Title: Improvements in and relating to vacuum pumps
IPC: F04C27/02
Filed: 1931-09-07
Abstract: 389,087. Rotary pumps. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and WHITAKER, F. P., 237, Clifton Road, Rugby. Sept. 7, 1931, No. 25085. [Class 110 (ii).] In a rotary vacuum pump 2 sealed by a film of oil, a shut-off valve is operated by means of vacuum, or the pressure below atmospheric, produced by the pump. The suction may be produced by a separate pump, operated by the shaft driving the main-pump. A rotary valve 10 remains open, as in the Figure, by frictional means produced by the rotation of the pump shaft so that suction first acts through a passage 3 to open the inlet valve 7, and secondly through a passage 6 to exhaust the air in the latter to a delivery 4. A slide valve 12 secures this alternation of suction. When the pump stops, atmospheric pressure and a spring or weight closes the valve 7, and oil for sealing purposes is allowed to creep into the pump. The valve 10 may be operated electrically.

Abstract: 713,929. Dry plate rectifiers. STANDARD TELEPHONES & CABLES, Ltd. Oct. 10, 1952, [Dec. 14, 1951.] No. 25435/52. Drawings to Specification. Class 37. A selenium rectifier comprises a compound of nickel selenide at the interface between adjacent layers of selenium and nickel, which is produced by heating the layers to a temperature of at least 400‹C. The base electrode may consist of iron, aluminium, magnesium, beryllium or alloys thereof, which is nickel plated and then roughened by sand blasting or etching. The selenium layer may be added by rubbing a stick of selenium across the surface, or spreading powder or pellets on the heated surface, or by vaporization. During the heating process at 400‹C. to form the nickel selenide, the electrode may be spun to remove surplus selenium, but this is not necessary if the selenium is in a finely divided state sufficient to pass through a 200 mesh screen. A second coating of finely divided amorphous selenium may then be applied which may include other material such as the halides of selenium. The coated electrode may then be subjected to annealing heat treatment at about 220‹C., which converts the amorphous selenium to the crystalline state. A laquer barrier layer is applied, followed by a counter electrode of a cadmium-bismuth eutectic alloy. The device may be subjected to electroforming. Specification 591,412 is referred to.

Patent GB-664023-A (GB)
Title: Improved method of dehydrating sodium hydroxide solutions
IPC: C01D1/42
Filed: 1949-10-11
Abstract: Aqueous sodium hydroxide solution preconcentrated below 150 DEG C and containing about 50-75 per cent solids is further concentrated by adding sucrose and evaporating at progressively increasing temperatures above 150 DEG C in contact with nickel surfaces.  The sucrose reduces any sodium chlorate in the sodium hydroxide to sodium chloride and also reacts with any oxygen in the evaporator whereby corrosion of the nickel surfaces is inhibited.  A 50 per cent aqueous NaOH solution is concentrated in a vacuum evaporator 2 at 2811 of Hg. to a 70 per cent solution which is fed at 115 DEG C to a storage tank 7 where it <PICT:0664023/III/1> is held at 100 DEG C and fed with aqueous sugar solution from a supply tank 8.  The 70 per cent liquor is then fed to an evaporator 11 which is a continuous single-pass vertical tubular heat-exchanger wherein the tubes and other parts in contact with the liquor are of nickel.  The evaporator 11 is heated with "Dowtherm" (R.T.M.) circulated via pipes 13 and 14 and operates at 2011 of Hg. at the top.  An entrained mixture of molten NaOH and water vapour at about 370 DEG C. is discharged via pipe 15 to a separator 16.  In modifications the sugar is fed to the evaporator 2 and a small flow of inert gas, e.g. nitrogen or natural gas, is fed into the bottom of the evaporator 11 to prevent "bumping" of the liquid in the tubes.
