Patent number: 11910760Abstract: A watering system (100) includes a watering robot (102). The watering robot (102) further includes an irrigation controller (110) configured to operate within a region (114). A connector portion (106) is coupled to the body (104), and is adapted to couple with the one or more water supplying units (116) to receive water therefrom. The watering system (100) is characterized in that a sensor (130) of the watering robot (102) detects the one more water supplying units (116) to selectively integrates therewith. An actuator (140) of the watering robot (102) at least partially lifts up the watering robot (102) with respect to a ground surface (120) of the region (114). The watering robot (102) automatically couples with the one or more water supplying units (116) through the connector portion (106), and the actuator (140) at least partially lifts up the watering robot (102) with respect to the ground surface (120).Type: GrantFiled: June 2, 2021Date of Patent: February 27, 2024Assignee: HUSQVARNA ABInventors: Christoph Schenk, Rainer Kaupp, Rudolf Pfau, Florian Soor

Patent number: 8235851Abstract: The invention relates to a tensioning or deflector pulley, in particular for the belt drive on an internal combustion engine, essentially comprising a plastic or steel running pulley, formed by an inner hub ring, an outer running ring and a pulley disc, connecting both rings to each other, with a radial roller bearing fixed in the hub ring of the running pulley, made up of an inner bearing ring and an outer bearing ring with a number of rolling bodies running between the bearing rings in channeled running tracks, retained at regular separations from each other by a bearing cage with a seal to both sides of the roller bodies, by means of which the cavity, formed between the bearing rings and designed as a grease reservoir, is sealed.Type: GrantFiled: May 10, 2007Date of Patent: August 7, 2012Assignee: Schaeffler Technologies AG & Co. KGInventors: Rainer Eidloth, Rainer Schenk, Georg Goppelt

Publication number: 20110306799Abstract: A method for the targeted execution of a reaction taking place alongside several competing chemical reactions is described, wherein the speeds of the competing reactions are set by the selection of the reaction conditions in such a way that the desired main reaction is not adversely affected. The invention further describes a new method for the oxidation of primary or secondary alcohols into aldehydes or ketones in the presence of dimethyl sulfoxide, a carboxylic acid anhydride or halogenide, and an amine in an organic solvent, in a continuous processing system (Moffatt-Swern oxidation).Type: ApplicationFiled: May 25, 2007Publication date: December 15, 2011Inventors: Rainer Schenk, Michael Küpper, Thomas Schwalbe

Patent number: 7448807Abstract: A seal for a pulley on a roller bearing includes a sealing cap which covers the front face of the roller bearing and is connected to a hub for externally enclosing the roller bearing. On the opposite side, the roller bearing has a sealing plate, which is likewise fixed to the hub and on the inner side interacts with a cylindrical section of the fixed housing.Type: GrantFiled: July 24, 2004Date of Patent: November 11, 2008Assignee: Schaeffler KGInventors: Rainer Schenk, Ralph Painta

Publication number: 20060188191Abstract: The present invention relates to a seal for a pulley (1) on a roller bearing. For this purpose a sealing cap (19a), which covers the front face of the roller bearing (2) and is connected to a hub (9), externally enclosing the roller bearing (2), is externally assigned to the roller bearing (2). On the opposite side the roller bearing (2) has a sealing plate (24a), which is likewise fixed to the hub (9) and on the inner side interacts with a cylindrical section (27) of the fixed housing (5).Type: ApplicationFiled: July 24, 2004Publication date: August 24, 2006Inventors: Rainer Schenk, Ralph Painta

Patent number: 7011593Abstract: A tensioning or deflection pulley for a belt drive includes a carrier and a track roller comprised of an inner ring, an outer ring, and a connecting assembly, including a wheel disk extending between the inner and outer rings, and a rib assembly disposed in both sides of the disk in circumferential spaced-apart relationship, for interconnecting the inner and outer rings. The track roller is supported on the carrier by a sealed rolling-contact bearing via a fastening screw. A first sealing element is connected to the track roller on a carrier-distal side, and a second cap-shaped sealing element is disposed between the carrier and the track roller and detachably secured to the inner ring of the track roller to thereby seal the track roller on both sides.Type: GrantFiled: September 2, 2004Date of Patent: March 14, 2006Assignee: Ina-Schaeffler KGInventors: Rainer Schenk, Aleksandar Lutkic
