Title: Assembling heat exchange tubes for water heaters - using solder rods positioned by inserting tubes into fin assemblies
Inventor: SCHMIDT ERNST DIPL ING
IPC: B23P15/26
Filed: 1973-01-19
Abstract: The solder rod is loosely held in the assembly of fin lamellae by hooking one of its ends over an end lamella. The rod length is not > the width of the combustion chamber opening of the heater into which the assembly is fitted.

Title: Servocylinder for automatic processor control - motor gives reference position for piston rod of working cylinder
Inventor: KRAEMER MANFRED DIPL-ING
IPC: F15B9/12
Filed: 1973-06-29
Abstract: Rotary motion of the motor is converted into a translational motion of the control piston of the path valve, which is in the lower part of the cylinder housing, and which controls the supply of pressure medium to the working cylinder.
