Title: Improvements in and relating to liquid level regulators
Inventor: DENNIS NORMAN GEORGE
IPC: G05D9/02
Filed: 1951-11-02
Abstract: 699,491. Valves. ENGLISH ELECTRIC CO., Ltd. Oct. 28, 1952 [Nov. 2, 1951], No. 25685/51. Class 135 An automatic liquid level regulator has a cylindrical balanced valve sleeve 7 operated axially by a float 1, opening the valve when the level rises in the container 9 and vice versa, the sleeve having vanes 8 impinged upon by the liquid discharged through the valve whereby the sleeve is rotated. This prevents rotational and axial static friction, e.g. in the bearings 5, 6 for the rod 4 connecting the valve to the float, and removes dirt from between the valve and its cylinder 10. The valve may be inclined or horizontal and the rod replaced by a rope or chain. The float moves in a box 2 having orifices at the bottom regulated by a sleeve 3 so that a dash-pot effect is produced, and open at the top so that overflow of the liquid on a rapid rise of level opens the valve quickly. The valve is never completely closed and is therefore always rotating.

Patent GB-412808-A (GB)
Title: Improvements in and relating to processes for removing impurities from metal particles
IPC: B22F1/145
Filed: 1933-09-20
Abstract: Surface impurities are removed from metal particles by treating the particles at an elevated temperature but below their melting point with a gaseous mixture which at the temperature employed is reducing to the oxide of the metal, oxidizing to carbon, and inert to sulphur dioxide.  The mixture is preferably a mixture of steam and hydrogen containing from 1-15 per cent of hydrogen.  The process of cleaning electrolytically deposited copper particles which may have as surface impurities sulphur compounds and carbon from the electrolytic operation and oxide from the action of the air is described.  The particles may be briquetted before cleaning, for example to form a mass having a density of about 83 per cent of that of solid copper, and a gaseous mixture of steam with less than 1 per cent by volume of hydrogen is used as the cleaning fluid at a temperature of 1000-1600 DEG  F.  The cleaning of shotted copper and nickel is also referred to and carbon monoxide may be used instead of hydrogen as the reducing component of the mixture.

Abstract: 246,079. Dehn, F. B., (Budd Manufacturing Co., E. G.). July 17, 1924. Latches, swinging, for the doors of automobiles are retracted by a lever which is pivoted on the same pivot as the latch, and which is so engaged therewith that when the door is slammed, the latch moves independently of the actuating lever. A common spring is provided for the lever and latch. The lever 42 and latch 17 are pivoted on the pin 16 mounted on stamped-up ears 41 of the base plate 10, 11. The two ends of a spring 46 coiled round the pivot maintain the latch and lever in normal position. A pair of lugs 44 on the lever engage arms of the latch to retract it when the lever is actuated. When the door is slammed, a notch 20 in the latch permits of its riding past the striking plate without actuation of the lever. In the form shown in Fig. 6, the lever engages a pin 45 on the latch, to retract it and the lever arm is so curved as to permit free movement of the pin when the door is slammed.

Title: Improvements in and relating to the oxidation of nickel
IPC: H01J5/26
Filed: 1958-08-15
Abstract: An oxide coating is formed on a nickel body by heating the body in an oxidising atmosphere to a temperature above 950 DEG C. but below the melting point of nickel, maintaining it within said temperature range until a coating of a strongly adherent oxide complex which is readily wetted by vitreous materials is formed thereon, and then cooling it in a manner to prevent further oxidation.  Specifically, the body is first de-oxidised by dipping in a solution made up of 1125 ml. HNO3, 750 ml. H2SO4, 500 ml. H2O and 6 g/l. Na Cl, or by heating in hydrogen, oxidised by heating in air, oxygen-enriched air or oxygen, and then cooled in an inert atmosphere or by quenching in e.g. water, glycerol, acetone, mineral oil, an aqueous borate solution or a bath of copper pellets.

Title: Process for the production of iron-containing organic compounds
IPC: C07F15/02
Filed: 1952-10-21
Abstract: The ferric salt of a  : g -dihydroxybutyric acid (di-a  : g -dihydroxybutyro-ferric acid) is prepared by reacting a solution of an alkaline-earth salt of a  : g -dihydroxy butyric acid, obtained by heating hydroxy-butyrolactone with a solution of an alkaline-earth hydroxide, with a ferric salt of an acid, the alkaline earth salt of which is insoluble in the solvent employed, filtering off the resulting precipitated alkaline earth salt and evaporating the filtrate in vacuo, thereby obtaining the di-a  : g -dihydroxybutyroferric acid.  The acid may be converted into its salts by neutralization with hydroxides, carbonates or bicarbonates. In an example, hydroxybutyrolactone is heated with baryta water and the resulting solution reacted with ferric sulphate, the precipitated barium sulphate filtered off, any residual sulphate ions removed with barium chloride, the filtrate evaporated to dryness and the residue precipitated from methanol solution by acetone.  The butyroferric acid is converted to its sodium salt by aqueous sodium bicarbonate. The baryta may be replaced by magnesium, calcium or strontium hydroxide.  Ferric phosphate may replace the sulphate; if ferric nitrate is employed, water containing methanol and ethanol is used as solvent.  The compounds have therapeutic properties.  Specification 592,814, [Group III], is referred to.ALSO:Therapeutic iron preparations contain the ferric salt of a : g -dihydroxybutyric acid (di-a : g -dihydroxybutyro-ferric acid) or salts thereof (see Group IV (b)).
