Title: An improved process for the production of base-exchanging substances
IPC: C01B33/46
Filed: 1927-07-06
Abstract: 279,028. Rosenheim, A. Oct. 16, 1926, [Convention date]. Purifying liquids.- Solid natural or artificial silicates having no appreciable base-exchanging powers are rendered base-exchanging, by treatment under pressure with the requisite amounts of solutions of acid, neutral, or alkaline reagents, or successively with two or more of such reagents of the same or of different character in which case only one, and preferably the last, treatment may be effected under pressure; or several treatments with a single reagent may take place, or two or more reagents of the same kind may be employed together. In examples pressures up to 10-15 atmospheres are specified, and temperatures varying from normal up to 170-200‹ C. may be used. After impregnation with solutions of the reagents, the substances may be further treated with precipitants for the solutions used under diminished, normal, or increased pressure, this treatment being followed, if desired, with further treatment with reagents, examples describe the treatment of trachytic tuffs, palagonite tuffs, phonolite tuffs. or glasses rich in alkali with sulphuric acid or a bisulphate solution; of baked or unbaked kaolin with an alkali or alkaline earth hydroxide; of shale with a waterglass solution; of baked bricks, clinkers, baked clay, or minerals such as feldspar, leucite, phonolite, basalts, slags, lava, unbaked clay, field soil, or mixtures thereof with hydrochloric acid followed by alkali silicate, or caustic soda, or by alkali carbonate, phosphate, or aluminate. one treatment at least being under pressure and the other, if desired, being under diminished pressure; and of granite with hydrochloric acid followed by a waterglass solution. When alkaline earths or their salts are used as reagents, it is advisable to replace them in the product with alkali, as by a further treatment with alkali or alkali salts. Oxides such as ferric oxide, alumina, silica, zirconia, or titanic oxide may be precipitated in or on the substances treated by first treating the latter with a salt solution from which the oxide may be obtained, and then with an acid or alkaline reagent. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter :-The treatment of glauconite with a solution of sodium or potassium chloride or nitrate, sodium phosphate or ammonium chloride; dispensing with pressure when a plurality of treatments is effected, as for instance, in the treatment of pumicestone first with an acid and then with an alkali silicate; and the impregnation of coke first with aluminium sulphate and then with alkali silicate, followed if desired by a treatment with common salt. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 265,578 and 266,313.

Title: Improvements in or relating to tools for mounting elastic sleeves on rods, cables, insulated conductors and the like
Inventor: THOMAS BENJAMIN ALFRED
IPC: H02G1/14
Filed: 1951-08-01
Abstract: 711,499. Fitting elastic sleeves on cables. ELECTRIC & MUSICAL INDUSTRIES, Ltd.,. July 15, 1952 [Aug. 1, 1951], No. 18182/51 Class 108(3) A tool for mounting elastic sleeves on wires &c. prises a tube 26 slidably mounted in a casing 10 and urged by a spring 30 so that it normally projects from an aperture 12<1> in the casing 10 (as shown) whereby an elastic sleeve (not shown) can be applied thereto, and actuating means for retracting the tube 26 so that the sleeve is removed from the tube by engagement with an area surrounding the aperture 12' the sleeve thus becoming applied to a wire &c. (not shown) previously inserted in the tube. Tn the construction shown in Fig. 6 the tube 26 is rigid with a tube 24 slidable within the housing 10 against the action of a spring 30. A rod 32 is carried by a tube 33 slidable within the tube 24. A trigger 51 is pivotally-mounted on a pin 53 rigid with the tube 33. The trigger extends through a slot 39 in the tube 24 and a slot 38 in the housing 10. In operation, an elastic sleeve is pushed on to the rod 32 and from thence on to the tube 26 (the rod and tube are tapered and polished). This is effected by means of an apertured rubber pad 43 carried by a holder 72 on an axially movable rod 61. A co-operating pin 70 and helical groove 68 cause (on axial movement of the rod 61) pad 43 to be swung from a position out of alignment with the rod 26 to a position (shown) in which the pad 43 is coaxial with the rod. On further axial movement the pad 43 engages the sleeve and forces it into position on the tube 26. The trigger is given a slight rotation to disengage a retaining catch 58 and is then drawn rearwardly. This effects retraction of the rod 32 further into the tube 26 within the housing, and makes way for the cable which is then inserted. When the trigger reaches the end 39" of the slot 39 (which is shorter than the slot 38), it picks up the tube 24, and further trigger movement retracts the tube 26 into the nose 12 of the housing and so leaves the sleeve on the cable. Provision may be made for the rod 32 to be entirely removed so that the cable may be passed right through the housing. 10. The nose 12, tube 26 and rod 32, may be made interchangeable with corresponding parts of different dimensions. In a modification, Figs. 1 to 5 (not shown), the trigger 51 is replaced by finger-holds disposed on opposite sides of the housing. The tool may, however, have pedal or power-actuating means. The elastic sleeves may be of polythene. According to the Provisional Specification, the elastic sleeves may be removed from the tube 26 manually and only one uf the members 26 and 32 need be tapered. The elastic sleeves may have diameters of .125 in. or less.
