Abstract: 1431275 Manufacturing electric incandescent and discharge lamps THORN ELECTRICAL INDUSTRIES Ltd 5 June 1973 [6 June 1972] 26398/72 Headings H1F and H1D [Also in Division C7] In a method of making an electric lamp in which a lead-in conductor is sealed through the lamp envelope and terminates outside it, an electrical terminal is provided by disposing the outer end of the conductor in a well having a wall which surrounds the conductor and filling the well with an alloy exhibiting superplasticity; the alloy is then heated to the temperature below its melting temperature at which it behaves superplastically to cause it to flow into a compact mass in intimate contact with the conductor to form at least part of the terminal. As shown in the incandescent filament lamp in Fig. 1 the terminals may be of the Edison screw type with the conductor 13 embedded in a mass of superplastic alloy 19 filling a brass or aluminium ferrule 18 centred in the heat resistant insulating material 20 filling the brass or aluminium cap shell 16. The other lead-in conductor 13a may similarly be affixed to the shell 16 using a mass of superplastic alloy, alternatively it may simply be trapped between the shell 16 and the cement 17 bending the envelope 12 and shell 16. Alternatively the terminals may be of the bayonet type with both terminals formed as for conductor 13 in Fig. 1. In these embodiments the metal ferrule 18 may be dispensed with and the alloy mass 19 formed directly in a hollow well in the insulating material 20. The ferrule 18 of the well in the insulator 20 preferably have re-entrant portions to key the alloy mass firmly in place. Alternatively, Fig. 4, the terminal may be in the form of a pin or post in the form of a metal sleeve 45 filled with superplastic alloy 46 and the embedded conductor 44 has an irregularity 49 at the end thereof to strengthen the joint. The lamp can also be a metal vapour arc discharge lamp, a fluorescent lamp, automobile or projector lamp for example. Preferably the superplastic alloy has the composition 22% by weight aluminium and 78 % by weight zinc and is heated within the range 250-300C. to render it superplastic. Other suitable alloys are also listed. The alloy may be heated by focused infra-red radiation and some alloys may require a subsequent heat treatment to prevent its superplastic properties reappearing on heating during service.

Filed: 1976-06-28
Abstract: 1492345 Raising liquids OTIS ENG CORP 28 June 1976 [14 July 1975] 26760/76 Heading F1R [Also in Division E1] A side pocket mandrel 10 for use in a well tubing string includes a side pocket landing nipple 24 for supporting a gas lift valve 25, the mandrel having ports 54 in its side wall opening into the side pocket landing nipple 24, and a sliding sleeve valve 26 in the landing nipple 24 for opening and closing the ports 54 in response to insertion and removal of the well tool in the nipple 24. As described the sleeve valve 26 includes ports 74 and seals 80, 81, 83, 84 and is provided with upwardly extending collet fingers 70 having heads 72. When no gas lift valve 25 is present the valve 26 occupies an upper position (not shown) in which the ports 54 are bridged by the seals 83, 84 to close the ports 54 and in which the collet heads 72 engage an annular recess 45 in the landing nipple 24 to lock the valve 26 in its closed condition. When a gas lift valve 25 is inserted into the landing nipple 24 using a kick over tool (not shown) a shoulder 134a on the gas lift valve 25 engages the sleeve valve 26. Further downward movement of the gas lift sleeve valve 25 causes the collet heads to cam inwardly into a recess 96 on the gas lift valve 25 (thus latching the valve 26 to the valve 25) and moves the valve 26 downwardly until the bottom of the valve 26 engages a stop ring 61 as shown in Fig. 1B, the gas lift valve 25 then being locked in position by locking dogs 155. The valve 26 is then open and gas can pass from the well annulus through ports 54, 74, through an entry port 103 in valve 25, the body of valve 25 and exit 120 and through ports 50, 51 into the main bore 22 of the mandrel 10. The gas lift valve 25 can be removed by a retrieval tool (not shown) which engages fishing head 151 on the valve 25, retracts the locking dogs 155 and lifts the valve 25 upwardly from the landing nipple 24. During this upward movement the valve 26 is also raised to its closed position when the collet heads 72 expand outwardly into the recess 45, thus releasing the valve 25 from the valve 26.

IPC: C01D1/02
Filed: 1962-07-13
Abstract: <PICT:1009113/C6-C7/1> A fused alkali metal halide is electrolysed using a molten lead cathode to yield an alkali metal/lead alloy. Molten lead flows at 15 along the base of cell 10 having metal body 12 and insulating refractory brick support 14. The lead enters at 80 and the resulting alloy is withdrawn through perforated sleeve 94 from end compartment 89 defined by transverse wall 88.  Anodes 50 are mounted in the graphite lid 30, which is sealed by the depending flange 42 in the fluid filled channel 34.  Molten sodium or potassium chloride is fed into the cell at 82 and chlorine is withdrawn through channels in the anodes.  The alloy withdrawn contains 10-50% of Na and passes to vaporizer 120 for removal of 25-50% of the Na as vapour, by heat, and/or evacuation.  The Na vapour is subsequently oxidized in 125 (see Division C1) while the alloy is returned through salt fuser 130 to the cell.  The cell is heated by molten lead flowing in pipe 120.  An auxiliary outlet 70 is provided for venting the cell, and the power is conducted through the cell body and lid. The current may be varied to vary the lead alloy composition.  In electrolysis of sodium chloride it is 150,000 amps., 4.5 volts at 850 DEG C.  With potassium chloride the cell operates 720  DEG C. and another salt, e.g. calcium chloride, is added to depress the melting point. Specifications 986,223 and 1,007,778 are referred to.ALSO:<PICT:1009113/C1/1> An alkali metal oxide is produced by electrolysing a fused alkali metal halide with a molten lead cathode, to form an alkali metal/lead alloy from which the alkali metal is evaporated and oxidized.  The molten lead flows through a suitable electrolysis vessel containing fused NaCl or KCl (Fig. 1, not shown). The alloy withdrawn contains 10-50% of alkali metal, and passes to a vaporizer where 25-50% of the alkali metal is vaporized by heat and/or evacuation. The remaining alloy is returned to the cell. The sodium vapour passes through a baffled chamber or cyclone separator to remove entrained lead and enters the oxidizer chamber 135 at 122. The oxidizer may be provided with a water cooling jacket 138.  Dry oxygen containing gas, e.g. air, also passes into 135 through the jet injector 156 under 2 lb. pressure. Stoichiometric amounts of O2 may be controlled by reducer valve 180 to form monoxides, dioxides and peroxides of sodium and potassium. The oxide separates on baffles 142, which may be cooled by liquid sodium, and is withdrawn at 145. Effluent gases from 136 pass through a cyclone separator and into water. The injector may be provided with 2 concentric sleeves (Fig. 3, not shown) one stationary, the other rotatable, so that registration of apertures in the two sleeves controls the passage of alkali metal vapour into admixture with the air. The air may be precooled to 0 DEG  C.  Specifications 986,223 and 1,007,778 are referred to.
