Title: Improvements in or relating to conveyors
Inventor: WALKER JOHN ROLAND
IPC: B65G17/02

Abstract: 813,210. Endless belt conveyers; pulley mountings. CABLE BELT Ltd. Nov. 6, 1957 [Dec. 3, 1956], No. 36905/56. Classes 78 (1) and 78 (5). In a belt conveyer of the kind in which the belt 19 is supported on both upper and lower runs by a pair of endless driving cables 18 which engage grooves in the lateral edge portions of the belt and which are supported at intervals along the conveyer by pulleys, the pulleys supporting the central portions of the cables are themselves supported on fixed cables extending along both sides of the conveyer. In one embodiment, Figs. 3-5, two pairs of fixed cables 24, 25 are arranged at different levels to support respectively pulleys 34 for the upper run of the cable 18 and pulleys 38 for the lower run of the cable 18. The cables 24, 25 are secured at their ends to stanchions 26 and are supported at intervals on stands 27 each of which consists of a strutted upright 29 on each side the conveyer carrying brackets 31, 32 having arcuate longitudinal grooves in which the cables 24, 25 respectively rest. The pulleys 34 are located in the spaces between adjacent stands 27 while the pulleys 38 are located in alternate spaces between the stands. The pulleys 34 are mounted on shafts 33 and the pulleys 38 are mounted on shafts 37. The shafts 33, 37 are respectively secured to the cables 24, 25 by pairs of U-bolts 35, the U-bolts of each pair being arranged on opposite sides of the associated cable and engaging in a clamping plate 36 which clamps the cable 24 between notches in the plate 36 and the shaft 33 or 37. Turnbuckles 39 are interposed between the cables and the stanchions 26 and between successive lengths of the cables. Conventional pulleys 22 mounted on stands 23 are used to support the driving cables 18 near the reversal-points of the conveyer. In a second embodiment, Fig. 8, the fixed cables 24, 25 are replaced on each side of the conveyer by a single cable 44 which supports both upper and lower cable run supporting pulleys 45, 46 by means of brackets 49 having slots 52 and 53 to receive the shafts 47, 48 carrying the pulleys, the shafts 47, 48 having circumferential grooves to engage these slots. The brackets 49 are secured to the cables 44 by clamping plates 51.

Title: Water purification
Inventor: LITT PETER STANLEY
Filed: 1962-10-05
Abstract: <FORM:1024704/C1/1> Water containing dissolved ionic materials is purified by contact with a moving capillary lattice of matted filamentary inert dielectric material which moves in such a direction and at such a rate to prevent the ionic particles from passing out with the purified water.  Specifically exemplified are (a) a rotating drum, Fig. 1, in which the ion front 61 is separated from the purified water at the bottom by the movement to position 61a where under applied vacuum, residual water flushes the ions into a waste receiver 31a; (b) Fig. 3 in which water is purified by downward passage through an ascending wick 76, whilst ions are washed off the wick to waste at 10 and the wick purged of residual water at 82; (c) Fig. 4.  Here the impure water is fed into a jacket surrounding a rotating fibrous lattice 150 and sufficient back pressure is created by outlet 168 to just balance the centrifugal effect of the rotating lattice, whereby pure water diffuses inwards and the impurities are washed from the outer surface by the descending impure water. <PICT:1024704/C1/1>

Title: Improvements in or relating to automatic steering apparatus for vessels, vehicles and other guided bodies
Inventor: ROBERTSON THORLIEF
IPC: F41G7/24
Filed: 1954-12-31
Abstract: 806,302. Automatic steering control systems. ROBERTSON Ltd., H. Dec. 31, 1954, No. 37871/54. Drawings to Specification. Class 38(4). In a system for automatically steering a body, displacement of the body relative to a predetermined datum is detected by movement of a first member relative to a second member fixed to the body, and the variation of inductive coupling between an oscillatory circuit mounted on the first member and an electric signal generator fixed relative to the second member serves to effect automatic steering correction. In the arrangement described an oscillatory circuit comprising inductance, capacity and resistance is mounted on the card of a magnetic compass. The inductance is coupled through a further inductance mounted on the compass bowl to a Meissner valve oscillator the output of which is rectified and utilized to energize a thermionic valve relay so that variations of oscillator output in a sense corresponding to that of course deviation of a vessel cause operation of a steering engine in the appropriate sense to correct the course. Application to altitude control of an aircraft is referred to. Specification 482,189 is referred to.

The bed of a fluidized bed heat exchanger is formed of particles of common salt. The heat exchanger is intended for use in vulcanizing rubber compositions passed through the fluidized bed, which is maintained at a temperature between 100‹ and 250‹ C., the salt particles being between 50 and 200 microns in size. The container for the bed may be a horizontal trough with a base of porous tile, of sintered stainless steel or ceramic material, or other porous means which support the bed of salt and allow the fluidizing gas to rise through the base. Alternatively, the gas may be supplied through porous cylinders immersed in the salt. Another form of container comprises a vertical column made up of two or more cylindrical sections spaced by rings of porous material through which the gas may be introduced. The bed may be heated by electrical heating elements in or surrounding the bed, or may be heated or cooled by a fluid flowing in pipe coils in the bed, or preheating or cooling the fluidizing gas. The gas may be air, an inert gas, or a reactive gas-e.g. sulphur dioxide in a vulcanizing process. When sheet material is treated, rollers may be buried in the fluidized bed.

Title: Purifying electric induction lamp targets
IPC: C01B31/30
Filed: 1956-12-21
Abstract: Metal carbide targets for electric induction lamps are purified by heating in a hydrocarbon atmosphere to a temperature below its meltingpoint but sufficient to produce smoke and thereafter heated to a temperature between 3400 DEG  and 3700 DEG  K. in an inert atmosphere or in vacuo.  Preferably the target comprises a piece of tantalum carbide, although other highly refractory materials such as niobium carbide and hafnium carbide can be used.  In an example a target of commercially available tantalum carbide is heated inductively in a bell jar in an atmosphere of 50% methane and 50% of an inert diluent gas, such as argon, neon, helium or the like, at a pressure of about 1200 m.m. of mercury.  The proportion of methane may, however, be varied from about 25 to 100%.  A cloud of smoke indicates the carburization of the target material, this being effected at a temperature above 3000 DEG  K. but below the melting-point of the carbide.  Heating is continued for about ten minutes.  The target is then subjected to a further inductive heating to a temperature in excess of 3400 DEG  K. but below the melting-point of the carbide, the heating being effected in a bell jar.  The bell jar may be filled with argon at a pressure of about 1200 mm. of mercury.  Alternatively the heating may take place in a vacuum, e.g. as low as 5 microns of mercury.  The second heating drives off any excess carbon that may have remained on the target and thereby prevents subsequent blackening of the lamp.

The catalyst is placed in or on the battery 9. In a further embodiment, the temperature rise of the catalyst may be compared with the temperature rise of a resistor carrying the current being passed through the battery.
