  • Patent number: 7757816
    Abstract: A transmission has a lubricant pump which is arranged in the interior of a transmission housing and which includes a rotor rotationally fixedly connected to a transmission shaft in a pump housing, with the pump housing being rotationally fixedly connected to the transmission housing and being sealed with respect to a cylindrical sealing surface of the transmission housing, and with the lubricant pump pumping into a pressure chamber which surrounds the transmission shaft and which is sealed with respect to the transmission shaft. To achieve a good seal and centration of the pump housing, the pump housing is sealed by means of a resilient ring with respect to the cylindrical sealing surface of the transmission housing, with the ring being received by an outer peripheral groove of the pump housing with radial clearance so that the pump housing can adjust itself in the radial direction.

  • Patent number: 7717010
    Abstract: The invention relates to a gearbox comprising a shift fork (4) that is displaced by an actuator using a shaft (2), whereby a rotational displacement of said shaft is translated into a displacement of the shift fork. To achieve an accurate displacement with minimum installation space, the gate (14) is configured on a sleeve (13) that is connected to the shift fork unit (4) in a rotationally fixed manner, said sleeve acting on the shift fork unit (4) in the direction of the displacement by means of a spring (24) and the shaft (2) runs through the sleeve (13), said shaft comprising a finger (11) that protrudes radially and co-operates with the gate. The shift fork unit (4) forms a housing (8) that surrounds the sleeve (13) and the spring accumulator (24) and that comprises bearing surfaces (34), by means of which the shift fork unit (4) is guided on the shaft (2) in the direction of the displacement.

  • Patent number: 7259257
    Abstract: The present invention relates to a new, particularly economical process for preparing particulate water-soluble cellulose derivatives. The process involves forming a feed composition of swollen and/or dissolved cellulose derivative, and water. The feed composition is contacted with a superheated gas mixture, in a sieve-free high rotational speed gas jet impact mill, and the cellulose derivative of the feed composition is converted into a solid state form of finely particulate particles. The superheated gas mixture, with which the feed composition is contacted, is selected from: (i) a superheated gaseous mixture of steam and an inert gas; and (ii) a superheated gas mixture of steam and air. The superheated gas mixture has a steam content of 40 wt. % to 99 wt. %, based on the total weight of the superheated gas mixture.

  • Patent number: 6509461
    Abstract: The present invention relates to a new, particularly economical process for producing particulate water-soluble cellulose derivatives. The process involves forming a feed composition of swollen and/or dissolved cellulose derivative, and water. The feed composition is contacted with a carrier and heat exchange gas, in a sieve-free high rotational speed gas jet impact mill, and the cellulose derivative of the feed composition is converted into a solid state form of finely particulate particles. The particulate cellulose derivative is then separated from the heat exchange gas and carrier gas, and optionally dried. The mill drying and the particulate cellulose derivative product are influenced by establishing a specific water content in the swollen and/or dissolved cellulose derivative.
