In order to obtain a long working life as well as reliability and a high performance, the tractive-power motor (16) or both motors are asynchronous and there are provided devices (30) for sensing the angular positions a...

Sheet delivery of a printing machine having a gripper system running on an endless conveyor includes air containers located adjacent the endless conveyor and being formed with a sheet-wide field of air-outlet openings, the gripper system including grippers for gripping a sheet of printing material at a leading edge thereof so that the sheet is floatingly conveyable by the endless conveyor over the...

A method of improving wear-resistance characteristics of a porous metal machine part by densifying the part throughout its thickness. The method includes the steps of ultrasonically cleaning the part to remove impurities from the pores of the part and then drying the part. The part is then exposed to cryogenic temperatures generated by a cryogenic liquid during a period of time. The period of time...

In the formation of a tread pattern having many sipes (30), a combination of pitch segments (15, 16, 17) having a plurality of kinds of pitch lengths (L1,L2,L3) is selected so as to substantially match with the tread circumference (T) and an inner peripheral length (L) of a sector member (36) constituting part of a split mold (35) in order to prevent intersect of the sipes with any dividing positi...

A method and apparatus for securing enlongate members (24, 28) of generally cylindrical form in end-to-end relationship, particularily for forming an optic fiber splice (30). Optic fibers are spliced by pressing a form, preferably an optic fiber of the same diameter as those to be spliced, into a deformable body (8) to create a groove for receiving the ends of the optic fibers in close alignment. ...

Additive contains 50 to 70 per cent weight of perborate sodium and 15 to 48 percent weight of sodium diphosphate 1 to 15 per cent of twosodium salt of dinaphthylmethanedisulfonic acid, 1 to 20 per cent weight of glycodes or its epimers. This additive in lead accumulators substantially lowers the contents of irreversibile plumbous sulfate and lowers the possibility of its future creating.
