Abstract: 952,950. Developing latent electrostatic images. GENERAL ANILINE & FILM CORPORATION. Feb. 28, 1962 [March 1, 1961], No. 7811/62. Heading G2H. A sheet carrying a latent electrostatic image is developed in an apparatus comprising a casing containing ferromagnetic powder, means for moving the sheet through said casing, two magnetic applicators for successively applying the powder to the sheet and means controlled by the movement of the sheet causing application of powder to the sheet by the first applicator and then by the second applicator while discontinuing application by first applicator. In the Figure, sheet 16 is passed over rotating cylinders 20 and 21 which are studded with magnetic cores carrying powder 23. Each cylinder is provided with a rotary gate 32 and 32<SP>1</SP> having a flat side 33 and 33<SP>1</SP> allowing passage of the developer bristles 19. Both gates are attached to a shaft connected to a solenoid (not shown) which controls the movement of the gates. When the gates are in the position shown the leading edge of sheet 16 actuates microswitch 44 energizing the solenoid and causing gate 32 to close and gate 32<SP>1</SP> to open thus limiting the amount of powder applied by the first cylinder 20. When the leading edge of the sheet closes microswitch 45, the solenoid is actuated and closes gates 32<SP>1</SP> and open gate 32 thus stopping the flow of powder on to cylinder 21 and leaving the apparatus ready for the next sheet. A pair of fixed scrapers 35 remove any residual charge from the cylinders. The two cylinders 20 and 21 are preferably rotating in opposite directions and the powder is continuously agitated by two shafts 24 and 24<SP>1</SP> rotating in opposite directions.

Patent GB-933407-A (GB)
Title: Preparation of fibrous titanium dioxide
IPC: C04B35/622
Filed: 1961-03-03
Abstract: Fibrous titanium dioxide is made by oxidising titanium subhalide in a fused mixture of halides of metals of Group Ia and IIa of the Periodic Table, excepting that if the halide of titanium is the fluoride, the melt shall comprise halides other than fluoride.  There may also optionally be present in the melt titanium metal.  A suitable titanium subhalide mixture can be provided by the partial reduction of titanium tetrahalide with an alkali metal.  Other suitable starting materials are disclosed in U.S.A. Specifications 2,920,952, 2,706,153, 2,765,270, 2,835,568, 2,845,341, 2,856,335. The alkali metal halide melt may be sodium chloride or a mixture of metal halides which melts at the desired reaction temperature of 550 DEG -1000 DEG C., preferably 600 DEG -800 DEG C.  The presence of a fluoride improves fibre length of the product. Suitable melt constituents include LiCl, LiF, KCl, KF, NaCl, NaBe, NaI, CaCl2, BaCl2, MgCl2, and ZnCl2 and CdCl2 may also be present.  The oxidation can be operated at atmospheric, sub and superatmospheric pressure with preferably dry air or oxygen; minor amounts of water although undesirable can be tolerated.  The oxidation can be effected by bubbling the gas through the melt or passage over the surface thereof.  The titanium dioxide fibres may be separated from the melt by settling and decantation from the molten magma, followed by washing with water to remove adhering salts or alternatively treating the cold, solidified melt with water to remove the salts by dissolving.  The product is used as a high temperature thermal insulator, filtering medium or reinforcement in ceramics.  In a typical example, a fusion dried mixture of sodium and potassium chloride, contained in a silica reaction vessel had added to it under a dry nitrogen blanket a sodium chloride titanium subhalide mixture. The contents were fused and heated to 715 DEG -740 DEG C. and dry air was passed over the surface for 454 hours.  The cooled mixture, after completing the reaction, was treated with water to remove soluble salts to yield after grading fibres of titanium dioxide 0,2-1mm. long, 1 micron in diameter.

