Title: Improvements relating to the manufacture of aliphatic alcohols
IPC: C07C29/04
Filed: 1931-09-11
Abstract: Aliphatic alcohols are obtained by the hydration of olefines in presence of basic substances, especially hydroxides of alkali metals. The temperature may be 100-300 DEG  C., and atmospheric, reduced, or increased pressure may be employed, but preferably, especially with gaseous olefines, pressure is employed which may be up to 50 atmospheres.  If little water is present the product may be an alcoholate, but preferably sufficient water is used to produce alcohols.  Liquid olefines may be heated or boiled with alkali hydroxide, preferably in concentrated aqueous solution; or gaseous olefines may be absorbed in circulating aqueous alkali; or a mixture of olefine and steam may be led in contact with aqueous or solid alkali supported on a carrier such as charcoal, silica gel, asbestos, or pumice.  The alcohol may be separated by fractional condensation, or the alcohol and steam may be condensed together, the condensate being fractionally distilled with or without an entraining agent. Instead of alkali hydroxides there may be used other basic substances such as calcium or magnesium oxide, which may be used in admixture with one another or with alkali hydroxides.  The basic substance may also be used in conjunction with other substances such as thoria or metals such as platinum, gold, silver copper, tungsten, and manganese, or their compounds.  In examples (1) a mixture of equal volumes of ethylene and steam is passed into 50 per cent caustic potash solution at 150 DEG  C. and 20 atmospheres pressure; (2) a mixture of 1 volume of ethylene and 2 volumes of steam is circulated over pumice impregnated with sodium hydroxide at 200 DEG  C. and 30 atmospheres pressure; the vapours are cooled after each treatment or preferably after each ten treatments, the alcohol and steam being condensed together.

Abstract: 691,697. Valves. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., PETER, L. H., and KERSHAW. N. G. May 23, 1951 [Oct. 19, 1950], No. 25490/50. Class 135 A valve, applicable for controlling pneumatically operated colliery decking plant, is jointly controlled by a handle operated rotary valve and by at least one supply and exhaust valve assembly operated to close the exhaust and open the supply valve by displacement of the handle in a direction other than that for adjusting the rotary valve, the handle being returned to its non-operative position when the operator releases his grip on the handle. When an operator holds the handle 11, Fig. 1, to turn the rotary valve 2, Figs. 1 and 2, the handle is pivoted forward against a spring 14 to close an exhaust valve 23 and open an air inlet valve 22 whereby pressure is supplied via port 3 and passage 21 to the pistons 19, 20 which respectively close main valves 15, 16 and open valves 26A, 26B. By rotating the valve 2 to the " scotches off " position air is supplied through an inline valve, port 27, valve 26B, passage 29 and the valve 2 to a passage 9 and port 10 leading to a scotch block operating device. Rotation of the valve 2 to ram forward position allows air to pass through the port 27, valve 26B, passage 29 and the valve 2 to passage 7 and port 8 leading to the back of the ram piston, the front of the piston being vented to atmosphere via port 6, valve 26A, passage 30, the valve 2, passage 24 and port 25. In the ram back position, air enters port 3, passage 4 and the valve 2 and passes via passage 30 and valve 26A to port 6 leading to the front of the ram piston, the back of the piston being exhausted through port 8, passages 7, 24 and port 25. In any position of the valve 2, releasing the handle allows valve 22 to close and opens valve 23 to exhaust all the ports 6, 8 and 10.

[Also in Divisions H1 and H5] An electric heating fabric, which is either woven, non-woven pile, knitted or braided, incorporates electric resistance filaments (P.T.C. elements) made of resistive particles homogeneously dispersed in a .non-conductive plastics carrier material. The resistive particles may be graphite, carbon black, lamp black, copper, iron, zinc, magnesium or alloys of constantan, nickelin, monel metal (R.T.M.) and phosphor bronze. Lists of carrier materials are specified. Insulating material other than the carrier material may be incorporated in the resistive filaments, such a material should possess a greater thermal expansion and specific resistance than the resistive particles. The insulating materials may be liquid, e.g. oils, solid, e.g. acetyl cellulose, glass powder, bentonite, flint &c., or pasty, e.g. waxes or greases. The heating fabric may be used in curtains, upholstery, blankets, blinds, shades, tapestries, socks, gloves, robes, suits, carpets or rugs. In the rug shown the resistive heating filaments 15 are woven as weft threads and are connected to the supply by conductive warp threads 20 at the opposite edges of the rug. In Fig. 5 (not shown) the conductive supply members are parallel to the resistive filaments and the resistive filaments are connected to the supply members by rows of intersecting conductive members which rows engage alternate supply members. In another arrangement, (Fig. 6 not shown) the resistive filaments extend between supply conductors at the edges of the fabric, the supply conductors being connected to further conductive members which intersect and thereby electrically connect the resistive filaments. In Fig. 7 (not shown) the resistive filaments are perpendicular to the supply members and are electrically interconnected by a plurality of loose members extending parallel to the supply conductors. The supply conductors may be stitched to the fabrics or stuck to the fabric or it may be formed as a foil or a conductive paint. The resistive filaments have a positive temperature coefficient of resistance. Reference has been directed by the Comptroller to Specification 1,053,331.

