Patent DE-4310660-A1 (DE)
Title: 3-lens apochromat having optical glasses (FC-objectives)
Inventor: LAUX UWE DIPL ING
IPC: G02B9/12
Filed: 1993-04-01
Abstract: The invention relates to apochromatic objectives where a fluorophosphate glass is used as special medium instead of calcium fluoride (fluorite). The objectives are compact objectives, that is to say all three lenses are interconnected, be it by means of a rigid cement-like medium or by a viscous (semifluid) oil-like medium. As a result of this connection of the lenses (components) the system has only two glass-air boundary surfaces and thus has extremely little stray light, however degrees of freedom get lost for the correction. There being only four radii, too few parameters are available for correcting chromatic aberrations (colour errors), spherical aberrations (aperture aberrations) and isoplanasie (comatic aberrations). Therefore, when selecting the optical glasses, care has to be taken that they have the corresponding optical parameters in addition to a protective effect for the fluorophosphate glass. These optical parameters cannot be determined by means of a simple determination of the refractive power.
Patent DE-4315706-A1 (DE)
Title: Method for bending metal sheets and a bending press for carrying out the method
Inventor: VACLAV ZBORNIK
IPC: B21D5/02
Filed: 1993-05-13
Abstract: The present method for bending metal sheets employs a bending apparatus which has a die (10) and a bending punch (13) which penetrates into the die and is secured on a ram (12). To form seaming grooves, the portion of sheet metal forming the outer groove wall is prebent to give a sharp front edge (8) with the aid of said bending apparatus. The sharp front edge (8) is then pressed flat, for which purpose an additional pressing tool (20) with a hold-down device (21) inserted temporarily between the ram (12) and the die (10) of the bending apparatus is used. In this way, the pressing tool can be operated in a manner largely independent of the bending apparatus. Moreover, the use of a pressing tool with a hold-down device improves the accuracy with which the seaming groove is formed. <IMAGE>

Title: Process and apparatus for producing a building material
Inventor: GOETZ ROBERT
IPC: B29B13/02
Filed: 1993-09-01
Abstract: The invention relates to a process and an apparatus for producing a building material for road building, for lightweight building elements or the like. The known building materials, such as crushed stone, gravel, sand or the like, are not available everywhere, so that high transporting costs are incurred not only because of their weight but also because of the distance. The object of the invention is to be seen as that of developing a process by which it is possible to produce a building material which is capable of replacing the building materials mentioned and which can be produced with a significantly lower weight from plastics. This object is achieved by reusable materials, such as containers, films or the like, preferably of PP (polypropylene), PE (polyethylene), PS (polystyrene) or of similar materials, initially being comminuted and subsequently being heated until they plastify, the mixed viscous composition being cooled, followed by breaking up of the cooled-down composition.

Title: Distance plate unit for ski bindings
Inventor: BOEHM ALFRED
IPC: A63C9/00
Filed: 1994-02-03
Abstract: The unit comprises a rear distance plate between heel binding and top of ski and a front distance plate between toe binding and top of ski. A relatively bending-resistant plate-like flat projection (7) is provided on the preferably rear distance plate and projects into a recess on the other distance plate (4) so that the projection interacts with a damping or force-locking action with this latter plate during bending of the ski ends up and/or down. An additional resistance has to be overcome at least in areas during the distortion of the middle areas of the ski which occurs as the ski ends bend up or down.  The projection of the one plate can interact with the other plate through friction locking.  The surface pressure between the slide faces of the projection and the counter slide faces of the other plate can be variable in dependence on the path.
