Patent FR-1345430-A (FR)
IPC: C08F10/00
Filed: 1963-01-22
Granted: 1963-12-06
Abstract: Substances containing a lower halide of titanium and aluminium halide are formed by reduction of titanium tetrahalide with A1 in the presence of hydrogen halide.  The halide may be chloride, bromide or iodide.  The tetrahalide is present in amount at least stiochiometric with respect to the A1.  The reaction, which is exothermic, is carried out under reflux; liquid diluent, e.g. aliphatic hydrocarbons or chlorinated hydrocarbons, or excess titanium tetrahalide, in which cases the mixture may be heated to boiling point until the reaction starts, or aromatic hydrocarbons, may be added.  The reaction is performed in the absence of moisture or oxygen; an inert atmosphere, e.g. N2 or Ar, may be present. Hydrogen halide, which may be in excess, is passed continuously or intermittently into the reaction mixture.  The A1 is preferably finely divided, e.g. of particle size 0.5 m .  The product is a slurry from which a brown or purple-brown solid may be recovered.  The product may then be milled dry or in liquid, and used with an organo-metallic compound, e.g. a Group I-III metal alkyl or alkyl halide, to form a Ziegler-Nalta catalyst for polymerization of unsaturated hydrocarbons; the metal may be A1. The product may also be used as a feed or addition to a feed in a vapour phase oxidation reactor to form nucleating agents for TiO2, which is prodiced predominantly as rutile.

Title: Improvements relating to electron discharge devices
IPC: H01J19/00
Filed: 1943-01-25
Abstract: 580,004. Discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., and MILNER, C.J. Jan. 25, 1943, No. 1271. [Classes 39 (i) and 40 (v)] The positive grid or control electrode of an electron discharge device is protected from the phenomenon of " blocking " by grid emission, by connecting it to the anode of a triode, the cathode of which is connected to the cathode of the electron discharge device and the grid of which is connected to such a negative potential that triode current does not flow until the potential of the anode exceeds the desired working voltage on the grid or control electrode of the device. The effect is similar to the known use of a diode, but is not limited to potentials near zero. The triode may be within the envelope of the main device. In the application to the electron gun 10, 12, 16, Fig. 2, of a velocity-modulated device, the side 17 of the cathode 10 is made emissive and the triode grid 15 is interposed between it and a depending skirt 14 attached to the control electrode 12, which is supported by a flanged ring 13 co-operating with the anode 16. The invention may also be applied to the screen grids of multi-grid thermionic valves. Specification 483,012 is referred to.

Title: Improvements in or relating to automatic brake-adjusting devices
IPC: F16D65/74
Filed: 1950-01-21
Abstract: 679,742. Hydraulic brake adjustment. DUNLOP RUBBER CO., Ltd., and CHATFIELD, J. E. Jan. 10, 1951 [Jan. 21, 1950], No. 1652/50. Class 103 (i). The invention is concerned with hydraulic means for providing an automatic adjustment of the clearance between the braking surfaces of piston and cylinder operated brakes, particularly disc brakes. As shown in Fig. 1, the hydraulic supply to the main cylinder 2 is from a pipe 7 through an auxiliary or compensating cylinder 1, which may be an integral casting with the main cylinder, and a connecting port 4. A piston 9, having an aperture therein that may be closed by a valve member 10, is slidable in the cylinder 1 against the action of a spring 13 and is limited in its downward movement by a ledge 8. When the brake is released the piston 9 is normally at the top of its movement with its central passage 9A closed by the valve 10 and entry of liquid from pipe 7 causes downward movement of the piston so that the liquid on its other side is driven into the main cylinder 2 so as to cause the main piston 3 to apply the brakes. The cylinder 1 is of such a size that the movement of piston 9 between its limits causes a movement of main piston 3 sufficient to take up the normal clearance. Before the piston 9 reaches its lowest position, the flange 11 on the end of the spindle of valve 10 strikes a spigot 15 and causes the valve 10 to open so as to permit liquid to flow directly from pipe 7 through port 4 into the main cylinder to the extent that may be necessary to make up for any extra movement due to wear of the friction pads. When the brake is released only that volume of liquid displaced by the movement of the auxiliary piston is allowed to flow out of the main cylinder and thus the brake clearance is automatically reset. A modified piston 9 is described in which the valve 10 is normally held closed by a spring star washer element. In the arrangement shown in Fig. 3, a similar value is used, the compensating piston 9 being, in this case, annular and slidable on the rod 17 of the main piston 3. The valve 10 is caused to open, after a predetermined movement, by the action of a flange 27 on its end 21 abutting against a projecting flange on the spigot 26 of the cylinder casting.

