Title: Improvements relating to organopolysiloxanes
IPC: C08G77/00
Filed: 1955-12-05
Abstract: High surface area aluminas specified for use as fillers in making silicone rubber are: (1) hydrated aluminium oxide (34.7 per cent combined water and 64.4 per cent Al2O3, chemically aluminium trihydrate); (2) activated aluminium oxide obtained by heating (1) for 64 hours at 480 DEG  F. to remove 28 per cent of the combined water; (3) activated alumina obtained by heating (1) to remove all the combined water; (4) alpha alumina; and (5) gamma alumina made by (a) vaporizing AlCl3 by heating it with natural gas, the water formed by the combustion of the gas hydrolysing the chloride vapour to the hydroxide, which at 500 DEG  F. is dehydrated and converted to a fine particle size (20 to 40 millimicrons) gamma alumina, which is then collected and freed of HCl; or (b) hydrolysing AlCl3 vapour at 500 DEG  F. with high temperature steam.  Gamma alumina having a hazy X-ray gamma structure is stated to undergo a change to a sharp gamma structure as the temperature is raised to about 900 DEG  C. where a transition to a sharp alpha pattern takes place (see also Ind. and Eng. Chem., p. 158, Feb. 1945).ALSO:A composition in particulate form and convertible to the solid elastic state is made by polymerizing a completely condensed cyclic organopolysiloxane in the presence of a solid filler and a ferric chloride bromide or iodide catalyst.  The siloxanes used are completely condensed diorganocyclic polymers containing at least 50 mol. per cent of Si-bonded methyl radicals, other radicals, if any, being other alkyl, aryl, aralkyl, alkaryl, haloaryl, or cycloalkyl, and preferably contain 3 to 12 Si atoms per molecule.  Fillers specified are silica xerogel, silica aerogel, fumed silica, titania, calcium silicate, chromic oxide, cadmium sulphide, a  and g -alumina (see Group III), asbestos, glass fibres, calcium carbonate, carbon black, lithopone, talc, diatomaceous earth and hydrophobic silicas, the fillers preferably having a surface area from 1 to 900 sq. metres per gram.  The polymerization is preferably effected at 100 DEG  to 200 DEG  C. in 3 to 100 hours, using from 0.1 to 1 part of the filler per part of siloxane and the catalyst in amount of 0.01 to 5 per cent by weight of the siloxane.  In examples, octamethylcyclotetra-siloxane was polymerized in the presence of ferric chloride and (1 to 5) silica aerogel; (6) diatomaceous earth or alumina.  The products were either mixed with benzoyl peroxide or with a methylsiloxane gum and benzoyl peroxide, and heat cured. Curing can also be effected by heating with t-butyl perbenzoate or by high energy electron irradiation without curing agents.  The compositions may be dissolved in solvents, e.g. toluene, xylene and butanol, and be used for coating and impregnating purposes, or after milling they may be used in conventional extrusion, moulding and calendering applications. Specifications 594,481, [Group IV], 594,730, [Group III], 735,807 and 760,599 are referred to.

Abstract: 307,822. Butterworth, F., and Horsburgh, R. W. March 14, 1928, [Convention date]. Thickness of paper, regulating and gauging; pulp, regulating flow and consistency of.-Light sensitive cells or mechanical or electromechanical means are used to detect the changes in the thickness of paper during its manufacture in the paper machine and with or without amplifiers or relays the means are used to adjust, automatically either the speed of the machine or the valve of the stuff chest to maintain the correct thickness or weight of paper. In the apparatus illustrated, the paper web P, Fig. 2, during manufacture passes beneath a source of light 23 backed by a reflector 26 and the light passing through the paper is focused by lenses 28, 29 on to a cell sensitive to light rays such as a selenium or photo-electric cell 31, which, with a galvanometer 33, Fig. 1, and transformer 34 is in the circuit of a battery 32. An amplifier 35 comprises a fixed solenoid 41, Fig. 3, and a core 43 carrying a roller or slide 44 insulated therefrom. This roller normally rests between two contacts 48, 49 on a block 50. Variation in the thickness or weight of the paper during manufacture moves the core 43, and the roller 44 makes contact with one or other of the contacts 48, 49 thus completing the circuit of the motor 55 which, through gearing 58 moves a contact 60 over studs 61 of a rheostat in the shunt circuit of a motor 9 and adjusts the speed of the paper machine driven thereby. The motor 55, through gearing 56 also rotates a screw 51 and thus slides along the block 50 until the roller 44 is in the mid position between the contacts 48, 49, thus stopping the relay, leaving the rheostat adjusted to the new position. Instead of the fixed coil 41, a moving coil may be used and the motion of the coil may operate a dependent arm immersed in a liquid resistance in the circuit of the motor driving the paper machine. The motor 55 may be used to rotate the brushes of a variable speed alternating current motor which may be used in place of the motor 9. The relay may be used to operate an auxiliary stuff cock by which pulp is supplied to the paper machine. Where steam or internal combustion engines are used as prime movers, the motor 55 may be used to control steam or gas valves, governors &c.

In the embodiment described two reading devices 4, 5 are provided for receiving the token 7 and a credit-card 11 respectively. The token 7, Fig. 4, has an apertured plate 26 which co-operates with switch - actuating feelers located in a push-in socket 6 of the reading device 4. The token includes a digital counter visible through a window 25 and coupled with a shaft 9 connected to quantity or price recording device of the appliance 1. The identification data read from token 7 and card 11 are compared in a control unit 13 with identification data stored in store 17 and if a suitable correspondence is found the appliance 1 is actuated. A solenoid 52 is then energized through lead 8 to rotate pawl 49 and lock the token in position until dispensation has ceased. The quantity and/or price of the petrol dispensed and the identification data of the customer is recorded in a recorder 18 for subsequent computation of the customer's account. The counter, which is provided with means to prevent reverse rotation except by a special key, serves as a check for the customer on the amount dispensed to him between computations of the account. The counter may also be arranged (see Figs. 5, 6, not shown) so that preset counting values levers (61) are allowed to pivot under the action of springs (59) and displace one of the feelers to modify the data read by the reading device 4. This alters the correspondence between the read and stored data and ceases dispensation thus limiting the amount available to the customer.
