Title: Resistance welding coated sheeting
Inventor: ALFRED BECKER DR OTTO
IPC: B23K11/16
Filed: 1969-05-31
Abstract: Welding current is fed, at least for one of the coated sheets, indirectly to the point to be welded by means of the sheet surface in order that an external layer remains intact and a contact established between the surfaces which have been uncovered for welding.

Title: Load dependent air bellows suspension - has quick action bypass regulator valve and common axle levelling valve
Inventor: VOGEL FRIEDRICH-OTTO
IPC: B60G17/052
Filed: 1973-07-20
Abstract: The regulator valve and the bypass valve comprise a single unit fitted to the vehicle super-structure between the suspension air tank and the air bellows main feed pipe.

The regulator valve allows air to pass from the tank to the bellows until a preset distance between chassis and axle is reached is determined by a regulator bar between axle and valve. Should the preset distance be exceeded, the bypass which has a larger flow cross section, is opened to permit a rapid filling or emptying of hte bellows.
