Abstract: The invention relates to a liquid handling apparatus for transferring liquid into and out of containers that are arranged in a substantially horizontal plane that is spanned by an X axis and a Y axis standing perpendicular to the X axis in the direction of a substantially vertical Z axis standing perpendicular to this plane. The liquid handling apparatus comprises an X slide which is travelable in the direction of the X axis and at which an arm having a Y slide is provided that is travelable in the direction of the Y axis and that is optionally configured for attaching at least one Z slide travelable in the Z axis. An X drive motor serves for driving the X slide via an X force transmission means and a Y drive motor serves for driving the Y slide via a Y force transmission means. Both motors are in fixed positions.

Abstract: A connecting system connects two fluid-conducting components, such as first and second tubes, or a tube and a connecting part, or first and second pipes. The connecting system includes: a flange of a first component set back from a free end region of the first component; a flange of a second component formed at or behind a free end region of the second component; a securing device that engages a sleeve arranged at the second component so as to axially secure and align the first and second components with respect to one another; and a jacket that at least regionally covers the first component, the second component, and the securing device.

Abstract: Disclosed is a tightening tool for a screw element, having a tool receptacle and an associated line. A coupling part is provided, which is formed at a free end for engaging with the tool receptacle in a form-closed manner and transitions into a handle or can be coupled to a handle at the other end. The coupling part has an interior and at least one lateral opening for inserting or leading out the line at least at the free end of the coupling part. The interior and the opening extend to the free end and are open there. The invention further relates to a coupling part and to a screw element.

Abstract: The present invention relates to a connecting system for connecting two fluid-conducting components, such as a first and a second tube or a tube and a connecting part or a first and a second pipe, the one component cooperating with the other component. The invention further relates to a method for producing such a connecting system.

Abstract: A screw element for fastening an article to a counter-piece, including a first part rotatable by hand or with a tool and a second part provided with a thread, wherein the first part and the second part can be rotated relative to one another about a longitudinal axis of the screw element, but can be held axially to one another via a connection point, as well as being composed of an installation limiting a torque transferred from the first part to the second part, the installation having at least one ramp part which can rotate with the first part or with the second part in a direction in parallel to the longitudinal axis of the screw element with respect to a spring bias and cooperating with ratchet noses of the respective other one of the first part or the second part.

Abstract: A screwable element (10) for fastening an object, in the form of a plastic conduit for example, to a counterpiece such as a connection to another conduit or a device connection, consists of a first part (14) rotatable manually or with a tool, and a second part (16) furnished with a threaded portion (15), wherein the first and second parts are rotatable relative to one another about the longitudinal axis (18) of the screwable element, but can be fixed to one another axially via a connection point (20), and a unit (24, 26) limiting the torque that can be transmitted from the first part onto the second part. Said unit comprises at least one spring part (24) that is rotatable with the first or the second part, is resilient in a direction parallel to the longitudinal axis of the screwable element and cooperates with detents (26) of the respective other part.
