Abstract: A method of forming a partially perforated assembly comprising a perforated facestock material, an unperforated liner, and a self-adhesive adhering the perforated facestock material to the unperforated liner, the method comprising forming a temporary assembly including the perforated facestock material, the self-adhesive, and a temporary carrier adhered to the perforated facestock material by the self-adhesive, the perforated facestock material having been perforated by material removal of portions of the facestock material, removing the temporary carrier from its adhered relation to the perforated facestock material, and after the removing, adhering the unperforated liner to the perforated facestock material by the self-adhesive to form the partially perforated assembly.

Abstract: A method for producing a hollow camshaft comprising i) forming a camshaft preform by providing a hollow metal pipe, expanding the hollow pipe at spaced longitudinal locations by applying pressurized fluid internally to the hollow pipe, axially compressing the hollow pipe during the expanding step to accumulate metal at the spaced longitudinal locations, the expanding and compressing steps forming a camshaft preform having cam preforms of associated predetermined widths in a longitudinal pipe direction; and ii) forming a final camshaft from the camshaft preform by axially compressing the camshaft preform while applying the pressurized fluid to reduce the predetermined widths of the cam preforms while shaping the camshaft preforms into the final camshaft, the final camshaft having cams of relatively smaller widths in the longitudinal direction than the predetermined widths of the cam preforms.

Abstract: The invention relates to a method for the selective hydrogenation of a dinitrile compound in the presence of a catalyst which comprises a metal of group 8 of the periodic system of the elements, the catalyst comprising a zeolite having a pore diameter of between 0.3 and 0.7 nm. The zeolite preferably has a structure chosen from the structures: ABW, AEI, AFT, ANA, ATN, ATV, ATT, AWW, BIK, CAS, CHA, DDR, EAB, EDI, ERI, GIS, JBW, KFI, LEV, LTA, MER, NAT, PHI, RHO, THO, YUG.
