Patent DE-19746970-A1 (DE)
Title: Obstacle recognition for rail vehicle with automatic guidance
Inventor: UEBEL HELMUT
IPC: B61L23/04
Filed: 1997-10-24
Abstract: The method involves using an on-board computer (BR) for storing path data in form of coordinates of points (SP1-SP4) lying in certain distances in the center between the rails (Sch1,Sch2). The points are targeted through a vehicle sensor (S) by pivoting the sensor signal around an angle (a) with respect to the momentary path direction (FR), depending on a track curve and a distance (d).  The aperture angle (w) of the signals received by the sensor, in whose center the targeted point lies, is changed in such way in dependence on the distance and the sensor angle, that an track space (SR) of interest is exclusively recorded. Independent claims are also included for a corresponding obstacle recognition device.

Title: Method for changing optical property at surface and/or inside workpiece using laser
Inventor: LENK ANDREAS DR
IPC: B23K26/06
Filed: 1997-12-01
Abstract: The method involves conducting an energy input by a focused laser beam at and/or in a transparent workpiece for a laser. Two or more laser pulses in quick succession are implemented. A mode-synchronized and Q-switched rigid body laser is used. A spacing is adjusted between at least two pulses and the pulses follow one another at least at a spacing where the changes of the optical property of the previous pulse are effective with the following pulse. A programmable 2D or 3D relative movement is implemented between the laser beam and the workpiece, synchronized between the course of movement and the laser pulses.

Title: Warm air central heating system
Inventor: DOEPP MARGOT
IPC: F24D5/00
Filed: 1997-12-18
Abstract: The warm air central heating system has fresh air or a mixture of fresh air and recirculated air fed to a central heating device before ducting the heated air to each room. The air extracted from each room is passed through a cross-flow heat exchanger (1) for heat exchange with the fresh air for ventilation of the room, with a pre-heater (4) for the fresh air controlled in dependence on the external temperature. The heating device could be e.g. a gas or oil-fired boiler, an electric heating device or a heat pump, or to decentralized heating devices.
Patent DE-19756932-A1 (DE)
Title: Device for cutting of plastic profiles avoiding deformation
IPC: B26D1/00
Filed: 1997-12-20
Abstract: Plastic profiles like those used in window production are either squeezed or compressed lengthwise by the common techniques of cutting. By using a blade with at least one specifically shaped opening there will be no vacuum created in parts of the profiles during the cutting process. The blades have to be pre-tensioned in a guide with guide rods which can be pre-tensioned either at the top or at the bottom individually. A special structure of the surface of the blades facilitates the precise and deformation free cutting of the profiles.

Filed: 1997-12-17
Abstract: The milling works include a cylinder calibration for a cylinder set consisting respectively of three cylinders with a noncircular caliber form. The last calibers of the milling works are locally enlarged at their extent, at which the expected diameter of the ingoing reed is lower than a nominal size, and are locally reduced at their extent, at which the expected diameter of the ingoing reed is larger than a nominal size. The milling works include a cylinder calibration for a cylinder set consisting respectively of three cylinders, having a noncircular caliber form, considering the form change in the cross-section of the reed and working against a noncircular reed outside diameter. The last calibers of the milling works are locally enlarged at their extent, at which the expected diameter of the ingoing reed is lower than a nominal size, and are locally reduced at their extent, at which the expected diameter of the ingoing reed is larger than a nominal size. A manual or automatic measurement of the reed diameter is preferably performed, whose data are stored in a data base for statistic analysis, and are supplied to a CNC machine for a reduction or increase of the theoretic final caliber.

Patent DE-19821363-A1 (DE)
Title: Method of actuation regulation of switching elements of automatic vehicle transmission
Inventor: BOTHE EDGAR
IPC: F16H59/46
Filed: 1998-05-13
Abstract: The method involves taking into account potential slip. A regulator generates a control signal (1-3) for the switching or control element onto which is superimposed a modulation signal (4). A measurement parameter correlated with the slip (5) is detected. The regulator cyclically derives a correlation limit from the measurement parameter and modulation signal and controls the drive signal against a deviation if upper or lower correlation values are exceeded, thus operating the transmission in a low slip region. At least two control elements are operated in the low slip region, where at least one is driven by the modulation signal so that the sum of the slip of the control elements is approximately constant.
