Abstract: A radiation-emitting chip (2) with a radiation-transmissive window (5), which has a refractive index nF and has a main area (19), with a multilayer structure (9), which contains a radiation-active layer (10) and adjoins the main area (19) of the window (5), and with a radiation-transmissive medium surrounding the window (5) and having the refractive index n0, the window (5) having at least two boundary areas (6, 7), which form an angle ?, for which the relationship 90°??t<?<2?t where ?t=arc sin(n0/nF) is satisfied. A radiation-emitting component contains a chip (2) of this type.

Abstract: An arrangement with a height-adjustable component includes an approximately vertically extending upright which bears the component, the upright including a pneumatic spring. The pneumatic spring has a cylinder having a bottom end connected to a fixed part of the arrangement. A piston displaceably arranged in the cylinder subdivides the cylinder into a bottom cylinder chamber and a top cylinder chamber and has a piston rod at one end. The piston rod projects through the top cylinder chamber and is guided out of the top end of the cylinder and bears the component at its free end. The top and bottom cylinder chambers are filled with a gas filling, under positive pressure, which subjects the piston to an upwardly directed push-out force corresponding approximately to the opposing weight-induced force of the component. A valve allows a gas flow from the top into the bottom cylinder chamber and blocks the same in the opposite flow direction.

Abstract: The invention relates to a method for the provision of a device code for an electronic device, which is at least required for the first commissioning of the device code, whereby the device is inoperable without the input of the device code. The method is characterized in that the following procedural steps are carried out: Storage of a device number and an appropriate device code in a database, delivery of the device to a further processing site and readout of the device code stored in the database in conjunction with the device number, whereby the previous or simultaneous storage of a selected code number in the database in conjunction with the device number is required for readout.

Abstract: A camera includes a columnar camera main body portion having a photographing lens, and a flexible display for displaying an image of an object to be photographed through the photographing lens, in which one end of the flexible display is attached to the camera main body portion, and which is provided so as to be taken-up into the camera main body portion.

Abstract: A piston rod and a piston are installed with freedom of axial movement in a cylinder filled with a working medium, the piston dividing the working space into a space on the piston-rod side of the piston and a space on the side of the piston facing away from the piston rod. A stop disk is mounted on the piston rod in addition to the piston rests against a retainer provided on the cylinder to limit the outward movement of the piston rod during a fire.

Abstract: The present invention provides a method of testing a cryogenic metal tank before it is put into service, in which said method said tank (1) is filled with water and appropriate measurements are performed where necessary, the method being characterized in that the following steps are performed: filling said metal cryogenic tank (1) with sea water; and providing the bottom and side metal walls (2, 3) of said tank (1) that are constituted essentially by bare steel, with temporary cathodic protection by injecting an electric current into anodes disposed within said tank (1) once said anodes become immersed. Advantageously, a first anode array (51) is placed in the immediate vicinity of the bottom of the tank using support means (52), said support means (52) and said first anode(s) (51) preferably being removable.

Abstract: A compacting press having a support section, a compacting section which undergoes translational movement along a vertical axis (Z, Z?) which is fitted with a thrust-plate and which forms a ram designed to compress cases by the application of pressure, and a guide assembly made up of a skirt, with a liner, a hoop and a cradle. The cradle is fitted to a skirt holding section by a removable connection made up of a reversible assembly system involving the fitting into place and horizontal movement of at least one key-hole shaped opening which passes vertically through the cradle and at least one vertically orientated mushroom-shaped lug. This press is preferably used for compacting a case containing hazardous materials, in particular radioactive waste.

Abstract: A mounting arrangement for glass doors includes an upper mounting having a mounting body with a clamping device for the glass leaf and a displaceable bearing pin for engaging in a counterbearing at a transom and a lower mounting with a mounting body with a clamping device for the glass leaf, and with a receiving recess for a floor door closer or a floor bearing. The two mounting bodies are arranged parallel to the vertical axis (H) of the glass leaf, and each clamping device is provided with longitudinally extending grooves for receiving fastening screws which project through screw holes in the clamping device and bore holes in the glass leaf. A clamping insert is provided for inserting into the grooves and has a recess for a cover panel. The mounting body and the counterbearing can be covered by means of covers, wherein the cover is provided with elongated holes which extend under the clamping insert and cover panel.
