Abstract: A web-spreading device and a web-spreading process are provided. The web-spreading device, is provided whereby a first web strand being conveyed and a second web strand being conveyed next to the first web strand in a web-processing machine can be offset in parallel to one another in order to set a spread. A frame supports a first deflecting device (5r; 5r?), which forms a first deflection axis for the first web strand (Br), and a second deflecting device (6r; 6r?), which forms a second deflection axis for the first web strand (Br), which deflection axis is the next deflection axis for the first deflection axis in the conveying direction (F). The first web strand (Br) is offset in parallel by wrapping around the deflecting device (5r, 6r; 5r?, 6r?) and the spread (X; X+Y) is thus set in its entirety or in part. At least one of the deflecting devices (5r, 6r; 5r?, 6r?) is mounted adjustably along an adjustment path in the frame (2) in order to set the spread (X; X+Y).

Abstract: A ball and socket joint bellows seal is provided with a ball pivot pin with a connection piece, a bellows with an annular engagement surface with a sliding ring groove and a bellows seal element. The bellows seal element has a connection piece sealing face statically engaged with said connection piece, a radially extending sealing portion and a sliding ring portion connected to said radially extending sealing portion and extending into the sliding ring groove.

Abstract: The present invention pertains to a wiping and/or sealing element for sealing a piston (11) guided movably in a housing (10) with a seal held in a groove (21, 30). The present invention pertains, furthermore, to a process for sealing a movable piston (11) by means of a seal inserted into a groove (21, 30) and a clamping and/or support element with a piston (21), which is guided in a housing (10) such that it can be withdrawn and extended, wherein the piston (11) is sealed by means of a seal arranged in a groove (21). To achieve sealing of the piston (11) with a high sealing force for high liquid pressures at low friction, the wiping and/or sealing element according to the present invention as well as the clamping and/or support element according to the present invention are wherein the seal is a quad ring (22) with a square cross section.

Abstract: The invention concerns a chronograph-type watch provided with a movement (29) comprising: current time display means, measured time display means, a time base designed to regulate said display means, a control device (34, 40) for starting and stopping the measured time display means, a reset device for resetting the measured time display means when time measurement is over. The watch is provided with a case (10) for housing the movement (29) and comprising at least one slide (24) for controlling the control and reset devices. Said watch further comprises a locking device (32, 52) designed to co-operate with the control device (34, 40) to enable or disable it, and an actuating member (28, 44) designed to de accessible outside the case (10), for controlling device locking device (32, 52).
