Abstract: The aim of the invention is to provide an improved interferometer which does not require a drive mechanism for moving a reference surface or a measuring object for tuning same interferometer and which can be tuned virtually without vibrations, thus avoiding inaccurate measurements. To this end, the interferometer (10) comprises at least one light source, a reference surface (40), a measuring object (50) and at least one beam splitter (30). For tuning to be vibration-free, the interferometer (10) further comprises a device (60, 70) for polarizing the beams to be interfered in such a way that at the output of the interferometer (10) the states of polarization of said beams differ from each other, as well as an analyzer (80) positioned at said output of the interferometer (10), the state of polarization of which analyzer can be altered in a predefined manner. In accordance with its state of polarization, said analyzer introduces a defined Pancharatnam phase into the beams to be interfered so as to tune the interferometer (10).
Patent DE-19723483-A1 (DE)
Inventor: CHALOUPKA HEINZ PROF DR
IPC: H01P3/08
Filed: 1997-06-04
Abstract: The invention relates to a device for conducting high-frequency signals having a superconducting layer, a dielectric layer, and a second superconducting layer. The layers are arranged on top of each other in such a way that the dielectric layer is situated between the two superconducting layers. The lateral dimensions of the dielectric layer are substantially smaller than those of the superconducting layers and determine the current density distribution in the device. With this inventive device, excessively high current density in the edge area of a microstrip can be avoided, which would otherwise reduce the load bearing capacity. This results in a high frequency component with a high load capacity.

Title: Method for regulating temperature of coolant in combustion engines
Inventor: HELDBERG CARSTEN DIPL ING
IPC: G05D23/275
Filed: 1997-07-01
Abstract: With the aid of a thermostat valve, the flow of the coolant can be regulated by a motor cooler, whereby an immediate activation of the valve by the temperature of the coolant at the valve, as well as an activation controlled by performance characteristics of the valve is provided. The immediate activation is only carried out when the other activation is out of operation. The valve has a throughlet for the coolant which can be closed by a safety valve. The safety valve uses an element whose shape reacts immediately to a change in temperature of the coolant. The valve hence closes on a prespecified temperature being exceeded.
