Abstract: A system and method for providing process chemicals. The system includes a housing comprising a functional component positioned in a first compartment, a control module positioned in a second compartment and at least one connecting line positioned in a third compartment. At least one compartment is positioned in a defined location in the housing. Modules may be removable received in their respective compartments.

Abstract: A plastic transporting container for liquids, in particular high-purity liquids, has a submersion tube (1) which extends from a top wall (2) of the container to the container base (3) and is integrally formed in the transporting container. At its end which opens out in the top wall (2) of the container, the submersion tube is provided with a screw-connection device (6).

Abstract: The invention relates to a closure stopper for containers of liquids, which is configured as a one-piece plastic part. A central degasifying vent (6) is covered on the inside by a bonded-fibre filter (7). An expansion-resistant wall (5) projects from the inner side (1a) of a ceiling wall (1) that surrounds the degasifying vent (6) on all sides at a distance. The bonded-fibre filter (7) is fixed to a protrusion (8) that is melted onto base of the expansion-resistant wall (5).

Abstract: In a hose coupling with a coupling sleeve and a coupling nipple and a valve insert (9) provided therein, the valve spring, the holding element and the valve seat of the valve insert are designed as a one-piece component, and the valve spring (11) has a cavity (21) which is closeable.

Abstract: Container for transporting, storing and dispensing chemical products, including an inner shell made of fluoroplastic, particularly PFA, fitted at its upper part with a stopper device traversed by filling and dispensing connections, and an outer shell exhibiting a substantially cylindrical outer shape and an inner shape substantially matching that of the inner shell.The outer shell (1) is made up of a cylindrical part (6) which, at its lower part, is integral with a base (7) of quadrilateral cross-section and of greater cross-sectional area than that of the cylindrical part of the outer shell.

Abstract: A punch press which has an X-Y guidance system for moving the workpiece relative to the workstation also includes means for rotating the workpiece on the worktable upon release of the workpiece from the X-Y guidance system. In this fashion, the workpiece may be rotated into a reoriented position and then reclamped in that position within the X-Y guidance system. This press includes a tool mounting means on the head of the press and means for effecting reciprocal motion of the tool mounting means along a vertical axis and rotation of the tool mounting means about that axis. Generally, the press will also include a die assembly in the base which includes at least a portion which is rotatable about the same vertical axis so that the workpiece when gripped therebetween may be freely rotated in a fixed clamped position to effect the desired reorientation.
