Title: Improvements in or relating to the extraction of animal glue
IPC: C09H3/00
Filed: 1953-12-31
Abstract: Collagen-bearing animal tissues, e.g. cattle hide trimmings or bacon skins, are acidulated with a water-soluble acid, e.g. to a pH between 1.5 and 6.0, and glue is extracted by treating them with water kept at a non-acidic pH by contact with a water-insoluble basic compound which reacts with the acid to form an insoluble salt, the tissues being maintained internally at an acidic pH, e.g. below 6.5, during the extraction, which may be effected in four stages at temperatures of 65, 75, 85 and 100 DEG C. respectively.  The water-soluble acid may be sulphuric, sulphurous, phosphoric, citric or oxalic acid.  The water-insoluble basic compound may be dispersed in the water and may be an alkaline earth carbonate, e.g. calcium carbonate, or an oxide, e.g. aluminium oxide.  The tissues may first be soaked in dilute hydrochloric, nitric or acetic acid, which must be replaced by an acid forming an insoluble salt with the water-insoluble basic compound, before glue is extracted.  To facilitate extraction of glue, the tissues may be conditioned in a saturated lime solution, in hydrochloric acid at pH4 in the presence of sodium silicofluoride and native yeast cultures, or in an aqueous solution of sodium silico-fluoride in the presence of native yeasts and added cultures of Mycoderma and Torulopsis yeasts.

[Also in Division B7] An industrial truck comprises a body 11, mast 12 and loadcarrying platform 13, the truck having front wheels 14 running on a concrete floor 21 and rear wheels 24 mounted on an arm 15 which may be fixed or pivoted to the vehicle body and which depends into a slot 16 in the floor, the wheels 24 running in rails 17 thereby guiding the truck. The truck may be additionally guided by a roller 26 running between the rails 17 and mounted from a member 25 depending from the front end of the truck. The truck may be electrically propelled and driven through current collectors 27 which contact conductor rails 28 and 29 mounted in the conduit below the rails 17.

Abstract: 1,160,952. Synthetic polymer-elastomeric articles. DUNLOP CO. Ltd. 26 Aug., 1966 [8 Sept., 1965], No. 38446/65. Heading B5B. [Also in Divisions B7 and D1] An elastomeric article such as a pneumatic type carcass is made by shaping a sheet of orientatable fissile material with elastomeric material applied thereto into annular form and supporting it at each side by means of an endless bead wire, the bead wires being disposed in coaxial spaced apart relationship with the sheet spanning them, the sheet gripping the wires or being bonded or welded thereto, and inflating and expanding the sheet so as to orientate the fissile material and at least partially fibrillating the sheet. By "orientatable fissile material" is meant synthetic linear polymers, e.g. polyamides such as nylon and polypropylene, while natural or synthetic rubber or plasticized polyvinyl chloride are examples of elastomeric material. The elastomeric material may be applied in sheet form. The sheet may be expanded by means of an intermediary internally located expansible resilient rubber diaphragm or tube or may be inflated directly. The diaphragm may have different degrees of expansion over parts of its surface so enabling different degrees of orientation in the sheet to be attained. The fissile sheet may be pre-stretched before stretching to an extent less than that required for fibrillation to occur and a plurality of sheets may be used. Heat may be employed in the inflating or pre-stretching operations. Fibrillation of the fissile sheet may take place towards the end of the expansion and may be induced by relatively rotating or rotatably oscillating the bead wires or by reciprocating them towards and away from one another or by a combination of any of these methods or other means of fibrillation, e.g. twisting, rubbing or impacting the sheet, may be used. Alternatively fibrillation may take place in a finally built up article, such as a tyre, when the tyre is expanded into a mould.

Abstract: 817,229. Dashpots. SMALLPEICE, C. D. P. Dec. 18, 1956, No. 38515/56. Class 108(3) A retarding device comprises a piston 11 carried by a hollow piston rod 14 which is slidable on a fixed tube 17 so that on movement of the piston 11 in its cylinder 10, fluid can flow from the cylinder space beneath the piston, through an orifice 32 to the interior of the piston rod, through the tube 17 and thence via a variable orifice 20 to the cylinder space above the piston 11. As shown, the piston 11 is slidably mounted on the piston rod 14 between an annular stop 33 and an end stop 12. The latter serves to close the upper end of an orifice 31 connecting opposite faces of the piston 11 on downward piston movement. On upward piston movement, the piston 11 moves. downwardly into engagement with the stop 33, and due to flow taking place through the orifice 31, piston movement is not retarded. Compensation for changes in cylinder volume due to differential piston area, is provided by means of a reservoir 26 having a spring-loaded end wall 28. A rubber seal 16 is provided between the piston rod 14 and the tube 17.
