A subaqueous well is completed by forcing a tube 44 encircling the well casing 16 into the ground below the water to extend above the surface of the water, cutting the casing adjacent the ground before or after forcing the tube, pumping water from the tube, installing a wellhead on the casing, and running flowlines 62 from the wellhead through the tube to above the surface of the water. Casing 24 is run into the casing 16 surrounded by conductor 14, the annular spaces between the casings and the casing 16 and conductor 14 are cemented, and the casing 24 is plugged. The space between the conductor and casing above ground is filled with sand and the casings and conductor are severed above the ground. A tube support structure 32 having an annular oil tank 38 is lowered over the stubs of the conductor and casings. The tube is lowered through the support and driven or jetted into the ground. The water is pumped from the tube, the casings are trimmed and wellhead equipment 46 is fitted after drilling out the plug. The flowline is connected to a lubricator 66 and a separator 68, the separator being connected by a line 40 to the tank.

Title: Improvements in or relating to the provision of heating apparatus on petrol-electric and like vehicles
IPC: B60H1/22
Filed: 1930-05-23
Abstract: 355,707. Heating liquids by electricity. ARMSTRONG, WHITWORTH, & CO. (ENGINEERS), Ltd., SIR W. G., 22, Gt. Smith Street, ORTON, A., 26, Linden Gardens, Nottinghill Gate, both in London, and BECKETT, C. M., 55, Wordsworth Drive, Cheam, Surrey. May 23, 1930, No. 15939. [Class 39 (iii).] Relates to petrol-electric and like vehicles in which a circulating heating liquid is heated by one or more electric heaters 1 supplied with current from a dvnamo-electric machine 2 and consists in controlling automatically the heater circuit by means of a pressure-actuated governor of known form which co-operates with electrical contacts 4 in the circuit of a solenoid 3 to open or close a contactor 6 in the circuit from the dynamo-electric machine to the heaters 1 according to whether the boiler pressure is above or below predetermined values. An electric signalling device, such as a lamp 5 situated in the driver's cabin, may be provided in circuit with the contacts 4 to indicate the state of the boiler pressure. The heaters 1 may be installed in a boiler heated also by the exhaust gases of the engine, or in a separate boiler connected to an exhaust-heat boiler, or a single electrically-heated boiler only may be provided on the vehicle. Contacts may be arranged on the driver's controller 9 in circuit with the control supply line 8 so that the supply of current to the heaters is interrupted when the whole of the power developed by the generator 2 is required for traction. The boiler is preferably fitted with a water-level safety device which by opening contacts 10 in the line 8 stops the supply of current to the heaters when the water falls below a certain level. The supply of water to the boiler may be effected by a pump driven by the engine cam shaft or by an electric motor, and the quantity of water is regulated by a byepass device which returns the feed water to the tank when the water in the boiler is at a certain level. In a modification, the energy of the vehicle is used to heat the boiler by means of the regenerative current derived from rheostatic braking of the traction motors, the change-over of current supply being effected either at the will of the driver or automatically ; such an arrangement is advantageous on mountain railways, in which long runs are made downhill with the Diesel engine stopped.

Abstract: 497,027. Win dscreencleaners; securing wiper arms on shafts. LUCAS Ltd., J., and SHAW, F. T. June 11, 1937 Nos. 16202 and 19869. [Class 138 (i)] [Also in Group XXIV] The wiper arm is secured on the actuating spindle by means of a sleeve on the arm and a split bush, rotation of a nut causing coacting inclined surfaces to tighten the bush on the spindle.

When a nut is screwed on to the reduced end of the bush, the latter is tightened on the spindle. A key h prevents relative rotation of the sleeve and bush. The bush may engage a circumferentially-grooved part or a collar on the spindle. In a modification, Fig. 5, the sleeve has a second inclined surface 'In cooperating with the inclined outer surface n of the nut to tighten the latter on the bush. One Provisional Specification describes a construction in which the nut is screwed on to the spindle and expands the bush so that the latter grips the sleeve, the bush having a positive connection with the spindle.

Title: Improvements in or relating to a manufacturing process of an electric metal resistance
IPC: H01L43/08
Filed: 1951-07-09
Abstract: 705,606. Making electric resistors by electrolysis; magnetic field-variable resistors. VOLTOHM PROCESSES, Ltd. July 9, 1951 [July 13, 1950], No. 16209/51. Classes 37 and 41 A process of producing magnetic fieldvariable metal resistance elements in any desired pattern by electrolytically depositing the metal of the resistance element on a conductor support which is subsequently partly or wholly dissolved away chemically is characterized in that before dissolving away any of the conductor support an insulating base for the resistance element is applied. The invention is particularly concerned with the production by this process of bismuth, antimony and tellurium magnetic field-variable resistors. In Fig. 6 a completed resistor is shown comprising a bismuth ribbon 3 of sinuous pattern, Fig. 1, embedded in hardened varnish 4, 5 and connected to copper terminal strips 6. The steps leading to this product are outlined in Fig. 1 to 3 and Fig. 5. A copper plate 1 Fig. 1 and 2 is masked with varnish 2 and the bismuth ribbon 3, Fig. 3, is electrolytically deposited in the unmasked area. The varnish resist 2 is then removed and the bismuth coated side of the copper plate 1 covered with a hardened or polymerized "Araldite" (Registered Trade Mark) or silicone varnish or other plastics varnish constituting a thin insulating support 4 Fig. 5. The terminal areas of the copper plate 1 are varnish protected and the whole plate 1 is then dipped in a selected chemical solution which dissolves away the unwanted copper and is non-corrosive with respect to the bismuth and varnish. Finally top layers 5 of insulating varnish are applied and the Fig. 6 product is realized. The electrolytic bath may have the following composition : Carbonate of bismuth 40 grams per litre-Perchloric acid at 60 per cent. 100 grams per litre-Glue 0.1 grams per litre ; also the copper dissolving solution utilized may consist of a 10 per cent. solution of trichloreacetate of ammonium. In a modification Fig. 4 the bismuth deposit is applied to the whole of one side of the copper plate 1 and the unwanted bismuth removed by acid treatment or mechanically using, e.g. a tracing machine. A metallized insulating support may be employed instead of the copper plate 1 and may consist of celluloid, cellulose acetate or polystyrene coated with silver or copper so that a varnish resist is not necessary as exemplified Fig. 8 wherein 8 is a metal layer on a non-conducting support 7. If a conducting support plate is used having a dissolution potential higher than that of the electrolytic coating the plate should be coated with a metal having a lower dissolution potential, e.g. in the case of bismuth electrolysis a copper or silver coating may be used. Figs. 9 and 11 are examples of wound ribbon resistors produced by the process with the ribbon 3 in Fig. 11 effectively a bifilar winding so that the resistor is non-inductive.

Abstract: 358,038. Polishing lacquered surfaces. STRATFORD, H. R., Euclid Avenue, Cleveland, Ohio. U.S.A. May 27, 1930, No. 16345. [Class 60.] Disc apparatus ; wheels.-A lacquered surface is smoothed and polished by a rapidly rotating felt or like disc 10 which may be carried by a flexible metal disc 12. Abrasive is applied to the disc or to the work and a liquid is supplied to the centre of the disc. Centrifugal action causes the abrasive to be thrown from the edge of the disc. On continued rotation with the supply of liquid cut off, the disc becomes dry and the heat generated causes the lacquer to soften and flow to form a polished surface. The disc is rotated by a flexible shaft through gearing 6, 7 contained in a casing 2 fitted with handles by which the disc is held against the work. Liquid is supplied through a pipe 13 and ports 14, 15.
