Patent number: 9370857Abstract: A pipe wrench or water pump wrench includes a clamp having a first shaft-like grip part and a handle having a second shaft-like grip part. A first jaw having a first gripping surface is disposed at one end of the clamp and a second jaw having a second gripping surface is disposed at one end of the handle. The second gripping surface is formed so as to be complementary to the first gripping surface. The jaws extend in a jaw gripping direction. The gripping surfaces form a first gripping recess. An adjusting mechanism having a toothed slot is disposed in the clamp. The toothed slot is curved in the jaw gripping direction. A pivot pin connects the clamp and the handle in a pivotable manner with respect to one another. The pivot pin is displaceable via the adjusting mechanism.Type: GrantFiled: June 18, 2012Date of Patent: June 21, 2016Assignee: ROTHENBERGER AGInventors: Norbert Guenther, Marco Theissen, Stefan Schultes

Publication number: 20150115539Abstract: The disclosure relates to an apparatus for sealing shafts, the apparatus comprising at least one device for positioning at least one first sealing means and a second sealing means on a shaft in a specified manner. At least the first sealing means has a partly elastic wall region for restricting a fluid passage out of a first region, in which a fluid is provided, into a second region, from which the shaft is sealed by the first region. The wall region forms an opening through which the shaft is guided, the diameter of the opening being variable dependent on the diameter of the shaft, and the second sealing means lies over the first sealing means so as to contact same at least in some regions in order to seal the fluid passage.Type: ApplicationFiled: April 26, 2013Publication date: April 30, 2015Inventors: Norbert Guenther, Guenther Eggert, Robert Engel, Toralf Genz

Publication number: 20100104898Abstract: The invention relates to a fuel cell system comprising a reformer for generating a reformate from a fuel and an oxidising agent, a fuel cell for converting the reformate into a depleted reformate and electric energy, and a recirculation conduit for partly returning the depleted reformate to the reformer. In this connection the invention is advantageously characterised in that a delivery device is provided by means of which the fuel as well as the depleted reformate from the recirculation conduit are supplyable to the reformer. The invention further relates to a method for operating such a fuel cell system.Type: ApplicationFiled: March 13, 2008Publication date: April 29, 2010Applicant: ENERDAY GMBHInventors: Norbert Guenther, Andreas Reinert, Stefan Kaeding, Björn Erik Mai

Publication number: 20090239110Abstract: The invention relates to a reformer for a fuel cell system for generating a reformate comprising a plurality of function units for treating the fuel, at least one function unit being adapted to a first type of fuel. In this arrangement the invention is characterized to advantage in that the function unit adapted to the first type of fuel can be releasably coupled to the reformer as a module by means of an interface which is also designed to couple a replacement function unit instead of the function unit adapted to the first type of fuel, the replacement function unit being adapted to a second type of fuel different from the first type of fuel. The invention relates furthermore to a function unit for such a reformer, to a fuel cell system having such a reformer and to a motor vehicle having such a fuel cell system.Type: ApplicationFiled: June 12, 2007Publication date: September 24, 2009Applicant: ENERDAY GMBHInventors: Matthias Boltze, Michael Rozumek, Stefan Käding, Andreas Lindermeir, Norbert Günther, Jeremy Lawrence, Andreas Reinert, Marco Mühlner, Stefan Kah

Publication number: 20090191434Abstract: The invention relates to a fuel cell system including a fuel cell stack (10), an afterburner (12) for combustion of exhaust gas emerging from the fuel cell stack and sited in an exhaust gas conduit of the afterburner a heat exchanger (16) in which cathode feed air (18) supplied to the fuel cell stack (10) can be heated. In accordance with the invention it is provided for that cathode feed air (20) can be supplied to the fuel cell stack (10) without being prior heated in the heat exchanger (16) and that the heat and temperature balance of the fuel cell stack (10) can be tweaked by the overall flow of the cathode feed air supplied as well as by the ratio of the proportions (18, 20) of the cathode feed air as heated in the heat exchanger and as not heated in the heat exchanger. The invention relates furthermore to a method of tweaking the heat and temperature balance of a fuel cell stack.Type: ApplicationFiled: July 5, 2007Publication date: July 30, 2009Applicant: ENERDAY GMBHInventors: Stefan Käding, Jeremy Lawrence, Norbert Günther, Su Zhou

Publication number: 20070084118Abstract: A reformer for reacting fuel (12) and oxidant (16, 18, 20) into reformate (22). The reformer has an oxidizing zone (24), a reforming zone (26) and an injection and mixture forming zone between the oxidizing zone (24) and the reforming zone (26). A mixture of fuel (12) and oxidant (16, 18, 20) is delivered to the oxidizing zone (24) and is delivered at least in part to the reforming zone (26) following at least partial oxidation of the fuel (12). Fuel (14) and heat (28) can be supplied to the reforming zone (26) in a method for reacting fuel (12) and oxidant (16, 18, 20) into reformate.Type: ApplicationFiled: December 16, 2004Publication date: April 19, 2007Applicant: Webasto AGInventors: Stefan Kaeding, Norbert Guenther

Patent number: 7112180Abstract: A below-knee orthotic device in which dorsal flexion and plantar flexion are enabled by a support spring connecting a lower leg sleeve and a foot sleeve. The support spring is clamped in the foot sleeve, so that a gap is formed between the heel part and the foot sleeve, wherein bending of the support spring in stepping direction is limited through a stop on the foot sleeve.Type: GrantFiled: April 23, 2002Date of Patent: September 26, 2006Assignee: F. Gottinger Orthopaedie-Technik GmbHInventor: Norbert Guenther
