Abstract: The disclosure relates to a device for forming container groups with a predetermined container piece count from a continuous container stream in a transport area of a filling plant, comprising an infeed conveyor belt, an outfeed conveyor belt, a conveyor belt interposed between the infeed conveyor belt and the outfeed conveyor belt, and a drive station for introducing separating elements and forming container groups. Here, the speed of a separating element introduced into the region of the transport belt is controlled to no more than the first speed, in particular to a speed lower by no more than 2% than the first speed, as long as the following container group has not been fully moved onto the transport belt. The disclosure further relates to a method for forming container groups.

Abstract: A process for treating bovine pericard tissue to increase resistance to biological degradation by wet-chemical processing, The wet-chemical processing consists essentially of: (i) separating any adherent fat and basal membrane from the tissue; (ii) contacting the tissue with an aqueous, alkaline solution of sodium hydroxide, potassium hydroxide, lithium hydroxide or sodium carbonate to swell the tissue; (iii) contacting the swollen tissue with an aqueous sodium chloride solution to control the swelling; (iv) contacting the tissue with a solution of a metal-ion complexing agent with a pH in excess of 11; and (v) contacting the tissue with an aqueous buffer solution having a pH of 4.5 to 6.0. Each of steps (ii)-(v) is followed by a water rinse. The pericard tissue is then dried and sterilized.

Abstract: A positioning device with two coordinates, for the moving of two components relative to each other. The positioning device with two coordinates serves for the exact positioning of a tool or workpiece, preferably of semi-conductor discs, for the purpose of checking or fabricating in the course of the manufacturing process.
