Title: Improvements in or relating to pumps and pump systems and evaporator systems
IPC: F04C7/00
Filed: 1961-03-14
Abstract: 975,522. Centrifugal and liquid-ring pumps. NASH ENGINEERING CO. March 14, 1961 [April 20, 1960], No. 9301/61. Heading F1C. [Also in Division B1] A pump for handling gases and vapours, or liquids, or mixtures thereof, comprises a compressor portion having at least one lobe, a compressor rotor having radially extending blades and a pair of annular end shrouds, a liquid pumping portion comprising a volute means and an impeller having impeller blades integral with one of the compressor rotor end shrouds and shaped to provide a central inlet, whereby fluid is taken in centrally from the discharge of the compressor portion and directed towards the volute means, and shaft means connected to the impeller for imparting rotation to the rotor via rotation of the impeller. A plant for distilling brine comprises an evaporator 10, Fig. 1, and a condenser 12. The evaporator may be operated by the waste heat in the cooling water of an I.C. engine. To keep the salinity within the evaporator reasonably constant, more brine is supplied to it than is needed for evaporation, the excess being withdrawn through a line 32 by a pump 30. A further pump 14, driven by the same motor 34 as the pump 30, withdraws the distillate from the bottom of the condenser 12 through a line 18 and removes any air accumulating in the condenser through a line 16. The distillate and air are both accompanied by uncondensed vapour, which condenses within the pump 14. The pump 14 discharges a mixture of distilled water and air through line 20 to a separator tank 22, where excess air is separated and vented at 24 to atmosphere. Distilled water containing a normal amount of absorbed air is delivered through a line 26. As shown in Fig. 2, the pumps 14 and 30 each comprise a liquid-ring first stage feeding a centrifugal second stage, the respective impeller blading 66 and 64 being carried by a common impeller 58. The liquid-ring stage may comprise one or several lobes, two lobes 56 being provided in the embodiment shown. Pump 30 has a single inlet but pump 14 may instead have two separate inlets 48 and 50 connected respectively to the lines 16 and 18. Some of the water is returned from tank 22 to the pump 14 through a line 28 for sealing purposes and to assist in condensing the vapour entering the pump. This pump construction is also suitable for returning hot condensate to a boiler in a process system where the pump has to handle condensate containing gas and air, the gas and air being removed from the circuit in a separation chamber.

Abstract: 798,834. Weighing apparatus. RANSOMES & RAPIER, Ltd. March 28, 1956 [March 30, 1955], No. 9322/55. Class 143. In a concrete mixer a loading skip 1 of the kind which is moved about a separable bearing 4, 6 by a cable 3, the bearing shaft 4 is removed from the brackets 6 and the weight of the skip is transferred to a weighing mechanism automatically when the skip is fully lowered and rope 3 is slack. This is effected by chains 12 which are suspended from the weighing mechanism W and are connected to cams, eccentric rollers or sprockets 11 rotatable with shaft 4 in such a manner that lowering of the skip raises the shaft. Horizontal reaction of the lowered skip is taken by bars 15 which are engaged by shaft 4 and shock absorbers 10, and which are guided for substantially vertical movement by knife edge seated links 16, 17. The chains 12 are connected to a hydraulic capsule and gauge units by levers 23, Fig. 1 (not shown), which compensate for asymmetrical loading of the skip and for use of the apparatus in out of level conditions. In a modification (not shown), the weighing mechanism comprises either a steelyard or a pendulum or spring counterbalanced scale.

Title: Improvements in or relating to a valve construction
IPC: F16K3/10
Filed: 1952-04-15
Abstract: 719,249. Valves. VULCAN RESEARCH CORPORATION. April 15, 1952 [June 7, 1951], No. 9386/52. Class .135 A valve comprises a ring seat member connected co-axially in a conduit and movable longitudinally thereof to co-operate with a valve closure member, the seat being moved by an impeller which is separate from, but engages, the seat member so that deflections of the impeller will not be transmitted to the seat, and means is provided for engaging the impeller and moving it longitudinally with respect to the conduit. In an embodiment, two flanged ring seat members 5, 6 are bolted in a conduit and a goggle valve plate 2 can s'ide in between them. The seats carry tongues 14 which engage in slots at the mid-points of the sides of two frame members 10 in the shape of equilateral triangles so that movement of the frames towards and away from each other will cause the seats to press against the valve plate or to release it to allow it to be moved. The frames are connected together at their apices by shafts 22 which screw into fixed nuts 23 carried by the frames, and as the threads at the ends of each shaft are of the same hand but of different lead, rotation of the shafts will move the frames relatively to each other. The shafts are rotated synchronously by means of a chain 26 which passes over chain wheels 25 carried by the shafts, and movement of chain 26 is effected by a further chain 38 through reduction gearing. The frames are guided in their movements by means of pins 18, 19 which engage in members 16, 17, respectively, depending from the frames, and pin 19 constitutes the pivot pin for the goggle plate 2. The latter is formed with rack teeth 34 engaging a pinion on a shaft 28 carrying a chain wheel and chain 30, the latter constituting the operating member for the valve plate. Specification 719,251, [Group XXIV], is referred to.

