IPC: C22C21/00
Filed: 1919-11-18
Abstract: 159,008. Hurst, J. E., and Ball, E. B. Nov. 18, 1919. Alloys. - A light alloy, suitable for castings which are subjected to high temperatures in use, comprises aluminium and from 0.5 to 6 per cent of chromium, and up to 6 per cent of one or more other metals such as zinc, magnesium, copper, nickel, or antimony, the total amount of these metals being preferably not more than that of the chromium.

Title: A process for improving textile materials
IPC: D06M15/423
Filed: 1934-10-05
Abstract: Textile materials, particularly cotton or artificial silk, in the hank or piece, are rendered crease resistive by treating with the starting materials of synthetic resins, or the soluble intermediate products thereof, and thereafter with a salt solution heated to above 100 DEG  C.  One of the synthetic resin starting materials may be incorporated in the salt bath.  The salts preferably employed are salts of alkaline earth metals, earth metals, or heavy earth metals, e.g. sodium sulphate, magnesium sulphate and magnesium chloride together; the magnesium chloride may be replaced wholly or partly by aluminium chloride, aluminium sulphate, or stannous chloride. Examples of alkaline baths are borax or sodium triphosphate.  The solution may also contain an organic reducing agent, e.g. hydroxylamine.  In an example, an artificial silk fabric is passed twice at 40 DEG  C. through a bath containing 10 per cent urea and ,2 per cent aluminium sulphocyanide, slightly acidified with acetic acid and sodium acetate; then through a 40 per cent solution of formaldehyde of pH 3,5 and dried at 40 DEG  C.; condensation is effected by treatment for 6 mins. in a saturated calcium chloride solution at 125 DEG  C.  In a further example, a fabric is passed three times through a solution of urea, glue and ammonium sulphide, and then through a solution of formaldehyde, hydrochloric acid and hydroxylamine hydrochloride, the fabric is dried and condensation effected by treatment for 4 mins. at 110 DEG  C. in a bath containing 50 per cent MgCl2, 30 per cent MgSO4 and 20 per cent Na2SO4.

Abstract: 691,177. Vacuum-jacketed vessels. SMITH, L. LESLIE-. Nov. 8,1950 [Nov. 8, 1949], No. 28627/49, Class 64 (ii) [Also in Groups V and XVII] In a jug in which a glass vacuum-jacketed vessel 5 is enclosed in a casing made of synthetic resin, such as urea- or phenol-formaldehyde or polystyrene, the casing consists of an upper part 12 and a detachable lower part 15. Moreover, the successive, overall, cross-section dimensions of the upper part 12, from the tip 10 of the pouring lip 9 to the lower extremity of the part, progressively increase so that the part can be moulded and withdrawn axially from an integrally surrounding ring-type mould (see Group V). The pouring lip 9 lies wholly within the perimeter (in plan) of the upper part 12 of the casing. The handle 16 is made of metal or moulded from synthetic resin and the extremities 20 fit into recesses 18 either or both of the recesses being of dovetail section (see Fig. 4) and increasing in cross section towards the bottom of the jug but not so as to oppose withdrawal of the part 12 from its mould. The handle may be a closed loop with projections to fit the recesses. The lower part 15 of the casing may be formed of synthetic resin in a ring mould including a portion for moulding a screw thread 14 for engaging a corresponding thread moulded on the upper part 12, or the lower part may be of metal, pressed from sheet or die-cast and provided with an impressed screw thread for mating with that on part 12. A gasket 23 locates the mouth 4 of the vacuum vessel 5. The Provisonal Specification describes also moulding of the handle integrally with the casing.

