Title: Separation of Water-Vapour from Natural Hydrocarbon Gas.
IPC: E21B43/01
Filed: 1967-05-17
Abstract: 1,167,058. Separation of water from natural hydrocarbon gas. MOBIL OIL CORP. 17 May, 1967 [17 May, 1966], No. 22962/67. Headings B1B, B1D and B1T. Natural gas, obtained at high pressure from wellhead 16 below the surface of a body of water e.g. the sea, flows through flowline 20 and conduit 40 into an elongated vessel 26 where the gas undergoes expansion and cooling so that a major portion of the watervapour condenses in the form of droplets Vessel 26 is below the surface of the sea, and is mounted on base 30. The condensate, including heavy hydrocarbon oils, collects in the sump of vessel 26. Before expansion, the gas from wellhead 16 flows through a hairpin tube in the lower part of vessel 26, and is then injected through a choke in conduit 20 against deflector 42 in vessel 26. The expanded gas flows through vanes 44 and across plates 46 into mist extractor section 48. The cold expanded gas, free from the major part of the water-vapour, flows via conduit 50 through looped-tubing 52 wherein the gas is warmed by heat-exchange with the surrounding sea-water. The separated oil is withdrawn from vessel 26 through conduit 56, and the water is discharged through port 58. The treated gas and the oil condensate are led to separate tanks through lines 22 and 24, respectively. By using such apparatus, there is no formation of solid hydrates in the flowlines.

Patent GB-619496-A (GB)
Title: Improvements relating to the distillation of coal tar or mineral oils
IPC: C10C1/04
Filed: 1945-09-10
Abstract: Coal tar or mineral oil is preheated to dehydration temperature and passed into a flash chamber in which all the water contained in it is flashed off as steam, the dehydrated oil is then mixed with pitch and passed, in turbulent flow, through a pipe still; the hydrocarbon vapours evolved are sent to a fractionating column, and some of the pitch obtained as residue is mixed with fresh dehydrated oil and recirculated through the pipe still.  The steam from the flash chamber does not enter the fractionating column; it is preferably used in the preheating system, after which the light oils withdrawn from the flash chamber with the steam are separated from the latter and used as reflux liquid in the column.  Coal tar, withdrawn from tank 1, is treated with soda (in order to neutralize ammonium chloride) in pipe 8 and pumped through pipe 14 to heat-exchangers 17 and 19 wherein it is heated by the steam and light oils from dehydration flash chamber 21; it is then further heated in heat-exchanger 24 which is heated by exhaust steam from the pumps. The tar is next passed through pipe 29 to trap 30, where vapours are vented, and then to heat-exchanger 31 which is heated by anthracene oil from fractionating column 32.  The tar now passes through heat-exchangers 40 and 41, which are heated by finished pitch from reservoir 48, and is then conveyed by pipe 45 to coil 47 in pipe still 7, wherein it is raised to a temperature between 150 DEG  and 180 DEG  C., the pressure being 60 to 80 lbs. per square inch.  The preheated tar passes through pipe 50 and relief valve 51 into flash chamber 21 where water and light oils vaporize and are taken off through pipe 20 to preheaters 17 and 19, condenser 53 and separator 55.  The separated oil is supplied as reflux for column 32 through pipes 57 and 103.  The dehydrated tar flows into reservoir 63 and from there it is pumped to injection chamber 65 through pipe <PICT:0619496/III/1> <PICT:0619496/III/2> <PICT:0619496/III/3> 66, the flow being controlled by level controller 68 which governs the supply of steam to pump 67.  Hot pitch, supplied through pipe 73, is injected into the tar in chamber 65, and the mixture is fed to coil 46 of pipe-still 7 where it is heated to 330 DEG -350 DEG  C. The mixture then passes through pipe 75 into flash chamber 77 where oil is vaporized and passed to column 32 through pipe 87, whilst the pitch which collects at the bottom of the chamber flows into reservoir 48.  Column 32 is heated by live steam, and the condensed "heads" are passed to separator 94 to remove water from the crude benzole: some of the latter is returned to the column as reflux.  The head temperature of column 32 is controlled by the amount of reflux supplied to it, the latter being controlled by thermostat 105, and valve 130.  The residue from the column is conveyed, via seal pot 107, to tank 110, and finally to crude tar storage tank 1. Specifications 608,301 and 619,574 are referred to.