Title: Gas blast circuit-breaker
IPC: H01H33/56
Filed: 1965-03-08
Abstract: 1,079,820. Gas-blast circuit-breakers. ETABLISSEMENTS MERLIN & GERIN S.A. March 8, 1965 [March 20, 1964], No. 9799/65. Heading H2B. A gas-blast circuit-breaker has a compressed gas reservoir 11 forming, or directly connected to, an arc extinguishing chamber or chambers and supplied from a source of compressed gas through a supply conduit 12, a check valve 14 being provided in the conduit 12. The contacts are opened by supplying compressed gas to a control conduit 20, 19 so as to operate a valve 27, 29. When this valve operates, a control pipe 26 to the contact operating mechanism ceases to be vented at 31 and is connected through a pipe 21 to the reservoir 11. Should the pressure in the conduit 12 fail, the valve 14 closes to prevent loss of pressure from the reservoir 11 and pressure is no longer applied to a piston 16 through a pipe 17. The valve element 18 connected to the piston 16 changes over so as to shut off the control conduit 20 and to connect the conduit 19 to the reservoir 11 through the pipe 21. This opens the circuitbreaker contacts if they were closed at the time the supply pressure failed or prevents the closing of the contacts if they were open at that time.

Title: Improvements in and relating to lathes for cutting or forming screw threads
IPC: B23G1/32
Filed: 1956-03-29
Abstract: 804,387. Screw-cutting-lathes. HARRISON & SONS, Ltd., T. S., and TURNBULL, D. H. March 6, 1957 [March 29, 1956], No. 9848/56. Class 83 (3). A lathe in which a leadscrew controls the travel of the thread-cutting or forming-means, has an additional lead-screw or masterscrew which controls a power or servo-device for adjusting the thread-cutting or forming-means relatively to the lathe-saddle in the direction of travel thereof, so that the accuracy of the thread formed is determined by the master-screw. The work 7 is driven from a conventional headstock 20 driven from an electric motor 18 and belts 19. Pick-off gears 23 drive a feed-box 22, and a conventional lead-screw 13 moves the saddle 1 through a half-nut 17 for screw-cutting. The tool-rest 2 may carry a single-point-tool, a milling-head, or a rotatable cutting-head 4 embracing the work. The latter cutting-means is driven by a separate electric motor 5. The tool-rest is slidably mounted on the saddle on guides 8 in the direction of movement of the saddle, and is moved by a hydraulic piston 9 anchored to the saddle and supplied with pressure-fluid from a pump 11 controlled by a spring-pressed pistonvalve 19. The latter is moved by a lever 24, one end of which bears against a second half-nut 15 engaging a second lead or master-screw 14, driven at the same speed as the screw 13. Any changes in the relative positions of the nut 15 and saddle 1 due to inaccuracies in the leadscrew 13 are thus communicated, through the lever 24, to the valve 12, and the piston 9 and cylinder are then supplied with pressure-fluid to correct the inaccuracy.

Title: Improvements in or relating to stabilized heating oil
IPC: C10L1/24
Filed: 1952-04-21
Abstract: A petroleum hydrocarbon fuel oil containing at least 10 per cent. by volume of stocks derived from thermal or catalytic cracking operations is stabilized by intimately contacting it with an alkali, alkaline earth or ammonium salt of an acid derived from phosphorus, antimony, arsenic or bismuth, together with a detergent consisting of an oil soluble alkali or alkaline earth sulphonate or a metal soap of a C16-C24 fatty acid or a naphthenic acid.  The preferred detergents are the petroleum sulphonates of Na, Ca, Ba, Sr and Mg.  The preferred salts are sodium salts of phosphorus acids, especially Na3PO4. Other salts used include Na2HPO4, NaH2PO4, Na4P2O7, Na3PO3, (NH4)2HPO4, and sodium arsenite, arsenate, and bismuthate.  They may be anhydrous or hydrated.  The amount added is about .0001-.1 weight per cent. of anhydrous salt.  The salt may be added as a mixture with the petroleum sulphonate containing about 2-20 per cent. of the salt. About .0005-5 weight per cent. of the mixture is used.  A complex may be formed by adding an aqueous solution of the salt, e.g. Na3PO4, to an oil concentrate of the petroleum sulphonate, and heating to 300 DEG  F. to dehydrate.  The concentrate of the complex may then be used to stabilize fuel oils.  Stability tests on a commercial fuel oil consisting of a blend of catalytically cracked, thermally cracked and virgin stock are given, various phosphates in concentrates of a sodium petroleum sulphonate in naphthenic lubricating oil being added.  Tests on other salts added as concentrates in lubricating oil containing sodium petroleum sulphonate are also given.  Stability may be further increased by adding the complex together with an alkaline earth metal alkyl phenol sulphide, e.g. barium isooctyl phenol sulphide.  Examples wherein an addition of the latter equal to .002 and .004 weight per cent. are given.  Other additives may be incorporated. Specification 727,153 is referred to.
