Patent DE-3406798-A1 (DE)
Title: Luminescent material for X-ray picture persistent screens
Inventor: DEGENHARDT HEINZ DR RER NAT
IPC: C09K11/84
Filed: 1984-02-24
Abstract: To take X-ray pictures, storage layers (16) are used which retain signals of emitted pictures. The stored pictures may, for example by scanning by means of a laser beam, be released again with the emission of light and be made accessible. This requires a luminescent material for storage, which material is chemically stable with regard to environmental influences and yields a high signal upon stimulation by illumination. The storage material of this type provided by the invention is yttrium oxisulphide (Y2O2S) which contains europium (Eu) and bismuth (Bi) as activators corresponding to Y2O2S:Eu:Bi, in which the Bi may be replaced by antimony (Sb) or thallium (Tl). This persistent luminescent material is especially suitable for persistent screens which are used in X-ray diagnostics for producing radioscopic pictures. <IMAGE>

Patent DE-3409968-A1 (DE)
Title: Single-lever mixing battery to be connected to a low pressure water heater
Inventor: KOPPANEN JORMA TAPANI
IPC: F16K11/078
Filed: 1984-03-19
Abstract: In the mixing battery, the regulation of the cold and hot water takes place by means of two cooperating ceramic plates provided with openings. The mixing battery is connected to a low pressure water heater such that only cold water flows to the mixing battery, and a portion of it is conducted directly to the outflow for the mixed water by means of the regulating plates, while a portion of water of desired volume is conducted via the water heater and back into the mixing battery and to the outflow for the mixed water. In this form of application the problem arose with the already known lever mixing batteries that the construction of the "normal mixing battery" had to be considerably altered in order to limit the flow pressure resulting in the heater. This is avoided according to the invention in that an inlet seal is arranged at the cold water inlet point and is equipped with an elastic component which alters its shape in dependence on the flow pressure of the water flowing in and which limits the inflow opening and prevents the occurrence of an excessive pressure in the water heater.

Title: Fitting for convertible sofa
Inventor: POSCHINGER GUSTAV
IPC: A47C17/207
Filed: 1984-06-01
Abstract: In a convertible sofa, a cushion 5 is attached by means of a fitting on a carriage 4 below a cushion 2. The fitting has a connecting rod 6 which is connected to the cushion 5, a web 7 connected to the carriage 4, a rigid connection 8 and two members 10 and 11 connected by a joint 9. The mutual pivoting movement of the members 10 and 11 is bounded in one direction by a stop 12. In order to move the cushion 5 next to the cushion 2 to form a double bed, the carriage 4 is pulled out and the cushion 5 is moved into its pivoted-up position as in a known spring fitting, such that it is possible to gain access to the bedding compartment provided in the carriage 4. By means of pressure exerted downwards onto the edge of the cushion 5, the members 10 and 11 pivot into an angular position relative to one another so that the cushion 5 then moves into a horizontal position. The fitting thus allows both the function of a normal spring fitting and the movement of the cushion 5 into an elevated horizontal position. <IMAGE>

Title: Turbine wheel unit for generating power under water
IPC: F03B17/06
Filed: 1984-06-05
Abstract: The unit consists of a pipe of large diameter. Mounted rotatably on the topside thereof are turbine wheels which are directly or indirectly connected in terms of rotation to dynamos mounted in the pipe, a regulator controlling the appropriate speed of the dynamo. The pipe can be anchored together with the device in a base which is provided in the river bed. It can thus be mounted in a supercritical flow without having to fear that damage will occur due to the strong flow. The turbine wheels are encapsulated on one half-side, so that the flow covers only one half-side of the drive of the turbine wheels. The pipe has a diameter appropriate to enabling a fitter to work therein in comfort. The power produced is fed to the points of use from the pipe by means of cables. <IMAGE>

Title: Verfahren und Einrichtung zum Kontrollieren von Schlacke in einem Vorratsbehaelter beim Stranggiessen von Metall,insbesondere von Stahl
Inventor: BROCKHOFF REINER DIPL-ING
IPC: B22D11/18
Filed: 1984-08-20
Abstract: Ein derartiges Kontroll- bzw. Meßverfahren dient dem Zweck, das Eindringen von Schlacke (3) in die Stranggießkokille (8) und damit in den Gußwerkstoff letztlich zu verhindern. Die Feststellung, ob Schlacke (3) von einem der Stranggießkokille (8) vorgeschalteten Vorratsbehälter (5) in den Gießstrahl gelangt, ist schwierig, solange das verdeckte Gießen beim Stranggießen angewendet werden muß. Das verdeckte Gießen erlaubt z. B. keine optische Erkennung der Schlacke von außen. Aufgrund des Vortex-Effektes im Kern eines Gießstrahls mitgeführte Schlacke kann ebenfalls nicht optisch erkannt werden, solange auf Reoxidationsschutzeinrichtungen nicht verzichtet werden kann.  Um das Eindringen von Schlacke (3) aus der Gießpfanne (1) in den Vorratsbehälter dennoch zu erkennen, wird vorgeschlagen, daß eine kontinuierliche Messung des Gewichts des Vorratsbehälters (5) mit Schmelzeninhalt durchgeführt, daß ferner zeitparallel eine kontinuierliche Messung der Schmelzenspiegelhöhe (12) im Vorratsbehälter (5) vorgenommen wird und daß darauf basierend eine Abweichung vom spezifischen Gewicht der Metallschmelze nach unten ermittelt wird.

Patent DE-3516325-A1 (DE)
Title: Hospital bed having a resting surface of adjustable height and inclination
Inventor: DEHNE HEINZ
IPC: A61G7/015
Filed: 1985-05-07
Abstract: In a hospital bed of the type specified in the main patent (patent application P 3516092.6), an extremely stretched position of the components belonging to the lifting linkage, specifically the lifting arm and the flap, is to be avoided. Movement of the lifting linkage is triggered by a push-out member of the drive motor. The push-out member acts upon the shaft in the subframe which is connected so as to be fixed against rotation with the first lifting linkage and whose rotation is transmitted via the coupled toothed rack to a second shaft which is connected so as to be fixed against rotation to the other lifting linkage. At the same time, besides an extension actuator, the drive motor possesses a run-in actuator for its push-out member. The invention proposes that a control linkage connected with the run-in actuator be used whose sensor end delimits the rotational movement path of the bearing pin used for coupling the toothed rack. The rotary movement of the bearing pin is brought about by rotation of the second shaft. The bearing pin is kept in a final position in which the associated, second lifting linkage assumes a still tolerable limit position before reaching the stretched position of its lifting arm and its flap.

Title: Internal combustion engine with exhaust turbocharger
Inventor: STULLE OTTO DIPL ING
IPC: F02B37/20
Filed: 1985-07-25
Abstract: In an internal combustion engine with an exhaust turbocharger a vaporisation chamber is arranged in the wall of the exhaust pipe immediately upstream of the turbine or in the wall of the turbine housing, into which chamber water is injected, which is vaporised by the heat of the wall and leaves the chamber in the form of a jet of hot steam, which strikes the turbine blades as directly as possible. In this way, on the one hand, an increase of the mass flow is achieved without energy essentially being extracted from the exhaust gases, and in addition the kinetic energy of the jet of hot steam is used to drive the turbine wheel. Finally, cooling of the turbine blades is achieved by means of the hot steam, thereby increasing the service life of the turbine.
