Abstract: A track cover comprising slab-shaped cover elements (7) arranged between the rails (3) of the track (2) on rail level and, preferably, also slab-shaped cover elements (8) outwardly adjoining the rails (3). The cover elements (7, 8) comprise supporting bodies (9) at their rims (10) which face the rails (3), the cover elements resting on the rails (3) by means of these supporting bodies. The supporting bodies (9) which are arranged on the cover elements (7, 8) at their rims (10) that face the rails (3) are mounted on these cover elements so as to be shiftable in the rail-longitudinal direction (11). It is suitable if on each rim (10) of the cover elements (7, 8) that faces a rail (3) which is provided with the cover, at least two supporting bodies (9) are shiftably arranged. Preferably, the supporting bodies (9) are mounted to be shiftable in the rail-longitudinal direction (11) and to be pivotable about a geometric axis extending in parallel with the displacement direction.

Abstract: The compounds of the formula (I) in which R1 represents hydrogen or in each case optionally substituted alkyl, alkenyl, alkynyl or phenyl are highly suitable as microbicides for protecting plants and materials.

Abstract: A noise control device for tracks (1) comprising sound-absorbing slabs (3) mounted at the rails (2) of the track (1), the slabs being supported on the rails (2) via elastic sections (5) and self-supportingly bridging the space between the rails (2). To improve silencing of the slabs (3) it is provided for the slabs (3) to be comprised of particles (9) of porous lightweight building material, which are combined by a binder. The slabs (3) have an embedded reinforcement (11). Advantageously, also silencing cavity resonators (14) are formed in the slabs (3). A special embodiment provides for the space between the rails (2) of a track to be bridged by slab parts (3a, 3b) arranged in pairs which are supported on each other at their rims (26, 27) facing each other.

Abstract: A level cover for tracks (1), wherein the space (4) present between the two rails of a track is bridged by slabs (5, 6) arranged in pairs, which slabs are merely supported on the rails (2, 3) and bridge the distance (13) between the rails self-supportingly, the two slabs of the slab pairs being assembled in hinge-like manner. At their facing rims (15, 16), the slabs (5, 6) of each slab pair have carrying portions (17) and resting portions (18) alternatingly following each other in meander-like fashion, the carrying portions being formed by indentations (20) originating from the slab upper side (19) and extending as far as to the rim facing the other slab, upwardly directed indentations (22) originating from the slab lower side (21) being formed below the resting portions (18), which indentations are shaped complementary to the indentations of the carrying portions.

Abstract: In a track whose rails are laterally and downwardly supported on the rail outer side and on the rail inner side via elastic intermediate inserts (4, 6) by longitudinal carriers underneath the head portion (3), the rails (2) extend at a distance above the track structure parts located therebelow. The longitudinal carriers at the rail outer side are first console ledges (5) which are part of a base plate (10) lying under the rails (2), and the longitudinal carriers on the rail inner side are second console ledges (7) which are part of an inner plate (11) lying between the rails (2), which inner plate (11) in turn is supported on the base plate (10).

Abstract: A multi-track road crossing including a roadway positioned at the level of the rails, which roadway is formed by self-supporting slabs, wherein inner slabs (4) are provided which bridge the space between the rails (2, 3) of each track (G1, G2) and are supported on these rails (2, 3), and wherein outer slabs (6) are provided which are supported on the outer side of a rail (2, 3) of the track (G1, G2) by one of their sides (6a) and on a supporting body (10) arranged beside the track by the other one of their sides (6b). In the intermediate region (Z) between two tracks, the roadway is formed by self-supporting compensating slabs (11, 11a) which on both of their longitudinal rims (12) are supported on the supporting bodies (10, 10a) which also support the outer slabs (6) of the respective tracks (G1, G2). The compensating slabs (11, 11a) preferably are polymer concrete slabs, in particular made of polyester concrete.

Abstract: The invention relates to crosslinked polymers based on polyvinyl acylate or polyvinyl alcohol and having crosslinking agent units which are derived from crosslinking agents of the general formulae ##STR1## These products, inter alia, are particularly hydrolysis-resistant and can have high crosslinking densities.The invention also relates to a process for preparing these polymers and to their use in chromatography and as carriers for biologically active substances.

Abstract: The operating elements for adjusting the tilt of the back rest of the rear seat of a motor vehicle shall be disposed in an area which is easily accessible and permits adjustment of the back rest by the passenger in the sitting position during the ride. This is achieved in that the operating elements of the adjuster are disposed in the area of the opening for the center arm rest that can be folded down from the back rest. It is especially advantageous if the arm rest in the folded-up position conceals the operating elements. It is also possible to integrate the operating elements in the center arm rest and to adjust the tilt of the back rest by moving the arm rest up and down.

Abstract: A cinch plug for connection to an electrical cable in audio or video systems has a contact pin and surrounding contact bushing each of which are formed of curved circumferentially disposed axially extending contact springs.

Abstract: An electrical contact device for transmitting high electric current includes a cylindrical contact pin (2) and a spring-loaded contact jack (1) for receiving the pin. A plurality of essentially axially parallel spring-loaded contact elements are provided which extend axially on the cylindrical inner wall of the jack. In order to allow contact over large tolerances between the contact pin (1) and contact spring jack (2), the jack is provided with intermediate spring contact elements (4,5) between it and an outer sleeve body (3) is which the jack is mounted with spring-loading both axially and radially.

Abstract: The invention relates to an outside rearview mirror for mounting on the driver's side of a motor vehicle which is adapted for pivoting movement towards the side of the vehicle operator about an axis which is disposed substantially vertically with respect to the plane of vehicle movement, the pivoting being effected by means of a reversible electric motor, so as to eliminate the glare to the vehicle operator if the headlights of a following vehicle are reflected by such a mirror.

Abstract: A pre-assembled module for the cockpit zone of a motor vehicle, especially a passenger car, which is adapted to be mounted as one single unit inside the vehicle body and which incorporates essentially the following components: an instrument board including all instruments and accessories commonly contained therein, fuse box and electric wiring, heater with controls and air distribution system; furthermore a steering system including steering wheel, steering column enclosure and steering support means; also pedals for clutch and brake, including mounting brackets. The vehicle body includes a fire wall and fire wall support member to which the aforementioned components and accessories are connected when in the installed position. The fire wall and fire wall support member are separated from the body shell and serve as an assembly base for the unit. In the installed position, the fire wall and fire wall support member are sealingly connected with the respective adjacent body panels.

Abstract: A process for the production of contact-spring bushes with a plurality of contact springs curved radially inwardly and clamped on one end in an approximately cylindrical bush body. Initially straight contact springs formed by portions of a contact-spring wire are first introduced into the interior of the bush body and are subsequently, on the one hand, pressed against an annular extension partially projecting into the bush body and located at the front end of a line connection piece and fixed in this position on one end and, on the other hand, elastically deformed radially, in such a way that their other ends facing the pin insertion end of the bush body are guided so as to be freely movable in an annular gap provided between the bush body and an annular body provided in it.
