Granted: 1953-12-01
Abstract: A foil, film or the like of a fatty acid ester of cellulose which contains more than 1.5 but less than 3 molecules of combined fatty acid per glucose residue is subjected to superficial saponification in a bath containing an alkaline substance and an organic solvent, and when the saponification has proceeded to the desired depth the foil or other article is treated in one or more baths which terminate the saponification, at least one of these after-treatment baths being one which contains no aqueous solution of monobasic or dibasic acid but which is capable of reducing aqueous swelling of partially esterified cellulose having 0.5 to 1.5 molecules of combined fatty acid per glucose residue.  Such an after-treatment bath may be a solution of a water-soluble sulphate, phosphate, sulphite, thiosulphate, carbonate, tartrate, citrate, acetate, lactate, fluoride or chloride.  It may be an aqueous solution of a tribasic acid or of glycerol, glucose or a sugar.  It may be a primary saturated alcohol having a straight chain of 4-11 carbon atoms, such as butanol-1.  An after-treatment bath containing toluene, benzene, tetrahydronaphthalene or a liquid ether may be used.  The treated films may be used for photographic purposes, e.g. the saponified layers may be impregnated with light-sensitive substances.  If desired, plasticizers originally present in the films may be removed from the saponified layers by solvent treatment, e.g. by treatment with aqueous or alcoholic-aqueous solutions of dispersing agents such as salts of sulpho-ricinoleic acid, sodium oleate, sodium p-octylbenzene sulphonate, dodecylamine hydrochloride and lauryl ethers of polyethylene oxide.  The substance for reducing aqueous swelling and the solvent for the plasticizer may be incorporated in a single treatment bath.  In an example, a cellulose acetate tape is passed in succession through a solution of caustic potash in aqueous methanol, through two baths of butanol-1, through an aqueous solution of phosphoric acid and through two baths of circulating water.

Abstract: 1,226,113. Ignition systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 23, 1968 [April 26, 1967], No.19153/68. Heading F1B. [Also in Division H3] A train of high voltage pulses is supplied to a sparking plug at 5, each time a switch 25 is opened, by a secondary winding 4 of a transformer 3 whose primary 2 is in series with a capacitor 1 which is repeatedly charged (by diodes 16, 17), and discharged by an SCR 18; the circuit controlling the SCR 18 being responsive to a control signal (the opening of the switch 25) and to a voltage dependent upon the capacitor voltage at any time (and derived via resistor 21). The switch 25 is controlled by an engine, whose spark plugs are fired by the secondary 4, and provided the switch is open, a sufficiently positive potential on the capacitor 1 causes transistor 19 to turn off, transistor 26 to turn on, and the SCR 18 therefore to conduct. An oscillator comprising a transistor 7 and a transformer 9, 10, 11 supplies a voltage doubler 15, 16, 17 to charge the capacitor 1. Successive charging and discharging of C1 occurs until the switch 25 closes. Each pulse causes the capacitor 1 and primary 2 of transformer 3 to resonate, the SCR 18 conducting alternate half cycles of the damped oscillation, and diodes 16, 17 the other half cycles, so that if the recovery time of SCR 18 is greater than a half cycle at the natural frequency of L2C1, each h.v. pulse will cause a series of damped oscillations. The switch 25 may be replaced by an engine-driven magnet co-operating with either a coil, or a Hall effect device. In a first modification Fig.2, (not shown), a two-transistor oscillator is used (7, 7<SP>1</SP>) and is connected to a bridge rectifier 15<SP>1</SP>; and the transistors 19, 26 are arranged as a complementary pair with a time delay circuit (32-37) in the base circuit of one transistor 19, to ensure continuing conduction of the SCR 18 during the damped oscillations of the resonant circuit (1, 2 etc). In a second modification Fig.3 (not shown) the complementary pair (19, 26<SP>1</SP>) is rearranged and the switch 25 is replaced by a photo-resistor responsive to light from a lamp (40) passing through an apertured disc 43, also Fig.4, (not shown) driven by the engine. In a further modification Fig. 5, (not shown), the photo-resistor is replaced by a photo-transistor (38<SP>1</SP>) which, with several additional transistors which increase amplification and sensitivity of the device, are built as an integrated circuit (50). The lamp intensity and the sensitivity of the photo-resistor or photo-transistor are variable in accordance with engine parameters for automatic ignition control.

