    摘要： Apparatus for processing paper wherein a pair of endless curved wire devices operate to pass therebetween a sheet material to be treated for a dewatering operation or the like. A support structure in the form of individual support segments made from sintered oxide ceramics are arranged to extend over the width of the apparatus and are in contact with one another, with a plurality of the segments being arranged consecutively in the direction of the course of the wire devices, the segments having a maximum linear expanse of 700 mm per segment and having junction areas between consecutively arranged segments defining a gap for feeding cooling water to the guide wire devices.

    摘要： A piston arrangement with a metal shaft, a piston head that is attached to it with a shrink ring, and a member made of partially stabilized zirconium ozide. The top which demarcates the combustion chamber, of the piston head, consists entirely of the member made of partially stabilized zirconium oxide. The bottom of the zirconium-oxide member is a truncated cone and the top of the shaft is a truncated cone. They are surrounded by an annular component that is split into two sections parallel to the longitudinal axis of the piston. The annular ocmponent is secured with an outside shrink ring.

    摘要： A tubularly formed valve guide (1) with a bore for a metal valve shank (2) for use in an internal combustion engine comprising a sintered body of a partially stabilized zirconium oxide having a porosity of less than 3%. Even under extreme stress, e.g., in an outlet valve of a high-power engine, but in particular in the blow-off valve of an exhaust gas turbocharger, the valve guide shows a considerably reduced wear as compared to conventional valve guides.

    摘要： In a pre-combustion or turbulence chamber for an internal combustion engine, an inner molded body, defining an inner chamber, is formed of a material having a thermal conductivity of at least 12 W/(m.multidot.K). An outer body is secured to the outer surface of the inner body by shrinking or glueing. The outer body is formed of a thermally insulating ceramic material having a thermal conductivity of less than 10 W/(m.multidot.K). Due to the low thermal conductivity of the outer molded body, the inner molded body is insulated against heat losses. The higher thermal conductivity of the inner molded body has the effect that, in the interior of the pre-combustion or turbulence chamber, the point at which the cold fuel jet impinges during the injection process is only slightly cooled.

    摘要翻译： 在用于内燃机的预燃烧或湍流室中，限定内室的内部模制体由具有至少12W /（m×K）的热导率的材料形成。 外壳通过收缩或粘合固定在内体的外表面上。 外体由导热率小于10W /（m×K）的绝热陶瓷材料形成。 由于外部成型体的导热性低，因此内部成形体被隔热以防止热损失。 内部成型体的较高的热导率具有这样的效果：在预燃烧或湍流室的内部，喷射过程中冷燃料喷射射入的点仅稍微冷却。
