Abstract: Apparatus and methods for hydrolyzing protein-containing raw material into water soluble protein and other products. The apparatuses and methods comprise an optional collection or processing stage in which protein-containing raw material, such as fish or animal carcasses from food production plants, are collected and optionally processed. The raw material is then reacted with one or more enzymes to hydrolyze the protein present, after which the one or more enzymes are inactivated and the components separated. The processes and apparatuses, which can be run as a batch processes or, advantageously as a continuous processes, can yield water soluble protein, oils, bone meal and other products that have utility as food or food additives.

Abstract: The present invention provides for a pipe fitting for a panel, especially for a panel of a lid for a container, as on a container wall. A pipe section protruding from the panel is provided wherein the front of the pipe fitting is fastened to the panel in the assembled state. A flange having a groove for a seal and a pipe socket extend from the pipe section for passing through an opening in the panel. The pipe socket forms a positive fit connection to the panel through deformation to the assembled state and the seal provides a non-positive fit against a surface of the panel.

Abstract: A socketless fitting for releasable connection of a pressurized line. The fitting has a housing body with a receiving opening to insert one end of the line, and an inner sleeve attached in the housing body in an arrangement that extends coaxially within the receiving opening for engagement into the inserted line end. The inner sleeve is fastened in the housing body media-tight around the periphery by a connector and preferably engages in the line media-tight around the periphery. A clamping element axially movable in the receiving opening cooperates with an inner surface of the housing body to secure the line end onto the inner sleeve. Media-tight outward sealing is accomplished by sealing engagement of the essentially rigidly secured inner sleeve in the line, because the inner sleeve itself is also tightly joined to the housing body.

Abstract: Plug-type connector for compression systems, having a housing part and a plug part. The plug part has a plug shaft that can be hermetically inserted into a receptacle opening of the housing part and releasably arrested by a retainer element. Retainer projections, elastically movable in the radial direction, seat the retainer element in an arrested position between an inner annular shoulder in the receptacle opening and an outer annular shoulder of the plug shaft. The retainer element on the plug shaft is axially displaceable between a safety position in which the retainer projections are blocked, and a release position in which the retainer projections are freed for radial release movement.

The holding element (20) has arresting elements (28, 30) each of which engage behind a locking edge (24) of the connector component (4) when a lock-in connection (28, 24; 30, 24) is formed.

Abstract: The present invention relates to a pressure medium plug-in connector, consisting of two connector parts, i.e. a housing part (2) and a plug part (4), wherein the plug part (4) with a plug shaft (6), via at least one peripheral seal (10) located in an annular groove (14) of the one connector part (4) and interacting with a peripheral sealing surface (18) of the other connector part (2), can be inserted in a sealed manner into a receiving opening (8) of the housing part (2) and can be secured against release by means of a locking arrangement (12). The locking arrangement (12) is constructed in such a way that a partially plugged, prelocked position and a completely plugged, fully locked position are ensured. In the prelocked position, a seal is present which is so incomplete that, if pressure is applied with a pressure medium, a clearly limited perceptible leak, particularly in the form of an audible leaking sound, occurs.
