Title: Improvements in or relating to oil-filled cables
Inventor: BASKWELL JOHN ALFRED
IPC: H01B13/30
Filed: 1964-06-24
Abstract: 1,062,444. Impregnating and sheathing cables. PIRELLI GENERAL CABLE WORKS Ltd. Sept. 24, 1965 [June 24, 1964], No. 26157/64. Heading H1A. Fig. 4 shows apparatus for the manufacture of oil-filled cable in which the cable passes from a drying and/or impregnating tank to a sheathing station through a fluid tight tube. Initially, the cable core 12 is assembled in the tank with cable end plugs 12, 13 at its leading and trailing ends. The leading plug is connected to a pulling hawser 1 itself joined to a connector 4 which is located in a seal at the outlet of the tank. A small length of tube is then extruded from the press and into this is pulled by wire 20 a draw plug 18. The rear end of this plug is joined to a chain 6 with a spare length in a chain box as described in Specification 1,059,951. In the case of a pre-impregnation process the oil level in the tank is then lowered to empty tube 10 but to maintain the cable plug 2 covered. C0 2  is admitted to tube 10 and spills out of the tank entry thus excluding air. The connector 4 is then joined to the rear end of the pulling chain and the connecting tube joined to the tank mouth and to the sheathing press. The lead sheath is then compressed around plug 18 which is pulled into the sheath by wire 20. The C0 2  supply is now cut off and the tube and the space above the oil are evacuated. Extrusion proceeds until the leading cable end plug 2 is in the sheath and at the same time the connecting tube is filled with oil. Extrusion is then continued until the cable end lug 2 is ahead of the extruder when the sheath is cut ahead of the plug and the hawser removed when the cable is attached to the wind-up drum. A short length of hawser is provided between the cable and plug 13 and this is attached to a further plug 14 which enables the oil in the tank and the connecting tube to be emptied without ingress of air. This is achieved by sheathing until plug 14 is within the sheath when the sheath is cut behind sealing ring 8 in the end plug and the length of sheath and the hawser are removed. The construction of the cable end plugs forms the subject of divisional Specifications 1,062,446 and 1,062,447.

Title: Nail driving device
IPC: B25C1/04
Filed: 1955-09-13
Abstract: 779,042. Nailing apparatus. REICH, K. M., and REICH, K. [trading as REICH, K. M. [Firm of]]. Sept. 13, 1955 [Sept. 18, 1954], No. 26171/55. Class 89 (3). In a nailing machine operated by compressed air, the return stroke of the driving piston 6 is effected by compressed air forced into a storage space 21 during the driving stroke of the piston. In one embodiment, the piston 6 carries a ram 7 which during the driving stroke enters the bore 2 of a guide 3 into which a nail 4 has been fed from a hopper 5. As soon as the ram 7 enters the bore 2 the space in' the cylinder 1 below the piston becomes closed to the atmosphere and the air therein is forced through openings 22 into the storage space 21. When the nail 4 has been driven into the workpiece 8 the operating lever 18 of the control valve 10 is released so that at the valve 10 the space in the cylinder 1 above the piston is closed to the compressed air supply 20 and is opened to the atmosphere, whereupon the compressed air in the space 21 returns the piston 6 to the upper end of the cylinder 1 where it is retained by a spring- loaded detent 23 in readiness for the next nail-driving operation. In a modification Fig. 3 (not shown) the nail driving ram is separate from the driving piston and is permanently accommodated in the bore 2 so that the whole of the air beneath the driving piston is forced into the space 21. The driving piston is made in two relatively movable parts connected by a compression spring which replaces the buffer spring 9.

Title: Method of diffusing impurities into a limited region of a semiconductor body.
IPC: H01L21/22
Filed: 1968-05-31
Abstract: 1,221,882. Semi-conductor devices. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 31 May, 1968 [1 June, 1967], No. 26265/68. Heading H1K. In a process of diffusing impurity into a semiconductor through a hole in a masking layer, an intermediate layer of material in which the impurity diffuses more rapidly than in the semiconductor is disposed between the mask and the semi-conductor. When diffusing indium, gallium or aluminium into germanium silicon nitride and silicon dioxide are suitable for use in the masking and intermediate layers respectively. A PN diode made by diffusing into an oxide coated N-type body through a nitride mask has a high breakdown voltage due to lateral spread of the diffusant through the oxide around the aperture. This spread can be limited by restricting the oxide to a small area surrounding the aperture. A transistor is made from the diode structure by forming an aperture in the oxide after the acceptor diffusion and diffusing donor impurity through it. Alternatively a PN junction isolated transistor can be formed in an N-type body by first diffusing indium through an aperture in a nitride mask to form a P zone 9 (Fig. 7) defined by the area of oxide layer 2 and then diffusing gallium at a higher concentration into the centre of this area to form P + region 8. Finally the base is formed by making a larger hole extending through the nitride and oxide and diffusing donor impurity through it to over-compensate region 5 while leaving region 8 P-type to constitute the emitter.

Abstract: 176,409. Leevers, F. W, Sept. 16, 1920. Wedging or jamming; rotating valves on seats.- Sluice valves having two sliding valve discs are provided with devices for pressing and simultaneously rotating the discs against their seats. Each disc 1, Figs. 1 and 3, is provided with a central boss 3 which engages the inclined surfaces of the wedge 7 carried by the operating-spindle 6. Lugs 8 are formed integral with the wedge 7, and co-operate with eccentric pins 4 carried by the valve discs. The discs are provided with projecting portions 2 which prevent rotation during their downward movement between guides 9, but when the lowest position is reached further movement of the valve spindle causes the wedge 7 to force the discs apart and at the same time the discs are rotated by the pins 4. In opening the valve the wedge member is slightly withdrawn before any rotation takes place, due to the lost motion between the pins 4 and the lugs 8. In a modi. fication, Fig. 4, the projections on the edges of the discs are omitted, and loose stops 10 are substituted to arrest the downward movement. To reduce friction the bosses 3 may be provided with rollers, and to avoid excessive wear the wedge 7 may be formed of or faced with a harder material.
