Abstract: A heat transfer apparatus is provided, comprising a fluid-tight first housing and at least one fluid-tight second housing, wherein the at least one second housing is arranged in the first housing, a fluid-tight third housing is arranged in the at least one second housing, a first medium flow is guided between the first housing and the at least one second housing, a second medium flow is guided in the third housing, the heat transfer apparatus comprises a heat storage device with a heat-conducting medium, the heat storage device is arranged between the at least one second housing and the third housing, and wherein the heat storage device is in thermal contact with the at least one second housing and the third housing.

Abstract: A holding device for fastening a laser instrument, in particular to a magnetic construction, a pipe, a wall rail and/or ceiling rail, and/or a wall, is disclosed. The holding device includes a basic frame, a receptacle device connected to the basic frame to accommodate the laser instrument and a fastening apparatus connected to the basic frame with a first fastening device. The first fastening device is configured to be rotatable around an axis of rotation relative to the basic frame from a first position into a second position.

Abstract: An optical mount (1) for optical component (2) which has a edge contour (4) relative to extending radially optical axis (A), includes a rigid optical support (3) having an axially oriented stop edge (5), which is suitable for an axial contact with the optical component (2), and at least one flexible spring element which is arranged radially outside the stop edge (5), extends axially on the component side and is curved radially inward. The radial spring element passes at an axial distance from the stop edge into a circumferentially closed jacket sleeve an inner contour (8) of which extends farther radially than the edge contour (4) of the optical component (2).
