In order to eliminate a joining play and a wear play in a straight-line mechanism with a straight guiding member and a carriage sliding on this guiding member, it is provided to equip the guiding surfaces of the guiding member and of the carriage with mutually coordinated profiles. Each of the profiles has at least one wedge which extends in the sliding direction and rises in the circumferential direction and the parts having the profiles can be rotated with respect to one another.

Straight-line mechanism adjustable without play

In order to permit a fast, precisely centric fastening of rotating tools, such as drills or milling tools in clamping sleeves, of such clamping sleeves or of workpiece holding devices, such as clamping chucks 4 in spindles 1 of turning machines, respective holding surfaces 9/10, 23/24 are provided in the respective parts to be connected with one another with profiles 11, 12, 25, 26 which are coordinated with one another in pairs and which each have at least two wedges 13, 15. The wedges rise over imaginary cylindrical reference surfaces 14, 16 radially toward the outside and inside and each drop again steeply onto the reference surfaces and are offset in the circumferential direction by identical angles and have a joining gap in a joining position.

Drill with interchangeable cutting insert

Shaft-hub linkage

A drill having two or more cutting edges is provided with interchangeable cutting members. The cutting members are fastened by screws in corresponding recesses formed in the drill bit. The cutting members are embodied by interchangeable plates and provided with fastening portions behind the main cutting edge, in the direction of cutting. The screws engage through these fastening portions in threaded bores formed in the front face of the drill bit.

Drill having two or more cutting edges comprising exchangeable cutting

A portable heating system for individuals which system includes a heating device for heating a quantity of fluid, an energy source for supplying a fuel to the heating device and an emitting device operatively connected with the heating device for emitting a quantity of heat. The energy source, the heating device and the heat emitting device are constructed as a structural unit with the heat emitting device being insertable into a sheath surrounding an individual so as to provide for the thermal requirements of the individual.
