Abstract: ABSTRACT OF THE DISCLOSURE      A disc refiner for pulp has a housing defining a chamber with an inlet and an outlet, three coaxial discs mounted in the chamber, and a shaft which rotates the central disc and extends with clearance through a large opening in one of the outer discs. The other outer disc is adjustable axially toward and away from the cen-tral disc and the central disc is movable axially of the shaft be-tween the two outer discs.  The stock enters via inlet and passes through the opening of the one outer disc. A portion of stock there-upon passes radially outwardly between the one outer disc and the central disc to be comminuted by ribs on the adjacent surfaces of the one outer disc and the central disc.  The remaining portion of stock flows through several relatively large openings of the central disc and thereupon radially outwardly toward the outlet by passing between ribs provided on the neighboring surfaces of the central disc and the other outer disc.  Each of the discs is a one-piece body.

Abstract: ABSTRACT OF THE DISCLOSURE: A process for continuous production of polyamides by continuous transport of a mixture or one or more lactams and from 1 to 15% and preferably from 3 to 8% of water and optionally other polyamide-forming compounds such as the salts of dicarboxylic acids and diamines or aminocarboxylic acids through a number of reaction zones under polyamide-forming conditions, said mixture of starting materials being heated in a first reaction zone to temperatures of from 210° to 330°C and preferably from 220° to 280°C, whereupon the polycondensation mixture is adiabatically vented in a further reaction zone and is then polymerized to completion in yet another reaction stage to form high molecular weight polyamides. The process is characterized in that (a) the mixture of starting materials is heated in the first reaction zone at  pressures which are above the respective vapor  pressures of the starting materials and prevent the formation of a vapor  phase, said heating being effected for from 5 minutes to 2 hours and pre-ferably from 10 minutes to 1 hour until a conversion of at least 70% and preferably 80% has been reached; (b) the polycondensation mixture is vented in the second zone to pres-sures of from 1 to 11 bars and preferably from 1 to 6 bars and is then immediately heated in a third reaction zone, preferably together with the steam formed during adiabatic venting, with the application of heat and evaporation of the major portion of the water at the said pressure obtained by venting or a lower pressure, said heating be-ing carried out for less than 10 minutes and preferably less than 5 minutes at temperatures of from 250° to 350°C and preferably from 260° to 280°C, whereupon (c) the polymerization mixture is separated from the steam in a fourth reaction zone and is polymerized to completion in a further reaction stage to form high molecular weight polyamides.

Abstract: ABSTRACT OF THE DISCLOSURE     Liquid edible oil is produced from palm oil or similar oils and fats.  The fatty acid residues are redistributed between two batches of the starting oil by transesterification with (C1-C3)-alkanol esters of fatty acids.  One batch is reacted with unsaturated fatty acid esters (first transesterification) and is thereby enriched with unsaturated fatty acid radicals, while the other batch is reacted with saturated esters (second transesteri-fication) and is thereby enriched with saturated fatty acid radi-cals.  In both transesterifications a mixture of saturated and unsaturated fatty acid esters is obtained, which is fractionated by vacuum distillation.  The saturated esters obtained from the first transesterification are fed into the second one and, con-versely, the unsaturated esters obtained from the second transes-terification are fed into the first one.

Abstract: ABSTRACT OF THE DISCLOSURE           A single tube surface operated pump is provided herein, including a piston reciprocally mounted in a cylinder for alternate-ly opening and closing a lateral fluid delivery port and for generating a sonic pressure wave by impacting a column of fluid in a metallic tube extending from the cylinder to a remote pumping mechanism located in communication with the fluid to be pumped.          The piston is especially configured with a central recess in the face thereof so that the sonic pressure waves generated thereby will move toward the pumping mechanism is a spiral-like motion against the inner wall of the metallic tube and are reflected off of the pumping mechanism into a central column which travels back toward the cylinder and causes the fluid to be pumped to move in that same direction.  Thus, by broad aspects of this invention, the sound pressure wave is generated by the impact of the end face of the aforesaid piston having the specially shaped recess or depression therein with the liquid.  Such generated pressure wave; is used to move a column of liquid upwardly to the ground surface from an underground level.

Abstract: Abstract of the Disclosure Disclosed is an improved apparatus for applying a uniform electro-static charge to a predetermined portion of an electrophotographic film.  The apparatus includes a corona generation source and a mask framing the predeter-mined portion of the film.  The improvement consists of an electrically con-ductive surface surrounding the frame opening of the mask and spaced from the surface of the film and a capacitor interconnecting the electrically conduc-tive surface with ground.  The electrically conductive surface on the mask develops a voltage close to that of the surface potential of the film during corona charging so that very little charge field discontinuity exists between the mask and the film, thereby permitting uniform electrostatic charging of the film up to the edges of the portion being charged.

Abstract: MICROWAVE HEATING APPARATUS          Abstract of the Disclosure Microwave heating apparatus employing at least one surface waveguide which is provided in a lower portion of the apparatus below an article to  be heated receives microwave output, directly or via a tubular waveguide, from an oscillator, and acts to concentrate microwave energy in a specific region of the apparatus, whereby heating is rendered more efficient and unevenness of heating in the vertical plane is avoided.          For improved evenness of heating in the horizontal plane the surface waveguide may be rotated either by a separate drive mechanism or by air supplied to cool the oscillator, or the article to be heated may be rotated or moved reciprocally while the surface waveguide is moving or is stationary.  The improved concentration of microwave energy permits greater economy, and offers a particular advantage for producing a highly baked or hardened outer surface without overheating of other portions of the article being heated.

Abstract: ABSTRACT OF THE DISCLOSURE    This invention relates to small lightweight hemodialyzers having a high surface area to blood priming volume. Previously considerable dif-ficulty had been experienced in the production of small lightweight hemodialyzers, particularly with regard to obtaining consistently good ultrafiltration rates, high wet rupture strength, absence of leakage during clinical use, and absence of torn membranes during manufacturing. These and other difficulties of the prior art have been overcome according to the present invention. According to the invention, there is provided a hemodialyzer in which a sealant anchors the edges of a plurality of generally planar semipermeable membranes to a generally rigid case. The moisture content of the membranes is maintained at approximately a constant value so as to prevent stress from being built up in the hemodialyzer due to changes in the dimensions of the anchored membranes with changes in moisture content. A stack of semipermeable membrane material is confined between wedge blocks within the hemodialyzer case. The wedge blocks permit the hemodialyzer to be assembled without placing shearing stresses on the membrane. Also, by trapping the last pleats of the membrane between the case and the outer surfaces of the wedge blocks the last pleats are easily encapsulated with sealant and thus sealed.
