Title: Improvements relating to the distillation and coking of mixtures of solid carbonaceous materials with hydrocarbon oils
IPC: C10B55/02
Filed: 1936-03-20
Abstract: The heat-treatment of mixtures of solid carbonaceous materials, e.g. coal, and liquid hydrocarbon oils to obtain coke and hydrocarbons of low boiling point is carried out by passing the coal-oil mixture through a tube still and then through an externally-heated rotary inclined cylindrical retort, the vapours obtained being condensed at a temperature (about 200 DEG  C.) at which the condensation products are suitable for use as the oil component of a fresh coal-oil mixture.  The tube still is heated to 280--300 DEG  C. when caking coals are used and to 400--420 DEG  C. in the case of non-caking coals, while the retort is heated to 450 DEG  C.  Crushed coal is raised by an elevator 1 to a ball mill where it is reduced to fine powder (50 per cent passing through a 300 mesh screen) which is conveyed by an air current below the surface of the oil in a mixing tank 3.  The powderladen air may be led along a pipe discharging into a larger surrounding pipe 4, Fig. 2, which terminates below the oil level, a portion of the mixture being withdrawn and circulated by a pump 4a so that an injector action is obtained.  The mixture is forced by a pump 5 through the tube still 6 and rotary retort 7 the interior surface of which is scraped by spiked skeleton cylinders 10, Fig. 1a, slung on rods 11.  The vapors evolved pass through a heat-exchanger 12 into a pair of condensers 13 the cooling supply to which is regulated so that a constant outlet temperature of about 200 DEG  C. is maintained.  Condensate from the first condenser passes to a receiver 16 for return to the mixer 3.  Condensate from the second condenser is <PICT:0473886/III/1> <PICT:0473886/III/2> <PICT:0473886/III/3> <PICT:0473886/III/4> <PICT:0473886/III/5> freed from water in a separator 18 and stored in a tank 20 from which it is delivered through the heat-exchanger 12 to the base of a fractionating tower 23 from which crude petrol is distilled off at the top while the bottoms are circulated through tank 25 to a scrubber 21 where they are used to scrub the gases passing from the condensers 17.  Supply of water to the condensers is controlled by a weighted plunger 14 riding on water in a cylinder 15 so as to vary the flow of water to the condenser.  The tube still, Fig. 4, comprises a number of banks 6a, 6b, 6b, of tubes interconnected in zigzag or grid form, the entering bank being heated by radiation. The diameter of the tubes may be increased in stages, e.g. from 2-2\ba1/2\be-3 inches.  Specifications 360,404, 393,601, 393,602, 409,969, 413,927, and 453,265 are referred to.

Filed: 1954-03-25
Abstract: 753,159. Semi-conductor devices. STANDARD TELEPHONES & CABLES, Ltd. March 25, 1954, No. 8697/54. Class 37. In a device comprising a slice of semi-conductor material with a plurality of catswhiskers contacting one face, wherein the slice and catswhiskers are mounted on parallel rods each secured to an insulating body and the whiskers are spaced apart by an intervening insulating sheet fixed perpendicular to the face, the pointed ends of the whiskers are inclined to the sheet so that only their tips touch it. Sheet 12 of, e.g., mica, glass is fixed with adhesive in diametrically opposite slits in a metal sleeve 9 which is forced over the expanded end 8 of rod 7 to which the crystal 10, e.g. of Ge or Si, is soldered after the crystal surface has been lapped and etched. Rod 7 is pushed through metal tube 4 fused or moulded into glass or ceramic base 1 and is positioned by conical part 11 engaging flared end 6 of the tube and a solder connection 13 at the outer end. Rods 14, 18, the ends of which are swaged between V-shaped dies to hold the shaped whiskers, are then inserted through sleeves 3, 5 in the base and the assembly mounted in a jig allowing vertical adjustment of the rods by micrometer screws to vary electrode pressure. The ends of the whiskers are inclined at 10‹ to sheet 12 and are formed with electrolytically sharpened chisel points which bear lightly on the sheet. They may be of Pt, Ag, Wo, Pt-Ru, or phosphorbronze and may be alloyed with significant impurities, e.g. P, As, Sb, Al, In, Au to improve the operating characteristics. Electrode pres. sures are adjusted prior to electroforming, following which they are finally adjusted and fixed by soldering-rods 14, 18 to their sleeves. The cavity formed by sleeve 9 may be filled with wax or an organic insulating compound and a metal cover 21 soldered into channel-shaped ring 2 fused or moulded to the base periphery. In a modification (Figs. 7 and 8) whiskers on rods 30, 31 sealed through an insulating base 22 bear on a crystal 27 mounted on the expanded head 24 of a rod 25 sealed through a sleeve in the base in two opposite corners formed at the intersection of two perpendicular insulating sheets 28, 29 fixed in grooves in the base. Further electrodes may be positioned in the remaining corners. Reference is made to electrolytic sharpening, and electroforming processes described in Specification 747,198, [Group XL (c)].

