Filed: 1951-02-22
Abstract: 707,996. Making composite sheets. KINNEY, J. Feb. 22, 1951 [Aug. 9, 1950], No. 4320/51. Classes 83 (2) and 83 (4) Jointing by rolling.-A method of producing multiply metal strip or sheet of copper and a stainless metal such as stainless steel from rolled plates of the metals comprises cleaning the surfaces of the plates, placing them with the cleaned surfaces together, forcing the surfaces into gas-excluding contact while sealing the marginal edges by welding and then heating and pressing or rolling to bond the metals. After bonding the welded edges are sheared off and the composite sheet hot or cold worked as required. Fig. 3 shows an assembly of a copper plate 7 between two stainless plates 8, the contacting surfaces having been cleaned and rendered oxide free. The plates are commercial 'rolled plates, the assembly being about inch thick. The plates are pressed together in a vertical position at about 40 pounds per square inch, the force being applied to the plates at the centre so that gas-excluding pressure is first applied to the central zone of the assembly. The edges of the stainless plates, which are slightly larger, are then welded together around the copper plate, the assembly heated to between 1650‹ F. and 1950‹ F. and the plate bonded by pressing or rolling, for example by rolling at 175 feet per minute so as to reduce the thickness by about 3 per cent. The assembly may comprise two plates only.

Title: Improvements in or relating to methods of dry-spinning aqueous solution of albuminous substances
IPC: D01F4/00
Filed: 1943-03-17
Abstract: <PICT:0569662/IV/1> Artificial threads are produced by extruding an aqueous solution of an albuminous substance through a nozzle F into a spinning shaft, the upper part of which is a thermostatically-controlled chamber A containing air saturated with water vapour at a temperature which is approximately the mean of the appropriate spinning interval, and through the middle D and lower parts C and B of which a counter-current of cold or warm air is passed.  The threads are finally collected by the device E.  The lower portion B of the shaft is heated, whilst the portion C is heat insulated. The velocity of the air current may be varied by adjusting the width of the air exit immediately below the chamber A.  The temperature limits of the spinning interval depend upon the kind and ageing of the albumen employed, the concentration of the spinning solution and additions which have been made thereto. Numerous examples indicating the appropriate spinning intervals and conditions for particular spinning solutions are given.

Abstract: 857,453. Travelling wave-tubes. MONOGRAM PRECISION INDUSTRIES Inc. Feb. 12, 1957 [Feb. 16, 1956], No. 4696/57. Class 39(1). The interdigitated delay line of a travelling wave tube, especially a backward wave oscillat- or, comprises a hollow waveguide having two continuous internal diametrically opposite longitudinal ridges 9, 9<SP>1</SP>, Fig. 2, 18, 18<SP>1</SP>, Fig. 3, and flat rectangular teeth 9<SP>1</SP>, 9<SP>11</SP>, 18<SP>1</SP>, 18<SP>11</SP>, spaced along the ridges and projecting beyond the axis, the teeth and ridges being integral with the hollow body and being of electrically conductive material, the width of the teeth and ridges being equal. The structure is preferably built up from a plurality of laminations all which have diametrically opposite inwardly projecting stubs forming the two ridges, from alternate ones of which the delay line fingers extend. The delay line fingers have aligned apertures for the passage of the electron beam. The laminations are held within and by metal/or glass/tube 28 which may be the tube envelope or can fit inside a tube envelope of convenient diameter or the laminations are brazed or soldered together. The laminations are of copper or silver or silver plating on a copper punching. After assembly, the inside of the waveguide can be coated with silver. The laminations 11-15 near the middle of the delay line may be of lossy material e.g. Fe, or coated with lossy material. Each wafer has 2 slots 28<SP>1</SP>, Figs. 2, 3 receiving ribs 28<SP>1</SP>, 28<SP>11</SP> pressed or rolled in tube 28, to ensure correct angular alignment of the laminations. A magnet coil can be wound round tube 28 or a permanent magnet can be used. The width of the pass band depends on the spacing of the teeth and hence on the thickness of the teeth. Odd and even laminations may be of different thicknesses and to increase the thickness of and spacing between the laminations each lamination can be made up of two or more laminations stacked together. The odd and even groups of laminations need not contain the same number of laminations in all cases above odd and even referring to those laminations which have fingers and those which have no fingers. In a modification, Figs. 4, 5 (not shown), the beam passes through slots open at one end in the interdigitated teeth. The ridges increase the dispersion (rate of change of phase velocity with frequency) and so increases the electronic tuning range, and also increase the mechanical strength of the structure. The laminations are punched out of sheet metal, only two punching dies being required for the respective laminations with and without fingers.

