  • Patent number: 8087395
    Abstract: A multi-part piston for an internal combustion engine has an upper piston part and a lower piston part. The upper piston part and the lower piston part each have an inner and an outer support element, which elements delimit an outer circumferential cooling channel and an inner cooling chamber, whose cooling chamber bottom has an opening. The opening is closed off with a separate closure element, which has at least one cooling oil opening.

  • Patent number: 5632381
    Abstract: An apparatus for sorting paper materials includes a separating mechanism for thinning the paper materials and a sensing mechanism for classifying the paper material according to type. The separating mechanism includes a plurality conveyor belts operating at successively higher speeds, whereby passing materials from one conveyor belt to another conveyor belt results in spreading the paper material. The sensing mechanism includes a mechanical striking device to strike the paper material, a microphone to detect the sound caused by the striking device and an evaluation unit to determine the type of paper material on the basis of the sound.
