Title: Improvements in or relating to static electricity machines
IPC: H02N1/04
Filed: 1953-01-23
Abstract: Friction elements and charge carriers for static electricity machines comprise a non-conductive plastic material having admixed therewith a substance having ferro-electric properties in an amount sufficient to increase the dielectric constant of said material, while the internal resistance is maintained at substantially the same value as that of the non-conductive material alone.  The ferro-electric substance may be a titanium compound selected from rutile and the titanates of barium, strontium and magnesium, or a mixture of such titanates, or a binary compound of barium oxide and titanium oxide.  The non-conductive material may be synthetic rubber such as butadiene polymers or copolymers, polyurethane, polyacrylic acid, polyacrylic nitrile, polycaprolactam, polyisobutylene, polyvinyl chloride, polystyrol, and polyethylene.  The compositions may be improved during or after manufacture by orienting the individual particles of the composition, e.g. by vulcanizing the material while under tension.  In examples: (1) threads were obtained by spinning a mixture of polyurethane, polyacrylic acid or polyacrylic nitrile and barium titanate; (2) vulcanized or unvulcanized sheets, strips, plates, rings and ribbons are made from a mixture of polyisobutylene, strontium titanate, carbon black and mineral oil.  The compositions may be spun into fibres and woven, or impregnated or coated on natural or synthetic fibres, including fibres prepared as above, and are then formed into the frictional element or charge carrier.ALSO:A non-conductive composition particularly suitable for use in the manufacture of a frictional element and/or charge carrier for a static electricity machine, comprises a non-conductive plastic material having admixed therewith a substance having ferro-electric properties in an amount sufficient to increase the dielectric constant of said material, while the internal resistance is maintained at substantially the same value as that of the non-conductive material alone.  The ferro-electric substance may be a titanium compound selected from the group consisting of rutile and the titanates of barium, strontium, and magnesium, or a mixture of such titanates or a binary compound or barium oxide and titanium oxide.  The non-conductive material may be natural rubber, synthetic rubber, polyurethane, acetyl cellulose, benzyl cellulose, nitrocellulose, polyacrylic acid, polyacrylic nitrile, polycaprolactam, polyisobutylene, polyvinyl chloride, polystyrol, and polyethylene.  The compositions may be improved by orienting the individual particles of the composition, e.g. by vulcanizing the material while under tension.  In examples, (3) natural rubber was mixed with barium titanate, zinc oxide, sulphur mercaptobenzthiazole and diphenylguanidine, and the mass vulcanized.

Title: Improvements in or relating to golf club shafts and to processes of making the same
IPC: A63B53/02
Filed: 1926-01-26
Abstract: 256,126. White, A. E., (Union Hardware Co.). Jan. 26, 1926. Shafts. - A seamless tubular golf club shaft of smaller diameter at one end than at the other end is formed of low carbon steel and is afterwards carbonized to increase its carbon content, and heat treated and tempered. In making the shaft a cylindrical tube of low carbon steel (about .1 to .45 per cent carbon having a gauge of about .016 inches is rolled or swaged, preferably whilst cold, to a tapered formation the thickness of the wall at the smaller end being thereby increased to about .018 inches. The tube is now carbonized at a comparatively low temperature (about 1450‹ F.) until the steel contains about .6 per cent of carbon and finally the tube is heat-treated, hardened and tempered. The carbonizing and heat-treating processes release the internal stresses and result in the production of a tube having more carbon near the surface than in the interior. For attaching the shaft to the club head the shaft may be formed with an integral enlargement 12, Fig. 1, or may be reinforced by an internal ferrule or plug 13, Fig. 6, or if the socket is larger than the end of the shaft, a ferrule 16, Fig. 7, may be shrunk on to the small end of the shaft.

