摘要： A life support system for an undersea habitat which derives oxygen and potable water directly from the sea, without connection to shore or supply ships. Dissolved gases including oxygen and nitrogen, are stripped from sea water by passing a stream thereof in counter-current with rising steam derived from sea water heated in the boiler of a rectification tower. Oxygen is then separated from the other desorbed gases and conveyed to the habitat. The exhaust gas from the habitat is passed through a carbon dioxide absorber before being recirculated in the habitat. The carbon dioxide from the absorber and the residue of desorbed gases from the stripper, including nitrogen, are reabsorbed in the sea water, which is ultimately cooled and returned to the ocean.

摘要： An improved system for manufacturing carbon black in which a central nozzle, which emits a hydrocarbon spray, is surrounded by a plurality of auxiliary nozzles from which high velocity oxyfuel flames are emitted. The auxiliary nozzles are surrounded by pilot nozzles and pressure and flow regulating means are provided in the feed conduits to both the auxiliary nozzles and pilot nozzles surrounding same so as to enable independent control of the flow rate of the oxy-fuel mixture to said auxiliary and pilot nozzles.

摘要： A power supply is described for use with an electron gun employed in an electron beam furnace system. The power supply includes a transformer and a rectifier connecting the secondary of the transformer to the electron beam gun for supplying current thereto. The power supply also includes a semiconductor-switching circuit connected to the primary of the transformer for supplying current to the primary. The switching circuit is controlled by a pulsing circuit, and a trigger circuit is controlled by a pulsing circuit, and a trigger circuit is connected to the pulsing circuit and to means for sensing a rise in current to the electron gun in the presence of an arc. Upon the sensing of such rise in current, the trigger circuit disables the pulsing circuit to thereby render the switching circuit inoperative and cut off current to the electron beam gun.

摘要： The present invention relates to the novel compounds 1,1,2,2tetrafluoroethyl trichloromethyl ether (CHF2CF2OCCI3); 1,1,2,2tetrafluoroethyl dichloromethyl ether (CHF2CF2OCHC12); and 1,1,2,2-tetrafluoroethyl fluorochloromethyl ether (CHF2CF2OCHFCI). The compounds are prepared through selective stepwise chlorination and fluorination of 1,1,2,2tetrafluoroethyl methyl ether. The compounds are useful as anesthetics and as solvents and dispersants of fluorinated materials.

摘要： Sewage effluent from a primary treatment plant is initially pumped to a vacuum deaerator for removal of dissolved air and hence nitrogen, from the effluent stream. This stream, deaerated as required, is joined with a stream of recycled activated sludge and a stream of pure oxygen in quantity sufficient to meet the ''''biological oxygen demand'''' (BOD) of the combined effluent and recycled activated sludge. The confluence is pumped through an underground pipeline reactor having a static mixer for enhancing contact between the oxygen, aerobic bacteria and organic pollutants. The reactor stream BOD is progressively reduced to the required level at the reactor outlet. A downstream clarifier separates the reactor activated sludge from treated waste water and separated sludge in part is returned for recycling to the inlet of the reactor. The clear waste effluent from the clarifier is sent to tertiary treatment units or to receiving waters.

摘要： A method is described for evaporating an alloy from a single crucible in a vacuum enclosure. A solid bar of alloy is fed upwardly into the crucible from the bottom thereof. The alloy is heated to form a covering pool and to produce evaporation. The feed rate of the solid bar is regulated to maintain a substantially constant level of molten alloy relative to the crucible.

摘要： An inductive reactor is described comprising an outer core body having a plurality of planar laminations of low magnetic reluctance material and a center leg spanning the hollow interior of the core body. A winding surrounds the center leg. The center leg is comprised of a plurality of parallel elongated sections extending along the length of the outer body and spaced from each other to form parallel nonmagnetic planar gaps. Each section is comprised of a plurality of elongated parallel planar strips of low magnetic reluctance material perpendicular to the planes of the laminations and the planes of the gaps.
