Abstract: 1,183,437. Carbon. NORTH AMERICAN ROCKWELL CORP. 8 July, 1968 [6 July, 1967], No. 32544./C8. Heading C1A. A process for forming a composite in which parapolyphenylene, with or without additional C and/or graphite is reinforced with fibres of B, Ta, Ti, W, Mo, compacted at a pressure between 1000 and 120,000 p.s.i. and then pyrolysed at a temperature of between 650‹ and 2500‹ C. Pyrolysis is carried out either under a partial vacuum or an inert atmosphere. Reinforcing materials may be in the form of fibres with a ratio of length to diameter of between 10 and 1000. Fibres can be randomly dispersed or can be aligned in the graphitic structure. The above reinforcing materials are satisfactory at temperatures of between 900‹ and 1400‹ C., however above this temperature range carburization weakens the fibres and therefore they may be coated with a carbon diffusion resistant metallic coating of preferably Re, Rh, Ir. After manufacture the composite can be machined.

Abstract: 1,216,116. Fluid-pressure brakes; valves. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 8 July, 1969 [10 July, 1968], No. 32816/68. Headings F2F and F2V. The brake valve of Specification 1,174,243 shown in Fig. 1, is modified by a loading magnet, Fig. 2, responsive to two or more variable quantities, e.g. speed and load of the vehicle to which it is fitted. The valve has an exhaust port 7 providing a seat for a throttling valve member 13 so as to set up a control pressure at an outlet 10, which is in permanent communication with a supply conduit 26 through a restrictive choke 25. The valve member is engaged by a cantilever leaf spring 14 which is loaded by a magnet 51 to determine the control pressure. Magnet 51 comprises a coil 18 carried by the spring and moving in a gap between a pole 52 and core 53. An end cap 55 supports the core and a permanent magnet 56. Additional windings 57 and 58 are provided to modify the field in accordance with the variable quantities. In a railway vehicle the coil 18 could be controlled by the driver and the windings 57 and 58 could modify the displacement of the magnet in accordance with the speed of the train and the weight of the coach. The permanent magnet can be replaced with an electromagnet excited with a constant current. In Fig. 3, not shown, the coil 18 reacts to the field of three windings (59), (60), (61). A core (53), Fig. 4, not shown, is displaceable between poles (52) and (66) by fluid pressure in a chamber (62). The braking system shown in Fig. 5 is disposed on trailer vehicle, e.g. a railway vehicle, incorporating the brake valve 78 to control a valve 76 and brake cylinder 77. Air from a reservoir 73 is supplied to valve 76 via a conduit 75, and a branch 79 feeds valve 78 to control valve 76 via a conduit 80. The coil 18 in valve 78 is controlled by the driver via a line 81 from, e.g. the driver's cab, a winding 82 is controlled over line 83 from a speed-sensitive device, which can be on the trailer, and the winding 84 is responsive to a transducer 86 in accordance with the load of the vehicle. In Fig. 6, not shown, three vehicles (88), (89) and (90) are controlled from a control point (91) by A.C. control signals which are converted to D.C. by rectifier bridges (92), (94) and (96) respectively located on each vehicle.

Title: Improvements in zinc ferrite pigment
IPC: C09C1/22
Filed: 1955-11-21
Abstract: A non-ferromagnetic pigmentary zinc ferrite of formula ZnO.Fe2O3, containing no zinc oxide in excess thereof, is prepared by heating a homogeneous mixture of Fe2O3 and ZnO in substantially equimolar proportions with no excess ZnO, to a temperature of 750-1000 DEG  C. for 10 to 30 minutes in the presence of a chloride catalyst which is volatile at the treating temperature.  The product is homogeneous, yellow and substantially free from water-soluble salts; the crystals are cubic of spinel structure, and the particles are acicular with a length of 0.4 to 1 micron and a diameter of 0.1 to 0.2 microns. The ferric and zinc oxides starting materials may be supplied as such or as the carbonates, or alternatively the sulfates may be mixed, in aqueous solution and a mixture of iron and zinc carbonates precipitated therefrom with sodium carbonate. Preferably ferric oxide and zinc oxide are mixed with water to form a homogeneous slurry which is de-watered, filtered and the solids dried at about 100 DEG C. before calcining.  After calcination the product is preferably cooled slowly to 400-500 DEG  C. before grinding. according to examples: (i) ferric oxide hydrate was slurried with water to a 15 per cent solids content and a second similar slurry of zinc oxide was prepared.  The slurries were separately freed from aggregates and then thoroughly mixed for several hours.  After careful checking of the iron oxide analyses, the slurry was de-watered by filtering and the solids treated with a small amount of an aqueous solution of zinc chloride.  The paste obtained was extruded as small pellets which were then dried at 100 DEG  C. and calcined in a rotary furnace at 850 DEG  C. for 20 minutes.  The pellets leaving the furnace were gradually cooled in an electrically heated screw conveyer to a temperature of 400 DEG  C. in about 10 minutes and the resulting pellets were ground to a fine powder.  (II) An aqueous solution containing iron and zinc sulfates was formed and analytically checked, and was then heated to 75 DEG  C. whereupon sodium carbonate was added to precipitate the iron and zinc as the corresponding carbonates.  After evolution of carbon dioxide had ceased the precipitate was de-watered, washed and dried at 100 DEG  C.  The dried lumps were heated for 20-30 minutes in a furnace at 800 DEG  C. in an atmosphere of oxygen containing a small amount of hydrogen chloride.  The resulting zinc ferrite was cooled slowly whilst remaining in the oxygen atmosphere and was thereafter ground.  A very slight excess of ferric oxide in the range of 0.4 to 0.6 per cent by weight may be employed in the initial reactants.

Abstract: 637,691. Mixing appliances. BAKKER, J. Dec. 23, 1947, No. 34035. Convention date, Jan. 9, 1946. [Class 86] Apparatus for mixing concrete, &c., by dividing a stream of materials and then re-uniting it comprises layers of funnel like containers arranged so that the outlet of each opens into the inlet of more than two similar containers in a layer below, the materials being finally collected together. Fig. 2 shows an arrangement of frusto-pyramid containers 4, 5, 6 each container opening into four in the layer below, the materials being collected in a trough 7. The apparatus may operate as a batch mixer, or as continuous discharge apparatus, and water may be fed in through sprays at some stage in the mixing, the containers then being vibrated to assist the passage of the pasty materials through them. A modification of the apparatus, Fig. 5, is a batch mixer provided with containers 10, 11, &c., mounted on rubber cushions 21 in a housing 16. The containers are arranged so that the spaces between containers in each layer, e.g., 13, form similar containers when the layer is inverted. A gravity operated valve such as a ball 14 closes each of the outlets of these inverted containers. In operation, the materials are fed into the machine at the top, from where they pass through containers 15, 10, 11, &c., to the bottom, water being sprayed into the machine at some suitable stage. The housing and containers are then inverted, and the semi-mixed materials pass back, the gravity operated valves falling to close the previously used containers such as 15, and open the others. The mixed material then passes out through the inverted top of the housing. The containers may be vibrated as for example by eccentric weights 19 mounted on a rotating shaft 18 passing through the housing. More than one such shaft may be provided, and may pass vertically through the containers. The containers may be polygonal in shape.
