Title: Triac structure
Inventor: GAULT JOHN M
IPC: H01L29/747
Filed: 1969-06-09
Abstract: 1,220,306. Semi-conductor devices. INTERNATIONAL RECTIFIER CORP. 9 June, 1969 [19 June, 1968], No. 29000/69. Heading H1K. The outer regions 27, 29 of a triac are laterally separated from one another by at least three times the minority carrier diffusion length in the central region of the device, and the device also has a gate region 28 of the same conductivity type as, but laterally spaced from, the outer region 27 on the same surface of the semi-conductor body 20. Electrically interconnected gate electrodes 33, 32 are applied respectively to the region 28 and to the adjacent region of the other conductivity type on another part of the same surface, main electrodes 30, 31 being provided on the two outer regions 27, 29. The latter electrodes may, as shown, shortcircuit the corresponding junctions between the outer pairs of regions. The Specification explains how the lateral separation of the regions 27, 29 will permit, for the conductivity-type sequence illustrated, a positive gate signal to cause firing of the device only when the main terminal 30 is negative relative to the main terminal 31 (i.e. S.C.R.-type operation), whereas a negative gate signal will cause the device to fire regardless of the polarity of the main terminals (i.e. normal triac-type operation). The device may be manufactured entirely by diffusion, but in the form shown the N-type regions 27, 28, 29 comprise parts of an epitaxial Si layer vapor deposited over both faces of the Si body 20 after an initial overall Ga diffusion to form a P-type shell and a selective etching step to define recesses in the sites where the regions 27, 28, 29 are to be formed. P is used as the dopant in the epitaxial layer, and excess material is then removed to leave the regions 27, 28, 29 isolated from each other. A groove 34 is etched and filled with a silastic potting material 35. Figs. 14 and 15 (not shown) illustrate a modified configuration for the electrodes on the upper surface of the device. The two gate electrodes may be replaced by a single electrode extending across the junction between the N-type gate region 28, Fig. 11, and the adjacent P-type region.

Title: System including two or more prime movers for driving a common load
Inventor: HALL JOHN WALLACE
IPC: F16D41/00
Filed: 1960-08-22
Abstract: 927,030. Turbine plant. DE HAVILLAND ENGINE CO. Ltd. Aug. 22, 1961 [Aug. 22, 1960], No. 29014/60. Class 110 (3). [Also in Groups XXIV and XXXIII] In a system having at least two prime movers which can be coupled to a common load, such as an aircraft having two or more gas turbines geared to a common drive shaft, one of the engines is connected to the load through a freewheel clutch which can be disengaged for both directions of rotation, and an hydraulically controlled locking device is provided for preventing return of the clutch from its disengaged to its free wheel condition except when the output shaft of the clutch is rotating faster than its input shaft. The clutch may be of the kind having balls or rollers held in a cage which can be shifted axially to disengage the clutch, or the clutch may be as described in Specification 922,241. As shown in Fig. 2 the clutch is controlled by means of a fork 20 fast with a rotatable shaft 21. Pumps 10, 11 are so geared to the input and output shafts of the clutch that they rotate at the same speed when the input and output shafts rotate at the same speed, and the capacity of pump 10 is slightly greater than that of the pump 11, so that unless pump 11 is driven faster than pump 10, pressure builds up in a line 12 and a locking plunger 25 is moved to the right to engage an aperture in a lever 23 fast with the control shaft 21 which is thereby locked in its disengaging position. In a modification (Fig. 3, not shown) the pump 11 is replaced by a number of parallel connected pumps each of which is directly driven by an associated prime mover, and the capacity of each pump is an appropriate fraction of that of the pump 10. In another modification, Fig. 4, the fluid pressure controlling the locking device is supplied by a single differentially driven pump 52, 53. The clutch input shaft drives through a shaft 40 one side wheel of the differential, and the other side wheel is driven by the other engine. If there are several such other engines they may be coupled to the side wheel through free wheels 43, 46 &c.

Abstract: 152,605. Aktiebolaget Svenska Kullagerfabriken. Oct. 16, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Rollers, treating.- The spherical end surfaces of rollers &c. are ground by supporting and moving the rollers so that there is effected between these and the grinding-surface relative movement comprising in part a swinging about the centre of curvature of the roller ends and in part rotation about an axis passing through that centre. The rollers 3 are mounted in a cage 4 having pockets or other means therein to support and rotate the rollers with their axes passing through a common point 0 on the axis of the shaft 5 of the cage, and the spherical grinding-surface, which has a curvature equal to that of the roller ends, is formed on a disk 1, the axis of which intersects that of the shaft 5 at the point O. The grinding-surface has its centre of curvature at the point 0, and is concave for convex-ended rollers and vice versa. During grinding, the disk and the cage are rotated, preferably at unequal speeds, the inclination to each other of the axes of rotation causing the swinging movement of the rollers relatively to the grinding-surface; the entire surface is thus utilized and is worn uniformly. In a modification, the grinding-disk may be stationary and the roller-cage rotated about its own axis as well as about the axis of the grinding- disk.
