Abstract: 384,601. Squirting. HYDRAULIK GES., 72, Mulheimerstrasse, Duisburg, and SCHLENSTEDT, O., 64, Hundsbuschstrasse, Speldorf, M³lheim, both in Germany. July 7, 1932, No.,19164. Convention date, July 17, 1931. [Class 83 (iv).] A lead cable press of the type in which the container is movable relatively to the die and mandrel in the direction of extrusion, has an integral frame supporting both the die holder and mandrel holder. Lead is fed through an inlet 5 to the container 2 and is extruded between a die 7 and mandrel 10 by forward movement of a ram 12 and the container 2, actuated from the hollow piston 15 through which the cable passes. The return movement is effected by pistons 19 in cylinders 20. The carriers for the die and mandrel are both supported in the integral frame 1. The container 2 slides on longitudinal keys in the casing, a clearance permitting radial expansion. The mandrel carrier is secured by nuts 11 to permit longitudinal adjustment.

Abstract: 1,150,282. Fuel cells. ENERGY CONVERSION Ltd. 29 April, 1966 [7 May, 1965], No. 19327/65. Heading H1B To maintain the water content of the electrolyte constant the temperature of the cell is controlled in dependence on the relationship between the moisture content in the oxidant exhaust and inlet. As shown, the mass flow of oxidant is regulated in dependence on the cell current by means of a shunt excited solenoid controlled needle valve 20, 11. The back pressure is sensed in outlet chamber 4 and controls a pressure regulator 14 in the oxidant inlet which thereby maintains the back pressure constant. A thermostat 16 sen ses the oxidant outlet temperature and controls a heater 9 in the inlet to maintain the outlet temperature constant. The moisture content of the inlet oxidant is sensed by a sensor 35 and compared in a comparator 32 with the moisture content of the outlet. A temperature controller 29 responding to the comparator 32 controls the temperature of the cell.

Abstract: The invention comprises silanes of the general formula <FORM:1007333/C3/1> wherein R is a monovalent hydrocarbon radical free from aliphatic unsaturation; Z is the group -R12P where R1 is alkyl or aryl and may contain oxygen or sulphur attached to phosphorus; X is halogen; n is 2 or 3 and x=0, 1 or 2.  The silanes may be prepared by (1) Wurtz synthesis using chloroalkyl silanes and chlorophosphines, (2) Arbusor or Michaelio Arbusor reaction and (3) reacting a secondary phosphine R12P-H with a silane containing olefinic unsaturation.  The reaction may be carried out at 0 DEG  C. to the reflux temperature of the reactants in the presence of a free radical catalyst, e.g. azobisisobutyronitrile.  Pentavalent phosphorus atoms are obtained by using secondary phosphine oxides or sulphides or by reaction of tervalent phosphorus containing silane in the presence of HgO or sulphur. Polymers containing pentavalent phosphorus may be obtained by hydrolysis of the corresponding silanes or by treating polymers containing trivalent phosphorus with hydrogen peroxide or sulphur. Hydrolysis of the halosilanes to siloxanes having the general formula <FORM:1007333/C3/2> wherein Z and R are as above and a=0, 1 or 2 is effected by dissolving in benzene or toluene and adding water at 0 DEG  to 15 DEG  C. Siloxane copolymers may also be prepared containing the unit <FORM:1007333/C3/3> wherein A is a monovalent hydrocarbon or substituted hydrocarbon radical and y=0, 1, 2 or 3 by (a) cohydrolysing the corresponding silanes, e.g. cohydrolysis of dimethyl dichlorosilane, methyl (diphenyl phosphinomethyl) dichlorosilane and trimethyl chlorosilane, or (b) catalystic copolymerization of phosphorus containing siloxanes with siloxanes containing the above unit in presence of KOH, e.g. copolymerization of a phenylmethylpolysiloxane with ethyl (diphenylphosphinoethyl) polysiloxane. The polymers and copolymers may be used as lubricants and in the preparation of elastomers and resinous coating materials.

Title: Purification of ethylenically unsaturated monomers
IPC: B01J41/04
Filed: 1963-05-20
Abstract: Polymerization inhibitors, especially hydroquinone, the monomethyl ether of hydroquinone, t-butylcatechol or p-hydroxy phenylamine, are removed from ethylenically unsaturated monomers, styrene, a-methylstyrene, ethyl styrene, vinyl toluene, divinylbenzene, trivinylbenzene or vinyl napthalene, by a process which comprises contacting the inhibitor containing monomer with the salt form of an anion exchange resin having a macroreticular structure and a specific surface area of at least one square metre per gramme when measured by the BET method using nitrogen adsorption at - 195 DEG  C.  The anion exchange resin may be in the sulphate, nitrate, carbonate, bicarbonate or phosphate form, the preferred form being the chloride. It is advantageous to have the anion exchange resin in the anhydrous state, thus if the monomer contains water not only will the inhibitor be removed but the monomer will simultaneously be dehydrated.  The resin may be used in the form of a bed contained within a column, and the resin may be of the quaternary ammonium or tertiary amine type. The Specification refers to a large number of commercially used polymerization inhibitors which are most of the amine or phenol type, and in examples describes the efficiency resulting from the use of a resin having a macroreticular structure compared with the standard so-called porous resin, using ethyl acrylate, methyl methacrylate and styrene monomers.ALSO:Polymerization inhibitors, especially hydroquinone, the monomethyl ether of hydroquinone, t-butylcatechol or p-hydroxy phenylamine, are removed from ethylenically unsaturated monomers, alkyl or aryl acrylates, methacrylates or ethylacrylates, styrene, a-methylstyrene, ethyl styrene, vinyl toluene, vinyl chloride, vinylidene chloride, vinyl stearate, divinylbenzene, trivinylbenzene or vinyl naphthalene, by a process which comprises contacting the inhibitor containing monomer with the salt form of an anion exchange resin having a macroreticular structure and a specific surface area of at least one square metre per gram when measured by the B.E.T. method using nitrogen adsorption at -195 DEG  C.
