To wind a cross wound bobbin, partic. with spun fibre yarn, the reciprocating motion to lay the yarn (16) crosswise has sections with only one stroke (24) which is smaller than the bobbin length (25). This reciprocating movement for a short period is overlaid by a total relatively slower forwards and backwards shift of the yarn guide eyelet (18) in the direction of the bobbin axis (21). The recipr...

PURPOSE:To detect a code matching at a high speed by permitting plural errors without increasing a circuit scale, in a code matching detection system in which the matching of an input code with a desired code is detected by permitting a mismatching element, even when the input code includes the mismatching element with the desired code. CONSTITUTION:A code mismatching detecting part 11 converts th...

The invention relates to a front ski-binding element which is intended to hold the end of a boot bearing on a ski. The element comprises a base (3), and a body (8) which is movable with respect to the base (3) parallel to a median longitudinal and vertical plane of the ski. Moreover, the body carries a member (15) for holding the front end of the boot. The body (8) and the base (3) are connected t...

The trailer (2) of an articulated road vehicle has a front axle proof-mounted and can be moved by the action of the towing vehicle (3) to be positioned along a guide path. The path is in the form of a wire (1) carrying a.c. signals that provide inductive capacity to sensors (6). The on-board microprocessor system agnerates sum and difference val-ues from the signals to detemine the angular positio...
