Title: A process for the manufacture of a cotton fabric coated with a polyamide
IPC: D06M15/59
Filed: 1962-03-05
Abstract: A textile material is coated with a polyamide by treating a napped cotton fabric with a solution of a polyamide in formic acid and precipitating the polyamide from the solution on to the fabric, and thereater washing the treated product, wherein the polyamide solution contains a dispersed, sulphited, unsaturated oil or fat in an amount greater than the amount of the polyamide in the solution, and wherein the oil or fat is at least partially removed from the fabric by washing, after the coagulation of the polyamide has been effected. The cotton fabric may have a weight of 150-300 grammes per square metre, e.g. 175-225 grammes per square metre.  The sulphited unsaturated oil is a sulphited fish oil.  The concentration of the sulphited unsaturated oil in the polyamide solution is twice the concentration of the polyamide. The polyamide solution is a 10% solution of polyamino caproic acid in aqueous formic acid containing 85% formic acid.  The treated textile material may be ground after treatment with the polyamide solution and before drying.  The textile material may be treated with an alkaline solution after grinding and prior to drying.  The fabric may be treated with an amount of polyamide solution such that the treated fabric contains from 20 to 35% by weight, and preferably 30% by weight, of polyamide.  The cotton fabric is provided on at least one side with a discontinuous porous layer of a polyamide.  The product may contain at least 2,5% by weight of a sulphited unsaturated oil.  Sulphited oils which may be used are, for example, sulphited sperm, coconut, linseed and other oils having an iodine number higher than 100.

IPC: B60N2/16
Filed: 1970-02-21
Abstract: 1282193 Resiliently mounted seats UNIVERSAL OIL PRODUCTS CO 19 April 1971 [21 Feb 1970] 8426/70 Heading A4U [Also in Division F2] A seat comprises a base part 4, a seat part 6, supported from the base part for vertical movement against a resilient bias, and a piston and cylinder vibration damper 2 interposed between the parts 4 and 6 by a linkage which increases the damping effect with increasing vertical reciprocaion of the seat part from its ride position, i.e. midway between up-stop and down-stop positions. The damper is pivoted at 5 to the base part and to an arm 8 which is pivoted at 9 to the base part and, at its other end, to the seat part by a vertical link 10 which on rise or fall of the seat moves the damper and the arm 8 from a collinear and approximately horizontal position, which they assume when the seat part is in ride position, to withdraw the piston from the cylinder, small vibrations about the mid point causing the application of minimal damping effect and larger vibrations increasing damping.

Title: Improvements in or relating to rolling mills
IPC: B21H1/06
Filed: 1942-06-19
Abstract: 553,649. Rolling rings. BAKER, S. E. June 19, 1942, No. 8433. [Class 83 (iv)] Relates to mills, for rolling rings, of the type having an inside roll a, an outside roll b, two conical edging rolls c, d and two guide rolls g, h for rounding up the rings, and consists in providing additional conical rolls e, f to restrain the ring from buckling during rolling and from moving out of the pass of the rolls c, d. The upper roll g is of larger diameter than the lower roll h and after the diameter of the blank has been increased sufficiently for the blank to come into contact with these rolls, they are retracted through equal distances and this is stated to result in raising the centre of the blank. In a modified method of controlling the rolls g h, the roll h, Fig. 7, is kept in contact with the work by a constant pressure cylinder 2. Should the work tend to move to the right out of the pass of the rolls c, the rollers 3 on the lever 4 follow it causing pressure to be admitted to the cylinder 1 in a direction to force the roll g to the left thus forcing the work downwards so that as rolling proceeds it will regain its position in the pass of the rolls c.

Title: Method of treating coal
IPC: C10L9/10
Filed: 1931-03-19
Abstract: 372,038. Preparing fuel. DELAWARE, LACKAWANNA, & WESTERN COAL CO., 120, Broadway, New York, U.S.A.-(Assignees of Mork, H. S. ; Brookline, Massachusetts, U.S.A.) March 19, 1931, No. 8474. Convention date, March 19, 1930. [Class 50.] Multi-coloured or " rainbow effects are produced on coal by bringing it into contact with solutions from which a thin adherent film is deposited by chemical or physical reactions. Examples of treatment are described involving the chemical reduction and oxidation of the solution and the deposition of the colour from colloidal solutions. Thus the coal may be immersed in a bath consisting of 2¢ lb. of ferric chloride and 3 lb. of potassium or other alkali ferricyanide dissolved in 100 gallons of water, and the temperature and time of immersion varied to secure a predominance of orange and yellow or blue and violet in the film of Prussian blue or related compound produced by reduction of the solution. Compounds such as chromates and bichromates may be added to maintain the stability of the bath. Reactions having an apparent oxidizing effect on the bath comprise treatment with dyes such as Ciba blue 2B and Sulphur Navy Blue GL with caustic soda and sodium hydrosulphite. An example of a colloidal solution from which a coloured deposit is obtained comprises an aqueous solution of ferric chloride containing a very small quantity of hydrochloric acid and heated until a slight opalescence appears.

