  • Patent number: 6634127
    Abstract: A picture frame with a frame (1, 2) has clamps (6, 7, 8, 9) for securing parts (3, 4, 5) inserted into the frame, such as a pane of glass, a picture, a rear wall, etc. The clamps (6, 7, 8, 9) have a bridge (14) and a spring clip (15). On the inside (12) of the frame (1, 2) a projection (17) is inserted into a recess (13). On the end of the bridge (14) there is another projection (16) which is inserted into a recess (11) on the back (10) of the frame (1, 2). On the end of the spring clip (15) there is a third projection (18) which is inserted into a recess (23) on the back (21) of the rear wall (5). This enables very adaptable and reliable mounting of the parts (3, 4, 5) in the frame (1).

  • Patent number: 6607464
    Abstract: A transmission, especially for wind power installations includes a planetary stage on the input side that is mounted upstream of at least one gear stage. The planetary stage includes at least two power-splitting planetary gears that are mounted in parallel. A differential gear that is mounted downstream of the power-splitting planetary gears compensates for an unequal load distribution between the individual planetary gears caused by their parallel disposition.

  • Patent number: 6462138
    Abstract: A process is described for reducing the residual monomer content in a liquid solution, mixture, melt, suspension or dispersion of a polymer by postpolymerization with addition of a redox initiator system at a reaction temperature appropriate to it and with an extremely short mixing time of the liquid system in the production reactor by metering—gradually, in portions or continuously—at least one of the redox initiator components required to initiate polymerization of the residual monomers over a period (metering time) which is from about 10 to 250 times the mixing time of the liquid system in said reactor.

  • Patent number: 5931388
    Abstract: A fuel injection valve for internal combustion engines, having a valve member guided axially displaceably in a bore of a valve body. On an end of the valve member toward the combustion chamber, a valve sealing face is disposed, with which the valve member cooperates with a valve seat face on the valve body to control an injection cross section. At least one valve spring that acts upon the valve member and is inserted into a spring chamber is provided in a valve retaining body that is braced axially against the valve body. The spring chamber is closed on one end remote from the combustion chamber by a lid. The lid is secured to the valve retaining body by a crimped connection.
