Patent GB-1056048-A (GB)
Title: Process for the production of salts of organo-fluorosilicic acids
Inventor: MUELLER RICHARD
IPC: C07F7/12
Filed: 1964-04-20
Abstract: Alkali metal, alkaline earth metal, ammonium, quaternary ammonium and organoammonium salts of mono-organo-fluorosilicic acids are prepared by reacting an organotrifluoro-silane with a salt of hydrofluoric acid. A precursor, e.g. an organo-trihalosilane, may be used in place of the organo-trifluorosilane, fluoridization and complex formation taking place in one step.  Less soluble salts may be obtained from more soluble salts by double decomposition.  Examples of organo-groups are methyl, ethyl, and phenyl.

Filed: 1930-05-28
Abstract: 340,002. Telefunken Ges. f³r Drahtlose Telegraphie. May 29, 1929, [Convention date]. Television.-In polygonal mirrors for television, the surfaces are obtained in correct position by pressing a plastic or fluid mass, either a readily fusible metal or " Bakelite," into a mould. The mass may itself form the mirrors by reason of contact with a highly polished steel mould and subsequent silvering. Alternatively mirrors may be positioned agamst positioning means by pressure of the fusible material into a mould. As shown in Fig. 1, a metallic wheel rim 5 formed with dovetails is centred on an axial shaft in the steel matrix 1 having highly polished interior surfaces 2 lying exactly in the desired mirror places, and the mass is pressed into the space 9 during rapid rotation. In the modification shown in Fig. 2, the dovetailed extension 16 of the carrier plate 15 of tine mirror 14 is inserted into the opening 17 in the wheel rim 5, and the mass is pressed in and forces the mirror 14 against the hardened tips of the adjusting screws 10 set in the rigid ring 1. A Weiller wheel may be manufactured by these methods, preferably by constructing the mirror carriers 15, Fig. 2, in the form of wedges so that the openings 17 may all be parallel to the axis of rotation.

Abstract: 962,287. Magnetic brakes. LANDIS & GYR A.G. May 1, 1962 [May 19, 1961], No. 16678/62. Heading H2A. The brake magnet 1, for an electricity meter, is mounted on the meter frame 5 so that the force required to rotate it, relative to the meter disc 13 by worm and wheel 14, 8, is independent of the force used to secure it to the frame. Setscrews 3, held in wheel 8, are used to set the magnet at the correct height and rotate with it over the limited arc required. Screw 2, which has a shoulder portion 7 to bear on wheel 8, screws into the magnet body to hold it on to the set-screws 3. The head of screw 2 engages a resilient spring 4 which bears against the meter frame so that only a constant frictional load, between members 4, 8 and frame 5, must be overcome when the magnet is rotated. By means of shims placed either under the head of screw 2 or against the face of shoulder 7 each force can be independently varied.

Title: Improvements in or relating to the plasticizing of fabrics and the production of laminated fabrics therefrom
IPC: D06M17/02
Filed: 1944-09-04
Abstract: A fabric comprising thermoplastic fibres of an organic derivative of cellulose and non-thermoplastic fibres is treated with an aqueous dispersion of triethyl citrate so as to plasticise the thermoplastic fibres.  Fabrics containing continuous filaments or staple fibres may be treated.  The triethyl citrate is absorbed preferentially by the cellulose derivative thermoplastic fibres with but little deposition in or upon the non-thermoplastic fibres.  The treated fabric may be used as a laminating fabric in the production of compound fabrics, the bonding operation being facilitated by the presence of the triethyl citrate in the thermoplastic fibres.  The aqueous dispersion of the plasticiser may be prepared with the aid of an emulsifying agent such as a long carbon-chain alkyl sulphate.  The emulsifying agent may contain 12-16 carbon atoms in the alkyl group, and it is preferably used in the form of its sodium salt.  It may be compounded with mineral oil.  The impregnated fabric is dried and it may be used directly for the production of laminated fabric or may be aged so as to allow migration of plasticizer from the non-thermoplastic to the thermoplastic fibres.  The fabric may be given a short heat treatment at 120-150 DEG  C. after ageing so as to remove any tackiness.  The cellulose derivative fibres may be of cellulose acetate, propionate, butyrate, or other cellulose ester or of ethyl, benzyl, or other cellulose ether.  The non-thermoplastic fibres may be cotton, linen, or regenerated cellulose fibres.  An assembly of superimposed fabrics containing one or more layers of the plasticised fabric may be wetted with water or steam or with a liquid or vapour which has a solvent or swelling action, and then subjected to heat and pressure, or the assembly may be bonded together by dry heat and pressure. Specification 549,050 is referred to.
