Title: Process for the adhesion of coatings made of photoresistant polymers to surfaces of inorganic oxides
IPC: C09J11/00
Filed: 1973-07-30
Abstract: 1440979 Coated products RHONEPOULENC SA 30 July 1973 [31 July 1972 7 May 1973] 36245/73 Heading B2E A layer of inorganic oxide is treated with an organosilicon compound having siliconnitrogen bonds which is (a) an aminosilane of the formula or a polysilazane, with the exception of hexaalkyldisilazane, having 0.8-3 organic groups per silicon atom and having units of the, formulae R 3 Si(NH) 0À5 , R 2 SiNH, RSi(NH) 1À5  or Si(NH) 2  in which each R is hydrogen or an alkyl radical of 1-8 carbon atoms, an alkenyl radical of 2-4 carbon atoms, a cycloalkyl radical of 5-6 carbon atoms in the ring, another radical of 6-8 carbon atoms, a benzyl radical, an alkoxy radical of 1-6 carbon atoms or an aryloxy radical of 6-8 carbon atoms, each R' is hydrogen or an alkyl radical of 1-4 carbon atoms or (b) a cyclopolysiloxazane of the general formulae in which each R", is a methyl or phenol radical, at least 40% of these radicals being methyl radicals, m is an integer of 2-5 and each n, which are identical, is 1 or 2. Numerous suitable silicon compounds are listed. The aminosilane, polysilazane or cyclosiloxazane may be used in the pure state or diluted with suitable solvents such as trifluorotrichloroethane or trichloroethylene. Alcohols may be used only when they do not contain any water. They may be applied by immersion, spraying or by centrifuging. Layers of about 20-50A thickness are preferable. The treatment improves the adhesion of a coating of photoresistant polymer that may be applied subsequently from a solution or by centrifuging. The resin may contain photo-sensitisers which decompose under the effect of photons to give free radicals. The applied resin coating is preferably 3000 to 15000 thick. After coating the substrate may be exposed to light rays through a screen for cross linking or depolymerising regions of the resin coating. Non-polymerised or de-polymerised regions may then be removed by a suitable solvent or suitable developing solution.

Title: Improvements in or relating to the manufacture of permanently crimped artificial yarns
IPC: D02G1/02
Filed: 1955-12-22
Abstract: 791,610. Crimping, guiding and tensioning threads. HEBERLEIN & CO., AKT-GES. Dec. 22, 1955 [Jan. 24, 1955], No. 36784/55. Classes 120(2) and 120(3) In the manufacture of crimped threads of synthetic material e.g. polyamides, polyvinyl, or polyesters, by temporarily twisting threads together to form a length of transiently twisted doubled yarn, subjecting such yarn to heat treatment, removing the temporary twist and then separating the threads, the uncrimped threads are fed obliquely to and converge at the length of doubled yarn under tensions that are individually controlled to equality, the angles between the convergent and divergent threads at their entry to and departure from the doubled yarn and the axis thereof are respectively equal, and the angles between planes containing the axis of the doubled yarn and adjacent converging and diverging threads are equal. As shown in Fig. 1, threads 1 and 2 travelling from bobbins 3 and 4 pass through separate thread-tension means 5 and 6, a guide 7, feed rollers 8 and a shield 9 (provided with two guide surfaces, one for each thread, in the form of openings), beyond which the threads converge to form a doubled yarn which passes through a tubular device 10 and is heated thereby (as by steaming under pressure), and thence through a false-twister 11 the doubled yarn passes over a guide pulley 12 and a jockey pulley 13 and the threads are separated by a rod 14, withdrawn by rollers 15, which rotate relative to the rollers 8 at the same or increased speed e.g. to stretch the threads by 0.5 per cent-20 per cent of their original lengths, and wound on a bobbin 16 (or separate bobbins). The length of doubled yarn between the twister 11 and the separation of the threads in relation to the number of turns temporarily imparted thereto may be such as to limit the twist remaining in any short lengths of threads at the point of separation to not more than 1 turn per cm. Figs. 3 and 5, and Figs. 4 and 6 respectively show guides for converging and separating three and four threads by provision of symmetrically arranged apertures and notches in shields 9. In the gate-type tensioner shown in Fig. 7, the thread is gripped between fork-like members 17 and 18 with a force determined by a weight 20 suspended from the member 17 and tending to rotate it about the axis 19.

Title: Improvements in or relating to sludge centrifuges
IPC: B04B1/18
Filed: 1966-08-17
Abstract: 1,099,618. Centrifugal separators. ALFALAVAL AKTIEBOLAG. Aug. 17, 1966 [Aug. 23, 1965], No. 36797/66. Heading B2P. In a sludge centrifuge, the sludge level in the sludge space of the rotor 1 is indicated by means of at least one indicating pipe 13 which extends inwardly from the sludge space towards the centre of the rotor and is connected to a duct 16 extending outside the centrifuge, in which duct are inserted a pressure or flow sensing means 17 and means 18 for intermittently generating a change in the pressure or flow in the pipe 13. The pipe 13 may be connected to the duct 16 either directly by hermetic sealing between a rotary and a stationary sliding surface or, as shown, through a paring chamber 14 and a paring disc 15. The means 18 may be in the form of a piston pump or centrifugal pump, the inlet or outlet of which is intermittently opened by a valve which may be operated by means of an electromagnet. Either the pressure or the suction side of the pump is connected to the duct 16. In operation, liquid may, for example be pumped at intervals by the means 18 to generate a pressure increase in the pipe 13. If the pipe opening into the sludge chamber has been clogged, during such an interval, by a sufficiently large quantity of sludge, the sludge plug resists the pressure increase, and this resistance is indicated by the pressure or flow sensing means 17 which is adapted to automatically effect sludge discharge through openings 3 in the rotor wall by causing a piston valve 4 to uncover the openings. The purified liquid is discharged from the rotor via an overflow outlet 9, a paring chamber 10, a paring disc 11 and a duct 12.

Dec. 30, 1932, No. 36935. [Class 43.] A fastener for buttons or other eyed or shanked articles is formed by bending the ends of a rod 1 to form eyes 2, 3, the rims whereof touch or nearly touch each other at 4 and the substantially straight or slightly convex portion of the rod at 5, 6, thus forming a practically closed triangular space for reception of the eye or shank. The eyes 2, 3 are not completely closed and may be centrally disposed symmetrically with the ends of the fastener. In use, the eye or shank is threaded on the fastener and slid along until it springs into the triangular space. Several such fasteners may be linked together to form a chain as shown in dotted lines.
