Abstract: An apparatus for removeing microbes from flowing media, such as water, has an essentially cylindrical container, inside of which there is a reaction chamber with UV radiators arranged on a concentric circle, and it also has inlet and outlet openings for the medium to flow through the reaction chamber in a direction parallel to the cylinder axis and on a path maximizes exposure of the medium to the UV radiation.
Abstract: A pipe connection is formed between a relatively soft pipe segment and a stiffer socket by inserting a split securing ring in a groove of the socket, then spreading this ring and inserting the pipe segment through the split ring into the pipe segment without contact with the split ring. The mounting body maintaining the spread state of the split ring is then removed to allow the spring ring to engage with its intrinsic elastic force along the periphery of the pipe segment. Even if the inner surface of the split ring is provided with a corundum layer or like friction-enhancing structure there will be no damage to the outer periphery of the pipe which might interfere with sealing.

Abstract: The plug-in socket joint secured against sliding movement is intended for socket pipes (1) manufactured by centrifugal casting, in which the spigot end (3) of one pipe may be inserted with radial play into the socket end (2) of the other pipe. In this joint, a sealing ring (8) and a clamping ring (14) structurally separate therefrom are arranged, said clamping ring being composed of a plurality of clamping segments (15) spaced from one another in peripheral direction. The latter have a spherical outer shell surface (17), are connected to each other in peripheral direction by means of a moulded-on intermediate layer of rubber or similar and each have a toothing (19) on their inner surface (18).
Abstract: The spigot-and-socket joint which is secured against sliding is designated to connect the spigot end (3) of a pipe which can be slid into the socket end (2) of another pipe, with radial play existing. In the socket end there are arranged a sealing ring (8) and a separate clamping ring (14) comprising a plurality of circumferentially extending, spaced clamping segments (15) having a spherically convex outer surface (17) and, on an inner surface, a tooth system (19) which, in the presence of axial forces, presses radially onto the spigot end (3) as the spherically convex surface (17) cooperates with a pipe socket's inner surface (18) which tapers conically towards the end. An elastomeric support member (20), which can be fixed in its position at the socket front end and supports the same, is provided on the clamping ring (14).
Abstract: The instant invention is concerned with a cutting machine, and in particular with a meat grinder, having a cutting assembly arranged along a central axis of the meat grinder. The material to be ground is fed towards the cutting assembly which has at least one perforated disk provided with a central boss bore. At least one cutting blade rotates on a drive shaft in front of the first frontal area of the perforated disk. Separation and removal of the accumulated solid particles contained in the material being cut in front of the first frontal area is provided by the cutting blade and by channels or holes located in the area of the central axis.
