Title: Wax crystal growth control in oil dewaxing plants
IPC: C10G73/34
Filed: 1974-05-01
Abstract: 1455597 Wax crystal growth control FOSTER WHEELER CORP 1 May 1974 [25 May 1973] 19031/74 Heading BIG [Also in Division C5] The rate of wax crystal growth in an oil dewaxer having cooled pipes through which the oil flows and in which scrapers are rotated to remove the wax, is controlled to assure efficient filter operation downstream. The scrapers are rotated at a comparatively slow rotational speed for a given period of time to provide for optimum growth of wax crystals and then automatically rotated at a higher speed to clean the interior of the pipe so that wax can continue to crystallise. Suitable apparatus comprises a dewaxing unit in which oil containing amorphous wax and solvent flows through the inner of two coaxial pipes with a coolant flowing in the annular space between the inner and outer pipes so that wax crystallises on the inside surface of the inner pipe and is removed by a scraper, moving over and bearing against the inside surface, and provided with a speed control comprising a hydraulic motor connected to feed hydraulic fluid by two lines in one of which there is a motor speed control valve connected to an automatic timer which closes the valve for a predetermined time and allows the motor to run at a slow speed, or opens the valve for a predetermined time and allows the motor to run at a faster speed sufficient to clean the inner surface of the inner pipe. Preferred speeds are 2 and 20 rpm.

Abstract: 995,332. Glove boxes. COMMISSARIAT A L'ENERGIE ATOMIQUE. May 14, 1963 [May 14, 1962], No. 19037/63. Heading B4Q. In a system for transferring parts into a glove box, the glove box has an aperture 1 in its lower wall provided with a bushing 2 closed by interior and exterior covers 3, 4, the cover 3 carrying a pressure equalizing valve 63 and the bushing 2 being sealed by a sheath 65 located in a groove 62<SP>1</SP>, Fig. 4. The part 70 to be transferred is placed in a tank 5 sealed by a cover 6 clamped against a box flange 7, with the interposition of a gasket, by a lever 56. The tank 5 is carried by a carriage 11 running on wheels 13 guided by tracks (Fig. 2, not shown), the tank being mounted for vertical movement by means of two diametrically opposite screwed rods 35 rotatable in bearings 36, 37 secured to the carriage. Each rod 35 makes threaded engagement with the ends 27, 28 of a sleeve 26 slidable in a pair of lugs 24, 25 secured to the tank but held against rotation by a key 30. A spring 31 is disposed between the lug 25 and a collar 33 secured to the sleeve 26. The rods 35 are rotated by a motor through gear-wheels 38 and a chain (not shown) whereby a lifting force may be applied to the tank 5 through the springs 31. The tank is additionally sealed by a sheath 64 located in a groove 61<SP>1</SP>. In operation, the carriage 11 is moved along the track until it abuts a stop 16, in which position the carriage is beneath the aperture 1 and is locked by a jack 20. The covers 4, 6 are removed and the sheaths 64, 65 are slid into grooves 61, 62 and a flexible sleeve 66 is fixed in the grooves 61<SP>1</SP>, 62 1 , Fig. 5. The sheaths 64, 65 are then removed and the gear-wheels 38 are driven to lift the tank 5 so that a gasket in a groove 44 at the top end of the tank seals with the bushing 2. The amount of upward movement of the box is limited by a micro-switch operated by the tank movement (Fig. 3, not shown). A lifting device (not shown) within the glove box removes the cover 3 and then lifts the part 70 to be transferred from the tank.

Abstract: 395,873. Converting; phase-changing. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. July 8, 1932, No. 19339. Convention date, July 11, 1931. [Class 38 (ii).] The control voltages for a discharge device, having grids energized by flash-over, are obtained from a transformer with a large voltage step-up, the primary windings of which are connected in the anode circuits of an auxiliary rectifier fed from a supply having a frequency equal to the required control frequency. A metal-vapour rectifier G1 fed from an A.C. supply N has -control grids H1 which are connected to the cathode K1 through resistances R and a biasing battery B. Connected in parallel with the resistances R through spark-gaps F are the secondary windings Q3 of a transformer T3, the primary windings P3 of which are connected in the anode circuits of an auxiliary rectifier G. When current commences to flow in an anode circuit of the rectifier G a large voltage builds up in the associated secondary winding which causes breakdown of the spark gap and energization of the associated control grid. The transformer T2 feeding the rectifier G may be a phase-shifting transformer so that control of the ignition instant may be obtained. The Specification also describes an arrangement of inductances and resistance by means of which the polyphase current for feeding the rectifier G may be obtained from a single phase supply.

Class 12(1) A journal bearing which may have a steel backing, has grooves 2 machined in its bronze shell 1 which are filled by electro-deposition with soft antifriction metal 4, and is then machined so that the area ratio of the hard metal 3 to the soft metal 4 is in the order of 1:4, the shell and soft metal then being covered with a thin coating of electro-deposited soft antifriction metal. In a modification, the metal 4 is pressed or otherwise machined in the shaped shell or the flat strip which is formed into the shell. It is stated that in operation the initial uniform covering of soft metal wears first where it coats the ridges of hard metal, but the soft metal in the grooves spreads out as a film over the ridges and forms in time a series of narrow inclined planes favourable to the development of high load carrying oil films.
