Title: Mounting device for a transportable valuables container
Inventor: HIRSCHSON RICHARD
IPC: B60R7/02
Filed: 1981-03-02
Abstract: To make a transportable valuables container theft-proof, a holding device is used which can be mounted on a fixed surface, for example in a car, by means of releasable fastening devices (especially screws). The valuables container, which is provided with a locking device, fits into, is connected to and, if necessary, is removable from the said holding device. In order to prevent the unauthorised removal of the holding device together with the valuables container from its fixed position by subsequent release of the screw devices, the holding device takes the form of a "U-shaped body" which is adapted to the dimensions of the valuables container and the side walls of which have outwardly bent screwing-on surfaces on their free ends, which surfaces interact with surfaces which are unreleasably arranged, parallel to and at a distance from one another, on the side walls and also have surfaces which are bent outwards, the interaction being such that the screw positions are positively covered and are therefore inaccessible from the outside after insertion of a special filling piece, which respectively fits between two bent surfaces of a side wall.
Patent DE-3109607-A1 (DE)
Title: Dedusting for furnaces
Inventor: LUETTGER HANS
IPC: B04C3/00
Filed: 1981-03-13
Abstract: In all known centrifugal dust separators, there are sometimes difficulties in matching the dedusting performance to current requirements. This applies in particular to small furnaces having an output between 0.5 and 10 Gcal/h and the associated dedusters. According to the invention, a significant increase of the dedusting performance of centrifugal dust separators is achieved by using cold gas and/or flue gas as a spinning agent. In this case, not only can, in broad ranges, any desired spinning motion be generated, but, as a consequence of the gas admixture, a flue gas cooling occurs which considerably promotes the dedusting. This is due to a reduced viscosity of the flue gases.
Patent DE-3110325-A1 (DE)
Inventor: OPITZ HEINRICH DIPL CHEM
IPC: G01P13/00
Filed: 1981-03-17
Abstract: For the recording of local boundary-layer flow-line directions in liquid media by means of a photographic layer, (a) small reagent depots or deposits, with a volume of about 0.2 mm3, of a water-soluble substance reactive to silver ions ("chemical flow line indicators") are applied in raster fashion to the surface which is to be exposed to the flow and which surface is previously coated with a dry or swelled photographic sheet film, (b) the reagent deposits are covered with an inert layer which is soluble in the liquid flow medium, (c) the surface so prepared is exposed to the flow of an aqueous flow medium, and (d) the film is developed according to conventional means. The reagent deposits, which may be present as a paste, can contain a precipitation agent for silver ions. The deposits can be applied as a dot raster to the surface which is to be exposed to the flow (and which is coated with a photographic film) by means of screen printing or by means of a hole raster template. The method permits in particular the determination over a surface of the local distribution of the flow direction of flow boundary layers.
