Title: Multi-stage filter circuit tuning - uses computer controlled facility for point tuning of filters to compensate for prodn. differences
Inventor: MUELLER GUENTER DIPL ING
IPC: H03H3/007
Filed: 1976-09-04
Abstract: A method of tuning multi stage filters used in high frequency circuit applications allows compensation to be made for unavoidable differences due to manufacturing tolerances. A number of RC filter circuits are connected over coupling stages. The resulting output waveform indicates a range of phase errors at the particular resonant frequencies when compared with the ideal. A computer controlled tuning system has a computer (MR) that controls the frequency of a generator (G) coupled to the filter circuit (F). A display (BA) allows the difference between ideal and actual performance to be observed and an input (EG) allows operator control. The correction occurs on a point-to-point basis.

Title: Concrete test cube dimensions measurement - uses photoelectric sensors exposed to light source except where covered by cube
Inventor: LEBISCH HERMANN
IPC: G01B11/00
Filed: 1977-03-05
Abstract: The measuring system esp. for test cubes of concrete measures side length and hence cross-sectional area or volume.

Each surface has a sensor bar (12) below the top edge of the cube and parallel to the baseplate and one surface has a sensor bar perpendicular to the baseplate. Only certain of the sensors on each bar are covered by the cube face whose length is being measured. A light source (18) is positioned so that its light reaches all the sensors not covered by this cube face. The length of the face or its deviation from a set length is established in a measuring circuit from the number of sensors exposed to the light.
