Title: Method of checking the creeping of cores within the sheaths of electric cables
Inventor: DEERING JOHN EDWARD
IPC: H02G15/117
Filed: 1948-07-05
Abstract: 721,662. Electric cables; cable joints. POSTMASTER GENERAL. Nov. 29, 1950 [July 5, 1948], No. 18074/48. Classes 36 and 38 (1). Electric conductors are prevented from creeping within the sheath of an electric cable 10 by removing part of the sheath to expose the core 11, enclosing adjacent portions of the sheath 10a and exposed core 11 within a hot plastic mass of polyethylene 12, and allowing the mass to cool and shrink to form a muff on the enclosed parts. A plug of polyethylene may be inserted between the insulated conductors to form an enlargement of the core and improve the grip of the muff thereon. This plug also becomes fused with the muff. When a cable joint 14, Fig. 5, is made the enclosing lead sleeve is applied in two parts. Part 16 is plumbed to the cable sheath and filled with a hot plastic mass 17 of polyethylene. The other part 15 is plumbed to the lead sheath at 15a on the other side of the joint, and the two parts are plumbed together at 15c. Instead of polyethylene another thermoplastic organic insulating material having similar physical properties may be used. Specification 721,664, [Group V], is referred to.

Title: Improvements in or relating to hydrostatic transmissions
Inventor: PEARSON ROBERT COLIN
IPC: B62D11/18
Filed: 1961-05-18
Abstract: 941,735. Motor vehicle hydraulic steering and driving gear. R. C. PEARSON. Feb. 12, 1962 [May 18, 1961], No. 18238/61. Heading B7H. [Also in Division F2] In an hydrostatic transmission, for a wheeled or tracked vehicle, comprising a pump or pump set 2 supplying two variable displacement motors or motor sets 21, 22 in parallel, each controlled by an hydraulic jack 30 or 31 responsive to pressure in the high pressure fluid supply line above a predetermined pressure, steering control is effected by reducing the effect of the hydraulic pressure on one jack to reduce the displacement of the corresponding motor. Prime mover 1 drives reversible pump 2 with interchangeable supply and return lines 15, 16 to the motors, boost pump 3 supplying pump servo control valve 5 and the required minimum pressure to jacks 30, 31 through line 13 and pump 4 maintaining the fluid circuit full. Shuttle or equivalent valves 41 and 60 respectively maintain line 42 at the higher pressure of lines 15 and 16, and the inlet ports 108, 109 of steering valve 45 at the higher pressure of lines 13 and 42. In the neutral position of steering valve 45 this high fluid pressure is supplied through lines 48, 49, change-over valve 50 and lines 142, 143 to the jacks 30, 31. The positions of the pistons 34 which have damping holes 36 is determined by the balance of the fluid pressure on the larger area side of the piston on the one hand and the spring load and fluid pressure on the smaller piston rod side of the piston on the other hand. Increase in line pressure moves the pistons to increase the motor displacement. Downward movement of lever 43 to steer the vehicle moves frame 47 and valve spool 44 downwards when first pressure port 109 is cut off from line 48 by land 120 and then line 48 and jack 30 are connected with outlet port 110 and hence line 14 and reservoir 11. The resulting reduction in pressure in jack 30 allows the spring to move the piston to reduce the motor displacement. " Feel " is provided at lever 43 by springs 63, 64 and the difference in pressures in chambers 152, 153 acting on the spool 44, the chambers 152, 153 communicating through passages 150, 151 with the lines 48, 49. Change-over valve 50 is connected between lines 15, 16 so that when the pressure differential between lines 15, 16 is reversed, as when the transmission changes from the drive condition to the over-run condition, the connections between lines 48, 49 and the jacks are reversed so that the steering effect is not reversed. Specifications 902,185 and 941,737 are referred to.

Title: Improvements in or relating to processes for the production of semi-conductor arrangements
IPC: H01L29/78
Filed: 1960-05-24
Abstract: 937,497. Semi-conductor devices. SIEMENSSCHUCKERTWERKE A.G. May 24, 1960 [May 28, 1959], No. 18321/60. Class 37. Alloying between a semi-conductor body and a body of electrode material to form a junction between doped semi-conductor zones having different types of conduction or the same type of conduction but different degrees of doping is carried out with a rising temperature gradient exceeding 20‹ C. per minute and preferably exceeding 50 C.‹ per minute. The Specification states that with semi-conductor bodies cut along the (111) plane the junction is often of undulating or stepped form caused by the anisotropy of the crystal lattice but that the anisotropy cannot take effect if the alloying is sufficiently rapid. It is also stated that wetting difficulties between the (111) plane and the wetting electrode metal may be obviated by cutting the semi-conductor deliberately deviating from this plane. The heating process of the invention thus gives a regular surface at the junction. The Specification refers to the manufacture of junction rectifiers and transistors by this method and to the use of germanium and silicon but explains that the invention is not limited to materials whose plane of greatest energy stability is the (111) direction.

Abstract: 780,455. Semi-conductor devices. SIEMENS & HALSKE AKT.-GES. June 28, 1955 [July 6, 1954], No. 18645/55. Drawings to Specification. Class 37. One conductivity type zone of a PN junction is produced by adding to the zone, at least two donors, or at least two acceptors, having different speeds of diffusion and/or distribution coefficients. By this means a graded PN junction may be produced in contrast to one having a steep rate of change of impurity. The graded junction may form the collector electrode of a junction transistor. In an example, arsenic and lithium as donor materials, with or without neutral materials such as lead, tin or gold, are diffused into the surface of a P-type germanium body to form a graded junction, while a steep junction is produced on the opposite surface by diffusion of arsenic alone. Specification 764,489 is referred to.
