Filed: 1974-07-25
Abstract: 1516304 Measuring surface drainage DUNLOP Ltd 24 Oct 1975 [25 July 1974] 32956/74 Heading G1S A meter for measuring the drainage characteristics of a surface such as a road comprises an elliptical disc 14 (e.g. of rubber) which is pressed into contact with the surface by a weight 17. A circular or elliptical orifice 15 through the disc is supplied with liquid from a reservoir 11 and the time required for the outflow of a given volume may be obtained by observing the change of level through transparent walls of the reservoir or from visual signals initiated by circuits connected to electrodes 18, 19. The electrodes are attached to an upper plate 20 which may be rotated relative to a lower plate 28 and the disc 14 so that the electrodes correctly indicate the change of level when the meter is used on a sloping surface. By using an elliptical disc the meter may detect anisotropy in the drainage characteristics due for example to parallel grooves 21 in the surface.

Filed: 1936-06-02
Abstract: Compositions for impregnating, finishing, stiffening, or sticking fibrous materials to obtain waterproof products comprise aqueous emulsions containing polymerized vinyl compounds and an aluminium salt of a fatty acid, such as aluminium oleate or stearate.  Suitable synthetic resins include polyvinyl esters, acrylic acid esters, mixed polymerizates of these esters, vinyl ethers and/or vinylbenzene hydrocarbons, vinyl ketones and the mixed polymerizates from vinyl ketones and the above esters, ethers or hydrocarbons.  The compositions may be made by adding the aluminium salt to the emulsion of the polymeride; emulsifying together the polymeride and the aluminium salt or polymerizing the vinyl compound in the presence of the aluminium salt. According to examples: (1) a polyvinyl butyrate emulsion prepared according to Specification 466,173 is stirred with a solution of aluminium stearate in toluene; (2) a mixture of vinyl chloride and vinyl acetate is polymerized as an aqueous emulsion and stirred with phthalic acid diamyl ester and a solution of aluminium stearate in tetrachlormethane.  The product gives waterproof elastic finishes.  The products are used in the finishing and stiffening of felt hats and hats made from straw, regenerated cellulose, bast fibre or artificial silk; for the waterproof impregnation of textile fabrics and plaited materials and for sticking together textile materials.

Title: High temperature separation of straight chain hydrocarbons
IPC: C10G25/03
Filed: 1958-10-24
Abstract: The separation of straight-chain hydrocarbons from branched chain and/or cyclic hydrocarbons present in the effluent from a conversion process and at a temperature of at least 300 DEG  F. is effected with a molecular sieve at a temperature of 300-800 DEG  F. Regeneration of the sieve is then effected without change in temperature by reducing the pressure or using a purge gas such as nitrogen, hydrogen or hydrogen-containing gas, e.g. reformer recycle gas.  Suitable reaction effluents which can be treated are those from polyforming, thermal or catalytic reforming, thermal cracking, coking, polymerization, alkylation or isomerization reactions.  The sieve preferably has a 4-5   pore size.

Abstract: 169,923. Carver, T. A. B. Dec. 8, 1920. Feeding webs.-Relates to the feeding of a long band to a consuming-apparatus, such as a kinematograph mechanism or a jacquard machine. The band is folded at equal intervals along its length alternately in opposite directions to form a stack of flat layers, and the stack is so supported that the folds at either side are freed alternately as the band is fed to the consuming-apparatus. The stack rests on a floor formed by two sets of slats so hinged as to form aprons d, e, transversely flexible in one direction, and the band passes through the gap c between the aprons. The free ends of the aprons pass over rollers f, g carried by a bracket h which is adapted to reciprocate in guides to cause the gap c to shift from side to side as the band is withdrawn. The reciprocation may be effected by the pull of the band or by mechanism in synchronism with the consuming-apparatus.

V-shaped transverse supports 16 partially support the material over a scraper conveyer in the bottom of a bunker which has pendant sides 8 which can be reciprocated at their lower ends to cause the material to fall on to the conveyer. As described, the sides 8 are hinged to the tops of uprights 1 and are reciprocated by pneumatic rams 12. Three transverse supports are mounted on horizontal plates 10 which overlap the sides of the scraper conveyer. The doors are reciprocated to dislodge adherent material much of the weight of which is borne by the transverse supports. Any material which falls between the sides of the bunker and the ends of the supports is forced into the inside of the supports and down on to the conveyer, the bevelled edges of plates 10 and stiffening members 18, 19 chopping the material up into blocks.

Abstract: 777,071. Spindle drag devices. FAIRBAIRN LAWSON COMBE BARBOUR, Ltd. Oct. 19, 1955 [Dec. 3, 1954], No. 35016/54. Class 120 (2). In a textile spinning machine in which yarn is wound on to a bobbin by a flyer, the bobbin being caused to rotate by the tension in the yarn, the bobbin is provided with a support having a friction coupling to a seating which is connected to the flyer driving means by a positive drive, which causes or allows rotation of the seating at a lower rate than that of the associated bobbin. In the arrangement shown, the flyer 1 is driven from a pulley 2 from a main drive shaft 28. The bobbin 3 is mounted on a support 5 which slides on a "dead" spindle (not shown) fixed to the lifter rail 4. The support 5 rests on a facing 6 of suitable material fixed on a brake seating 7 which is rotated by a pair of spiral gears 9 from a shaft 11. The shaft 11 is driven through a clutch 19, bevel wheels 20, shaft 22, bevel wheels 26, shaft 27, and "change" gear 29 from the shaft 28. The drives are arranged so that the speed of rotation of the seating 7 is less than that of the bobbin 3 so as to produce a " drag " thereon. Rotation of the seating 7 reduces the power required from the shaft, 28. For bobbin doffing the handle 16 is moved to the right thus disengaging the dowels 17 from the gear box 18 and also disengaging the clutch 19, enabling the sail 4 to be lowered to the doffing position.
