Abstract: The dental device comprises an abrasive disk having a hub made of synthetic material and a spindle with a collet, the opening of the hub having an inner bead and the collet a rotation lock and an axial lock for receiving said bead in the hub opening, the greatest diameter of the spindle with its rotation lock being greater than the diameter of the hub opening with its bead. This construction allows, on one hand, an easier mounting of the abrasive disk on the spindle, and, on the other hand, a high torque transmission.

Abstract: A center tunnel for a vehicle, especially a motor vehicle, has a section shape that is open at the bottom and has sections in the form of hollow members that are directed lengthwise, at least areawise. A center tunnel that has a simple design and can be manufactured economically, and which is torsionally rigid and can accept high forces, is formed by a double-walled hollow body manufactured by the internal high-pressure shaping method, viewed in cross section, with spaced wall sections of the hollow body being brought together areawise.
Abstract: In the case of the pipe connection of two overlapping pipes a flexible ring is arranged between the interior pipe and the exterior pipe and, before the bracing, is axially displaceable on the interior pipe. The flexible ring and the exterior pipe have a spherical interacting outer and inner contour which ensures the angular mobility. The fixing of the pipe connection after the adjustment takes place by two tensioning bows which are fixedly mounted on the exterior pipe. This permits a particularly easy handling during the adjustment and the fixing of the pipe connection.

Abstract: A rear mounting having two scoop elements is detachably fastened in the rear cutout of a convertible vehicle by way of fastening elements. The scoop elements are constructed to be separable in a longitudinal center plane so that, in an in-use position on the vehicle, the two scoop elements form a connected unit and, in a transport position, these scoop elements can be stowed in the vehicle in a mutually detachable and separate manner.
Abstract: A removable hardtop for an automobile has a rear window and can be secured to the adjoining body via releasable latches. To stiffen the hardtop in the transverse direction, the hardtop is provided with a parcel shelf below the rear window. The shelf joins at least the two lengthwise side parts of the hardtop with one another.

Abstract: A head for a scanning probe microscope comprising a tuning fork (130) with an SPM tip (134) attached to one prong of the tuning fork. An AC signal (Vin) generated by oscillation of the tuning fork is supplied by a pair of electrodes on the tuning fork to input terminals (110 and 112) of a source-follower circuit comprising a dual-gate GaAs-MESFET (114), the gates (G1, G2) of which are connected in parallel to one of the pick-up electrodes via one of the input terminals (110), the other of the pick-up electrodes being earthed via the other of the input terminals (112). The signal (Vin) is processed by the circuit and supplied to two output terminals (126 and 128) as an output signal (Vout). The megaohm output impedance of the tuning fork is thus translated into an output impedance of the order of a hundred ohms, thus improving signal transfer efficiency from the head to an external signal amplifier.

Abstract: A cover and housing having a mounting arrangement, especially for a selector lever housing. According to the invention, the cover is fastened by means of two bearing points to provide a method of fastening a cover that can be mounted simply without adjustment and provides an exact fit for the cover. The first bearing point is made cylindrical and the axis of this cylinder runs parallel to a mounting direction or placement direction of the cover. The second bearing point is made wedge-shaped and the wedge axis lies in a plane that is perpendicular to the mounting direction or placement direction and is aligned so that it is not parallel to a tangent at the first cylindrical bearing point.

Abstract: A covering part made of a flexible material for an end area of a vehicle, particularly a passenger car, in sections, forms the outer skin of the vehicle body and, by way of laterally exterior, longitudinally directed sections, extends to adjoining wheel housings of the vehicle body. A simple fastening, which includes few components, for the laterally exterior, longitudinally directed sections of the covering part as well as an improved mounting and a relative insensitivity to tolerances are achieved. On each longitudinal side of the vehicle adjacent to the wheel housing, a holder is provided which is made of plastic. The holder is fastened on the vehicle body side. At the same time, the holder is used for fastening the upper edge area and the lower edge area of the longitudinally directed covering parts. In addition, the holder forms a partial wheel housing shell.
Abstract: The invention relates to a method and a device for monitoring the position of a variable valve control. In order to monitor the position of a variable valve control in which the construction expense is reduced, it is proposed to perform a cylinder-specific analysis of the nonuniformity of the rotational speed of the crankshaft and from this to determine the operating state of the valve control, possibly for each cylinder individually.
Abstract: A method for the operation and for the evaluation of signals of an eddy cent probe wherein a transmitting coil is supplied with alternating current with preferably three frequency components. The receiving coil signal corresponding to an a.c. voltage is broken down into corresponding frequency components and by phase-control rectification projection signals are formed corresponding to a real part or an imaginary part of the coil signal. From at least two, optionally individually amplified projection signals of the same type (real or imaginary signal) differential signals are formed. Finally, by the combination of at least two differential signals a combination signal is formed and evaluated. In particular, quotients and amount or value sums of differential signals are formed. The method offers decisive advantages in seeking mines in connection with the suppression of disturbing ground or soil signals and in the identification and classification of mines on the basis of signals from an eddy current probe.

The stiff bristles are recessed with respect to the soft bristles. The elongated body portion is hollow and further includes a motor in the hollow portion, which is operatively connected to the circular portion for rotating or oscillating the circular portion. A switch is operatively connected to the motor to provide momentary and continuous operation of the toothbrush. A worm gear and a pair of step gears are located in the hollow portion. The motor is operatively connected to the worm gear and the step gears are operatively connected to the worm gear and to each other.

Abstract: There is described an apparatus for bundling a drafted roving (4), comprising a rotating conveying surface (3) provided with air through-holes (6) succeeding each other in direction of rotation (9), and comprising a suction means connected to the conveying surface (3) on the side facing away from the roving (4) in the vicinity of the air through-holes (6), which suction means forms a slot-like suction zone (5) for the roving (4) extending in direction of rotation (9) of the conveying surface (3). To create advantageous constructional conditions, it is proposed that the suction zone (5) should have at least one suction slot tapering in direction of rotation (9) of the conveying surface (3) from at least two rows of holes to one row of holes.
