A tool for introducing self-tapping dowels in a structure by a drilling process which is accompanied by the generation of large-size drillings, has a shaft connectable with a drive, a dowel holder connectable with the shaft and having a receiving bore which includes a first section adapted to receive a dowel shank and a second section adapted to receive the large-size drillings, and a suction arrangement movable relative to the dowel holder to and from an operative position in which it communicates with the second portion of the dowel holder and draws air therethrough to thereby suck the large-size drillings into the second section of the dowel holder bore wherein they are retained during the drilling process.

An arrangement for producing grooves in walls, ceilings and the like with the use of a hand-held processing machine, has a rotatable material-removing tool driven in rotation by the machine, and a housing surrounding the tool. The housing has a guiding piece through which the tool extends. The guiding piece has a guiding surface which is adapted to lie on the surface of the wall, ceiling and the like, and is inclined at an acute angle relative to the axis of the tool. The guiding piece is detachably mounted on the processing machine.

A dust-intercepting member is so mounted on a hand-held power tool as to contact a structure being acted upon around the tool element of the power tool, by a mounting arrangement which includes two hollow elongated mounting members one of which is received within the other for telescoping relative thereto while being retained against rotation with respect to the other mounting member about the common axis of the mounting members, and a helical compression spring the ends of which are respectively received in the interiors of the mounting members and urge the latter in opposite directions. The other mounting member is attached to an auxiliary hand grip which, in turn, is mounted on a cylindrical extension of the housing by a quick-release clamping arrangement. A setting ring on the inner one of the mounting members determines the depth of penetration of the tool element into the structure. A depth-determining profiled rod is displaceably and arrestably mounted on the auxiliary hand grip. The outer one of the mounting members is connected to the profiled rod when the intercepting arrangement is mounted on the auxiliary hand grip.

Dyes of the formula ##STR1## wherein K is the radical of a coupling component which can additionally contain azo groups, R is hydrogen or methyl, and Z is a fluorine atom, a substituted or unsubstituted amino group, a substituted or unsubstituted hydroxyl group, a substituted or unsubstituted mercapto group, or a substituted or unsubstituted hydrocarbon radical are distinguished by high reactivity and they produce dyeings of good wet- and light-fastness properties. The dyes of the Formula (I) are suitable for dyeing and printing a very wide variety of materials, such as silk, leather, wool, polyamide and polyurethane fibres, and especially cellulosic materials of fibrous structure, such as liner, cellulose, regenerated cellulose, and in particular cotton. They are suitable both for the exhaust method and for dyeing by the pad-dyeing process. They are also suitable for printing, in particular on cotton.

A sensor module for a probe of a tactile coordinate measuring machine has a stationary module base which defines a first measurement plane. The sensor module has a support, which is moveable relative to the module base, for holding a stylus. At least one deformable connecting element movably interconnects the support and the module base. The connecting element has at least a first and a second deformable material layer which, perpendicular to the first measurement plane, are arranged offset with respect to each other. In a preferred embodiment, the sensor module is made from two single-layer module parts arranged above and attached to one another.

The invention is directed to a coordinate measuring apparatus wherein the influences of temperature on the measuring uncertainty of the apparatus are eliminated. Components of the two pivot arms, which determine the spacing A of the rotational axes (6, 8) and the spacing of the rotational axis 8 to the probe axis 10, are made of materials having positive and negative thermal expansion coefficients.
