Abstract: A locking device for pipes, comprising an inner and an outer pipe provided with adjoining and corresponding circumferential grooves for releasable locking engagement via a locking ring fitted in the grooves and thus releasable locking between the inner and the outer pipe by alteration of the radius of the locking ring, wherein the locking ring has an open section or circle sector along the periphery thereof and is provided, at least at the two radial ends thereof, interrupted by the open section, with two respective guide members comprising respective guide surfaces that are slanted relative to the periphery, and wherein a first one of the guide members is provided with an end stop and a second one of the guide members is provided with a control mechanism protruding through an oblong opening provided through the outer pipe along a portion of its radial groove, wherein the radial displacement of the control mechanism along the oblong opening increases the open section or circle sector of the locking ring while

Abstract: A gate valve comprising a valve body (2) provided with an inlet opening (3), an outlet opening (4) and a fluid flow channel (5) connecting the inlet (3) and the outlet (4) openings. The valve body (2) further comprises a control body (6) extending laterally to the fluid flow channel (5) and having an outer opening (7). Also, the gate valve (1) comprises a gate member (8) movable within the control body (6) back and forth through the outer opening (7), between an open position and a closed position, for controlling fluid flow through the flow channel (5). The gate valve (1) further comprises a housing (12) comprising an inlet member (13), an outlet member (14), a top member (15), and a bottom member (16).

Abstract: The invention relates to a gate valve with a housing, having an inlet and an outlet, between which a flow area is arranged, with a sealing insert in the flow area and a sliding element cooperating with a contact area of the sealing insert in the closed state. In a gate valve of this kind, the function must be improved. For this purpose, the sealing insert has a rigid body, which is permanently connected with at least one additional area with a lower rigidity.

Abstract: The invention can be described as a Method Handler (MH), which consists of several parts used to check and create different methods for microfluidic instruments. The part that creates methods can be called the Method Editor (ME). It is used to create a scheme of operations that together with the instrument builds up an application for a specific disc type. MH also checks if a method is executable on a specific instrument. This is done in a part called Batch Run (BR).
