Title: Method for producing alkali metal oxides and peroxides
IPC: B01J19/26
Filed: 1946-07-01
Abstract: In the production of an alkali metal oxide or peroxide in a fluffy and uniformly oxidized form of low apparent density, molten alkali metal, e.g. sodium and/or potassium, is oxidized by spraying it into a current of an atmosphere containing oxygen and p  a gas inert to the metal, the atmosphere being supplied in an amount such as to provide an excess of oxygen over that theoretically necessary for the oxidation and such, relative to its temperature, as to quench the oxide below its melting point as rapidly as it is formed.  The atmosphere may be heated prior to contact with the sprayed metal to a temperature to maintain the alkali metal molten immediately prior to oxidation.  In the production of peroxides of high reactivity with exhaled air, the atmosphere, such as air, may contain from 13 to 35 per cent of oxygen and in making potassium tetroxide be supplied in an amount to provide from 5 to 15 times the oxygen theoretically required, in addition to which the air and potassium are heated to 74 DEG  C.  A spray of known type is used for spraying the molten metal in a chamber heated only by the heat liberated by the oxidation.

Abstract: 1,079,464. Controlling helicopters. UNITED AIRCRAFT CORPORATION. May 10, 1965 [May 29, 1964], No. 19672/65. Heading B7G. [Also in Division F1] A reversible-pitch control fan for a helicopter comprises impeller blades 52, Fig. 2, each connected at its root end to a member 60 pivotally mounted on the impeller hub 50 and connected by a crank and an adjustable link 84 to an arm 82. The arms 82 project froma hub 80 carried by a rod 86 which projects through the impeller hub 50 and impeller shaft 76 and is axially movable by means of a servo mechanism 150 to vary the blade pitch. At its tip end, each blade 52 has a pivot spindle 90, Figs. 3 and 5 (not shown), carrying an arm 110 which is slotted to embrace a stationary pin (116) with a small clearance which limits the pivotal movement of the spindle to a maximum of approximately 1 degree in either direction from the zero-pitch position of the blade. When the root ends of the blades are turned beyond this angle, the tip ends are restrained from further movement and the blades consequently become twisted from root to tip, the maximum pitch angle at the tips being 11 degrees. For flexibility, the blades are of flat sheet metal, of fibre glass, or constructed with aluminium ribs attached to a steel tube and covered with fibre glass. The tube may be of varying section along its length to control the variation of twist along the length. A seal ring 200 provides sealing between the peripheral rim (100) of the impeller and a stationary shroud 32. The fan is driven by a shaft 20 extending through a hollow strut 74. The blade pitch may be variable cyclically.

Abstract: 808,582. Fire extinguishing; cutting off inflammable fluids in event of fire. AEROGRAPH CO. Ltd. June 27, 1957 [June 27, 1956], No. 19959/56. Class 47 A pressurized gas pipe system is arranged to maintain supply valves in a pressurized inflammable fluid supply system open against a lesser pressure, for example spring pressure, the gas pipe system including pipe lengths of highly inflammable material at fire danger points so that an outbreak of fire destroys part of the gas pipe system, releases the pressure therein and permits the fluid supply valves to close. The invention described relates particularly to paint spray feed arrangements, in one embodiment of which a pump 16 operates a circulating system for paint, the paint supply line 17 being split up into sections by diaphragm valves 10 maintained in the "open" position by pressure in an air main 8. The air main 8 includes celluloid pipes 8a which span the spray booths 1. On outbreak of fire in a spray booth the main 8 quickly loses pressure and the valves 10 thereby close. Simultaneously the pump 16 is stopped by a stop button 19 which is normally maintained in the "on" position by pressure in an air cylinder 18 fed from the air main 8. In addition release of pressure in the air main 8 may cause operation of other safety devices, for example, a dump valve 21 for draining paint from the tank 22 to an underground tank, a CO 2  gas discharge fire extinguishing system operator 23, an operator 24 for dampers in fume ducting and operators 25 and 26 for audible or visible warnings. To prevent inadvertant operation of the valves and other safety devices on temporary failure of the air supply, an air pressure reservoir, fed through a non- return valve, may be provided. The air main is fed through a restiction orifice. In other embodiments, Figs. 1 and 2 (not shown), the paint is fed to the booths from pressurized tanks.
