Abstract: A treatment apparatus of the present invention includes a hermetic door 115b and a retort 115c as an interface for taking out a gaseous emission containing vaporized substances from an object to be treated which is being heated in a reduced pressure state in a second hermetic chamber 103 while maintaining conditions in the second hermetic chamber. When the retort 115c is inserted into a first opening 103b of the second hermetic chamber, the hermetic door 115b in an open state is shielded from the second hermetic chamber 103, whereby condensation of the gaseous emission at the hermetic door is prevented. Accordingly, condensates can be taken out while conditions such as temperature and pressure in the hermetic chamber are maintained without the treatment apparatus being stopped. The productivity of treatment is greatly improved by continuous operation of such a treatment apparatus.

Abstract: Both ends of a bulb of a waste fluorescent lamp are cut off, a phosphor layer formed on an interior surface of the bulb is detached, so that mercury-containing phosphor powder can be obtained. The mercury-containing phosphor powder is subjected to a heating and reducing process with the dry-method, by mixing an organic reducing agent with the phosphor powder and heating the mixture, to vaporize and separate mercury from the phosphor powder. The vaporized mercury is then cooled and condensed, to collect mercury.

Abstract: An apparatus and system for its use for a continuous production on an alkali metal, preferably sodium metal, by a reduction of the metal hydroxide with methane or natural gas as a reductant.

Abstract: A reactor system that includes a reactor nozzle for use with a reactor vessel and process for its use for producing sodium metal, by a reaction of an alkali hydroxide, preferably sodium hydroxide, as a reactant, with methane gas as a reductant, at high heat.

Abstract: A retorting device for mercury containing material, with an oven, mercury trap and condensers capable of operation at pressures from atmospheric pressure down to 50 Torr with simultaneous temperatures up to 1500.degree. F. A dam within the mercury trap permits removal of liquid mercury separate from condensed solid amalgams, sludges and the like. The trap has provisions for removal of the sludges and amalgams from beneath the surface of water within the trap.

Abstract: Apparatus (1) for treating particulate material or powder (33) of a size capable of being fluidized in a retort (31) mounted for rotation on a pair of end axles (18, 41). Retort (31) is mounted on a tilt frame (5) for tilting movement in a vertical plane. Gas conduits (18A, 18B) are mounted within an axle (18) for the supply and exhaust of gas for retort (31). A conduit (55) mounted within the other axle (41) permits particulate material to be passed into or out of the retort (31) as shown in FIG. 1B. A removable injection assembly (90, FIG. 10) is utilized for the injection of additional particulate material. A removable sampling assembly (95, FIG. 11) is utilized for removing a sample of the particulate material from the retort (31).

Abstract: A self-contained air conditioner unit comprises an enclosure including a first and second intake apertures positioned to communicate with outside ambient air and first, second, and third outlet apertures positioned to communicate with a habitable space in which the air conditioner is placed. A water reservoir is disposed at the bottom of the enclosure. A two-section heat exchanger is disposed in the cabinet over the water reservoir, each section comprising a plurality of vertically disposed, alternating wet air channels and dry air channels defined by substantially parallel opposing heat-transfer partitions. The first-section dry-air channels communicate with a pre-mixing chamber at intake ends thereof and an air-distributing chamber at outlet ends thereof. Each first-section wet channel communicates with the distributing chamber at intake ends thereof and the second outlet aperture at outlet ends thereof.

Abstract: A sublimer assembly vaporizes zirconium tetrachloride in a Kroll reduction process. A retort for vaporizing the feed has a sidewall extending from a bottom wall with a peripheral heater adjacent to the sidewall and an internal heater extending through the retort. Substantial contact between the feed and the surfaces of the internal heater and retort sidewall is maintained so that the vaporization rate tends to cycle and the time required to vaporize the feed may be substantially reduced.
