Abstract: A drop hanger for a pipe or similar prismatic object comprises an essentialy U-shaped bearing element (1) whose end parts (4, 5) mate with a fastening element (2) which can be fastened to a threaded rod (3) hanging down from the ceiling. The U-shaped bearing element (1) is made of stiff wire, and the end parts (4, 5) of the bearing element (1) are bent at least inwards. The fastening element is designed as a yoke (2) with an essentialy U-shaped cross section, while the bottom (6) of the U-shaped yoke (2) is partially removed to allow through the threaded rod (3) and the bent end parts (4, 5) of the bearing element (1).

Granted: 1992-02-05
Abstract: An improved, delamination-resistant, cellular retroreflective sheeting comprising: 1) base sheet having a layer of retroreflective elements disposed over one of its surfaces, 2) a polymeric cover film disposed in spaced relation from the layer of retroreflective elements, and 3) a network of narrow intersecting bonds extending between said cover film and base sheet to adhere the cover film and base sheet together and form a plurality of cells within which retroreflective elements are hermetically sealed. The cover film, which comprises a continuous polymeric phase and a discontinuous polymeric phase, is biaxially oriented such that the discontinuous polymeric phase is in the form of minute disks distributed substantially uniformly througout the film. The retroreflective sheeting is resistant to delamination because under the influence of forces that tend to remove the cover film from the base sheet, the cover film is generally removed only at the edge of the sheeting, e.g., from the front row of cells, but no further. Most of the sheeting remains intact and ready for continued utility.

Abstract: The tool holder, consisting essentially of a guide tube (3) and an adjusting sleeve (6) rotatably mounted thereon, has holding segments (7), of roughly U-shaped design in cross-section, for locking the tool (5). In this arrangement, the legs of the holding segment (7), which are designed as locking elements (7a) and driving strips (7b), engage in longitudinal grooves (5b, 5c) of the tool (5). Either the entire holding segment (7) or only the driving strip (7b) can be disengaged radially by rotating the adjusting sleeve (6). As a result, the holding segment (7) plunges into escape niches (6a) on the inside of the adjusting sleeve (6). The position of the holding segments (7) is controlled by a cam (7c) on the outside of the holding segments which interacts with an inner contour (6b) on the adjusting sleeve (6). A catch with a ball (8) and an annular spring (9) secures the adjusting sleeve (6) in the different rotary positions.
