In securing an anchor in a borehole in a receiving material, a settable hydraulic dowel compound is introduced into the borehole either before, during or after the placement of the anchor member. The dowel compound includes an expandable component. The diameters of the borehole and the anchor member are selected so that an annular gap extends around the anchor member with the gap having a maximum ...

Asbestos-free fiber reinforced hydraulically setting materials, which comprise a slurry of one or more hydraulic binding agents, fibers, water and perhaps additional additives, are obtained when, as fiber, 2 to 20% by volume of filter fibers and 0,5 to 20, preferably 1 to 10% by volume reinforcing fibers are used, both of which are subjected to preliminary treatment which improves their dispersabi...

Clear film is laminated to a base such as paper, paper-like materials, plastics and board through the medium of an adhesive which is curable by ultra-violet or electron-beam radiation. The adhesive is irradiated through the clear film to cure it in the absence of oxygen excluded by the act of bringing the film and base together. High solids adhesives with low viscosity and a high flash point are p...

An apparatus for manufacturing molecularly oriented plastics pipes includes a tubular mould of transverse dimensions equal to those of the pipe to be produced and equipped with a device for admitting a fluid under pressure into a region intended to receive the pipe section to be expanded, a member for closing and grasping one end of the pipe section of a tubular sleeve which opens into the mould b...

A socket 1 is fixed to one end of a filament 2 and a head 3 is fixed to the other end of the filament, the socket including a through hole 4 and an annular flange 5. The head which is insertable into the through hole includes a projection 7 formed in the circumferential direction relative to the axis and a recess 8 formed along the axis of the head. The recess enables the diameter of the head to b...

Apparatus and methods for constructing complex patterns and representations are described having particular application in the construction of a printing plate for printing security documents and/or banknotes. A large computer memory is employed to store in digital form signals which will reproduce in a high definition scanning display pictorial and linear patterns and the like. The display is typ...

This ski boot comprises a boot shell having a front gaiter and a rear gaiter associated therewith, as well as a lever element which is pivoted at one end to either of said gaiters, preferably the rear gaiter, for rotation about the pivot axis. Journalled to a middle portion of the lever element is an adjustment assembly for adjusting the working length of a pair of cables which are attached with t...

A coupling for use in securing a hook-shaped sound part on a behind-the-ear hearing aid consists of a two part connector with a free position in which the parts can be assembled and separated, and a coupled position in which the hook-shaped part can be turned in relation to the hearing aid. A coupling link with a plug-shaped part is inserted in the hearing aid so that the plug-shaped part extends ...
