Title: Gas blast circuit breakers having at least one tubular contact
Inventor: AMALRIC JEAN
IPC: H01H33/70
Filed: 1961-07-21
Abstract: 972,710. Gas-blast switches. ETABLISSEMENTS MERLIN & GERIN (S.A.). July 21, 1961, No. 26479/61. Heading H2B. In a gas-blast switch having tubular contacts 19, 23 and stress shields 18, 29 surrounding the contacts, one of the stress shields (29) is moved nearer to the other during the blast period to obtain optimum blast conditions. The switch shown is of the kind having a chamber 11 normally filled with compressed gas and provided with exhaust blast valves 25, 34. To open the switch, compressed air is supplied through a pipe 48 to cylinders 27, 35 to open the valves 25, 34. The valve 25 is connected to the contact 23 so that both contacts 23, 19 are initially moved upwards and bring the shield 29 nearer to the fixed shield 18. Valves operated by pistons 42, vent a cylinder 16 to atmosphere so that the pressure in the chamber 11 acting on a piston 17 subsequently moves the piston 17 so that it abuts and moves the contact 19 to open the switch. After a slight delay, valves 40, 47 shut off the gas supply to the cylinders 27, 35 and vent them to atmosphere so that the blast valves 25, 34 reclose and the contact 23 and shield 29 are moved back to the position shown. The contact 19 remains in its open position until the supply of gas to the pipe 48 is shut off to permit the valves operated by the pistons 42 to return to the position shown.

Abstract: 1,116,216. Casting processes. STEWARTS & LLOYDS Ltd. 22 June, 1965 [26 June, 1964], No. 26493/64. Heading B3F. A method of casting tubes comprises the steps of causing, by gas pressure means, molten metal to rise into a tubular die 4, the lower end of which is at a lower temperature than the upper end, holding the metal in the die for sufficient time to freeze the metal to a required thickness on the wall of the die and then releasing the pressure to remove the molten core from the die thus forming a tube. The die 4 is supported in the cover member of a furnace body 1 which contains the molten metal 3. The die is preheated by means such as gas burners prior to its location in the cover member ready for the casting operation. The temperature difference between the ends of the die will depend on the metal being cast.

Abstract: 660,533. Wood cutting and working. VAN DAMME, R. C. L. Oct. 21, 1949, No. 27130/49. Class 145 (i) In machines for planing &c. pieces of wood by means of rotating cutters arranged to produce a surface which in cross section is undulating, the up-and-down movement of the cutter or cutters is produced by means operated by the movement of the piece of wood in passing through the machine, such movement usually being due to the residual force of the piece as it is discharged or delivered from a moulding machine. The piece of wood 7 entering into the machine passes over a toothed chain 6 and below the rubber-coated rollers 9, 13, mounted to exert spring pressure. The chain 6 is carried by sprocket rollers 4, 5 which are consequently rotated one of them 5 being employed to drive, through a shaft 36, a cam 35 which through a double-armed rocking lever 23 pivoted on the frame at 29 actuates the up- and-down movement of the cutters 14, 15. Adjustment means such as screws are provided to vary the positions of the cutters. Means are also provided to prevent sideways movement of the rotating cutters and intermediate means between the sprocket roller 5 and the cam 35 or rocking lever such as a gear or an intermittently acting electromagnet may be employed.

Title: Improvements in and relating to processes for the treatment of molasses fermentationsolutions

Abstract: 538,394. Distilling. U.S. INDUSTRIAL ALCOHOL CO. Oct. 4, 1939. No. 27174. Convention date, Oct. 18, 1938. [Class 32] A process for the treatment of molasses fermentation solutions, still waste or "slop," comprises the injection of the aqueous fermentation solution into a bath of heating medium consisting of a heat-stable liquid which is non- mixable with water and has a specific gravity lower than that of the non-volatile constituent of the solution or that of the solids therefrom, the temperature of the liquid being sufficiently high to flash off the high-boiling constituents with the water, leaving solids which may be readily removed from the bath. Material to be processed, which may be previously concentrated, is introduced by the pipe 4, under the surface of the heating medium 3, which may be a highboiling mineral oil, heated in the furnace 5. Solids drop to the bottom of the vessel 2 and are removed continuously by the conveyer 7. Vapours from the vessel 2 pass to a condenser 9, cooler 10 and decanting vessel 11. The upper layer, consisting of the heating medium, is returned to the still by the pipe 12, and the lower layer, consisting of water and high-boiling constituents of the charge, passes to 13. Glycerol and lactic acid may thus be flashed off from molasses fermentation solutions. Additional steam may be employed to assist in carrying off the vapours from the still.

Title: A process for the production of sparingly soluble lead compounds from lead sulphate
IPC: C01G41/00
Filed: 1924-11-14
Abstract: Lead ores, slags, sludges &c. are rendered acid with hydrochloric acid if necessary and treated with a strong solution of an alkali or alkaline earth chloride to obtain a solution of the lead.  The solution is purified from iron if necessary by oxidation for instance with air, chlorine, bromine, chlorates or nitrates, and metals such as silver are removed by treatment with granulated or spongy lead. The purified solution is treated with a salt or acid of chromium, tungsten, molybdenum, uranium, arsenic, or antimony to precipitate the corresponding lead salt. Examples describe the production of the lead solution by treating a lead oxide sludge with hydrochloric acid and saturated sodium chloride, the solution being oxidized with potassium nitrate and neutralized with calcium carbonate to precipitate the iron.  From this solution, orange chrome is obtained by addition of potassium dichromate and sodium carbonate, chrome yellow by addition of potassium dichromate, sodium carbonate and sodium sulphate, lead arsenate by addition of sodium arsenate and caustic soda, and lead antimonate by addition of potassium antimonate.  Lead chamber sludge is treated with calcium chloride solution, the mixture is oxidized with potassium chlorate, neutralized with calcium carbonate and filtered.  Excess of oxidizing agent is removed by metallic lead, and then lead molybdate is precipitated by addition of sodium molybdate.
