Abstract: A flame protection apparatus for a burner, in particular in a drying drum, in particular in an asphalt facility, has a central longitudinal axis and a plurality of plate fins which are arranged in a circumferential arrangement in the circumferential direction with respect to the central longitudinal axis, wherein plate fins that are arranged adjacent to one another in the circumferential direction are sealed by means of a circumferential gap seal.

Abstract: A flame protection apparatus for a burner, in particular in a drying drum, in particular in an asphalt facility, comprises a central longitudinal axis and a plurality of lifter plates, which are arranged in the circumferential direction with respect to the central longitudinal axis, wherein at least one plate fin holder for holding a plate fin is detachably fastened to each of the lifter plates.

Abstract: A method for detecting critical transverse movements. The method includes the following steps: emitting a CW radar signal and generating radar data based on the received reflected CW radar signal with the aid of a radar device; ascertaining collision-relevant spectral ranges of the radar data as a function of an ego velocity of the radar device; ascertaining a time dependency of a relative velocity and of an object angle of an object by evaluating the radar data in the ascertained spectral ranges; and detecting a critical transverse movement of the object using the time dependency of the relative velocity and of the object angle of the object.

Abstract: A positioning apparatus that includes at least two rails, at least two work carriers, and a drive unit. The at least two rails (1) are arranged next to one another and have longitudinal directions. The at least two work carriers (2.1-2.n) are arranged on each rail (1) in such a way as to be traversable one behind the other in the longitudinal direction of the rail (1) and are able to be fixed independently of one another in selectable positions. The work carriers (2.1-2.n) traversable on the rails (1) are arranged next to one another so as to allow traverse drive of only one of the work carriers (2.1-2.n) on the rail (1) so as to form an independently driven work carrier that carries along at least one non-independently driven work carrier (2.2-2.n). The drive unit (5, 15) is provided on the rail (1) and/or on the driven work carrier (2.1).
