provided faced with a metal plate 8 of a quarterwavelength thickness from the surface 7 of which energy is reflected back in antiphase to that reflected from surface 5. In a modification a thinner strip of metal is spaced out from the dummy guide 6 to the required position. In another arrangement a reflecting surface applied over a sufficient length of guide 4 and a quarter wavelength above it is used to cancel signals reflected by the remaining part of the guide. It is stated that a compensating reflector divided in two halves spaced one a quarter-wavelength in front of, and the other a quarter-wavelength behind, the plane of an obstructing surface gives compensation over a wide bandwidth.
