Abstract: 534,077. Combustion chambers. MARCHANT, W. D., and MOTOSACOCHE SOC. ANON. May 15, 1939, Nos. 14485 and 14486. Convention dates, May 17, 1938, and May 12, 1939. [Class 7 (ii)] The combustion chamber of a side-by-side valve engine is substantially triangular in plan, is stepped as shown in Fig. 1 in a plane which passes through the inlet and exhaust valves 13, 14, respectively and is shaped as shown in Fig. 3 in a plane which passes through the inlet valve 13 and the cylinder bore. The chamber E may increase in depth towards the cylinder as does the chamber A shown in Fig. 3 ; a sparking plug is located above and between the valves and approximately at the centre of the complete combustion chamber. The distances between the edges of the valves and the cylinder cover increases in the direction of the cylinder and to facilitate heat transfer the thickness of the walls of the chamber E is greater than the general thickness of the wall. Also, to increase the cooling effect in the neighbourhood of the exhaust valve the water circulation is increased in this region.

Patent GB-593601-A (GB)
Title: Improvements in remote control systems
IPC: H04Q9/06
Filed: 1945-06-08
Abstract: 593,601. Selective control. BRITISH THOMSON-HOUSTON CO., Ltd., and MOIR, J. June 8, 1945, No. 14495. [Class 40 (i)] A remote control system comprises a number of relays 1, 2, 3 which are connected in series, Fig. 1, or in parallel, Fig. 2 (not shown), with a supply 4. The current flowing through the relays is insufficient to operate them, but sufficient to maintain them in that position when they have operated. The operation of a " push-button " switch A, B or C, Fig. 1, situated at a remote point, momentarily shortcircuits all but the appropriate relay which operates due to the increase of current. Any relay which has previously operated "dropsout" when it is short-circuited. When a large number of relays are to be controlled, a non- linear resistance 10 is connected in series with the relays. The relays may be controlled from more than one point by connecting switches such as A1, B1, C1 in parallel with the switches A, B, C. In a modification, Fig. 2 (not shown), a number of parallel branches, comprising a preferably non-linear resistance 10 connected in series with a common resistance across the supply. The operation of a switch A, B or C short-circuits the individual resistance and the appropriate relay operates. The short-circuiting of the resistance causes the voltage across each branch to fall, thus any previously operated relay "drops-cut."

Title: Semiconductors
IPC: H01C1/144
Filed: 1960-04-26
Abstract: 879,898. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. April 26, 1960 [May 5, 1959], No. 14532/60. Class 37. A process for producing semi-conductor wafers with accurately positioned electrodes comprises the steps of applying a strip of contact material to the full length of each of at least two opposed sides of an elongated semi-conductor body of substantially rectangular cross-section, holding the strips in place, heating the assembly to fuse the strips to the body, severing the body and strips in a direction transverse to their longitudinal axes to produce semi-conductor wafers each having at least two contact electrodes fused thereto. As shown, Fig. 6, in the production of Hall generators, an elongated body 210 of indium arsenide is disposed in a graphite jig 130 comprising a base 132 (see also Fig. 7) and a duplicate top member 134, each having a cavity which accommodates half of the body 210. Contact strips 212, 214 of tin-lead (60%:40% by wt.) alloy, co-extensive with two opposite surfaces of the body, are disposed next to these surfaces, and two narrower contact strips 216, 218 of similar composition are located in slots 135, 139 so as to be in contact with two other opposite surfaces of the body along the entire length of such surfaces. The assembly is heated in a non-oxidizing atmosphere, e.g. argon, to a temperature between 300‹ and 500‹ C, e.g. 400‹ C, and maintained thereat for a few minutes while a pressure of about 200 grams per square inch of contact surface is applied. After cooling, the body, Fig. 3, with contacts fused thereto, is cut into slices as at 20. Leads may be fixed to the electrodes of each resultant wafer by soldering or by heat-softening the contact material, embedding the end of a lead in it, and resolidifying. In another example, contact material comprising 99% gold, 1% antimony by weight is fused to a body of silicon at 500-800‹ C., e.g. 600‹ C., with a pressure of 100 grams per square inch, the wafers being lapped with fine alumina abrasive. In a further example, contacts of pure tin are fused to a germanium body at 500‹ C. and a pressure of 50 grams per square inch, the wafers being lapped with silicon carbide. Fig. 8 shows an alternative form of jig comprising a base 138 having a cavity 139 to accommodate the body and contact strips 312, 314; walls 141, 142 of the cavity comprise slots 143, 144 which hold the contact strips 316, 318. The cavity 139 is closed by a top member 140. Other III-V compounds, e.g. indium antimonide, indium antimonide-indium phosphide, may be used for the semi-conductor body, and the contact material may be of gold, silver, lead, tin or a mixture of two or more in a base alloy, e.g. silver-tin, silver-lead, gold-silver-tin. Magneto-resistors and Ettinghausen effect devices may be similarly constructed.
