Patent number: 8661941Abstract: A hybrid drive system with first drive 11—especially a combustion engine—and second drive 12—especially an electric machine—for driving a transmission output shaft 20 of a transmission 10 for a vehicle is provided. The transmission 10 can include a first shiftable partial transmission 15 with a first main shaft 17, which is connectable by a first group of shiftable gear pairs 41/51, 45/52, 43/53, 44/54 to an intermediate shaft 28, and the first drive 11 is connectable to the first main shaft 17 of the first shiftable partial transmission 15. In addition, a second shiftable partial transmission 16 with a second main shaft 18, which is connectable by a second group of shiftable gear pairs 45/51, 46/52, 47/53, 48/54 to the intermediate shaft 28, can be included.Type: GrantFiled: April 20, 2011Date of Patent: March 4, 2014Assignee: FEV Motorentechnik GmbHInventors: Gereon Hellenbroich, Stefan Kohlhaas

Patent number: 8287913Abstract: An apparatus and method for the extraction of material from glands of arthropods. The apparatus comprises a container in which at least part of the glands are placed and a buffer solution at least partially immersing the glands. Gland material is collected in the material collection area of container. In use the material is released from glands into the buffer solution and sedimented at the bottom of the container. The method comprises: a first step of removing from a body of the arthropod the gland containing at least partially the material; a second step of making an opening in an epithelium of the gland; and a third step of placing the gland in a container at least partially immersed in a buffer solution such that the materials exit the glands and sediments in the material collection area of the container.Type: GrantFiled: May 28, 2008Date of Patent: October 16, 2012Assignee: Spin'Tec Engineering GmbHInventors: Michael Rheinnecker, Stefan Kohlhaas, Rolf Zimmat
