Patent GB-855424-A (GB)
Title: Reinforced rubbery material and method of preparing same
IPC: C08K5/18
Filed: 1957-06-19
Abstract: Rubbers are reinforced by heating a major amount of a curable rubber with a minor amount of a fine pigment of an inorganic compound containing both silicon and oxygen at a temperature above the normal milling temperature but below its decomposition point for a time sufficient to increase the absorption of the rubber on the surface of the pigment whilst maintaining constant the inherent viscosity of the rubber.  The viscosity constancy is maintained by heating under non-oxidizing conditions or in the presence of a primary polyamine having the amino groups attached to C atoms of an aromatic nucleus, or compounds, e.g. polyisocyanates giving rise to such amines.  The rubber can be natural or synthetic, e.g. diene polymers or copolymers and terpolymers of dienes with e.g. styrene or isobutylene amongst the many listed; polysulphide rubbers, silicone rubbers and the polyester urethanes and the mixtures.  The pigments include various forms of silicas, silicon monoxide and silicates, and they may be augmented by other coloured pigments.  The pigments can also be coated by e.g. silicones, amines or alcohols. Specifications 804,992, 804,993, 804,994 and 807,911 are referred to.

Title: Improvements in or relating to nuclear reactors

Filed: 1963-05-15
Abstract: 1,014,784. Reactors. NUCLEAR POWER PLANT CO. Ltd., and A. E. I. JOHN THOMPSON NUCLEAR ENERGY CO. Ltd., [trading as THE NUCLEAR POWER GROUP]. March 26, 1964 [May 15, 1963], No. 19349/63. Heading G6C. A system for restraining a solid moderator core formed from an assembly of blocks, comprises a first set of structural beams 5 disposed at intervals around the core and extending along the core sides from a coolant inlet face to a coolant outlet face thereof, said beams being free at one extremity and fixed at the other, and a second set of structural beams 6 similarly disposed but having their free ends adjacent the fixed ends of the first set and vice versa, one of said sets of beams supporting the sides of the core and the other supporting a set of circumferential restraining rings 7 spacedly surrounding the core, and temperature compensating means for transmitting forces between the set of beams supporting the sides of the core and the rings, said means permitting relative longitudinal and radial movement of the two sets of beams and relative radial movement of the restraining rings and the beams supporting the core sides. Referring to Fig. 2, the force transmitting means comprises wedges 8, 9, the wedges being tapered in both end and side elevation. By choosing the correct taper for a given station along the core length, a constant minimal gap can be maintained between the wedges for any core temperature. Thus at any wedge position during temperature increase, as the beams 5 move the wedge 8 upwards and outwards, the ring 7 moves downwards (expansion of beam 6) and expands radically outwards. Rollers or balls may be placed between the wedge surfaces. The beams 5 support the core against bursting through a series of beams 11 which are not circumferentially interconnected. In a modification (Fig. 4, not shown), the wedges are replaced by links. The reactor is of the gas cooled graphite moderated type, in a steel or concrete pressure vessel.

Patent GB-935344-A (GB)
Title: Fabrication of massive shaped articles of polytetrafluoroethylene
IPC: B29C43/14
Filed: 1960-06-08
Abstract: Shaped articles are fabricated from polytetrafluoroethylene granular powder by wetting the powder with lubricant, compressing the wetted powder to a preform at a temperature between 50 DEG  and 250 DEG C., drying the preform, compacting the dried preform in a mould having a resilient compacting surface, and sintering the compacted preform. The polytetrafluoroethylene employed is in the form of rough sponge-like particles of supercolloidal dimensions having a total surface area of from 1 to 4 sq.m./gm. as measured by nitrogen adsorption.  The amount of lubricant used should be between 5 and 30% by weight of the dry granular powder. In examples quoted for the manufacture of cup-shaped objects, the lubricants used are chlorobenzene, tetrachloroethylene, carbon tetrachloride, and White Oil No. 30 (a kerosene fraction boiling between 220 DEG  and 243 DEG C.).  In general, the b.p. of the lubricant should be 10 DEG  to 20 DEG C. less than the temperature of the mould in the compressing of the wetted powder.  This compression is carried out under a pressure of 300 to 10,000 lbs./sq. in.  Vents should be provided in the mould for excess lubricant, preferably by employing a mould having one or more porous sections constructed from sintered powdered metals and permeable to the lubricant. The dried preform is compacted in a congruent mould at a pressure of 500 to 5,000 lbs./sq. in. and, preferably, at a temperature equal to that of the wet preforming mould.  This congruent mould should have a lining of vulcanised natural or synthetic rubber. Sintering is effected at a temperature between 350 DEG  and 390 DEG C. and, if necessary, with the preform stretched over a shaping frame to avoid warping.  U.S.A Specification 2,393,967 is referred to.

Abstract: 899,581. Television. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 12, 1959 [June 17, 1958], No. 20209/59. Class 40(3). Video signals relating to the same subject but in a plurality of different standards are generated by scanning the subject with a like plurality of light beams each of which scans in a different one of the standards and has a nature (e.g. spectral range or polarization) such that the light or the signals generated thereby in co-operating photoelectric devices may be readily separated. Fig. I shows one embodiment in which a transparency 1 is scanned by the rasters produced by two flying-spot scanning tubes 2, 3 operating with different scanning standards, tube 2 producing light in the violet or ultraviolet region of the spectrum and tube 3 being provided with a filter 8 passing green light. The latter light is reflected by a colour reflective mirror 11 through the transparency 1 and via a similar mirror 12 to a photo-sensitive device 14 in which signals according to the scanning standard of tube 3 are generated whilst the light from tube 2 is transmitted directly through mirror 11, transparency 1 and mirror 12 to a second photo-sensitive device 13 in which signals are generated according to the scanning standards of tube 2. Fig. 2 shows an embodiment of the invention in which the light produced by the flying-spot tubes 21, 22 operating with different scanning standards is distinguished by different polarizations determined by polarizing elements 27, 28. In this embodiment the subject is a colour transparency 30 the light transmitted through which is separated into the component colours red, green and blue by dichroics 31 and directed via semi-reflecting mirrors on to pairs of photo-sensitive devices 41, 42; 43, 44; 45, 46. One of each of the latter pairs is rendered responsive by means of polarizing elements 35, 37, 39 to light biasing a polarization determined by element 27 and the other of each pair is rendered responsive by means of polarizing elements 36, 38, 40 to light having a polarization determined by element 28, so that the pairs of photosensitive devices each produce signals representative of a different one of the component colours with two different scanning standards. Fig. 3 shows a further embodiment in which light from scanning rasters of different standards, produced by tubes 52, 53 and distinguished by colour by means of filter 58, is reflected by the subject 51 and received by pairs of photo-sensitive devices 61; 63 responsive to light from tube 52 and 62; 64 responsive to light from tube 53 in which video signals corresponding to the two different standards are produced. If the spectral ranges of the light produced by the two tubes overlap a suitable combination of the output signals from the four photo-sensitive devices may be effected to produce each of the two required video signals free from contamination by the other. Specification 480,279 is referred to.

Magnetic instruments.-A device for converting electrical impulses into sound or vice versa comprises an armature in the form of a hollow member of oval cross-section having a slot along one of its wider sides formed by folding over a piece of sheet metal so that its opposite edges nearly meet. The armature is preferably so mounted that it rotates about an axis near its centre of mass.
