  • Patent number: 9533708
    Abstract: A bearing device includes at least one kingpin, a carrier unit, a first bearing unit, and a second bearing unit. The first and second bearing units rotatably support the carrier unit relative to the kingpin. The first bearing unit includes an angular contact sliding bearing that includes a first bearing element, a second bearing element and a third bearing element, the first and second bearing elements being movable relative to each other during at least one operating process, and the third bearing element being disposed between the first bearing element and the second bearing element. During the operating process the third bearing element slides on the first and/or second bearing element, and the third bearing element is formed at least partially from a polymer.

  • Patent number: 4104057
    Abstract: A low carbon high chromium alloyed steel is made by an underpressure treatment wherein a steel melt with a high chromium and carbon content is supplied with a gaseous decarbonization agent while it is maintained at an underpressure. At the beginning of the underpressure treatment the steel flows upwardly from a ladle through an inlet into a reaction vessel and no decarbonization agent is supplied. In a second phase of the treatment a high quantity of decarbonization agent is added directly to the melt which flows upwardly from the ladle into the reaction vessel. In a third treatment phase a small quantity of decarbonization is supplied. The melt is subsequently deoxidized and alloy corrected and it is then poured off from the reaction vessel. The apparatus includes a reaction vessel which has a downwardly extending inlet connected to the ladle and an outlet spaced from the inlet extending down into the ladle within the melt thereof.
