Title: Apparatus for slitting foam sheet material
IPC: B29C44/56
Filed: 1974-03-21
Abstract: 1415992 Cutting apparatus CELLU-PRODUCTS CO 21 March 1974 [22 March 1973] 12698/74 Heading B4B An apparatus for processing a web of foam material 20 comprises a pair of rolls 24, 25 forming a nip through which the material is adapted to pass, the rolls 24 having a plurality or rows of spaced cutting blades 32 projecting radially therefrom and with the blades of adjacent rows staggered, means for advancing the foam sheet drawing means 78, 79 for longitudinally expanding the sheet immediately upon leaving the nip of the pair of rolls to open the incisions and thereby ensure that the advancing sheet will not be retained by the cutting blades of the roll 24. The roll 24 is rotatably mounted in a carriage 34, which is vertically slidable via rollers 56, 58 in frame members 13, 14. Trunnion wheels 36, e.g. of plastics material, are rotatably mounted on the carriage in engagement with the roll 24 so as to prevent deflection of the latter during cutting operation. The anvil roll 25 is rotatably mounted in the frame members 13, 14 and is also supported by trunnion wheels 70, 70. The cutting roll 24 may be pressed downwardly during cutting by-means of pneumatic cylinders 60, 61; the cylinders may also be used to raise the roll from the anvil roll to facilitate initial threading of the foam material between the rolls. The rolls 24, 25 and draw rolls 78, 79 are rotated by an electric motor 72 via chain drives 73, 80, 85 Fig. 3, The carriage may be lifted from the frame for maintainance of the rolls 24, 25 via a handle 68, Fig. 3, after removal of a beam 15. The slit material is wound on to a spindle 83 via a drive drum 84, the roll of material on the spindle being urged into friction contact with the drum by means of spring devices 92.

Title: Improvements in speed governors for prime movers
IPC: H02P23/00
Filed: 1920-05-07
Abstract: 143,502. Taylor, H. B. May 16, 1919, [Convention date]. Differential electric governors; relays.-In a governing system particularly adapted for hydraulic turbines, in which the turbine inlet is controlled through an electric or fluid relay by a differential governor, the controlling shaft 2 is maintained at a constant speed by an electricallyvibrated tuning fork 104 geared to a collar 56 on a small motor 5 driven from the main turbine shaft. A rotary converter on the shaft 2 supplies alternating current to a transformer 111, the secondary of which is in series with a lamp 114 and a double interrupter 115. Alteration of the speed of the collar 56 relatively to that of the shaft 2 moves the pinion 7 and thereby the shalt 8 which carries toothed wheels 11 forming one element of a Root's blower type of oil pump. An adjustable by-pass 17 connects the two ends of the pump, so that a rocking of the casing is produced which, through an arm 31, opens a fluidrelay valve 70 controlling the turbine inlet through a ring 85. The pump casing also carries a re-setting arm 19 operated by the ring 85 through a floating lever 24 connected to a dashpot 30. The outer end of the lever 24 is adjustably connected to a rod 25 supported by springs in a casing 28, adjustable by a hand-wheel 29. These adjustments are stated to allow of the proportion of total load taken by one of several units to be adjusted. The bevel wheel connexion may be replaced by an induction motor, the arms 19, 31 being then carried directly by the shaft 8 which extends from the stator of the motor. In another modification, the oil pump is replaced by a rocking frame carrying a number of coils connected to the generator; inside the frame is a stator carrying a ring of coils and supplied with current at the standard frequency. The arms 19, 31 are carried by this frame which acts in the same manner as the oil-pump.

