Abstract: 1,051,845. Refining glass for the manufacture of sheets. GLAVERBEL. Aug. 27. 1963 [Sept. 29, 1962], No. 33941/63. Heading C1M. In a process for refining glass during the continuous production of sheet glass, glass in an unrefined state is drawn from a melting tank and is spread out on a flat, metallic horizontal surface in a thin liquid layer the depth of which is substantially that of the sheet to be obtained in a zone maintained at a temperature sufficiently high to promote rapid refining of the glass, the glass layer then being advanced through said zone and thereafter through a progressive cooling zone where the glass is firepolished and solidified to form a sheet-like ribbon or strip, which is then passed into an annealing furnace. Unrefined glass is withdrawn through an outlet 1 of a melting tank and is fed over a weir 8 on to a flat horizontal surface of metal which is either a flat metal sheet 10, e.g. of molybdenum Fig. 1, or the surface of a bath of molten metal 14 (e.g. silver or silver alloy with a metal such as copper or tin, or tin or tin alloy and a metal such as copper or lead), Fig. 2 (not shown}, which forms the firing zone 3. The glass spreads out to a thin liquid layer and is maintained at a high temperature to refine it by using auxiliary heating elements 9, or 9 and 15 (Fig. 2). When the glass layer has been advanced through this firing zone it is passed on to the surface of a bath of molten metal, e.g. tin, or tin alloy, 16 in a separate zone 4, the temperature of which progressively decreases towards the exit by cooling means 17 wherein the glass layer is fire-polished and progressively cooled to become a ribbon or strip which is solid enough to be removed by rollers 22 without deforming into an annealing furnace. The zones 3 and 4 are separated by a screen 7 and a weir 23, Fig. 2. The metal surface 10, or molten metal 14 must not react with the glass or refractory and be non-oxidizable. Means are provided for preventing oxidation of the molten metal bath in zone 4.

Abstract: 1,052,067. Melt-spinning. IMPERIAL CHEMICAL INDUSTRIES Ltd. Nov. 2, 1964 [Nov. 28, 1963], No. 47105/63. Heading B5B. In the melt-spinning of filaments from polyesters, the temperature of the air close to the filaments is controlled so that the minimum temperature T 1  of the air close to the filaments in the controlled region is expressed by T 1  = T 2  - 9X + 30, where T 2  is the temperature of the spinneret and X = 10<SP>4</SP>D/FS, where D is the distance in feet from the spinneret at which T 1  is measured, F is the denier per filament of the spun filaments and S is the wind-up speed in feet per second, and the maximum temperature close to the filaments in the controlled region is not more than T 1  + 100, the control being continued until the temperature of the air close to the filaments has attained a value of T 2  - 150‹ C. to T 2  + 40‹ C. Preferably, the air temperature close to the filaments increases with distance from the spinneret above the spinneret temperature (T 2 ) and thereafter falls. The control of the temperature close to the filaments may be obtained by use of a heated shroud surrounding the filaments, the temperature being measured by thermocouples placed as close to the filaments as practicable without touching them. Examples describe the spinning of polyethylene terephthalate having intrinsic viscosity at least 0À75.

[Also in Division C2] In examples the preparation of rhenium, molybdenum, cobalt and nickel selenides and of rhenium telluride is disclosed. The first three selenides and rhenium telluride are prepared by a precipitation method involving the action of hydrogen selenide or hydrogen telluride on rhenium heptoxide in NaOH, ammonium paramolybdate, a complex cobalt-ammonium nitrate and rhenium heptoxide in NaOH respectively. Nickel selenide is prepared by the reduction of nickel selenite solution, prepared in situ from selenium in conc. nitric acid and nickel nitrate hexahydrate, with hydroxylamine hydrochloride and ammonium hydroxide. Cobalt and nickel tellurides may also be prepared by precipitation using hydrogen telluride and cobalt or nickel nitrate in NH 4 OH.

Abstract: 1,230,042. Change-speed control. HONDA GIKEN KOGYO K.K. 6 Feb., 1969 [7 Feb., 1968], No. 6578/69. Heading F2D. The hydraulic actuating pressure of a friction controlling element (not shown), such as a clutch, of an automatic change-speed gear (not shown) of a motor vehicle is augmented by the torque reaction on the stator 4 of a hydrodynamic torque converter 1 through which the change-speed gear is driven from an engine (not shown), so that additional friction pressure is available at the controlling element at times when the torque demand is greatest. The hydraulic control pressure is supplied from an engine-driven pump 6 via a pressure-control valve 12 movable against a spring load 13 by excess fluid pressure, acting through a backfeed 15, to open a vent 11 for pressure control, and movable to close said vent by the spring load 13 reinforced by a reaction load detector responsive to the stator torque reaction according to output torque of the converter. The spring load 13 comprises nested springs 13a, 13b the latter of which has a clearance 14 on the valve end such that it is inoperative for the initial movement of the detector 5 during low torque reaction at the stator.
