The disclosure relates to a vacuum lifting arrangement comprising a vacuum pump, a valve arrangement, a support structure, and a flexible lifting tube comprising a suction foot. The vacuum pump is connected to the valve arrangement and to the flexible lifting tube. The valve arrangement is arranged to extend and retract the flexible lifting tube. The valve arrangement is arranged separate from the suction foot, between the vacuum pump and the suction foot. The disclosure also relates to a method of providing a vacuum lifting arrangement.

A gripping device for a part stacking system that according to one embodiment includes a plurality of supporting arms and a plurality of gripping elements attached to the supporting arms, at least some of said gripping elements being movable with respect to the respective supporting arm. Each supporting arm comprises at least one guiderail and each movable gripping element comprises a carriage movable in the corresponding guiderail. The static friction force between each carriage and the respective guiderail is such that the movable gripping elements are kept immobile with respect to the supporting arms by means of said static friction force during the part stacking process, and said movable gripping elements are positioned with respect to the respective supporting arm overcoming said static friction force.

The present invention relates to a lifting device for lifting and vertically, and possibly horizontally, replacing an object. The lifting device comprises a first unit (1) configured with one or more catching parts such as suction pads and a second unit (2) configured to control vertical and optionally horizontal position of the object. The second unit (2) comprises a first attachment position and a second attachment position and the first attachment position is fixed to a vertically extending part (3) of the first unit (1); the second attachment position is fixed to a sliding member (10) of the first unit (1) by a rigid joint configured to transfer all movements induced at the second attachment position by the second unit (2) to a sliding member (10) of the first unit configured to slide between two positions along a longitudinal member (11) of the first unit.

The invention concerns a lifting tube as well as a vacuum lifting device with such a lifting tube. The lifting tube has a tube wall extending about a lengthwise axis and enclosing a tube interior, while the lifting tube can be reversibly deformed along its lengthwise axis into an elongated configuration and, with reduction of the tube interior, a contracted configuration. The tube wall has a plurality of outer crease lines, along which the tube wall can buckle to produce the contracted configuration, while the outer crease lines run obliquely to each other so that, when deformed into the contracted configuration, the tube wall experiences a torsion about the lengthwise axis in some sections.

It is a major problem encountered in criminology studies, to match the fired bullet with the firearm. One of the acts being featured in the solution of this problem is to provide a holding appropriate for the fired bullet. This invention is about a vacuum powered bullet holder system to be used in forensic analysis of marks on fired bullet.

Battery gripper (12), for attracting by suction and handling starter batteries (26) of, in particular, motor vehicles, having a housing (56), in which a vacuum chamber which can be loaded with vacuum is provided and which has suction openings (84, 84) on the suction side thereof (54) which faces the starter battery to be attracted by suction, wherein the suction side is assigned a flexible lining (82) for contact with the starter battery, wherein the housing has a T-shaped cross section which runs parallel to the suction side, wherein the cross section has a bar section (64) and a web section (66) which extends transversely from the bar section, in such a way that the web section extends between the battery poles (68, 70) of the starter battery when the starter battery is attracted by suction to the battery gripper.

The present invention relates to a handling device (100) for handling foodstuff, comprising a suction cup (10) and a docking piece (30) supporting the suction cup, wherein the suction cup (10) is removably attached to the docking piece (30), wherein the docking piece (30) comprises a drive nozzle (32) inserted into the suction cup (10) attached to the docking piece (30) for ejecting a fluid from the drive nozzle (32) inside of the suction cup (10), and wherein the suction cup (10) comprises a drive opening (14) for receiving the drive nozzle (32) of the docking piece (30), an outlet nozzle (16) having at least one constriction which outlet nozzle (16) is aligned with the drive nozzle (32), so that the drive nozzle (32) and the outlet nozzle (16) cooperate to form an ejector, and a suction opening (12) for applying a suction force provided by the ejector to a surface of the foodstuff to be handled.
