Title: Sheet-fed printing press and process for printing of a multicolor print image
Inventor: SIMETH CLAUS
IPC: B41F11/00
Filed: 1997-07-23
Abstract: The present invention relates to a sheet-fed printing machine having a sheet-feeding unit and a control device assigned thereto for sheet feeding and operating synchronously with the machine cycle. When collecting printing images  on a rubber roller (21, 26) or on a gripped printing sheet, said sheet-feeding unit feeds a printing sheet or waste sheet, only. The sheet-fed printing machine further has sheet-guiding printing cylinders (5, 22) or drums (4, 6, 7, 8, 13, and 14) for transportation of at least one printing sheet. At the same time, the printing sheet is gripped by means of the printing cylinder (5, 22), optionally the sheet-guiding drum  (6) for printing with one or several colors and for at least one passage through a printing zone. Printing process is characterized in that two partial images of a two-color printing image are transferred from a plate cylinder (10) to a rubber cylinder (21, 26) so that the two-colored printing images are collected overlapping each other on the rubber cylinder (21, 26) for printing on the gripped printing sheet. Printing images are then transferred together onto printing sheet to be printed. At the beginning of printing, first both the partial images are applied to the rubber cylinder (21, 26), whereupon both the partial images are applied in position-correct overprint to the first printing sheet. The subsequent and next printing sheets are synchronously fed only when a complete new printing image on the rubber cylinder (21, 26) is prepared.

Title: Micro-carriers with fibronectin suitable for cultivation of animal cells, process for preparing and use thereof
Inventor: STOL MIROSLAV ING
IPC: C12M3/00
Filed: 1989-11-13
Abstract: The solution involves biologically active spheric gels from aldimine derivatives of gelatine on the surface of which fibronectin is adsorbed biospecifically. These microcarriers are suitable as a cultivation bed for cultivating animal cells. Microcarriers are formed by 50 to 350 μm spherical particles from the aqueous gel of aldimine derivatives of gelatine, which are reaction products of gelatine and a-amino acids with dysfunctional aldehydes, on the surface of which adhesive protein - fibronectin is adsorbed biospecifically. Microcarriers are prepared by putting spherical micro particles from a water gel of aldimine derivatives of gelatine into contact with a water solution containing fibronectin at pH 5 to 8 for 1 minute to 24 hours. Ballast components of the fibronectin solution are then washed away with a water buffer with the same pH and the product is preserved by freezing or lyophilization or by transferring it to a 20% to 99% solution of a suitable water-mixing organic solvent. After defrosting or swelling in water or after washing away the solvent and transferring to an aqueous physiological buffer with a pH 7 of 7.6 the product is used as a cultivation bed for cultivating animal cells under standard cultivation conditions.
