Title: Paper sheet thickness measuring appts. - measures gap between rollers using deflection of movable roller carrier over light barrier
Inventor: MUNZ ROLF
IPC: B42C1/12
Filed: 1991-08-01
Abstract: The appts. measures the thickness of paper sheets (31,32) passing through rollers, taking the distance between the rollers (20,21) as a measure of the sheet thickness. The gap is measured by a light barrier device (33) whose output signals are summed until the sum of all generated gap widths have reached a defined thickness. One roller remains fixed (20) whilst the other (21) can move on a roller carrier (22) perpendicularly w.r.t. the paper transport direction (30). The carrier top is formed as a thin finger which displaces into the light barrier during measuring. An alternative measuring appts. may use mechanical gearing to displace a pointer on a given scale to indicte paper thickness. USE - To measure thickness of paper stack whose individual sheets pass successively through roller gap.

Patent DE-4135977-A1 (DE)
IPC: H03M7/42
Filed: 1991-10-31
Abstract: A process is disclosed for simultaneously transmitting signals from N-signal sources over a corresponding number of transmission channels. The individual signals are subdivided into blocks and the blocks are converted into spectral coefficients by transformation or filtering, and the latter are then subjected to a data reduction process. The invention is characterized in that the blocks belonging to the individual signals are subdivided into section. The momentary sections of all signals are processed together, the admissible disturbance is determined for each section by using a perception-specific model and the momentarily required total transmission capacity is calculated. The allocation of the maximum available transmission capacity for each individual signal is calculated from the total available transmission capacity and the total momentarily required transmission capacity. Each individual signal is coded and transmitted with the thus determined capacity.

Title: Sound system with subtracting digital filter in signal path - varies transfer function to improve system stability against feedback and increases acoustic output power
Inventor: GOERTZ ANSELM DIPL ING
IPC: H04R3/02
Filed: 1992-10-23
Abstract: The digital filter is inserted in the signal path of the system via analog to digital and digital to analog converters. Thus, the filter forms its own feed-back loop. In this feedback path, an FIR filter is used for precisely reproducing the complex frequency dependent loop transfer function. The filter coefficients are determined by a single measurement or are continually updated by an automatic measuring process. Thus, signal parts which have already passed through the loop once are subtracted from the signal. ADVANTAGE - Provides high feedback stability at all frequencies.
