Title: Identification system for transmission wires carrying digital signals - having constant pulse repetition frequency and phase, which periodically changes impedance
Inventor: DRUEGH PAUL DIPL PHYS
IPC: G01R31/02
Filed: 1979-04-11
Abstract: The system alters the reactance at a point in the wire being considered during the transmission of the digital signals in the signal path before the place under investigation. The digital signals at the place of investigation are examined for the occurrence of phase modulation of the appropriate period. In the case of double wires, the impedance of both wires is altered in opposition. The impedance is changed periodically by connecting a reactance to the wire concerned at a frequency chosen by taking into account the signal-to-noise ratio at the receiver. A phase-demodulator is used to detect phase modulation and has a bandpass filter at its output.

Title: Transport band for thermal fixer - has stippled surface with perforations for min. contact area
Inventor: HEIMBRECHT BERNHARD DIPL ING
IPC: G03G15/20
Filed: 1980-11-03
Abstract: The copy sheet is held on the transport band (1) by suction through a pattern of holes (2). A pattern of stipples (3) on the contact side holds the copy sheet out of contact with the band and provides a low thermal contact. This enables a low power thermal fixer to rapidly heat and fix the copy. The metal band with raised stipples ensures even thermal fixing and little chance of the copy sheets sticking to the band. The height and spacing of the stipples is related to the type of copy paper used. The low thermal loss enables a high throughput rate to be achieved with a low power fixer.
