Abstract: A meat grinder having a screw conveyor, a blade journal mounted on the screw conveyor in a rotationally fixed manner, and a cutting set. The cutting set includes a perforated disc which is supported in a stationary manner on the meat grinder housing and a blade which is mounted in a rotationally fixed manner on a supporting portion of a blade journal. The blade journal is inserted in a bearing bore of the screw conveyor. An insertion end of the blade journal protrudes from the supporting portion in a radial direction, and a stop surface is located between the insertion end and a circumferential side of the supporting portion. A fastening ring is pushed over the supporting portion of the blade journal to the stop surface and can be connected to the screw conveyor, thereby achieving a detachable connection of the blade journal with the screw conveyor.

Abstract: The invention relates to a blade, more particularly for a meat grinder. The blade (10) has a collar-type sealing ring (18) between the hub (11) and the inner ends of the blade wings (14). The sealing ring (18) has the same height as the hub (11) as the adjacent sealing ring (18) has or the hub (11) has a smaller height. The hub (11) thus does not impede the rubbing of the cutting edges (16, 17) of the blade (10) or the rubbing of the sealing ring (18).

Abstract: The invention relates to a reliable cutting set system for a meat mincing machine. The mutually matched coding (14, 24) between knife pins (10) and the cutting set element (20) prevents an incorrect installation of the cutting set element (20) after a cleaning process or during the initial assembly, thereby increasing the operational safety. The invention allows a detection of the correct cutting set element (20) of a cutting set system and thus an unambiguous allocation of the cutting set element to a knife pin (10) of a cutting set system.

Abstract: The invention relates to a cross-shaped support (10) for a meat-mincing machine. The cross-shaped support (10) has a hub (11) with a central bore (15), an outer ring (13), and multiple webs (12) which extend between the hub (11) and the outer ring (13). A groove (14) is provided on the exterior of the outer ring (13) in order to support the cross-shaped support (10) in the meat-mincing machine in a rotationally fixed manner. The cross-shaped support (10) additionally functions as a tool, for example the cross-shaped support has projections (16) which allow a simplification of the assembly or disassembly of the knife pin from the meat-mincing machine (FIG. 1).

Abstract: A process for polymerizing or copolymerizing ethylenically unsaturated monomers in the presence of free-radical polymerization initiators, wherein the polymerization is carried out at temperatures from 100° C. to 350° C. and pressures in the range of from 110 MPa to 500 MPa in a continuously operated polymerization reactor which is controlled by a pressure control valve at the outlet of the polymerization reactor, the process comprising continuously monitoring the pressure within the polymerization reactor, feeding a pressure signal to a controller for controlling the control valve and having the controller altering the opening of the pressure control valve to control the pressure within the polymerization reactor, wherein the controller starts an emergency shutdown program when the pressure control valve closes more than a preset threshold value and the pressure within the polymerization reactor decreases below a preset pressure threshold.