Title: Method of making magnetic recording materials and materials made thereby
IPC: B29C48/21
Filed: 1973-02-22
Abstract: 1417442 Magnetic recording materials EASTMAN KODAK CO 22 Feb 1973 [24 Feb 1972 9 Feb 1973] 8732/73 Heading B2E A method of making a magnetic recording material (e.g. a flexible disc, belt, sheet or tape) comprises coating a non-magnetisable support with two superimposed layers of viscous liquid-containing magnetic coating compositions and then causing the layers to solidify. A less viscous subbing coating may be present between the support and the magnetic coatings and may comprise a viscous solution of polyvinylbutyral or copolymers of: vinylidene chloride/acrylonitrile; vinyl acetate/ vinyl chloride partially hydrolised and optionally cross linked with a isocyanate; or vinylidene chloride/acrylonitrile/acrylic acid. The viscous magnetic coating compositions may comprise 'the anisotropic magnetic particles of different coercivities, but the same material in a solution of a binder which may be the same in both layers. The magnetic material is typically ferromagnetic iron oxide (e.g. magnetite or gamma ferric oxide), complex oxides of iron and cobalt, chromium dioxide, ferrites, or magnetic metal alloys. Preferred is acicular gamma ferric oxide which is doped with a polyvalent metal such as Co, Ni, Zn, Mn or Cr. Useful binders are: polyvinylbutyral; polyesters e.g. polyethylene terephthalate: polyurethanes; or copolymers of vinyl acetate/vinyl chloride, vinylidene chloride/acrylonitrile, acrylic/methacrylic esters, butadiene/styrene, vinylidene chloride/maleic or maleamid anhydride, cross linked or not cross linked; or mixtures thereof. The binder solution may also contain conventional additives, carbon for conductivity to avoid static and colloidal silica being mentioned. To apply the coatings the viscous magnetic coatings are cast on a layer of the less subbing layer. The layers then slide down a chute Imbricated by the less viscous subbing layer onto a support. Suitable film tape support material is cellulose nitrate or acetate, polyvinyl acetal, polystyrene, polycarbonate, or polyester such as polyethylene terephthalate, and may be biaxially or asymmetrically stretched. Other materials such as paper or metals (e.g. aluminium or brass) may be used.

Title: Improvements in an automatic quick acting circuit breaking device
IPC: H01H77/10
Filed: 1926-03-31
Abstract: 250,570. Branchu, P. J. April 8, 1925, [Convention date]. Electromagnetic switches; sparking, preventing.-A direct-current switch for opening a circuit rapidly against the action of a spring 9 and completing it again when the current falls off comprises a two-part rubber-wound coil 7 for producing a field in the gap between the polepieces 3 in which the end of the light pivoted contact-member 4 is locked. The extended junction of the two-part winding is provided with a contact 10 and is extended to form an arcing horn 12. The contact 10 is normally engaged by a contact 11 on the contact-member and, when the current in the contact-member becomes excessive, the electrodynamic action between it and the field produces the opening movement. In the open position, the contact-member may engage a subsidiary contact 14 provided with an arc-horn 13, and between the main and auxiliary fixed contacts a resistance 23 may be arranged, as shown in Fig. 4, so that in the " open " position of the switch a reduced current passes through the contact-member, this current being adequate, in the event of a shortcircuit, to maintain the switch open until the short-circuit has been removed. The reclosing movement is retarded by a ratchet-and-pawl device 19, 20 in connection with a train of gear wheels. The heavy current is led to the contactmember by means of rubbing brushes 16. In order that the switch may act more readily with rapidly increasing than with gradually increasing currents, the contact-member is shunted by an inductive resistance 24. The rapid-acting switch may be used in series with an ordinary slowacting switch 25, 28, Fig. 4, in which case the two contact-members are interconnected by the rod 30 so that arm 4 can function independently of arm 25, but if arm 25 is opened it causes the opening of arm 4. With this arrangement, the rapid-moving arm 4 opens first with heavy shortcircuit introducing the resistance 23 and, if the current thus reduced is still excessive, the ordinary switch 25 opens the circuit. The arrangement of interconnected switches shown in Fig. 4 may be used as an automatic starting resistance, as shown in Fig. 5. An ordinary contactor Dn is first closed thereby connecting all the resistances 23b, 23a, 23 in circuit. The closure of Dn removes an interlock from the rapid-acting contact D3 and if the current has fallen off adequately this contactor closes and removes the resistance 23b. Similarly, by the successive action of other rapid-moving contactors the other sections of resistance are removed.

A model road vehicle comprises steerable road wheels 13, a spare road wheel 15 rotatably mounted on the vehicle and a steering mechanism for said steerable road wheels, which may be actuated by rotation of the spare wheel 15. A conventional steering wheel may also cause steering movement of the' front wheels. The wheels 13 are mounted on stub shafts 18 secured to the forward end of horizontal links 19, which are pivotally mounted at their forward ends on vertical pins 20 mounted at opposite ends of the front axle assembly 21. The rear ends of the links 19 are pivotally connected to the ends of a link 22, which forms a parallel linkage with the axle. The axle has upper and lower members 23 and 24, the lower member 24 having, midway between its ends, an upwardly cranked portion 25 secured to the upper member 23, the axle thus having forked ends 26. The links 19 are received in these ends. A spring 27 between the, portion 28 of the body 10 and the front axle pushes the underside of portion 25 against an upwardly convex projection 29 on the chassis 12. The axle member 24 is located in recesses 30 in the chassis, allowing the axle movement, limited by stops 31, in a vertical plane, but not horizontally. The steering wheel 17 has a steering column 32 having a cranked end which engages a slot 33 in the link 22. Rotation of the steering wheel thus causes steering movement of the front wheels. The spare wheel 15 is connected to link 22 by a rod 34 which is cranked at each end and is rotatably mounted on the chassis at 35, 36 and 37. The rear end of the rod 38 is received in a forked member 39 extending downwardly from the axis of rotation of the spare wheel, and rotates with the wheel about said axis. The front end 40 of the rod 34 is received in a recess 41 in the link 22. Rotation of the spare wheel thus causes steering movement of the wheels. The rear wheels 14 are mounted on an axle 42 resiliently secured to the chassis by springs 43, which allow the axle to rock in a vertical plane.