Title: Improvements in frequency demodulation
IPC: H03D3/04
Filed: 1940-05-13
Abstract: 539,254. Frequency demodulation copying telegraphy. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 13, 1940, No. 8574. Convention date, May 22, 1939. [Classes 40 (iii) and 40 (v)] Frequency modulated signals are converted into amplitude variations by a valve circuit having two states of stability which is triggered from one state to the other by successive half-cycles of the received wave, thereby producing constant-amplitude unidirectional pulses varying in frequency in accordance with the received signal, and integrating the pulses to produce an average current varying in amplitude in accordance with the frequency variations. The frequency modulated signals, which may be used for facsimile transmission and vary in frequency from 1,600 to 2,000 c.p.s., are applied in push-pull to gasdischarge valves 18, 23, so connected that one valve is tripped by one half-wave and passes current until the other valve is tripped by the succeeding half-wave and de-energizes the first. Each time a valve 18 (or 23) passes current, a condenser 34 (or 37) is charged by current through the valve 18, and resistance 35, and subsequently discharges through resistances 35, 20, 19. During the charging of the condensers 34, 37, positive pulsating voltage pulses are applied through a rectifier 39 to a resistance 42, these voltages being amplified by valve 46 and then smoothed by a filter. Two pulses will pass through the resistance 42 for each complete cycle of the signal current, these pulses being of constant amplitude but varying in frequency with the signal. The average current in the resistance 42 is dependent on the number of pulses per second and thus varies with the frequency. The timeconstant of the condensers 34, 37 is such that they can charge or discharge completely within a halfcycle of the highest frequency. The condenser 33 and resistances 20, 24 are so chosen that when one valve 18, say, is tripped, the other 23, is deenergized by a momentary rise of its cathode voltage.

Abstract: 1,179,085. Centrifugal classifier. DONALDSON CO. Inc. 26 Feb., 1968 [18 April, 1967], No. 9159/68. Heading B2P. A classifier, in which powdered solids are classified according to size in a rotor by the opposite actions of centrifugal force and an inwardly flowing air current, comprises a housing 11 having a ring portion 16, a rotor 12 mounted for rotation within the ring portion with a gap 28 therebetween, the rotor having a cavity 33 in communication with the gap, means 55-57 for rotating the rotor to produce an air vortex in an elutriation zone in the cavity adjacent the periphery of the rotor, an inlet passageway 50 in the housing for the supply of elutriating air, an inlet passageway 70 for supplying solids to be classified to the elutriating zone, an opening 35 in the rotor in communication with the cavity 33 through which the air and a fine reaction of solids are discharged, and an outlet passageway 72 in the housing in communication with the gap 28 positioned forwardly of inlet passageway 70 relative to the direction of rotation of the rotor for receiving from the elutriating zone a coarse fraction of the solids. The rotor 12 comprises rings 25, e.g. of triangular cross-section, which define between them a converging passage terminating in a radial annular passageway 29 in communication with gap 28 and which are clamped between circular plates 30, 31 enclosing the cavity 33 in which are mounted a number of radially extending fins 65 which when the rotor is rotated produce the air vortex. The rings 25 may not be present. The opening 35 communicates via rotatable conduit 36 connected to the rotor and a stationary conduit 46 to a filtering bag 47 for collection of the fine fraction. The conduit 36 is mounted in bearings 40 and is rotated through bevel gearing 55, 56 by means of a variable speed electric motor 57 controlled by a rheostat 59. Air seals are provided at 44 and 45. Elutriating air is supplied through two passageways 50 either by means of vacuum-producing means connected to conduit 46 or by means of a supply of pressurized air connected to a conduit 51. The powdered solids to be classified are injected through a conduit 73, the passageway 70, gap 28 and passageway 29 into the cavity 33 where they are dispersed by the air also entering the cavity 33 along the rotor periphery. Because the coarse fraction outlet passageway 72 is located forwardly of the solids inlet 70, the unclassified solids are eventually dispersed as discrete particles on which the vortex acts to produce fine and coarse fractions. The coarse fraction outlet passageway 72 is connected to a coarse fraction collection system, Fig. 1 (not shown), which includes aspirating means for producing a flow of air and coarse fraction from the chamber 33 of the rotor, an air return passageway 71 in communication with the gap 28 and a coarse fraction receiver in communication with the gap 28 and a coarse fraction receiver in communication with the passageways 71, 72.
