Abstract: Method and strip steel knife from a steel strip having a bainite and decarburized surface. The steel strip has a generally rectangular cross-section, and the method includes machining a plurality of beveled surfaces in a region of a longitudinal edge of the steel strip to create at least a cutting surface defining a longitudinal cutting edge; first hardening at least a part of the cutting surface to form a first cutting edge region of the longitudinal cutting edge; smoothing the cutting surface of at least the first cutting edge region toward the longitudinal cutting edge; and at least one further hardening in the first cutting edge region to form a distal cutting edge region of the longitudinal cutting edge within the first cutting edge region having an increased material hardness with respect to the first cutting edge region located outside the distal cutting edge region.

Abstract: Cutting tool for flat materials. The cutting tools includes a band-shaped base body which has on one longitudinal side a working region with cutting teeth and on an other longitudinal side a supporting region with a supporting surface. The cutting teeth are formed with tips and include cutting sides emanating from the tips at an angle a to one another. In a longitudinal direction of the working region, the tips of adjacent cutting teeth have different distances to the supporting surface.

Abstract: A stamping tool formed from a steel strip and method of forming the stamping tool. The stamping tool is formed from a steel strip shaped on a narrow side with a cutting part having a cutting edge. The stamping tool includes a back part with a contour in cross section on a narrow side of the steel strip, recesses shaped in the back part with free spreading of the material to be transverse to a longitudinal extension of the steel strip and perpendicular to lateral surfaces of the steel strip, such that an extent of the spreading is smaller than a thickness of the steel strip, and undeformed regions located between the recesses.

Abstract: Stamping tool, in particular a cutting rule, for dividing or perforating flat materials, and production of the tool. To create a stamping tool with improved properties, in particular with an automatic leveling in a flat-bed stamping machine and/or in a rotation stamping machine, embodiments provide that from a thermally treated and/or quenched and tempered steel strip, shaped on the narrow sides with, on the one hand, a back part with a convex contour in cross section or a contour composed of several projecting convex regions, which contour has recesses in some places transverse to the longitudinal extension and perpendicular to the lateral surfaces, shaped in a chipless manner by cold forming or embossing with free spreading of the material, wherein the extent of the spreading is smaller than the steel strip thickness and the undeformed regions between the recesses can be plastically deformed with a startup of the tool.

Abstract: The present invention relates to a cutting rule 1, comprising a steel band 10 with a cutting edge 20, a back 30 of the steel band 10 opposite to the cutting edge 20, wherein the back 30 comprises protrusions 32 which during the first use of the cutting rule 1 can be plastically deformed and wherein the protrusions 32 essentially comprise a height h of 30%-70% of the thickness D of the steel band 10. Further, the present invention relates to a cutting rule 1, comprising a steel band 10 with a cutting edge 20, a back 30 of the steel band 10 opposite to the cutting edge 20, wherein the back comprises protrusions 32 that can be plastically deformed during the use of the cutting rule 1 and wherein the protrusions 32 have been produced by grinding or milling of recesses 36 in transverse direction Q of the steel band into the back 30; as well as a cutting rule 1 whose back 30 is surface decarburized such that it can plastically deform during the first use of the cutting rule 1.

Abstract: The invention relates to a lithotriptor carriage comprising a moving device. For rendering the lithotriptors accessible to a possibly large field of application, a lithotriptor carriage comprising a moving device and an accommodating bed connected therewith, on which a lithotriptor can be mounted and detachably arrested on the carriage by means of an arresting device, is provided, wherein the lithotriptor is ready to be used in the mounted state.

Abstract: Following installation of a device for functionally testing an electronically controlled regulating system in a motor vehicle, it is operated, and during its operation data is detected and stored in a test system at a production facility. The data collection occurs for the duration of a particular vehicle's operation over a defined distance at the production facility.

Abstract: A lithotripter having a shockwave generator having a cavity filled with water, further having an ultrasonic, locating transducer mounted by means of a holding device which includes metallic inner and outer shells each having a large acoustic impedance as compared with water and an acoustically attenuating layer interposed between the two shells; the shells are spaced from each other so that the shockwaves will be eliminated by interference.

Abstract: An improved vibration absorber that overcomes deficiencies of known heavy vibration absorbers that require exact manufacturing tolerance for the rigidity of the absorber in order to generate a sufficiently large frequency range of the vibration absorber. The new vibration absorber has the purpose of covering a larger frequency range with a lower weight by having the absorber mass disposed to be pivotable around a pivot at one end and on an opposite side supports itself on the vehicle body through at least one bearing arrangement. The absorber mass and/or the bearing arrangement are slideably arranged with respect to the pivot. The vibration absorber may be used in vehicles which have a natural vibration in the low frequency range.
