Patent DE-3929156-A1 (DE)
Inventor: GRUBE ERWIN
IPC: B65G47/61
Filed: 1989-09-02
Abstract: The invention relates to a storage conveyor with a charging point and a removal point, in which a removal device (20) is arranged in front of the removal point (II). This removal device (20) is formed by a separately driven conveyor belt (21) which is arranged between the two strands (2a, 2b) of the horizontally revolving chain conveyor (2). The conveyor belt (21) is guided in such a manner that it runs from a plane situated below the chain conveyor (2) into a plane above it. The hanger hooks (1), which rest with the head region on the chain conveyor (2), are picked up at the tip by the conveyor belt (21), raised from the chain conveyor (2) and transferred to a sliding rail (15) at the removal point (II), where they slide along, again with the head region, under the effect of gravity. 
<??>By means of this arrangement of the conveyor, it is possible to remove the hangers (1) in a rectilinear manner so that a high level of dynamics is possible. When the conveyor belt (21) revolves faster than the chain conveyor (2), a singling process takes place simultaneously with the lifting off of the hangers (1).

Title: Wireless signal interrogator for relay station - achieves capacitive energy and data transmission using opposite electrode pairs forming capacitors at both stations
Inventor: WANISCH JOSEF THOMAS
IPC: G06K19/07
Filed: 1990-06-05
Abstract: For the reply station energy supply, an AC signal is capacitively transmitted from the interrogation station, the signal also being at both stations as a synchronising signal. At the reply station, the signal is locked to a data bit stream by an EXOR link for generation of an AC data transmission signal. At each data bit change (0 to 1 or 1 to 0) the data transmission signal has a phase shift of 180 deg. and is capacitively transmitted to the interrogation station. There the signal is rectified in a rectifier (24) with anolog switches instead of diodes. The switches are so controlled by the synchronising signal that, on the data transmission signal phase shift, the rectifier output polarisation is changed for the data bit stream generation. ADVANTAGE - Interogation station moved over required path without affecting transmitted data and without using h.f. technique.
