Patent Number Title Of Patent Date Issued
5254303 Method and device for manufacturing molded bodies October 19, 1993
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
4822491 Process for transporting metal ions by means of microporous membranes April 18, 1989
A continuous high flow rate process for the transport of metal ions from a first aqueous liquid to a nonaqueous, water-immiscible liquid and therefrom to a second aqueous liquid. The nonaqueous liquid contains one or more complexing agents and is kept separated from the metal-ion-tra
4778569 Method of separation of liquid mixture of solution by porous separating wall October 18, 1988
In a method and arrangement for separating a liquid mixture or a solution by converting a portion of the liquid mixture or portion of a solvent of the solution into a vapor phase and subsequent condensation of the obtained vapor with a porous separating wall, the pores of the porous
4740104 Underground irrigation or watering of soil April 26, 1988
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 compo
4581236 Process and apparatus for reduction of alcohol by dialysis in fermented beverages April 8, 1986
Fermented beverages of a reduced alcohol contents are made by causing the fermented beverage having a normal alcohol contents as produced in the fermentation to flow along one face of a dialysis membrane at a pressure differential below 5.0 bar while simultaneously a dialysate liquid whi
4488929 Apparatus for the production of a continuous composite material December 18, 1984
A composite material consisting of at least three layers joined by welds, wherein, in order to prevent the intrusion of cold, as well as to improve the hand, the points of fusion do not join all layers, but in each case only a part thereof. It is especially suitable for the manufacture o
4484624 Apparatus for transferring heat by means of hollow filaments, and its use in various heating sys November 27, 1984
The invention relates to an apparatus for the transfer of heat by means of hollow filaments which extend in the form of a helix and/or a spiral and are provided in more than two layers. The apparatus may be made up of a multilayer winding. The outer diameter of the hollow filaments is
4440641 Hollow filament module and method and apparatus for production of the same April 3, 1984
A hollow filament module comprising an annular package of hollow filaments having a longitudinal axis, an axially extending flow channel of a hardened mass, and an outer mantle likewise of a hardened mass coaxial with said flow channel and radially outwardly arranged from the latter,
4343602 Gear wheel pump with reduced power requirement August 10, 1982
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 o
4305983 Thin walled tubing formed of a melt spinnable synthetic polymer and process for the manufacturin December 15, 1981
Thin walled tubing formed of a melt spinnable synthetic polymer having a flow-through cross-section amounting to 30 to 95% of the total tubular cross-section and a breaking elongation of less than 100% prepared by melt spinning a synthetic polymer so as to form a tube and then drawing of
4305626 Textile rollers December 15, 1981
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 roll
4289718 Mat material and method for making it September 15, 1981
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 co
4285898 Process for the manufacture of monofilaments August 25, 1981
The invention relates to a process for the manufacture of monofilaments for melt-spun synthetic polymers at high speeds. Lower spinning heights than conventional spinning applications are obtained by using the phenomena of natural yarn deflection.
4212915 Mat material of melt-spun polymeric filaments having discontinuous cavities July 15, 1980
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 co
