Abstract: 429,428. Valve circuits for wireless reception. ROBINSON, E. Y., Garvary, Dryden Road, Bush Hill Park, Enfield, Middlesex, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Nov. 8, 1933, Nos. 31157 and 33212. [Classes 39 (i) and 40 (v)] In a receiver comprising two high-frequency amplifiers the gain of said amplifiers is controlled by potentials derived from the output of the first and the input to the second respectively. As shown the grid bias for highfrequency amplifying valves 1, 2 is derived from the load resistance 7 of a diode rectifier 6 incorporated in the valve 2 and fed through condenser 5 with the whole of the voltage from the secondary of the coupling transformer 12 from a tapping of which the grid of valve 2 is fed with high-frequency energy. Alternatively a condenser potential divider may be connected across the coil 12 for supplying the valve 2. In order to obtain a constant output from varying signals applied to the valve 2, the valve may be arranged to have a hyperbolic characteristic connecting grid volts and mutual conductance. In a further embodiment Fig. 3, (not shown), the valve 2 has a plurality of grids arranged for volume control by the method described in Specification 408,256 the anode being screened from the input grid and the gain of the valve varying hyperbolically with the bias on the gain controlling grid. The valve may contain one or more diodes and the anode may be led out of the valve at a point remote from the leads from the other electrodes, additional screens in the form of added flanges or the like being provided therein to reduce the capacity from anode to grid and anode to diode or diodes. Specifications 377,307, 408,531, and 413,390 also are referred to.

Title: Semiconductor devices
IPC: H01L21/00
Filed: 1960-09-13
Abstract: 952,361. Semi-conductor devices. RADIO CORPORATION OF AMERICA. Sept. 13, 1960 [Sept. 29, 1959], No. 31576/60. Heading H1K. A rectifying barrier in a semi-conductor wafer is provided by separately heating the wafer and a charge of impurity above the melting- point of the impurity, flooding the wafer with the impurity, cooling to effect partial recrystallization and then decanting the rest of the melt. In one example, an N-type germanium wafer 10 is placed in one end of a boat 11 while a charge 12 of indium is placed at the other end. The boat is heated in furnace tube 13 while tilted and the tube is then moved to the horizontal so that the molten indium floods over the wafer. After slow cooling (e.g. 5 ‹ C. per minute) so that a P-type recrystallized region forms on the wafer, the boat is again tilted so that the remaining indium flows away from the wafer. The operation is carried out in an atmosphere of 9 parts of nitrogen to one of hydrogen, or in nitrogen or helium. Alternatively the charge may comprise lead or consist of an alloy of 99% tin and 1% antimony or of gallium saturated with germanium and silicon or of 25% germanium, 73% indium and 2% gallium. The charge may be initially saturated with germanium and the wafer (heavily doped) heated to a temperature slightly (e.g. 10‹ to 100‹ C.) above that of the charge so that on flooding only a small part of the wafer is dissolved, whereby the thickness of the dissolved portion may be closely controlled. The acceptor concentration in the recrystallized region may be about 10<SP>20</SP> atoms per c.c. to provide a tunnel diode. As an alternative to provide a temperature gradient before flooding, the wafer may be heated to a predetermined higher temperature after flooding with the saturated charge to achieve the same result. The semiconductor may consist of germanium, silicon, germanium-silicon alloy, silicon carbide, the phosphides, arsenides and antimonides of aluminium, gallium and indium, and the sulphides, selenides and tellurides of zinc and cadmium. Intrinsic material may be used to provide PI, NI, &c. junctions. Germanium-silicon layers on silicon or germanium or gallium arsenide layers on gallium phosphide may be provided.

Abstract: 848,205. Road-vehicle spring-suspensions. MORGAN, H. R. Jan. 17, 1958 [Oct. 17, 1956; Oct. 26, 1956; Nov. 20, 1956], Nos. 31624/56, 32706/56 and 35468/56. Class 108(2). A road wheel is suspended by a Watt type linkage having one cam 7 and one joint 12 sufficiently massively proportioned to resist tilting of the wheel carrier 1. Lateral movement of the wheel carrier due to vertical movement of the outer end of the corresponding drive-shaft 4 is permitted by axial sliding of the bearing 13 in the link 2. There may be roller bearings (constrained against axial movement) between the bearing 13 and the link 2 (Fig. 5, not shown). In modifications, this play is alternatively taken up at the universal joint 5 (Fig. 1, not shown), at the joint 12 (Fig. 2, not shown), or by axial movement of the journal pin 11 of the link 7 (Fig. 1, not shown). In Fig. 6, the link 7 is connected to the vehicle frame by ball-jointed or rubber hinged shackles 19, 20 to permit its lateral movement. The pivot pin 11 of the link 7 may be rigid with a laterally-extending torsion rod (Figs. 9 and 10 not shown). The link 7 on one side of the vehicle may be forwardly extending while that on the other side is laterally extending.

Abstract: 365,205. Making paper &c. containers. WARE, H. M., Seletar, Dene Road, Northwood, Middlesex. Oct. 21,1930, No. 31653. [Class 99 (ii).] Apparatus for joining paper and like flexible sheet material, particularly in the formation of containers for solids or fluids, by means of overlapping tongues, as described in Specification 337,810, [Class 99 (ii), Pipes, tubes, &c.], comprises a mandrel having a series of dies coacting with a punch to cut out a series of tongues in the parts to be joined, one part being then moved over the other, so that the tongues of one part overlap the uncut material of the other part. The parts are then pressed together, and may be waxed or otherwise proofed. An apparatus suitable for producing containers of the form shown in Figs. 2 and 3 from blanks of the form shown in Fig. 1 comprises a mandrel 1, Fig. 5, below which is a clamping-member 10 mounted on a pivot 11. The blank is placed in position with the part A on the member 10, which is then raised bv the operation of a pedal to clamp the blank against the underside of the mandrel. The further action of the pedal raises pivoted folding - members, which bend the edges D of the blank over the rounded edges of the mandrel. The part B of the blank is then bent over the end of the mandrel, and is laid along the parts D and held in position by a spring clip 20. A hand-lever 7 is then operated to bring a piercing- head 6 down on the blank, so as to cause punch teeth 21, Fig. 9, on plates 22 to enter the die apertures 23 in the mandrel and to punch lines of tongues T out of the overlapping parts of the blank, the incision of each tooth forming three sides of a rectangle. The hand-lever is then released, and the head 6 rises slightly but is retained by a catch 25. A member 27, which is spring-pressed against the blank, and has indiarubber &c. on its underside, is then moved endwise by a hand-lever 28 and draws the part B of the blank over the parts D, so as to cause the tongues and apertures to interlock, as shown in Fig. 10. The container body is then withdrawn from the machine and is placed on a plain mandrel, the upper surface of the joint being then rolled with a rolling-pin, so as to produce the effect shown in Fig. 11.
