There is present on the other side of the web of material at least one countersurface, which can be displaced transvers...

The armature (2) has a cylindrical base (3). This goes into an actuator bolt (4) with a smaller cross-section than the base (3). The bolt (4) is axially movable in a guide sleeve (6) surrounded by the magnet coil (1). The end of the sleeve (6) is connected to a conical socket (7). The part (5) of the armature (2) going from the base (3) to the bolt (4) has a curved surface. The end of the base (3)...

A build-up drum for tyre prodn. and its intermediates has an adjustable dia. spreader ring for holding the tyre members (and the bead in partic.) centrally. An axially moving ring with taper on one side is mounted on the centre line; this ring can be pressed by conventional means into a correspondingly tapered spreader ring against a spring pressure; this spreader ring is made of a resilient mater...

In a guidance system for guiding an automated vehicle (2,3) around an area (18) such as a warehouse, a scanning laser beam from a source (14,15) mounted on the vehicle impinges upon reflectors (13) located round the area. Each reflector incorporates an optical code which identifies that reflector. Laser light reflected back to the vehicle from the reflectors is used to control the movement and hea...

A conveying apparatus of an IC card which is assembled in an IC card reader/writer includes upper and lower conveying belts (20, 30) to convey the IC card by sandwiching it. The upper and lower conveying belts are arranged so as to be deviated in the card conveying direction. A connector (60, 70) having contact members (61, 71) adapted to be come into contact with the contacts of the IC card is ar...

Watchdog signals (WD1, WD2) are fed to the input parts of counters, (3a, 3b) and the output state is maintained so long as there is no input on the reset part (R). A pulse sequence is fed to the inputs of AND gates (7a, 7b) connected to the reset part. The pulses are transmitted to the resets until a specific counter state is reached e.g. 23. When a watchdog signal line goes high the count cycle b...
