Abstract: 897,013. Assembling force fits. HOLMAN BROS. Ltd. Dec. 12, 1960 [Sept. 11, 1959], No. 31135/59. Class 83 (4). A pair of members, used in e.g. a gas-turbine or supercharger, are provided with locating means which comprises a spigot carried by one member and adapted to be engaged within a socket afforded by the other member, the spigot and the socket having circumferential mating surfaces which are an interference fit one within the other, and in which the spigot and/or the socket is of tubular form and is formed at its outer end with a head providing the mating surface and, between its inner end and the head, with a neck portion of substantially less wall thickness than that of the head, the neck portion affording a region of increased flexibility. In an embodiment a member 1 is provided with a spigot 3 which is a force fit within a necked tubular socket 4 formed integrally with a member 2, Fig. 1. The surface 5 of the spigot 3 is provided with a fine taper and a groove 10 is formed around the spigot base. In another embodiment the socket 11 is formed as a cylindrical recess in the member 1, Fig. 2, and the member 2 carries a necked protruding tube constituting the spigot 12. The base of the socket is formed with a groove 20 and the rim of the socket is chamfered as at 19. The member 2 may be undercut as at 21, 22 at the root of the spigot to increase the effective length of the neck 13 without increasing the overall distance by which the spigot protrudes from the part 2. Transverse mating faces (not shown) are provided on the spigot or socket or on the members 1 or 2 in order to maintain axial location and squareness of the members which are finally held together by bolts.

Patent GB-798186-A (GB)
Title: Improvements relating to resinous products prepared from aluminium alcoholate derivatives
IPC: C08G79/10
Filed: 1954-11-02
Abstract: Resinous products capable of forming films in air are obtained by reacting aluminium alcoholates having alkoxy groups with 3 or 4 carbon atoms with glycols having 6 or more carbon atoms and reacting the resulting products with drying or non-drying fatty acids. Aluminium alcoholates specified are the isopropoxide, sec.-butoxide, di-isopropoxide monoisobutoixde and the di-sec.-butoxide monoisopropoxide.  Glycols mentioned are hexylene, octylene and dipropylene glycol.  Suitable fatty acids are those of linseed oil, dehydrated castor oil, tobacco seed oil, tung oil, or soya bean oil. The products in solution give coating compositions.  Pigments or fillers may be included.  In the examples: (1) octylene glycol was added to a white spirit solution of aluminium isopropoxide and the mixture distilled in vacuo to remove isopropanol and some white spirit.  To the resulting clear solution linseed oil fatty acids are added and distillation resumed.  Addition of more white spirit and fatty acids yielded a solution which dried in air to a hard film. The other examples are similar, employing the following ingredients: (2) aluminium tri-sec.-butoxide, octylene glycol and dehydrated castor oil fatty acids; (3) aluminium tri-sec.-butoxide, dipropylene glycol and stearic acid; (4) aluminium di - sec.-butoxide-mono-isopropoxide, dipropylene glycol and stearic acid. Tendencies of certain products to gel can be overcome by the use of gel cutters, e.g. isobutanol or ethyl "Cellosolve" (Registered Trade Mark), in place of some of the white spirit.  Preferably the aluminium alkoxide and the glycol are mixed at low temperatures, e.g. 0-5 DEG  C.  Reference has been directed by the Comptroller to Specification 772,144.

The noble gas, which may be helium, argon, krypton or xenon is excited by electron collisions to a metastable state which corresponds to one of the excited states of the nitrogen molecule. The output frequency, which lies in the ultra-violet part of the spectrum, depends upon the excited state which is utilized, which in turn depends upon the choice of noble gas. The gases are maintained at 10 to 500 mms. Hg. in a discharge tube having a diameter of between 1 and 30 mms.

Title: Textured coatings

Filed: 1974-07-18
Abstract: 1472887 Textured coatings BERGER JENSON & NICHOLSON Ltd 18 July 1974 [18 July 1973] 31977/74 Heading C4A [Also in Division C3] A substrate having a textured coating is produced by applying on to the substrate a textured paint which is substantially free from binding pigments. A " textured paint" is a paint which is either thixotropic or of high viscosity such that when applied to a substrate by spraying or spattering the effective viscosity is sufficiently high to prevent efficient atomization so that the paint is applied as irregularly sized blobs which harden to form a textured surface. The term " binding pigments " means substantially opaque and often coloured material added to the base in relatively large quantities to hide the surface being coated and often also to colour the paint. Thus the term excludes materials such as silica and bentonite clay, added in small quantities as extenders, binders, thixotropic agents and/or flatting agents. In the examples the textured paints comprise SiO 2 , bentonite clay, short-oil air drying alkyd resin, ethylene glycol, hydrocarbon solvent, silicon, oil, ketoxime, Co/Pb/Mn octoate drier, tung oil, nitrocellulose, short-oil, non-drying alkyd resin, short-oil, semi-drying alkyd resin, ketone resin, urea resin, plasticizer, xylene, butyl acetate, diacetone alcohol, ethylene glycol, isobutanol, a solvent mixture of lower alkyl acetates, emulsifier, polyethylene wax, vinyl chloride copolymer, P.V.C. stabilizer solution, an acrylate resin containing hydroxyl groups, ethylene glycol acetate and a polyisocyanate cross-linking agent.

Preferably parallel carbon fibres are placed in the mould, impregnated with epoxy resin, covered with a random mat of chopped asbestos fibres, impregnated with resin, covered with a further layer of carbon fibres, impregnated with resin, the mould closed and curing effected. A composite material rod may be produced by impregnating a tape comprising uni - directional glass fibres warp tows with carbon fibre warp tows along one selvedge and weft tows of lighter glass tows with an uncured resin containing a hardener and catalyst, rolling the tape crosswise beginning with the glass selvedge so that the carbon fibre tows run longitudinally along the outer surface and curing.

Filed: 1922-11-28
Abstract: 210,223. Marks, E. C. R., (Toledo Scale Co.). Nov. 28, 1922. Counting by weighing.-In a weighing and counting scale of the kind having a movable and a non - movable ratio pan supported on the scale beam, the movable ratio pan is carried by a bar which is pivoted to the beam and which is counterbalanced so as to bring the centre of mass thereof and the parts carried thereby substantially into the pivotal axis of the bar. The movable ratio pan 20 is carried by a bar 18 pivoted upon the beam 9 and counterbalanced by a weight 21. As the bar 18 is turned upon its pivot 30 one end rides upon a curved indicating strip 22. The second ratio pan 13 hangs from the end of the beam. In determining the number of articles in a given lot placed upon the platform 2, a few of the articles are placed one by one in the ratio pan 13 until the usual indicating pointer 7 returns as near as possible to zero without going beyond. One article is then placed in the ratio pan 20 and the pan is moved over the indicating strip 22 until the indicating pointer 7 reaches zero. The number indicated on the strip 22 is added to the product of the number in the pan 13 and the leverage ratio of the scale the resulting computation giving the number on the platform. A chart 24 may be used to ascertain the product. When the scale is to be used for weighing purposes only the ratio pan 13 may be removed, and a sliding poise 14 adjusted to compensate for the removal.
