Title: Improvements in and relating to polymerisation
Filed: 1959-09-22
Abstract: The invention relates to polymers of alkenyl ethers of 2, 3-epoxycyclopentanol, such as the vinyl, allyl and crotyl ethers. The initial polymerization may involve the alkenyl group and this initial polymer may be hardened at a later stage by cross-linking through the epoxy group.  The ether may be copolymerized with other monomers, such as vinyl chloride, bromide or fluoride, acrylonitrile or methacrylonitrile, vinyl acetate, butyrate, chloroacetate, formate or caproate, vinylidene chloride, bromide or fluoride, chlorostyrene, acrylic or methacrylic esters, acrylic or alk-acrylic acids, butadiene, isoprene, and various substitution products of butadiene; acetylene, alkyl acetylenes, dimers or trimers of acetylene, unsaturated esters of polybasic acids such as the divinyl, diallyl or dimethallyl esters of oxalic, maleic, malonic, citric or tartaric acids, the phthalic acids or naphthalene dicarboxylic acids, unsaturated ethers or esters of polyhydric alcohols such as ethylene glycol, trimethylene glycol, glycerol, mannitol or sorbitol, e.g. the vinyl, allyl or methallyl ethers or the acrylic or methacrylic esters, or silicon compounds such as vinyl triethoxy silane.  The polymerization may take place in bulk, suspension or emulsion (e.g. using hydroxyethyl cellulose or sodium sulphosuccinate as emulsifiers), or in solution (e.g. in acetone, tetrahydrofuran, dimethylformamide or benzene).  The catalyst may be acetyl, benzoyl, acetyl benzoyl or lauroyl peroxide, t-butyl hydroperoxide, perbenzoate or peracetate, cumene hydroperoxide, potassium persulphate or azo-bisisobutyronitrile.  The polymers may be dissolved in a solvent, such as methyl isobutyl ketone, xylene, toluene, cyclohexanone, benzene or dimethylformamide and used as a coating composition, optionally in the presence of aids for the subsequent cure, such as polyphenols, polyamines, and polybasic acids, e.g. phosphoric, aconitic, citric, tricarballylic, oxalic, succinic, glutaric or adipic acid.

Abstract: 986,729. Diode switching circuits; circuits employing bi-stable magnetic elements. SIEMENS & HALSKE A.G. Aug. 19, 1963 [Aug. 20, 1962], No. 32628/63. Headings H3B and H3P. In a magnetic storage or relay-operating matrix, each row and column conductor is in the form of a transmission line terminated by a resistance equal to the characteristic impedance and is energized from the secondary winding of a transformer, the primary of which is energized from a diode switching matrix. Fig. 1 shows a ferrite core storage matrix in which each row conductor Z1 . . . Z4 and each column conductor (not shown) is energized by the secondary winding of transformers U1 . . . U4 connected to the cross points of a diode switching matrix. In order to read from one core of the row Z1, switches SL1, SL4 are closed, giving a current via diode D2 in the primary of transformer U1. A pulse is thus induced in the secondary of U1 and transmitted along the row conductor Z 1 and dissipated in the termination resistor R1. The appropriate core is selected by switching the appropriate column conductor (not shown). Switches such as SS1, SS4 are closed to provide a writing current via diode D1. Terminating resistors R1 . . . R4 prevent spurious pulses in the various conductors due to reflection at mismatched terminations. In Fig. 2, two terminating resistors R11, R12 are used for all the row conductors Z1 . . . Z4, R11 being connected in circuit by diodes such as D11, D13 during readout and R12 being connected by diodes such as D12, D14 during writing pulses.
