Abstract: In an electroluminescent panel comprising a transparent electrode, a back electrode, and an electroluminescent layer between the transparent and the back electrodes, an intermediate layer is interposed between the electroluminescent layer and the back electrode and essentially consists of germanium and nitrogen. The intermediate layer serves as a light absorption layer for absorbing ambient light. A nitrogen distribution in the intermediate layer may be either substantially uniform or decreased from the electroluminescent layer side towards the back electrode side. The decrease may be made stepwise or continuously. The intermediate layer may be superposed through a dielectric layer or directly on the electroluminescent layer.

Abstract: A structural arrangement is provided which is particularly useful in connection with solar greenhouses. The structural member is suitable for use in a parallel arrangement of the same particularly for the purpose of providing controlled shading. The structural member is provided as a hollow bar of elongated form provided with at least one longitudinally extending track channel having a relatively narrow longitudinally extended slot-mouth. The bar may be provided with two such channels and these channels are substantially circular in cross-section with the mouths defining reentrant angles therewith. In a solar greenhouse, members of the above type support a glazing with a curved-eave section, the bars being curved to shape and the channels therein accommodating the bulbous lateral edges of shades which are retained therein. The shades are transferred from one roller in the direction of a second roller.

Abstract: In a laser plasma X-ray device for use in generating X-rays by bombarding a target material by a pulsed laser beam, the target material is selected from materials which are in a gas phase at the room temperature and which are cooled in a selected one of liquid and solid phases. Such a selected phase of the target material is continuously supplied to a focal point of the pulsed laser beam to be subjected to bombardment and to generate the X-rays. On generation of the X-rays, the target material is rendered into the gas phase to be recycled into the selected phase. The X-rays are guided outside of the chamber through an X-ray gate unit opened in synchronism with a repetition frequency of the pulsed laser beam.

Abstract: A discharge coating apparatus comprises an assembly for applying a vibrational motion in the longitudinal direction of an electrode while applying a voltage pulse in synchronization with the vibration to cause electrical discharge between the surface of a workpiece and the electrode and the formation of a coating layer on the workpiece of the material of the electrode due to the heat produced by the electrical discharge. An additional motion is applied to the electrode to cause the electrode to undergo reciprocal travel towards and away from the suirface of the workpiece at an angle relative thereto. The additional motion can be a rotational motion. The electrode can be formed with a concave portion at its tip or with an axial bore so that only an annulus of the electrode contacts the workpiece. The additional motion can be a skipping movement by utilizing a skipping mechanism consisting of an elastic memebr.

The nonwovens and the foam block are bonded together at their periphery by thermal-welding. The pad can be coated with abrasive fillers. It can also be used for scouring delicate surfaces when it contains little or no abrasive fillers.

Abstract: A body (1) of oriented thermoplastic material is converted through heating in an area adjoining one boundary surface of the material portion to a layer (10) of substantially non-oriented material. A film (2) is fixed to the fixing layer (10) by pressing the film with a compression and heating element (50) and the necessary heat is supplied so that the film (2) will be fixed to the fixing layer (10). Since the film is bonded to substantially non-oriented plastic material, the desired detachability in the bond between the film and the material portion (1) is achieved.

Abstract: A cooling device for plastic granulate which is formed by cutting plastic strands emerging from a nozzle plate of an extruder and is fed to a stream of cooling water which adjoins the nozzle plate in the region of a cutting device. A pipe conducts the stream of cooling water containing the granulate to a granulate-water separator. In order to obtain a well-defined, infinitely adjustable dwell time of the granulate in the stream of cooling water, the pipe is essentially developed as a vertically arranged riser having a larger cross section passage area than that of the pipe itself. The upper outlet end of the riser is connected to the suction side of a feed pump, which serves as a section pump, and to a suction pipe which has an end connected to ambient atmosphere. A regulating valve is connected in the suction pipe. The delivery side of the feed pump communicates with the granulate-water separator.

The control unit includes a number pair generator (5) for generating an identification number parallel with the address number, which number pair is assigned to the same function unit. The identification number is transferred via the information bus (6) and is registered during system starting in a registering means (11, 12) included in said function unit.
