An interface device, coloring agent and method for imparting color to food material during the decorating of foods. This interface device, coloring agent and method for imparting color to food material during the decorating of foods can be used to impart color from solid, liquid or semi-liquid coloring compounds to a wide variety of food material such as frosting and icing.

An optical fiber cable production method includes: feeding a core including optical fibers; winding a reinforcing wrap around the core and forming an overlapping portion in which end portions of the reinforcing wrap overlap each other at a portion of the reinforcing wrap in a circumferential direction; and performing extrusion molding of a sheath on an outside of the reinforcing wrap. The overlapping portion extends in a longitudinal direction of the optical fibers. In the performing extrusion molding, a resin that forms the sheath is inserted into a portion of the overlapping portion.

The invention relates to a device for producing plastic pipe from a molten plastic tube. The device comprises a injection head for connection to an extruder for the extrusion of the molten plastic tube and several molding jaws in each case having a molding surface for the molding of the extruded molten plastic tube, which, for molding the extruded molten plastic tube, are arranged, in each case in pairs, guided by means of a drive device along a molding path in the production direction of the extruded molten plastic tube. The molding surface in each case partially encircles a receiving space for receiving the molten plastic tube. According to the invention, at least one of the molding jaws has a sensor device which comprises at least one sensor with a data-capturing sensor head, which is arranged such that its capture area comprises an area of the molding surface and/or an area of the receiving space.

This invention relates in general to a multilayer tube and methods of making the same. In particular, this invention relates to a multilayer tube used as a riser, such as those that may be connected to shutoff or “stop” valve on one end and a plumbing hook-up to the other end. The multilayer tube comprises a first inner polymer layer and a second outer polymer layer, wherein the first and second polymer layers are not substantially bonded to each other. To facilitate use, the tube may additionally comprise one or more overmolded components, such as pipe connectors, plumbing connections, plumbing fittings, valve connectors and appliance connectors. The layers are not substantially bonded.
