Patent DE-3817066-A1 (DE)
Inventor: CREIYAUFMUELLER PETER
IPC: B65D43/06
Filed: 1988-05-19
Abstract: The upper container rim (12) of a container which, like the lid (11), is made from plastic, for example a container for refrigerated products (10), is formed from two flanges (13, 14) which converge in an upward-directed point (15) and which are inclined in the same direction or different directions relative to the vertical. In the transition region between the inner flange (13) and the container wall (16) a peripheral groove (17) is provided, which is open towards the inside of the container. The lid (11) possesses a closing flange (18) and a bearing flange (20) adjacent thereto and forming a transition into the lid wall (21). The closing flange (18) and bearing flange (20) bear sealingly on the flanges (14, 13) of the container rim (12). By means of a latching web (19) on the one hand and a beading (22) on the other hand the lid (11) is latched relative to the outer flange (14) or within the groove or channel (17). <IMAGE>

Patent DE-3823590-A1 (DE)
Inventor: SCHALLY ANDREW V PROF
IPC: A61K38/00
Filed: 1988-07-12
Abstract: The present invention deals with LHRH antagonists which possess improved water solubility and while having the high antagonist potency of the basic peptides, are free of the edematogenic effects. These compounds are highly potent in inhibiting the release of gonadotropins from the pituitary gland in mammals, including humans. The compounds of this invention are represented by the formula X-R1-R2-R3-Ser-Tyr-R6-Leu-Arg-Pro-R10-NH2 wherein X is an acyl group derived from straight or branched chain aliphatic or alicyclic carboxylic acids having from 1 to 7 carbon atoms, or H2N-CO, R1 is D- or L-Pro, D- or L- DELTA 3-Pro, D-Phe, D-Phe(4-H1), D-Ser, D-Thr, D-Ala, D-Nal(1) or D-Nal (2), R2 is D-Phe or D-Phe(4-C1) R3 is D-Trp, D-Phe, D-Pal(3), D-Nal(1) or D-Nal(2), R6 is D-Cit, D-Hci, D-Cit(Q) or D-Hci(Q) and R10 is Gly or D-Ala where Q is lower alkyl of 1-3 carbon atoms and H1 is fluoro, chloro or bromo, and the pharmaceutically acceptable acid addition salts thereof and methods of use pertaining to these compounds.

Title: Pediplast strip
Inventor: LAMPE GERHARD
IPC: A61F13/06
Filed: 1988-06-29
Abstract: Ingrowing or ingrown toe nails, especially of the big toes, are very painful for the affected patients. There have hitherto been various attempts, even surgical, to prevent this. However, the results have been unsatisfactory. Due to its special shape and the oblique lateral tension exerted by it on the nail wall, the healing promoter PEDIPLAST strip causes the nail edge to grow unimpaired out of the nail wall region. This permits the affected patient to walk without pain.
Patent DE-3826948-A1 (DE)
Title: Method of utilising roofed free spaces and balconies throughout the year
Inventor: WEBER HILAR
IPC: E04B1/00
Filed: 1988-08-09
Abstract: Just as the patio in the case of a bungalow provides a pleasant area between house and garden, balconies on high-rise residential buildings serve as a link with nature. The utilisation of such free spaces is usually completely prevented during the cold season. Rain, snow and frost forces a retreat into the closed rooms of the house. Although permanent glazing would considerably improve the utilisation of such outdoor spaces, its value for utilisation in the summer would be highly impaired due to the hothouse climate and the separation from outdoor air. The solution to the problem provided by the innovation is based on the fact that, in terms of the method of the innovation, the predominantly transparent shut-off means for the outdoor space is arranged temporarily, i.e. only for the cold period of the year, with special securing elements (bracing load-bearing members and slide springs). Consequently, on the one hand, the known advantages of utilisation in the summer remain undiminished and, on the other hand, this results, in the cold season, not only in space-utilisation advantages, but also in the extra benefit of solar heat and a reduction in the transmission-heat loss and an improvement in soundproofing.
Patent DE-3830064-A1 (DE)
Inventor: BERDAHL DONALD RICHARD
IPC: C08G73/10
Filed: 1988-09-03
Abstract: Polyetherimide precursor compositions are prepared by blending a mixture of at least two diamines selected from p-phenylenediamine, m-phenylenediamine and 4-aminophenyl ether with esterifcation product of a low molecular weight alkanol such as methanol and a phony ether tetracarboxylic acid dianhydride preferably 3, 4-dicarboxyphenyl ether dianhydride. Sad polyimide precursor compositions may be converted to polyimides useful in composite formation, by gently heating to remove excess alkanol and subsequently baking at temperatures in the range of about 275-375 DEG C.
Patent DE-3834266-A1 (DE)
IPC: E04C5/07
Filed: 1988-10-08
Abstract: A rod-shaped tension member formed of fiber reinforced composite material is utilized as an anchoring rod in foundation and mining construction, or as a reinforcing member in concrete and prestressed concrete construction. At least, in an axially extending region where it is to receive an anchoring member, such as a rod, the tension member has a continuous helical thread formed of alternating ribs and recesses. The anchoring member has a corresponding thread so that it can be screwed onto the tension member thread. An intermediate layer is provided between the threaded regions of the tension member and the anchoring nut, and is formed of a material affording large plastic deformation relative to the tension member when slight stress increases occur at overload conditions. Accordingly, between the threads on the tension member, and the nut, the plastically deformable intermediate layer has a strength less than that of the fiber reinforced composite material whereby it is subject to compression, acting transversely of the rod. As a result, stress peaks in the tension member are avoided by the plastic deformation of the intermediate layer.

Title: Electrical switch, especially a reversing switch for the drive of a motor vehicle
Inventor: NEUBAUER WALTER
IPC: F16H59/10
Filed: 1989-03-04
Abstract: A reversing switch for the drive of a motor vehicle has a housing, a switching element and a switching lever, which can be pivoted horizontally, between a plurality of positions, with the switching element about an axis which is fixed relative to the housing, a switching lock being provided for at least one position of the switching lever, preferably for a neutral position located between the two operating positions, so that the switching lever cannot be moved out of the locked position until pivoting occurs parallel to the axis. In order that it is impossible to influence the electrical contacts by the additional movement of the switching lever, the switching lever is mounted on the switching element such that it can rotate about a second axis running at right angles to the first axis, its lock can be overcome by pivoting about this second axis, and the electrical contacts can be operated via the switching element, by pivoting said switching element around the first axis.