Title: Improvements in or relating to bladed wheels for use with elastic fluids
IPC: F01D5/04
Filed: 1954-08-12
Abstract: 761,187. Elastic-fluid turbines; centrifugal compressors. GARRETT CORPORATION. Aug. 12, 1954 [Sept. 11, 1953], No. 23426/54. Classes 110 (1) and 110 (3). A bladed wheel for use with elastic fluids comprises a number of adjacent axially connected rotatable hub portions, each having extending blade portions arranged to be in direct overlapping engagement, in the direction of rotation, with blade portions of the adjacent hub portions. An inward-flow turbine rotor comprises a back-plate 11, Fig. 1, having a cylindrical extension 13 over which is fitted a similar extension 14 of a separate hub 15. Pins 21 are inserted in alternate holes 23 before assembly and are subsequently driven into alternate holes 24 by means of a tool inserted through openings 22 and the unused holes 23, 24. Slight projections (not shown) on the cylindrical surfaces of the pins 21 ensure a tight fit in the holes 23, 24. Blades 12 and 16, integral with the back-plate 11 and hub 15 respectively, abut each other at edges 17 and 18, Figs. 1 and 3, which are disposed at an angle of about 45 degrees to the plane A of rotation. The interengagement of the edges 17, 18 damps the vibration of the blades 12, 16. A thick stationary ring 28 absorbs heat from the peripheral part of the back-plate 11, while the inner part of the back-plate 11 is heated by hot working gas entering the openings 22. As a result, thermal stresses in the back-plate due to unequal heating at starting are reduced. When the flow of gas is shut off, the ring 28 radiates heat to the peripheral part of the back-plate 11 and prevents it from cooling too rapidly in comparison with the inner part of the back-plate. A labyrinth seal provided by annular ribs 12b, 12c and annular grooves 29, 30 prevents excessive flow of hot gas along the back of the backplate 11. In a modification, Fig. 6, the blades 35, 36 are offset, with their edges 44, 45 set at an acute angle to each other so as to overlap between the points 42 and 43. The invention may be applied to compressors.

Title: Improvements in or relating to dressing fish
IPC: A22C25/12
Filed: 1938-08-09
Abstract: 517,882. Dressing fish. AKTIEBOLAGET G. AREHNS MEKANISKA VERKSTAD. Aug. 9, 1938, No. 23525. Convention date, Aug. 10, 1937. [Class 28 (ii)] In the dressing of fish, e.g., decapitation or evisceration, the fish is positioned for presentation to the dressing tool by means which displaces it longitudinally to an extent determined automatically by a member which is displaced to an extent depending upon the thickness of the fish at the gills. As shown, the fishes are placed in transverse pockets 4 on a conveyer 3, the heads being supported on plates 25 on a shorter conveyer synchronised with the main conveyer 3. The fishes are moved forwardly in the pockets 4, e.g., by a water jet, until their heads hit a plate 6, or the positioning may be effected against an abutment before the fishes are dropped into the pockets so that the heads are spaced slightly from the plate 6. The fishes are moved in front of a bent plate 8 and beneath a plate 9 which is grooved, on its lower side, in the direction of movement of the conveyer. The plate 8 positions the fish for presentation to a dressing-tool, e.g., a decapitating knife 5 and is controlled by the plate 9 which, gauges the thickness of the fish at the gills. The plate 8 is secured to a lever 14 pivoted to a bracket 1 and is retracted from the conveyer to an extent determined by a stop 11 adjustable on a lever 12 pivoted on a pin 13 on the bracket. The rear end 16 of the lever is upturned and carries a pin 17 for a roller 18 which bears upon a cam surface 19 on the rear end of a lever 20 which is pivoted on a pin 21 on the bracket and carries the gauge plate 9 which is adjustable vertically thereon. A torsion spring 23 tends to depress the plate 9. In operation, cam plates 26 carried by the plates 25 engage a roller 27 adjustably secured in a slot 15 in the lever 12, the lever 12 thus being swung to allow the plate 8 to move away from the conveyer and the fish head to be positioned in front of that plate. The roller 27 then rides on the rear part of the cam 26 to allow the stop 11 to move the plate 8 towards the conveyer when the lever is so urged by the cam means 18, 19. This is effected by the plate 9 dropping, under the influence of the spring 23, on to the fish. When the plate 9 rests on the fish, the movement of the plate 8 stops. The plate 8 is arranged to move three times as fast as the plate 9. In a modification, the fish is pulled forward into the correct position for presentation to the dressing tools.

