IPC: A61K6/06
Filed: 1988-09-13
Abstract: The present application describes a method and the modelling compositions for performing it which is characterised, in particular, in that the models for preparing plastic fittings, e.g. denture base, upper plates, onlays, crowns and bridges of plastic or composites are produced to be larger by the amount by which the dental objects contract on cooling after hot polymerisation.

Title: Improved catalyst technology for the elimination of pollutants from the exhaust gas of internal combustion engines
Inventor: FALKENSTEIN KARL
IPC: F01N3/28
Filed: 1988-11-07
Abstract: The improvement claim for an exhaust gas catalyst for internal combustion engines, appropriately characterised by the use of a catalytic metal oxide, is conceived in such a way that the known disadvantages of hitherto fitted catalyst types with temperature sensitivity, lead sensitivity, exhaust gas back-pressure with a drop in the performance of the engine and increased gasoline consumption are substantially diminished or no longer arise. The exhaust gas catalyst with catalytic metal oxide does not form a compound with the lead from leaded gasoline, as is the case with rare metal catalysts. The oxide catalyst should be located as close as possible downstream of the exhaust manifold, in order to burn the lead content from leaded gasoline to non-poisonous lead oxide, in contrast to the temperature-sensitive rare metal catalyst which must be located at an appropriate distance from the exhaust manifold. For exhaust gas problems of various types, the oxide catalyst is a useful alternative, in particular for the filling station market, so that the existing problem for unleaded gasoline abroad is eliminated.

Title: Heating cushion for toilet seat
Inventor: ROEHNER ERNST
IPC: A47K13/30
Filed: 1989-03-03
Abstract: For many people it is unpleasant, especially in winter, when nature calls and they have to pay a visit to the "smallest room". If sitting on the cold toilet seat causes rheumatic pains, a long "session" can thus be very unpleasant. To remedy this ill, the abovementioned heating cushion has been developed, thus making even a long "session" a pleasure! Various textiles, or deep-pile wool with plastic-foam base, or alternatively various flexible- or ridid-plastic foam materials are suitable for this purpose. The possible attachment of the divided seat cushion to the seat:     1. by means of adhesive strips (Fig. 1),   2. by uniformly distributed suction cups,   3. by rubber bands with snap fastener,   4. by eyes with laces, 5. by fitting holes in the seat and nubs on the underside of the seat cushion (Fig. 2).   <IMAGE>
Patent DE-3909864-A1 (DE)
IPC: B65D41/04
Filed: 1989-03-25
Abstract: The present invention is a seal for a container closure which is characterized by the fact that associated with the sealing lip (3) is an actuating arm (5) by which the sealing lip can be swiveled. The seal is part of a container closure (1) with a side wall (11) and a bottom (15). When the closure is screwed onto a container, the actuating arm is swiveled counterclockwise, this swivelling movement being facilitated by a deliberate attenuation (17) in the region of the bottom (15) of the closure (1). A counterclockwise swiveling movement of the actuating arm (5) also causes the sealing lip (3) to swivel counterclockwise and thus to lie against the outer wall of the container. A sealing surface is created not only between the container and the actuating arm (5), but also between the outside of the container and the sealing lip (3).
