Abstract: A device with an extraction fan for use for drawing off ambient air loaded with harmful substances during, e.g., laser surgery or HF surgery, is passed through a filter device. For routine use, easy replacement of the filter should be possible, its loading time is prolonged, and the arrangement of the filter does not compromise the easy handling of the suction line. To achieve this, a transparent sleeve 6, into which a cylindrical folded filter 10 is pulled via a perforation support tube 26, is installed in the suction line, or the filter has a hole 29 provided with a support lining, so that the filter can be directly attached to the suction-side connecting branch 5. The filter 10 is flown through radially, and thus it offers a large filter surface at minimum extension.

Abstract: The center has, on its cylindrical wall, adjacent longitudinal rows of slots (3) which are elongated lengthwise, the slots of one row being staggered--generally by half a pitch--with respect to those of the contiguous rows, so that the longitudinal edges of each slot (3) can be brought closer together in the intermediate zone, allowing a substantially uniform reduction in the transverse section of the center when the cylindrical wall of the center is subjected to centripetal pressure under the action of the turns of the wound yarn; an extension (5) projecting into the slot (3) constitutes a spacing element to limit the amount by which the longitudinal edges are brought closer together in their intermediate zone.

Abstract: A mechanised ballistic target presents a hinged target plate which is knocked down out of sight when hit by a bullet and the shock of the bullet impact on the plate is absorbed pneumatically by a rubber suction cup which the plate strikes; the suction cup has an air leakage passage defined by a capillary tube which sets a time delay before the suction cup releases the target plate to allow a spring to return the target plate to a ready position for the next shot.
