Title: Ethylene-vinyl acetate copolymer prepared in the presence of minor amounts of butyraldehyde
IPC: C08F10/00
Filed: 1969-02-19
Abstract: Non-gelling, soluble copolymers of ethylene and vinyl acetate having an ethylene content of 30 to 80 mol. per cent are prepared by polymerizing the monomers in aqueous dispersion in the presence of a free radical forming agent, a protective colloid and an emulsifier and in the presence of an aliphatic aldehyde containing 4 to 8 carbon atoms. The copolymer may contain at least one other polymerizable monomer in an amount of up to 10 mol. per cent of the vinyl acetate exemplified by straight-chain and branched vinyl esters, e.g. vinyl propionate, butyrate or laurate, and the vinyl esters of isononanoic acid, isodecanoic acid or a commercially available blend of branched carboxylic acids containing 9 to 11, 13 to 15 or 17 to 19 carbon atoms, and unsaturated mono- and dicarboxylic acids, e.g. acrylic, methacrylic, maleic and fumaric acids, and esters of the acids with mono- and poly-hydric alcohols. The aldehyde, which is exemplified by butyraldehyde, pentylaldehyde, hexylaldehyde, isobutyraldehyde, 2-ethyl hexylaldehyde and diethyl acetaldehyde, amounts to 0À2-3% by weight calculated on the vinyl acetate and may be added gradually during the course of the polymerization. The free radical forming agent preferably forms part of a redox catalyst system comprising an inorganic or organic per-compound, hydrogen and a colloidally distributed noble metal of Group VIII of the Periodic Table. The catalyst may also include ions of iron, copper, nickel, cobalt, chromium, molybdenum, vanadium or cerium. Transparent or opaque tarpaulin or tent material may be obtained by applying to fabrics filler-containing solutions of the copolymers, e.g. in esters, ketones, chlorinated hydrocarbons or aromatic compounds, and after evaporation of the solvent cross-linking the copolymer by the addition of a peroxide. The copolymers may be combined with other condensation and addition polymers including alkylphenol resins, terpenephenol resins, coumarone - indene resins and aldehyde - ketone resins, colophony and pentaerythritol esters of abietic acids, to produce contact and pressuresensitive adhesives. Example 8 is directed to the copolymerization of ethylene and vinyl acetate in aqueous dispersion in the presence of ammonium persulphate, hydrogen, palladium in colloidal solution, methanol, methyl cellulose, alkyl benzenesulphonate and butyraldehyde. The copolymer and a modified phenol resin having an acid number of 100 and a melting range of 140-160 C. were dissolved in a solvent mixture comprising ethyl acetate, toluene and petrol to give a contact adhesive. A copolymer of ethylene, vinyl acetate and fumaric acid gave a clear solution, free from gelling, in ethyl acetate, toluene and trichloroethylene, and could be cross-linked by the addition of polyfunctional alcohols, epoxides or isocyanates. Comparative experiments disclose the use of acetaldehyde and propionaldehyde in the preparation of the copolymer.

Title: Method of transfer of switching order information for transmission of PCM words
IPC: H04Q11/04
Filed: 1973-02-07
Abstract: A PCM exchange comprises a space stage between a first and a second time stage, and has switching order memories for the control of time and space interchanges arranged in time substages each including a substage in the first time stage and a substage in the second time stage. Upon the connection and the disconnection of a communication path through the exchange, the respective switching order memories must be loaded with switching order information stored in a switching order unit. In order to reduce in a great extent a supplementary communication system between the switching order unit and the decentralized switching order memories, the switching order information is transferred via the space stage to the respective time substages via the same files on which the regular PCM words are transferred. The switching order information is transferred during unchangeably predetermined time slots which are not used for the transmission of PCM words.

Title: Sampled data servo positioning system and sector disk file employing same.
IPC: G05B7/02
Filed: 1979-09-24
Abstract: A sampled data servo positioning system employs an actuator to move a member between a current and a target position. Incremental position feedback is provided only at sampling times. The system employs a model responsive to a velocity related input signal to produce a continually available model incremental position signal. Phase comparing means indicates phase differences between the model and sampled position signals at the sampling times. The system has two operational configurations in the first of which a source of saturation control signals is connected to the actuator to cause maximum acceleration or deceleration thereof. In this first configuration, the model is forced to track the actuator motion by means of feedforward plus feedback control. The feedforward signal represents actuator performance while the feedback signal is the position signal phase difference. In the second operational configuration, a velocity profile signal is applied to the model and the actuator is forced to track the model by means of feedforward plus feedback control. The feedback signal is again the position signal phase difference but the feedforward signal is a predetermined signal representing the desired actuator current to execute the velocity profile. The sampled data servo positioning system may be the access motion control system of a sector servo disk file.
