  • Patent number: 8590355
    Abstract: Cutting blades and counterblades are presented having long edge life for chopping devices equipped with blades mounted on rotating drums and with counterblades which fit into the gaps between the blades, the blades and/or counterblades being produced by rolling at least one of the longitudinal edges of a piece of flat strip material to form a slightly rounded, prismatic cutting edge, the rolling being continued until satisfactory sharpness is obtained.

  • Patent number: 6568755
    Abstract: A child's seat is especially adapted for mobile use in an aircraft. The seat has a support frame which can be fixed by a belt. A seat pan (9) and a back pan (10) are fixed to the support frame in an articulated manner. The lateral lower ends of the back pan (10) are displaceably accommodated in lateral guiding elements (15) of the support frame. The back pan can be fixed in an upright position by a fixing device and can be displaced in the guiding elements of the support frame once the fixing device has been released. The seat pan can be folded against the back pan and can be made of two pieces. The child's seat can be folded in a compact manner and can be packed in an aircraft in a space-saving manner. The child's seat can especially be used in a conventional passenger set in or against the flying direction.

  • Patent number: 6319618
    Abstract: A stainless steel “fish tape” is disclosed. The tape is characterized by a steel formulation of 10 to 20 percent chromium, up to 18 percent nickel, up to 4 percent molybdenum, not more than 0.9% carbon and no more than 0.8% nitrogen. It is critical that the circumference of the tape relative to the cross sectional area of the tape be of a ratio of at least 1.30 and preferably greater than 1.55. In counter distinction to known prior art fish tapes which attempt to achieve a highly smooth surface, the tape of the instant invention is preferably roughened or abraded to improve the ability to carry for lubricants. The lubricant retaining characteristic functions both to reduce friction on insertion of the tape through a conduit and to leave traces of lubricant on the surface of surfaces which have been impacted against the tape whereby the wire which is then drawn through the conduit, will also be lubricated at the critical points in the conduit most likely to cause frictional contact with the wire.

  • Publication number: 20010028954
    Abstract: A continuous in-drawing line process and system for drawing stainless steel wire is provided wherein wire is (1) brushed in an inlet brush station to remove oxide film from the wire surface; (2) coated with a lubricant carrier coating which is dried then subsequently cooled; (3) drawn through a drawing machine using a lubricant; and (4) brushed to remove residual carrier compounds from the surface of the drawn wire. The system for carrying out this process includes a wire payoff; an inlet brush station having two pairs of brushes that rotate in a direction opposite to that of the wire to remove oxide film therefrom; a coating device; a dryer; a cooler; a drawing machine; first and second outlet brush stations each having two pairs of brushes that rotate in a direction opposite to that of the wire to remove residual drawing compounds therefrom; and a wire take-up device.
