Title: Improvements in or relating to temperature control in refrigerated storage cabinets or receptacles
IPC: F25D23/00
Filed: 1932-10-01
Abstract: 408,575. Refrigerators. ELECTROLUX, Ltd., 153, Regent Street, London.- (Backstrom, S. M. ; 2, Norrmalmstorg, Stockholm.) Oct. 1, 1932, No. 27312. [Class 29.] In ice-cream conserving and other cabinets, the temperature in one or more of several receptacles cooled by the same cold source may be modified to adapt the receptacle for storage of goods either at low or at medium temperature, by interposing a resistance to the flow of heat from the receptacle to the cold source and reducing the resistance to heat flow to the receptacle from the surroundings. The means employed preferably consists of a removable liner or sleeve 17 to the storage receptacle 10, the lower part of the sleeve near the cold source being insulated, preferably by a double wall 19, 18 with air or gas insulation between the walls, and the inner wall of the sleeve being continued upwards as at 24 towards the metal lining 15 of the mouth of the receptacle to promote leakage of heat into the receptacle. The two walls of the sleeve may be of aluminium spaced by wood blocks 20, 21, and the inner wall is preferably thicker than the outer. By the use of the sleeve a cabinet designed solely for low temperature storage of ice bricks may be readily fitted with a receptacle for storing ice cream.

Title: Process of improving the strength qualities of textile fabrics treated with impregnating agents
IPC: D06M15/423
Filed: 1936-10-08
Abstract: To improve the tensile strength and resistance to fracture of impregnated textile fabrics, e.g. of cotton, artificial silk, linen, or mixed fabrics, the strength qualities of which have been diminished by treatment with synthetic resins or aldehydes, the latter with or without acid amides, the fabrics are subjected to a weak acid or acid salt treatment only carried to such an extent that the non-creasing or similar effect produced by the impregnating treatment is substantially retained, whereupon the fabric is washed, and, if desired, neutralized.  Suitable acids are inorganic acids, e.g. hydrochloric or sulphuric acid or organic acids such as oxalic or formic acid, and suitable acid salts are, e.g. alum or aluminium chloride.  The acid treatment partially removes the resin or aldehyde from the piles of the fabric.  Fabrics which can no longer be used for embossed or calendaring effects owing to excessive impregnation with synthetic resin may be rendered suitable again for that purpose. In an example a fabric which has been made unwashable by treatment with synthetic resin components or carbamide and aldehydes and which has diminished tensile strength is treated with sulphuric acid of 6 DEG  B<\>ae. for \ba1/4\be hour at 40 DEG  C.  It is then rinsed and washed, and, if desired, neutralized by treatment with ammonia.  The tensile strength is then hardly inferior to that of the starting material.

Title: Improvements in and relating to the separation of materials
IPC: B03B4/00
Filed: 1932-10-04
Abstract: In the separation of materials of different sizes and specific gravities, such as in the cleaning of coal, by stratifying the mixed materials, previously graded by screening into batches of limited size range, under the action of an upwardly directed air current, a preliminary winnowing operation is performed on the materials for the purpose of carrying off the smallest particles of the lighter products and facilitating the subsequent screening and separating operations.  In the example described, raw coal ranging in sizes from 1/2 " to 0" is first treated in apparatus such as described in Specification 338,119, [Class 117], for removing the lighter particles up to 1/32 ".  The remainder is then divided into batches ranging from 1/2 "-\ba1/8 " and 1/8 "-\ba1/32 " respectively by screening, and treated on pneumatic separators appropriate thereto. The product that passes through the second screen consists mainly of the small size denser constituent, e.g. shale, of the original material and is thus removed from the action of the pneumatic separators.

Title: Improvements in and relating to the manufacture of grinding bodies
IPC: B24D18/00
Filed: 1933-10-10
Abstract: A method of manufacturing grinding bodies interspersed with hollow spaces is characterized in that, from abrasive material and binding medium small structures containing a plurality of grains of abrasive material, e.g. in the form of granules, lumps or strings, are produced, and these structures are cemented together in such a manner that hollow spaces, which are large compared with the abrasive grains, remain between the structures.  The total volume of the hollow spaces amounts to at least 50 per cent and preferably more than 60 per cent of the total volume of the grinding body.  The abrasive grains may be, for instance, of corundum, silicon carbide, emery or glass.  As binding media may be used clays or kaolin mixtures, shellac, or artificial resins, e.g. that known under the Registered Trade Mark "Bakelite."  The structures can be made by pressing a paste consisting of the grains and binding medium through perforated plates.  The structures are filled into a mould, with or without additional binding medium which may be of a different kind from that used in making the structures, and are then hardened and coalesced, as by firing; or they may be hardened by heat and/or coated with solid or liquid binding medium prior to introduction into the mould. Structures in the mould may be heated slightly to ensure cohesion, solutions or suspensions of binding medium being then run in and excess being removed by draining or centrifuging.  The porosity of the grinding body may be increased by blowing or generating gas therein, e.g. by adding hydrogen peroxide or employing the binding medium as a foam.
