Title: Electrodeposition of Aluminium Using Molten Electrolyte
IPC: C25C3/12
Filed: 1980-03-21
Abstract: An anode composition is used as the sole source of aluminum and comprises an aluminous material such as aluminum oxide and a reducing agent such as carbon. Electrodeposition is achieved at low temperatures and low electrical potential by the electrolysis in a fused salt containing the composite anode. The anode reacts to produce aluminum ions during the electrolysis, aluminum compound ionized at the anode is electrolytically reduced to molten aluminum at the cathode and an anion formed at the anode reacts to produce CO2 gas at the anode. In one operational mode a porous membrane passes electrolyte or other dissolved material while withholding undissolved impurities. Aluminum may be electrodeposited, at a temperature as low as the melting point of the metal and with the use of an all fluoride containing bath and the composite anode. Dimensionally stable cells for the electrodeposition have sloped walls forming electrodes that permit the maintenance of a reduced anode current density as well as anode- cathode spacing when using the low temperature non-aggressive baths permissible with the particular composite anode composition.

Title: Improved drain digging machine
IPC: E02F5/10
Filed: 1980-05-12
Abstract: A mole drainer comprises a main elongate beam (10) which extends from front to back and is adapted to be attached at its front end to a towing vehicle. A mole (24) is carried at the lower end of an adjustable arm (22) at the rear end of the beam (10) and is adjustable relative to the beam on elevated mounting (74) such that a free space is provided between the rear of the main beam (10) and the leading edge of the arm (22) and on either side of and to the rear of the arm. The space allows trash which otherwise would build up on the underside of the beam (10) to be freed just before impact by the leading edge of the arm (22) so enabling the latter to deflect the trash more efficiently to one side or the other. The leading edge (98) of the arm (22) can be feathered to produce a sharp cutting edge so as to cut and breakup the trash impaled thereon. The elevated mounting may be a subsidiary beam (74) or the main beam may simply be bent to form a Z-bend at the rear end. <IMAGE>

Patent GB-2096416-A (GB)
Title: An emergency electricity power supply for a fluorescent lamp
IPC: H05B41/285
Filed: 1982-01-27
Abstract: The emergency electricity power supply includes a battery B which feeds a DC-DC converter delivering an output current which varies as an inverse function of the output voltage. Thus it can supply both high current at low voltage for heating the filaments and low current at high voltage for running the lamp once triggered. The DC-DC converter comprises a control unit (2), eg an IC of the 555 type, which delivers signals of predetermined duration to a transistor (T3) in series with the primary (E1) of a transformer whose secondary winding powers the lamp via a diode (13). An inhibitor unit (15) is controlled by the voltage at the transistor collector and delivers an inhibiting signal to the control unit during a period required for recovering in the secondary winding the energy stored in the primary winding, this period being inversely proportional to the voltage at which the energy is recovered. A circuit (20) is triggered by an overvoltage at the transistor collector to inhibit the central unit. <IMAGE>

Title: Fluid pressure relief system actuator
IPC: F16K17/10
Filed: 1981-06-11
Abstract: Actuator head for a pressure relief valve (1) having a valve element (11) spring biased to a closed position and arranged to be movable under the action of a fluid pressure medium in order to allow the escape of the fluid pressure medium through the valve for pressure relief purposes. The actuator head comprises an actuator (3) which is coupled with the valve element (11) and has a member (21) displaceable in response to fluid pressure applied thereto. A linkage (22, 19, 12) couples together the valve element (11) and the actuator (3) and has a lost-motion connection (72) which allows the valve element (11) to move against its spring biasing (13) for pressure relief purposes without imparting movement to the displaceable member (21) of the actuator (3). Biasing means (27) is arranged to oppose displacement of the displaceable member (21) of the actuator (3), and control means (4, 5) is provided to control the supply of fluid pressure to said displaceable member (21). The displaceable member (21) is arranged to be displaceable upon the application of fluid pressure to the member by said control means, so as to apply a supplementary valve-closing load to the valve element (11) via the linkage (22, 19, 12). In addition, a failsafe mechanism is coupled with the linkage in such a way that the mechanism is movable with and forms part of the linkage during normal application of a supplementary loading by the actuator (3), but the mechanism is convertible, when the displaceable member (21) remains unintentionally in a displaced position under the action of fluid pressure and when the valve element (11) of the relief valve (1) carries out relief pressure movement, to a fail-safe mode in which the mechanism no longer forms part of the linkage (22, 19, 12) whereby no action is exerted between the actuator (3) and the valve element (11) via the linkage during the relief pressure movement of the valve element (11). <IMAGE>

The termination manufacturing procedure may alternatively be employed in connection with other electrical components.

Title: Well flow control apparatus
IPC: E21B23/06
Filed: 1982-02-16
Abstract: This application discloses apparatus in which a body means 12 having a bore 12A therethrough connected as part of a tubing string is packed off within a well bore, and means including a passageway 15, 16 in the body means bypasses the packer P to connect the annulus about the tubing string above and below the packer. The packer P is expanded into engagement with the well bore upon release of a means 24 for locking it in an inoperative position, and a means for so releasing the locking means includes a piston 25 in the passageway which in responsive to control fluid supplied through a control line 20 in the annulus which connects with the passageway. Upon release and setting of the packer, the piston 25 is removed from the passageway and circulation of well fluid through the connecting means between the annulus above and below the packer is controlled by a safety valve which normally closes the passageway, but which is responsive to control fluid supplied thereto through the same control line. Each of the means for connecting the control line with the passageway in order to release the packer, and alternatively establishing safety valve controlled circulation of well fluid through the connecting means comprise tools which are alternately landed within and retrieved from a pocket 13 formed in the body means to one side of its bore. <IMAGE>
