Abstract: A hand tool (1) for separating a deep-drawn jaw-spanning dental apparatus such as an aligner or a bite splint of thermoform film. The hand tool includes a grip (2) for holding; a separating element (3) for thermally separating the deep-drawn thermoform film and refining the separated deep-drawn thermoform; a heating device adapted to regulate heating of the separating element (3) so as to increase the temperature of the thermoform film substantially to at least its glass temperature; and a power supply device for supplying electric power to the heating device.

Abstract: A computer-implemented method of planning of the shapes of free-form tool paths (P) for simultaneous two-sided machining of a dental restoration (1) having an individual free-form target geometry from a workpiece (2) by using a dental tool machine (3) having at least two tool spindles each having at least one tool (4) arranged on a different side of the workpiece (2) which is simultaneously movable along an axis (y) relative to the tools (4) thereby imposing a kinematic axis coupling. The method includes a step of determining transformations (T?, T?) of the target geometry by which the kinematic axis coupling is converted into a common coupling parameter for both tools (4); and a step of generating dependent on these transformations (T?, T?) the shapes of the free-form tool paths (P) in which the common coupling parameter is identical in time for all participating tool spindles that are driven simultaneously.

Abstract: A device for separating a deep-drawn jaw-spanning dental apparatus such as an aligner or a bite splint of thermoform film that includes: a separating element for thermally separating the deep-drawn thermoform film and simultaneously refining the separated deep-drawn thermoform film; a heating means for regulating the heating of the separating element so as to increase the temperature of the thermoform film substantially to at least its glass temperature; a support for supporting the deep-drawn thermoform film relatively movable with respect to the separating element; a moving mechanism for moving the separating element along a separation contour of the deep-drawn jaw-spanning dental apparatus relative to the support; and a control unit adapted to control the heating means and the moving mechanism based on the separation contour.

Abstract: In draft deflectors for motor cars with a folding roof which include transversely extending members, such as a roof cross-member. The draft deflectors are formed on safety padding elements, such as frame padding or headrests associated with the interior of the vehicle, or as parts of the padding which, mounted so as to be pivotal about transverse axes of the vehicle, may be opened out from a rest position into an operating position.

Abstract: A typewriting/document editing system includes a signal encoding keyboard for serially entering alphanumeric and control key information characterizing a document being typed into one track of a plural track magnetic storage tape under central processor-stored program control. Each storage record includes an assembled processed line of text augmented by administrative character fields.When document editing is required, all changes (e.g., deletions, insertions, substitutions, text relocations, and the like) are entered on a batched basis in an edit tape track. The stored text records are then marked with appropriate change descriptions ("Pass 1" operation), and the marked information and edit tape tracks compiled to form the desired revised text which is stored on a second tape ("Pass 2" operation). The revised text may thereafter be derived as desired by automated power typing.
