Title: Process and apparatus for bending a thin-walled workpiece
Inventor: KOLB RUDI
IPC: B21D11/20
Filed: 1993-10-19
Abstract: A workpiece (48) is inserted into an insertion gap between a stationary bending core (46) and a bending tool (22). The bending tool (22) is fastened on a rocker (24) which is driven, such that it can be moved up and down, with a press ram. Formed on the press ram is a curved track (20) into which a bolt (26) of the rocker (24) engages. On the opposite side, the rocker (24) exhibits a bolt (28) upon which a downwardly acting tensile force acts. During the bending operation, the rocker (24) is displaced by way of the curved track (20) such that a bending surface of the bending tool (22) carries out a rolling movement on the workpiece (48). The curved track (20) is an involute to the outer surface of the workpiece (48) bent over the core (46). <IMAGE>

Title: Electric door opening system mains device
Inventor: BOESER WERNER
IPC: E05F15/603
Filed: 1993-11-27
Abstract: The mains device is provided for an electric door opening system. The system uses a constant voltage of a predetermined, relatively small amplitude and also an alternating voltage of a predetermined, relatively small amplitude to supply different modules, such as bell buttons, a door opener, an audio signal generator and intercom units. The device has transformer connected at its primary side to the mains ac voltage. An output ac voltage line is connected to the secondary side of the transformer, with a phase line (1) and an ac voltage null line (2). A bridge rectifier (4) is connected at the secondary side of the transformer. A constant voltage regulating circuit (8) is connected to the output terminals (5,6) of the rectifier (4) and to a constant voltage neutral line (7). The regulating circuit (8) has an output line (9) for the controlled voltage. Only one neutral lead connection (10) is provided for both the ac and dc neutral lines (2,7). The transformer only has one secondary terminal (11) to which the phase line (1) and the ac neutral line (2) and the rectifier inputs (3) are connected. A neutral line switch over contact (12) is provided between the dc neutral line (7) and the ac neutral line (2). A single output terminal (13) is provided to output ac voltage and dc voltage. A phase line switch over contact (14) is provided between the output terminal (13) and the phase line (1) and dc output line (9). The two switch over contacts (12,14) normally close the dc circuit. When an ac load is connected to the neutral line connection (10) and the output terminal (13) causing current flow in the regulating circuit (8), the switch over contacts (12,14) change and close the ac circuit. When the ac load is removed the contacts (12,14) switch back to the dc circuit.

Inventor: WANDKE ERNST DR ING
IPC: B23K1/08
Filed: 1994-06-23
Abstract: The invention concerns a method of soldering circuit boards and similar articles, the method calling for the circuit boards or other articles to be passed through a basically enclosed, tunnel-like installation in which they are heated, soldered and cooled at least sufficiently for the solder to solidify. The invention is characterized in that the soldering technique used is determined in advance for one or, preferably, several circuit boards, the principal techniques used being wave, reflow and, in particular, combined wave/reflow soldering or a special soldering technique. Depending on the soldering technique selected, the heating and conveyor elements in particular are also adjusted to heat and convey the circuit boards in a suitable way through the installation, and the associated soldering bath brought to the appropriate operating conditions. Following suitable adjustment of at least these parameters, each of the circuit boards can be processed.

Filed: 1994-11-09
Abstract: The thermal treatment process involves combustion or other processes within a melting cyclone above a lower furnace at temps. above 1300 deg. C. By setting a specific partial pressure of oxygen in the melting cyclone and by using at least one blast lance in the furnace, the evaporation of any heavy metal which may be present is reduced. Thus, the residual slag has an extremely low heavy metal content. The added material used is selected so that the residual slag, after cooling, can be used as a component of granulated sand from which blast furnace cement can be produced.
