Title: Improvements in or relating to the treatment of textile materials
IPC: D06M15/423
Filed: 1935-12-12
Abstract: The process of the parent Specification for rendering textile materials resistant to creasing is modified by impregnating the textile materials with a salt of an amine containing a straight or branched carbon chain with more than 5 carbon atoms, and an aldehyde substance or substance yielding an aldehyde, excluding formaldehyde itself, and heating the impregnated material to an elevated temperature.  The amine salt may be a chloride, sulphate, or oxalate. The carbon chain of the amine may be interrupted by other atoms or groups such as oxygen, sulphur, or imino groups. The amines may also contain cyclic or heterocyclic radicles. Soluble salts may be used. In examples, hydrochlorides, sulphates, formates, acetates, lactates, or oxalates of octylamine, dodecylamine, stearylamine, amines from commercial stearic acid, amines from coconut fatty acids, amines from palm kernel oil fatty acids, amines from train oil fatty acids, amines from montanic acids, octylfurfurylamine, glucamine, and phenylstearylamine are used.  The amines may be obtained from the fatty acids by first forming the nitriles and then reducing.  The presence of larger amounts of acids than necessary for formation of the amine salts is avoided.  Acetaldehyde, glyoxal, dimethylol urea, dimethylol formamide, or dimethylol acetone may be used. The aldehyde may be used in aqueous solution or in the gaseous state.  The impregnated textile materials are subsequently treated at temperatures above 100 DEG  C. and preferably between 100 and 200 DEG C.  The treated fibres or fabrics are stable to creasing and of soft touch.  In an example, viscose fabric is impregnated with a solution of stearylamine sulphate and glyoxal in water, and is then heated to 100 DEG  C.  In another example, viscose artificial silk fabric is impregnated with a warm solution of dimethylol urea and hydrochlorides of amines from coconut fatty acids, and then heated at 115 DEG  C.  The Specification as open to inspection under Sect. 91 describes also the use of formaldehyde itself as the aldehyde substance.  In an example, viscose fabric is impregnated with a solution of hydrochlorides of amines from coconut fatty acids, treated with formaldehyde vapours, and then subjected to heating. This subject-matter does not appear in the Specification as accepted.

Title: Condensation products
IPC: A61K47/34
Filed: 1959-10-13
Abstract: The invention comprises urea formaldehyde condensation products containing free hydroxymethylene groups in their molecules, possessing a solubility in water at 20 DEG C. of 0,05 to 0,5% weight/volume and a melting point within the range 120 DEG  to 150 DEG C. The principal recurring unit of the polymer has the empirical formula (C3H6O2N2)n The products can be prepared by condensing urea with formaldehyde in acid aqueous solution to form a precondensate, condensing the precondensate in alkaline medium with a further quantity of urea to form a bactericidal condensation product and removing it from its aqueous solution.  Preferably the first step is carried out at pH 3 to 4, especially 3,7, with about 2 to 3, preferably 2,7 mols. of formaldehyde per mol. of urea.  The reaction mixture, after neutralization, is concentrated and further urea is added to give a final ratio of urea to formaldehyde of between 1,25 and 2,0, preferably about 1,6.  After adjustment to an alkaline pH, suitably 8,0, the second stage of the reaction is effected, suitably by spraying the reaction mixture into a high temperature drying tower, advantageously one with an air space at 180 DEG  to 200 DEG C.ALSO:Bacteriostatic products for phoramacentical purposes comprise as active ingredient ureaformaldehyde condensation products containing free hydroxymethylene groups in their molecules, possessing a solubility in water at 20 DEG  C. of 0.05 to 0.5% weight/volume and a melting point within the range 120 DEG  to 150 DEG  C. The composition may take the form of a dusting powder (with talc or a similar base) or an ointment, suspension, tablets, capsules, syrups or elixirs.  The preparation of the condensation products is described (see Group IV (a)).

