Title: Improvements in rotary, positive-displacement type liquid meters
IPC: G01F3/06
Filed: 1965-06-14
Abstract: 1,115,674. Rotary liquid meters. A. D. SMITH CORPORATION. June 14,1965 [June 17,1964], No. 25117/65. Heading F1F. A rotary positive displacement liquid meter particularly for measuring petrol, comprises a cylindrical casing 7, Fig. 1, mounting a central non-rotating shaft 13 on which rotates a rotor 16 formed with radial slots 50 slidably mounting blades 46 À À 49, Fig. 2 connected by yokes 51, 52 in diametral pairs disposed at right angles to each other. An inlet 9 to the casing 7 is separated from an outlet 10 by an abutment formed on the casing which closely fits the rotor. A cam-plate 40 fixed to the shaft 13 and engaging cam-followers 55 carried by the rotor moves the blades successively radially outwards into sliding engagement with the casing to trap between adjacent blades a fixed quantity of liquid which is carried to the outlet. A counter 73 connected by a gear train to the rotor 16 indicates the amount of liquid passing through the meter. Upper and lower bearing assemblies 29,19 have inner races keyed to the shaft and outer races to the rotor to permit axial movement of the races but prevent rotary movement thereof with respect to the shaft and rotor. A coil spring 39 abuts the cam-plate 40 and through a collar 41 the inner race 30 of the upper bearing assembly which in turn through a washer 38 abuts a thrust bearing 35 which supports the weight of the rotor and blades. The loading of the spring 39 may be adjusted by a screw 42 and a pin 43 which bears on a cross-pin 44 extending through a slot 45 in the shaft 13. The casing 7 is enclosed with a clearance 11 within a housing 1 having an inlet port 2 connected directly with the inlet 9 and an outlet port 3 connected via the clearance 11 with the outlet port 10 so that the casing 7 is completely surrounded by liquid to prevent distortion of the casing. To prevent accumulation of foreign matter in the bottom of the meter, hoods 78,79 fitted on the bottom plate of the casing 7 direct liquid into and out of a chamber 82 to cause turbulent circulation of the liquid.

Title: Simulated leather
IPC: D06N3/04
Filed: 1975-06-13
Abstract: 1514224 Coated foam-fabric composites ROHM & HAAS CO 13 June 1975 [3 July 1974] 25323/75 Heading B2E [Also in Division B5] A simulated leather comprises a laminate of two or more layers of foam-coated fabric (the term "fabric" including imitation leathers) the laminate having a finishing surface layer and the foam being crushed, i.e. compressed from a greater thickness so that the walls connecting the cells are thin and flexible. The foam is preferably a cross-linkable emulsion copolymer which includes a surfactant for stabilising the foam, and may be dyed or pigmented. The laminate may be made by applying the foamed polymer composition to a fabric and drying the foam at 200-350F so as to ensure mechanical stability without curing. The foam is then crushed, preferably during the lamination of 2-7 fabric layers at 150-300C and at up to 300 psi, and subsequently cured at 135-190F. The finishing layer may be applied as a coating or a preformed film; in the latter case, transfer techniques may be used to apply one or more layers (one of which may be the release coating on a release layer). The finishing layer may be applied as a film during crushing/ laminating and is then cured with and bonded to the foam. If applied as a coating, said layer may be applied to the crushed foam and then cured at room temperature or by heating at up to 100C. The finishing layer may be made porous by mechanical foaming, perforation or temporary fillers and may be metallised, printed, pigmented or dyed. The surface of the laminate may be flat or embossed; embossing may be carried out during lamination or after crushing. Embossed release papers may be used for applying the finishing layer. The specification lists many suitable fabrics, foams and finishes. In examples, the following materials are used; Fabrics: polyester crepe, polyester/cotton fabric, cotton fabric (e.g. twill), rayon challis and acetate tricot; Foams: butyl acrylate/ethyl acrylate/N-methylol acrylamide/itaconic acid and butyl acrylate/ethyl acrylate/acrylonitrile/acrylamide/itaconic acid copolymers which may include melamine resin cross-linking agents; Finishing-films for application by transfer: latices of butyl acrylate/ acrylonitrile or methyl methacrylate/methacrylamide/N-methylol acrylamide/itaconic acid copolymers; Finishing coatings for application by spraying: nitrocellulose/polyetherurethane/ silicone rubber and cellulose acetate butyrate/ polyester/polyurethane solution. Woven fabrics may be laminated with the same or differing orientations, e.g. 45 in Example 6. The non-finished surface of the laminate may be comprised by a synthetic pile fur fabric.

Title: Improvements in or relating to sound records
IPC: G11B3/70
Filed: 1930-08-26
Abstract: Sound records are made of a phenol aldehyde condensation product in which there is incorporated a small amount of soap, for example a quantity which is less than 10 per cent by weight of the phenol employed in the condensation, the soap serving to lubricate the playing surface.  Preferably a water-soluble soap is used, e.g. soft soap prepared from linseed oil and caustic potash and containing a considerable amount of glycerine.  The condensation product may be made from resorcinol and formaldehyde. Plasticizing agents (e.g. glycerol compounds or chlorinated hydrocarbons) and filling materials may be incorporated.  A suitable mixture is specified, made from the following ingredients in stated proportions: resorcinol, formalin, glycerine, silica flour, carbon black, and soft soap.  The soap is added, together with the other components, after the phenol and the formalin have been heated together, at such a stage that it does not enter into the condensation reaction.  After the composition has been hardened by drying, it is subsequently pressed between matrices to impress the sound-grooves, and the final hardening in the press may be accelerated by the addition of an alkali to the mixture.

Filed: 1924-10-28
Abstract: 246,570. Smith, C. S. Oct. 28, 1924. Filters with loose filtering-materials; rotary filters ; electrolytic filters; filtering-media.-Colloidal solutions are prepared by bringing a liquid into contact with layers of electro-positive material and electro-negative material both in a sub-divided state. The liquid is delivered to a cylindrical tank 1 mounted on trunnions 3, 3<1>, through an inlet pipe 4 and after being treated escapes through an outlet pipe 5 passing through the trunnion 3. The tank consists of a number of sections A, A<1> - -, held together by bolts 6. Each section comprises two chambers a, b, each chamber a being filled with an inert filtering material such as a mixture of aluminium and sand and each chamber b being formed in two parts, one of which contains finely divided metal such as aluminium while the other contains an electropositive substance such as crushed carbon. The chambers are separated from each other by porous or perforated screens 7 kept apart by rings or corrugated strips of silica or copper. The end chamber has a number of screens of electronegative metal arranged in its carbon compartment to intensify the electrolytic action on the liquid. The tank, which may be made of metal or of non-conducting material such as glass or porcelain, may be rotated on its trunnions by a crank handle 14 and the outlet end may be raised or lowered. Modifications are described in which the cylindrical tank is mounted on trunnions set transversely to its axis and in which the tank is stationary. An electric current from an outside source may also be passed through the liquid under treatment to increase the electrolytic action. The liquid may pass through inert filtering material after passing through the electrolytic material. As examples of electromagnetic materials aluminium, magnesium, iron or alloys of such metals, copper, mercury, silver, gold and sulphur are mentioned. The liquids treated may be rendered more conductive by the addition of suitable salts such as sodium chloride, ferrous or ferric chloride. The solutions obtained are stated to be particularly suitable for use in preparing medicines, in colouring photographic slides, for boiler water, for ice plants, for preparing salt from brine, or for use in laundries.