Title: Improvements in or relating to capping machines for bottles and like receptacles
IPC: B67B3/02
Filed: 1937-01-27
Abstract: 489,500. Bottle capping machines. AKTIEBOLAGET ALKA ALUMINIUMKAPSLAR. Jan. 27, 1937, No. 2405. Convention date, Jan. 28, 1936. [Class 125 (ii)] A bottle-capping machine comprises a cappressing tool or tools and a capping tool or tools mounted side by side on a sledge adapted to receive up-and-down motion, the pressing tools receiving its working motion from the sledge, the capping tool being at least moved to its working position by the sledge, and the sledge being adjustable to various heights according to the height of the bottles. The pressing tools and capping tools may be moved into working position alternately by the motion of the sledge. In the drawings, the pressing tool 5 and capping tool 25 are mounted on the sledge 3 which itself is movably mounted on the standard 2. By means of the shaft 16 driven through suitable mechanism 17 to 22, the cam wheel 12 is rotated, thereby causing up-anddown movement of the bar 13 and the sledge 3, to which bar 13 is attached. The upper part of the pressing tool 4 is fixed to the standard 2 as is also the bottle support 34. The capping tool 25 is operated by the lever 26, draw-bar 28, pin 30 and cam-wheel 31. The cam-wheel is rotated by the shaft 16. The position of the capping tool may be adjusted to suit any size of bottle by raising or lowering the standard 2 on which the sledge 3 is mounted, this being effected by means of the rack and pinion 37, 38. The gear wheel 22 is keyed to the shaft 16 so that the latter may be raised or lowered with the standard 2 without interrupting the drive. In use, the following sequence of operations takes place. The sledge with the bottom half of the pressing tool is raised to form a cap which is blown or otherwise conveyed to the capping tool through the orifice 53. The sledge begins to descend and lowers the capping head over a bottle conveyed to the support 34 by the conveyer 34a. At this moment the draw-bar 28 is pulled inwards by the cam 31, thereby depressing the capping tool 25 and completing the capping of the bottle.
Patent GB-971661-A (GB)
Title: Dioxanes and dioxolanes
IPC: C07D211/22
Filed: 1962-01-23
Abstract: The invention comprises 1, 3-dioxanes and 1, 3-dioxolanes, and their acid addition and quaternary ammonium salts, in which the carbon atom in the 2-position carries at least one carbocyclic or heterocyclic substituent (attached directly or through an alkylene or oxa-alkylene bridge and optionally substituted by one or more halogen atoms or C1-6 alkyl or alkoxy groups) or forms part of a spiro-carbocyclic ring (optionally substituted by one or more halogen atoms or C1-6 alkyl or alkoxy groups) and in which another ring carbon atom carries a piperidyl radical attached directly by one of its ring carbon atoms and optionally substituted on one or more ring carbon atoms by a halogen atom or a C1-6 alkyl or alkoxy group or on the nitrogen atom, e.g. by an alkyl, aralkyl, acyl (e.g. acetyl or diethylaminoacetyl), hydroxyalkyl or dialkylaminoalkyl group, and the preparation thereof by reacting a piperidyl-1, 2-ethanediol or -1, 3-propanediol with an aldehyde, ketone, acetal or ketal having at least one carbocyclic or heterocyclic radical attached (directly or indirectly) to the carbonyl or acetal carbon atom or with a carbocyclic ketone.  When the 2-carbon atom carries only one carbocyclic or heterocyclic substituent, the remaining valency may be satisfied by a hydrogen atom or by an alkyl, alkoxyalkyl or haloalkyl group.  The products are obtained in the form of one or more racemic mixtures, which may be resolved into their optically active antipodes.  Reference is also made to the preparation of some of the compounds by reaction of the appropriate aldehydes or ketones with piperidylethylene oxides, to the introduction of the substituents on the nitrogen atom of the piperidyl radical by alkylation or acylation, and to quaternation with alkyl halides or benzyl chloride.  Piperidylglycols used as starting mateials are prepared by catalytic hydrogenation of the corresponding pyridylglycols.  Pharmaceutical compositions.-The compounds of the invention may be formulated with conventional carriers, e.g. into gels or aqueous solutions, for use in the treatment of gastrointestinal disturbances or as antispasmodic agents.  Some of them may also be used as local anaesthetics, by infiltration or topical application.

