Patent DE-4004216-A1 (DE)
Inventor: SWOBODA PETER
IPC: B60R21/235
Filed: 1990-02-12
Abstract: A fabric woven from a synthetic yarn for an airbag is described. The synthetic yarn consists of a high-tenacity polyester filament yarn having a filament linear density of less than 4 dtex and a yarn linear density in the range from 250 to 550 dtex. Unlike conventional polyamide fabrics, the fabric itself is uncoated and is preferably woven from unsized yarns. The fabric does not have to be calendered. As has been found, this fabric made of fine-filament high-tenacity polyester yarn, despite not being coated, meets the demands to be made on an airbag fabric, such as low air permeability, low fabric weight and small fabric thickness and high fabric strength.

Title: Controlling wire feed speed in arc welding process for tubes - using probe device fitted to rotating head which sends signals to wire feed rollers in relation to angular position of head around tube
Inventor: SCHMIDGRUBER GERD DIPL ING
IPC: B23K9/173
Filed: 1990-08-21
Abstract: Controlling the feeding speed of the filler wire during arc welding of tube circumferences consists of fixing a plate (12) to the rotating welding head (1) which has concentrically arranged fixed probe points (a' to h'). A freely rotatable pendulum (11) with a probe device is also fitted to the welding head but due to its own weight always remains in a vertical position. As the welding head (1) rotates around the tube to be welded (4), the plate and probe points also rotate and when the pendulum, specific probe point and control circuit (13) are aligned a signal is given to the wire feed device (14,15,16). As the probe points each pass by the alignment point the control signals are changed to alter the feeding pattern. ADVANTAGE - The method does not require any adjustment when different sized tubes are worked. Only the holding roller (5) needs to be height adjusted by moving rod (6).

Patent DE-4124271-A1 (DE)
Inventor: ZSCHAECK MICHAEL DIPL ING
IPC: B42C3/00
Filed: 1991-07-22
Abstract: The invention relates to endless forms with a transverse perforation and guide holes as part of a sprocket feed perforation and a method and apparatuses for making the same. The continuously dimensionally monitored endless forms according to the invention differ from the endless forms known to date in that the specification and the requirements associated with it regarding further processing of the endless forms in EDP printers are reliably observed over the entire production volume. Each sheet defined by the transverse perforations is therefore continuously monitored to ensure that it observes the requirements regarding the distance 1B between the holes (longitudinality), the verticality 1V of the guide holes B and the perpendicularity (alpha) and the spacing 1Q of the transverse perforation A. <IMAGE>
