Title: Temperature regulating system
IPC: G01K11/06
Filed: 1928-02-18
Abstract: 285,499. Selden Co., (Assignees of Andrews, C. E.). Feb. 19, 1927, [Convention date]. Hydrocarbons, cracking and distilling. - The invention relates to devices for regulating temperature (particularly in catalytic converters) of the kind comprising a two-phase liquid-vapour system containing a plurality of ingredients of which at least one is solid at ordinary temperatures, and provided with reflux condensing means; it consists in varying the boiling-point of the system by altering the composition of the amount of the reflux condensate before returning it to the liquid phase of the system. For example, in the case of a mercury-cadmium alloy, a part of the condensed mercury vapour may be withdrawn from circulation, or the reflux condensate may be diluted with more mercury or enriched by allowing it to impinge on and dissolve a mass of cadmium. Fig. 5 shows an apparatus for cracking oils comprising a cracking coil 44 immersed in a bath 43 the vapours from which are condensed in a reflux condenser 7, discharging into a reservoir 30, and the temperature of the bath is maintained constant bv adding or withdrawing part of the contents of the system at points 37, 32 or by adding cadmium from the hopper 35.

Abstract: 1,093,022. Resolver circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. Feb. 2, 1965 [Feb. 7, 1964], No. 5247/64. Heading G4G. [Also in Division G1] In a positional control system for rotating a member through an angle (A+B) where A is the coarse value of the angle and B the fine value, the values cos A and sin A are first obtained from a tapped autotransformer 2 (Fig. 1) by rotation of ganged switches 3, 4, and these values are fed to quadrature stator windings 19, 20 (Fig. 2) of a resolver with quadrature rotor windings 21, 22. The voltage in winding 21 is fed to a further tapped autotransformer 23 whose slider is set to tan B, and the resultant voltage is compared with that in winding 22. Any difference energizes a motor 18 which rotates the resolver rotor windings until the difference is zero. It is shown that the angle through which it rotates is equal to (A+B). An alternative method, stated to be prior art, is to use a resolver 15 (Fig. 1) with a single rotor winding 16, feeding the stator windings 13, 14 with voltages Vs, Vc respectively where Vs sin A + Vc tan B and Vc = cos A - Vs tan B, and driving rotor winding 16 to its null position, when its angular rotation is the angle (A+B).

Title: Method of lubricating metal surfaces
IPC: F16N17/02
Filed: 1959-02-16
Abstract: Metal surfaces at elevated temperatures, particularly gas turbine engine bearings, are lubricated by contacting the surfaces with a blend of air and a vaporized polyoxyalkylene fluid having a viscosity of 40-260 S.U.S. at 38 DEG C., the weight ratio of air to polyoxyalkylene fluid in the blend being from 4:1 to 13:1. Instead of air, another free-oxygencontaining gas may be employed, provided it is used in such a proportion that the weight ratio of free oxygen to polyoxyalkylene fluid is equivalent to that in the air-polyoxyalkylene fluid blend mentioned above.  The polyoxyalkylene fluid is a polyoxyalkylene glycol or a mono- or di-ether or ester thereof of formula R1O(R2O)nR3 wherein R2 is an alkylen radicle, R1 and R3 are hydrogen or hydrocarbon or acyl radicles and n is an integer greater than 1.  The lubrication of the metallic surfaces with the vaporous mixture is improved by forming a protective film on the surfaces by applying thereto a substance containing a sulphur, selenium, tellurium, phosphorus or halogen atom.  The surfaces may be pretreated or a substance may be incorporated in the vaporous lubricant so that, for example, a sulphide, selenide, telluride, phosphate, phosphide or halide film is formed on the metallic surfaces.  Substances which are readily used in the vaporous state include sulphur, hydrogen sulphide, carbon disulphide and chlorine. Alternatively the surfaces may be pretreated by lubricating at about 400 DEG F. with sulphurized mineral oil.  A preferred method of forming the protective film is to utilize an organic ester of phosphorus or an organic sulphide or a mixture thereof in the vaporous lubricant blend.  In examples, a bearing is lubricated at 540 DEG C. with a blend of air and vaporized ethylene oxide/propylene oxide copolymer, with or without triisopropyl phosphite (which may be used with or without dibenzyl disulphide).  For comparison purposes, the lubrication of the bearing with a blend of air and vaporized JP-4 fuel, with or without CS2 or CCl4 is also described.  Specifications 651,712 and 739,266 are referred to.

