Patent DE-1804836-A1 (DE)
Title: Spot-welding soft metals
Inventor: REITGASSL ERICH
IPC: B23K11/31
Filed: 1968-10-24
Abstract: The pressure exerted by the upper and lower electrode on the components to be welded is derived from a pneumatic cylinder. The lower electrode is fixed and the upper electrode is attached to the piston rod of the pneumatic cylinder piston. The compressed air enters the cylinder upper half for moving the upper electrode downwards through an air valve and a three way solenoid valve. The lower chamber is under a lower pressure. This chamber is similarly connected to compressed air source via a three way solenoid valve and an admission valve. The upper electrode gradually applies the pressure on the components and welding is carried out so that the bugle is not collapsed.

Patent DE-2044333-A1 (DE)
Title: Application of fluids to running threads - in an enclosed chamber
IPC: D06B1/02
Filed: 1970-09-08
Abstract: An enclosed chamber for the application of a fluid to running yarns consists of a fixed section into which a movable section interlocks. Cross slits in the two sections permit easy threading of a running yarn by a simple movement to the right of the movable section, which is mounted on a bar and spring-loaded. When the two sections return to the interlocked position, the two slits form an opening which permits the passage of the running yarn. Compressed air jets and fluid jets apply the fluid to the yarn by spraying. A filter between an air extractor outlet and the treatment zone permits a vacuum to be maintained inside the chamber, thus preventing contamination of the atmosphere and machine parts.
