Title: Gathering of tubular skins, esp. sausage skins - by forming inflated tube into caterpillar using rotating tool and opposing force by tangential gas jets
Inventor: WOLF HANS
IPC: A22C13/02
Filed: 1990-05-30
Abstract: The invention relates to a process and appts. for gathering in tubular covers, particularly synthetic sausage skins. The inflated skin is conveyed to a gathering tool which rotates around the central axis of the skin and applies a force to the outer surface. Folds are formed in the skin and with an opposing force are pressed together to create a caterpillar form. A tangential force is applied by a gas to the outer skin surface just in front of the gathering tool and opposes the radial force created by the rotating gathering tool on the outer skin surface. Appts. comprises a gathering tool for applying a rotating force on the skin and nozzles arranged around the tubular skin to apply tangential force.

Title: Etching of structures in wafers or single crystalline material - using masking layers in which structures are etched at different depths corresp. with depth required in silicon@ substrate
Inventor: LAERMER FRANZ DR
IPC: H01L21/308
Filed: 1991-09-03
Abstract: Wafers (1) of single crystalline material pref. Si, are structured by the formation of trenches of varying depths by using different durations of exposure to an etchant through a window in an etch resistant surface layer. The feature is that on the surface of the wafer patterns of different depths are formed in the etch resistant surface layer (SiO2 + Si3N4). Before an etch step, the required windows are made to extend to the surface of the Si wafer. The depth of pattern etched in the etch resistant layer pref. correlates with the depth in the Si wafer required. The order in which the patterns are etched in the Si surface is pref. that of reducing depth of the patterns etched into the masking layer. The wafers may be etched on both surfaces. The masking layer is pref. masked using a positive photoresist layer and etched using an ion plasma process. USE/ADVANTAGE - Allows the formation of structures in single crystalline wafers without the disadvantages of low selectivity of the masking layer. This avoids pattern degradation by the formation of birds beaks and long oxidn. times and the requirement to re-oxidise between etching of different structures. The process lends itself to batch operation using a high deg. of automation.
