Title: Improvements relating to conveyors
Inventor: LOW ALEXANDER CHARLES
IPC: B65G23/44
Filed: 1956-12-01
Abstract: 845,890. Endless conveyers. MAVOR & COULSON Ltd. Dec. 2, 1957 [Dec. 1, 1956], No. 36804/56. Class 78 (1). In an endless scraper conveyer of the kind having a sectional framework, the end section at one or both ends of the conveyer is mounted for longitudinal sliding relatively to the adjacent section and is provided with a pair of hydraulic rams 36 connected between these two sections, the rams 36 being supplied with fluid by a hand pump 31 to move the sections apart and thereby increase the tension in the scraper chains, and a valve 33 being provided for releasing fluid from the rams to reduce the tension in the scraper chains. The end section comprises side walls 16, 17 and a conveying floor 18, these parts telescoping within the corresponding parts 10, 11, 12 of the adjacent section. The side walls 16, 17 of the end section are provided with ribs 25 which are slidable longitudinally on girders 26 secured to the adjacent section and which house the rams 36. The cylinders of rams 36 are secured to the girders 26 and the piston-rods 37 are secured to brackets 43 on the end-section. Upon operation of pump 31, fluid is delivered from a reservoir 30 to the valve 33 which may be adjusted to three positions. In one position, the fluid is passed via pipe 38, and branch-pipes 38a, 38a, to one end of each ram cylinder to cause the endsection to move away from the adjacent section so as to tension the conveyer chains. Displaced fluid from the other ends of the ram cylinders is passed via valve 33 and pipe 34 to reservoir 30. In the second position, the ram cylinders are isolated to maintain the tension in the conveyer chains. In the third position, fluid is allowed to flow back through the pipes 38a, 38a and 38, the valve 33 and pipe 34 to reservoir 30, this operation being facilitated if necessary by operating the pump to supply fluid via pipes 39, 39a, 39a to the other ends of the ram cylinders so that the end section moves towards the adjacent section to reduce the tension in the conveyer chains. A gauge 50 (Fig. 1, not shown) is fitted to the pipe 38 to indicate the tension in the conveyer chains. The end section includes a driving- drum 13 having chain sprockets 14, 15, the drum being driven by either a single motor 23 through gear-box 24, as shown, or alternatively by two motors disposed on opposite sides of the conveyer driving through separate gear-boxes 24, 24a.

A plate 16, e.g., sintered or having many small holes, supports the bed whilst allowing the fluid to pass therethrough. A membrane (30) (Fig. 2F, not shown) having a central hole to receive the workpiece, may be placed over the top of the bed to assist the build up of a vacuum to clamp the workpiece. Alternatively the top layer of the particles may be of a smaller size than the rest, to fill in the spaces between the larger particles when a vacuum is applied through passage 12. Various configurations of particles are described (Figs. 2A-2F, not shown), and they may be coated with a resilient material to prevent marking a workpiece and to assist in locking together during clamping. An arrangement is described (Fig. 4, not shown) of a matrix of separate clamps connected through control pipes to a computer control means for automatic programme controlling of the workpiece clamping.

Title: Improvements relating to the recovery of nickel from sulphide ores
Inventor: QUENEAU PAUL ETIENNE
IPC: C22B5/20
Filed: 1955-12-28
Abstract: In a process for extracting nickel and iron, and cobalt if present, as carbonyls from a sulphidic nickel-bearing ore, the preparation of the feed to the volatilizer in which the carbonyls are formed includes concentration of the ore, with, or without, subsequent smelting, to produce a concentrate or matte in which the weight ratio Fe:Ni is less than 10:1, roasting to reduce the S content to 2% or less, and reducing the roasted material with reducing gas to produce a metal-containing product which on treatment with CO yields a mixture of volatilized nickel and iron carbonyls in which the ratio of Fe:Ni is 2:1 to 1:7 and the treatment in the volatilizer is effected under pressure in the presence of active sulphur.  The ore is subjected to beneficiation, by froth flotation and magnetic separation, to form a concentrate in which the ratio Cu:Ni is not more than 1:10.  The concentrate may be smelted to a matte containing say 10% or more Fe and dead-roasted.  The roasted product is reduced at 1300-1600 DEG C. in a controlled atmosphere to convert a maximum proportion of Ni and Co and a controlled proportion of Fe to metal. The controlled atmosphere may be obtained by partial combustion of fuels, e.g. coal, oil, or natural gas, containing CO:CO2 in the volume ratio 3:2 to 1:3, which may be wholly or partially replaced by H2 and H2O in equivalent ratio, or H2 alone.  The reduced product is cooled to between 60 and 32 DEG C., and treated with H2S to absorb not more than 1% S.  Alternatively, active S may be introduced as in Specification 347,208 before, during, or after reduction, or during volatilization.  The product is reacted with CO at between 350 and 1000 p.s.i.g. and 175 and 350 DEG F., and the mixed carbonyls of Fe, Co, and Ni are condensed and separated.  Separation may be effected by cooling to crystallise cobalt carbonyl and fractionally distilling and fractionally distilling nickel and iron carbonyls, or by fractionally distilling off nickel and iron carbonyls and isolating cobalt carbonyl from the residue.  The carbonyls may be decomposed to metal and the residue from the volatilization may be leached, or smelted to a matte, bessemerised, and refined to isolate copper or precious metals.

Title: Improvements in and relating to systems for producing alternating current.
IPC: H02J3/08
Filed: 1967-08-14
Abstract: 1,166,197. Standby supply systems. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. 14 Aug., 1967 [3 Sept., 1966], No. 37265/67. Addition to 1,166,196. Heading H2H. In a system as disclosed in the parent Specification for producing alternating current of substantially constant frequency from a variable speed source wherein a synchronous machine 10 driven from the source 13 feeds a load bus-bar 16 through an uncontrolled rectifier 14 and a controlled bridge inverter 15, with a synchronous condenser 17 normally supplying reactive current, a means is provided for controlling the firing of the inverter elements responsive to the commutation voltage and a reference signal so that the firing instants occur when the commutation voltage is below the reference value. The reference voltage preferably has a sawtooth shape but it may be sinusoidal, and the firing angle should lie within the range 90- 180 degrees of each supply wave. After temporary short-circuit conditions across the busbars, the ignition voltage is made ineffective for a predetermined time. Such short-circuit currents, as measured by a unit 83, may also be fed through a threshold device 84 to a comparator 85 causing weakening of the machine 10 excitation. The excitation is normally controlled by comparison of a signal Xa representative of a frequency or other parameter with a corresponding reference Xr. The inverter may include rectifier elements of the thermionic valve or semi-conductor type, which may be series or parallel connected. The power for the ignition circuit may be derived from a pair of parallel connected rectifiers (77), (78), Fig. 3 (not shown), one fed from the bus-bar 16 and the other from a current transformer in series with condenser 17. The ignition voltage may be derived across the controlled rectifier elements through a Zener diode to ensure constancy. A number of alternative arrangements are described in the Specification including one to start in sequence a plurality of synchronous condensers from the bus-bar 16 through a common choke (116), see Fig. 8, not shown.
