Inventor: LETTKA ALEXANDER DR ING
IPC: G01H1/00
Filed: 1990-05-30
Abstract: The diagnosis of the mechanical properties of machines involves the use of the vibration signals of rotating parts and/or of the whole machine as the diagnostic signal.

Patent DE-4102417-A1 (DE)
Inventor: VIESSMANN HANS DR
IPC: F24H9/00
Filed: 1991-01-28
Abstract: The invention relates to a low temperature heating boiler for burning liquid or gaseous fuels, consisting of a water-bearing housing (10) which is passed through by at least one pipe (30) which delimits the combustion-bearing and/or gas-bearing space (20, 20') and in which a number of annular inserts (40) made of metal material are arranged, which cover the inner wall of the pipe. To achieve the aim that, for the purpose of preventing precipitation of condensation, the annular inserts, which are situated in the pipe and have a large mass and thus a high heat-absorption capacity, are to adapt automatically, with regard to their heat-conducting contact with the pipe, to the temperature conditions present at the offtake section, and in particular associated with the condition that this adaptation is to take place in the region of a direct heat conduction between the inserts and the water-cooled wall, at least the annular inserts (40) which are arranged in the offtake region are according to the invention formed from a metal material, the coefficient of expansion and heat conductivity of which are greater than those of the pipe (30), and these inserts (40), which are inserted into the pipe (30) with a loose sliding fit, are dimensioned in such a manner with regard to the inner diameter of the pipe that, as the heating of the inserts (40) increases, these bear against the pipe (30) with a press fit after the start phase. <IMAGE>

Patent DE-4131763-A1 (DE)
Inventor: NEUBERT ROLF DIPL ING
IPC: H02M7/48
Filed: 1991-09-24
Abstract: The invention relates to a method for reducing voltage oscillations of an intermediate-circuit centre connection (24) of a three-level converter which contains a plurality of three-level invertors (6, 7) which are each controlled by means of a basic-frequency clock. According to the invention, the three-level invertors (6, 7) are controlled such that, within a time interval in which, in terms of its magnitude, the amplitude of an output voltage is equal to half the intermediate-circuit voltage (Ud), a first three-level invertor (6) loads a first partial capacitor (26) and a second three-level invertor (7) loads a second partial capacitor (28) of the three-level intermediate circuit (4). A three-level converter is thus obtained, the voltage oscillations (especially the centre-point oscillations at the basic-frequency clock) of whose three-level intermediate circuit (4) at an intermediate-circuit centre connection (24) being reduced. <IMAGE>
