Patent number: 12142907Abstract: An overcurrent protection device is for protecting a load arranged in a DC grid. The load is coupled to a supply busbar, which is connectable to a supply potential of the DC grid, in the DC grid via the overcurrent protection device. The overcurrent protection device is designed to ascertain a current trigger value based upon a detected value of a current flowing through the overcurrent protection device and a trigger characteristic which is assigned to the load and is based on the current; compare the current trigger value with a threshold, and either trigger the overcurrent protection device or not, based upon the result of the comparison. The current is taken into consideration together with a first or a second factor in the trigger characteristic based upon the current direction.Type: GrantFiled: May 15, 2020Date of Patent: November 12, 2024Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Klaus Behringer, Wolfgang Feil, Peter Kaluza, Annemarie Lehmeier, Matthias Meier, Josef Burger, Thomas Bär

Patent number: 8814227Abstract: A latch secures an element such as a motor-vehicle headrest for movement relative to a support between a rest position and an advanced position. A pivotal lever can hold the element in the rest position. A spring pushes the element into the advanced position and presses it against the lever so as to apply a torque to the lever that presses a latch formation on the lever against a retractile latch part of an actuator. If the actuator retracts the part, the lever is released and the lever can pivot to allow the spring to move the element into the advanced position.Type: GrantFiled: February 23, 2009Date of Patent: August 26, 2014Assignee: Grammer AGInventors: Thomas Wallinger, Manfred Schenkl, Josef Meier, Eberhard Luber

Patent number: 7111901Abstract: A headrest for a motor vehicle seat is crash active in that it has a mechanism for automatically bringing the head-engaging member toward the head of the passenger in the case of a crash. This mechanism includes a slide guided on a pair of cylindrical members surrounded by springs and having a tooth-forming part of a return travel lock preventing return of the slide to its starting position. In that position a releasable coupling device has a primary coupling element engaged with a secondary coupling element which may be a hairpin-shaped bent wire.Type: GrantFiled: November 23, 2004Date of Patent: September 26, 2006Assignee: Grammar AGInventors: Manfred Schlierf, Josef Meier, Thomas Wallinger

Patent number: 5101067Abstract: The invention relates to a process for the preparation of pyridine-2,3-dicarboxylic acid esters using novel maleic acid esters as starting materials. In the process, in a first process step, 2,3-dihalomaleic acid esters are reacted with ammonia, or ammonium salts, with the exclusion of water at a temperature of at least 50.degree.0 C. to form novel 2-amino-3-halomaleic acid esters, and these are subsequently reacted further in a second process step with .alpha.,.beta.-unsaturated aldehydes, or ketones, in the presence of an acidic catalyst and acid-binding agents at a temperature of at least 50.degree. C. with heat being supplied until the pyridine-2,3-dicarboxylic acid esters have been formed. Pyridine-2,3-dicarboxylic acid esters of this type can be used for example, as intermediates for synthesis of herbicides based on imidazoline. The present invention also relates to novel 2-amino-3-halomaleic acid esters, which are useful for producing the final product pyyridine-2,3-dicarboxylic acid esters.Type: GrantFiled: December 21, 1990Date of Patent: March 31, 1992Assignee: Wacker-Chemie GmbHInventors: Josef Meier, Wolfgang Deinhammer, Konrad Krageloh

Patent number: 4252212Abstract: The muffler has an inner exhaust gas pipe and an outer casing. The inner pipe has a diameter which expands conically by about 6% between the input to the output ends of the casing. The inner pipe is also provided with longitudinal wall slots measuring about 30 mm by 2 mm and having a lip extending outwards toward the casing. The space between the inner pipe and the casing is filled with stainless steel wool. High frequencies of the vibrations in the exhaust gas are passed through the slots without appreciable gas flow through the slots, and their energy is dissipated in the wool. The wool is held in place by a metal strap wound helically on its edge about the inner pipe and welded to it. The casing is in two split halves which are held together against the inner pipe by a friction clamping element to permit differential expansion between the inner pipe and the casing.Type: GrantFiled: March 1, 1979Date of Patent: February 24, 1981Inventor: Josef Meier
