Title: Improvements in and relating to the compounding of latex mixtures
IPC: C08J3/215
Filed: 1939-05-10
Abstract: 529,246. Rubber latex. BRITISH RUBBER PRODUCERS' RESEARCH ASSOCIATION, MARTIN, G., and WREN, W. G. May 10, 1939, No. 13944. [Class 70] Rubber in latex is compounded by first adding to the latex a stabilizer in the form of an amphoteric colloid or a soap conferring on the rubber globules basic properties or a negative charge when the compounding ingredients are acidic in character and vice versa when the compounding ingredients are basic in character, and then treating the stabilized latex with the compounding ingredients in the form of a hydrophilic dispersion which sets to a gel dispersed evenly throughout the body of the latex. If the latex is stabilized with casein an aqueous sol of silicic acid or aluminium hydroxide gel may be added. If an anionic soap such as oleyl methyl taurine is used, an acidic gel such as silica gel is added, but if a cationic soap, such as cetyl pyridinium bromide, or sulphonium, phosphonium or quaternary ammonium compounds is used an aluminium hydroxide gel is used. In examples, ethyl silicate or other organic silicon compound which is hydrolyzed by water to form a hydrophilic dispersion of silicic acid is used to obtain a silica gel. A composition suitable for making flooring material contains latex, casein solution, ethyl silicate, vulcanizing ingredients and hydrated lime or Portland cement. A flooring material is also made by treating ammonia-preserved latex with sufficient formaldehyde to combine with the ammonia, stabilizing with an aqueous dispersion of gelatine and compounding with magnesium oxide-magnesium chloride or zinc oxide-zinc chloride mixtures. A composition suitable for making dipped goods or impregnating contains latex, casein solution, sodium metasilicate solution, vulcanizing ingredients and antioxidants. A former is dipped into this liquid and then into a solution of acetic acid or ammonium carbonate.

Title: Improvements in or relating to gas discharge apparatus for producing thermonuclear reactions
Inventor: THOMSON GEORGE PAGET
IPC: H05H1/18
Filed: 1946-05-08
Abstract: 817,681. Nuclear fision reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 8, 1947 [April 28, 1946], No. 13963/46. Class 39(4). A thermo-nuclear reactor comprises a toroidal vessel containing a fuel gas at low density, and means for establishing and maintaining a continuous motion of electrons around the toroid. Fig. 1 shows a horizontal sectional view of the reactor. In a steady state an electron current of about 500,000 amps circulates round the toroidal vessel and is maintained in equilibrium partly by its own magnetic field and partly by a magnetic field of about 1500 gauss applied perpendicular to the plane of Fig. 1. The electron current produces a potential of about 500,000 volts, so that denterium introduced through inlet ports 3 is ionised and accelerated to the centre of the toroid where it is further ionised to produce electrons for maintaining the electron current and denterons which undergo fision reactions. Ions which succeed in escaping to the walls of the toroid pass through apertures 7 to an outer vessel and are pumped away through outlet ports 4. The energy required to accelerate the electrons is supplied by electromagnetic waves of 10 cm. wavelength which are fed to the toroid through windows 9 spaced a quarter of a wavelength apart and generate a progressive wave in the ionised gas. The density of the dentrons in the toroid may be 2À4 x 1014 per c.c. giving an energy output of 3,800 k.W., which may be removed by a cooling jacket surrounding the reactor, and a neutron output of 1À9 x 10<SP>19</SP> per second which may be used for irradiation purposes, e.g. making plutonium. Fig. 3 shows the construction of parts of the toroidal vessel. The metal pipe 12 constitutes the outer boundary of the water cooling jacket within which are assembled a series of similar overlapping metal bodies each having firstly a portion 14 serving as part of the reaction vessel and provided with slots 7, secondly a portion 16 of larger diameter extending from the end of the first portion and terminating in a circular flange 17 and an exhaust pipe 18 constituting the outlet port 4 of Fig. 1, and thirdly a shoulder portion 19 joining portions 14, 16 and drilled to provide inlet passages 20 which constitute the inlet ports of Fig. 1. The flanges 17 butt against the shoulders 19 of adjacent members, gaskets being provided to seal the joints. The reaction vessel is preferably of aluminium, but may be of copper provided with an internal coating of aluminium or aluminium oxide, and is arranged in a magnetic field, which may be increased from a low value up to about 1500 gauss as the toroidal current grows, the magnetic field being normal to the plane of the toroid.

