Inventor: GESSNER ULRICH
IPC: E05D15/06
Filed: 1991-04-12
Abstract: The subject of the invention is a rolling aparatus (1) for sliding doors (6) or the like especially suspension-mounted thereon, with an undercarriage (2) having at least one running roller (3), with a threaded bolt (7) arranged fixedly on the undercarriage (2) and with a supporting device (10) mounted vertically adjustably on the threaded bolt (7) and intended for the sliding door (6), there being mounted on the threaded bolt (7) by means of an appropriate internal thread (14) a bush (13) which is rotatable relative to the threaded bolt (7) and relative to the supporting device (10). To develop the known rolling apparatus further, in such a way that the vertical-adjustment device can be actuated more easily, it is proposed by the invention that there be arranged between the bush (13) and the supporting device (10) a ball bearing (12) or the like which consists of an inner bush formed by the bush (13) and of an outer ring (17) arranged fixedly on the supporting device (10), between which inner bush and outer ring the balls (18) or the like are arranged, the supporting device (10), the bush (13) and the ball bearing (12) being held positively in one another in such a way that the supporting device (10) is supported on the bush (13) via the ball bearing (12). <IMAGE>

Title: Appts. for prodn. of laminar tubing - has stacked rings profiled to feed separate plastic melts from bores through homogenising bores to join other melts in main tubing bore
Inventor: COLLIN BALDHAM DR ING
IPC: B29C48/10
Filed: 1991-05-10
Abstract: Appts. for the production of laminated plastic tubular films or pipes has one or more rings to feed the plastic materials for the different layers. The rings are concentric round a mandrel and feed the materials into a laminar bore which forms the tubing/piper. Each ring has a feed bore, an annular gate into the laminar bore and at least one distributing bore from which its material emerges radially at the side. Each distributing bore supplies a ring of material entering the feed bore, and the cross-section of each distributing bore narrows down in the direction of flow. ADVANTAGE - The design eliminates the existing problems of e.g. pressure build-up in the feed bores, difficulty in cleaning, separate nozzles and barrels for the individual layers, difficulty in maintaining feed gaps to close tolerances, varying density and pressure in the individual flow streams, and nozzles with large weight/high cost/complicated assembly and cleaning/long flow paths/risk of decomposition of sensitive materials.
Patent DE-4116950-A1 (DE)
Inventor: VOGTEL PETER DIPL CHEM DR
IPC: B01D53/56
Filed: 1991-05-24
Abstract: A process for reducing NOx emissions in the thermal reaction (combustion) of nitrogen-containing fuels or in the reduction of nitrogen oxide-containing exhaust gases or exhaust vapours provides a stepwise reaction, a reduction of all present or forming NOx fractions being carried out in a first step in the substoichiometric fuel/ oxygen ratio and a secondary reaction being carried out in a subsequent second step or in a plurality of subsequent steps to give complete conversion of all oxidisable reactants. To accelerate the reaction it is proposed that in at least one of the reaction steps, the reaction partners are additionally activated by activation regenerators, which statically mix the reaction partners together and contribute to the heat flow balance. To carry out the process, a furnace is provided which is equipped in the interior with a regenerator wall having through-holes.