Title: Improvements relating to the control of grain size in brittle materials
IPC: C30B1/12
Filed: 1956-11-13
Abstract: <PICT:0856741/III/1> Single crystals are obtained from a material which is non-ductile at atmospheric pressure by subjecting the material to a straining force while under a hydrostatic pressure of 5000 to 15000 atmospheres, releasing the material from the straining force and pressure, and heating the material to a temperature below its melting point.  As shown, applied to germanium, a dumb-bell shaped speciment 16 has one end 16a held in a plug 3 at one end of a cylinder 2 and the other end in a piston 5 movable in the cylinder. The other end of the cylinder is closed by a plug 4 which carries a distance piece 6.  Hydraulic pressure at 10,000 atmospheres is supplied to the spaces 11, 15 on either side of the piston 5 through a valve 7.  When the pressure has attained the desired value the pipeline 12 to the space 15 is shut off from the supply and a pressure relief valve 13 slowly opened, the pressure in the space 11 forcing the piston downwards and stretching the specimen until it meets the distance piece 16, which is indicated by an increase in pressure indicated on a gauge 9.  Pressures in the spaces 15 and 11 are again equalised and, by manipulation of the valves 7 and 13 reduced to atmospheric pressure.  The specimen is then heated to a temperature of 400 DEG C. to 700 DEG C. for 2 to 10 hours.

Title: Wave-signal translating apparatus comprising multiple wave-guide systems
IPC: H01P1/175
Filed: 1955-12-05
Abstract: 783,488. Waveguides. HAZELTINE CORPORATION. Dec. 5, 1955 [Dec. 23, 1954], No. 34807/55. Class 40 (8). [Also in Group XL (c)] In a waveguide apparatus two waveguides having conductive boundaries, in which waves are propagated in the same plane of polarization or in different planes, are coupled together by a waveguide having a non-conductive boundary, in traversing which the wave signal is influenced by means, e.g. a ferromagnetic gyrator, which rotates its plane of polarization. By using an intermediate waveguide having a non- conducting boundary, e.g. one made wholly of dielectric material, a ferromagnetic gyrator mounted therein may be operated by a very high-frequency alternating field, e.g. of 1 megacycle per second. The metallic waveguide member 10, Fig. 1, which receives the signal from a source 14 has portions 13, 15 of rectangular and circular section, respectively. The signal passes from the waveguide member 10 to the metallic waveguide member 11 through a waveguide section 12 comprising a solid cylinder of dielectric material having conical impedancematching ends 24. The plane of polarization of the wave signal is rotated by a magnetic field generated in a ferrite member 26, disposed axially within the waveguide section 12, by a coil 27 energized by pulses from a high-frequency voltage source 28. During the intervals between the pulses the plane of polarization of the signal wave is not rotated, and the signal passes via the impedance matching ends 24, 25, and the portion 36 of the waveguide 11 of circular section, to a rectangular portion 19 and an antenna or other utilizing device 22. During the periods when the pulses are applied to the coil 27 the plane of polarization of the wave signal is rotated through 90 degrees, so that the signal will not be accepted by the portion 19 but passes to a rectangular portion 17 disposed perpendicular to the axis of the section 36 and to an antenna 21 or other utilizing device. An alternative embodiment comprises a waveguide system for feeding a single antenna from which a signal for controlling a guided missile is radiated at reduced power during the initial stages of the flight, and is radiated at full power at a selected time. The reduced radiated signal is obtained by rotating the plane of polarization of the signal through 45 degrees by means of the ferrite device. The first waveguide contains a vane oriented to absorb any reflected signals returned from the final waveguide. Fig. 3 illustrates an alternative construction in which the ferrite member 26b is mounted axially within a waveguide comprising a longitudinal array of radially slotted conductive discs 32 of, e.g., copper, embedded in dielectric material 33. The discs near the ends of the waveguide have reduced diameters to provide impedance matching.

