Title: Polymerisation process
IPC: C08F2/50
Filed: 1965-05-19
Abstract: Monomeric materials are polymerized by contacting them with an initiator complex which is formed by contacting a linear or cyclic ether base having an active hydrogen atom in the molecule with an unsaturated compound containing a carboxylic anhydride structure, a carbonyl group of which is conjugated with an ethylenic double bond or conjugated system of double bonds present in the unsaturated compound, and initiating the reaction by irradiation. The monomeric material is preferably one which does not readily copolymerize with anhydrides especially acrylates and methacrylates.  The preferred ethers are ones having no substituents on the a -carbon atoms, particularly tetrahydrofuran. Other suitable ethers are diethylene glycol, poly(ethylene glycol), 1,3-dioxolan, 1,4-dioxan and bis-(2-methoxy ethyl ether).  Suitable anhydrides are maleic anhydride and ones having at least one electron-withdrawing group on the ethylenically unsaturated carbon atoms, e.g. monochloromaleic and dichloromaleic anhydride. Preferably the ether acts as a solvent and the reaction is carried out in a liquid state. A photosensitizer may be added to the reactants, e.g. benzophenone, anthraquinone or substituted anthraquinones.

Filed: 1977-04-06
Abstract: 1527288 Satellite communication MARCONI CO Ltd 6 April 1976 [22 May 1976] 21293/76 Heading H4C In a satellite communication system wherein (to enable flexibility in carrier choice), prior to amplifying signals to be transmitted, they are subjected to group delay equalization, the signals are additionally subjected to variable gain compression. Disclosed analysis shows that a compression factor can be chosen to reduce coupled distortion in the system, coupled distortion occurring when, due to a.m. having been introduced by the equalization, the a.m. is converted to phase modulation in amplifiers 3 and 6, leading to intermodulation products of the modulation signal. The amount of compression required is discussed in relation to Figs. 3-6 (not shown). The equalization provided at the transmitter compensates the group delay introduced at the satellite, due to non-linearity in filters 5, 7, i.e. a predistortion is provided.

Filed: 1967-05-10
Abstract: 1,151,148. Automatic temperature control. TEXAS INSTRUMENTS Inc. May 10, 1967 [May 10, 1966], No.21648/67. Heading G3R. A system for automatically controlling the temperature of a zone 15 comprises an electric heater 13 in the zone, the current to the heater being regulated by a semi-conductor switching device such as a thyristor Q1 which is controlled according to the zone temperature by way of a thermistor TH1 responsive thereto. Gating signals for the thyristor Q1 are derived by way of a voltage divider R1, D1, R2, TH2 and a winding 21 of a saturable reactor 23, the signals being derived only in the half cycles in which the diode D1 is forwardly biased and after the core 25 of the reactor 23 has been driven to saturation. The reactor 23 is provided with a reset winding 27 energized from a bridge circuit TH1, R4-R7 during the half-cycles in which the thyristor Q1 is not conductive, the amount of reset being determined by the amount of unbalance of the bridge which is in turn a function of the temperature in the zone 15. The position to which the core 25 of the reactor has been set in one half-cycle determines the firing point of the thyristor Q1 in the succeeding half-cycle thereby controlling the flow of current in the heater 13 and hence the temperature of the zone 15. The thermistor TH2 provides ambient temperature compensation. Alternatively the system may be used to control the cooling of the zone 15 by using a thermo-electric cooling device in place of the heater 13.
