Abstract: A security element (1) for a security paper, value document or the like, having a carrier (8) which has an areal region (3) which is divided into a multiplicity of pixels (4) which respectively includes at least one optically active facet (5), whereby the majority of the pixels (4) respectively have several of the optically active facets (5) of identical orientation per pixel (4), and the facets (5) are so oriented that the areal region (3) is perceptible to a viewer as an area that protrudes and/or recedes relative to its actual spatial form.

Abstract: A method for producing a microstructure on a carrier by: (a) manufacturing a donor foil by forming an embossed structure with elevations and depressions in a first foil material and applying a transfer layer to the embossed structure, (b) manufacturing an acceptor foil by applying an adhesive layer to a second foil material, (c) laminating the donor foil and the acceptor foil by means of the adhesive layer, the transfer layer on the elevations of the embossed structure bonding to the adhesive layer, and (d) transferring the bonded regions of the transfer layer to the acceptor foil by separating the donor foil and the acceptor foil from each other, thereby forming in the acceptor foil a first microstructure from the transferred regions of the transfer layer, and/or forming in the donor foil a second microstructure complementary to the first microstructure.

Abstract: A security element for a security paper, value document or the like, having a carrier which has a reflective areal region which is divided into a multiplicity of reflective pixels. The area of each pixel is smaller than the area of the reflective areal region by at least one order of magnitude. Each pixel has at least one reflective facet which is formed in a surface of the carrier, and the at least one reflective facet reflects light incident along a predetermined direction on the areal region directionally in a reflection direction predefined by the orientation of the facet. The orientations of the facets of different pixels have a substantially random variation over the reflective areal region.

Abstract: The invention relates to a sterilization testing device comprised of a housing with a test chamber, an indicator placed therein, and with a supply for supplying the sterilization medium. According to the invention, the sterilization testing device consists of at least two housing parts that are matched to one another. A supply channel is made inside the housing part and serves to supply the sterilization medium. The supply channel is configured in such a manner that it forms the base body of the test chamber. The test chamber accommodates the indicator that indicates the completion of the sterilization process. Alternatively to this solution, the invention provides a variant, which is very effective with regard to manufacturing and which permits a quantitative statement regarding the sterilization. Webs are formed inside the housing in the at least partially meandering and/or spiral configuration of the supply channel.

Abstract: The invention relates to a security element for security papers, value documents and the like with at least one microstructure which has a visual appearance that is viewing angle-dependent in transmission, whereby the at least one microstructure is formed from an arrangement of a multiplicity of structure elements with a characteristic structure spacing of 1 ?m or more. According to the invention it is provided that the security element contains at least one motif image which, through the viewing angle-dependent visual appearance of the microstructure, is visible in transmission from certain viewing angles, and invisible in transmission from other viewing angles, and that the microstructure and the motif image together have a thickness of 50 ?m or less.

Abstract: The invention relates to a security element for an article to be protected, having an upper face and a lower face, one or more imaging optical arrangements, which all image a respective associated object to a magnified scale only in front of the upper face, wherein the one optical arrangement or at least one of the optical arrangements comprises a plurality of reflective micro-imaging elements arranged two-dimensionally in a first pattern, and the associated object is in the form of a microstructure object having a plurality of microstructures, which are arranged in a microstructure pattern so matched to the first pattern that the microstructure object is imaged to a magnified scale in front of the upper face by means of the reflective micro-imaging elements.

Abstract: The invention relates to a security element for security papers, value documents or the like, with a carrier having an upper side and a lower side and comprising several reflective first micro-imaging elements flatly arranged in a first pattern, and second micro-imaging elements flatly arranged in a second pattern, a first microstructure object which contains several first microstructures which are arranged in a first microstructure pattern so adapted to the first pattern that the first microstructure object is imaged in magnified form in front of the upper side by means of the first micro-imaging elements, and a second microstructure object which contains several second microstructures which are arranged in a second microstructure pattern so adapted to the second pattern that the second microstructure object is imaged in magnified form in front of the underside by means of the second micro-imaging elements.

Abstract: The present disclosure relates to a wear compensating device for a shoe brake having a brake lever, which brake lever supports a brake lining which acts on a brake body, and which brake lever is adjustable by an actuating arrangement about a main axis between a braking position and a releasing position. The wear compensating device has a first adjusting device which is arranged on the brake lever and which acts on a stop in such a way that the latter, as an actuating travel delimitation, acts on the first adjusting device and therefore at the same time on the brake lever and defines a corresponding releasing position.