Abstract: 909,100. Suspending curtains. KIRSCH CO. Jan. 16, 1959, No. 1667/59. Class 52 (5). An end member 11 supports a hollow curtain rail 12, having a lateral slot 13, and provides a space 36 communicating with the slot and into or from which runners can be moved for addition to or removal from the rail, a gate 37, having a flange forming a blocking member 38, being pivoted on the end member for movement between open and closed positions. Each runner has a curtain-supporting part 19, a slider part 16, and a head 17 which is retained in the cavity in the rail, the rail being telescopically engaged in a channel-shaped arm 22 extending from the end member and detachably locked therein by engagement of a finger 24 in a recess 25 in the rail. The end member is mounted directly or on a wall-bracket and consists of a plate 21 and a flange 26 to which a flange 28 of an L-section pulley bracket 31 is riveted at 30. Pulleys 33, 34 are mounted on the inner side of the bracket 31, the edge of which is recessed to provide the runnerreceiving space 36, and the gate 37 is mounted on the outer side of the bracket 31 which has a stop surface 41 abutting a stop 42 on the gate in the closed position thereof, in which position the blocking member 38 is below the centre line of the slot so that runners, urged by drawcords, press the gate more firmly to the closed position.

Title: Overload protection on x-ray control apparatus
IPC: H05G1/46
Filed: 1942-02-09
Abstract: 552,945. Protective cut-out arrangements. GUNSTONE, A. C., and LAMBERT, R. A. Feb 9, 1942, No. 1688. [Class 38 (v)] An X-ray tube 20 having separate controls for presetting the filament current, tube voltage, and time of exposure, has means for preventing operation of the tube when the three settings selected by the operator are such as would result in damage to, due to overloading of, the tube. The filament is energized by a transformer 4 in series with a tapped resistance 17 controlled by a multi-way switch 5. The tube-voltage is derived from a transformer 3 which is energized by a tapped autotransformer 1 under control of a contactor 8, the tapping of autotransformer 1 being selected by a switch 2. An auxiliary transformer 16 having a tapped secondary has its output adjusted by a switch 6 which is mechanically coupled to switch 5, the arrangement being that, due to the coupling with 5 and to switch 2, the voltage output of 16 is proportional to the tube-input. The output of 16 is connected across a tapped resistance 9, the control switch 10 of which is mechanically coupled to the setting-member 11 of the exposure-timer 12. Part of the resistance 9 applies a bias voltage to the grid of a gas-triode valve 13 having in its plate-circuit the operating winding of a switch 14 controlling the energization of the coil of contactor 8 and an indicating lamp 21. The exposure is initiated by manual switch 15 and automatically stopped by the timer 12, which is preferably of the type employing a condenser/resistance device connected to the grid of a gas valve. For every value of input selected by regulators 2, 5 there will be a limiting time of exposure, and the resistance taps are so selected that, if 11 is preset so that this time is exceeded, the resulting bias blocks the valve 13 and opens switch 14 to prevent energization of contactor-coil 8, at the same time lighting lamp 21. The operation is thus left to the discretion of the operator and the tube can be used to give maximum efficiency without endangering its life. A further regulator 7 is coupled to 5 and 6 so as to provide an additional autotransformer voltage with increase of loading and neutralize the effect of " regulation."
