Title: Improvements in or relating to supporting pads for vacuum flasks
IPC: C03B23/13
Filed: 1953-08-11
Abstract: A resilient supporting pad positioned between the inner and outer glass walls of a vacuum flask is made by (i) washing in distilled water short heat-resistant fibres having a low heat conductivity and chemically inert to the silvering of the glass (ii) partially drying the washed fibres to remove therefrom approximately 90 per cent of the distilled water absorbed thereby (iii) filling and pressing the partially dried fibres into a mould having the shape of a pad and (iv) completing the drying of the fibres in the mould.  Suitable fibres are asbestos, purified by normal methods, 1/16 in. to 1/8 in. long.  The partial drying is done in an open topped tank with a perforated plate spaced above the bottom and covered with a cloth on which the wet fibres are spread.  A vacuum pump connected to the space below the plate is operated and moisture is drawn from the wet fibres through the cloth.  The moulds are formed by holes of the required diameter extending through a metal plate of the required thickness, lying on a flat surface.  The material of the plate should not impart to the pads any particles which might have an undesirable chemical reaction with the heated glass or silvering, suitable materials being aluminium alloy and stainless steel. With about 90 per cent of the water removed, the fibres have the consistency of putty and are filled and pressed into the holes by means of a trowel resembling a brick-layer's.  When the moulds are filled the plate is put in an oven to complete the drying of the fibres, or it may be left to the atmosphere.  The completed pads can be removed from the mould plate, which is held over a receptacle, by gentle tapping.  The washing and partial drying may be omitted if the fibres are sufficiently pure, the fibres merely being wetted to the required consistency.  Distilled water is not essential if the water used is free from soluble or other substance which would cause the fibres treated therewith to react with the silvering.

Title: Improvements in or relating to the manufacture of water soluble organic sulpho compounds
IPC: C07C303/00
Filed: 1934-07-20
Abstract: A mixture of one or more monohydric unsaturated fatty alcohols with castor oil or ricinoleic alcohol is sulphonated at a temperature of -5 to +30 DEG  C.  In examples: (1) a mixture of oleic alcohol and ricinoleic alcohol is sulphonated with 98 per cent sulphuric acid; (2) a mixture of oleic alcohol and castor oil is treated first with sulphuric acid and then with chlorsulphonic acid.  The alcohols obtained by reduction of unsaturated fatty acid esters, e.g. fish oils are mentioned.  The products may be used as wetting, washing, dispersing and emulsifying agents.  The Specification as open to inspection under Sect. 91 refers also to the use of ricinoleic acid as starting material.  This subject-matter does not appear in the Specification as accepted.ALSO:Products stated to have emulsifying and dispersing properties are obtained by sulphonating, at a temperature between ,5 and +30 DEG  C., a mixture of one or more monohydric unsaturated fatty alcohols with castor oil or ricinoleic alcohol.  As monohydric unsaturated alcohols are mentioned oleic alcohol and those obtained by reduction of unsaturated fatty acid esters, e.g. fish oils.

Abstract: 336,969. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). July 22, 1929. Wood, treating with liquids.-Wood is acylated by means of the anhydride of an organic acid in the absence of inorganic catalysts. The wood, such as beech, aspen, fir, pine, and the like must be dry and preferably disintegrated, but sheets or large pieces may be used whereby superficial acylation is obtained. If desired, the initial material may be deresinified and freed from wax by means of solvents such as alcohol-benzene mixture, or given a short treatment with steam or hot water in order to loosen the texture. In an example, dried fir wood is added to acetic anhydride which is boiled under a reflux condenser. Other suitable anhydrides which mav be used are butyric and benzoic anhydrides. It is stated that the acylation increases the tensile strength and the fastness to light of the wood.

Abstract: 520,879. Brakes. BUDD WHEEL CO. Aug. 2, 1938, No. 22819. Convention date, Aug. 19 1937. [Class 103 (i)] In a brake arrangement for a rail car truck or the like supported by springs on a pair of axles 14, the brake mechanism on each axle has a torque member 34a extending inwardly from the axle towards a central transverse member or bolster 16 and secured to the truck frame at 40 so as to transmit thereto a turning moment about a transverse axis, this turning moment being counter to and substantially equal to the moment due to the inertia of the body when the brakes are applied, whereby no substantial change in spring loading is effected during braking. The turning moment due to the brake torque depends on the angle Ï which the resultant brake reaction force P makes with the horizontal, and the manner in which this angle or the necessary distance of the torque arm pivot 40 from the axle 14 can be calculated is described in the Specification. The torque arms 34a are oppositely inclined as shown, and the car body rests on the centre plate 17 of a swing-type bolster 16.

Abstract: 387,401. Loft-ladders. GRANT, C. M., 112, Carlton Gardens, Crookston, Glasgow- Aug. 18, 1931, No. 23210. [Class 20 (ii).] A collapsable loft-ladder or folding stairway carries means at its upper end which slidably engage with stationary, parallel, inclined guides, the engagement being such that the collapsed ladder is free to swing into a substantially vertical position away from the loft door when raised clear of the loft floor. In the form shown, the ladder comprises three sections 1, 2, 3, which are hinged together about hinges 4, 5. Brackets 11 are carried by the side rails of the uppermost section 3 and slidably engage with guides 12 extending between the loft floor 10 and a member 13 on the roof rafters 14. The ladder is counterbalanced by weights 15 which are connected by cables 16 to the brackets 11. The ladder is raised and lowered by cord 18, one end of which is attached to the section 2 while the other end is connected to the lowermost rung or to a cross-piece of the section 3. A detachable cord 21 is used to effect the connection between the cord 18 and the section 2. Upon operating the cord 18, the sections first rotate until they lie face to face. The collapsed ladder then moves bodily upwards upon the guides 12 until the lower end thereof is clear of the loft floor. The apertures in the brackets 11 are sufficiently loose upon the guides to enable the ladder then to swing into a substantially vertical position, Fig. 4, on the loft floor. A roller 26 facilitates the raising and lowering operations. A detachable pin is adapted to pass through holes in plates on the abutting ends of the sections 2, 3 to keep these sections in alignment when the ladder is extended.
