Patent number: 11073177Abstract: A rotational sliding bearing having a static part and a mobile part, each having a sub-shell with a sliding surface, each surface arranged within an angular range of max. 180° relative to the rotational axis in the direction of rotation of the bearing, and in a closed rest position, the sub-shells of all parts together form a bearing bush, the mobile part is arranged to pivot about a pivot axis for opening the bearing relative to the static part, such that a shaft mounted in the bearing is released in a release position, and the mobile part is shaped such that, based on the sliding surface position relative to the rotational axis, in the closed rest position, a translation of a shaft accommodated in the bearing is prevented transversely to the rotational axis and in the direction of the pivot axis of the mobile part or in the counter direction.Type: GrantFiled: January 20, 2017Date of Patent: July 27, 2021Assignee: AUROTEC GMBHInventors: Stefan Zikeli, Ernst Rauch

Patent number: 9555822Abstract: A transport device has a carriage and at least three wheels mounted at a minimum of two axles. One of the axles is a driven axle which carries only a single, centrally mounted, electrically driven wheel. A support unit is configured to accommodate an elongated load, such as a golf bag. A guide component on a control side has a handle area. When the cart is in the operational position, the drive axle at the carriage is on hand at the control side, and the support unit substantially protrudes in the direction of the control side laterally across the drive axle.Type: GrantFiled: October 11, 2012Date of Patent: January 31, 2017Assignee: Aurotec GmbHInventors: Ernst Rauch, Stefan Zikeli

Patent number: 5968434Abstract: To prepare cellulose mouldings, a solution of cellulose in a tertiary amine-oxide is moulded in a hot state and the moulded solution is introduced into a precipitation bath in order to precipitate the contained cellulose, wherein the hot moulded solution is cooled before introduction into the precipitation bath. Cooling occurs immediately after the moulding process and preferably consists of blowing air horizontally on to the cellulose moulding. The process according to the invention allows spinning of the cellulose solution with a high fiber density without the spun fibers sticking together after emerging from the spinneret. In spite of the high fiber density, it furthermore allows the use of a long air gap between the spinneret and the precipitation bath, by which means sufficient time is generated in the spinning process to affect the textile properties of the fibers by drawing at the die (FIG. 1).Type: GrantFiled: June 10, 1998Date of Patent: October 19, 1999Assignee: Lenzing AktiengesellschaftInventors: Stefan Zikeli, Ernst Rauch, Hermann Koberger, Friedrich Ecker, Hartmut Ruf, Raimund Jurkovic, Franz Schwenninger

Patent number: 5798125Abstract: Apparatus for the preparation of cellulose fibers from a solution of cellulose in a tertiary amine oxide includes a spinneret having a multiplicity of spinning holes arranged essentially in a ring-shape. An inlet for cooling gas is positioned in the center of the ring-shape arrangement of the spinning holes and immediately downstream of the spinning holes. The inlet comprises a tube having a baffle plate at one end.Type: GrantFiled: June 6, 1995Date of Patent: August 25, 1998Assignee: Lenzing AktiengesellschaftInventors: Stefan Zikeli, Ernst Rauch, Hermann Koberger, Friedrich Ecker, Hartmut Ruf, Raimund Jurkovic, Franz Schwenninger

Patent number: 5650112Abstract: The spinneret according to the invention is especially suitable for spinning cellulose solutions and has a die body which is essentially rotationally symmetrical having an inlet in its centre for cooling gas, an inlet for cellulose solutions, an annular deep-drawn spinning insert of precious metal with spinning holes wherein the spinning insert is designed pan-shaped in cross-section, and a baffle plate to deflect the cooling gas stream through the cellulose filaments which are extruded from the spinning holes, so that the cooling gas stream strikes the extruded cellulose filaments essentially at right angles. The spinning holes in the spinning insert are uniformly spaced from one another.Type: GrantFiled: March 29, 1994Date of Patent: July 22, 1997Assignee: Lenzing AktiengesellschaftInventors: Stefan Zikeli, Friedrich Ecker, Ernst Rauch

Patent number: 5607639Abstract: Method for the preparation of cellulose sheet by extrusion of a heated solution of cellulose in a tertiary amine-oxide, which method includes using an extrusion die with an extrusion orifice, characterised in that, immediately below the extrusion orifice there is provided an inlet for cooling gas to cool the extruded sheet. The method according to the invention is especially suitable for the preparation of cellulose tubular films.Type: GrantFiled: March 31, 1994Date of Patent: March 4, 1997Assignee: Lenzing AktiengesellschaftInventors: Stefan Zikeli, Friedrich Ecker, Ernst Rauch, Klaus Renner, Anton Sch onberg

Patent number: 4629867Abstract: There is disclosed a heated roll for the thermal treatment of formed products. It includes a driven hollow shaft and a hollow roll body of a circular-ring-shaped cross section and closed on all sides to accommodate a heat transfer medium. Power supply lines for heating elements as well as electric wires of temperature probes are led through the hollow shaft. In order to provide a heated roll to be used without problems both in the low-temperature range and in the high-temperature range up to about 600.degree. C. and to reach a uniform temperature profile over the total operation surface of the roll outer shell and a long service life of the heat transfer medium, without excessive temperature prevailing at the bearings of the driving shaft, and to provide for an easy repair, the hollow shaft is connected with the roll body by a hub. One or several saline compound(s) or (a) low-melting metal(s) or metal alloy(s) are contained in the interior of the hollow roll body.Type: GrantFiled: March 25, 1985Date of Patent: December 16, 1986Assignee: Lenzing AktiengesellschaftInventors: Josef Baumgartinger, Ernst Rauch, Haio Harms, Adalbert Wimmer
