Title: An improvement in or relating to textile waste-opening and other textile fibre processing machines
IPC: D01B3/02
Filed: 1950-11-25
Abstract: 722,798. Magnetic separators. EARNSHAW, A. Nov. 26, 1951 [Nov. 25, 1950], No. 28873/50. Class 117. A magnet bar for use in a textile waste-opening or other textile fibre processing machine comprises a series of permanent horseshoe magnets e secured by their crown portions to the underside of a bar a adapted to extend across the width of the machine, the arrangement being such that the poles of the magnets alternate continuously along the bar and provide a magnetic field between the legs of each magnet and between opposed legs of adjacent magnets. The part g of the bar may be of non-magnetic material, and its position relative to the pins f of the rollers may be adjusted by using any of the holes a<SP>2</SP> for its mounting, and by adjustment of the bolt d, the shaft b being slidable in an open slot in the bracket c. The bar may be thus allowed to rock about the shaft b to allow any large tuft of material to pass. In the treatment of fragile webs of fibres a plastic shield may be arranged to cover the magnet poles to present a smooth surface and prevent the material being drawn into the spaces between the poles.

Title: Friction wheel screw press
IPC: B30B1/18
Filed: 1954-10-12
Abstract: 754.307. Reverse gearing. ELSEN. R. T. Oct. 12, 1954 [Oct. 13, 1953], No. 29360/54. Class 80(2) [Also in Group V] In a press, a flywheel 2 drives a screwed spindle 3 to lift a movable press jaw 27 to the operative position, and is rotated in either direction by a reversing gear comprising friction wheels 22, 23 and 25, 26, the wheels 22. 23 rotating with an electric motor driven spindle 21, and the wheel 22 engaging the friction wheel 25 which is fast with the friction wheel 26. The friction wheels are rotatably mounted on levers 19, 20 &c. rockable to engage either the wheel 23 or the wheel 26 with the inside rim of the flywheel 2 depending on the direction of rotation required. According to the invention, the rockable levers 19. 20 &c. are so mounted on brackets 4 that they can be easily raised to lift the wheels 22 &c. out of the flywheel, so that the wheels can be replaced when worn. The brackets 4 carry bushes 5, 6 connected together for rotation by an expansible link 10 and turned on operation of a handle 14 connected thereto by links 11...13. Arms 15, 16 rest on top of the bushes 5, 6 and have projections 17 engaging corresponding recesses in the bushes. The rocking levers 19, 20 are secured to the arms 15, 16 so as to be axially displaceable by threaded spindles 18, and carry the friction wheels 22 &c. A bridge 37 on the rocking lever 20 carries an electric motor 38 -driving the spindle 21. On operation of the handle 14. either the wheel 23 or the wheel 26 is engaged with the inner edge of the rim of the flywheel 2. Turning the threaded spindles 18 adjusts the positions of the rocking'levers 19, 20 and wheels 22, 25 &c. to compensate for wear of the friction surfaces. The bushes 5, 6 and arms 15, 16 have bores tapped to receive threaded spindles 30, the reduced ends of which rotate in small holes in and abut the rocking levers 19, 20. Collars 31 are secured to the reduced ends of the spindles 30 and hold the projections 17 of the arms 15. 16 in the corresponding recesses in the bushes 5, 6. On releasing lock nuts 35 and screwing the threaded spindles 30 up their tapped bores, the arms 19, 20 are raised to disengage the projections 17 from their recesses and the wheels 22 &c. are simultaneously raised above the level of the rim of the flywheel 2. The friction wheels 22 &c. can then be swung away from the flywheel 2 and, if worn, can be replaced by others.

The two side walls may be telescopically extensible by means of selfcontained lifting tackle. As shown, each wall consists of panels 1, 2, 3, panel 2 carrying grooved guiding rollers 4. A cable wound on drum 12 (rotated by winding gear, not shown) passes around pulleys 8, 9 attached to panel 1, then around pulleys 10, 11 attached to panel 2 and has its end attached at 13 near the bottom of panel 3. Winding of the cable on to the drum 12 causes automatic extension of the side wall. End panels 5, 6, 7, roof trusses 16, 18, and roof bracing members 21, 22 are raised into position by means of pulleys 15, 19, 20 which can also be used to raise roof panels. A single building comprises one or more such assemblies with end sheets such as 5, 6, 7 covering the open ends. The building may also include a gantry rail from which a platform carrying lifting tackle may be suspended. The side walls are mounted on wheels 29 or on trucks.

Abstract: 863,331. Distilling zinc. COMPAGNIE DES METAUX D'OVERPELT-LOMMEL ET DE CORPHALIE. Sept. 15, 1958, No. 29492/58. Class 82(1) [Also in Group XI] A charge consisting of a reducing agent, e.g. carbon, mixed with a porous and unsintered zinc oxide ore material in a granular state or finely divided form is heated by Joule effect when located between electrodes provided in a rotatable drum 4, the current being controlled to maintain the temperature of the charge below that at which the particles of the charge commence to stick to one another. The mixture, which may be a mixture of roasted blende and reducing agent may be preheated before passing into the drum. Refractory bricks or the like impervious to zinc vapours form an inner lining and a layer of heat-insulating material is also provided. Two pairs of electrodes 5, 5 and 6, 6 are preferably of refractory steel and are located on electrically non-conductive layers 7 of refractory material. The electrodes may have fins and an outlet 8 may have a screw-like device for hastening the extraction of the material. Current supply to the electrodes is via circular bands 9, 10 and brushes (not shown), the two electrodes in the centre of the drum having the same polarity and voltage; the drum may comprise a single compartment having one pair of electrodes, or more than two compartments and two pairs of electrodes. Pyrometers 22, 23 are used in regulating the current supply to maintain a constant temperature which for flotation blende my be between 1050 and 1080‹C. Roasted blende grains of about 0.5 to 3.5 mm. may be obtained by granulation of crude fine blende and subsequent roasting in a fluidized state at temperatures between 950‹ and 1050‹C. The excess carbon reducing agent and the gangue of the ore accumulates and is cooled in a hopper 11 in a neutral or reducing atmosphere and the zinc vapour, together with CO, passes into a cyclone 14 for separation of any solid material. Liquid zinc is collected in a condenser 17 and the CO is extracted at 19. Some of the CO may be cooled and injected in a hopper 1 at 24. A voltage of 110 to 500 is specified and the capacity of the compartments containing zinc which has been almost completely reduced may be increased to ensure that each compartment absorbs the same amount of energy. The gangue may contain metals other than zinc or cadmium and be subjected to magnetic separation to obtain carbon and iron. Rotation of the drum may be reversed from time to time. The process may be carried out in a plurality of small cylinders arranged in series, the zinc vapour being collected separately after each reduction process. Prior purification of the zinc ore may be effected by feeding a reacting agent, e.g. NaCl, to the first cylinder, to remove Pb. The speed of the reaction in different cylinders may be controlled by feeding regulated portions of reducing coal into two or more of the cylinders at the beginning of the series. The electrodes may be of stainless steel.
