Patent WO-02092271-A1 (WO)
Inventor: MADSAK JUERGEN
IPC: B23K9/20
Filed: 2002-05-15
Abstract: The invention relates to a method for monitoring a welding process during the welding of studs, wherein a part to be welded (19) is immersed in a melt by moving a controllable part (5) of a stud welding head (3) in the direction of a workpiece (17). A physical variable dependent on the force to be expended for the movement of said part (5) is measured at least during the time period corresponding to the immersion phase of the workpiece (17) and the measured phyiscal variable/time value is compared with a predetermined setpoint value. The invention also relates to a stud welding device for carrying out said method.

Title: Rolling teeth on conical gears
Inventor: V JAKIMANSKIJ VASILIJ
IPC: B21H5/04
Filed: 1968-12-03
Abstract: The rolling tool is fixed to a spindle performing a translatory movement and arranged at an acute angle with regard to the spindle carrying the workpiece. The synchronised rotation of the spindles is ensured by a pair of conical rolls whose toothed wheels are keyed onto the spindles, and which are put out of gear when the workpiece is being installed or removed. One spindle performs an inclined movement around a joint whose axis is perpendicular to the plane passing through the spindle axis. The movement occurs when the conical synchronisation wheels are disengaged. The latter are changed when the dimensions and shape of the workpiece change.

Title: Filling large ethylene oxide tanks under inert gas pressure - in safe, economical manner while maintaining closed system
Inventor: MICHEL OTTO DIPL ING
IPC: F17C9/00
Filed: 1974-01-18
Abstract: One or more ethylene oxide (EO) tanks of over 1 m3 capacity, which are under inert gas pressure, are filled with EO from a tank car, while maintaining a closed system, by releasing and recycling an EO-inert gas mixt. before or after extn. of liq. EO. EO is a hazardous material which must be kept under inert gas pressure and as far as possible not released into the atmosphere. Process eliminates expense of lifting condensers to EO tanks, and also loss of inert gas and thereby partial escape of EO, otherwise caused by releasing inert gas after pressurising EO tank. Regardless of internal pressure in EO tank, a constant quantity 3-150 m3/hour, of EO-inert gas mixt. is withdrawn by releasing pressure in tank. This mixt. is again compressed to 2 to 10 atmos. gauge and is condensed at -20 degrees to 10 degrees C, and the inert gas, still contg. some EO vapour, is passed to a pipeline connected to a gas holder used as intermediate storage. Condensate is let down to 1.2 to 10 atmos. gauge and distilled at 30 degrees to 100 degrees C, giving pure EO, which is condensed and passed to stock tank. Inert gas mixt. from gasholder is fed to suction side of compressor, which forces mixt. into pipeline and gasholder as required by consumption of EO. It is advantageous to use isothermally operating compressor employing glycol as liq. seal.