Filed: 1942-09-10
Abstract: 565,054. Angular bending. SHAW, J. Sept. 10, 1942, No. 12797. [Class 83 (iv)] Formers.-In bending a section bar 5 about a die 1 with a web 5b projecting inwardly, this web is pressed during the bending operation into a recess 6, Fig. 2, in the radial face of the die, which is undercut to accommodate the wrinkled form produced. These wrinkles are then flattened, e.g. by pressing between a flat plate and a flat bolster around the edge of which the bent bar is placed. The die 1 has two plates 3, 4 loosely attached to it by bolts 9 but held close during bending by catches 10. ' The bar is clamped to the die by a detachable clamp 16 and is engaged by a bar 19 adapted to slide longitudinally in a head 20 adjustable along the arms 15 of a hand lever 14 pivoted at the centre of curvature of the die by a removable pin 11 which is secured by a catch. The movement of the lever is limited by a stop 24. After bending, the pin 11 and lever 14 are removed, the catches 10 are swung back and the plates 3, 4 drawn apart to release the bent bar. To make bonds of opposite hands, the arms 15 are made wide enough to have holes for the pin 11 opposite the upper as well as the lower roller 21, Fig. 1, one hole being used when making clockwise and the other counterclockwise bends.

Title: Process for producing titanium dioxide concentrates and other useful products from ilmenite and similar ores
Inventor: SHIAH CHYN DUOG
IPC: C22B34/12
Filed: 1965-03-30
Abstract: Iron is removed from a TiO2 containing ore by roasting the ore in an oxidizing atmosphere to convert all the iron to Fe2O3, reducing to convert the Fe2O3 to Fe metal, and leaching with a ferric salt solution to give an iron-free TiO2 residue and a ferrous solution, which is oxidized with an O2-containing gas at above 20 DEG  C. to regenerate the ferric solution.  The ore oxidation may be effected at 750-1200 DEG  C. in air, and reduction at 700-1300 DEG  C. with carbon, CO, or H2, or mixtures, e.g. CO + H2. Leaching may be effected at 80 DEG  C. with aqueous or alcoholic FeCl3 or Fe2(SO4)3 of at least 12% concn. The ferrous solution may be oxidized with oxygen and optionally ozone at 80 DEG  C., giving by-product Fe2O3. Part of the iron may be retained in the ferrous state in the solution used for leaching, e.g. in the FeIII:FeII ratio of 1.5:1. The ore may be ilmenite, and the product is referred to as "synthetic rutile."

[Class 39 (i)] [Also in Group XXII] In a cathode-ray tube for the reproduction of pictures in television a modulated beam from a gun 4 is focused and deflected by the usual means and is further bent by a pair of coils 7 to impact a cathode 8 ; the resulting emission from this cathode is directed by the electron-optical system 10, 11 and coils 7 on to a screen 12, which is raised thereby to incandescence to give the desired picture, this being projected by an optical lens 14 on to a viewing screen. Both cathode 8 and screen 12 may be independently heated ; the latter may be by a constant component of electron bombardment from the cathode 8. The applied potentials are as follows : cathode 4 -300,000, electrode nearest thereto -20,000, cathode 8 and electrode 11 earthed ; anode 10 1,000 and screen 12 5,000. The screen 12 may be formed of a sheet of nickel or tantalum coated with a thin layer of lamp black by smoking with a candle; finely divided tungsten is then shaken on this lamp black and the screen is degassed by acting as the anode of a diode to a temporary tungsten filament. The cathode 8 may comprise a coating of barium and strontium on a nickel base 8a formed of two plates, with an independent heater 8a having mica insulation 8b; this is degassed in a bulb separate from the cathode-ray tube. In place of nickel tungsten, molybdenum, tantalum or palladium may be used and with a tungsten base the tungsten is first oxidized and then coated with barium or caesium. According to the second Provisional Specification palladium, platinum, gold, silver and aluminium may also be employed. Specifications 486,657 and 486,915 are referred to. Metal foil.-To make a thin foil the metals specified for the cathode 8, a strip of, say, tantalum is wound round a tungsten filament which is mounted in a glass envelope ; one end of this filament has a spring part to allow for expansion in action. A nickel cylinder is mounted in the envelope and surrounds the filament which is electrically heated, after evacuation of the envelope, to vaporize the tantalum; when this has been completed the nickel cylinder with adherent tantalum is treated to remove the nickel, either chemically or electrically. Supports are added to the tantalum foil before the last treatment.
