Abstract: The present invention relates to a door (10) for a cold storage device such as a refrigerator or freezer. The door comprises a frame (12) and a pane (14) fitted to the frame. The door is characterized by at least one light emitting diode (LED) (16) arranged such that heat generated by the LED(s) during operation of the LED(s) is conducted to the pane to reduce moisture-forming on the pane. The present invention also relates to a cold storage device (24), such as a refrigerator or freezer, comprising such a door.

Abstract: A method and an apparatus are described for regulating the concentration of metal ions in an electrolytic fluid, which is used for the deposition of metal with insoluble anodes and additionally contains compounds of an electrochemically reversible redox system. With the oxidized form of said system, metal is dissolved in an ion generator 1, traversed by the fluid, so that these compounds are thereby reduced. For the deposition of metal, the dissolved metal ions on the item to be treated are reduced. The compounds of the redox system in the reduced form are oxidized again on the insoluble anodes in the electroplating system 13. In order to keep the concentration of the metal ions in the electrolytic fluid constant, at least a portion of the electrolytic fluid, contained in the electroplating system, is conducted through one or a plurality of electrolytic auxiliary cells 6.

Abstract: Superconducting, oxidic ceramic materials are worked to filamentary conductors, in that they are filled into silver tubes (2), drawn with the latter to filamentary conductors and then sintered under flowing oxygen. So that such filamentary conductors can be produced industrially with an adequate quality, drawing speed and yield, the silver tube (2) as a sintered sleeve is brought into contact with the ceramic material (1) in a drawing sleeve (3), of soft annealed steel (35) and the resulting sleeve combination undergoes the drawing stages. After drawing the steel drawing sleeve is removed by etching. In a large number of drawing stages, it is necessary to remove the drawing sleeve which has become hard due to the cold working and to replace it by a new, soft annealed sleeve. Simultaneously the sintering sleeve can undergo soft annealing.

Abstract: The apparatus for electrolytically treating printed circuit boards 3, through which apparatus the printed circuit boards are continuously guidable in a plane of conveyance in a substantially horizontal direction of conveyance, has the following features: Counter-electrodes 1,2 are disposed opposite the plane of conveyance and substantially parallel thereto on at least one side, so that electrolytic chambers 4,5 are formed between counter-electrodes, which are situated opposite one another, or between the counter-electrodes and the plane of conveyance, the counter-electrodes forming respective substantially continuous electrode faces. Guide elements 7,8 for the printed circuit boards are disposed in the electrolytic chamber. Contact elements 11 are provided for the electrical contacting of the printed circuit boards. Electrolyte spraying arrangements 13 are also provided for conveying the electrolytic fluid towards the surfaces of the printed circuit boards. Openings are provided in the counter-electrodes.

Abstract: The apparatus according to the invention is used for electrolytically treating a board-shaped substrate to be treated, preferably printed circuit boards, in a continuous system, through which the item to be treated is guidable in a plane of conveyance in a substantially horizontal direction of conveyance, the apparatus having counter-electrodes (2), which are situated substantially parallel to one another opposite the plane of conveyance, and screens (11) for shielding from high current density fields in the edge region of the item to be treated (1), said screens being disposed between the plane of conveyance and the counter-electrodes, the screens each being in the form of at least two flat portions (12,13), which are disposed substantially parallel to each other, one portion (13) of the screens being disposed so as to lie opposite the plane of conveyance, and the other portion (12) being disposed so as to lie opposite the counter-electrodes, and the screens being mounted so as to be displaceable in a direct

Abstract: The disclosed gun is of the type having a housing with a nozzle and a deflecting plate spaced from the muzzle and mounted on a rod axially guided in the muzzle, the annular channel formed between the muzzle and the rod serving as a powder channel. Electrodes extend into the powder channel and are connected to a high voltage source. A stepping motor is connected to the rod to change its axial position, and control means are connected to the motor. Digital circuits inside the housing and manually operable switches permit automatic control or manual control from the gun of the deflecting plate spacing, the voltage, and the powder feed. Indicating means on the gun display the values of the controlled parameters.
