Title: A method of forming a film of GaAs and germanium materials
Inventor: HARPER ROBERT CAMERON
IPC: H01L21/20
Filed: 2009-02-19
Abstract: There is disclosed a method of epitaxially forming a thin film of a first material selected from GaAs and a germanium material for example, SiGe on a surface of a second material. The second material 12 is either GaAs or a germanium material and is chosen to be the other material not used for the first material. The surface of the second material is carried by a donor substrate 10 for example, a GaAs or Ge substrate. The first material is transferred from the donor substrate to a receiver substrate 20 for example a Si substrate. The receiver substrate may comprise an insulator layer (22, Figure 2A). There is one of; residual second material adjacent to the first surface attached to the first surface, and residual first material from adjacent to the second surface attached to the second material. The residual material is removed for example, by selective wet etching. The first and second materials may be lattice matched. ions may be implanted to initiate a cleave layer 14 in the first or second materials. Alternatively, a SiGe grade is grown on a donor substrate. The SiGe is graded from a SiGe material having a first composition to a SiGe material having a second composition. A layer of GE is grown on the SiGe grade and layer transfer of at least some of the Ge to a receiver substrate is carried out. The methods may be used to form photovoltaic cells, optoelectronic devices, or a Ge based CMOS device.

Title: Improvements relating to hydraulic actuating systems, for aircraft and the like
IPC: B64C25/22
Filed: 1939-03-31
Abstract: 531,465. Controlling aircraft; undercarriages. DOWTY, G. H. March 31, 1939, Nos. 10140 and 16844. [Class 4] [Also in Group XXIX] A hydraulic actuating system for aircraft and the like is described in connection with the actuation of undercarriage jacks 23, retractable radiator jacks 24, bomb door jacks 25, and flap jacks 26 by means of a common variable delivery pump 14 the output of which ceases when the output pressure reaches a pre-determined value. Examples of such pumps are described in Specifications 524,199 and 524,384, [both in Group XXVIII], and the invention covers the application to one jack only under control of a flow resistor means for raising the output pressure of the pump and thereby reducing its rate of delivery. A common outlet pipe 16 from the pump may be connected by means of control valves V, VI, V2, V3, to the jacks which are to be operated, or the valves may be set to connect the jacks to a return pipe 27 leading to a reservoir 11. An auxiliary hand-operated pump 18 may be arranged in the pump circuit and also a non-return valve 17. To prevent violent action of the smaller jacks resistance devices R, R1, R2, R3, R4, R5 are arranged in the supply and return pipes of the jacks 24, 25, 26. This may be effected by using smaller pipes, or valves with controllable passages, or by using a spring-controlled reduction valve 42, Fig. 7, with an aperture 45 selected in accordance with the use of jack to permit the fluid to operate the jack. The valve opens to allow of release of the jack. A hydraulically operated brake device may also be arranged in parallel with the jacks, its reservoir being charged by the pump 41 under control of a valve similar to the valves V-V3 the brake itself is under control of an additional valve.

Title: Improvements in or relating to radio transmitting systems
IPC: H03C1/60
Filed: 1937-04-09
Abstract: 483,883. Wireless transmitting systems. LORENZ AKT.-GES., C. April 9, 1937, No. 10159. Convention date, April 9, 1936. [Class 40 (v)] , In a high-frequency transmitter employing separate amplifiers for the carrier and the side-bands both of which feed the same aerial or line circuit, undesired inter-action between the two amplifiers is prevented by interposing a phase-shifting device between the carrier amplifier and the aerial or line. A complementary phase-shifting device is included either in the earlier stages of the carrier amplifier, or in some part of the side-band amplifier, in order to preserve the proper phase relation between carrier and side-bands in the final output. As shown, the carrier source 5 is modulated by speech signals from M and the resulting side-bands are amplified at I, II and fed to the aerial A through a final amplifier E1, which is preferably of the Class B type. The side-bands are separated from the carrier by using a push-pull modulator, or by a crystal filter. The pure carrier wave is amplified at III, shifted in phase by 90 in the device C2, and is fed to the aerial through an output amplifier E2 and a phase-shifting device C1 which shifts the phase of the carrier by 90 in the opposite direction to the device C2. The device C1 may comprise a quarter-wave-length of transmission line or concentric tube, or a phase-shifting bridge, or a chain network. To avoid distortion in the side-band amplifier E1, it is biassed back to the lower end of the straight part of its characteristic, and a rectifier is connected in the grid circuit, in the manner described in Specification 483,882, so that only positive half-cycles reach the grid. The rectifier may be a vacuum or a gas-filled diode, or may be grid-controlled. The rectifier characteristic may be straight or may be curved in such a way as to compensate for the lower bend of the valve characteristic.

