Patent DE-3808101-A1 (DE)
Title: Method and arrangement for monitoring the machining during milling
Inventor: MUENNING HANS DR ING
IPC: G05B19/4065
Filed: 1988-03-11
Abstract: The invention relates to a method and an arrangement for monitoring the machining during the milling of metal materials. Here, it is often necessary to obtain information about the cutting depth during the milling or about the position of the cutter relative to the workpiece. In order to be able to carry out the monitoring during the machining itself, the invention provides for the cutter and the workpiece isolated from it to be connected in an electric measuring circuit so that a short circuit is made when the cutter engages in the workpiece. These short circuits trigger impulses which in relationship to the number of revolutions of the cutter enable information to be obtained about the cutting depth and the geometric position of cutter and workpiece even during the milling. Therefore predetermined positions of the cutter can be determined and in particular path corrections can be carried out, so that the cutter can be used for automatic processes.

Title: Parking device for motor vehicles
IPC: B60S9/215
Filed: 1988-04-19
Abstract: Hitherto, manoeuvring vehicles into parking spaces has been extremely laborious. The two parking systems known to me supplied by "Sbarro, Switzerland" and "Schulz 4052 Korschenbroich" are expensive and are only installed in powerful vehicles. A new economical parking device with 4 or 2 small transverse wheels (QR) is intended to be capable of being installed in newly developed, popular passenger cars. The QR (1) with sleeve is pivoted over the top at the articulation axis. Approximately underneath it, the guide holder (2) is installed; it permits the extending QR to be guided and secured. Further below on the sleeve, the toothed wheel bar (3) is attached. When the transverse wheel (1) is retracted, the toothed wheel of the electric motor (5) turns the toothed wheel bar upwards, as a result of which the QR is pulled along upwards until it assumes a horizontal position. The electric motor (4) which is installed above the QR thus drives the QR via the chainwheel (6). The parking device is suitable for almost all motor vehicles, apart from extremely small vehicles; it is used to manoeuvre vehicles transversely into parking spaces. <IMAGE>

Title: Process for producing ultrasonic transducers
Inventor: RITTHAMMER GUENTER ING GRAD
IPC: B06B1/06
Filed: 1988-07-11
Abstract: For the centring of a piezoceramic, until now the front face of the transfer layer of ultrasonic transducers has been provided with an annular contour, which however makes it more difficult to coat the surface with adhesive. The object is to make it easier to apply the adhesive and adhesively attach the piezoceramic and a damping ring. For this purpose, a planar surface of the transfer layer is provided centrally with an annular groove and then adhesive is applied to this surface. Thereafter, the damping ring is fitted centrally onto the transfer layer and subsequently a centring ring adapted to the shape of the annular groove is fitted into the annular groove. Finally, the piezoceramic is adhesively attached onto the surface of the transfer layer left free at the centre by the centring ring. In a further process, adhesive is applied to a planar surface of the transfer layer, onto which subsequently the damping ring is fitted centrally. The piezoceramic is then adhesively attached centrally onto the surface of the transfer layer by means of a mould having an annular contour.

Title: Frame for motor vehicles
Inventor: SIHLER BERND DIPL ING
IPC: B62D21/15
Filed: 1988-08-17
Abstract: A frame for motor vehicles, in particular lorries, is proposed having an energy-absorbing front component which has at the front end of each longitudinal member at least two member components which, starting from the front end of the longitudinal member, protrude away from one another towards the front approximately in a V shape and are connected at the front to a front transverse member. At least the front ends which adjoin the transverse member and the front transverse member are arranged at a lower point than the front end of each longitudinal member. The front transverse member forms on the one hand the front termination of the front component and on the other hand a front underride guard. The member component which is located nearest to the centre of the frame is lowered with respect to the member component which extends further outwards. As a result, space is provided for a radiator which extends outwards beyond this member component and can thus be given wider dimensions.
