Filed: 1937-10-26
Abstract: 486,725. Underfeed stokers. DAY, C. (Steel Products Engineering Co.) Oct. 26, 1937, No. 29160. [Class 51 (i)] In an underfeed stoker comprising a firepot 11, Fig. 3, fed with fuel from a hopper by a conveyer which feeds the fuel through a duct 12 into a retort 18 forming the lower portion of the firepot, air being supplied to the firepot through tuyeres 3 from a plenum chamber 27 surrounding the retort and supplied with air by a fan, air and gases within the retort chamber are prevented from flowing back through the fuel conduit 12 by causing them to pass through a passage leading from the retort to the tuyere discharge openings or elsewhere. Air from the plenum chamber 27 is led through a T-shape passage 36 to the fuel conduit 12 through an opening 39 or into the retort through a passage 60. Such air upon entering the retort passes with combustion products into a chamber 47 and thence to a passage 40 formed between two tuyere blocks 30 to tuyere openings 41. In the modification shown in Fig. 7, a chamber 53 leads air from the plenum chamber to the fuel conduit and retort and such air with combustion products may pass through a pipe 57 to the tuyere nozzle 34.

Abstract: 986,234. Two-part couplings. SOURIAU & CIE. July 31, 1962 [Sept. 8, 1961], No. 29318/62. Heading H2E. The contacts of a plug-and-socket connector are mounted in a mass of elastomer insulation by means of hard springy sleeves adhesively joined to the insulation and having opposed shoulders which abut against complementary shoulders on the contacts to prevent longitudinal movement of the latter. The sleeve 15, surrounding a complementarily-shaped rod portion on socket contact 5, has a longitudinal slit extending from its forward end past socket shoulder 13 to allow the socket 5 to pass through its reduced diameter bore portion. When socket 5 is pushed through from the rear of body 1, its front part causes the slit sleeve to expand until shoulder 13 passes the corresponding sleeve shoulder, when the latter snaps back. A second shoulder 16 on rod 7 prevents any motion in the opposite direction, and to withdraw the socket a tool must be inserted through the front body opening and around socket 5 to open the slit portion of sleeve 15. The plug contacts 9 with rods 11 are similarly mounted in body 2. Sleeves 15, which are preferably of springy metal such as phosphor bronze, spring steel, may be joined to their respective bodies during moulding, or inserted into shaped bores and then joined by a heating process.

Title: Improvements in or relating to production of uranium and its compounds
Inventor: MANN JOHN ERSKINE
IPC: C01G43/06
Filed: 1954-10-21
Abstract: Uranium pentafluoride enriched in the isotope U235 is produced by reacting enriched uranium hexafluoride with uranium tetrafluoride in substantially equimolecular amounts, the uranium tetrafluoride being in the form of a fluidized bed.  Reaction may take place at 200 DEG C., the bed of uranium tetrafluoride being fluidized by the vapour of enriched uranium hexafluoride.  The enriched uranium pentafluoride may be disproportionated by heating to 400 DEG C. in vacuo or an inert gas stream to liberate uranium hexafluoride and leave enriched uranium tetrafluoride; in this process also the uranium pentafluoride may be in the form of a fluidized bed.  The uranium hexafluoride liberated may pass to a diffusion plant for enrichment and use in treating further uranium tetrafluoride; the enriched uranium tetrafluoride may be reduced to uranium metal.  An isotope exchange unit is described comprising a series of linked reaction sections and disproportionation sections, uranium hexafluoride and uranium tetrafluoride flowing countercurrently through the series.

Title: Electric relays or switches with time lag devices
IPC: H01H29/28
Filed: 1938-10-14
Abstract: 519,150. Mercury switches. MESTITZ, E. (Drahonovsky, P.). Oct. 14, 1938, No. 29865. [Class 38 (v)] In a short-time switching arrangement suitable for staircase lighting &c. depression of a push button 23 completes the circuit to a heating coil 9 in a gas-chamber 1, the consequent expansion of gas causing the movement of mercury in an M-shaped tube connecting the chamber 1 to a chamber 2 so that contacts 12, 13 in the load circuit are bridged at 5. In the form shown in Fig. 1 the heating circuit includes the coil 20 of an electromagnetic relay which by attracting a core 18 short-circuits the push button 23 and maintains the heating circuit closed after the push button is released. After a certain time the mercury descends so as to break at 4 the circuit to the heater 9 and coil 20. The gas in 1 now cools, the mercury moves back but the heating circuit is not again completed since the maintaining circuit is now broken. Eventually the mercury reaches its original level and the circuit to the load 22 is broken at 5. In a modification, Fig. 2, the electromagnetic relay 20 is replaced by a thermal relav mounted in the vessel 2. Depression of a button 23 completes the circuit to the heater 9. The consequent movement of mercury forces the gas in the vessel 2 through a hole 29 and forces mercury in a vessel 28 to move up a narrow funnel 25 to bridge contacts 26, 27 in a maintaining circuit, Further pressure causes bubbles of gas to pass by the bubble of mercury held in the funnel 25. When mercury in the bulb 1 has sunk so as to break the heater circuit at 4 the gas in 1 contracts, and the mercury at 25 falls so as to break the maintaining circuit. Subsequent reunion of the mercury at 4 cannot now remake the heater circuit, so that cooling continues till the load circuit is broken at 5. The amount of mercury in the vessels 1 and 2 may be adjusted by pouring some of it into a side tube 11.
