Abstract: A saw cable for a cable saw for cutting natural rock or stone, masonry or the like includes cutting beads provided with cutting grain, for example diamond, provided at intervals or spacings from each other on a metal cable. Spacer sleeves of castable or injection-moldable material are disposed between the cutting beads. The diameter of the spacer sleeves is smaller than the diameter of the cutting beads. The spacer sleeves (4) have annular lands (4'), the diameter of which is the same as the diameter of the cutting beads.

Abstract: A measuring apparatus such as a scale comprising a weighing platform module, an evaluation module including a microprocessor, and a connecting cable for operatively connecting the modules, the apparatus being operable in at least two (2) different operating modes such as a weighing mode, a calibration and adjustment mode, and a servicing and diagnosis mode, has a plug and socket connection between the modules which, when connected, sets the apparatus in a predetermined one of the operating modes, conveniently the weighing mode. The currently operative mode is automatically determined by the plugging in or unplugging of the connector cable with or without an intermediate plug. This ensures simple and substantially error-free operation of the apparatus.
