Abstract: A method for producing a tubular-shaped wire mesh which serves as cladding for catalytically coated cylindrical one-piece ceramics units used to decontaminate exhausts of internal combustion engines. These units function as catalysts and have a wire mesh wrapped along a circumference and around the surface of an arbor of the unit. The wrapping is such that the mesh is axially longer than the distance between two end faces of the units. The mesh has a section projecting axially beyond each end face of the unit. The wire mesh is secured to the surface of the arbor in an area which is directly adjacent to the projecting section. The projecting section is compressed into a bead to a predetermined axial extent.

Abstract: An operating table includes a support surface with several support surface sections hydraulically adjustable relative to one another, a support column for the support surface with a column head (16) on which head the support surface is supported for pivotal movement and hydraulic adjustment and with a column foot (14) which is connected with the column head (16) through a hydraulic lifting apparatus (18), and a hydraulic unit (24) for operating the lifting apparatus and the work cylinders for adjusting the support surface sections. The hydraulic unit (24) is arranged on the column head (16). The lifting apparatus (18) includes two antiparallel lifting cylinders (26, 28) arranged next to one another and connected in parallel with one another having similar interior cross sections, the piston rod (30) of one cylinder being connected with the column head (16) and the piston rod (32) of the other cylinder being connected with the column foot (14).
