Title: Improvements in or relating to two-stroke cycle internal combustion engines
IPC: F02B25/00
Filed: 1944-04-05
Abstract: 578,638. Two-stroke engines; lubricating. WAERN, B. A. De. April 5,1944, No. 6337. [Class 7 (ii)] In a two-stroke engine with crank case compression, a pump cylinder 19 having a piston driven from the driving gear of the main piston assists by its inner side the crank case compression and by its outer side compresses a further charge into a receiver 25 which has valve-controlled communication with the combustion chamber. The main piston 8 draws in its charge through a non-return valve 21 and the compressed charge is transferred to the combustion chamber by a passage 43. The compression of the supplementary charge which, in a gas engine, may be gas, is controlled by valves 23, 24 and its delivery by a valve 26 or by piston-controlled ports. The pump cylinder 19 may be duplicated by arranging two pistons driven from cranks on the main crank shaft on either side of the main crank and in a two cylinder engine the two pump cylinders may be arranged at either end of the crank shaft. By this arrangement, the inertia forces are counterbalanced. Lubricant is delivered by a pipe 37, Fig. 4, to a recess 41 in a flange on the main shaft and thence it passes by a passage 39 to the crank pin 12 carrying the pump connecting rod. A flange 31 throws lubricant through a shield 30 to a channel 34 leading to the main crank pin. A pipe 40 also supplies lubricant to the main crank pin through an annular flange 36 and a channel 35. The pump crank pin may be formed as an eccentric and in this case, lubricant from the pipe 37 enters an annular recess therein the width of the driving gear being reduced thereby. The upper part of the crank case may be formed as storage chambers for lubricant after removal from the crank case and purification, the lubricant flowing back to the pipes 37, 40 by gravity.

Abstract: 947,674. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. Feb. 20, 1962 [Feb. 27, 1961], No. 6530/62. Heading H1K. In a monolithic two-stage transistor device comprising a first layer 13 (Fig. 5) of substan. tially intrinsic material of one conductivity type and a discontinuous second layer 12 of opposite conductivity type of which discontinuities 21 and 23 define the first and second transistor stages, the latter comprise emitter 26, base 16, collector 54 and emitter 28, base 18, collector 56 regions respectively and are interconnected by at least one resistor, e.g. 17, Fig. 1, which is formed by a portion of the second layer. Initially, a wafer of n-type silicon (100-200 ohm cm.) is heated at 1200 C. for approximately 1¢ hours in a Ga atmosphere after which one major surface of the wafer is lapped to expose the original material and cavities 50, 52 are formed therein. A foil of gold doped with antimony is alloyed to the cavities at a temperature of 700 C. to form collector regions 54, 56. An alternative method in which phosphorus is diffused into the cavities after which aluminium is deposited to form the collector electrode is also described. Foils 58, 61, 30, 31, 44, 46 and 48 (Fig. 1) of p-type material and foils 26, 28 of Sb-doped Au are then alloyed to the untapped major surface after which, and using a photo-resist method, scribe lines 21, 23 which penetrate the upper p-type layer are etched in this surface to isolate the two stages. An oxide of silicon is evaporated on to the device to form an insulating layer and then aluminium is deposited through a mask to join the emitter electrodes 26, 28 to foils 30, 31 respectively as indicated at 34, 36. The collector electrodes are joined to foils 44, 46 respectively by discharging a capacitor therebetween as is described in Specification 908,553, after which the device is cleaned and encapsulated. An alternative method in which diffusion techniques are used instead of alloying is also mentioned. The way in which the stages are coupled via the resistive portions 17 and the manner of supplying battery and earth via contacts (foils) 48 and 30 respectively and thence through resistive portions 19 and 64 can best be seen by comparing Figs. 1 and 8.
