The packing of a tubular casing segment which has been shirred together into a hollow cylindrical shirring formation occurs in a tubular net of such configuration that first, with the shirring accomplished with the aid of an abutment which is movable on the shirring tube, a certain initial segment of the tubular casing length is allowed to be left unshirred. Following termination of the shirring, ...

An annular article-wrapping member is disclosed in which a shrinkable wrapping material is wound on the outer periphery of an annular article to be wrapped in such a manner that the direction of shrinkage of said shrinkable wrapping material coincides with a circumferential direction of the outer periphery of the annular article. The overlapped portions of the wrapping material together. The shrin...

A device for mounting a tap unit on the side of a bathtub comprises a stable retaining frame, whose principal elements are two parallel mounting plates located at a vertical distance from one another. These two mounting plates laterally retain the various sanitary elements at two spaced-apart locations, with the result that these can be fitted in an extremely torsionally rigid manner in an install...

A cable arcing detection circuit arrangement comprises a discriminator 7 to discriminate between relatively short current transients in the cable 1 and prolonged current transients due to arcing. In the event of cable arcing, preferably solid-state switching means 5 responds to an output from the discriminator 7 to bring about disconnection of the power supply 2 from the cable. The switching means...

A contact nozzle for a wire-shaped welding electrode for arc welding is designed as a contact tube in the front section and as a guide channel for the electrode in the rear section. The guide channel is formed by an open groove made in the nozzle body. The feed by the electrode is hindered in the rectilinear feed direction by a convex projection of the groove wall. Particles, dragged into the nozz...

A positively obtained fold arrangement in a folding-top covering of a folding top is controlled by a round-bending fold which extends in the direction of width of the folding-top covering and is stiffened in terms of bending transversely relative to its path. When the folding top is opened, the folding top covering is drawn into its fold form automatically under the tensile force of a tension-spri...

Partial stiffening of a folding-top covering of a folding top of a convertible vehicle is provided by a wide-shaped elastically stretchable tension-belt element 9 which is stretched between two supporting structure members 2, 3 of the folding top and which extends underneath the stretched covering and bears supportively thereagainst. So that the tension- belt element 9 can be used for stiffening a...

The process is accomplished in three stages, viz. two cooling stages and one re-heating stage. Intensive mixing and scraping of the product from the container walls is used.
