Title: Improvements in or relating to electric insulators
Inventor: DEY PHANIBHUSAN
IPC: H01B17/20
Filed: 1959-10-07
Abstract: 921,933. Insulators. BRITISH INSULATED CALLENDER'S CONSTRUCTION CO. Ltd., and BRITISH INSULATED CALLENDER'S CABLES Ltd. Oct. 7, 1960 [Oct. 7, 1959], No. 34039/59. Addition to 813,818. Class 36. A porcelain or glass pin-type insulator comprises a spindle of a thermo-setting or cold-setting resin containing a finely divided filler. The spindle 7 of a porcelain or glass insulator 1 is vacuum cast from epoxy resin complete with shreds 8 and a metal insert 9 which is internally threaded. The pin 7 and body 1 are joined by an epoxy resin cement. The pin 7 may be reinforced with resin-bonded glass fibre rods arranged in a circle, by a similar glass fibre tube or by a single central rod which projects beyond the base of the pin 7, a screw-fitting being attached to this projecting end by means of a compression joint as described in Specification 816,926. The fillers employed are silica powder and a filler which reduces surface tracking, such as aluminium hydroxide. The resin is preferably an epoxy resin made by reacting an epihalohydrin with a bis-phenol, e.g. that sold under the Registered Trade Mark " Araldite " as "Araldite B." The cast resin form may be hollow and house protective devices, as in the parent Specification.

Patent GB-410875-A (GB)
Title: Process for the preparation of unvulcanised indiarubber in granular form
IPC: C08C3/00
Filed: 1932-12-02
Abstract: Unvulcanized rubber is reduced to granular form by a process which comprises swelling the rubber by soaking it in a dilute aqueous solution of ammonia, and then subjecting it to mechanical disintegration.  In a preferred form of the invention the rubber is soaked and then passed through tightly closed grinding rolls with a little zinc stearate until it is in the form of a coarse powder.  It is finally passed through a disintegrator consisting of rapidly revolving bars which force the coarse crumb through a fine sieve. The crumb is then air dried.  The granular rubber can be mixed with hydraulic cements, or with moulding powders, asphaltum, or oxidized oils either in the dispersed or undispersed form, to increase the elasticity of these materials, or with latex, and moulded under pressure to produce compact or spongy materials according to the degree of pressure applied, or mixed without mastication with cork, fibre, leather dust, sawdust or other organic material, or mixed without mastication with mineral or organic powders, vulcanizing ingredients and colouring material.  The compounded and coloured rubber powder may be used to obtain mottled effects, or differently coloured granulated rubber powders may be distributed unevenly over the surface of unvulcanized rubber to obtain mixed colours, or the coloured rubber powder may be distributed on unvulcanized rubber to obtain definite geometric patterns.  Specification 391,309 is referred to.  The Provisional Specification refers to the swelling agent as a dilute alkali such as ammonia.

Abstract: 944,504. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. March 21, 1960 [March 23, 1959], No. 34407/63. Divided out of 944,502. Heading B7K. The subject matter of this Specification, which is concerned with means for varying the position of the centre of pressure of a supporting air cushion relative to the vertical axis through the centre of gravity of a vehicle, as described with reference to Figs. 1-5 is substantially the same as the equivalent matter described in Specification 944,502. Apparatus for displacing a fluid curtain, and thereby the centre of pressure of a cushion, comprises a slidable flat plate 72, Fig. 6a, having a narrow port 73 mounted over a wide opening in the base of the vehicle. In Fig. 7a the jet curtain passes through an annular nozzle 76 which may be flexible or constructed as a series of separate nozzles, the walls of the nozzle being adjustable about pivots 78, 79 to vary the lateral inclination of the jet. Since a vertical curtain will be weaker than an inclined one, provision may be made to widen the nozzle as it rotates. Specifications 854,211, 893,715, 894,644, 895,341 and 944,503 also are referred to.

