Title: Improved organopolysiloxane rubbers
Filed: 1955-11-01
Abstract: A curable composition comprises an organopolysiloxane convertible to the cured, solid, elastic state and a filler consisting essentially of a solid, finely divided alkyl polysiloxane obtained by effecting hydrolysis of an alkyltrihalogenosilane in a water-in-oil emulsion, and thereafter isolating the siloxane so formed.  The filler may be used in amount of 10 to 100 per cent by weight of the filler and convertible siloxane.  Other fillers, e.g. titania, lithopone, silica aerogel, iron oxide and calcium carbonate may be added in amount not exceeding 10 per cent by weight of the siloxane filler, and also the customary additives.  The compositions may be cured, e.g. by heating with curing agents such as benzoyl peroxide, t-butylperbenzoate and zirconyl nitrate or by means of high energy electrons.  In making the siloxane filler a water-in-oil emulsion is first made by mixing with water a hydrocarbon oil (e.g. mineral oil, paraffin oil or albolene) preferably having a viscosity of 25 to 3000 c.p.s. at 25 DEG  C., and an emulsifying agent, the water being used in a weight ratio of 0.1 to 1 part per part of oil. The silane, e.g. methyl-, ethyl- or butyl-trichlorosilane, preferably as a 10 to 50 per cent solution in an inert solution, e.g. iso-octane, and in amount such that there is from 0.25 to 4 parts of water per part of silane, is added thereto with vigorous stirring.  The gel thus formed is allowed to settle and then isolated with subsequent washing, drying and heating until constant weight is attained.  The resulting product is a fluffy finely divided siloxane having a surface area of 75 to 350 square metres per gram.  Examples (1) and (3) refer to the siloxane filler made in the above manner and examples (2) and (4) refer to elastomer-forming compositions containing the siloxane filler. Uses-as insulation for electrical conductors and as gaskets, tubing or shock absorbers.  Specifications 738,419, 757,024 and 788,879 are referred to.

Title: Improvements in fluid control valve testing arrangements
IPC: F16K37/00
Filed: 1939-12-06
Abstract: 533,866. Valves. BRITISH THOMSONHOUSTON CO., Ltd. (General Electric Co.). Dec. 6, 1939, No. 31615. [Class 135] A testing arrangement for a fluid control valve 13, having operating means consisting of a fluid operated servomotor with a piston 17 connected to the valve stem 14, comprises a valve controlled byepass 41, 42, connected to the servomotor on opposite sides of the piston 17, to check the movability of the stem 14, the byepass being automatically rendered ineffective in response to a limited movement of the valve stem. The piston 17 is biassed to the valve closing position by a spring 19 and is moved to the valve opening position by fluid pressure led to the cylinder 18 by pipes 20, 25, including a valve 21. Piston valves 38, 39. on a common stem are normally positioned as shown so that the pipe 42 is blocked and the pipe 41 is open at 36 to the atmosphere. To test the operability of the valve 13 a hand-lever 45 is raised to close the duct 36 and connect the pipes 41, 42. The pressure on opposite sides of the servomotor piston 17 is thus equalized and the latter moves in a direction to close the valve 13. Such valve-closing movement is very limited and ceases as soon as the servomotor piston 17 covers the end of the pipe 42. Upon release of the lever 45 the valve 13 is moved to the fully open position. As shown, the valve 21 embodies a trip latch 27 co-operating with the shaft 30 of a turbine or other part of the mechanism embodying the fluid control valve. Upon excessive speed of the shaft 30 the latch 27 is tripped and the valve 21 moves to exhaust the servomotor cylinder 18, whereupon the valve 13 closes. Means to indicate that the valve 13 is making testing movements consists of contacts 50 electrically associated with a lamp 48. Upon slight testing movements of the valve 13 a projection 51 on the valve stem 14 closes the contacts 50 and the lamp 48 is illuminated.

Title: Improvements in or relating to valve discs, gaskets, and similar articles
IPC: F16K1/36
Filed: 1929-10-18
Abstract: Valve discs, gaskets, and similar articles, are moulded from a composition consisting of asbestos in a spun or woven condition impregnated with a potentially reactive resinoid, for example, a phenolic resinoid or cresol-formaldehyde.  The asbestos material is preferably first impregnated with the binder and then subjected to preliminary heating, for example to 85 DEG  C., to eliminate the solvent.  For valve discs, superposed blanks of this material are then subjected to a pressure of 5000 to 9000 lbs. per square inch in a cold state in a mould which is subsequently heated to 125 DEG  to 160 DEG  C. to convert the resinoid to an insoluble and infusible form.  There is preferably about 25 to 45 per cent by weight of resinoid in the finished articles.  The resinoid may, moreover, be applied wholly or in part in a pulverized form.  In place of the woven asbestos there may be substituted, particularly for the inner portions of the articles, a mass of loose thread ends obtained by shearing the woven fabric after impregnation.  A lubricant, such as butyl stearate, may be incorporated in the resinoid binder to facilitate the discharges of the articles, whilst hot, from the mould.
