Abstract: An organopolysiloxane elastomer composition for making glass cloth laminates comprises an organopolysiloxane capable of being cured and having 1,98-2,05 organo groups per silicon atom and of molecular weight 1 X 105-10 X 105, preferably 3 X 105-7 X 105, together with up to 10% of a linear organo polysiloxane having 1,02-1,50 organo groups (preferably methyl groups) per silicon atom and of molecular weight not more than 4,000 preferably 1,000-3,000.  The organo groups of the organopolysiloxane may be methyl, ethyl, phenyl, tolyl, vinyl or alkyl, but are preferably methyl groups with a minor proportion of vinyl groups.  The organopolysiloxane composition may comprise fillers, such as finely divided silica, diatomaceous earth, finely divided alumina, titanium dioxide or calcium carbonate and such fillers may be coated with low molecular weight organopolysiloxane such as octomethylcyclotetrasiloxane or structure control materials such as (tetramethylethylenedioxy)-dimethylsilane or -diphenylsilane may be added to the composition.  Curing agents such as benzoyl peroxide, dicumyl peroxide, di-tert-butyl peroxide, 2:4-dichlorobenzoyl peroxide and tert-butyl diperphthalate may be included.  A curing agent activated at a low temperature, e.g. 2:4-dichlorobenzoyl peroxide, may be used with one activated at a high temperature, e.g. dicumyl peroxide, and the laminae given a preliminary curing above the lower temperature to render them more handleable.  Specification 806,563 is referred to.

Title: A reservoir pen with a retractable ball
IPC: B43K24/08
Filed: 1956-06-28
Abstract: 797,032. Reservoir pens. GOSSIAUX, W. June 28, 1956 [June 28, 1955], No. 19990/56. Class 146(3) A retractable ball-point pen comprises a pair of cams 11, 12 which define the limits of movement of an intermediate part 8 which is movable longitudinally with an ink reservoir, the intermediate part having two cam faces 9 and 10, a push button or sliding weight for causing longitudinal movement of the reservoir 2 against a spring 4, the cams 11, 12 being so arranged that longitudinal downward pressure on the reservoir disengages the teeth of the upper cam 10 of the intermediate part 8 from the teeth of the upper cam 12 and the teeth of the lower cam 9 of the intermediate part engage the teeth of the cam 11 to cause rotation of the reservoir, release of such pressure permitting the spring to move the reservoir into either a retracted or extended position. As shown, the cam surface 12, Fig. 4, comprises four teeth, two being large teeth 30 having sloping surfaces 22 and vertical faces 23. and two small teeth 24 having sloping faces 25 and vertical faces 26, thus providing deep hollows 27 and shallow hollows 28. The cam 10 comprises two teeth 19 having sloping faces 20 and vertical faces 21. The cam 9 has four teeth 13 provided with vertical faces 15 and sloping faces 14. The cam 11 comprises teeth 16 provided with sloping faces 17 and vertical faces 18. In operation, the press button 6, Fig. 1, is depressed thus disengaging the teeth 19, Fig. 4, from a hollow 27 or 28 and causing the teeth 13 to engage the teeth 16 thus rotating the part 8 a fraction of a turn. As a result, a tooth 16 which previously engaged a deep hollow 27 is positioned in alignment with a shallow hollow 28 or vice versa. Thus on release of the button 6, the part 8 and reservoir 2 are pressed rearwardly by the spring 4, into either a retracted position in which the ball point 3 is within the barrel 1 or an advanced position in which the ball point 3 projects beyond the barrel 1. In a modification, not shown, the push button may be replaced by a weight slidable in the cap 7.

