Abstract: A wiper device having a wiper arm (20a; 20b; 20c), having at least one wiper blade (18a, 18a?, 18a?) which is coupled to the wiper arm (20a; 20b; 20c), which includes at least one wiper lip (22a, 22a?, 22a?) for wiping a surface (16a; 16b; 16c) of a protective element (14a; 14b; 14c) of a sensor device (12a), in particular of a Lidar device, and having a wiper arm guide unit (24a) which is provided for moving the wiper arm (20a; 20b; 20c) in an at least substantially translatory manner along a guide path (50a). It is proposed that the wiper device has a rotary joint (26a) by means of which the wiper blade (18a, 18a?, 18a?) is pivotably mounted on the wiper arm (20a; 20b; 20c).

Abstract: A wiper device (10a-10f) for wiping a sensor system (30a-30f), in particular a lidar system, with at least one wiper unit (12a-12f), which comprises at least one wiper lip (16a-16f) for wiping a surface (38a-38f) of the sensor system (30a-30f) and with at least one pressing unit (14a-14f). It is proposed that the pressing unit (14a-14f) comprises at least one spring element (24a; 52b; 54c, 56c; 58d; 60e; 62f, 64f) for pressing the wiper unit (12a-12f) against the surface (38a-38f).

Abstract: The invention relates to a lidar device (10a-10l) having a cleaning unit (12a-12l) which has at least one wiper unit (14a-14l) having at least one wiper blade (16a-16l) for mechanically cleaning a cover element (18a-18l) of a lidar unit (20a-20l), and having at least one pressing element (22a-22l) which in a mounted state provides a pressing force for the wiper blade (16a-16l).

Abstract: The invention relates to drospirenone containing film-coated tablet with improved resistance against the environmental influences, especially against atmospheric humidity. The invention further relates to a method for the preparation film-coated tablet cores whereby applying the active agent to the core may be accomplished with increased safety.

Abstract: The invention relates to new 4-chloro-aryloxy-acetyl- or 4-chloro-aryloxy-propionyl-malonates of the general Formula I, ##STR1## a process for the preparation thereof and herbicidal compositions comprising the same.In the general Formula IR.sup.1 stands for chlorine or methyl;R.sup.2 represents hydrogen or chlorine;R.sup.3 stands for hydrogen or methyl;R.sup.4 represents C.sub.1-4 alkyl and the two R.sup.4 groups may be identical or different; andX is --N.dbd. or --CH.dbd..The compounds of the general Formula I may be prepared by reacting a compound of the general Formula II ##STR2## with a metal derivative of a malonate of the general Formula III; ##STR3## or in the presence of an metal compound with a malonate of the general Formula III; or by reacting a compound of the general Formula IV ##STR4## with a compound of the general Formula V ##STR5## (in which Formulae R.sup.1, R.sup.2, R.sup.3, R.sup.4 and X are as stated above; Z stands for halogen and Y represents halogen, cyano or alkylcarbonyloxy).
