A track connection element for positioning a track body, which exhibits an interior, on a hanging element is disclosed. The track connection element exhibits two sidewalls, distanced from each other, which both exhibit an insertion section for insertion of the track connection element into the interior and a connection section connecting the sidewalls, which section has a recess for the hanging element. The sidewalls are reduced in terms of height in certain areas in the area of the insertion section. Further, a fastening device with such a track connection element is disclosed.

A line fastening device for fastening a line on a rail body which has a mounting opening is disclosed. The device includes a bracket element that has two spaced-apart legs, each with two rear engagement sections for engaging behind opposing edges of the mounting opening, which are provided on a free end region of the corresponding leg, and with a tensioning device for bracing the line fastening device on the rail body. Each leg has a first leg part and a second leg part that is spaced apart from the first leg part by a gap. The gap extends partially along the leg starting from the free end region of the leg. The leg parts of the leg are spring elastic.

A system for the chemical storage of radiant energy in which either:A. 1,8-diaryl-1a,2,7,7a-tetrahydro-1,2,7-metheno-1H-cyclopropa[b]naphthalenes (1) are converted on heating to 1,2-diaryl-2a,8b-dihydrocyclobuta[a]naphthalenes (2) or 8,9-diaryl-benzocyclooctatetraenes (3), with the release of heat; and exposure of either compounds (3) or compounds (2) to suitable radiation results in the photochemical synthesis of compounds (1); orB. substituted naphthalenes undergo photochemical dimerization to form 1,2,2a,7,8,12b-hexahydro-1,8,2,7-ethanedihylidenedibenzo[a,e]cyclobuta[c]cyclooctenes. On heating, the latter revert to the original naphthalenes with the release of heat.

Add-on components (3) are to be fastened to a support part (5) with a simple technical set-up and without a need for tools, with a device (1) for fastening an add-on component (3) to a support part (5), including at least one movable holding element (16) that, when it is inserted into an opening (10) of the support part (5) due to the contact between the at least one holding element (16) and the support part (5), can be moved into an engagement position so as to be inserted into the opening (10), and that, after it has been inserted into the opening (10), can be moved into a catching position by a return movement of the at least one holding element (16) so that the at least one holding element (16) can catch behind at least one edge (9) of the support part (5) in order to create a positive connection between the at least one holding element (16) and the support part (5), and at least one affixer for affixing the add-on component (3) to the device (1). At least one holding element (16) can be moved from the engagement position into the catching position by at least one elastic element (8).

In order to improve a device for the non-circular machining of workpieces comprising a machine frame, a workpiece spindle held on the machine frame and operated as C-axis for a workpiece to be machined, a Z-slide displaceable on the machine frame in the Z-direction in relation to the workpiece spindle and having a Z-axis drive, an X-axis drive in the form of a linear motor arranged on the Z-slide for advancing a tool in the X-direction towards the workpiece, and a numerical control system for activating the X-axis drive in correlation with the rotation of the workpiece spindle, such that more precise work results are obtained, it is proposed that the linear motor serving as X-axis drive be a three-phase asynchronous linear motor with a primary part fixedly arranged in the X-direction on the Z-slide and a secondary part movable relative to the primary part.
摘要:
A fastening system is disclosed. The fastening system includes a device rail, a holding element mountable on the device rail, and a supporting structure, where the supporting structure defines an opening and includes a gripping surface, and where the opening is an end of an interior space enclosed by the supporting structure. The holding element is insertable into the opening of the supporting structure and, in a back-locking position, the gripping surface grips the holding element.