Abstract: 1,226,126. Data processing. GENERAL ELECTRIC CO. 11 July, 1968 [14 July, 1967], No. 33071/68. Heading G4A. An arithmetic unit performing floating-point division calculates an initial quotient exponent value, subtracts divisor mantissa from dividend mantissa, produces a quotient mantissa bit, and increments the quotient exponent if the divisor mantissa is less than the dividend mantissa. Floating-point division.-The divisor exponent is subtracted from the dividend exponent using complemented addition and the exponent portion of a parallel binary adder having separate exponent and mantissa portions. The mantissas are now shifted left until normalized. If the dividend mantissa becomes normalized before the divisor mantissa, the quotient exponent is incremented (in the adder) for each remaining divisor bit-shift. If the divisor mantissa becomes normalized before the dividend mantissa, a quotient bit of 0 is generated for each remaining dividend bit-shift. The mantissa division algorithm involves adding/subtracting the divisor mantissa to/from the mantissa dividend and subsequent partial remainders using the adder, with partial remainder shift, including shifting over strings of l's and 0's when dividend or partial remainder is negative and positive respectively, the algorithm starting with a subtraction which generates a quotient bit and detects whether the divisor mantissa is greater than the dividend mantissa and if it is not the quotient exponent is incremented by one. The number of mantissa quotient bits generated in the whole algorithm is controlled by a count successively incremented using the adder exponent portion. The result is finally normalized. Any attempt to divide by zero is detected.

Abstract: 1295881 Spirally wound tube IMPERIAL CHEMICAL INDUSTRIES Ltd 9 Feb 1970 [25 Feb 1969] 9957/69 Heading F2P [Also in Division B2] A method for producing spirally wound tubes comprises winding at least two plies at an acute angle to a mandrel, at least one having a coating of a fluid foamable plastic composition, these being wound such that the foam lies between two plies, allowing the foam to set and harden and removing the tube from the mandrel when the foam has set sufficiently. As shown, two plies 4a (inner) and 4b (outer) are separated by the foam layer. The inner ply is wound on to the mandrel 1 and adjacent helices overlapped and covered with adhesive tape 7 (adhesive, the setting foam or heat, when 4a is of plastics, may also be used). The mandrel shown corresponds to that disclosed in Specification 1,295,472, an air cushion between the mandrel and inner ply, air being supplied via the hollow mandrel and pores in its surface (Figs. 3a, 3b, 4, not shown). The foam is spread on to the outer ply within housing 18 by means of a nozzle transversely and longitudinally movable relative to the ply 46 (Fig. 2, not shown). The angle at which the outer ply is supplied to the mandrel is adjusted by a wheel 31. The plies are drawn from spools 3a and 3b by rollers 5, 6, 8 and 9 and tension is maintained in the foamed ply by rollers 10 and 11. The wound tube is advanced by a continuous belt 36 passing over skew rollers 37, 38. When sufficiently set the pipe is removed from the mandrel and cut into lengths by a flying saw (not shown). The plies may be of paper, cardboard, textile materials, metal and plastics. The plies may be waterproofed, e.g. a glass fibre ply may be impregnated with a thermosetting resin. Thermoplastic plies may be of olefin polymers, vinyl chloride polymers, polyamide or polyester and may be extruded in situ. Longitudinal reinforcement of the tube may be included, being of steel, glass fibre, synthetic or carbon fibres. The foams are preferably based on curable polymer systems, e.g. polyurethanes, phenolformaldehyde and urea formaldehyde resins, foams based on polymerizable vinyl ethers and foams based on polyisocyanurates. Such pipes may be used for sewage, soil pipes, insulation and air ducting.