[Class 97 (i).] Colour-testing apparatus comprises a doubleimage prism arranged to superpose virtually and present to the eye two differently-coloured images so that an optical mixture of the colours is obtained. If a disc D having a central aperture A is observed through a double-image prism P two images Al, A2 are seen which can be caused to revolve about the axis OA by turning the prism about this axis. If two discs are observed, having apertures covered with say a red colour filter R, and a green filter G, four images R1, R2, G1, G2 are in general observed and by suitable adjustment of the prism by rotation and displacement along the axis, two of the images, e.g. R1 and G2 can be brought into superposition so as to present to the eye the effect of the optical summation of the two colours. The apparatus is used for determining the suitability of given filters for use in colour kinematography with different sources of light.

Patent GB-1026998-A (GB)
Title: Improvements in plaster
IPC: C04B11/26
Filed: 1964-08-25
Abstract: Calcium sulphate "plaster" is prepared from calcium sulphate dihydrate by a process comprising the compression of the dihydrate before or after calcination, to 10,000 to 200,000 lb./ins.2, e.g. 10,000 to 40,000 lb./ins.2. "Plaster" is defined as both calcium sulphate having approximately half a mole of water per mole of sulphate as well as soluble anhydrite CaSO4.XH2O where X may be from nearly 0 to 0.65.  The dehydrate may be a by-product, e.g. from the decomposition of calcium phosphate with sulphuric acid and from the desulphating of bitterns, or naturally occurring wind-blown gypsum. The calcination is carried out by heating at 110 DEG  C. rising to 180 DEG  C. over 2 hours and the compression may be effected intermittently by means of a plunger reciprocating within a passage of diminishing cross-section or by means of rotating parallel rollers, in which latter case the compression may be a two-stage process.

Title: Improvements in and relating to a device for rendering the fuze of a spinning missile safe during flight
IPC: F42C15/285
Filed: 1959-10-19
Abstract: 923,561. Projectile fuzes. ETABLISSEMENTS VALERCA. Oct. 19, 1959 [Oct. 20, 1958; July 3, 1959], No. 35312/59. Class 9 (1). A percussion fuze for rotated projectiles comprises a body 10 in which a striker is held away from a primer 13 by balls 12, a transversely slidable bolt 28 being provided to prevent premature arming of the fuze. A cylindrical housing 20 is rigidly held between plugs 16, 17, screwed into the body 10, and is closed by annular members 21, 22, which support a tube 23 surrounding the striker 11. The annulus 21 has a flange 26 bearing against a collar 25 integral with the tube 23, which tube forms the spindle of a wheel 34 having an upstanding rim 35. On the collar 25 is a ridge 32 having a spiral cam surface leading to a port 33 and housing balls 31. Transverse movement of the slide 28 is prevented by a nut 29 screwed on the wheel shaft 36 and having a longitudinal slot 40 engaged by a screw 39, which constrains the nut to move longitudinally along the shaft when the wheel rotates. During transport the fuze parts are locked by a split ring 45 housed in a groove in the cylinder and having a nose 45a engaged in the wheel rim. This ring also determines the starting position of the wheel. Co-planar with the port 33 are openings 38 in the rim and a port or ports 42 in the cylinder 20, whose inner surface, in the vicinity of the port 42, has a cam slope 41. When the projectile is fired, the centrifugal force produced causes the ring 45 to move outwardly and release the wheel 34. Under centrifugal force, the balls 31 move along the cam surface 32a to the port 33. A ball 31 entering the port presses against the cam slope 41 and a resultant tangential thrust is transmitted to the wheel, causing the wheel to rotate until the ball 31 escapes through the port 42. A second ball 31 then enters the port 33 and rotates the wheel a step further, at the same time shifting the nut 29 axially. When the wheel has rotated sufficiently to move the nut a predetermined amount, the bolt 28 is freed and moves radially until a notch 28a is aligned with the striker, the fuze then being ready to operate. The port 33 may be wide enough to accommodate two balls 31 simultaneously, or three ports 33, equally spaced and each associated with a cam surface 32a, may be provided. The bolt 28 may be secured by a member 49 forming part of the wheel, which is in two sections 49, 51, Figs. 6 and 7 (not shown). Within the section 51 is an annulus 53 integral with the tube 23 and fixed by a screw 55. Cam surfaces 32a guide the balls 31 to the ports 33 as before.