Abstract: 646,533. Luminescent materials. BRITISH THOMSON-HOUSTON CO., Ltd. April 14, 1948, No. 10366. Convention date, April 15, 1947. [Class 39 (i)] A phosphor emitting ultra-violet radiations of longer wave length when excited by ultraviolet radiations of shorter wave length, par. ticularly for use in low pressure mercury discharge lamps, comprises magnesium phosphate of approximately pyrophosphate composition activated by both cerium and thorium. The thorium may be present in quantities varying from 0.001 to 15 per cent or more of ThO 2  and the cerium in quantities varying from 0.001 to 25 per cent of Ce 2 O 3 , preferably about 12 per cent ThO 2  and 13 per cent Ce 2 O 3 . The phosphor may be prepared by cold co-precipitation of magnesium, cerium and thorium phosphates as MgNH 4 PO 4  plus activators, followed by firing at about 900-1200‹ C. in steam and hydrogen to decompose the ammonium containing compounds with formation of activated Mg 2 P 2 O 7 . In another method 510 grs. Mg(NO 3 ) 2 .6H 2 O, 118 grs. Ce(NO 3 ) 3 .6H 2 O and 90 grs. Th(NO 3 ) 4 .4H 2 O are dissolved in 2 litres of distilled water and under vigorous agitation a cold solution of 400 grs. of (NH 4 ) 2 HOP 4  in 2 litres of distilled water is added followed by about 400 c.cs. of concentrated ammonia. After standing the precipitate is filtered, washed, dried and then fired in an atmosphere of steam and hydrogen for 1 hour at between 900-1200‹ C., preferably 1050‹ C. The material is then cooled in hydrogen and then sieved. Silica quantities of from 0.001 to 10 per cent, preferably 1 to 5 per cent, can be added to the phosphor before firing, either by adding finely divided silicic acid powder to the solution of nitrate before the phosphates are precipitated or by adding ethyl silicate, dissolved in alcohol, to the nitrate solution. After firing the silica may remain free, it may form some magnesium silicate or it may form a double compound with the phosphate. The Specification refers to cerium activated magnesium pyrophosphate and to ceriumthorium activated magnesium silicate. Specifications 550,744, 631,415 and 633,891 are referred to. The Specification as open to inspection under Sect. 91 refers to the use of bismuth, lead and tin as activators alone and in combination with thorium. This subject-matter does not appear in the Specification as accepted.

Abstract: 1339030 Rolling mills FRIEDRICH KOCKS 21 April 1971 [22 April 1970] 10387/71 Heading B3M  A rolling mill includes a roll stand in which at least two rollers define a roll gap, the two rollers having different diameters so that the larger one, after suffering wear and a regrinding operation, may replace the smaller one. The mill may include a number of such stands in tandem each having three rolls. Each of the rollers after being reground, may pass successively through the various stands of the mill. The rollers are suitably profiled to form rod, wire, tubes, or profiled bars. In a three roller arrangement as shown, the roller 2 has a normal diameter, whereas roller 1 is larger and roller 3 smaller. This means that the height of the pass line is unchanged but is shifted slightly laterally. If the diameter differences are small, the speeds of the rollers vary only slightly, but larger diameter differences may call for changes in the gear ratios of the roller drives.

Abstract: 554,070. Fluid-pressure servomotor-control systems. BRASSERT & CO., Ltd., H. A., and NISSIM, R. Sept. 15, 1941, No. 10427. [Class 135] Apparatus for controlling a physical value comprises a differential piston and cylinder, means for supplying pressure fluid on each side of the piston and an escape valve for varying the pressure on one side of the piston in accordance with changes in the physical value. Preferably, the movement of the piston controls a power cylinder. In the form shown in Fig. 1, flow variation in a conduit 30 acts through an orifice plate 32, diaphragm 33, lever 34 and escape valve 35 to vary the pressure in the space on top of the differential piston 38. The piston is therefore moved so that relay valve members carried thereby alter the supply of pressure fluid from the space beneath the piston to the power cylinder 50 for operating the control valve 45, and the exhaust from the power cylinder. The valve members consist of rings 51, 52 provided with ports 47P, 47E and separated by a space C communicating with drain. In other forms, the escape valve may consist of a needle valve 35A, Fig. 3, co-operating with a port in the piston, and the latter may be formed so that the pressure within it is completely balanced. In a modification of any of the above-mentioned forms, two ports 47P, 47E are replaced by a single port 47P as shown in Fig. 4A, co-operating with adjacent ports 48P, 48E. When applied to the form shown in Fig. 3, the cross-section of the single port is equal to the sum of that of the adjacent ports.
