In addition, a pulse energy monitoring device is provided in the laser adapter 4 which is used for the on-line energy measurement of the emitted laser pulses and whose output signals are applied as parameters for controlling the pulse energy emitted by the laser 9.

Abstract: The fastening device consists of at least one retaining element 13 attached to the seat of the vehicle, this element holding a fastening element 14, which can be moved between a service position and an out-of-service position (parking position). So that the fastening element 14 can be moved easily into the service position and then again into the parking position without the need for any force-transferring element installed at a remote location, the fastening element 14 is connected to the retaining element 13 by means of a latching mechanism 17, which makes it possible for the fastening element 14 to be lowered into a parking position and returned to a service position.

Abstract: A method for unlocking a window pane secured by a fastening element to a frame element of a window frame, with an inflatable pressure tube being located between the window pane and the frame element, said tube, upon being inflated, forcing the window pane out of the frame element. For reliable and improved element unlocking of the window pane, the pressure tube is inflated by actuation of at least one pyrotechnic gas generator connected to the pressure tube.

Abstract: The invention relates to a rotationally symmetrical.sup.1 magnetic bearing cell (1) with a rotor (2) arranged to rotate about the central axis (10) of the cell (1) and having a shaft (4) and at least two axially magnetised permanent magnetic rings (5, 6, 30) fitted an axial distance apart on the shaft and with a stator (3) having pole components (12, 13, 16, 17) and two annular coils (14, 15) associated with the rotor end faces; to improve the radial rigidity without increasing active control complexity, it is proposed that pole components (26, 27, 38) of magnetically conductive material be provided for the peripheral regions of the two axially outer permanent magnet rings (5, 6 or 5, 30) to direct the magnetic flux generated by the annular coils (14, 15) into two substantially independent magnetic flux circuits (28, 29)..sup.1 Translator's: note The German text reads "aufgebautet". This is grammatically not correct. Instead the German text should read "aufgebaute".

The optical element is arranged in thermal contact with a cooling element and is optically dimensioned so as to result in a minimum diameter of the transverse mode profile within the laser resonator.

The safety filter is optically dimensioned in such a way that no change in the focal intercept results when the filter is swung into the viewing beam path. The filter largely absorbs the particular laser wavelength.

Abstract: For defined ablation of a surface, successive partial regions of equal surface area are acted on by a radiation source, preferably a laser, through an optical system. The partial regions are smaller as regards surface area than the whole surface to be processed, so that the respective radiation source can be dimensioned in a less costly manner. Telescope optics with conical surfaces serve as optical systems suitable for this purpose.

A plurality of shanks (12) are attached to cross bar (11) and extend therefrom, mostly forward and slightly downward to points below and ahead of pickup reel (3). The front ends of each shank (11) have a blade (14) extending generally horizontally outward therefrom to cut the plants just prior to the pickup reel (11) lifting them up. A pair of row dividers (15) are provided on the right and left sides of the machine. These dividers are hydraulically rotated to aid in separating the entangled vines without damaging the crop. Each divider (15) rests on a skid plate (19) and is disposed to ride in one of the two outer most furrows to separate the entangled vines of the two drill rows adjacent the furrows.
