Patent number: 5918485Abstract: A warp knitting machine comprises a jacquard guide bar (102) whose guides (7) are movable to and fro between two end stops (113 and 114). This motion is effected by setting members of a guide control. The end positions of the guides have a separation equal to two needle spaces. Additional strikers (115) and (116) are, at choice, made operative by the setting members (transducer 108) of a stop control. When one of the additional strikers is in an operative position, that striker holds the guide (7) in a central position. In particular, needle control and stop controls may operate with piezoelectric transducers. In this manner, it is possible to obtain an extremely large number of patterning possibilities.Type: GrantFiled: December 5, 1997Date of Patent: July 6, 1999Assignee: Karl Mayer Textilmachinenfabrik GmbHInventors: Joachim Fischer, Kresimir Mista

Patent number: 5905160Abstract: The epoxidation is carried out in a reaction system made of metal under conditions such that the inner surface area (S) of the reaction system exposed to the gaseous-phase part thereof and the amount of the reaction solution (V) in the reaction system satisfy the formula: 0<S/V.ltoreq.2 (m.sup.2 /m.sup.3). The epoxidation, otherwise, is carried out in a reaction vessel such that at least the inner surface thereof exposed to the gaseous-phase part thereof has been inactivated or in a reaction vessel such that at least the inner surface thereof exposed to the gaseous-phase part thereof has been inactivated. A hydroxy iminodisuccinic acid is produced by causing the epoxysuccinic acid which has been obtained as described above to react with L-aspartic acid. By this reaction, an epoxy compound can be produced with a high yield without inducing coloration by epoxidizing a corresponding ethylenic compound with hydrogen peroxide.Type: GrantFiled: October 30, 1996Date of Patent: May 18, 1999Assignee: Nippon Shokubai Co., Ltd.Inventors: Masatoshi Shimomura, Miaki Asakawa, Yuichi Kita

Patent number: 5897780Abstract: In order to treat water contaminated with warfare agents and containing less than 500 ppm of salt, a separation stage 10 is normally provided downstream of the reverse osmosis. In the separation stage, the untreated water is divided into residue and permeate. Warfare agents have the property of acting as softeners on the semi-permeable organic polymer membranes of separation stages. As a result of this, the warfare agents pass through the membranes of separation stages in increasing quantities once the latter have been in operation for a few hours. In order to improve the treatment of water contaminated with warfare agents, salt is added to the untreated water which, with a salt content of over 1000 ppm, is then drawn through the separation stage 10 down stream of the reverse osmosis stage. The invention is suitable for use with mobile facilities used for producing drinking water.Type: GrantFiled: June 18, 1997Date of Patent: April 27, 1999Assignee: Fed. Republic of Germany, Federal Defense MinistryInventors: Alexander Grabowski, Michael Dolle, Ingo Haser

Patent number: 5894743Abstract: A process and machine for the preparation of pile ware uses a single needle bedded warp knitting machine, having pile sinkers. During the swing-through of the guides subsequent to the underlap into the overlap position, first the ground threads and then the left pile threads, are laid to the rear of the needles, and run along these, with separation from each other. The pile sinkers are introduced into the space between the ground threads and the left pile threads, during or after the swing-through, and stay there until the knock-over of the stitch. The threads are provided to the guide bars in a one full/one empty order, only every second needle serving for stitch formation. The number of pile sinkers equals half of the number of needles. Right pile threads are provided which are overreached by the pile sinkers together with the ground threads laid about needles not serving for stitch formation and are then knocked over.Type: GrantFiled: November 10, 1997Date of Patent: April 20, 1999Assignee: Karl Mayer TextilmaschinenfabrikInventors: Jorg Bredemeyer, Horst Jager

Patent number: 5885921Abstract: There is provided a process for the preparation of a highly reactive hydrophobic silica capable of lipophilic binding of lipids present in aqueous media, in particular body fluids. The hydrocarbon substituted silica utilized in the first step of this process may be prepared from hydrophilic silica, suitably pyrogenic silica. This is then treated with a volatile hydrocarbon substituted silicon compound. The next step of the process comprises treating the substituted hydrophobic silica with an alcohol. In order to enable the thus produced material to selectively adsorb lipids in the presence of protein, to the substantial non absorption of the proteins (other than lipoproteins), a further step is carried out. This comprises treating with aqueous ammonia or amines wherein substituents on the amine nitrogen may be the same or different.Type: GrantFiled: October 25, 1996Date of Patent: March 23, 1999Assignee: Ligochem, Inc.Inventor: John Krupey

Patent number: 5860454Abstract: An electromagnetically-operating Jacquard control device has an electromagnet (1) with a magnetic core (3), an armature (8) and a limit stop (14) for each controlling element (16) to be controlled. The limit stop can optionally be brought into the movement path of a hook (18) attached to the controlling element (16). Two lovers (5, 11) are provided, the first bearing the armature (8) and the second bearing the limit stop (14). These two levers are coupled to one another with positive engagement such that the forces are transmitted substantially perpendicularly to the plane formed by the limit stop (14) and the swivel pin (12) of the second lever (11). This enables wear-related incorrect operation to be avoided.Type: GrantFiled: December 5, 1997Date of Patent: January 19, 1999Assignee: Karl Mayer Textilmachinenfabrik GmbHInventors: Kresimir Mista, Hans-Jurgen Hohne

Patent number: 5855782Abstract: The present invention is directed to an arrangement for the elimination of substances by means of a membrane filter wherein the use is foreseen both in the blood cleaning procedures as well as in chemical and biotechnological separation techniques. The fluid containing the substances is run through the primary side of the membrane filter and the secondary side is flowed through by a adsorptive suspension which contains the substance binding particles. A pump drives the adsorptive suspension through the secondary side of membrane filter and causes in this way locally differentiable positive and negative transmembrane pressure differences whereby a local fluid exchange occurs and by means of which the active substances come into contact with the particles. Since the volume of the adsorptive suspension in the secondary circuit is held constant, the mean transmembrane pressure does not alter.Type: GrantFiled: February 9, 1996Date of Patent: January 5, 1999Inventors: Dieter Falkenhagen, Heinrich Schima, Fritz Loth

Patent number: 5854306Abstract: There is provided a method and novel formulations for printing images on a latex rubber surface. An ink containing natural or synthetic rubber, a pigment dispersion, and an aromatically unsaturated solvent medium for said rubber is used. The stability of the image is improved providing to the rubber molecules of the ink, an agent, such as an aryl diisocyanate, that will form a tough, flexible, chemically resistant matrix between the rubber molecules of the ink, the base coat, where present and the latex surface. A base coat may be used upon the latex surface to anchor the printing ink thereto. This base coat can comprise a natural rubber in an aromatically unsaturated solvent and may also contain the aryl diisocyanate. The method may be improved by certain post printing steps such as heating and curing the printed product.Type: GrantFiled: July 8, 1997Date of Patent: December 29, 1998Assignee: Herbert GlattInventors: Henry Mattesky, James Gugger
