Title: Method of Chlorinating Titanium-Bearing Materials
IPC: C22B34/12
Filed: 1968-11-22
Abstract: 1,191,767. Chlorinating titanium bearing materials. PPG INDUSTRIES Inc. 22 Nov., 1968 [7 Dec., 1967], No. 55506/68. Heading C1A. Titanium tetrachloride is prepared by chlorinating a titanium-bearing material in a fluidized bed, in the presence of a carbonaceous reductant and a metal source selected from magnesium, calcium, strontium, barium, cadmium and mixtures thereof. Amounts may be sufficient to increase the ratio of CO 2  to CO, both of which are produced during the reaction, but less than an agglutinating amount. Any fluidizable source of titanium is suitable for this process, especially a source containing in excess of 90% by weight of titanium dioxide. Rutile, especially Sierra Leone rutile, is particularly suitable for treatment. Particle size may be between 75 and 500 Á. The reductant may be coke, carbon monoxide, graphite, charcoal, carbon tetrachloride or phosgene. Carbon content may be 10-50% by weight of the total composition of the bed. The average particle size of the reductant may be between 100 and 900 Á. The temperature of the reaction is preferably above 500‹ C. The additives may be introduced as carbonates, sulphates, chlorides, oxides, phosphates, carbides or as the free metal. They may also be introduced in a second titanium-bearing material, provided that this material contains more of the additive than is present in the original titanium source. For example, Australian rutile may be added to Sierra-Leone rutile as a source of calcium and magnesium. The amount of additive may be between 0À001 and 0À35 weight per cent, based on the amount of titanium dioxide in the titanium-bearing material.

Title: A device suitable for charging a storage battery from an alternating power source
IPC: H02J7/02
Filed: 1968-12-04
Abstract: 1,245,825. Battery-charging systems. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION. 4 Dec., 1968 [6 Dec., 1967], No. 57697/68. Heading H2H. Battery-charging circuit comprises an A.C. source, an impedance which limits the charging current, and a controlled rectifier, the firing angle of which is regulated in accordance with the battery voltage. In the circuit shown in Fig. 1, the battery B is charged from a mains transformer Tr by way of a limiting inductance L1, a rectifier bridge Rd, and a thyristor Th. The firing of the thyristor is controlled by a synchronized power supply system comprising transistors T10 and T11, and a pulse generator including transistors T2 and T3 and a capacitor C1 The emitter of transistor T10 is held at a fixed voltage derived from a secondary winding S<SP>1</SP> of the transformer Tr, and when the output of the bridge Rd reaches a preset value each half-cycle, the transistor T10 is biased on and in turn switches on the transistor T11. This applies a steady voltage to the transistor T2 which charges up capacitor C1 until a unijunction transistor T1 breaks down, whereupon the capacitor discharges and applies a firing pulse to the gate of thyristor Th. A train of such pulses will be supplied during the period that transistors T10, T11 are conducting. The firing angle of the thyristor, i.e. the delay before the arrival of the first pulse, is determined by the rate of charging of capacitor C1, controlled in turn by the biasing of transistors T2 and T3. A voltage representative of the battery voltage is derived from a potential divider R8-R12, and this is compared with a reference voltage from a Zener diode Dz3 by transistor T3 in such a way that the firing delay varies inversely with the battery voltage. Temperature dependent resistors CTN, CTP, having respectively negative and positive temperature coefficients, regulate the charging current according to the battery temperature. Auxiliary devices, Figs. 3 and 4 (not shown), may be connected to the circuit of Fig. 1, and comprise means for automatically charging the battery more rapidly after mains failure. During any period of such failure, a secondary accumulator is charged by the battery B, and its subsequent discharge raises the main charging rate. A further device for increasing the charging rate when the battery voltage has dropped substantially due to heavy loading may also be connected.

Abstract: 1367479 Convection circulation steam generator; tube walls for furnaces FOSTER WHEELER CORP 14 Dec 1971 [14 Dec 1970] 58034/71 Headings F4A and F4B A convection circulation steam generator comprises a rectangular furnace enclosure 12 having radiantly heated front and rear walls 14, 16 and side walls 18 formed from welded finned water tubes 68 which are increased in diameter, see Fig. 3, in the region of burners 70 formed in the walls of the furnace. The smaller diameter section of the water tubes gives relatively high flow for better cooling in the region E of the burners 70 and the tubes can be made small enough to permit the use of plain carbon steel tubing. The larger diameter tubing increases the surface area of heat absorption for a given periphery in the upper region. The hot furnace gases pass through an exit C to pass down a convection area D containing a superheater 40, an economizer 42, and a reheater 38. An inwardly projecting section 24 of the furnace walls diverts gases against tube panels 46 which are connected in the flow circuit upstream of further superheater tubes 48. The tubes 46, 48 cool the gases at the exit to within design limits.

Preferably the movement of the arm is such that it passes the discharge zone in each direction of its movement. The arm may, when seen in plan, be a sector of a circle pivoting about the axis of the circle and with an angular extent not greater than 280‹, preferably 150‹. However the arm may be a blade 23 pivotable through an arc of between 320‹ to 360‹ with the movement of the blade always terminating over the discharge zone. Cutting tools may be provided along the length of the arm. When the arm is a sector of a circle then a stationary blade may be located immediately above the path of movement of the arm to sweep it clear. The discharge zone may be a recess 21 in the rearward edge of the ramp and a chute may be provided to lead spoil from the recess to the conveyer. The oscillatory motion of the arm may be caused by a double acting hydraulic ram.
