IPC: D06M15/09
Filed: 1944-04-05
Abstract: 581,938. Coated fabrics for inflatable envelopes. MOSS, W. H. April 5, 1944, No. 6405. [Class 140] A textile fabric for inflatable envelopes is coated with a carbocylic acid ester of cellulose or an ether of cellulose together with sufficient of a sovent of high boiling point to keep the coating flexible but not sticky, the coating being hardened susequently by evaporation of the solvent. In the examples, cellulose acetate is compounded with acetone, ethyl lactate and polyglyceryl acetate and coated on both sides of a fabric envelope, dried in a current of air at 30- 40‹C., the envelope being subsequently erected and the ethyl lactate evaporated off by passing a current of air through the container at temperatures from 30‹ to 100‹C. Benzyl alcohol isopropyl lactate or diacetone alcohol may be used instead of ethyl lactate. The fabric may have been coated first with a dope of cellulose acetate and acetone or, instead of the acetone, methyl acetate, methylene ethylene ether or a mixture of acetone, benzene and ethanol. In making fuel tanks, plasticizers resistant to liquid fuel are used, e.g., dimethyl phthalate, diethyl phthalate di(methoxyethyl) phthalate, triacetin, diethyl tartrate, tri-monochloroethyl phthalate. triacetin, diethyl tartrate, tri(monochlorethyl) phosphate, methyl-phthalyl ethyl glycollate and ethyl phthalyl ethyl glycollate. Pigments, dyes, metallic powders and fillers may be added. The fabric may be of cotton, flax or other natural fibre or regenerated cellulose (high tenacity) or other synthetic fibre not attacked by the solvents in the coating. The cellulose acetate in the dope may be replaced by cellulose propionate, butyrate, acetate propionate, acetate butyrate or acetate stearate, or ethyl cellulose or benzyl cellulose. Suitable high boiling solvents for ethyl cellulose are ethyl lactate, benzyl alcohol cyclohexanol and cyclohexanone.

Title: Process for the preparation of alkylaluminium halides
IPC: C07F5/06
Filed: 1963-02-18
Abstract: Alkyl aluminium halides of formula RmAlpXn, wherein R = C2-4 alkyl group, X = halogen, m and n are each 1, 2 or 3, m+n = 3 when p = 1, and m+n = 6 when p = 2, are prepared by treating a dialkyl aluminium monohydride with an aluminium trihalide and a C2-4 olefin, the olefin and monohydride being present in a molar ratio of 1:1.  This may be done by mixing the dialkyl aluminium hydride with aluminium trihalide, e.g. at 50-100 DEG  C. at atmospheric pressure but preferably 60 DEG  C. and then adding the olefin under pressure, e.g. at 50-100 DEG  C. but preferably 70-85 DEG  C. at 1-20 atms.  A nitrogen atmosphere may be used for the mixing steps whilst the dialkyl aluminium monohydride may be used in admixture with the corresponding trialkyl aluminium.  The alkyl aluminium halides which may be made by this method are the mono-, sesqui- and di-halides, particularly where alkyl is ethyl, propyl, n- and iso-butyl. Suitable reactants are (C2H5)2 AlH+AlCl3+C2H4 and (i C2H9)2AlH+AlCl3+(CH3)2C = CH2. The examples relate to the preparation of diethyl aluminium chloride, bromide and iodide and di-isobutyl aluminium chloride.  The preparation of diethyl aluminium hydride and diisobutyl aluminium hydride from a mixture of AlCl3, Al, H2 and the corresponding olefin at elevated temperature and pressure is also disclosed.

Title: Electronic digital computer
IPC: G06F7/52
Filed: 1955-03-07
Abstract: 802,656. Digital electric calculating-apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION, and RESEARCH CORPORATION. March 7, 1955 [March 5, 1954], No. 6621/55. Class 106 (1). [Also in Group XL (c)] The arithmetic unit of a parallel binary electronic digital computer comprises four single-digit adders, each working on a selected circuit path principle, and three four-stage flip-flop registers, an A register, a B register and an Accumulator register, the stages of each register being, labelled in decreasing order of significance, sign stage, and stages 1, 2 and 3. The four adders each being associated with a particular denomination together receive in parallel form the numbers staticized in the A and Accumulator registers, and on receipt of an add control pulse enter the digits of the sum of the two numbers, in increasing order of significance (lowest denomination first) in stages B sign, Acc 3, Acc 2, and Acc1, and carry from the highest order adder being registered in a carry storage flip-flop and also in stage B3. Each adder, for example adder 2, Fig. 6, receives at gates 40D-43D steady D.C. signals from the corresponding denominations of the A and accumulator registers-A2 and Acc2- and as a result one pair of gates 69D, 61D; 68D, 62D; and 67D, 63D is open. These gates are so arranged that when a pulse is applied to them, from the next lower order adder, on either line C0 or line C1, it passes to that one of the output leads 73D-78D which represents the sum and carry digits of the sum of the digits in the A2 and Acc 2 stages and the carry digit from the next lower order adder. In this manner a pulse passes sequentially through all the adders, its path being determined by the static outputs of the A and Accumulator registers. Associated with the B register is a B sign storage flip-flop which is so arranged that immediately an add control pulse is applied to the lowest order adder the contents of the B sign stage are transferred to the B sign storage flip-flop. Thus upon addition the sign of the number in the B register is not lost, since it is automatically transferred to the B sign storage flip-flop before the lowest denomination digit arrives from adder 3. Several forms of shift are possible in and between the B and Accumulator registers. A simple addition usually being followed by a left shift during which the contents of stages Acc 1, Acc 2, Acc 3, B sign and B sign storage are transferred leftwards resulting in the sum of the adder being correctly positioned in the Accumulator register. Right shift of the B and Acc registers is possible and combined left shift of both the Acc and B registers is possible. Suitable combinations of shifts, additions, and complementations are described for effecting multiplication and division (by a non-restoring method). Specification 802,657 is referred to.
