Title: Improvements in or relating to the impregnation of fibrous material
IPC: D21H17/60
Filed: 1939-05-06
Abstract: 530,374. Impregnating-compositions for electric insulation; electric cables. CALLENDER'S CABLE & CONSTRUCTION CO.. Ltd., HILL, H., and BECKINSALE, S. May 6, 1939, No. 13617. [Class 140] [Also in Group XXXVI] Fibrous material, e.g. paper or cloth, is impregnated by treatment with (a) an oleaginous liquid vehicle and diluent, (b) a body consisting of or containing free organic acid and (c) a base which reacts with the acid within the material to form a water-insoluble soap. The oleaginous liquid is miscible with or a solvent for the acidic bodies and free from water, for example, petroleum oils, or mixtures thereof with petroleum products, coal tar products, natural bitumens or synthetic resins. Rosin oil may function both as acidic body and oleaginous liquid vehicle. The basic substance may be calcium hydroxide or calcium, magnesium, zinc or aluminium oxides. The acidic body may be a higher fatty acid, e.g. stearic, palmitic or oleic acids, a natural resin such as rosin, or a destructive distillation product of organic material, e.g. pine tar, stockholm tar, rosin pitch and rosin oil. Coal tars, coal tar pitches and petroleum residual pitches may be added. Either the acidic or the basic component may be incorporated in the fibrous material prior to treatment with the remaining components. For a cable dielectric, paper may be loaded with hydrated lime during manufacture or applied in powder form whilst applying the paper to the conductor. After drying, e.g., at 140‹C. the hot cable core is immersed in a cold mixture of rosin oil and thin transformer oil thinned if desired with naphtha or a chlorinated solvent. For cable sheaths an aqueous suspension of slaked lime is applied and the paper or fabric and quicklime is dusted on the wetted material which is then impregnated with a mixture of blown asphalt, rosin, oleic acid and transformer oil. Alternatively a mixture of rosin oil, lime, calcium hydroxide and transformer oil is used for impregnating immediately after mixing. Embossed paper, e.g. of the kind described in Specification 352,533 may be used as the fibrous material.

Abstract: 723,150. Internal shoe-drum brakes, particularly for cycles and motor-cycles. GIRLING, Ltd. May 18, 1953 [May 29, 1952]. No. 13640/52. Class 103 (1). In internal shoe-drum brakes for cycles and motor-cycles, the arcuate shoes are separated to engage the drum by a wedge member formed by or on the inner end of a lever which is angularly movable about a fixed axis parallel to the line of movement of the actuated shoe ends and the outer end of which is adapted to be coupled to an actuating rod or cable. The invention is shown illustrated and applied to a motor-cycle in which the arcuate shoes 10, 11 are mounted to rock and slide at one end on an adjuster 12 secured to the stationary back-plate 13 of the brake. The other ends of the shoes are engaged by the outer ends of opposed tappets 14 slidably mounted in an expander housing 15 mounted on the back-plate. The ends of the adjuster and the expander housing are slotted to prevent lateral movement of the shoes. The inner ends of the tappets 14 are formed with transverse oppositely inclined notches 17 in which are located free rollers 18. When the wedge 19, formed by the sloped inner end of lever 20, is moved transversely in a direction substantially parallel to the back-plate the tappets are forced apart to separate the shoes and apply the brake. The lever 20 is mounted to rock about a pivot pin 21 in the housing 15 and the outer end projects through a space in the back-plate 13 to provide an eye 23 for the rod or cable connection. A flexible boot 24 extends over the lever 20 and the housing box 22 to protect the mechanism against the entry of water or dust.

[Class 120(ii)] [Also in Groups XXIV and XXX] Rigid fixing of a rod constituting the stationary one of twc relatively movable machine parts characterizes a ratchet device which comprises a tongue shaped part connected with the rod of said machine part, and with the other or movable machine part by two members exerting forces to maintain the tongue in a jamming position, one force acting in the free and the other in the locked direction of relative movement. As shown, applied to a cross winding machine, an arcuate rod 4, rigidly fixed to the machine frame 16, has sliding thereon with clearance one end of a loose tongue 9, the other end of which engages a slot in a member 7, pivoting about a shaft 15 and loaded by a counterbalance weight 22. An axle 23, loaded by a torsion spring 26, has a finger 25 attached to a part 24 thereof to force the tongue outwardly intermediate its two points of contact, and the whole arrangement is such that in the rest position an edge 19 of the slot in the member 7 tilts the tongue 9 until the sides of the bore therein jam on the rod 4. The finger 25 conveys outward movement of the tongue 9 on the rod 4 when the member 7 pivots outwardly on building up of the coil, but due to the tilting on the rod the tongue cannot move inwardly unless an arm 27 is depressed causing a finger 14' to engage the top thereof and free the jamming action. The edges of the tongue opening may be rounded off. The invention may be applied to tensile testing machines. U.S.A. Specification 2,165,018 is referred to.

Title: Improvements in the dyeing of leather, skins and/or animal fibres attached thereto
IPC: D06P3/30
Filed: 1956-05-09
Abstract: Leather, skins and/or animal fibres attached thereto are dyed by contact with an organic compound which is at most sparingly soluble in water at the temperature of dyeing and with an aqueous solution or dispersion of a coloured substance, the solubility of the coloured substance in the organic compound at the temperature of dyeing being greater than its solubility in water. Coloured substance is defined, as a dyestuff, lake or a coloured organic compound insoluble in water.  Specified organic compounds are n-butyl alcohol, amyl alcohol, n-hexyl alcohol, cyclohexanol, "Alphanol" (Registered Trade Mark), "Naranol," geronial, citronellol, benzyl alcohol, thymol, carvacrol, amyl lactate, dibutyl phthalate, n-butyl acetate, benzaldehyde, acridine, acetophenone and toluene.  Dyestuffs which may be used in the treatment of skins and furs as above include, disperse dyes, acid wool dyes, direct dyes, premetallized dyes, organic and inorganic pigments, anionic dyes and water insoluble organo-metal complexes. If the organic compound is a liquid at ordinary temperature it may be applied directly to skin or fur. Alternatively the organic compound may be applied in the form of a solution in an organic solvent or as an emulsion in a suitable carrier, e.g. water. Dyeing may be effected in the presence of a mixture of organic compounds.  When the organic compound is applied simultaneously with the dye, the skin or fur may be treated with a solution or dispersion of the dye containing the organic compound in the form of an aqueous solution or emulsion.  Again, the solution or dispersion of the dye may contain the organic compound together with an organic solvent which is miscible with both the organic compound and with water.  The dye may be applied to the skin or fur by spraying or brushing and subsequently the skin or fur may be immersed in a bath containing the organic compound.  After the skin or fur has been subjected to dyeing treatment as described above it may be washed with an aqueous solution of dispersing agent.  Examples are given.  Specification 542,171 is referred to.
