A compound helicopter has two counterrotating wing-mounted rotors 5 each driven by power supplied from an individual gas turbine jet engine 11 the power being transmitted through a shaft 4 and an epicyclic gear-box 6, the two gear-boxes 6, being interconnected by a transverse shaft 7 comprising two parts interconnected by a coupling which ensures synchronization of the rotors during operation as a helicopter but which can be uncoupled to enable the rotor to be moved to the fore-and-aft position for forward flight. The power may be supplied to the shaft 4 through bevel gears 18, 19 connected to the engine's turbine 16 or by a free turbine coaxial with the shaft 4 and driven by gases ducted from the engine. An auxiliary hydraulic motor may be geared to the output shaft 25 of each epicyclic gear-box 6 to enable each rotor to be rotated when the shafts 4 are de-clutched from the engine and brought to rest by hydraulic means (not shown). Each epicyclic gear-box comprises a carrier 20 driven by the shaft 4 and rotatably supporting pairs of pinions 22a, 22b meshing separately with a fixed annulus 23 and a rotating annulus 24 connected by the output shaft 25 to the rotor 5. In an alternative arrangement the fixed annulus is adapted to be unlocked and rotated to effect rotor adjustment. Low-pressure air from the engine compressor is communicated through a duct 31 and valve-controlled ports 30 into ports 29 leading to the interior of the blades to be discharged therefrom through circulation control slots.

Filed: 1973-05-29
Abstract: 1395431 Nuclear reactor coolants WESTINGHOUSE ELECTRIC CORP 29 May 1973 [15 June 1972] 25476/73 Heading G6C In a process for removing radioactive I-131 and I-125 from a nuclear reactor sodium coolant by lowering the temperature of a part of the coolant to precipitate sodium iodide and returning the purified coolant to the main stream, non-radioactive iodine is added to the coolant before its temperature is lowered. As shown, a portion of the flow of liquid sodium coolant in line 1 is passed through pipe 11 into contact with non-radioactive sodium iodide at 12. When the whole of the coolant has become saturated with sodium iodide, the by-passed stream is diverted through cold trap 16 where sodium iodide including radioactive fission product iodine is deposited on wire mesh 17. The pipe 11 may be removed as a sample tube to determine the iodine concentration.

Abstract: 666,744. Helicopters. KUSSE, F. C., and KUSSE. H. G. Oct. 4, 1949, No. 25477/49. Classes 4 and 114. A helicopter sustaining rotor comprises control means for varying the rotor blade pitch, propellers mounted on the rotor blades, power means driving the propellers to rotate the rotor, and means for varying the pitch of the propellers, the rotor pitch control means and the propeller pitch control means being interconnected. As shown, propellers 34, Fig. 2, are mounted on gear boxes 32 carried by tubular shafts 21 attached to a central rotating gear box 16. Engines mounted on the fuselage, Fig. 1 (not shown), drive the propellers 34 through bevel gears and shafts 30 within the tubes 21. The pitch of the propeller blades 41, Fig. 3, is varied by axial movement of a sleeve 43 mounted non- rotatably and coaxially with the driving shaft 39. Circumferential grooves 44 in the sleeve engage a spur wheel 46 rotating with the propeller hub 40 and geared to worm-wheels 42 on the blade roots. The rotor blades 20 are hingedly mounted on the tubes 21 and their pitch is adjusted cyclically by a spherically mounted swashplate. Change of rotor blade pitch is transmitted by rods 52, 51 to the sleeve 43 and hence results in a change of propeller blade pitch. U. S. A. Specification 1,924,192 is referred to.

Title: Improvements in or relating to the cooling of reaction mixtures
Inventor: KING RALPH WILLIAM
IPC: B01J19/00
Filed: 1959-07-24
Abstract: A process for removing heat from an exothermic polymerization reaction carried out in an inert liquid medium comprises continuously or intermittently removing reaction mixture from the reactor to an external evaporative cooler operating at a temperature and pressure lower than the temperature and pressure in the reactor and such that part of the liquid medium is vaporized, condensing the vapour from the evaporative cooler, returning the resulting liquid to the evaporative cooler and then returning the cooled reaction mixture from the evaporative cooler to the reactor.  The polymerization may be the polymerization of olefins, e.g. ethylene or propylene, in the presence of a catalyst, e.g. oxides of molybdenum, vanadium or chromium supported on an alumina or silica-alumina carrier; or catalysts formed by mixing compounds of transition metals with metals or alloys of metals of Group I, II or III of the Mendeleef Period Table, organo-metallic compounds or hydrides of Group I, II or III metals, tin or lead, or organic boron compounds.  The liquid medium may be a petroleum fraction, pentane, hexane, cyclohexane, tetrahydronaphthalene, decahydronaphthalene, benzene, xylene, isoprene, iso-octane, nonane, decane, dodecane, cyclopentane, methylcyclopentane or methylcyclohexane.

Filed: 1936-09-22
Abstract: A corrosion-resistant coating which also forms a suitable base for paints, lacquers, enamels, &c. is formed on metal surfaces containing zinc, e.g. zinc or zinc alloy articles, by treatment with a solution containing zinc dihydrogen phosphate and a soluble iron salt, preferably ferrous dihydrogen phosphate.  The iron salt may be replaced or assisted by other accelerating agents such as one or more of the soluble salts of antimony, cadmium, cobalt, copper, nickel, and silver.  The iron is preferably added in the form of a syrup prepared by dissolving iron filings in phosphoric acid, filtering, and diluting; the use of this syrup gives an excess of phosphoric acid in the bath which prevents hydrolysis of the ferrous dihydrogen phosphate and thereby eliminates excessive sludge formation. Oxidizing agents such as ferrous nitrate, sodium nitrate, zinc nitrate, the alkali bromates, and zinc bromate may be added.  The coated articles are preferably rinsed in hot water and then in a dilute solution of chromic acid, preferably a solution containing 2-4 gms. of CrO3 per gallon at a temperature of about 180 DEG  F.
