Title: Improvements in or relating to a silicone rubber gum composition
IPC: C08K5/46
Filed: 1955-01-25
Abstract: Silicone rubbers incorporating as fillers silica having surface-bonded alkoxy groups, are given improved heat resisting properties by incorporating a few per cent by weight of an antioxidant.  Specified classes of antioxidants are secondary aryl amines, diarylalkylene diamines, diarylarylene diamines, aromatic ethers, monoor polynuclear phenols, polyhydroxy phenols, alkyl or aryl substituted hydroquinones and chlorinated aromatic polynuclear hydrocarbons.  Examples are given of dimethyl silicone rubber containing from 33-56 parts hydrophobic silica having surface-bonded alkoxy groups, and from 2-10 parts of antioxidant, per 100 parts silicone gum.  Comparative figures for these rubbers and rubbers without antioxidant of various physical qualities before and after ageing at various temperatures up to 450 DEG  F. are given.  The antioxidants used in the examples are diphenylamine, hydroquinoneiminobenzyl - ether, hexachloronaphthalene, 2-6 ditertiarybutyl 4-methylphenol, para - di - (isopropoxyphenyl) amine, ditertiaryamylhydroquinone, ditertiarybutylhydroquinone, hydroquinone dibenzylether, hydroquinone iminomethyl ether and hydroquinone dimethylether.  The antioxidant may be incorporated in the moulding composition or moulded articles may be impregnated between the press cure and the after cure with a solution of the antioxidant in e.g. a mixture of benzene and acetone, which swells the rubber.  The compositions may include benzoyl peroxide as curing catalyst. Specification 762,180 and U.S.A. Specification 2,657,149 are referred to.

Abstract: 808,244. Perforating-apparatus. CRAMBON Ltd. Jan. 30, 1957 [Jan. 30, 1956], No. 3310/57. Class 31 (2). Apparatus for forming perforations in sheet material comprises a blade having a rectilinear edge and mounted for rotation about an axis lying in a plane parallel to the said edge, and a non-rotatable blade having a rectilinear edge and mounted with the said edge skew with respect to the other axis but lying in a plane parallel to the said axis, one of the blades having an interrupted edge and the other blade being a counter-blade having a continuous edge, and the blades being mounted so that upon rotation of the rotatable blade, they co-operate to exert a progressive shearing action along their length upon sheet material fed between the blades. As shown, a blade 11 having an interrupted edge is secured to a rotatably-mounted cylinder 10 and co-operates with a counter-blade 20 which has a continuous edge and is carried by a pivotallymounted lever 21 the free end of which is held against an adjustable stop 23 by means of a spring 22. The blade 11 is mounted so that its edge is skew with respect to the axis of the cylinder 10, and the blade 20 is mounted so that the edges of the blades 11, 20 are two distinct generatrices of the surface generated by the edge of the blade 11 during its rotation. An adjusting device 14 mounted in advance of the cylinder 10 enables the rows of perforations formed by the apparatus to be correctly located with respect to tensioning rollers 15, 16. Circular knives 17, 18 may be mounted after the cylinder 10 to divide the perforated web lengthwise. The means for feeding the web of material are coupled to the means for rotating the blade 11 in such a way that the rows of perforations extend perpendicularly to the direction of feed of the web. To vary the distance between adjacent rows of perforations, the means for rotating the blade 11 may incorporate transmission means comprising a system of elliptical gears.

Abstract: A concentrated beer which can be transformed directly into a drinkable form by dilution is prepared by alcoholic fermentation of an over-concentrated, preferably also overhopped, beer wort. A further concentration of the beer may be obtained by freezing out water, and, if desired a fractional distillation, the distillate up to the water fraction, or up to the water and alcohol fraction, being returned to the still.  The alcohol content may be increased or reduced.  The strongly brewed and over-hopped beer may be mixed after the main fermentation with a large addition of concentrated malt extract and the after fermentation allowed to take place in the storage vessel.