Title: Improvements relating to marine propulsion units
Inventor: HASSAN WALTER THOMAS FREDERICK
IPC: B63H11/00
Filed: 1960-02-15
Abstract: 902,049. Cooling systems for engines. COVENTRY CLIMAX ENGINES Ltd. March 6, 1961 [Feb. 15, 1960], No. 5335/60. Class 64 (3). [Also in Group XXXIII] In a marine propulsion unit in which a pump driven by reciprocating internal-combustion engine propels the craft by expelling a jet of water through an outlet, the pump is mounted below the engine crank-shaft and a part of its casing forms part of the casing of an oil sump and also includes a jacket in communication with a cooling water circuit of the engine. Thus the water pumped to propel the craft cools the oil and coolant of the engine. The pump 2 in the form shown is of the axial flow turbine type and has an inlet 7 and outlet 9. The engine 1 drives a crank-shaft 11 which carries a gear 12. A chain 13 transmits the crank-shaft drive to a gear 14 which is connected to the end of a pump driving shaft 15 by a Centrifugal clutch 30. The engine thus rotates the impeller blades 19 of the pump. The water flowing through the pump cools the oil in the sump 22 and the engine coolant circulating through the jacket 23. In a modification, Fig. 6 (not shown), two engines are disposed above the pump and have a common water cooling system. Either or both may be used to drive the pump.

Title: Means for automatically sealing valves and other closure surfaces
IPC: F16K3/36
Filed: 1957-02-18
Abstract: 833,015. Stuffing-box substitutes. VOLPIN, A. S. Feb. 18, 1957, No. 5466/57. Classes 122 (3) and 122 (5). [Also in Groups XVIII and XXIX] A sealing means in the form of a fitting 32, Fig. 2, adapted for attachment to a casing of a device containing fluid under pressure comprises a housing 33 having a piston 50 movable within a sealing-fluid reservoir 48 in response to the pressure of the fluid in the device acting on one side of the piston and thereby forcing sealing fluid on the other side to the surfaces to be sealed. As applied to a vertically-sliding gate valve, the gate is sealed, when closed against its seating, by a separate fitting 32 screw-threaded into a socket 27 in the valve casing 10 and sealed therein by conical surfaces 30, 35 and seal ring 37. A tubular casing 40, which is mounted in the fitting and retained therein by a screwed plug 51, is arranged to constitute the reservoir 48 which is closed at its inner side by the piston 50. In operation, any leakage of pressure fluid between the gate and its seating, when the valve is closed, passes into the valve chamber and thence through ports 31, 38 in the chamber casing and fitting 32 into the casing 40 for action upon the piston 50. Fluid is thereby forced from the reservoir through a port 54 around the outside of the casing 40, and through a port 46 and channel 47 into a passage 25 leading to a sealing groove 24 arranged around the valve seating. A sealant injection nozzle 53 is provided in the plug 51. For sealing the joint surfaces between the closure of a pressure vessel and its seating, the fitting 32 may be arranged in a socket in the closure so that the sealant fluid in the reservoir is forced to the joint surfaces, and if desired, the fitting may be of the modified form shown in Fig. 5 in which the inner tubular casing 67 containing the reservoir 68 seats at its lower end a socket 66 in the closure 60 and an annular space 73 surrounding the casing communicates with the joint surfaces through a lateral passage 74. In a further modification for sealing the joint surfaces between the closure 60, Fig. 6, of a pressure vessel and its seating, the inner casing 67a constituting the reservoir 68a, is held in a socket 66a in the underside of the closure and communicates as shown with the joint surfaces and interior of the vessel. Specifications 718,324 and 719,001 are referred to.
