Abstract: 380,415. Centrifugal machines. AKTIEBOLAGET SEPARATOR, 8, Fleminggatan, Stockholm. June 16, 1932, No. 17047. Convention date, June 19, 1931. [Class 23.] In a centrifugal machine for the separation of solids from liquids, a flushing liquid is supplied through the hollow spindle 11, Fig. 1, and channels 12, to an outer chamber 7 which is formed between the outer wall 2 of the bowl and an intermediate wall 8. Openings 9 in the wall 8 permit the flushing liquid to enter the separating chamber 4 so that a static equilibrium can be maintained between the liquid to be treated and the flushing liquid. The separated liquid is discharged from the outlet 6, while the heavier matters with the solids pass through the openings 9 and travel with the flushing liquid through the passages 13 and the outlet 10. In a modification, the bowl is constructed for the separation and discharge of two liquids in addition to the solids and the flushing liquid. A number of annular furrows can be formed in the wall 8 to prevent the solids from sticking to it, and wire gauze or similar material may be placed inside the wall 8 to reduce whirling round the openings 9. In another modification, vertical or oblique channels 20, Fig. 4, are formed in front of the openings 9, so that the flushing liquid travels with a high velocity to carry the solids to the discharge outlet. To prevent eddies, an intermediate wall 22 with openings 21 is provided.

Abstract: 594,929. Winding sliver rolls. MACKIE & SONS, Ltd., J., and MACKIE, J. P. July 4, 1945, No. 17062. [Class 120 (i)] In a machine for winding rolls of sliver composed of long staple fibres such as jute and sisal, a spindle h passing through a roll c is loaded downwardly during the winding operation by transmission mechanism subjected to pneumatic pressure. As shown, the sliver roll is positioned between two side plates a, the spindle h moving vertically in slots b and the roll being supported on and driven by rollers d. Shackles k with ball-bearing centres are slipped on the ends of spindle h and connected by wire ropes m to a yoke o connected to the piston rod p of a cylinder q supplied with compressed air through pipe s. As the sliver roll increases in size, the spindle h rises uniformly against the elastic resistance of the compressed air in the ,cylinder. The pneumatic pressure may be varied during winding, to compensate for the increasing weight of the roll, by means of a valve u the control rod v of which passes between projections w on the spindle bearing. On completion of winding, the shackles are slipped off, the spindle withdrawn and the roll ejected, residual air pressure in the cylinder q and pipe s serving to return the piston and shackles to their initial positions. The rear end of cylinder q may have an opening allowing air to enter behind the piston during winding and controlling the escape of air so as to cushion the piston on the return stroke.

Title: Improvements in and relating to protective devices for x-ray apparatus
IPC: H05G1/54
Filed: 1940-12-10
Abstract: 547,030. Protective cut-out arrangements. NORTON, C. S., and NEWTON & WRIGHT, Ltd. Dec. 10, 1940, No. 17518. [Class 38 (v)] All overload device for protecting an X-ray tube is arranged to be dependent jointly on strength and duration of current, and voltage, and to cut out the tube when the input is such that the target may be heated to its melting- point. Connected to the primary circuit of the transformer supplying the tube is a transformer primary, the secondary 6 of which is in series with that 7 of a transformer supplied at constant voltage, the circuit including a switch, rectifier, smoothing condenser 9 and resistances 10, 11. A condenser 15 in series with a resistance 13 or 13a, depending on the position of switch 21, is placed across the resistances 10, 11 so as to be charged up to a voltage depending on the current and time. A further condenser 17 in series with a resistance 14 or 14a is adapted to be charged by leakage from condenser 15 to simulate the conduction and radiation of heat from the target. On the attainment of the critical voltage, a neon tube 16 breaks down and the condenser 15 discharges through a relay 19 operating contacts 20 of a timing switch to cut out the tube. Where the tube is employed for taking a series of exposures, the cooling of the target in the intervals of non-use is simulated by the condenser-charge leaking away through a resistance. The resistances 13, 13a &c. provide for two tube-ratings and regulate the charging according to the tube-current. In a modification, Fig. 2 (not shown), the arrangement is adapted for four tubes, each having four current settings, by means of a selector switch and resistances ; the winding 5 is connected to taps of an auto-transformer which is connected across the primary 4 and has an additional voltage winding ensuring adequate voltage energization of the protective arrangement in cases where the tube-voltage is unduly low.

Drawings to Specification. [Class 41.] Cobalt is electrodeposited from anode material containing cobalt and iron, by dissolving the anode in electrolyte, chemically removing the iron, and depositing cobalt from the electrolyte on the cathode, the electrochemical balance of the electrolyte being maintained by anodically dissolving a further quantity of the anode material in another cell in which the conditions are such that cobalt and iron are not deposited therein. An anode, consisting for example of copper, 10 per cent, iron 20 per cent, cobalt 65 per cent, and impurities 5 per cent is corroded in a cell with an electrolyte having an acidity reckoned as sulphuric acid, of more than three grams per litre. The cobalt and iron go into solution. This electrolyte is withdrawn, treated to withdraw iron, e.g. by an oxidizing agent and base, and the purified cobalt solution, rendered just acid is led to the cathode compartment of another cell where the cobalt is deposited. The catholyte is kept in motion, and a hydrostatic head is maintained to ensure a flow of electrolyte through the diaphragm towards the anode which is of the same composition as that in the makeup cell. Anolyte is constantly withdrawn, acidified, and passed to the first cell for enrichment.
