Patent DE-2805047-A1 (DE)
Title: Machine tool slide clamp - has two locking bars on spindle and studs supported tube
Inventor: GUETH HELMUT
IPC: B23Q1/28
Filed: 1978-02-07
Abstract: The clamp of machine tool slide ensures a reliable locking without causing a symmetrical loading, and thus results in square positioning of the slide with respect to the feed direction. Actuation of the clamping spindle (5) shifts the two bars (6/7) towards the clamping surfaces (8/9) of the machine slide (1). The movement provides a symmetrical thrust, and the whole mechanism acts as a closed system which compensates nonparallelism of clamping surfaces (8/9) and of the slideways (2/3). The clamping forces are taken up by tube (12) and thus eliminates force transfer to the machine bed (4).

Title: Weld beading removal from corner of window frame - by slicing knives and two alternative milling tools for different profiles
Inventor: EISENBACH BERNHARD
IPC: B23C3/12
Filed: 1980-05-31
Abstract: The parent patend describes an appts. for removing projecting weld beadings from the corners of plastics or metal window frames or other frames. A basic frame, esp. a vertical plate, has one or more trimming knives for slicing off the projecting weld beading on the front and back faces of the window frame; these knives move longitudinally on the support plate. In addn., to trim the beading from the profiled corner of the frame, a revolving milling tool is mounted on a support, which can also move longitudinally in only one direction on the support plate, to bring it into contact with the mitred corner of the window frame. In the addn., the guide seating or slot for the window frame possesses two limit switches, which sense the corner of the window frame at two different levels. With a milling tool comprising two separate milling heads for different profiles of the window frame, the two limit switches ensure that the milling tool is not brought too close to the corner of the window frame if the incorrect milling head is in position. Thus the spoiling of the frame by use of the wrong milling head is automatically prevented.
