Title: Wire-type cutting machine
IPC: B28D5/04
Filed: 1974-07-01
Abstract: 1478383 Electro-cutting machine PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd (Philips Gloeilampenfabrieken NV) 1 July 1974 29024/74 Heading C7B [Also in Division B3] A wire-type cutting machine comprises a support 6 for a workpiece to be cut, means for transporting the wire, and means for displacing the wire in a transverse direction consisting of a set 20, 21, 22 of rigid arms in the form of a parallelogram, and means 3, for altering the shape of the parallelogram. The machine has two units 1, 2 which serve for transport of, and applying a braking effect on, the wire, each unit having a disc provided with a groove 23, 24. A right-angled bracket 32 mounted on a cabinet 25 has a plurality of guide wheels 12 while a further right-angled bracket 33 has a roller 8 provided with a plurality of grooves. A similar roller 11 is mounted on the cabinet. Two arms 20, 22 of the parallelogram are pivotally mounted on the cabinet by the shafts of rollers 16, 18. The upper ends of the arms are inter-connected by a link 21 and the lower ends carry rollers 15, 17. The shaft of the roller 18 is rigidly connected to arm 22 and has an arm 10 carrying a counterweight 3. A further plurality of guide wheels 9 are mounted on a plate 36 and the rear surface of a plate 41 has rollers 38, 7 and 19. The wire is led from groove 24 over rollers 19, 7, 38 to guide wheels 9 and the front of plate 41, over rollers 18, 17, 15, 16, 11, 8 and one of wheels 12 to a reversing roller 13. If a single cut is to be effected, the wire is passed over roller 14 and on to unit 2. If a plurality of cuts is to be effected, the wire is fed from roller 14 to another groove in roller 19 and the cycle repeated. The speed of the wire is  controlled by a knob 4 and the tension by a knob 5. The workpiece is mounted on a support 6 adjustable along rods 27 by a screw 26. Cutting medium can be supplied from containers placed in openings in the plate 41. In operation, the workpiece is positioned by movement of the support 6 and units 1, 2 are driven, the wire exerting a force on the workpiece by the action of the counterweight 3. Small counterweights may be connected to the rollers 15, 17. In another embodiment, the parallelogram has four rigid arms and its shape is altered by a counterweight. The counterweight may be so arranged as to cause the wire to engage the workpiece with a constant force. The cutting by the wire may be effected chemically or electrolytically, the wire passing through a container for picking up medium and a rinsing container.

Title: Recovery of fluoride material from used aluminum reduction cell lining
IPC: C01F7/54
Filed: 1955-10-13
Abstract: <PICT:0813834/III/1> Cryolite and/or sodium fluoride and, if desired, sodium metal are recovered from aluminium reduction cell linings by heating at at least 1000 DEG C. at a suitable pressure, and condensing said materials from the resulting vapour.  Preferred temperature ranges are 1050 DEG  to 1300 DEG  C. and pressures of 0.001 to 0.1 atms. and higher are referred to.  The reduction cell lining may consist of the inner carbon lining and/or an outer lining of alumina, insulating brick or magnesia, but when siliceous materials are used they are preferably mixed with the carbon lining; the materials need not be finely ground but often need only be roughly crushed.  In the illustrated apparatus the cell lining material is placed in an evaporator 11, preferably of stainless steel which is arranged in the bottom of a vessel comprising an inner shell 10, also preferably made of steel though graphite is satisfactory, and an insulating outer layer 15 of zirconia or other refractory. The cell lining material is heated to the desired temperature by a high frequency current in water-cooled coil 19 or by direct passage of a current between electrodes in the material or by burning fuel around the evaporator.  The vessel is connected at the top to a head chamber 16 having a connection to a vacuum pump, and baffles 20 and 21, respectively having a ring of holes and a central hole, are provided to assist condensation.  The condensate may be removed by mechanical scraping, for which devices may be provided and if desired, the process may be made continuous by the provision of pressure locks for the addition and withdrawal of material.  The apparatus shown can have an inside diameter of 3.5 ins. and a height of 18 or 28 ins.  The fluoride compounds and sodium are separately collected, e.g. at 24 and 25 respectively, and it is stated to be generally desirable to keep the temperature of the condenser where the vapour contains only sodium at above 98 DEG  C., the melting point of sodium.  Examples are given.

Title: Device for separation of individual ferromagnetic components from a flow of components

Abstract: 1520180 Dispensing articles INST FIZIKI AKAD LATVII SSR USSR and KURGAN PROEKT-KONSTRUKTOR BJURO USSR 14 July 1976 [14 July 1975] 29390/76 Heading B8U A device for separating individual ferromagmagnetic components 6 from a flow of such components comprises a magnet between whose pole-pieces 2, 3 are provided guides 5 of non- magnetic material which define a channel for the components, the gap between the polepieces 2, 3 being such that it narrows in the direction of flow of the components and a lug 7 is provided on the pole-piece 2 at the narrowest position X 1  of the pole gap. In use, components 6 are delivered through the channel by a vibrating tray, for example, and the first component 6 is acted upon by a force F which accelerates the component along the axis X. When the first component 6 reaches the position X 1  the magnetic flux # 1  sharply increases owing to the narrow gap between the lug Y and pole-piece 3 and the presence in that narrow gap of the first component 6, such that the magnetic material of the pole-piece 3 becomes saturated and the magnetic field in the pole gap diminishes accordingly so that the following components 6 are not acted upon by a force F so that the first component 6 becomes separated from the flow of components. The first component 6 can then be removed from the position X 1  for further transportation.

Title: Polymers of ethylenically unsaturated derivatives of ortho-hydroxy compounds and a method for their coloration
IPC: C08F2/22
Filed: 1963-07-25
Abstract: Polymers contain units derived from a monomer of formula <FORM:1043504/C3/1> wherein Y represents an oxy- or carbonyloxy group, X represents a phenyl or napthyl nucleus having said -OH and -Y-R groups substituted thereon in positions which are ortho with respect to one another and R is either a beta-hydroxypropyl acrylate or methacrylate group.  The polymers may contain monomeric units from other ethylenically unsaturated compounds (a long list is given). The polymers may be made by conventional bulk, solution, suspension or emulsion techniques. The polymers act as chelating agents for metals; in Example VI, films cast from a methylacrylate: 2 - hydroxy - 3 - (2 - hydroxybenzoyloxy) propyl acrylate lacquer containing a small proportion of cupric acetate were found to be insoluble in acetone after drying. The polymers may also be reacted with diazonium chlorides to form polymers with dyestuffs bound into the polymer chain.ALSO:Surfaces, for example paper, paperboard and glass, are coated with a polymer containing units derived from a monomer of formula:-  <FORM:1043504/B1-B2/1> wherein Y represents an oxy or carbonyloxy group, X represents a phenyl or naphthyl nucleus having said -OH and -Y-R groups substituted thereon in positions which are ortho with respect to one another and R is either a beta-hydroxypropyl acrylate or methacrylate group.  The polymer can be a homopolymer or contain units from one or more other ethylenically unsaturated compounds (a long list is given).  The polymers are applied as latices or as lacquers in organic solvents. The polymers may be mixed with materials such as cupric acetate to form acetone-insoluble films which are cross-linked by chelation. Alternatively the polymers may be reacted with diazonium chlorides to form polymeric dyestuffs either in the solution or dispersion to be applied as a coating or in the film already deposited.  The dyed polymers may be reacted with ammonia.