Filed: 1966-06-09
Abstract: 1,149,266. Cross-head extruders. GENERAL CABLE CORP. 9 June, 1966 [29 June, 1965], No. 25678/66. Heading B5A. An extrusion machine for coating conductors with either rubber or plastics comprises a lined barrel 14<SP>1</SP> and a cross-head 20<SP>1</SP>, the passage of material from one to the other being sealed against leakage by co-operation between an axially movable ring 50 and a spacer 66. Ring 50, preferably of annealed steel, is machined to fit liner 16<SP>1</SP> and its passageway diverges upstream to accommodate the conical end of screw 70. Further, the pressure of the extruding material on surface 54 of the passageway forces ring 50 into contact with spacer 66 via a surface 74 of reduced diameter. Similarly, spacer 66 is provided with a surface 68 of reduced diameter and the gap between surface 54 and the conical end of screw 70 may be varied by changing the spacer. A combined breaker plate and screen pack 60, 62 may be integral with either ring 50 or spacer 66 or be inserted as a separate component. In a modification, Fig. 4 (not shown), sealing ring (80) has two diverging portions as at surfaces (88) and (90), the former subtending the smaller angle, and in this case the pressure of the extruding material on surface (88) causes ring (80) to expand into contact with the barrel liner. Screw (82) has an end portion (84) with one surface parallel to surface 88 and a second surface which diverges somewhat with respect to surface (90).

Title: Improvements in or relating to processes for preparing pure crystalline salts of penicillin, and the pure crystalline salts of penicillin resulting therefrom
IPC: C07D499/14
Filed: 1946-09-02
Abstract: Pure crystalline penicillin salts are obtained by adding to an aqueous solution of a penicillin salt an organic solvent for the salt which when heated with water forms a vaporous mixture containing a substantial proportion of water, distilling the mixture to remove substantially all the water, further concentrating the solution if necessary, and allowing it to stand, preferably at a low temperature for crystallization to occur. Alternatively, the solvent may be evaporated substantially completely under reduced pressure at a low temperature.  The starting materials and the salts obtained are the same as those of Specification 642,369, the organic solvents of that Specification may be used, and in addition certain glycols are specified as suitable.  Examples show the crystallization of the potassium, sodium, ammonium and rubidium salts, using as solvents n- and sec.-butyl alcohols and 2-methyl-2 : 4-pentanediol.

Abstract: 1305699 Colour television tubes RCA CORPORATION 19 April 1971 [6 April 1970] 26326/71 Heading H1D [Also in Division B3] In a colour television tube having a shadow mask supported by springs from studs on the envelope, the aperture in the spring through which the stud passes is defined by curved surfaces having smaller curvature than the co-operating surface of the stud. In Fig. 9 the aperture is defined by three circular arcs 27 centred respectively at points a, b and c. The radius of the arcs should be 4-10% greater than the radius of the inscribed circle 17<SP>1</SP> which is the desired contact position of a conical stud; the actual contact position may be as shown at 17 and the contact area is still great enough to prevent the gouging which may occur in known arrangements. The edges of the aperture may be curved in planes containing the axis A. In a specific example, Figs. 11 and 12 (not shown), the radius of the circle 17<SP>1</SP> is 0À110 inch, the radius of the arcs 27 is 0À115 inch and their centres are 0À005 inch from the axis A, and the edges are curved to a radius of 0À125 inch; the position of the centre of curvature of the edges depends on the taper of the studs which may be between 7 and 12 degrees. As an alternative the tip of the stud may have the curved surface illustrated and co-operate with a circular aperture.