Abstract: 533,613. Thermionic valve circuits for multiplex transmission systems. STANDARD. TELEPHONES & CABLES, Ltd. Oct. 27, 1939, No. 28831. Convention date, Nov. 17, 1938. [Classes 39 (i) and 40 (v)] [Also in Group XXXIX] Relates to electric discharge vacuum tubes circuits for use in multi-channel electric wave transmission systems in which the channels are assigned respective carrier frequencies transmitted simultaneously on the same line. According to the invention, a delay network or artificial line is used between the transmission line and the vacuum tubes, the shunt capacities of the network being constituted wholly or in part by the relevant interelectrode capacities of the respective vacuum tubes. At the transmitter, Fig. 2, the several signals are fed to the grids of the several vacuum tubes V1 ... V8, two anodes of which are connected to the common retardation line LAa from which the combined signals issue at S. At the receiver, Fig. 3, the combined signals are fed through a retardation line LAg to the grids of vacuum tubes V1 ... V8, the anode circuits of which include filters F1 ... F8 to separate the signals according to their carrier frequencies. The Specification also describes but does not claim an amplifying circuit, Fig. 1 (not shown), in which networks are used in both the grid and anode circuits of a bank of amplifying vacuum tubes acting in parallel. The Specification as open to inspection under Sect. 91 describes also other vacuum tube circuits including delay networks for amplifying, detecting, demodulating, modulating, and frequency changing. In one arrangement, Fig. 4 (Cancelled not shown), two banks of amplifying valves in parallel are used, each bank having networks in both grid and anode circuits designed to make the vacuum tubes act in parallel. In another arrangement, Fig. 5 (Cancelled) acting as a balanced detector, two banks of vacuum tubes V1 ... V4 and V<SP>1</SP>1 ... V<SP>1</SP>4 are fed in pushpull from a high-frequency transformer TE and retardation lines La1 ... La4, Lag1 ... Lag4 are provided in the anode and grid circuits. The Specification also states that the several vacuum tubes may be enclosed in a single envelope, which may also enclose the retardation lines ; the tubes may have a common cathode. This subjectmatter does not appear in the Specification as accepted.

Filed: 1939-11-01
Abstract: 533,393. Latches. JAMES, J. M. Nov. 1, 1939, No. 29133. [Class 44] To give easy action on closing the door, a sliding latch bolt is moved inwards by the swinging movement of a pivoted member which engages the striking plate, instead of by the usual direct cam action of the striking plate on the bevelled nose of the bolt. The invention is shown applied to a cupboard door. A casing 8 formed from a single bank and having a separate cover-plate 10 is secured to the inner face of the door 2, bolt-guiding spaces being left between the end walls and the cover-plate. The bolt 1 is formed by bending a blank to provide a flat tail and beveled nose. Figs. 5, 6, the tail having terminal lugs 11 which engage the casing wall to limit the extent to which the bolt is shot. The pivoted member 7 has a pair of side wings connected by a bridge-piece 15 which may have an inclined tongue 16. The side members have projections 18 and recesses 19 which respectively engage recesses 14 and projections 13 provided on the edges of the bolt. Member 7 is pivoted in the casing on a pin 17 on which is disposed a spring 22 bearing against bridge-piece to shoot the bolt. Fig. 5 shows the door 2 being closed. The side wings of members 7 engage a striking plate 3 secured on the fixed frame 4 and rock member 7 anticlockwise to retract the bolt, which is shot by spring 22 when plate 3 has been cleared. Release is effected by a push-rod 5 with flanged button 20, 21, disposed in an aperture in the bowed handle 6.

To prepare formyl derivatives a mixed anhydride of formic and acetic acids is used. Examples are given. Alpha - ethyl - beta -(3, 4-dihydroxyphenyl)-alanine is prepared by reacting 3, 4-dimethoxy-phenylacetonitrile with ethyl propionate in presence of sodium ethoxide to give 1-(3,4-dimethoxyphenyl) -1- cyano - butanone -2 (via its sodium salt), heating this with sulphuric acid to give 1-(3,4-dimethoxyphenyl)-butanone-2, reacting this with potassium cyanide and ammonium carbonate in aqueous ethanol to give 5-ethyl -5- (3,4-dimethoxybenzyl)-hydantoin, hydrolysing this with barium hydroxide to give alpha-ethyl-beta-(3,4-dimethoxyphenyl)-alanine, and heating this with hydrobromic acid. Other alpha-alkyl-beta-(3,4-dihydroxyphenyl)-alanines are prepared similarly, substituting other ethyl alkanoates for the ethyl propionate used in the first stage of the above synthesis.  The compounds of the invention, which are stated to have anti-hypertensive properties, may be formulated as tablets with conventional ingredients.  Specifications 936,074, 945,892, 945,893 and U.S.A.
