Title: Improvements in the transference of and manufacture of liquid oxygen
IPC: F17C9/00
Filed: 1943-09-25
Abstract: 573,383. Making and pumping oxygen. AIR PRODUCTS, Inc. Sept. 25, 1943, No. 15747. Convention date, May 27. [Classes 8 (ii) and 102 (i)] In the manufacture of liquid oxygen by the fractionation of air, air under pressure enters a pipe 15 and passes through the tube bank 11 of a heat interchanger 10, the boiling coil 14 of a single fractionating column 13, and an expansion valve 18, the air, which is then in a largely liquid form, passing downwardly through the column. Pure liquid oxygen.from a pool 19 is cooled by passing through a heat interchanger 45 and then passes through the inlet valve 34 of a reciprocating pump 36. Gaseous nitrogen from the top of the column passes in the opposite direction through the interchanger 45 to cool the oxygen to a temperature about 6-8‹C. below its boiling point at column pressure, and then passes through a coil 49 around the pump cylinder. This coil removes heat at least equivalent to that produced in the liquid oxygen during action of the pump, to maintain its low temperature and avoid gas locking of the pump. The gaseous nitrogen and liquid oxygen then flow through pipes 21, 23 to the shell and tube bank 12, respectively, of the interchanger 10 in counter flow to the entering air, whereby they are brought substantially to atmospheric temperature and are discharged at any desired pressure through pipes 50, 47. Alternatively, liquid oxygen from the pipe 23 may be directed to a storage vessel in liquid form. Modifications include (i) a double fractionating column including an intermediate condenser; (ii) valved pipes which permit the nitrogen from the top of the column to flow direct to the interchanger 10; (iii) means for condensing gaseous oxygen before it enters the interchanger 45 so as to prevent any oil being carried with the oxygen into any part of the apparatus where detonative combustion might occur; (iv) an external refrigerating system supplying nitrogen, helium, or hydrogen to the interchanger 45 and pump coil 49.

Abstract: 1432972 Centrifugal separators; centrifugal filter ADVANCED PRODUCT ENG CORP 3 April 1973 [6 April 1972 7 April 1972 5 Jan 1973] 15901/73 Headings BIT and B2P In an apparatus for removing particulate matter from a fluid, e.g. gas, and of the type described in parent specification 1361712, an aerodynamic seal asserably 55, 56, Fig. 6, rotates with the shell 28 to prevent by-pass of the filter 24 by the fluid and the particulate matter. The seal assembly consists of vanes 56 mounted on a plate 55 supported by a flange 54 secured to the shell 28. Its function is to create a pressure rise from the inner to the outer diameter of the assembly so as to prevent any particle-laden fluid passing through the clearance 51 or leaking from the rotating shell 28 from passing radially inwards through the gap 52 and the discharge port 75. The apparatus may be used to separate liquid particles from air. In order to prevent any gas from escaping with the agglomerated liquid particles flowing down the inner wall of the shell 28 from escaping with the liquid, one or more liquid discharge tubes 41 provided in the shell open into one or more cups 42, or into an annular trough, having an upper opening 42a and containing, in operation, a quantity of the liquid being separated. Alternatively, the or each tube 41 may have a pigtail configuration, Fig. 5. When separating solid particles from air, liquid may be supplied through a spray nozzle 60 to agglomerate the particles and facilitate their separation by centrifugation. Further liquid may be supplied via tubes 64 through stationary nozzles 63 to backwash solid particles caught by the filter 24. The fluid after passing through the filter 24 flows successively through turbine vanes 25, a stationary radial diffuser 26 and a port 27. A fan or blower may be mounted upstream of the inlet to the apparatus to feed the polluted fluid under pressure. Alternatively, or in addition, a fan or blower may be connected to the outlet to suck cleaned fluid from the apparatus.

Patent GB-327897-A (GB)
Title: Improvements in tongs or wrenches for use in connection with oil or like drilling operations
IPC: E21B19/16
Filed: 1929-05-27
Abstract: 327,897. Shotter, G. F., and Elliott Bros. (London), Ltd. March 13, 1929. Transformers.-A current transformer for use with a measuring instrument has an adjustable gap in the iron circuit, so that different ranges of current may be measured, the iron core being in separable parts, for example hinged together, so that the core may be placed around a main conductor. The core is built up of laminae clamped in an aluminium or other non-magnetic casing of U- section and is in two parts 1, 2 hinged together by a pin 3 passing through parts 4, 5 of non-magnetic material extending from the casing, so that the pin is offset from the core. By this means a gap 7 in the magnetic circuit, in addition to the main gap 6, is formed when the parts 1, 2 are opened out. Opposed projections 14, 15 of magnetic material are arranged to move over one another as the parts 1, 2 are opened out, the projection 14 being bifurcated and the projection 15 moving into it. A magnetic shunt is thus formed which increases in value as the parts are opened. The projections 14, 15 may be parts of the laminations, or separate members. The secondary winding is in two parts 18, 19 mounted on the divided and hinged member 8. A spring 13 is provided for normally maintaining the parts 1, 2 closed, and handles 11, 12 permit them to be opened. The gap between the members 1, 2 in the closed position is measurably adjusted by means of a screw 27, on the part 2, abutting against a hard steel stop 26, Fig. 5, on the part 1. The screw 27 has a cylindrical part 29 in which are depressions 30 filled with materials of different colours. Each of these, when brought opposite a hole 31, indicates that the gap 6 is of the correct size to measure a particular range of current. Sheaths of insulating material 34 prevent contact between the main conductor and the core. In a modification, the magnetic shunt, the handles 11, 12, and the spring 13 are omitted and the hinge is not offset, the parts 1, 2 being held in the closed position by a hinged stirrup embracing both parts and having a U-shaped spring to press them together. A wound primary may be connected into the conductor carrying the current to be measured. A single highresistance instrument may be used for measuring current or voltage, switch-controlled resistances being inserted in the latter case. The transformer may be employed in connection with rectifiers to operate direct-current permanent magnet instruments. The measuring instrument may have a reference point for the indicator, instead of a graduated scale, in which case the gap in the transformer core is adjusted to cause the pointer to coincide with this mark, the current being indicated by the size of the gap. According to one of the Provisional Specifications, the core is held in the closed position by a thumb-screw on a pin swivelled on one part and passing through a gap in the other, also thescrew 27 has a pointer and scale to indicate the size of the gap.
