The present invention relates to face masks to control and improve the quality of inhaled air. Claimed and described is a respiratory face mask comprising a flange and a filter layer, the flange having an inner periphery and an outer periphery and a first and a second width measured perpendicular to the inner periphery between the inner periphery and the outer periphery, characterised in that the first width is greater than the second width. Preferably, such face masks are strapless and rely on a hydrogel adhesive for attachment and sealing. Further claimed and described is an improved cover layer for an adhesive of such a face mask.

Device for producing pressed articles

A method and device for inserting radioactive radiation sources into applicators and for withdrawing the radiation source and depositing them in at least one shielded loading and/or storage station. To remove a radiation source from the loading and/or storage station a traction wire with a coupling effective in the direction of traction is advanced via a fork and a switch into the loading and/or storage station, coupled with the radiation source and withdrawn as far as a stop where it is uncoupled and the traction wire is withdrawn through the fork. To introduce the radiation source into the applicator, on the other hand, a thrust wire having a coupling effective only in the direction of thrust is brought via the fork up to the radiation source and, carrying the radiation source with it, is advanced via the switch into the applicator and withdrawn again leaving the source in the applicator.

A process and apparatus for leak-proof sealing of a metallic capsule closed by a stopper and joining the capsule to a metal cable by arc welding, wherein a capacitor is charged, the capsule with a striking tip at one end or the stopper with an ignition point and the cable are clamped at their ends, connected to the terminals of the capacitor, moved together and welded together by discharging of the capacitor with the formation of an arc.

A process and device for detecting and evaluating surface cracks in workpieces wherein a picture is produced of the surface of the workpiece by means of a video camera and said picture is digitized and is processed by means of a computer to produce a binary picture of any cracks present and a sorting report is triggered when a preselected threshold level is exceeded. In order to obtain a sorting signal that is independent of the absolute brightness of the original picture a blurred background picture is derived from the original picture levels that have been converted to digitized grey shade levels and subtracted from the original picture, the difference picture formed in this way giving the crack representation. A dynamic threshold level for the sorting signal is determined by comparing the grey shade distribution of the original or the difference picture with at least one previously evaluated or difference picture and a binary picture is produced from the original or the difference picture and the grey shade threshold, and picture elements with their gray shades exceeding the set threshold are indicated as defects. The surface of the workpiece may be pre-treated by the magnetic powder or dye penetration process and/or contrast intensifying means.

In a process for monitoring a device for automatically detecting and evaluating surface cracks by means of magnetic powder or the dye penetration process comprising an image pick-up camera and a digital image processing and control unit, a typical defect pattern is projected by means of a projector onto the surface of the article to be examined in the pick-up region of the image pick-up camera and registered, and a defect indication is triggered if the device ceases to operate reliably.

Process for monitoring a device for automatically detecting and

A process and device for producing a radiographic image of a body employ a source of high-energy radiation arranged on one side of the body and a pick-up device arranged on the other side of the body, a real-time system for reproducing the radiographic image having a television camera and a screen, and a computer-tomograph to evaluate the radiographic image row-wise and to display a cross-section of the radiographed body on the screen. By means of the real-time radiographic image a cross-section is selected and represented computer-tomographically. In this manner in the real-time radiographic image the location can be determined of which a layer image is necessary in order to recognise defects in the body being radiographed.

Process and device for producing a radiographic image

A magnetic coupling for translatorily movable bodies that is made in one position, is arranged so that it can be broken, without external control, in another position. For this purpose the first body has a coupling element of permanently magnetic or magnetizable material, the second body has at least one complementary coupling element of permanently magnetic or magnetizable material, and a third body has a coupling element of permanently magnetic or magnetizable material cooperating with the second body. Arranged between the complementary coupling element of the second body and the coupling element of the third body that is a spacer which can be moved as desired between the working positions.