Title: Improvements in and relating to the production of substituted phenols
Inventor: KUNZ WERNER
Filed: 1950-08-11
Abstract: Ortho-alkyl phenols are prepared by introducing an olefine into a slurry containing phenol (C6H5OH) and an acidic alkylation catalyst, the temperature being maintained at a value such that the reaction mixture remains in the form of a slurry which can just be stirred throughout the alkylation.  Preferably the temperature is in the range -10 DEG C. to + 10 DEG C. and is decreased as the reaction proceeds.  Preferred alkylation catalysts are sulphuric acid, phenol sulphonic acid, oleum or mixtures of sulphuric acid with acetic acid, phosphoric acid or boron trifluoride.  In an example phenol is alkylated with isobutene in the presence of sulphuric acid to give a product containing 22 per cent. by weight of ortho-tertiary butyl phenol and 65 per cent. of 2:4-di-tertiary butyl phenol.

Title: Improvements in and method of making insulating pads
IPC: C04B30/02
Filed: 1945-08-08
Abstract: 623,634. Compound sheet materials. DEHN, F. B. (Consolidated Vultee Aircraft Corporation). Aug. 8, 1945, No. 20345. [Class 140] An insulating pad such as that described and claimed in Specification 623,633, is made by applying a film of a rubber hydrohalide on to a matted layer of fibreglass, after treating the film or the surface of the padding with a solvent which renders the film adhesive and applying heat and pressure to bond the film to the matted layer and securing a finishing fabric to the other face of the layer. As shown in Fig. 3, a web 8a of loosely-matted fibreglass is fed by rolls 13 and 14 while the film 9a drawn from roll 15 and over rolls 16 and 17 is sprayed with a solvent, e.g. methyl ethyl ketone, from sprayplate 18. The film and matted layer then pass together through the feed rolls of which the rolls 13 are internally heated to accelerate the adhesion and evaporate the solvent. The combined web is cut into the desired sections and covered on the bare face with a textile fabric which is folded around the edges of the combined film and fibreglass and secured thereto by seams extending throughout the marginal portion, film, fibreglass and the covering face. In a modification (Fig. 4), the top face of the matted layer 8a is moistened with the solvent from spray-plate 18a and the layer meets the film 9a at the feed rolls 24-25. They then pass over a pad 29 connected by the pipe 30 to a vacuum pump provided with a perforated top plate 31 through which air is drawn, causing the film to unite with the fibreglass. To seal off the film with the vacuum pad, the film overlaps the side edges of the matted web. Infra-red lamps 33 accelerate the adhesion and dry the combined layers. Specification 451,573 also is referred to.

Title: Improvements in safety devices for aeroplanes
IPC: G01P1/10
Filed: 1928-07-13
Abstract: 318,707. Wynn, E. D. July 13, 1928. Air-current indicators.-A device for use on aircraft to sound an alarm while the air speed is below a given value comprises a siren consisting of two drum-like members rotating relatively to each other and having orifices through which air passes to produce a warning note, the device including a member acted on by the air pressure and having its movement opposed by a spring, so that when the given air speed is attained the said member is moved against the resistance of the spring and the warning note is cut off. In one form, I'ig. 1, the siren comprises a rotating member,a, driven by a fan &c. not shown, and provided with air-holes a<2>, and a stator b with holes c. Around the stator is a drum e having holes f normally registering with the holes c, and provided with vanes j so that the air pressure tends to rotate it against the restraint of a spring g. When the air speed reaches the desired value the drum is turned through a sufficient angle to cause the holes c to be covered and the siren ceases to sound. In another form, Fig. 2, the siren comprises a member a as above and a member b with vanes b<1> by which it is rotated in the opposite direction to the member a. The pressure of the air on the member a tends to move it axially against the restraint of a spring g, and when the air speed is sufficient the two members come into contact at b<2> and friction then causes them to revolve together at the same speed so that the siren ceases to sound. The spring is mounted between rollers k, l of which the latter is revolubly mounted on a quick-pitch thread on the boss a<3> and has a peg &c. m adapted to engage a peg &c. n on the boss. With this arrangement the tension of the spring is made greater when the rotor turns in one direction than when it turns in the opposite direction so as to avoid any difference between the respective speeds at which the siren is brought into action and is cut off.
