Abstract: 738,605. Digital electric calculating-apparatus. BRITISH TABULATING MACHINE CO., Ltd. Oct. 14, 1953 [Feb. 5, 1953], No. 3259/53. Class 106 (1). Electronic apparatus for adding two serial trains of binary-coded pulse groups comprises a first adding means 3 for producing the sum of two binary pulse groups, a second adding means 2 for adding a filler digit to the first sum, gating means 9, 11 controlled by the occurrence of a carry at the end of a pulse group in either adding means, for selecting the sum pulse train from either the first or second adding means, and means for entering an end of pulse group carry from the second adding means into the first adding means. The binary adders 2 and 3 are of the type described in Specification 738,269. One of the numbers to be added is fed from a shifting register 1 to the adder 3 while the other number enters this adder on a line 5. To provide an undelayed sum digit output for application to the second adder 2, a coincidence circuit 19 is used to compare the digit entering the adder 3 from the register 1 with the setting of the coincidence and anticoincidence circuits in the adder. The coincidence circuit 19 controls a Schmidt trigger circuit 20 which provides one entry to the second adder 2; " filler " digits are entered on line 6 from a shifting register 21 or, in the case of non-uniform items, a magnetic drum store is preferred. Carry storage triggers 13 and 12 for adders 3 and 2 respectively, control gates 14 and 15 which also receive clock pulses on a line 16. After each binary pulse group, if a carry has been registered in either of the storage triggers 13 and 12 a trigger 17 is set to open a gate 11 and allow the result from the adder 2, including a " filler " digit, to be fed back to the shifting register 1. On the other hand, if no carries have been registered, the trigger 17 is set to open the other gate 9 and allow the sum from the adder 3 to be fed back. If a carry is registered in the trigger 12 but not in the trigger 13, a carry is subsequently entered in the latter via a diode shifting circuit 18 operated by a pulse from the line 16. Delay units 8 and 10 are provided to allow time for selection of the appropriate pulse group from the adders 3 and 2. Specification 678,427 also is referred to.

Title: Method for the preparation of a hydrophilic polymer
IPC: A23L29/288
Filed: 1967-07-26
Abstract: 1,205,765. Preparation of hydrophilic polymers. NATIONAL PATENT DEVELOPMENT CORP. 26 July, 1967 [5 July, 1967], No. 3696/70. Divided out of 1,205,764. Heading C3P. [Also in Division A5] Hydrophilic polymers in the form of finely divided spheres or beads are prepared by rapidly agitating a water-soluble polymerizable monoester of an olefinically unsaturated carboxylic acid having at least one hydrophilic functional group in the alcohol moiety of the monoester in a non-polar liquid suspending medium in which the monoester and the polymer formed are insoluble, the agitating being effected in the presence of an amount of a free radical vinyl polymerization catalyst sufficient to polymerize the monoester. Suitable suspending media include silicone oils, and paraffinic and/or aromatic hydrocarbons, e.g. mineral oils and xylene. Polymerization can be effected in the presence of a minor amount (relative to the monoester) of a cross-linking monomer. Also, the polymers obtained can be mixed with further monoester, and catalyst and with cross-linking monomer to form a casting composition which can be cured to form shaped articles. The monoester is preferably a hydroxyalkyl acrylate or methacrylate, e.g. a hydroxypropyl or 2- hydroxyethyl (meth)acrylate; and the optional diester is suitably a diacrylate or dimethacrylate, e.g. a dimethacrylate of ethylene glycol, 1,3 - butylene glycol or 1,4 - butylene glycol. Polymerization catalysts specified are isopropyl percarbonate, t-butyl peroctoate, cumene hydroperoxide and benzoyl peroxide. The polymer beads can be used to form shaped articles, e.g. by injection moulding, extrusion or calendering. The polymers can also be adhered to metal, glass, rubber, plastics and other surfaces, and can be formed and ground into toric contact lenses. When used in dental applications, an amine polymerization accelerator can be included in the casting syrup. The hydrophilic polymers formed are also useful in body implant applications and in medicinal, flavouring and fragrance compositions. Other uses include cigarette filter elements or tips, filter media, chromatographic filters, thickening agents in foods, bandages and dressings, nutrient carriers, and light-transmitting coatings.

Title: Improvements in or relating to the finishing of moired fabrics
IPC: D06Q1/08
Filed: 1941-03-20
Abstract: 548,053. Treating textiles with liquids. BRITISH CELANESE, Ltd. March 20, 1941, No. 3812. Convention date, March 22, 1940. [Class 15 (ii)] A thin film of resin is deposited on a moired fabric prior to a finishing treatment, e.g. with oils or other substances which improve the handle and fullness. The treatment with resin removes or diminishes the tendency of the originally clear and bright highlights of the moire pattern to be dimmed during the finishing treatment. The moire effects may be produced on ribbed fabrics by heat and pressure, or on plain or satin weave fabrics by engraved rollers under heat and pressure. Silk, linen, cellulose ester, or cellulose ether fabrics or fabrics containing cellulose derivative fibres together with cotton, linen, silk, or regenerated cellulose fibres, may be treated. The resins used may be natural or synthetic, e.g. copal, colophony, kauri, dammar, mastic, sandarac, shellac, copaiba, glycerol-phthalic anhydride resins, coumarone, vinyl acetate, thio-urea, crotonaldehyde, furfural, and ester-gum resins. The resin may be applied as a dilute solution in an organic solvent which does not damage the fabric under treatment. Benzene, toluene, xylene, carbon tetrachloride, dichlorethane, chlorbenzene, trichlorethylene, butyl, amyl, and hexyl acetates, and butyl, amyl, and hexyl propionates, are specified solvents. The resin solution may be applied by immersion, padding, or roller methods. The solvent is removed by evaporation. In an example, cellulose acetate fabric is treated under heat and pressure with a ribbed pressure surface to produce a bright peimanent moire pattern. It is then damped with a very dilute solution of colophony in carbon tetrachloride. Excess of resin solution is removed by passing the fabric between pressing rollers. The solvent is evaporated by passing the fabric through a heated chamber. A finishing agent, e.g. sulphonated olive oil or a mineral oil is then applied by padding or by passing between partially immersed rolls. The finishing oil is usually applied in the form of an aqueous solution or dispersion.
