Title: Improvements in or relating to apparatus comprising a semiconductor cirucuit element
IPC: H01L23/40
Filed: 1964-04-02
Abstract: 1,064,099. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 2, 1964 [April 5, 1963], No. 13645/64. Heading H1K. Part of a terminal or an insulator carrying a terminal is clamped between a cooling body and a pressure member, the clamping means also holding the metal envelope of a semi-conductor device to the body. In the Fig. 1 arrangement the envelope 6 is bolted to finned cooling body 6 and clamps pressure member 7 over the head of terminal bolt 12 and the base of insulating terminal support 14. Rotation of the bolt and support is prevented by engagement of the bolt head with mating recess 18 and of the support with the edges 8 of the pressure member. Heat transfer to the fins is facilitated if the base of the envelope has a raised portion about the threaded stem which passes through hole 9 to directly engage the cooling body. In a further assembly, Fig. 3, the cooling body has lateral fins 32 and recesses for bolt head 35 and the enlarged base 41 of an insulating terminal post. The latter carries two terminals for the semiconductor controlled rectifier 32, Fig. 6 (not shown) and its rotation is prevented by threading its essentially semi-circular stem through a matching hole in the pressure member 34.

Title: Improved mechanism for controlling the sequence and periodicity of operations of a machine
IPC: B65H20/04
Filed: 1920-05-19
Abstract: 167,612. Swift, G. W. May 19, 1920. Operating clutches. - An intermittent operation is started at variable intervals by actuating clutch and brake mechanism through tap - pet gear so arranged that as each tappet comes into play a fresh tappet is automatically brought into operative posi tion for affecting the next operation, the tappets s being mounted on a continuously moving disc. The invention is shown applied to a papercutting machine having a continuous feed, with rotary cutters intermittently brought into action to cut off sheets. A rotary wheel 30 has a number of pins or tappets 31 which normally project to the front of the wheel, as seen in Fig. 2. They may, however, be pressed backwards and then, as the wheel rotates, they bear against an arm 59, which, through the weigh-shaft 56 and rod 73, Fig. 1, frees a brake 78, and through a lever 60 puts a clutch into action. This starts rotary shafts 8 carrying cutters 7. which sever a sheet from the web 1 continuously fed by wheels 5. Each time the weigh-shaft 56 rocks, it actuates a hammer-lever 40 through linkage 55, 54, 52. The hammer-lever, which by means of a head 37 having a limited displacement knocks a tappet 31 into active position, is carried by an arm 45 which can be set at any radius, so that as one tappet bears on the arm 59 it automatically positions a tappet for completing a subsequent operation. After the tappet has operated the arm 59, it meets a cam-surface which presses it back into inoperative position.

Title: Improvements in or relating to gas turbine engines
Inventor: DAVIS RALPH NORMAN
IPC: F02C7/047
Filed: 1949-05-25
Abstract: 668,863. Gas turbine plant. BRISTOL AEROPLANE CO., Ltd. May 22, 1950. [May 25, 1949] No. 14036/49. Class 110(iii). [Also in Groups XXV and XXXIII] A gas turbine engine installation comprises a ram-air inlet leading to the compressor of the engine, a debris guard at the air inlet, an auxiliary air inlet at a region normally free of ice formation, a conduit to convey air to the compressor from the auxiliary inlet over the engine whereby it is heated and closure means for the auxiliary air inlet which automatically open when the guard becomes blocked. A propeller turbine engine 5 has a normal air inlet formed by a duct 14 leading from a forwardlyfacing inlet 16 and an auxiliary inlet formed by openings in the rear end of the engine cowling, the space inside the cowling around the engine and an annular passage 19. The front end of tne passage 19 which is formed between the cowling skin and an inner wall 20 carried by the engine connects with the duct 14 downstream of a guard grid 18 and the rear end is closed by a plurality of spring-loaded flaps 22. The openings in the rear end of the cowling are closed by spring-loaded shutters 23. The arrangement is such that when the grid 18 is blocked by ice, the suction of the compressor 9 opens both the shutters 23 and flaps 22 and air flows over the'engine, where it is heated, into the compressor. In normal operation, air flows through the duct 14 into the compressor. Part of this air flows through the passage 19, through holes in flaps 22, Fig. 2, into the engine space, and is discharged from this space around the tail pipe 12. Several rows of shutters 23 may be provided and the strength of the shutter springs so selected that the shutters open in predetermined succession as the suction effect in duct 14 increases. The flaps 22 are pivoted on the wall 20 by means of a bell-crank 26, one arm of which is connected to a plunger 27. The plunger is loaded by a spring 28 mounted between concentric sleeves 29, 30. Specification 592,091 is referred to in the Provisional Specification. Reference has been directed by the Comptroller to Specifications 579,657, [Group XXXIII], and 692,091.
