Title: Improvements relating to electrical plug and socket connector devices
Inventor: WEST HAROLD EDWARD WILLIAM
IPC: H01R13/52
Filed: 1955-04-29
Abstract: 770,307. Two-part couplings. ROLLSROYCE, Ltd. April 29, 1955 [April 30, 1954], No. 12684/54. Class 38 (1). The contacts of a plug (or socket) are carried in a synthetic or natural rubber block 17 held in a metal shell 10 by a nut 20 and a collet 19, which co-operates with a tapered part of the block 17 so that tighting of the nut 20 causes compression of block 17 against a shoulder 21, thus effecting a water-tight seal between the block and the pins 16. The plug is secured to a flange 11 by a nut 12 and locking washer 13, a rubber washer 15 serving as a seal. In another embodiment (Fig. 2), the shell is in two parts 22, 23 bolted together and to a flange 24, the tapered surface of block 30 being corrugated and co-operating with the inner tapered surface of part 23.
Patent GB-677672-A (GB)
Title: Improved reciprocable fluid-control valve
IPC: F15B13/04
Filed: 1950-05-23
Abstract: 677,672. Variable-pitch propellers. GENERAL MOTORS CORPORATION. May 23, 1950 [June 8, 1949], No. 12840/50. Class 114. [Also in Group XXIX] A control system for a variable pitch propeller comprises a piston 109 for moving a propeller blade 111, and a piston valve 31 for controlling the piston. The valve is operated by solenoids 7OR, 70L which are energised alternately at a relatively high frequency by a drum 120 rotated at a constant speed by a motor 136 and carrying contact strips 123, 124 connected to the solenoids 7OR, 7OL respectively. A brush 119, completing the circuit between one or other solenoid and a battery 117, wipes the drum which is movable axially through a lever 140. When the brush wipes the centre of the drum, the period of energisation of each solenoid is equal and no resultant movement of the piston takes place. If there is a permanent turning moment on the blade, due, e.g. to the area of the trailing part 150 being larger than the leading part 151, stops may be adjusted on the valve so that the relevant delivery port 13 or 15 to the piston is never fully opened, thus providing a higher pressure on one face of the piston than on the other, to counteract the turning moment. Movement of the drum from the central position will cause resultant movement of the piston. Continued energisation of either solenoid may be effected by a manual switch 134. Specification 677,668 is referred to.

Filed: 1956-04-27
Abstract: Copolymers containing 70 to 30 per cent of vinylidene fluoride and 30 to 70 per cent of hexafluoropropene are made by polymerizing 60 to 15 parts of the fluoride with 40 to 85 parts of the hexafluoropropene at a temperature of at least 85 DEG  C., under autogenous pressure, in the presence of a polymerization catalyst. The reaction is preferably effected in aqueous media in the presence of an emulsifier such as the ammonium salt of omega-hydroperfluoroheptanoic acid.  The catalyst may be dibenzoyl, benzoylacetyl, diethyl, di-tert.-butyl, or hydrogen peroxide, ammonium, potassium, or sodium persulphate, admixed if desired with sodium bisulphite.  The copolymer may be cured by heating with peroxides or polyamines such as hexamethylene diamine, or triethylene or hexamethylene tetramine, or radiations from Cobalt-60, or high energy electrons.  The copolymers may be compounded with conventional curing agents, fillers, reinforcing agents such as furnace black and silicas including esterified silicas.  Films, foils, tapes, and fibres may be made from the copolymers and the compositions may be used as coatings for wires, fabrics, or ceramics, and for the impregnation of felts.

[Class 60] A grindstone &c. is profiled by means of a diamond &c. which is guided by the use of a guide finger moving over a temptate, the effective guiding part of the finger having a shape substantially identical with, or similar to that of the diamond, and the shape being adjusted from time to time in accordance with variations due to wear in the shape of the diamond, &c. The grindstone 3, mounted on a spindle 4 is shaped by a diamond 9 carried by a holder 8 secured to a pin 7, which also carries a main guide finger 10 and an auxiliary finger 11. The pin 7 is rotatably mounted in two cranks 6 rotatable with but slidable on a shaft 5, and the device is moved by a handle 13 to carry the finger 10 over a template 2 in order to shape the stone 3. In order to shape the effective part of the finger 10, the stone is first profiled with the auxiliary finger 11, used as a guide, Fig. 3, and the finger 10 is then shaped from the profiled stone, still using the finger 11 as a guide ; the finger 11 is given a shape substantially identical with that of the diamond, by using the finger 10 as a guide to move the finger 11 over the stone. In another method of shaping the finger, this moves over the flat face of a grindstone, the diamond serving as a guide and moving over a flat face of a template lying in the plane of the stone ; a further method consists in moving the diamond and the finger longitudinally of the spindle 5 across the periphery of the grindstone so that the diamond cuts a groove therein, through which the finger is moved and shaped.
