Publication number: 20090229265Abstract: The invention relates to a method for converting thermal energy into mechanical work. Said method comprises the following steps which are performed as a cycle: A liquid work medium is fed from a supply reservoir (1) to a work container (3); the work medium in the work container (3) is heated by a first heat exchanger (5); a sub-amount of the work medium flows from the work container (3) to a pneumatic-hydraulic-converter (8), a hydraulic medium from the pneumatic-hydraulic-converter (8) is compressed in a work machine (9) in order to convert the hydraulic work of the hydraulic medium into mechanical work; the work medium from the pneumatic-hydraulic-converter (8) is fed back into the supply reservoir (1) and the hydraulic medium is returned into the pneumatic-hydraulic-converter (8). The invention also relates to a device for carrying out said method.Type: ApplicationFiled: May 24, 2007Publication date: September 17, 2009Inventors: Michael Mayer, Bernd Peter Pfeifer, Franz Peter Jegel, Steve Hargreaves

Patent number: 6570657Abstract: Surface plasmon resonance spectroscopy device includes an optical prism with a sample cell associated therewith and at least two sample detection areas that are provided with a thin metal coating selected for implementation of the SPR method and which contains, at least partially, surface-immobilized areas. Light is conducted via an optic fiber, collimated by a collimator with an aperture to a base surface of the prism, applied to an entrance of the optical prism. A multi adaptable diaphragm is provided between the collimator and the entrance surface. The diaphragm defines a path to the prism in a chronologically successive manner. Switching states are allocated to spectra corresponding to the switching states, whereby the spectra are obtained by detecting the light that leaves the prism through another collimator connected to another optic fiber applied to a polychromator wherein spectrally decomposed light is detected and evaluated by an evaluation and control unit.Type: GrantFiled: July 20, 2000Date of Patent: May 27, 2003Assignees: Institut Fuer Physikalische Hochtechnolgolie e.V., ANALYTIK Jena GmbH Analysenmessgeraete und LaboreinrichtungenInventors: Lutz Hoppe, Peter Pfeifer, Günter Schwotzer

Patent number: 4464822Abstract: In torsional vibration dampers and torsionally elastic coupling which comse torque-transmitting spring elements, which are clamped between spacers by an external clamping ring, which is elastically expanded for the installation of the spacers and spring elements. For a quick and efficient assembling of the dampers or couplings, the spacers alone are initially inserted into the clamping ring and are then subjected to radially outwardly directed pressure until the clamping ring has been expanded beyond the extent required to clamp the spring elements, which are subsequently inserted between the spacers, whereafter the spacers are relieved from pressure. This method can be carried out with the aid of a cylindrical assembling head, which is provided at its periphery with at least one radially movable pressure-applying member, which cooperates with at least one hydraulic cushion, which is adapted to be pressurized.Type: GrantFiled: September 29, 1982Date of Patent: August 14, 1984Assignee: Dr. Ing.
