Title: A method of automatically matching the impedance of a transmitter to an antenna
Inventor: FUENFGELDER HELMUT
IPC: H03H7/40
Filed: 1986-07-02
Abstract: 1. A method for automatically matching the unknown impedance of an antenna to the known nominal impedance of a transmitter using a matching network having variable impedance and which is connected on the input side via a measuring head to the transmitter output and on the output side to the antenna, which network also has at least one input-side capacitive shunt arm with a variable capacitance, consisting for example of a plurality of capacitor elements which can be switched in parallel to one another and has an inductive series arm with a variable inductance consisting, for example, of a plurality of coil elements which can be switched in series to one another, which network in addition for setting its variable impedance by changing the capacitance of the capacitive shunt arm and/or the inductance in the inductive series arm cooperates with a micro-processor which controls, in dependence on the information transferred to it on the input side by the measuring head, in particular relating to the voltage standing wave ratio (VSWR) and the phase relation, the impedance setting of the matching network in the desired direction, characterized in that, to perform a standard tuning process (STA), the transformed antenna impedance presented to the transmitter output via the matching network (AN) assumes an inductive value in a first step by changing the inductance in the inductive series arm and, relative to the Smith diagram, reaches the "G= 1" circle, in that, in a second step, by changing the capacitance in the capacitive shunt arm the transformed antenna impedance is moved along the "G= 1" circle (G= 1) until the measuring head (MK) indicates the transition from the inductive zone to the capacitive zone and thus the tuning process is concluded in that, however, if the transformed antenna impedance indicates an excessively high voltage standing wave ratio, approximately VSWR > 3 when the "G= 1" circle is reached, an intermediate step is performed in the course of the second step when a predetermined voltage standing wave ratio, approximately VSWR= 3, is reached, in which second step the transformed impedance of the antenna is corrected, by further changing the inductance in the inductive series arm, in the direction of its displacement to the "G = 1" circle and in that for the completion of these process steps, the measuring head is designed in terms of circuitry to issue control information to the micro-processor (MP) in such a way that these items of control information have, in addition to information relating to the transmitting level (P), Phase (Ph) and voltage threshold ratios (VSWR) < 1,5 ; VSWR > 3), also a criterion for the "G = 1" circle (G = 1).

Date Oct. 24, 1996A process for manufacturing collectors, in particular flat collectors for electric machines. The individual connection elements (2) are at first directly shaped by crowding in a substantially non-machined raw conductive material (1) with their final contour and size and in their final ductile state. For that purpose, a warm forming process is used. The raw material (1) is warmed before the connection elements (2) are formed so that it does not significantly consolidate while the connection elements (2) are formed by crowding, and forming is then carried out in the warm state. In addition, a pot-shaped blank (3) may be shaped, preferably in a cold forming step, for example with inner shaped anchoring elements (6) for an insulating lining. Recesses (9) may be shaped by crowding on the cylindrical envelope (4) of the pot-shaped blank (3). These recesses are associated to the segment divisions and extend almost down to the bottom (5) of the pot-shaped blank (3). In a subsequent forming step, outer anchoring elements (13) are formed on the cylindrical envelope (4), if required a central opening (14) is cut out in the bottom (5) and the previously shaped inner anchoring elements (6) are bent outwards in the radial direction.
