  • Patent number: 10940009
    Abstract: The invention relates to a joint socket for a joint endoprosthesis, in particular in the form of a hip joint socket for a hip joint endoprosthesis. The joint socket has the form or substantially the form of a section of a hollow-spherical shell. The joint socket comprises a socket wall, in which socket wall at least one through-opening is formed. The through-opening is closed with a closure element. The closure element is formed as one piece with the socket wall. At least one predetermined breaking point is formed between the closure element and the socket wall. The at least one predetermined breaking point is irreversibly destroyable for removing the closure element from the socket wall. The joint socket comprises at least one connecting device for force- and/or form-fittingly connecting the closure element removed from the socket wall to the socket wall in a connecting position.

  • Patent number: 9670836
    Abstract: A drive unit for a motor vehicle that has a combustion machine having an internal combustion engine (10) as well as an exhaust gas system via which exhaust gas can be discharged from the internal combustion engine (10), and has a cyclic device that can be used to convert the thermal energy contained in the exhaust gas into mechanical work in a clockwise thermodynamic cycle, whereby the cycle comprises a heat transfer from the exhaust gas to a working medium in a first heat exchange device, as a result of which the temperature and/or the pressure of the working medium is increased, comprises an expansion of the working medium in an expansion device (30) for generating the mechanical work, and comprises a heat transfer from the working medium to a cooling medium in a second heat exchange device.

  • Patent number: 9458752
    Abstract: A heat exchange device having a first media channel for a first medium and a second media channel for a second medium is further refined in that, in at least one section of the heat exchange device, a third media channel for a transfer medium is arranged between the first media channel and the second media channel, so that the heat transfer from the first medium to the second medium takes place via the transfer medium.

  • Patent number: 8454611
    Abstract: A modular prosthesis rasp is provided, having a rasp body with a rasp main body and at least one modular rasp body part connectable to the main body. The rasp main body has a receptacle for receiving the at least one rasp body part. An outer contour is defined by the rasp main body and the at least one rasp body part. The rasp body part receptacle extends from an indentation, defining a distal end of the receptacle, on a lateral side of the rasp main body to a proximal end thereof. A first tangential plane of the lateral side of the outer contour in the region of the indentation and a second tangential plane at a rasp body part contact surface, in the region of the distal end of the receptacle include an indentation angle of less than 85°.

  • Publication number: 20110160733
    Abstract: A modular prosthesis rasp comprises a rasp body having a rasp main body and at least one modular rasp body part connectable to the rasp main body. The rasp main body comprises a rasp body part receptacle for receiving the at least one rasp body part in a connected position in which the rasp main body and the at least one rasp body part are connected to each other, and in which the rasp body defines an outer contour defined partly by the rasp main body and partly by the at least one rasp body part. The rasp body part receptacle extends from an indentation, defining a distal end of the rasp body part receptacle, on a lateral side of the rasp main body to a proximal end of the rasp main body.
