Abstract: 1447049 Coated marking element P P PAYNE Ltd 29 Nov 1973 [18 Dec 1972] 58403/ 72 Heading B2E [Also in Division B6] A marking element suitable for marking a textile article comprises a support and marking characters and has at least one face which includes a heat curable polyurethane composition comprising (a) a liquid urethane prepolymer of which the free isocyanate groups are substantially blocked and (b) an elastomeric polyamine-extended polyurethane. The element may be in the form of a label or a transfer (see Divn. B6), the support being respectively permanent or temporary. When permanent, the support may be of woven fabric, particularly of nylon 66 yarns, or of bonded fibres and may be impregnated or coated with the polyurethane composition. One face of the support may carry the marking characters, which may be printed on with an ink comprising the heat curable polyurethane composition, and the other face may include the composition. The marking characters may be overcoated with a transparent layer which may be continuous or merely in registry with the characters and which may also comprise the polyurethane composition. The label may be applied to a cotton fabric by heat and pressure.

Abstract: 1335218 Fluid springs BARRY WRIGHT CORP 10 Dec 1970 [19 March 1970] 58716/70 Heading F2S A "piston" 25 supported in a chamber 13 by fluid under pressure is maintained at a constant height by inlet and exhaust valves 14, 32-34, the valve elements 43, 34 of which are rigidly interconnected. One of the valves must be in the "piston". As shown both valves are closed. If the piston rises, the valve seat 33 is withdrawn from the valve element 34 to open the valve and allow air to pass out until the piston returns to the mean position and closes the valve. If the piston falls below the mean position, the valve element 43 moves off the valve seat 42 and air under pressure is admitted until the piston rises, shutting off the valve. In Fig. 2 (not shown) the valve seats are universally mounted, the inlet valve is in the piston, and there is a fluid-containing diaphragm bounded bias chamber (64) above the piston. Fluid under pressure is applied to the inlet valve either directly or via the bias chamber. Three of the units mount a vibrating machine (not shown).

Patent GB-636595-A (GB)
Abstract: 636,595. Indicating-apparatus; totalizators. UNION TOTALISATOR CO., Ltd., and HANDLEY, J. Oct. 16, 1946, No. 27746. [Classes 106 (i) and 106 (iv)] [Also in Groups XXXVI and XXXVIII] A device for computing the ratio of the total number of bets placed to the total placed on each runner comprises a rotatable frame, the position of which at any time indicates the ratio and is determined by the relative positions of weights 6, 7 which are moved along lead-screws 4, 5 mounted at right angles to each other on the frame and by electromagnets 9 and 10 in accordance with impulse received from the competitor and grand total indicator respectively. Each of the stepping magnets 9, 10 actuates a lead screw through one sun member of a differential gear 13 or 14. The weights are reset by further electromagnets 15 and 16 which rotate the shafts in the opposite direction through the other sun members. Since the odds scale obeys a tangent law excessive crowding at one end is avoided by making the leadscrew operated by the competitor counter of greater pitch than that operated by the grand total counter. Current is conveyed to the electromagnets by light springs 22 to 25 the torsional effect of which is balanced by a small weight, the suspension of which passes over a snail cam. Further similar springs form part of the circuit of a remote indicator of the type described in Specification 636,596, [Group XXXVIII]. The angular position of the frame is signalled to this remote indicator by a series of commutator segments mounted on a ring which rotates with the frame, segments 1, 4, 7; 2, 5, 8; 3, 6, 9; &c. being commoned together and successively earthed to energize stepping magnets at the indicating position.

Title: Zeolitized honeycomb structure
IPC: C01B39/20
Filed: 1979-03-23
Abstract: A self-supporting monolithic body comprises an amorphous alumina-silica skeleton of inter-connecting cells, e.g. a honeycomb, with crystalline synthetic zeolite integral with and exposed at the cell walls. In its preparation, for example, hydrated kaolin is mixed with a binder to form a solid self-supporting honeycomb by extrusion. The binder is removed and the residue is calcined to dehydrate the clay. The rigidized honeycomb is immersed in a solution of sodium hydroxide or other base(s) and heated to form a crystalline zeolite in situ. The base extracts a portion of the silica and/or aluminia in the calcined structure, whereby the nonzeolitic portion of the structure is porous and the zeolite crystals are accessible when the structure is used as a catalyst, catalyst support or adsorbent. Such structures are peculiarly suited to high space velocity processes such as reduction of nitrogen oxides.