Title: Improvements in or relating to means for limiting mechanical vibrations in electrical apparatus
IPC: H01F29/12
Filed: 1962-06-20
Abstract: 1,010,692. Screw and nut gearing. BRITISH OXYGEN CO. Ltd. June 20, 1962 [July 3, 1961], No. 23717/62. Heading F2Q. To prevent the separation of mating surfaces in screw-and-nut gearing and thereby limit vibration in electrical apparatus wherein the screw-and-nut gearing effects relative displacement of parts to vary some electrical characteristic, the screw mating surfaces are inclined 15 to 50 degrees to the screw axis so as to have a wedging action and are subjected to a non-reversing axial electromagnetic force arising from operation of the apparatus. The electromagnetic force is augmented by a mechanical, such as spring, force. The thread may be of V form or, since only one flank is load-supporting, a buttress thread loaded on its "back" flank may be used. The screw-and-nut gearing may move a coil or set of coils or a stack of laminations relative to another set of coil or coils in a variable reactance transformer, such as a welding transformer, or a stack of laminations relative to a choke coil to adjust the impedance of a welding choke. In the moving coil welding transformer shown, a coil support 29 is integral with a nut 31 engaging a lead screw 10 which carries a handle 28, is mounted in a housing 27 and, to contain vibrations transmitted thereto, is adjustably, resiliently constrained in the axial direction by cup springs 17 arranged between adjusting nuts and lock nuts 23, 25 and washers 22 abutting thrust races 16. The support nut 31 has spaced threaded portions 33, 34 for stability. A helical spring 36 is interposed between the support nut 31 and an abutment nut 37. Both nuts 31, 37 are prevented from rotation by guides 38, 39 so as to maintain the same relative spacing during rotation of the lead screw 10 and thereby maintain the spring compression constant.

Title: Improvements in means for the discharge of liquid from rotors
Inventor: CSILLAG ISTVAN
IPC: H02K9/193
Filed: 1962-06-20
Abstract: 1,014,812. Dynamo-electric machine cooling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 15, 1963 [June 20, 1962], No. 23783/62. Heading H2A. [Also in Division F2] A liquid discharge arrangement from a turbine-driven electric generator rotor comprises a collecting chamber in or on the rotor receiving liquid to be discharged, ports extending outwardly from the chamber and arranged when the rotor is stationary to discharge liquid into a receiving chamber which surrounds but does not rotate with the rotor, and a Venturi nozzle disposed in one of the ports and through which the liquid flows, the throat of the Venturi being provided with a passage in communication with a source of gas, whereby when the rotor rotates gas is induced into the throat to reduce the density of the fluid flowing outwardly through the Venturi and, when the speed of the rotor is sufficiently high to produce a sub-atmospheric pressure in the collecting chamber, to permit the outward flow of liquid through the Venturi to cease and permit the Venturi to act as a gas inlet port to the collecting chamber to reduce the degree of vacuum in the collecting chamber. A cooling water discharge from a turbinedriven electric generator shaft 1 comprises ports 23 extending from an annular collecting chamber 21 in a shaft extension 3 to a stationary receiving chamber 29, Figs. 1,2. Chamber 29 has a labyrinth seal 27 and a drain pipe 31. Two ports 23 have Venturi nozzles 33, Fig. 3, each formed within a bolt 33A screwed into the port 23 and within a head screwed on to the bolt 33A. Grooves 37 and 39 in the bolt 33A and head respectively form passages communicating with atmosphere and with the throat of the Venturi 33. In operation, cooling water is pumped through the bores 7 and 5 in the direction 9 and returns in direction 19 to chamber 21. When the machine is stationary water flows through all the ports 23 to chamber 29, but when rotation occurs air is induced from the periphery of the shaft 3 through passages 37, 39 to the Venturi throat. The air mixes with the water in flowing outwardly through the Venturi 33 and at high speeds the Venturi ceases to discharge water, though water continues to flow through the remaining ports 23. The construction reduces cavitation in chamber 21 and cooling passages of the shafts.
