Title: Electronic article monitoring label
Inventor: BENGE EUGENE S
IPC: B32B37/20
Filed: 1990-08-03
Abstract: Permanent deactivation of labels used in an electronic article monitoring system involves a resonant circuit controllable by a first energy level contg. a spiral conductor with a number of conductor regions. A deactivation device arranged transversely above and bounding on at least a few regions contains a deactivation conductor and a normally non-conducting perforation sheet.

Title: Paper pulp smoothing - has oscillating materials at wet section of paper-making machine to prevent local fibre build=up
Inventor: STOLZ RUDOLF DR
IPC: D21F1/20
Filed: 1990-08-07
Abstract: To increase the quality of paper, in paper mfg.  electrical energy and active oscillating materials induce an oscillation in the paper material at the wet section of the papermaking machine. This reduces variations in the paper mass which could be formed by local fibre lumps. The active oscillating materials are pref. at the fourdrinier section of the papermaking machine, at a small gap from the fourdrinier, or in direct contact under it, or over it in the case of the double fourdrinier. The oscillating  materials are incorporated in or at the stock inlet, and are activated at different oscillating amplitudes and different frequencies. The active materials can be activated for oscillation  through another material for wear protection. ADVANTAGE - Designed esp. for printing papers, the method is not dependent on the speed of the papermaking machine, and the pulsed energy frequency can be varied to match the long fibre content without loss of fine materials.

Title: Demodulator for radio data signals - provides data pulse of one of two levels depending on sign of difference between phases of received signal and delayed signal
Inventor: HENZE WERNER
IPC: H04H40/18
Filed: 1992-02-19
Abstract: The system demodulates radio data signals transmitted by phase modulation of a suppressed carrier. The received carrier frequency signal is delayed by one half period of the bit period of the radio data signal. The received and the delayed carrier frequency signals are vectorially added. A rectangular signal is fed out from the result of the addition. The phase of this signal depends on the received and the delayed signals. A data pulse signal is fed out from the rectangular signal and the retrieved 57 kHz carrier. The data pulse has one of two levels depending on the sign of the measured phase difference. ADVANTAGE - No response time from phase control loops. Easily and inexpensively realised as integrated circuit and does not require expensive adapting processes. Only digital components required.
