A trim operating lever device is disclosed which can downwardly or vertically swing a nozzle capable of adjusting the jet direction of jet water. When the trim operating lever is gripped with a finger of the hand which is gripping the steering handle, a lever of the lever lock means can be substantially simultaneously operated with the finger, to effect locking. Therefore, the number of operations by the left hand necessary for swinging the nozzle is reduced. Also, because the trim operating lever makes it possible to enlarge the operating force, the nozzle can be swung quickly.

A sliding door guide for motor vehicles, in particular vans and utility vehicles, includes an upper, lower and a central guide mechanism to hold the door in place. The door is flush with the side panel of the vehicle when closed and extends beyond the side of the side panel when open and can essentially be moved parallel to the side panel. The central guide mechanism includes a carriage and sliding rails. The sliding rails are arranged on the inside of the door, in which the carriage is hinge-mounted on a reversing lever and in turn the reversing lever is hinge-mounted on a pillar of the vehicle body. A first anchor is mounted in front of the carriage when seen in the direction of opening, and a second anchor is mounted in the side panel approximately half way along the path of opening. Together with the first anchor, this second anchor automatically activates a mechanical coupling or trap on reaching the corresponding opening positing, forming a further fixing point for the door-guide mechanism at the location of the second anchor.

A pipette for use with pipette tips in which a set metering volume is secured in that the locking body is arranged on the circumference of the annular cylindrical locking element when it is in the locking position. Through this, the transmission part which the locking element comprises on the outer circumference is held fast. The annular cylindrical locking element can be formed separately from a toothed ring for driving a counter mechanism. Thus, it is possible to perform the locking in arbitrary positions or in more selectable rotational positions than in the conventional locking equipment, where a locking element engages into the toothed ring for driving the counter mechanism.