Abstract: 1466110 Coaxial cables LIGNES TELEGRAPHIQUES ET TELEPHONIQUES 29 March 1974 [4 April 1973] 14151/74 Heading H1A [Also in Division B3] A method of making a coaxial cable comprises moulding dielectric disc spacers on the inner conductor, wrapping a transversely corrugated dielectric tape with overlap around the inner conductor and the spacers on it, forming a metal strip around the dielectric tape and longitudinally welding the strip edges together and drawing down the cable so formed. Wire is drawn from a reel 11 by a pulling drum 15 through a die 12, which is provided with lubricating and cleaning means 13, 14. The disc spacers are moulded on the wire in a machine 21 and the mould halves are carried on two chains, which are driven by a chain and sprocket wheel assembly 22, 23. The spacing and shape of the discs is monitored by a device 27. The speed of the moulding machine drive motor 26 is controlled by a circuit 28 which receives signals from a generator 54 coupled to a motor 56 of a cable pulling station 7 and from a photo-electric device 29 for monitoring a supply loop of the wire and discs. Insulating tape is corrugated between rolls 32, 32<SP>1</SP> and passed over a guide roll 34 pivotally mounted on an arm 35. The arm is coupled to a potentiometer 36 by pinions (35<SP>1</SP>), (36<SP>1</SP>), Fig. 2 (not shown), to regulate the speed of a motor 37 which drives the roll 32<SP>1</SP>. The corrugated tape is shaped over the disc spacers in a gap between a guide 41 and a cylindrical member 61 concentric with the guide. The edges of the tape overlap but they are not secured together. The metal strip is formed around the corrugated tape and welded by conventional apparatus 43, 44. The welded cable is cooled in a cylindrical enclosure 45 connected to a water circulation system and dried by being passed through an apertured coil 46 which directs compressed air on the cable, Fig. 3 (not shown). The dried cable is drawn through a die 47 by a pulling chain 51 driven by the motor 56 and finally wound on to a drum 52.

Abstract: 311,817. Westinghouse Electric & Manufacturing Co., (Assignees of Landon, V. D.) May 17, 1928, [Convention date]. Right to Patent relinquished. Thermionic amplifiers.-In a radio frequency multi-valve amplifier at least one of the valve plate circuits is arranged to have a capacitative reactance considered alone, whilst when coupled to the tunable input circuit of the following valve the plate circuit has a resistance characteristic. The Figure shows a three-stage amplifier in which the valves 2, 3, 4 are coupled by transformers having dual primaries consisting of a small primary 17 and a larger primary 18 shunted by a condenser 22 and resonant at a lower frequency than that at which the amplifier is adapted to operate. The coupling between the valves 2, 3 is preferably such that the plate circuit is always capacitative and the consequent damping to the input of the valve 2 is compensated by the regenerative circuit 15, 16. To prevent the plate circuit of the detector 4 from being capacitative an inductance 33 is preferably included to avoid damping the detector input circuit. The input valve 1 is preferably resistance coupled to the aerial so that the characteristics of the aerial .circuit do not affect the tuning and all the tuning condensers may be coupled together. Specification 119,365 is referred to.

Abstract: 665,772. Cooling bearings. BRITISH THOMSON-HOUSTON CO., Ltd. June 8, 1949 [June 15, 1948], No. 15296/49. Class 12 (i). [Also in Group XXXV] In a dynamo-electric machine having a rotor 1 mounted on a shaft 3 which is supported by a bearing 12, cooling fluid is circulated so as to provide two heat dams whereby heat from the rotor is abstracted before reaching the bearing. In the water-in-the-gap type dynamometer shown, the cooling fluid enters through a pipe 19 from which some flows through passages 22, 24 to the external surface 4 of the rotor 1, and the remainder flows through passages 23, 29 to an annular passage 28 surrounding the bearing housing, which provides one heat dam. A passage 32 leads the fluid from the passage 28 to a recess 34 provided at the end of the rotor 1, where the fluid forms a second heat dam. From this second heat dam the fluid is pumped by rotation of the shaft 3 and rotor 1 into an end space 26 from which it is exhausted with the heated fluid from the gap 6 through outlets 27. A baffle 35 is positioned adjacent the outlet to the passage 35 to direct the cool fluid on to the shaft. In a modification, shown in Fig. 2, the annular passage 28 is omitted and the cooling fluid directed from passage 29 through passage 32 to the space 34.
