Publication number: 20240068523Abstract: A shaft-hub connection includes a shaft and a hub which engage with one another for conjoint rotation about an axis of rotation via a first toothing and a second toothing. The first toothing has a first toothing region and a second toothing region, wherein the first toothing region and the second toothing region are, as viewed in the circumferential direction (u), arranged offset by a dimension (d) in such a way that the first toothing region engages with the second toothing via front tooth flanks as viewed in the circumferential direction (u), and the second toothing region engages with the second toothing via rear tooth flanks as viewed in the circumferential direction (u).Type: ApplicationFiled: October 13, 2021Publication date: February 29, 2024Applicants: AUDI AG, Volkswagen AGInventors: Michael FRISCH, Johannes ALBL, Wolfgang HEISE

Patent number: 11708861Abstract: A spline connection having a hub with a toothing profile on the inner circumference, an axle journal having a toothing profile on an outer circumferential portion, a shoulder for axial support and/or abutment against the hub, and a tensioning device for axially bracing the axle journal with the hub. The hub has a constant toothing profile and the axle journal has a first portion and a second portion with different toothing profiles. The first portion is arranged on the insertion side to be further away from the shoulder than the second portion and has a constant toothing profile with play with respect to the toothing profile of the hub. The second portion is arranged on the shoulder side and has a toothing profile which has reduced tooth spaces compared with the first portion and which is play-free with respect to the toothing profile of the hub.Type: GrantFiled: September 7, 2021Date of Patent: July 25, 2023Inventors: Gregor Schaaf, Wolfgang Heise, Georg Schäfer, Paul Holzfuß

Patent number: 9791168Abstract: A heating block including a heating block body which receives/guides a liquid medium, an electric heating element arranged in the cavity for heating the medium via electric current, a semiconductor switch for controlling the electric current flowing through the heating element to control a heating power of the heating element, and a closure piece for closing an opening in the heating block body to the cavity element. The semiconductor switch is electrically and thermally conductively connected to the closure piece via first connection terminal to electrically connect the first connection terminal to the heating element via the closure piece, and to thermally connect the first connection terminal to the medium via the closure piece. The semiconductor switch is directly connected to a control board by a second connection terminal so that the semiconductor switch is spatially arranged and mechanically connected directly between the control board and the connection piece.Type: GrantFiled: July 3, 2013Date of Patent: October 17, 2017Assignee: Stiebel Eltron GmbH & Co. KGInventors: Martin Jansen, Wolfgang Heise

Patent number: 9709299Abstract: A heating block for use in a water heater for heating water, having a heating block body, in particular made of plastic, for forming a cavity for conducting the water and for receiving at least one heating element. The heating block body includes a first partial shell having a first sub-cavity and a second partial shell having a second sub-cavity. The first and the second partial shells are assembled in a joining region and form between them the cavity from the two sub-cavities. The joining region is not formed, at least partially, in a joining plane and/or the first and the second partial shells are welded together by the supply of heat via a medium, in particular, an essentially abrasion-free and/or vibration-free welding process, and/or the first partial cavity has a greater depth than the second partial cavity or vice versa.Type: GrantFiled: July 3, 2013Date of Patent: July 18, 2017Assignee: STIEBEL ELTRON GMBH & CO. KGInventors: Martin Jansen, Wolfgang Heise

Patent number: 5699741Abstract: A document printer, configured as a check printer, in a check dispenser (18) contains a reading device (30), disposed immovably in the delivery-side transport duct (10) of the printer, for registering a consecutive-running control marking imprinted on the reverse of the checks. The reading device makes use of the transport motion of the check, during its passage through the printer and delivery, for scanning purposes.Type: GrantFiled: September 25, 1995Date of Patent: December 23, 1997Assignee: Siemens Nixdorf Informationssysteme AktiengesellschaftInventors: Peter Schmidt, Wolfgang Heise, Bernhard Lappe

Patent number: 5087191Abstract: An embossing calender arrangement capable of embossing a thermoplastic plastics material film on either of its two major surfaces or both surfaces as desired, the embossing calender including two embossing roller sets. The roller sets are each mounted with their axes extending horizontally in one embodiment, in a common frame. The frame is horizontally displaceable beneath a film transfer arrangement by selectively displacing the frame and inserting the film into either one of the embossing nips defined in the roller sets or into both nips successively, the film can be embossed unilaterally on either of its two major surfaces or bilaterally without necessitating major adjustment of the arrangement.Type: GrantFiled: January 10, 1991Date of Patent: February 11, 1992Assignee: Hermann Berstorff Maschinenbau GmbHInventors: Wolfgang Heise, Kurt Trzynka, Andreas Kubik

Patent number: 4870256Abstract: A holding element for heating bars in industrial furnaces must be as flexible as possible so that it can accommodate the thermal expansion of the heating bars. Circular rings or circular-ring sectors provided with bores and made from a flexible graphite laminate plate are used for this purpose.Type: GrantFiled: June 3, 1988Date of Patent: September 26, 1989Assignee: Degussa AktiengesellschaftInventors: Wolfgang Heise, Georg Kell, Rolf Schuster

Patent number: 4784596Abstract: A calendering apparatus is disclosed which includes means for replacing a desired take-up roller from a take-up roller train. Displaceable, bifurcated carrier means are disposed on the embossing means forming part of the calender apparatus, which carriers can accommodate individual take-up rollers. The rollers are then moved out of the train by such carriers. The embossing means are also displaceable into a position in a lifting mechanism which can be used to collect the roller from the carrier.Type: GrantFiled: December 18, 1987Date of Patent: November 15, 1988Assignee: Hermann Berstorff Maschinenbau GmbHInventor: Wolfgang Heise

Patent number: 4699050Abstract: An apparatus for the clearance-free mounting of at least one of the rollers in the support column of a calender. The mounting is for producing plastics material films achieved by means of a roller bearing which is divided into three, a central section or ring and two laterally outer sections or rings in a direction transverse to the major axis of the roller journalled to rotate therein. Each bearing ring or section comprises an inner ring portion, at least one row of cylinder rollers, an outer ring portion and a bearing body portion. Pressure applicator means are provided for displacing the central section relative to the two laterally outer sections or rings in a direction towards and away from the roller journalled therein so as to eliminate play within the bearing. To eliminate the play between the bearing body and the calender support column, an additional pressure applicator means is provided which is incorporated in the calender support column.Type: GrantFiled: March 11, 1986Date of Patent: October 13, 1987Assignee: Hermann Berstorff Maschinenbau GmbHInventor: Wolfgang Heise

Patent number: 4655703Abstract: An embossing calender arrangement for thermoplastics material films which can be used for embossing either the top side or the underside of a film as desired comprises an embossing calender, the rollers of which are rotatably mounted in a frame. The frame, together with the calender is displaceable to and from a pivoting position by being suitably mounted and, when in such pivoting position, is pivotable.Type: GrantFiled: January 31, 1986Date of Patent: April 7, 1987Assignee: Hermann Berstorff Maschinenbau GmbHInventor: Wolfgang Heise
