Publication number: 20200152406Abstract: The disclosure relates to an assembly for preloading a cable rotary-pendulum kinematic system, in which a rotational motion of a rotary body is converted into a translational motion of a winding body by winding cables, to which rotary body a torque may be applied. The assembly includes: a rotary body of a cable rotary-pendulum kinematic system, which rotary body is to be preloaded, may be rotated about the longitudinal axis thereof and is immovable in the direction of the longitudinal axis; at least one gas spring, which surrounds the rotary body and which may be compressed in the direction of the longitudinal axis; and primary cables, which force-lockingly connect the rotary body to the gas spring in such a way that a rotational motion of the rotary body causes compression of the gas spring, whereby the assembly is preloaded. The assembly has the advantage that no undesired oscillations occur in a cable rotary-pendulum kinematic system.Type: ApplicationFiled: April 18, 2018Publication date: May 14, 2020Inventors: Gerit Ebelsberger, Georg Bachmaier, Reinhard Freitag, Matthias Gerlich, Randolf Mock

Patent number: 9221058Abstract: Methods and arrangements for determining the fineness of a ground material in a mill are provided, wherein the acoustic spectrum of the mill during the grinding process is used for concluding the fineness. The mill comprises a drum in which the ground material is present during the grinding process, said drum being driven by a magnetic drive having at least one magnetic segment during the grinding process, so that a rotating magnetic field generated with the aid of the magnetic drive causes the drum to rotate. In order to determine the acoustic spectrum, a voltage induced in a coil of the magnetic segment is determined at least intermittently. On the basis of a model, using the detected time-dependent induced voltage, conclusions can be drawn about the acoustic spectrum and therefrom about the fineness.Type: GrantFiled: August 17, 2011Date of Patent: December 29, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Christoph Huber, Günter Lugert, Randolf Mock

Patent number: 8096522Abstract: A pressure regulator can be used particularly in a CNG-operated motor vehicle as an electronically controlled pressure reducer for maintaining the gas pressure constant on the injection valve used for filling the respective cylinder. The pressure regulator is composed of a control unit (1), a pressure reducer (3) that is controlled by the control unit (1), and a throttle (2) which connects the gas outlets (20, 40) of the working chamber (17) of the control unit (1) and the pressure reducer (3). A piezoelectric actuator (11) which affects the valve (21, 22) of an overflow device (14) makes it possible to specifically modify the gas pressure (P2) in the working chamber (17) of the control unit (1) and simultaneously influence the position of the valve (38, 39) of the overflow device (33) of the pressure reducer (3), thus allowing the output pressure (Pout) of the pressure reducer (3) to be adjusted to a predefined desired value.Type: GrantFiled: April 5, 2007Date of Patent: January 17, 2012Assignee: Siemens AktiengesellschaftInventors: Georg Bachmaier, Gerit Ebelsberger, Matthias Gerlich, Michael Höge, Erhard Magori, Randolf Mock, Harry Schüle, Stefan Treinies

Patent number: 6530273Abstract: A metering device and method for delivering fluid that employs a compensating element. The metering device has a housing defining a fluid chamber that contains a pressurized fluid. The-housing further encloses an actuating drive, a valve needle and a compensating element. The housing terminates at a housing opening for delivery of fluid to the outside of the housing. Fluid is delivered from the housing by moving the actuating drive which in turn displaces the valve needle in an opening direction. Upon displacement of the valve needle, the valve needle moves axially in the opening direction with little, if any, lift loss due to the compensating element. The compensating element further acts to compensate for shifting or movement of metering components due to external factors, such as varying thermal loads, aging effects, and settling effects.Type: GrantFiled: November 24, 1999Date of Patent: March 11, 2003Assignee: Siemens AktiengesellschaftInventors: Bernhard Gottlieb, Hans Meixner, Andreas Kappel, Randolf Mock
