The blood filter employs a bed of fibers between about 1 and 100 microns in diameter, the outer surface of which is formed of impermeable carbon. Suitable fibrous substrates may be coated with vapor-deposited pyrolytic carbon, and the fibers may be supported between upper and lower screens which are likewise coated.

Abstract: Dissolved organic compounds in waste water resulting from coal degassing or gasification processes are removed by extraction with a solvent which is substantially water-immiscible, the solvent residues in the waste water are removed by inert gas scrubbing, and CO.sub.2, H.sub.2 S and NH.sub.3 in the waste water are removed by heating and steam contacting. NH.sub.3 is effectively removed in a steam gas/liquid contacting column by feeding the condensed head product of the column back to the top portion thereof, withdrawing a portion of the condensate from the column at a level intermediate the top and bottom portions of the column, treating the condensate in admixture with waste water containing CO.sub.2, H.sub.2 S and NH.sub.3 in a deacidification gas/liquid contacting column, and feeding the sump product of the deacidification column to the first column at a region below the region at which the condensate is withdrawn but intermediate the top and bottom portions of the NH.sub.3 -removal column.

Abstract: A device for separating dissolved or entrained gas from a liquid and particularly for separating dissolved or entrained air from oil used in hydraulic systems or as electrical insulation. Contaminated oil, containing dissolved or entrained gas, is introduced into a degassing chamber where the gas is removed in a relatively low pressure atmosphere. The oil, with at least part of the gas removed is withdrawn from the chamber through a cycling valve which automatically closes when the oil in the chamber reaches a low level at the end of a degassing phase. After the cycling valve closes, the degassing chamber begins to fill with oil, and the rising oil level operates as a piston to expell the previously separated gas through a vent. When the oil completely fills the chamber, the vent closes and pressure within the chamber rises until a predetermined pressure is reached. The cycling valve then opens automatically, allowing the oil to again be withdrawn.

Abstract: The present invention relates to a double leaf filter head for drawing clear samples from a liquid to be analysed. The filter head is of especial use in drawing samples of phoshoric acid whose SO.sub.4 .sup.-.sup.- ion content is to be analysed by turbidimetric methods.

Abstract: Means for separation of water in the connecting duct of a saturated steam turbine. A spin generator with guide blades is built directly into the duct. Downstream behind the spin generator, there are provided annular openings in the connecting duct for removal of the water to surrounding water receiving chambers. The water receiving chambers are connected by a steam suction pipe to a zone of lower pressure in the central flow portion of the spin generator. A water vapor agglomerator is located in a bent section of the duct before the spin generator and consists of directional baffles. The water is first agglomerated and then spun out.

Abstract: An improved method and apparatus for degassing liquids which includes exposing a liquid containing entrained and dissolved gases to an improved degassing member. The degassing member is composed of a finely entwined porous material having physical properties causing the entrained and dissolved gases to coalesce near the surface of said member while allowing the degassed liquid to pass through said member.

Abstract: A filter unit for filtering lint from liquid washing machine effluent. The unit comprises a semi-rigid frame, preferably molded in plastic and consisting of a horizontal top rim, vertically depending frame elements, horizontally disposed bottom frame elements or portions thereof, and a mounting bracket which seats on one wall of a wash tub. A filter screen is mounted within the frame. The screen is a plastic mesh and forms closed sides and a bottom with an open mouth. A removable cap seats over the mouth and a washing machine drain hose extends through an aperture of predetermined size and shape into the screen within the frame.

Abstract: Milled screen units can be tack welded to existing pockets after the conventional screen has been removed or can be recessed into the top of modified pockets and tack welded. In both cases the construction of the screen unit permits minimal tack welding thus obviating the change in metallurgical structure normally present thereby reducing chemical fretting when used with active solutions and/or abrasive particles. The screen is formed from a cylinder in which the slits are milled. The sections are then cut from the cylinder and flattened so that the slits take up a cross sectional configuration having a narrow width on one side and gradually widening towards the other side thus preventing clogging during use.

Abstract: An in-line filter unit is provided for use in a circulating fluid system. Such a unit is made essentially into one piece to insure watertight. A debris reservoir is provided to store the debris removed from the fluid. A diffuser is placed in the line of fluid flow for preventing direct contact by the fluid entering the unit with the filter and for preventing damage to the filter.

Abstract: An oil separator in the output of an air compressor comprises a housing to which a mixture of compressed air and entrained oil is supplied through an inlet port which opens toward a separation unit removably inserted into the housing. The separation unit, comprising one or more filters adjoining an outlet port for the purified air, has a drain provided with an extractor for the forced exhaustion of oil retained in that unit; the extractor carried by the filter unit may be a nozzle, with an orifice that opens into the fluid flow issuing from the inlet port, or a pump whose impeller is driven by that fluid flow either upstream or downstream of the separation unit.

Abstract: A vertical upper inlet duct adapted to be connected to an upper section of a downspout or conductor leads downward through the upper wall of an open-ended horizontal box-shaped housing with a tapered bottom wall converging to a downwardly-tapered vertical outlet duct. The latter connects with a lower section of the downspout or conductor. A screen or grating is inserted in the box-shaped housing over the outlet therefrom, which may be cleaned of leaves or other water-borne trash collecting thereon by the user inserting his hand through either of the open ends of the housing. The screen itself is also similarly removable for cleaning.

Abstract: Method and apparatus for reacting nitric oxide with H.sub.2 in the presence of noble metal catalysts in which waste gas is obtained by separating the gas contained in a liquid medium flowing countercurrently to the bubbles in a counter-current bubble column. Preferably, only a portion of the separated gas is removed as waste gas, the remainder being recycled. The apparatus comprises a counter-current bubble column having a gas recycling circuit to permit the recycling of excess NO contained in the separated gas.

Abstract: Relatively dilute SO.sub.2 containing gases, such as tail gases from sulfuric acid plants, combustion gases from high sulfur fuels, and the like, are treated with a solvent, such as water, at approximately atmospheric pressures to dissolve the SO.sub.2, and the solution is then stripped at subatmospheric pressure with a gas, such as air, or a reducing gas if the SO.sub.2 is to be finally recovered as sulfur. The sub-atmospheric pressure may be attained by expansion of the stripping gas in a suitable gas expansion machine, and the stripped gas is then recompressed to a pressure, such as substantially atmospheric, at which final utilization of the stripped SO.sub.2 takes place.

Abstract: A filter cartridge assembly having a unitary cartridge body with a protuberance extending therefrom. The protuberance is designed to sealably fit into a fixed connection disposed between the inlet and outlet portions of the fluid stream. The protuberance is provided with a first sealing member in the form of a feathered edge seal adapted to seal the cartridge inlet and outlet fluid streams respectively. Another seal spaced beneath the feathered seal in the form of an "O" ring serves as a frictional seal between the top of the cartridge body and the fixed connection. An annular fluid stream passage formed between the interior wall surface of the fixed connection and the protuberance, allows the cartridge body to be urged into the connection without regard to orientation of inlet or outlet fluid stream passages.
