Abstract: A method and device for removing at low pressures water vapor from a water vapor containing medium, particularly from a stripper steam for stripping edible oils at low pressures, the device comprising at least one absorption vessel with a feed pipe for the sulphuric acid and a nozzle for finely dividing the sulphuric acid, an outlet for discharging the same, a gas inlet and a gas outlet, a sulphuric acid recycling conduit, and a cooling member for removing heat from the sulphuric acid flowing through the recycling conduit.

Abstract: Supported semi-permeable membranes are prepared by coating a membrane-forming solution directly on a membrane support, said membrane support comprising a woven fabric selected from (1) a woven fabric made of mixed yarns and formed by employing as a part of the weft and/or warp yarns a yarn composed of a component soluble in a solvent used for forming the membrane-forming solution, (2) a woven fabric composed of a blended yarn including as one blend component fibers composed of a component soluble in a solvent used for forming the membrane-forming solution and (3) a woven fabric having its surface coated with a polymer soluble in a solvent used for forming the membrane-forming solution.

Abstract: In a rotary concentrator for continuous separation of a vehicle fluid and a concentrate of solids from an abrasive solids-containing fluid, a plurality of solids-detaining baffles and pockets are provided within the concentrator to collect deposits of the abrasive materials. This depositing of materials upon interior surfaces of the concentrator provides an autogenous, relatively stationary protective layer of abrasive material which protects those surfaces from the abrasive action of solids-containing material flowing past them during operation of the concentrator.

Abstract: A filter device particularly directed to the straining of materials for coating paper products which device is provided with a tapered baffle element to particularly aid in the back flushing of the filter to provide cleaning thereof and said baffle having a plurality of arcuately spaced fin members thereon for supporting of a filter element thereabout. This filter element is formed of a replaceable material having a plurality of apertures therethrough which material is normally non self supporting and which material gains its filtering support and positioning by the finned structure which will support the filtering element in both the normal filter operation and the back wash operation.

Abstract: An adsorptive device having at least one composite adsorptive element through which gas can pass comprising a bed of granular adsorptive carbon and a bed of fibrous adsorptive carbon.

Abstract: An extracorporeal filter having improved characteristics for the positive elimination of gas bubbles from blood streams. The top of the filter housing is sloped to a high point where there is positioned an air vent. The inlet for the blood is positioned substantially in the center of the top portion and extends past the plane of the top portion into the filter housing.

Abstract: This invention relates to apparatus for periodically automatically purging the contaminants from a filter unit of a compressed air system to reactivate the filtering medium in the filter unit during the time that an air compressor for supplying air under pressure to the system is operating unloaded or is stopped.

Abstract: A device for removing microemboli including microparticles and aggregates of various types including degenerated blood elements from whole blood or other transfusible materials, such as packed red cells and other blood components. The device has a casing with an interior chamber and is provided with externally-connectable flow inlet and flow outlet ports relative to the interior of the chamber, with a plurality of effective layers of microemboli-removing material positioned in the chamber and sealed to the inner periphery of the casing to require blood flow therethrough in travel of the blood from the flow inlet to the flow outlet.

Abstract: A filter having two plate-shaped cover members whose opposite major faces are formed with grooves are sealed to each other to form a chamber in which opposite surfaces of a layer of filtering material are engaged by the grooved major faces and bound the grooves. A conduit and an opening in one cover member constitute an inlet path, and an opening in the other cover member and another conduit constitute an outlet path for the fluid to be filtered and the filtered fluid respectively, both paths being transverse to the two major faces. The fluid entering the chamber is deflected at right angles from the inlet path into a direction parallel to the major faces, and the filtered fluid is correspondingly deflected into the outlet path to avoid erosion of the filtering material.

Abstract: A deep fat fryer trap receivable in the fryer well has imperforate trap portions extending along opposite margins of the bottom wall and an oil straining portion along a narrow medial portion of the bottom wall. The side walls have upper marginal edges closely fitting the well walls. Oil straining portions are also disposed in the side walls spaced upwardly from the bottom.

Abstract: A vacuum deaerator is provided with a plurality of low pressure chambers disposed in a multi-stage fashion. The pressures in the aforesaid low pressure chambers are so adjusted that the difference between the temperature at treated water which flows into respective low pressure chambers and the temperature in the low pressure chambers may be maintained constant.
