Title: Tetrafluoroethylene/hexafluoropropylene copolymer dispersions
IPC: C09D179/08
Filed: 1965-11-02
Abstract: A stable, substantially anhydrous dispersion of 95/5 to 5/95 (weight ratio) tetrafluoroethylene/hexafluoropropylene copolymer particles in an organic liquid, which forms a water/organic liquid azeotrope and which does not physically or chemically interfere with the polymer dispersion, said copolymer particles having an average radius of from 0.01 to 3 microns, no particles having radii larger than 3 microns, is obtained by slowly adding an aqueous dispersion of the particulate tetrafluoroethylene/hexafluoropropylene copolymer to a boiling organic liquid in a vessel and continuously withdrawing the vapours of the resulting water/organic liquid azeotrope, separating the organic liquid from the azeotrope and returning it to the vessel, until the organic liquid in the vessel is substantially anhydrous and then (c) comminuting the resulting material.  The dispersion may also contain additional film-forming components, e.g. alkyd resins, epoxide resins, acrylic polymers, nitrocellulose, phenolformaldehyde resin, aminoplast resin or a polyurethane. Thermosetting films can be obtained by adding to the dispersion a precursor for a thermally stable polymeric material or a thermally stable polymeric material having a decomposition point above that of the copolymer, e.g. a polyimide precursor, poly-(m-phenylene diamine isophthalamide), a polyoxadiazole or polyvinylidene fluoride. Polyimide precursors exemplified are a polyamide acid solution made by reacting benzophenone tetracarboxylic dianhydride and p,p1-methylene dianiline and a polyamide acid ester made by reacting dibutyl ester of benzophenone tetracarboxylic acid and methylene dianiline.  Organic liquids used are toluene and methyl isobutyl ketone.ALSO:Metals e.g. steel and aluminium are coated with a composition comprising (a) a particulate tetrafluoroethylene / hexafluoropropylene copolymer and (b) a film-forming component dispersed in an organic liquid (see Division C3).  Thermosetting coating compositions may be obtained if (b) is a precursor for a thermally stable polymeric material or a thermally stable polymeric material having a decomposition point above that of (a). Film forming components may be alkyd resins, epoxide resins, acrylic polymers, nitrocellulose, phenol-formaldehyde resin, ammoplast resin or a polyurethane.  Thermosetting compositions are obtained when (b) is a polyimide precursor, poly (m-phenylenediamine isphthalamide) or polyvinylidene fluoride. The compositions may be applied by brushing, spraying or doctor blading. The compositions are useful in coating wire, metal foil, cooking utensils, boilers, pipes, ship bottoms, ice-cube trays, industrial containers, moulds, and as binding agents in the preparation of coated glass fabrics.

Abstract: 1277309 Moulding reinforced concrete posts O L REED 22 Sept 1969 46624/69 Heading B5A [Also in Division El] Apparatus for forming reinforced concrete posts comprises an elongated hollow mould 20 having a closed end 21 and an open end and a plurality of elongated side walls. An elongated feed conduit 13 extends from a hopper 15 along the centre of the mould cavity to closed end 21 and the mould is mounted on wheels 22 for longitudinal movement relative to the conduit 13. A flexible tubular air impermeable liner 44 with one closed and one open end and substantially the same cross-section as the mould cavity is located inside the mould and surrounds the conduit 13. A set of elongated tubes 39 for carrying reinforcing rods 40 are fixed to the conduit and the open end of the mould can be closed by doors 35, 36 operable by pistons and cylinders 37, 38. One side wall of the mould 55 is hinged at 56 and held in position by latch 57 and the opposite wall 48 may be moved into the mould cavity to expel the moulded post. In operation the mould and conduit are initially separate and reinforcing rods 40 are placed into tubes 39 with the ends of the rods facing radially inwards. A flexible liner is pulled over the conduit and reinforcing rods and the mould is moved over the conduit. Fluid concrete from hopper 15 is supplied to the conduit by plunger 17 and emerges from the conduit to fill the space occupied by liner 44, air escaping through openings 45 in the liner and corresponding holes in the mould wall. As the liner fills, the reinforcing elements become embedded in the concrete and are pulled out of tubes 39 as the mould is forced to the right against the action of counterweight 28 by the build up of concrete. When the mould reaches its final position, with its open end level with the end of the conduit, doors 35, 36 are closed and concrete is forced in until the mould is completely filled. Latches 57 are then unlocked by cylinders 58 and mould wall 48 is moved to the right pivoting the opposite wall 55 to its open position and ejecting the moulded article.

Abstract: 1300480 Luminescent screens LICENTIA PATENT - VERWALTUNGS - GmbH 15 Oct 1970 [16 Oct 1969 29 April 1970] 49109/70 Heading H1D In the manufacture of a multi-dot colour television screen by irradiating a sensitive layer through a shadow mask by means of electrons, the dots are made smaller than the corresponding apertures in the shadow mask by applying an electric field between the screen and the shadow mask during the irradiation step. This step may be part of the process of forming the phosphor dots themselves; alternatively it may be part of the process of forming an opaque layer with apertures in which the phosphor dots may be deposited by known methods, the effective size of the dots in this case being determinized by the size of the apertures in the opaque layer. The electric field causes the electrons exposing the dots near the edges of the screen to be displaced towards the centre. This can be corrected by a suitable magnetic field or by moving the centre of deflection forwards, e.g. by moving the deflection coils. Alternatively the shadow mask may be displaced towards the electron gun, and if the mask is supported by bimetallic elements for temperature-compensation purposes such displacement may be effected by cooling the bimetallic elements. Instead of correcting the positions of the dots in these ways the completed tube may be operated with an electric field between the mask and the screen.