Class 122(v) In a sealing device between a fixed member 111 and a movable member 106, 105, 104, the sealing action is ensured by two series of rings, the first one being provided with at least one gasket 100 having at least a contact surface with said movable member 104 of a spherical zone form, the centre of which is situated on the axis of said movable member 106, the second one comprising packing rings 116, 117, 118 applied upon one of said members or upon parts integral with said members, said two series of rings respectively ensuring the sealing of the rotational and the axial motions of said member, one at least of the contact surfaces of the rings of said two series being provided with recesses (e.g. 102) wherein a lubricating (and/or cooling) fluid is enclosed. The gaskets are applied upon their seats by resilient annular means rotated by the movable member; thus the gasket 101 is applied upon the seat 107, keyed to the rotationally fixed but axially slidable bushing 110, by springs 106a acting between a member secured to the shaft 106 and an axially slidable member 105 which rotates with the shaft. In this embodiment the series of rings providing the seal for axial movement comprise rings 116, 117 and 118 between spring loaded washers 114, 115 which are conically shaped relative to the rings 116 and 117 so that the force of the springs drawing the washers together urges the rings 116 and 118 into contact with the bushing 110, the packing assembly being urged against the ball 112 of the fixed member 111 by springs 113. The rings comprising this packing assembly are cut into segments which are so disposed in the assembly that the slot between adjacent segments is covered by solid parts of the adjacent packing ring.

Title: Improvements in data transmission systems
IPC: H04L25/48
Filed: 1964-08-26
Abstract: 1,063,287. Data transmission. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 26, 1964 [Sept. 20, 1963], No. 34991/64. Heading H4P. A data transmission system comprises means for generating a sequence of pulses corresponding to each input character, and a receiver which derives from the sequence a number of patterns of energization on its output terminals, there being a terminal corresponding to each character. A counting arrangement indicates the terminal which corresponds to the particular character transmitted by indicating the terminal which received the greatest number of zeros. In the system described switches a-e are set up to represent one of ten characters. The switches complete feed-back loops between the stages T1-T5 of a shift register Re and its input via modulo 2 adders m-p. A pulse at Ed starts the register, which develops at its output a sequence of pulses, which repeats until stopped and which represents the input character. At the receiver the sequence feeds a shift register Rr whose stages are connected to various ones of ten modulo 2 adders L0-L9. As the sequence of pulses is received, so a sequence of patterns of energization appears at the outputs of L0-L9. It is shown that that output which is zero throughout the sequence corresponds to the input character. In the event of noise in the transmission channel the sequence will be disturbed and so that terminal which receives the greatest number of zeros is the significant one.

Title: A fuel injection device for internal combustion engines and a method of regulating the same
IPC: F02M59/10
Filed: 1945-12-31
Abstract: 604,343. Fuel-injection pumps. WOOD, G. E. Dec..31, 1945, No. 35180. [Class 102 (i)] [Also in Group XXVII] In a fuel injection pump comprising a member reciprocated by the pressure in the combustion space, the fuel injection is regulated by controlling the escape of liquid trapped by the member. In Fig. 1, the cylinder head constitutes a spring-pressed piston 5 connected to a stem 13 moving in a fixed casing 14 and carries a hollow plunger 18b formed with an injection head 18a maintained closed by a spring 20 situated in a chamber 2 filled with liquid such as engine oil through a non-return valve 4 and having an outlet therefrom controlled by a stop-cock 1. The pressure in the combustion space 6 raises the piston 5 slightly and the fuel admitted through a non-return valve 22 is compressed by the plunger 18b and injected through the injection head 18a, the movement of the piston 5 being controlled by the stop-cock 1 allowing the liquid compressed in the chamber 2 by the stem 13 to escape. The casing 14 is held in a screwed ring 15a carried on legs 15 secured to a ring 15b bolted to the engine cylinder, and the initial position of the piston 5 is adjusted by means of a stop 21. Liquid ejected past the stop-cock 1 may pass through a non-return valve to the engine sump or hydraulic accumulator, or alternatively may be returned through the stop-cock on the return stroke of the piston 5, by a spring- loaded plunger in the outlet passage, a non- return valve in parallel with the stop-cock, facilitating the return flow. In a modification for use with a conventional cylinder head, the slidable piston moves in a body adapted to be screwed to the engine cylinder. A governor may control the stop-cock, and in a multicylinder engine the stop-cocks may be conjointly controlled.
