Title: Process for the heat treatment of ores
IPC: C22B1/10
Filed: 1950-07-24
Abstract: <PICT:0682718/III/1> In a process for the heat treatment of ores as a fluidized bed in a furnace, the feed to the furnace is in the form of a pumpable slurry and the liquid portion of the slurry is separated in the bed.  The amount of water present in the slurry may be regulated in order to control the temperature in the furnace; combustible oil may also be supplied to the furnace, either mixed with the slurry or separately, in order to provide heat.  In the apparatus shown, slurries of finely-divided ore from the top and bottom of the thickener 11 are blended at 14 with filter cake from the filter 13 to provide a slurry of suitable characteristics; this slurry is then pumped into furnace 20 (see Group XII) either above or into the fluidized bed; treated ore is removed at 21.  Examples describe the roasting of iron sulphide ore prior to recovering its gold content, and the calcining of vanadium hydrate to vanadium pentoxide.

Title: Improvements in or relating to automatic quick-motion weighing machines
IPC: G01G1/00
Filed: 1928-06-25
Abstract: 292,934. Toth, S. June 23, 1927, [Convention date]. Indicating -mechanism; pendulum - weight apparatus.-In an automatic weighing machine the rotating pointer spindle is held stationary in space by more than two members all positively moved by parts of the mechanism of the machine, the members having balanced pulls or reactions on the pointer spindle which cause it to rotate without movement in space, stop means being provided, if desired, on the spindle to prevent longitudinal movement. In the form shown in Fig. 1, the load on the platform 1 depresses a lever 4 and by means of a rod 11 rocks two arms 14 connected by a knife-edged track 25 and carrying a pendulum weight 15. The spindle 20 of the indicating pointer 19 rests on the track and is caused to roll thereon by tapes 18, 23 connected respectively to a segment 17 on one arm 14 and to a segment 24 carried by a loaded lever 9 provided for counterbalancing .the platform and its connections. The tapes 18, 23 are attached to cylindrical portions of the spindle of different diameters and wind spirally thereon to permit the pointer to make more than one revolution without fouling the tapes. The successive revolutions of the pointer are indicated by an additional pointer moving with some other part of the machine, such for example, as the rod 6 or 11, the band 18 or 23 or the lever 4, 9 or 14. In a modification, instead of the track 25, the unoccupied arm 14 also carries a segment 17 with a tape passing round the spindle, and a second tape similar to the tape 23 may be carried down to a segment on the lever 9. In a further modification, Fig. 3. the indicator spindle 20 is in rolling contact with the sector 17 and is controlled by tapes 18, 23. In a further modification, Fig. 4, the rolling track 25 for the indicator spindle is carried on a rod 6 connecting the segment 17 with the counterbalance lever 9, The segment 17 may be dispensed with by attaching the upper end of the band 18 to the top of the rolling surface.

Filed: 1953-07-03
Abstract: 725,894. Cutting glass. AMERICAN WINDOW GLASS CO. July 3. 1953, No. 18481/53. Class 56. Apparatus for tranversely cutting a rising ribbon of glass 2 includes a cage 6, 8, 9, carrying the cutter assembly 12, and a stop 110 engaged by the leading edge of the rising ribbon. The stop is carried by a tube 115 having a limited vertical telescopic movement about a stud 120 secured to the cage, and, when the stop is engaged, the limited vertical movement of the tube 115 actuates in sequence, limit switches LS1 and LS3. Switch LS1 clutches the drive from the conveyer rollers 3 to a shaft 16 rotation of which starts to raise the cage. By the time that the tube 115 has completed its limited vertical movement relatively to the stud 120 the raising of the cage is taken over by the upward movement of the ribbon itself, acting through the stop 110 and overrunning the drive from shaft 16. Actuation of switch LS3 produces the movement of the cutter across the ribbon. When the cut has been made the stop 110 is released from the glass, the glass is broken by the operator along the line of score, the cage is returned to zero position and the stop is reset.

The slider 36 moves in a longitudinal groove 38 in the support 34, which may be of anodized Al. Two upstanding walls 40, 42 on the slider loosely span part of a turn of the helix and thus cause the contact to follow the helix. The contact end portion 56 is curved; and it is stated that an angle of " skew " of portion 56 relative to portion 50 of between 3 and 12 degrees reduces the " backlash " effect of reversing the rotation of the shaft. The housing may be of plastics, e.g. phenolic composition. The resistive element may be in the form of a fine wire 20 coiled helically around, bonded to and insulated from a thicker wire 18. Insulation is removed from the element 20 to form a contact track. A calibrated dial or gear may be attached to the end of the shaft 28.

Title: Improvements in high strength refractory filaments
IPC: C04B35/622
Filed: 1966-05-02
Abstract: Boron is coated on to an elongated substrate, e.g. a filament or ribbon, by-passing the substrate at a substantially constant speed through an ambient gaseous composition containing a vaporizable compound of boron whilst maintaining the substrate at a temperature effective to cause decomposition of the atmosphere and cause deposition of the boron on the filament.  The ambient atmosphere may consist of a mixture of a boron halide e.g. BCl3 + H2, and at least a portion of the substrate is maintained at a temperature in the range 1100 DEG K to 1600 DEG K but below the melting points of both boron and the substrate.  Boranes e.g. B2H6 may also be used in the ambient atmosphere, and are particularly suitable when the substrate is of a lower melting point e.g. Al.  The speed of the substrate through the deposition zone is adjusted so as to obtain a deposit of the desired thickness.  Possible substrates are tungsten, rhenium, tantalum, titanium, molybdenum, iron, copper, nickel, "Nichrome" (Registered Trade Mark) aluminium, magnesium, carbon and graphite. X-ray diffraction data indicate that in the above described method the deposited boron reacts with the substrate to give a boride, e.g. with tungsten WB4 or W2B5.  Filaments may be subjected to zone melting to render monocrystalline, and may be treated with HNO3 (see Division C1) to increase the tensile strength of these boron-containing filaments.ALSO:The strength of boron-containing filaments is increased when such filaments are treated with aqueous nitric acid. The filament are preferably treated until 0.5 mil has been removed from the surface of the filament and the preferred acid has a concentration of 40 to 45% by weight and is used at a temperature of approximately 100 DEG  C.  The tensile strength of the treated filaments is at least 500,000 lb./sq. inch. The filaments are prepared as described in U.K. Specification 1,051,883 by passing an elongated substrate at substantially constant speed through an ambient gaseous atmosphere containing a vaporizable boron compound, e.g. BCl3, B2H6 while maintaining at least part of the substrate at a temperature sufficient to decompose the boron compound and deposit boron on the substrate. The atmosphere may also contain hydrogen. Suitable substrates are given as W, Re, Ta, Ti, Mo, Fe, Cu, Ni, Al, Mg, C and graphite. X-ray diffraction data indicate that when boron is deposited by the stated method it combines with the substrate to form a compound, e.g. tungsten boride WB4 or W2B5.
