Abstract: The present invention relates to a method for in process weld seam testing of a weld seam joining two metallic parts, said method comprising the steps of: providing two laser beams, directing the first laser beam on a first predetermined position on the first metallic part and directing the second laser beam on a second predetermined position on the second metallic part, and detecting the reflected light of the laser beams along the weld seam.

Abstract: A radioactive or activatable seed for use in brachytherapy, and a method for producing the seed, the seed comprising a closed and self-supported casing consisting of (a) a radioactive or activatable metallic material selected from the group consisting of a metal, an alloy and a metal composite or mixtures thereof, optionally in combination with (b) a non-radioactive, non-activatable metallic material; wherein (a) comprises a radioactive nuclide selected from the group consisting of Pd-103, Tm-170, Sr-90, Y-90, Yb-169, P-32, Ge-71, Se-75, Cl-36, Ta-182, Tl-204, Re-188, W-188, Ce-144, Pr-144, Sn-123, Ru-106, Rh-106 and mixtures thereof, and/or an activatable precursor nuclide thereof selected from the group consisting of Pd-102, Rh-103, Tm-169, Y-89, Yb-168, P-31, Ge-70, Se-74, Cl-35, Ta-181, Tl-203, W-186, Sn-122 and mixtures thereof, excluding metallic Pd with natural abundance of Pd-102.

Abstract: The invention describes a storage and dispatch container for variable quantities of radioactive miniature radiation sources as well as a locking and opening device for the said storage and dispatch container and is applicable for the transport of radioactive miniature radiation sources in well organized and undamaged condition. The dispatch containers serve as storage depots at the same time and meet the requirements of radiation safety with passive protection from loss. Their construction permits automatic filling or transfer of the contents using a corresponding device. The container is characterized in that a capillary tube (8) for the uptake of the radiation sources (15) is arranged in the main body (1) of the container and that the main body (1) exhibits a lower end-piece (2) with a fluid-medium connection (4) as well as an upper end-piece (3) with an input/output opening (3a) for the radiation sources (15), which can be locked by means of a locking mechanism (10).

Abstract: In a safety device for vehicle occupants with acceleration-sensitive sensors and with processing circuits for the sensors summing and integrating devices as well as a comparator device for comparing the summation and integration values are provided. The comparator device controls a warning device as soon as the comparison value exceeds a presettable limit value.

Abstract: To recognize change in the storage characteristics of programmable memory elements, particularly EPROMs, the memory content of an addressed memory element or cell is read out, the first time, at normal design voltage level; the data so read are then again read out at a changed voltage level, for example at a higher or lower read-out voltage, or higher or lower operating voltage of the EPROM, and compared. If the data do not match, the particular memory cell will have the tendency to become defective due to loss or accumulation of charge carriers in due course although, for some time yet, the specific memory cell will function satisfactorily. Detection of errors upon operation under changed voltage conditions provides early warning of failure of a cell.
