Title: Method of and apparatus for separating foreign material from a moving stream of material
IPC: B03B4/06
Filed: 1952-10-17
Abstract: 747,849. Separating solid materials. FULLER CO. Oct. 17, 1952 [Dec. 15, 1951], No. 6569/54. Divided out of 747,825. Class 117. In an arrangement for separating foreign substances from a moving stream of material, in which a column of the material is supported on a gas-permeable member and gas is diffused through the said member to fluidize the material thereon, the material is fed from a hopper 12, Fig. 1 on to a member 14 in a conveying duct 11, which supports the material but allows air from a blower 17 to pass therethrough, whereby the material flows by gravity through a container 1, in which the column is maintained, to a receiver 13. A gas permeable member 2 extends across the lower portion of the container 1 and divides it into an air chamber 3 and a material confining chamber 4, air being supplied to the chamber 3 from a source not shown. A hinged closure member 9 provides access to the chamber 4 for the removal of the heavier foreign material. At the junction of the container 1 with the conveying duct 11 a closure 21 is provided for the air chamber 15. The material confined in the container 1 may be placed there prior to the operation of the conveyer or may be collected from the material being conveyed. The heavier material falls through the fixed bed of fluidized material to the surface of the member 2 while the moving bed of material continues through the duct 16 towards the receiver 13.

Title: A new form of tungsten and a process for its preparation
IPC: C22B34/36
Filed: 1964-02-18
Abstract: Tungsten is prepared by reducing WF6 in the vapour state with an excess of hydrogen in a fluidized bed of refractory metal seed particles, which may be of W, Mo, Ta or Nb, at a temperature sufficiently high to bring about reduction of the fluoride and deposition of W on the seed particles.  The particles produced comprise a fine microstructure of tungsten grains having a width and thickness of 0.1-2 microns and length at least six times their width, the microstructure having a Knoof hardness of more than 900, a density of at least 95% of the theoretical density of tungsten and undergoing less than 20% recrystallization upon being subjected to a temperature of 1595  DEG C. for 3 hours.  The particles may be formed into bars or billets by gas pressure bonding, the bars or billets being then rolled, swaged or forged, e.g. to sheet form, or extruded into wire.  The particles may be packed into gas-tight, thin-walled containers which are subjected to gas pressures of 350-1400 Kg./cm.2 and tungsten annealing temperatures, e.g. <PICT:0997153/C6-C7/1> 1090-1930  DEG C., for the production of rocket nozzles and nose cones.  In reducing the tungsten hexafluoride a reactor 3, Fig. 16, may be used, the reactor being formed of high nickel content alloys of copper and nickel.  WF6 and H2 are introduced through lines 9 and 10 and the seed particles through line 11.  Heating means 12 such as electrical resistances, induction heaters or a gas fired furnace, are provided for reaction zone 5.  The reaction temperature may be between 205  DEG C. and 1090  DEG C. but is preferably not over 995 DEG C.

Title: Improvements in Electrical Apparatus for Controlling the Curtains and Lights in connection with the Projecting Screen or Proscenium of a Cinematograph or other Theatre or for like purposes.
Inventor: FALCONBRIDGE CHARLES EARP
IPC: G03B15/08
Filed: 1918-05-07
Abstract: 124,622. Falconbridge, C. E., and Lewsley, J. W. May 7, 1918 Systems c o n - trolling travel for a fixed distance or number of revolutions.-Relates to electrical devices for operating the proscenium curtains of theatres, cinema tographs, and the like. The curtains are operated through cords by an electric motor controlled by a controlling switch in any suitable position. The movement of the curtain cords throws over a reversing switch so that the next operation of the main switch causes the curtains to move in the reverse direction. The motor is automatically stopped when the curtains are fully raised or closed. The motor F drives a pulley G, on which the curtain cords A, B are wound in opposite directions. A swinging arm pivoted at N and carrying a weight M<1> is moved by stops J<2> on a sliding bar J. The bar J works on guides D<1> and is actuated by clips K on the cords A, B. As the arm M moves, it momentarily makes contact with a plate O in parallel with the main switch R, and then moves the reversing switch P, P<1>, Q. The closing of the circuit through the plate 0 produces a short-circuit and allows the controlling switch to be opened by a no-volt release or a spring T, thus cutting out the motor. The lights are controlled at the same time that the curtains are moved by driving a pulley geared to a light-dimming rheostat W in series with the lamps by a band V or by the curtain cords.