Title: New basically substituted nicotinic acid amides
Filed: 1952-02-22
Abstract: The invention comprises nicotinic acid amides of the general formula <FORM:0699560/IV (b)/1> where Alk represents an alkylene radical containing from 2-4 carbon atoms and Am represents a dialkylamino radical containing not more than 9 carbon atoms in all or a N-piperidino, N-morpholino, or an N-piperazino radical.  These compounds are prepared by first reacting a base of the formula <FORM:0699560/IV (b)/2> with a reactive compound which contains the nicotinic acid radical, such as nicotinic acid itself or its halide, anhydride or lower alkyl ester.  An alternative method of preparing the compounds of the invention is to react nicotinic acid-(1 : 2-diphenyl-ethyl)-amide with a reactive ester of a basic alcohol Am-Alk-OH in the presence of an acid binding agent such as sodium amide, lithium amide, sodium and potassium.  If the compounds of the invention are reacted with a quaternizing agent such as an alkyl or aralkyl halide or sulphate or alkyl sulphonate in equimolecular proportions a quaternary salt of the N-atom of the basic side chain is obtained.  If an excess of the quaternizing agent is used a di-quaternary salt is obtained, the N-atom of the pyrdine ring also being attacked.  The compounds of the invention form salts with organic or inorganic acids.  In examples (1) N-(21-diethylaminoethyl)-N-(1 : 2-diphenylethyl)-amine and nicotinic acid anhydride are reacted in the presence of potassium carbonate to give nicotinic acid[N-(1 : 2-diphenylethyl) - N - (21 - diethylaminoethyl)] - amide; (2) the compound of example (1) is also obtained by refluxing nicotinic acid-1.2-diphenylethyl)-amide with dimethylaminoethyl chloride in the presence of sodium amide; (3) nicotinic acid-(1 : 2-diphenylethyl)-amide is refluxed with b -morpholino ethyl chloride in the presence of sodium amide to give nicotinic acid-[N -(1 : 2 - diphenylethyl) - N - (21 - morpholino - ethyl)] amide; (4) N-(1 : 2-diphenylethyl)-N-(21-piperidinoethyl)-amine is reacted with nicotinic acid anhydride in presence of potassium carbonate to form nicotinic acid-[N-(1 : 2-diphenylethyl) - N - (21 - piperidinoethyl)] amide; (5) the product of example (1) is reacted with methane sulphonic acid methyl ester to form the corresponding quaternary salt; (6) in a similar way the quaternary iodo methylate of the product of example (1) is formed; (7) the dimethiodide of the same compound is formed.  Other N-substituted nicotinic acid-(1 : 2-diphenylethyl)-amides mentioned are the 31-diethylaminopropyl compound, the 31-dimethylaminopropyl compound and the 21-dimethylaminoethyl compound.

Abstract: 285,812. I. G. Farbenindustrie Akt.- Ges. Feb. 21, 1927, [Convention date]. Azo dyes.-Disazo dyes are obtained either by coupling 1 mol. of a tatrazotized diamine containing carboxyl groups in o-position to the amino groups with 2 mols of an acetoacetarylide sulphonic acid, or by coupling 1 mol. of a diazotized p-nitroamine containing a carboxyl group in o-position to the amino group with 1 mol. of an acetoacetarylide sulphonic acid and converting the resulting monoazo dyestuff into a disazo dyestuff by reduction followed by treatment with phosgene, thiophosgene, or carbon disulphide. The products yield on cotton or viscose silk clear yellow, orange, and brown shades fast to light, and the dyeings may be after-treated with metallic salts. The following examples are specified. (1) The product obtained by coupling 1 mol. of tetrazotized 4 : : 4<1>-diaminodiphenylurea- 3 : 3<1>-dicarboxylic acid with 2 mols. of acetoaceto-chloranilide sulphonic acid (Specification 307,531) in alkaline solution yields on cotton or viscose silk greenish-yellow and pure yellow dyeings respectively which are rendered very fast on treatment with copper salts. (2) The product obtained by coupling 1 mol. of tetrazotized 4 : 4'- diaminodiphenyl-3 : 31-dicarboxylic acid with 2 mols. of acetoacet-1-naphthalide disulphonic acid in alkaline solution yields on cotton and viscose silk yellow and orange-yellow dyeings respectively which become brownish-yellow on treatment with copper salts. (3) The nitro group of the monazo dyestuff 5-nitro-2-aminobenzoic acid ->(alkaline) acetoacet-o-anisidide sulphonic acid is reduced, and the product is treated with phosgene, the resulting disazo dyestuff yields on cotton and viscose silk golden yellow dyeings which become pure yellow on treatment with copper salts. If the phosgene is replaced by thiophosgene or carbon disulphide the dyeings are yellowish-brown becoming brown on treatment with copper salts. Specifications 198,398, 198,634, and 215,769 are referred to. Acetoacet-1-naphihalide disulphonic acid is made by sulphonating acetoacet-1-naphthalide.
