    Abstract: A cutting device of an apparatus for comminuting food products has two cutting rings located concentrically to one another and rotatable relative to one another about a common axis, so that an annular slot is bounded therebetween. The cutting rings have a plurality of axially extending teeth formed between axially extending slots, and the teeth of at least one cutting ring carry cutting members of hard alloy. Each of the cutting members of this one cutting disc completely overlaps a front surface of a respective one of the teeth and has two axially extending edges facing toward the annular slot between the cutting rings. One of these edges is a cutting edge, whereas the other of these edges forms, together with the cutting edge of a circumferentially adjacent tooth, a cutting gap.

    Abstract: A sitting pole for poultry having a surface designed substantially straight on an incline, forcing the poultry perching on the sitting pole to sit in a defined alignment. The inclined plane is set at an angle of approximately 35°. The surface has a U-shaped profile with a U-base forming the inclined plane. U-legs are provided and are bent off from the U-base. The U-base can be formed by two surface sections that are set at different angles from each other.

    Abstract: A method for production of a multi-layer gap-less steel pipe. An inner pipe and an outer pipe are formed from thermomechanically rolled steel strip with high notched bar impact strength by welding. The individual helical welding seam steel pipes of about the same lengths are matched with a difference of less than about one percent between the outer diameter of the inner pipe and the inner diameter of the outer pipe. The matched inner pipe is inserted into the outer pipe and the pipes are mechanically expanded with diameter control to a preset outer diameter of the multi-layer steel pipe. The resulting multi-layer steel pipe has the inner pipe disposed under compression and the outer pipe layer disposed under stress. The presence of a compression stress in the inner pipe provides a means opposed to hydrogen sulfide stress corrosion. The advantages of the helical welding seam steel pipes can be combined such as economic production, advantages relating to crack formation and crack propagation stopping, and the availability of high internal pressure loads upon use of thin, economic steel strip of different yield strength.

    Abstract translation: 一种生产多层无缝钢管的方法。 内管和外管由通过焊接的高切口棒冲击强度的热机械轧制钢带形成。 大致相同长度的单个螺旋焊缝钢管与内管的外径和外管的内径之间的差小于约1％。 将匹配的内管插入外管，并将管道机械膨胀，直径控制到多层钢管的预设外径。 得到的多层钢管的内管配置在压缩状态，外管层处于应力状态。 在内管中存在压缩应力，提供了与硫化氢应力腐蚀相反的手段。 螺旋焊缝钢管的优点可以结合经济生产，与裂纹形成和裂纹扩展停止有关的优点，以及使用具有不同屈服强度的薄经济钢带的高内压载荷的可用性。
