Title: Method and apparatus for the on-line monitoring and control of the weld-in depth during laser beam welding
Inventor: SOKOLOWSKI WALDEMAR DR
IPC: B23K26/03
Filed: 1993-04-23
Abstract: In the method according to the invention, the weld-in depth is obtained from the ratio of the spectral intensities of two ion lines of different ionisation stages of a chemical element which is located at the focus of the laser radiation. The invention is based on the experimental findings that the weld-in depth is a function of the temperature (distribution) of the laser-induced welding plasma. The concentration ratio of the ions of different ionisation stages is a suitable and sensitive measure for this temperature distribution. Simple determination of this concentration ratio is possible via the detection of the intensity ratio of two selected spectral lines which are emitted by the ions of different ionisation stages. The intensity ratio of an ion line and an atomic line is preferably measured. The weld-in depth is controlled via the variation of process parameters such as the laser power and the feed rate. Calibration curves, among other things, can also be used to monitor and control the weld-in depth. The invention permits on-line monitoring and control of the weld-in depth, during which spontaneous, process-induced fluctuations which are caused, for example, by workpiece inhomogeneity or surface contamination ...

Patent DE-4317021-A1 (DE)
Title: Packaging unit
Inventor: KECK JUERGEN K
IPC: B65D71/00
Filed: 1993-05-21
Abstract: A packaging unit consists of a bottom part for receiving the packaged product and a lid or bearing part, which parts can be connected non-positively to one another in such a way that the bottom part and the packaged product located therein can be carried with the aid of the lid part without using plastic films or additional attachment means. In this case, the entire packaging unit can be designed as a single-material package, for example made of corrugated cardboard or solid cardboard and thus does not pose any problems concerning disposal. This solution can be implemented in a particularly advantageous manner if the required locking positions between the lid part and the bottom part are produced by locking edges which, in turn, can be implemented simply by corner tabs or edge tabs on the cardboard blanks.

Patent DE-4323671-A1 (DE)
Title: Continuously variable camshaft adjustment
Inventor: BERNDORFER AXEL DIPL ING
IPC: F16D3/10
Filed: 1993-07-15
Abstract: The invention relates to an adjusting device for two shafts arranged coaxially with respect to one another. To achieve a different phase relation between two shaft sections, it is known to connect a hydraulically actuable adjusting piston to one shaft section, the latter acting via a ball on an adjusting ramp which is connected to the adjoining shaft section. A radial adjustment of the piston by means of a pressure medium brings about a relative rotation of the two shaft sections. This embodiment requires a special means of feeding in the pressure medium and a relatively large installation space. Furthermore, the components which bring about the adjustment do not all remain continuously in play-free contact. The object of the invention is to obtain a device with a large adjustment range which is easy to assemble and ensures play-free and low-noise operation. According to the invention, a two-stage wedge-type transmission is provided between a camshaft 2 and a roller carrier 3 in order to provide angular adjustment. <IMAGE>

Title: Spacer for fixing a printed circuit board in a housing, and an electrical appliance having a printed circuit board and a spacer
Inventor: WARKUS MANFRED
IPC: H05K7/14
Filed: 1993-08-06
Abstract: The invention relates to a spacer for fixing a printed circuit board, which is arranged between two walls of a housing, and to an electrical appliance having a printed circuit board and such a spacer. In order to be able to fix a printed circuit board securely in a housing of an electrical appliance without any additional holes and thus without additional sealing points in the housing, a spacer has a shoulder as far as which it can be pressed in a secure position into an aperture in the printed circuit board, said spacer projecting beyond the printed circuit board on both sides and having a head which rests against one wall and a foot which rests against the other wall of the housing. Using such a spacer, the printed circuit board can be provided with a spacer at any desired point, in particular even at points where access from outside the housing is difficult in order, for example, to be able to absorb mass forces, which are particularly severe, just at such a point.
