Abstract: A method for operating a power tool is provided. The power tool has a tool, in particular a drill bit, and a motor, while the motor is a brushless electric motor. In the power tool there is implemented a rotational speed graduation of an electronic form, with which a circumferential speed at the tool of the power tool can be kept essentially constant, while a rotational speed spread DELTA_n of greater than 2 is achieved by the design, dimensioning and/or control of the motor. Also provided is a tool device, for example a core drilling device, with which the proposed method can be carried out. An essential advantage of the invention is that the rotational speed spread DELTA_n of greater than 2 is achieved without a mechanical transmission on the power tool. Instead, a rotational speed graduation of an electronic form is used in the present invention.

Abstract: The invention relates to CPAP-tubulin inhibitors having the general formula (1) or a physiologically acceptable salt thereof; and their use as cancer therapeutics.

Abstract: A pressurized fuel system for an engine includes a fuel pump in a pump protection device structured to drain pressurized fuel from a common rail to provide fuel flow through the fuel pump that limits cavitation. The device includes a valve mechanism having a first valve and a second valve that are movable to an open position and a closed position respectively, in response to valve opening and valve closing rail pressures. The active pressure range of the device may be a medium pressure range.

Abstract: The present invention concerns a rotary compressor for compressing a gaseous medium, comprising an impeller (2), a drive unit (3) and a magnetic coupling (4) comprising a rotating inner rotor (41), a rotating outer rotor (42) and a can (43), wherein the inner rotor (41) is connected to the impeller (2), wherein the impeller (2) comprises a continuous solid portion (25), wherein a first row (21) and a second row (22) of blades (23) are provided at the outer circumference of the solid portion (25) of the impeller, the first and second row of blades being separated by a circumferential middle wall (20), and wherein the blades (23) of the first row (21) are offset in circumferential direction relative to the blades (23) of the second row (22).

Abstract: A hearing device has a housing, in which a loudspeaker and a battery are disposed. The housing has a first housing part and a second housing part. The housing parts are connected to one another by way of a connection. At least one housing part or an attenuation element provided in the connection between the housing parts is formed of an elastic material.

Abstract: A hearing apparatus has a housing, a receiver in the housing, and a sound conductor through which sound from the receiver is conducted out of the housing. In order to render the device as small as possible, the hearing apparatus has a cover piece which is inserted into the housing in such a way that a sound channel is formed. The sound channel is thereby delimited at the sides by the housing and the cover piece. A special sound-conducting tube can therefore be dispensed with.

Abstract: The guide rail has a longitudinal groove arranged along its upper rail side and a cover strip which closes off the groove and bears flush against the plane of the upper rail side. The spacing between opposite groove walls of the groove is smaller than the leveled cover strip. In order to retain the cover strip, each of the groove walls are provided with an undercut and retaining strips provided at both longitudinal sides of the cover strip engage into the undercuts. The cover strip is plastically curved around an axis which is parallel to the guide rail, such that the curved cover strip is smaller than the spacing between the groove walls, and after being inserted into the longitudinal groove, the curved cover strip is leveled by means of plastic deformation, such that the retaining strips are displaced into the undercuts.

Abstract: A battery bay of a hearing device should be better protected against unwanted opening. A housing for a hearing device is therefore provided with: a battery bay that is mounted on the housing and can be moved into an open position as well as a closed position; a projection that is permanently attached to the housing, and a securing element to prevent a movement of the battery bay. The securing element is supported on the battery bay and can be pivoted between a secured position and an unsecured position. The securing element also engages behind the projection in the secured position and the closed position of the battery bay so that the battery bay cannot be moved into the open position. The securing element has a recess in which, in the secured position, a tool can be held to move the securing element into the unsecured position.

Abstract: A hearing device has a housing, in which an earpiece and a battery are disposed. The housing has a first housing part and a second housing part. The housing parts are connected to one another by way of a connection. At least one housing part or an attenuation element provided in the connection between the housing parts is formed of an elastic material.

Abstract: A battery compartment for a hearing apparatus and in particular for a hearing device is to be designed to be more compact. To this end, provision is made for a battery compartment with at least two gripping arms, which has an arm section on its one end and a gripping section on its other free end in each instance and for a sliding element which engages with the arm section of the gripping arms. In a first sliding position of the sliding element, the gripping arms assume an open position in order to insert a battery between the gripping sections and a closed position in a second sliding position in order to fix the battery, in which closed position the gripping sections are moved toward one another.

Abstract: A hearing apparatus is provided with a housing including a first housing mounting element and a control element that is mounted rotatably in the first housing mounting element via a control mounting element. Furthermore the housing has at least one second housing mounting element so that the control element can be optionally mounted rotatably in the first housing mounting element or in the second housing mounting element. Thus the control element can be actuated in a desired position.

Abstract: A hearing device which is simple to assemble and to which a wearing hook can be fastened in a stable fashion is provided.