Title: Centrifugal fans
IPC: F04D29/30
Filed: 1960-01-25
Abstract: 887,100. Centrifugal fans. WESTING- HOUSE ELECTRIC CORPORATION. Jan. 25, 1960 [Jan. 29, 1959], No. 2585/60. Class 110 (1). Centrifugal fan blades 24, Fig. 1, of aerofoil form are inclined backwardly with respect to the direction of rotation and mounted between a front plate of an impeller and a back plate 20 (or the centre plate in the case of a doubleinlet impeller). A strip 25 of spring metal having a bent-over end 26 is riveted to the pressure face of each blade near the trailing end and can be placed manually into an alternative position in which it lies flush with the pressure face, with the end 26 extending behind the trailing end of the blade. In this alternative position of the strips 25 the fan develops its normal pressure and volume. When the strips 25 are in the position shown, they deflect the flow forwardly in the direction of rotation to increase the capacity of the fan by up to 30% with a slight loss of efficiency. In the blade shown in Fig. 8, a strip 25E is riveted to the suction face of the blade with its bent-over end 26E projecting beyond the pressure face of the blade to increase the capacity. Alternative holes for pins 39 are provided to give a fully retracted position in which the end 26E does not project beyond the pressure face, the pressure then being normal; and an intermediate position in which an intermediate pressure increase is obtained. In a modification, the pins 39 are omitted and the strip 25E has two positions only, the second position being obtained by bracing the end 26E against the suction face of the blade. In a further modification, infinite variation between the two limits is obtained by means of an adjusting screw threaded into the blade and bearing against the strip 25E. An alternative construction comprises a strip, without a bent-over end, riveted to the pressure face of the blade and retractable against its own springiness by means of an adjusting screw into a position flush against the pressure face. In Fig. 7 a strip 29 extending through the pressure and suction faces of the blade has slots 28 to receive adjustment screws 30 whereby the extent of its projection beyond the pressure face can be varied. Specification 841,164 is referred to.

Abstract: 969,153. Cooling dynamo-electric machines. MOTEURS DROUARD. Jan. 22, 1963 [Feb. 2, 1962], No. 2666/63. Heading H2A. In an electric motor pump unit a gap tube separates the stator and rotor, the rotor cavity being initially filled, through a filter, with pumped fluid which does not circulate around the hydraulic circuit so that cooling fins are needed on the outer casing of the motor. Shaft mounted rotor 4 is supported in bearings 9, 10 located in housings 8, 7, respectively. The stainless steel gap tube 6 has flanged ends and is mounted on and sealed to bosses 20, 19 by rings 16, 15. Filter 21, consisting of a sintered metal disc, allows clean fluid to pass through a passage in housing 8 into the rotor cavity, the displaced air being exhausted to atmosphere through bleeder 33 which communicates with the rotor cavity through bore 13 and radial holes 14 in the shaft. In operation the pressure drop across the filter element is large enough to prevent any large quantity of fluid being expelled through bearing sleeve 9 so the same fluid remains within the rotor cavity. The stator cavity is filled with good thermally conductive material e.g. quartz, silica, and casing 34 has both external and internal fins 35, 36. Thrust plate 28 and the bearing sleeves preferably comprise a mixture of sintered bronze and P.T.F.E. so that accidental dry operation of the motor may be permitted. The bearing housing 8 preferably has a heat-proof coating on its inner wall.

Filed: 1957-01-25
Abstract: <PICT:0794329/III/1> In a gas-cooled nuclear reactor the fuel is unenclosed, gaseous fission products being separated from the coolant.  Uranium rods 5 are positioned in a graphite structure 2 and are cooled by carbon dioxide gas under pressure.  This gas is cooled in a steam generator 7 and part of it is forced through a line 26, the remainder returning to the reactor.  The gas drawn off at 26 is further cooled at 28 and passes through a perforated pipe 30 within a closed vessel 31 containing water.  Any gases, particularly xenon, not dissolving in this water are removed at 39, the water and dissolved gas passing through a throttle valve 34 to a low pressure vessel 32 in which degasification occurs.  A pump 36 returns water to the vessel 31 and a compressor 41 returns the carbon dioxide to the reactor, after trapping water vapour in a freezing plant 43.  The purifying process may be continuous or discontinuous.
