Abstract: A method is described for producing a module to be incorporated in a card body wherein a module carrier is provided with a conductive structure on one side. During production of the module carrier, a material whose properties essential for a certain manner of connection with a layer of material of the card body upon incorporation of the module in the card body are adjusted to said layer of material is used at least for a first layer of the module carrier located on the side opposite the conductive structure.

Abstract: Apparatus for the catalytic conversion of waste gases such as those which accumulate in the synthesis of vinyl chloride is presented in which the waste gases are successively treated at an elevated temperature with a catalyst for oxidative cracking and with a catalyst for oxidative afterburning.

Abstract: A plastic straddling or expansion plug having a closed plug neck and a closed plug foot both with a longitudinal aperture into which a screw can cut a thread. The plug includes a shank having a thin plug jacket on which a two-flight helix is integrally formed. In the region between the helices, the plug jacket is provided with longitudinal slits. On the outside of the helix, further ribs are provided which each extend over a 180.degree. arc and are integrally formed with the helix, alternating in orientation by a 90.degree. angle. The plug neck includes flange lugs oriented in the shape of a cross and adapted to be folded over.

Abstract: The specification describes an expanding masonry attachment plug, whose plug head has a wide insertion hole and whose shank, provided with a through hole, is divided by longitudinal slits into expanding segments. The latter join at the far end to form a plug foot. To enable use of the plug both in dense masonry material and also in light weight building materials the plug has the following features. Internally the expanding segments delimit a guide hole adapted to bring about expansion, with a diameter which is less than the diameter of the appropriate screw. The plug foot consists of a closed sleeve adapted to bring about a bending outwards of the expanding segments by axial compression or clamping of the shank, with a through hole for the cutting of a tension thread on complete driving of the screw into position.
