  • Patent number: 7176696
    Abstract: In a method of detecting and eliminating foreign bodies in tobacco, a flow of tobacco advances first through a preparation zone where it is gathered into a continuous ribbon of tobacco filler, then through a forming station at which the filler is used to fashion a continuous cigarette rod, and finally through a cutter device that divides the rod into cigarette sticks; the advancing flow is directed at a given point through a detection device and exposed to electromagnetic radiation of microwave frequency emitted and received in such a way as to generate output signals reflecting any variations in moisture content along the flow of tobacco, caused by the inclusion of foreign bodies and associated with given portions of the flow each coinciding with a singly identifiable cigarette stick.

  • Patent number: 7043333
    Abstract: In a machine tool with a spindle capable of motion along at least three axes x, y, and z, the position of the spindle is checked by a device that operates utilizing electromagnetic signals sent out by four emitters, located externally of the machine tool, and picked up by a receiver mounted directly to the spindle. The signals are fed into a master control unit and processed by circuits in such a way as to produce an output that can be used to verify and if necessary correct the position of the spindle on the three axes X, Y, and Z.

  • Patent number: 7022095
    Abstract: The invention relates to a sports brace comprising an elastic woven or knitted fabric, which for a sport of the kind that is performed using the arm or hand can be secured to the applicable arm or wrist (2) of the person using it by means of a closure (4). In order to provide that the sports brace (3) has better relief of the player's hitting hand or arm, compared to known braces, the invention proposes providing a plurality of weights (15), distributed over the surface, which act counter to the force of the ball hitting the racket used. To that end, the weights (15) or partial masses (18) of the weights (15) are movable within limits, so that their distribution over the brace also assures effectiveness at various impact angles of the ball or given a different posture of the hitting hand (1).

  • Patent number: 7002172
    Abstract: An electronic safety system for the detection of a shaft failure and for the interruption of the energy supply to the shaft includes at least one measuring light guide (13) which is firmly routed in the shaft longitudinal direction, co-rotates with the shaft (1) and is connected to a light source (18) on a light inlet side (14). In the event of a shaft failure, the measuring light guide will break to diminish light transmission therethrough, with the absence of light on a light outlet side (15) being detected by an optical sensor (19) and being used, via evaluation and control electronics (20, 21), as a signal for the shut-off of the further energy supply at a fuel shut-off valve (22). The measuring light guide is fixed to a measuring sleeve (4) attached at both ends to the shaft.