Title: Improvements in or relating to the preparation of polymers and copolymers having a base of vinyl chloride
IPC: B01F7/16
Filed: 1964-02-26
Abstract: The bulk homopolymerization or copolymerization of vinyl chloride is carried out while maintaining a high speed of agitation in a first stage until a degree of conversion of 7 to 12% is obtained, then the speed of agitation is reduced during a second stage of the reaction to a low value which is still adequate for proper temperature control of the reaction, until completion of the reaction.  In a preferred embodiment the low speed of agitation is maintained until a conversion of about 40% has been obtained and the speed of agitation is then increased to an intermediate speed until completion of the reaction. Apparatus suitable for carrying out the process of the invention is described and illustrated, and may comprise autoclaves provided with ribbon, complete or partial frame, anchor, turbine or bi-cone agitators which may be rotated at different speeds, or autoclaves provided with two agitating means, e.g. bi-cone and anchor agitators, to provide different speeds of agitation.  The position of the fast agitator may be varied, e.g. it may be withdrawn from the reaction mixture when slow agitation is commenced.  Examples describe the polymerization of vinyl chloride in the presence of azodiisobutyronitrile and mixtures of azodiisobutyronitrile with isopropyl peroxydicarbonate, and the copolymerization of vinyl chloride and vinyl acetate in the presence of azodiisobutyronitrile, by the process of the invention and by comparative processes in which the speed of agitation is constant.

Title: Improvements in or relating to centrifugal separating apparatus
IPC: B04B1/18
Filed: 1920-03-18
Abstract: 164,867. Sturgeon, R. A. March 18, 1920. Density separators; discharging.-In a separating-apparatus relative motion is obtained for discharge purposes, between the chamber and its end wall by the variation of the pressure produced by centrifugal force in a liquid admitted to the space between the movable member and an end cover fixed to the shaft. The chamber B, Fig. 1, has an integral end wall C and can move axially within the fixed dome E, the end C acting as a piston or being connected to the dome by annular diaphragms. The lower end of the chamber engages an annular seating D<1> on the face of the end cover D fixed on the shaft A. Liquid is admitted by the pipe F to the space between the dome E and the chamber end C, and the pressure keeps the chamber upon its seating. The liquid to be treated enters the upper end of the hollow shaft, passes through the openings A<1> over the weir A<2> into the chamber B, and after depositing its solids upon the chamber wall escapes through openings H in the end D and flows into a channel in the foundation of the apparatus. To discharge the solids, the supply of liquid through the pipe F is stopped, and as the liquid passes through the openings E<3> the pressure on the end C diminishes until the springs D<2> raise the chamber B, which is then swilled out to discharge the deposited solids. A filter 0 of any suitable material may be arranged in the chamber as shown. In a modification the chamber is integral with the shaft and the lower end plate is movable and is held in by the pressure of liquid supplied through the pipe F. Two separate sets of openings for the discharge of clarified liquids of different specific gravities are made in the shaft and are separated by a baffle. In another modification a receptacle M, Fig. 3, for grease recovery is placed at the lower end of the shaft; the grease passes through discharge openings M<1> in the shaft into the vessel M and the clarified liquid passes into the annual conduit N. The solids are swilled out as in the arrangement shown in Fig. 1.

Abstract: 782,292. Valves. WIEGEL, H. P. March 23, 1955 [March 24, 1954], No. 8466/55. Class 135. In a valve comprising a chamber 4, a main valve 22, 25 and 26 and an auxiliary valve 10 slidably mounted in the chamber 4, the main valve being manually movable against a seat 15 carried by the auxiliary valve 10, the latter is movable against a fixed seat 9 in the chamber by the manual operation of the main valve 22, 25 and 26 and automatically movable away from the seat when the main valve is moved away from its seat by a combination of spring and gas pressure when the latter drops to a predetermined value. Oxygen at high pressure, passes into a bore 3 by way of a filter 38 and from thence flows into the chamber 4 via a groove 17 and ports 18; to open the valve a handle 34 is turned through less than one revolution whereby the main valve comprising a sleeve 22, a disc 25 and a washer 26, is opened by being screwed to the right, thereby opening the bore 12 and allowing the gas to pass therealong into the outlet 5, the valve 10 being held on its seat 9 by the gas acting on the seat 15 in opposition to the action of the spring 14. When the pressure in the bore 12 and hence to the left of the valve 10 has increased sufficiently to move the latter to the right with the aid of the spring 14 the seat 15 again engages the rubber washer 26 and gas in greater quantities is able to flow to a reducing valve, not shown, via groove 17, ports 18 and outlet 5. Should a leakage occur downstream of the valve orifices 20 will throttle the gas flow so causing the valve 10 to again abut the seat 9. The handle 34 is rotatable along a pressure calibrated scale, not shown, so that the main valve can be set to open for longer periods as the pressure in the oxygen cylinder decreases. The orifices 20 in the collar 19 of the sleeve 16 may be replaced by a narrow passage, not shown, extending from the groove 17 to the end surface of the sleeve 16 near the seat 9; the passage is formed by a groove in the sleeve or by making the latter a loose fit in the bore 4.
