Title: Stud welding method for bolt-shaped components to surface of workpiece
Inventor: FRANZ UDO PROF DR
IPC: B23K9/20
Filed: 1996-05-23
Granted: 1997-07-03
Abstract: The method employs a capacitive energy store (11) which is charged from a source (10) and discharged by closure of a switch (12) connecting it through the bolt (8) to the workpiece (9). The current rises to a peak and then declines slowly while the voltage remains almost constant.  When the current has fallen to the value at which the discharge was struck, another switch (13) is closed to divert current from the weld. The subsequent accelerated contact of the welded surfaces sees no spread of the molten metal, which is utilised entirely for the welding.

Granted: 2001-02-15
Abstract: The invention relates to  a method and a device for detecting the position of a vehicle (F1-F4) in a given area (100), especially a storage facility. The inventive method comprises the following steps: the size and angle of incremental movement vectors relating to the movement of the vehicle (F-1) is detected; a respective reference position of the vehicle (F1-F4) is automatically determined at predetermined locations (O1-O4) inside the given area (100) whenever the vehicle (F1-F4) passes a corresponding location (O1-O4); the current position of the vehicle (F1-F4) inside the given area (100) is detected by means of vectorial summation of the detected incremental movement vectors with respect to the location vector of the temporary reference position. Automatic determination is carried out by a sensor (L1, L2, MS) which is arranged on the vehicle (F1-F4) and interacts in a contactless manner with a respective reference marking (MS) in the corresponding location (O1-O4) exhibiting reflecting and non-reflecting areas (R1, R2; D) which are scanned simultaneously by the vehicle (F1-F4) by means of at least two signals (ST1,ST2). The coordinates (x,y) of the reference position and, optionally, the angle of passage ( alpha ) are determined by evaluating the variation in time of the reflected intensity of said signals (ST1,ST2).
