Patent GB-456681-A (GB)
Title: Improvements in or connected with devices comprising a cylindrical part which, relative to a mounting, requires to be movable endwise and at one or at more than one position be free to rotate or partially rotate about its axis without movement axially
IPC: G02B7/04
Filed: 1935-07-11
Abstract: 456,681. Optical apparatus. BARR & STROUD, Ltd., STRANG, J. M., and MACGILL, C. D., Caxton Street, Anniesland, Glasgow. July 11, 1935, Nos. 19800/35 and 7296/36. [Class 97 (i)] An optical eyepiece has an eyecap which is axially adjustable on the eyepiece to more than one position relative to the eye lens and has means for retaining it against unintentional axial movement from its selected position of adjustment, release of the eye cap for movement to another position being effected by movement of the eyecap, or of an annular member associated therewith, in a plane normal to the axis of the eyepiece. As shown in Fig. 1 the eyecap B has tongues 2 which engage a three-start screw thread 3, of which each end runs into a circular groove. Thus rotation of the cap with a slight pull causes the tongues to engage the screw thread, thus causing the cap to be moved axially until the tongues engage a second circular groove, when axial movement ceases. Alternatively the grooves may be made slightly deeper than the screw-thread and the cap released by pressure on knurled portions 14, Fig. 7, which causes the tongues 13 to move apart in the direction of the arrows, and allows them to engage the screw thread for axial movement. In a modification shown in Fig. 3, the eyecap comprises two sleeves 5, 6 relatively rotatable to a small extent, a pin 10 on the sleeve 6 engaging an annular groove 12 on the sleeve 5. The sleeves carry. tongues 7, 8 to engage the thread in the barrel A, the tongues being normally held apart by a coiled spring 9 one end of which is connected to the sleeve 5 and the other end to the sleeve 6, so that on rotating the sleeves in opposite directions the tongues 7 and 8 are drawn together as at 7a, 8a, Fig. 5, and register with the screw thread, thus allowing the eyecap to be screwed to the next annular groove 4 where the tongues spring apart and prevent further axial movement. The screwthread may be replaced by a series of axial grooves. Alternatively the tongues may be relatively displaced axially as at 20 and 21, Fig. 12, and may slide in a groove 22 until they reach a slot 23 when they move apart under the action of a spring and by engagement with the slot prevent further axial movement. In a further modification shown in Fig. 8, the eyecap B carries a key 17 which engages a longitudinal keyway 18 at each end of which is a circular groove 19. The outside of the eyecap B engages a screw-thread carried on the inside of a rotatable ring C which also carries a tongue 15 engaging a circular groove 16 in the barrel A. The cap B and eyecap C are rotated until the key 17 engages the keyway 18 when further rotation of the cap C causes the screw-thread to move the eyecap B axially until the key 17 engages the circular groove 19, when axial movement ceases.

Title: Production of gas
IPC: C10L5/00
Filed: 1971-06-09
Abstract: 1399452 Making combustible gas BRITISH GAS CORP 5 June 1972 [9 June 1971 10 June 1971] 19801/71 and 19944/71 Heading C5E The c.v. of a methane-containing primary gas which also contains minor quantities of H 2 , carbon oxides, non-methane paraffinic hydrocarbons and aromatic constituents, is increased by contacting the gas at elevated pressure, e.g. 10 to 100 atmos., and temperature, e.g. a gas exit temperature of 400‹ to 580‹ C., with a hydrogenation catalyst whereby H 2  in the gas reacts with the constituents, non-methane paraffinic hydrocarbons and carbon oxides, to increase the CH 4  content. The primary gas may be made by a non-catalytic hydrogenation process, e.g. in a fluidized bed as in Specification 1,154,321, or by gas recycle, as in Specification 1,031,717, and this gas is passed through a condenser to remove the aromatic constituents and cool the gas to, e.g. 200‹ to 375‹ C., and through a desulphurizer. Alternatively, the cooling may be limited to allow some aromatic constituents to pass a first purification stage for desulphurizing it and then be condensed out, the gas then being subjected to a second purification. Carbon oxides, steam and hydrocarbons may be added to the gas before it enters the catalytic (methanation) stage, e.g. CO 2  removed from the hydrogenating gas passed to the first stage, or benzene recovered from the primary gas. A catalytic hydrogenation stage may precede the methanation stage.

Abstract: 1,052,953. Coated films. B. X. PLASTICS Ltd. May 10, 1963 [May 25, 1962], No. 20121/ 62. Heading B2E. [Also in Division B5] Two orientated thermoplastic film surfaces are sealed by applying a pressure sensitive self-adhesive to each of the surfaces and thereafter pressing the surfaces together. The adhesive may be a "cold seal" adhesive which gives a good joint at room temperature. The seal may be formed at a higher temperature provided that it is less than the temperature at which shrinkage or deterioration of the film takes place. The adhesive is applied by a brush, a roller or by an air knife technique. The seal may be formed by a crimp wheel. The adhesive may comprise natural rubber latex. The adhesive may also comprise a thickening agent, an antioxidant, a wetting agent, a foam suppressor, an alkali sufficient to produce a pH of 9.5-10.0 and tackifying resins. Suitable thickening agents are alginates, soluble cellulose derivatives, e.g. carboxymethyl cellulos and methyl cellulose, casein, ethylene oxide polymers and water soluble acrylates. Suitable tackifying resins are terpene resins, coumaroneindene resins, natural resin and hydrogenated resin. Antiblocking agents, such as polyethylene and paraffin wax, may be added to reduce tack. Tack of the adhesive may also be further controlled by the addition of addition polymer emulsions such as vinyl acetate/ethyl acrylate; styrene/butadiene; and styrene/methyl methacrylate polymer emulsions. Examples are given in which the following substances are also mentioned as ingredients of the adhesive compositions; ammonium hydroxide, a styrenated phenol, sodium di octyl sulphosuccinate, an aliphatic alcohol as antifoaming agent, borax, sodium orthophenyl phenate, and a petroleum/paraffin wax emulsion. The film surfaces may be treated by a corona discharge before the adhesive is applied thereto to increase the adhesion. Alternatively, the film surfaces may be pre-coated with a keying coat, e.g. graft polymers of natural rubber and copolymerizable compounds such as methyl methacrylate, rubbery butadiene/ acrylonitrile copolymers and polyisobutylene. Polystyrene and polyvinyl chloride biaxially orientated films may be sealed by this method. Isotactic polypropylene is disclaimed.
