Title: Machine for polishing monumental stone - uses grinders on slide traversing beam which travels on rails and uses detectors to control movement
Inventor: PAGELOT GILBERT
IPC: B24B49/00
Filed: 1980-04-15
Abstract: The grinder is used to polish masonry slabs for monuments (10) and progressively covers the slab surface by reciprocal linear sweeps interposed by normal steps.

Title: Portable phase modulation duplex transceiver - has common aerial coupled to transmitter and receiver through isolating duplexer having cell structure
IPC: H04B1/50
Filed: 1980-07-24
Abstract: The appts. operates with the transmission and reception frequencies in the same bond and with the same separation as a semi-duplex system using a duplexer (6) to provide 50dB isolation between transmitter and receiver with only 1.3dB loss. The duplexer (6) is made of aluminium and is divided into four identical cells (7,8) closed at opposing ends by two brass plates.

Title: Clock signal regenerator for magnetic disc memory reader - has clock oscillator first locked in frequency and subsequently locked in phase at end of pre-synchronisation stage
Inventor: RICADR YVES
IPC: G11B20/14
Filed: 1980-12-31
Abstract: This process is used to regenerate clock signals when reading from a mass memory, e.g. a floppy magnetic disc, binary data which is coded as a series of space modulated pulses. Each series of data begins with a fixed number of phase alternations permitting a pre-synchronisation of a controlled oscillator used as regenerating clock whose output signal is controlled by the memorised signals. The controlled oscillator is first locked in frequency, and then, at the end of the pre-synchronisation stage, it is locked in phase to obtain the synchronisation. This double adjustment permits the generation of a reliable clock signal.

Title: Broken cutting tool detector for automatic machine tools - generates electrical signal when sensing probe travels over edge due to diminished tool profile
Inventor: BONTAZ YVES
IPC: B23Q17/09
Filed: 1981-02-11
Abstract: The device is fitted to an automatic machine tool and is more reliable than methods using a probe that makes electrical contact with the surface of the tool. An arm (5) fitted with a flexible extension (7) is moved between two angular positions (20,21) by a double acting pneumatic cylinder (9). The travel of the arm is normally stopped by the presence of the cutting tool. If the tool is broken or severely worn the arm is able to move to the lower position (21). An electromagnetic detector (13) senses the greater rotation of a 'D' shaped armature (11), causing the machine to be stopped. The armature cooperates with a magnetic proximity switch.
