Abstract: Beim Schweißen und Bohren mit Laserstrahlen ist die Wärmeabfuhr im Werkstück in radialer Richtung im Randbereich des Strahls wesentlich besser als in der Mitte, so daß selbst bei einer homogenen Engergieverteilung über den ganzen Strahlquerschnitt die Werkstücktemperatur im Mittelbereich des Strahlquerschnitts unter Umständen wesentlich höher ist als im Randbereich. Da praktisch alle Laser- und Korpuskolarstrahlen eine Gauß'sche Intensitätsverteilung haben, liegen die Verhältnisse in der Praxis noch wesentlich ungünstiger. Daher wird gemäß der Erfindung ein Laserstrahl (2) auf die Grundfläche eines aus durchsichtigem, brechenden Material bestehenden, auch als Axikon bekannten Konus (5) gerichtet. Beim Austritt wird der Strahl so gebeugt, daß eine divergierende Intensitätsverteilung in Form eines Hohlkonus entsteht. Durch eine nachgeschaltete Linse (6), die in Bezug auf das Axikon oder auf ein Werkstück (7) axial verschiebbar ist, können auf letzterem ring- oder topfförmige Temperaturverteilungen erzeugt werden, die eine Homogenisierung der Temperatur im Werkstück bewirken.

Abstract: The garage is only slightly larger than a motor car. The problem to be solved is that is should be possible to drive in and out in the same way as when parking a car at the kerb, no more space being necessary in addition to the garage than when parking on the street. The solution to the object is a small garage which has a wall (1) as a supporting structure for its roof (2) on only one longitudinal side, having a single door (3) on the other three sides, which closes three sides and can be raised. At both ends of the garage there is an upper swivel arm (4) and a lower swivel arm (5), the lower swivel arms having a bend which keeps the door opening free when the door is open. At the inner side of the supporting structure, there is a kerb (6). The principal application is in situations where there is insufficient space available for the erection of a conventional garage. <IMAGE>

Abstract: The invention relates to a device for determining the real or the virtual distance of a source of light (3) from a measuring plane (20). Such devices are preferably em- pioyed in position detectors in which light impinges on the surface of the object to be measured, said light being reflected from said surface towards a photodetector. The light emitted by the light source is imaged at different points on said detector, this depending on the position of the surface of the object to be measured. According to the invention, the imaging system (71,72,73) and the position-sensitive detector form a rotationally symmetrical arrangement. This renders the function of the device independent of any lateral displacement of the light source, of different degrees of reflexion of scattering produced by the surface of the object to be investigated, and of the shape of the surface of the object to be investigated.
