摘要： A gear pump with reduced power requirement for conveying viscous liquids, especially thermoplastic fiber-forming polymer melts or a viscose spinning liquid, with intermeshed gear wheels rotatably mounted on parallel shafts while encased or circumscribed in a pump housing, i.e. enclosed on either side of the gear wheels and around the periphery thereof with an inlet opening for liquid feed means leading into the meshed point or area where the gear wheels disengage or become unmeshed and with an outlet opening for liquid discharge means leading away from the meshing point or area where the gear wheels engage or become meshed, the liquid thus being conveyed by the gear teeth from the inlet opening on one side of the meshing point around the outer portion of each gear to the outlet opening on the other side of the meshing point. A normal pressure-sealing or backflow-inhibiting radial gap is provided over at least a portion of each gear wheel periphery, i.e. between the top land or crown of the gear teeth and the opposing inner walls of the gear housing, preferably over a distance from the outlet opening of at least about three gear teeth or more. The remaining normally liquid-sealing gap spaces between the gears and the housing are enlarged according to the invention by means of axial recesses in the side faces of the gears and/or in the adjacent internal faces of the gear housing which extend in a plane perpendicular to the gear axes, and/or by means of radial recesses along the inner circular surfaces of the gear housing which extend around a major portion of each gear periphery, each of said recesses being formed circularly or as a sector of a circle, i.e. an arc-shaped recess defined herein as a segmental annulus which in the axial enlargement has the form of a flat annular sector of a circle or which in the radial enlargement has the form of an annular ring segment, and each of said recesses being arranged concentrically to the axis of its associated gear wheel. A gear pump of the invention is especially preferred which has only axial recesses or which has a combination of axial and radial recesses.

摘要： A mat material suitable for use for reinforcing plastics, as an upholstery material, filter material and various other purposes is made by melt spinning a synthetic polymeric material onto a moving embossed surface where the filaments become melt fused together at mutual points of contact. A gas or gas producing substance is mixed with the melt prior to extrusion to produce a plurality of adjacent, separate, discontinuous cavities in the filament.

摘要： The invention relates to a process for transferring metal ions from an aqueous liquid to a non-aqueous liquid and then to another aqueous liquid. The non-aqueous liquid contains one or more complexing agents and is kept separate from the aqueous liquid releasing metal ions by one or more microporous hydrophobic membrane(s). The non-aqueous liquid is circulated through two or more transfer zones in which the metal ions are taken up and released. The metal ions are released from the non-aqueous liquid into the second aqueous liquid by mechanical mixing of the two phases, followed by a mechanical separation process. The flow of metal ions obtained by this low-cost process is higher than in other processes. The process facilitates coupled co- and counter transport and may be used with advantage, inter alia, in the dressing of ores and in effluent treatment.
摘要翻译：本发明涉及将金属离子从水性液体转移到非水性液体，然后转移到另一种含水液体的方法。非水性液体含有一种或多种络合剂，并通过一个或多个微孔疏水膜与水释放金属离子的水分离。非水性液体通过两个或更多个转移区域循环，其中金属离子被吸收和释放。金属离子通过两相的机械混合从非水液体中释放到第二含水液体中，随后进行机械分离。通过这种低成本方法获得的金属离子的流动高于其它工艺。该方法有利于偶联和反运输，并且可以有利地用于矿石的修整和废水处理。

摘要： A high-speed winding apparatus for producing a filamentary spool package on a spool sleeve including spool holder means which engages the spool sleeve and which is rotatably mounted by means of a first set of anti-friction bearings onto a spool carrier which in turn is rotatably mounted by means of a second set of anti-friction bearings onto a support member. Drive means are provided to at least rotatably drive said spool holder means either directly or by a friction roll contacting the cylindrical surface of the spool package. The spool carrier is preferably also driven by a common or separate drive means at rotational speed proportionately slower than said spool holder means. The apparatus is especially useful for the take-up winding of filaments, threads, yarns or the like as employed in spin-drawing and high-speed spinning machines requiring linear winding speeds in excess of 5,000 meters/minute and spool revolutions of more than 30,000 rpm.

摘要： In a method and device for shaping thread-forming materials from a homogeneous isotropic or anisotropic, single or multiphase liquid multicomponent system, the liquid multicomponent system is forced through nozzle openings into a liquid which is under pressure. The liquid is moved in the direction of travel in a channel system composed of sections with constant and/or slightly tapering cross sections, and the flow rate of the liquid is increased accordingly.

摘要： System for the artificial underground irrigation or watering of soil, with flexible tubing of a porous material, characterized by tubes with a non-expanded porous inside structure. The tubes are obtained through extrusion of a homogeneous mixture of at least two components, one component a meltable polymer and the other component a liquid inert in relation to the polymer. Both components forming a binary system displaying in liquid aggregate state a range of complete miscibility and a range with a miscibility gap. Preferred parameters include an inside tubing wall surface with open pores and an outer wall surface, the degree of openings of which, calculated as fraction of open area, is reduced at least 20% in relation to the inside wall surface; open pores in the outer wall surface for the most part of a pore diameter of less than 4 .mu.m; tubes with a pore cavity volume of from 50-90%; tubes made of polypropylene; tubes made of glass fiber-reinforced polypropylene; tubing wall thickness of about 0.5 to 2.5 mm and outer diameter of about 2.5 to 25 mm. The tubing may be disposed within tubular-shaped sheaths of a matted web, composed of a plurality of fibers melt-spun from synthetic polymer, crossing over in places and fused together at the places of crossing. The sheaths may have a longitudinal grooved contour, and the matted web may be composed of polycaprolactam fibers with a diameter of about 0.2 to 1.5 mm. Couplings composed of the same material as the sheaths may be disposed at intersections thereof. The system is useful for the irrigation of grass, for irrigation in several layers, for permanent irrigation in arid zones, for the distribution of fertilizer, herbicides and/or pest control agents.

摘要： An aerodynamically supported roller bearing is disclosed, having means for connecting a compressed gas supply and using the compressed gas to bring the roller up to a desired speed. The design of the roller then permits the compressed gas supply to be reduced or turned off while the roller continues to be aerodynamically supported. Advantageously, some minimal compressed gas is continued through the roller to purge the roller of potential dust particles interfering with the operation of the roller.
