Patent DE-3221831-A1 (DE)
Title: Thyristor arrangement
Inventor: MATSUURA TOSHIAKI
IPC: H02M1/092
Filed: 1982-06-09
Abstract: A thyristor arrangement is created having thyristor branches (10) forming a three-phase bridge. Each of the thyristor branches (10) has a series circuit of thyristors (11) to each of which a gate signal is applied which is generated by a circuit (25) which produces a signal that switches the gate into the operating position, a circuit (17) which produces the gate light signal, and a circuit (19) which produces an electrical gate signal. A branch overvoltage suppressor (12) is connected in parallel with each of the thyristor branches (10) so that the branch overvoltage suppressor (12) is discharged by a voltage surge which is supplied to the thyristor branch (10). The discharge is detected by a voltage dividing resistor (16) and a discharge detection light signal generating circuit (20), and a discharge detection light signal (S4) is supplied to a discharge detection light signal receiver circuit (22). The discharge detection light signal receiver circuit (22) responds to the discharge detection light signal (S4) and causes an invertor (23) and an AND gate (24) to block the gate signal described above. Accordingly, in such a situation, the thyristors (11) are not switched into the operating position, and an excessive switching loss is thus prevented. <IMAGE>

Title: Method of sealing off container parts provided with a threaded attachment flange
Inventor: BIRKLE SIEGFRIED DIPL CHEM DR
IPC: B65D90/08
Filed: 1982-07-26
Abstract: A container composed of a plurality of parts, wherein the individual container parts are held together releasably by screws, can only be made tight with great difficulty. This problem occurs, in particular, in the case of containers for aluminising, where, for example, a closure hood must be connected absolutely tightly to the galvanising trough. According to the invention, this problem is solved in a simple manner in that sealing lamellae (7, 8) are welded onto the opposite surfaces of the flanges (2, 4) to be joined together and, after the sealing lamellae (7, 8) lying one above the other have been joined together, are butt-welded to one another at the ends (13). <IMAGE>
