Title: Improvements in the preparation of titanium tetrachloride
IPC: C22B34/12
Filed: 1955-04-18
Abstract: An intimate mixture of carbon and titanium sesquioxide is chlorinated at 3-500 DEG C. to obtain titanium tetrachloride. Suitable forms of carbon include lamp black, petroleum coke and coke breeze; the chlorine may be obtained in the electrolytic decomposition of magnesium chloride formed during magnesium reduction of titanium tetrachloride to metal.  The starting materials may be pure, or the product may be purified.  The carbon and chlorine should be free from water.  It is preferred to use a molar ratio of carbon to titanium sesquinoxide of 3:1.  After chlorination the product may be cooled to condense the titanium tetrachloride, and separate it from chlorine &c., filtered to remove solids such as ferric chloride and conventionally treated to remove other impurities.  In examples the reaction vessel was installed in an electric furnace and connected to a water-cooled condenser which in turn was connected to a cooled receiver arranged to prevent air passing back into the reactor. After charging the solid reactants the reactor was flushed with argon to remove air and moisture and chlorine introduced at about 310 DEG C. In one example the temperature was later raised to 450 DEG C.; in another a mixture of lower chlorides was also found to be present in the product.

Fluid-pressure. - The triple valve described in the parent Specifica.- tion is modified so that, during the release, of the brakes, fluid under pressure is vented from the usual and supplementary brake cylinders in two stages. Conduits 1, 2 correspond respectively to the inlet and exhaust conduits in the slide valve of the triple valve. Conduits 3, 4 lead to the usual and supplementary brake cylinders respectively. In braking a loaded vehicle, fluid under pressure flows from the conduit 1 to the conduit 3 through a port 9 in the triple-valve cock and also through a valve 12 and a conduit 18. As soon as the piston 14 descends, fluid under pressure flows to the supplementary cylinder from a chamber 17 to a. chamber 7 and through a conduit 6. a. port 5 in the triple-valve cock. and the conduit 4. On release of the brakes, the usual cylinder exhausts through the conduits 3, 2 and the supplementary cylinder through the conduit 4, the port 5, the conduit 6, the chambers 7, 17, and the conduits 18, 2, and when the pressure is reduced the piston 14 closes against its upper seat 15 and exhaust takes place from the supplementary cylinder, through the chamber 7, a conduit 19. a chamber 20. and a, port 21. In braking an unloaded vehicle, the cock is turned so that pressure fluid flows to the usual cylinder through a port 8, and the supplementary cylinder is isolated. The conduits 3, 4 and the ports 8, 9 are calibrated to ensure charging the two cylinders in the same period of time.

Title: Storage of photographic developing compositions
IPC: G03C5/26
Filed: 1972-03-13
Abstract: 1358615 Storage of components of photographic developing compositions FUJI PHOTO FILM CO Ltd 13 March 1972 [11 March 1971] 11679/72 Heading B8C A process for the storage of a component of a photographic developer composition comprising a photographic developing agent such as silver halide, a solvent therefor, and a compound which is a source of sulphite ions in an amount of less than 0À15 mole per mole of developing agent, comprises storing the component in a plastics container having a ratio of air-permeation coefficient to the thickness of the container of less than 8À8 Î 10<SP>-10</SP> c.c. (cm.<SP>3</SP>, second, cm. Hg), the container being closed and sealed in an airtight manner. By combining, in this manner, a container having a low air-permeability with a developing agent containing a low concentration of sulphite a relatively stable developing agent is obtained during a satisfactory shelf life. The air-permeation speed q across a film of plastics can be defined by means of Fick's equation: where P 1  and P 2  define the pressure on both surfaces of the film material being tested, A is the surface area of the film, d is the thickness of the film, t is the time, and Q is the permeation coefficient. Some examples of preferred materials are polypropylene, polyvinylidene chloride, nylon 6 and P.V.C., having thickness respectively of more than 2 mm., 0À01 mm., 0À03 mm. and 0À2 mm., polypropylene being the most preferred because of its low cost, good mouldability, and low moisture permeability. A container may be a bottle with a cap or, a tightly sealed bag, or sachet. A container 2, containing a developer component 1, is closed by a cap 3 having a washer 4 of inert elastic material such as raw rubber and made, e.g. of hard polyvinyl chloride. In a modification, Fig. 2, not shown, an inert viscous material paste is applied to the screw-threaded portion of the cap. A pressurefit cap may be provided with a gas-impermeable seal applied around the outside of the cap. When in bag-form the container may be made, e.g. of polyethylene, hydrochlorinated rubber or, polyethylene terephthalate sheet.

[Class 106 (ii)] Comprises apparatus for testing engines in which the engine is put together with the elastic front suspension usual in aircraft engines or with a suitable swing- ing suspension on a heavy, practically freely suspended frame, the masses and springing being so designed that the natural frequency of oscillation in all directions is less than the number of revolutions of the engine at no load. A drum 2 is mounted on a roller bearing 3, the outer ring of which is supported in a resilient ring 4 fixed to the base. The front end of the drum is supported between vertical and horizontal springs 5, 6. Adjustable stops 8, 9 and a shock-absorber 16 prevent excessive vibration. The engine 12 is mounted by means of the usual or a similar front construction 10 on an exchangeable fixing plate 11. A brake 15 is coupled to the engine through a shaft 13 and adjustable couplings 14. Three degrees of freedom of vibration are thus provided and the twisting of the frame about the axis X-X serves as a measure of the torque. In a modification, the weight of the apparatus is taken by a central spring, the torque being taken by side springs, while the disposition of the mass is varied by radially adjustable masses. The test is thus made under conditions resembling those made in actual flying and the engine is less likely to suffer damage than on the usual testing apparatus.
