Title: Radio communication system
Inventor: HEIDEMANN ROLF
IPC: H04W92/00
Filed: 1991-06-14
Granted: 1998-10-06
Abstract: In a cellular mobile-radio system with radio stations and transmission facilities remote therefrom, the radio stations send out radio signals and receive radio signals which, in each case, contain information signals. According to the invention, as many as possible of the processing functions are shifted from the radio stations to the transmission facilities. The radio signal to be sent out by the radio station is easily generated in the radio station because in the transmission facility, an unmodulated carrier and a carrier modulated with the information signal is produced, in which case the carriers differ in frequency by the amount of the carrier frequency of the radio signal. These two optical carriers are transmitted to the radio station and are mixed there in an optical receiver, so that the radio signal containing the information signal is generated. A radio signal that is received in a radio station is transmitted optically to a the transmission facility and is processed further there. This transmission is carried out by the fact that an optical transmitter present in the transmission facility generates an unmodulated optical carrier and transmits it to an optical modulator located in the radio station. In the optical modulator, the light, modulated with the received radio signals, is sent back and the radio signal is recovered by optical heterodyne reception of the unmodulated and modulated carrier.

Title: Mechanism for adjusting the gap between the stripper plates of a harvester
Inventor: CARON NORM
IPC: A01D45/02
Filed: 1991-10-11
Granted: 1995-03-21
Abstract: A mechanism for adjusting the stalk-receiving gaps between  stripper  plates  in  a  produce  harvester.    The mechanism is adpated for use in harvester where a number of pairs of stripper plates are utilized, and where a space is formed between adjacent pairs of stripper plates,  and a stalk-receiving gap is formed between the stripper plates within each pair.  The mechanism permits all stalk-receiving gaps in the harvester to be adjusted simultaneously and to the same degree.  These gaps are adjusted from both sides allowing for optimum centering of the gap to engage the stalks.    The mechanism comprises  a  reciprocating  shaft disposed so as to move substantially perpendicular to the movement of the harvester.  A number of rotating shafts are connected to the reciprocating shaft and these are disposed within the spaces between adjacent pairs of stripper plates.          The rotating shafts are disposed substantially at right angles to the movement of the harvester.  Each rotating shaft is connected to the stripper plates on either side of the space between the adjacent pairs of plates by linkage arms.          As the reciprocating shaft is moved, the rotating shafts rotate or roll, causing the stripper plates on either side of the spaces between adjacent pairs to move towards or away from each other, depending on the direction of movement of the reciprocating shaft.   This movement causes the stalk-receiving gaps to be increased or decreased in size.
