Abstract: A device is provided for assembling article groups from layers of rod-shaped articles used in the tobacco-processing industry. The rod-shaped articles are stacked one above the other and side-by-side in group forming bins that are intermittently movable in a forward direction. A number of funnels are provided that correspond, respectively, to the number of the article layers. Each funnel is divided into chutes. The chutes of each funnel receive the rod-shaped articles at chute inlets and are arranged for dropping the rod-shaped articles to chute outlets to form a layer of parallel aligned rod-shaped articles. A platform is disposed at each chute outlet for receiving the respective layer of parallel aligned rod-shaped articles. The platforms are staggered at successively different heights to define respective layer planes.

Abstract: The invention relates to a method for calibrating an oscillating receiver circuit of a transponder in an RFID system to resonance to the frequency of an inquiry signal transmitted by a reader, the oscillating receiver circuit comprising at least one inductive resistor and at least one capacitor. Immediately after the start of reception of the inquiry signal, capacitors are connected in increments to the capacitance of the oscillating receiver circuit until such time as the rectified, smoothed inquiry signal assumes a maximum voltage value. This active self-calibration is performed upon each initialization of the transponder but can also be addressed by having the reader send a special sequence to the transponder.

Abstract: A method for manufacturing a light emitting diode with the following process steps. Preparation of a substrate; production on the substrate of a series of layers which include the pn junction, that generates the radiation; production of contact layers on the surface of the layers including the pn junction and generating the radiation, and on the rear side of the substrate; and tempering of the contact layers. The method is characterized by the surface of the layers including the pn junction and generating the radiation being frosted or roughened before the contact layers are deposited. Through frosting the front side, it is possible to increase the luminous efficiency of the diodes by about 25%. Since the frost-etching process is performed before the contact layers are produced, this method can be used when aluminum is to be used as the contact material.
