Abstract: Producing a hardened steel product can comprise providing a steel substrate of a hardenable steel; coating the steel substrate with an aluminum precoating, wherein the precoating is applied to the steel substrate with a thickness of at least 34 ?m; flexible rolling the pre-coated steel substrate to produce a variable thickness along the length of the precoated steel substrate, wherein the precoating is rolled out to a reduced first thickness of less than 33 ?m in thinner first portions and to a reduced second thickness thicker than the reduced first thickness in thicker second portions; working out a blank from the flexibly rolled steel substrate; heating the blank to austenitizing temperature, wherein diffusion processes take place between the base material and the precoating; and hot forming the heated blank, wherein the heated blank is formed and rapidly cooled such that a hardened steel product with coating is produced.

Abstract: A method for conveying a working medium within a supply line (2), wherein a pig package (48) is moved into the supply line (2) by means of a pushing medium conveyed by a first pump (40) to a proximal end of the supply line (2), is intended to enable TPS operation in a manner that is as technically simple as possible. To this end, a first conveying quantity of the pushing medium is determined by means of a first flow-measuring cell (44) associated with the proximal end, wherein a position of the pig package (48) in the supply line (2) is determined from the first conveying quantity and information about the cross-section of the supply line (2).

Abstract: The invention relates to a method for configuring a monitoring system which is based on a recording of altitude maps, comprising the following steps:—an altitude map of a monitored area is recorded with the monitoring system in a state in which no objects or persons to be detected are located in the monitored area,—determination of destruction points, caused by obstacles, in the altitude map which is recorded in this way,—definition of a detection area as a component area of the altitude map in such a way that all the disruption points, or at least some of said disruption points, lie outside the detection area,—setting of an evaluation unit of the monitoring system such that it only evaluates movements within the detection area. The invention also relates to a correspondingly configurable monitoring system.

Abstract: A shutoff valve, in particular for shutting off a paint conducting channel in a painting plant, includes a shutoff body, a pressure-operated stroke piston movable in an opening direction, thereby moving the shutoff body from a closed position into an open position; and a piston stop limiting a stroke travel of the stroke piston in the opening direction, and being adjustable to assume different working positions along the opening direction.

Abstract: The invention relates to a process for the continuous heat treatment of steel strip material whose thickness d1, d2 periodically varies along its length, more particularly of strip flexibly rolled with a roll gap varying as a function of time, wherein the continuous heat treatment of the strip material takes place while the strip material passes through an induction furnace in which the strip material is induction heated at a constant frequency which can be selected to be such that the mathematical induction depth ? of the induced current up to which the magnetic field has been reduced to 63% of the field strength of the outer field is greater than half the thickness of the strip portions with the smallest thickness d2.

Abstract: The invention relates to a stereo camera system with at least two image detection sensors which are fixedly connected to a circuit board. The image detection sensors are coplanar and a fixed distance apart.

Abstract: A spindle lock of a hand-held combination drill and chisel hammer has a gearbox housing and a countershaft rotatably supported in the gearbox housing about an axis of rotation. A locking plate is provided for selectively releasing and locking a rotational movement of the countershaft. Guide elements are disposed in the gearbox housing, wherein the locking plate is displaceably guided on the guide elements in the gearbox housing in a direction parallel to the axis of rotation of the countershaft. The guide elements have a guide rail arrangement wherein a part of the guide rail arrangement is provided on the gearbox housing and is integral with the gearbox housing.

Abstract: A hand-held hammer drill has a housing, a tool spindle rotatingly driving a tool, a hammer action percussion-driving the tool, a swash plate drive driving the hammer action, and a countershaft driving as needed the tool spindle and the hammer action. A first bearing and an axial bearing are provided. The hub is rotatably supported in a cantilevered arrangement by the first bearing in the housing and coaxially surrounds the countershaft. The hub has a free cantilevered end and the axial bearing is disposed on the free cantilevered end, wherein the axial bearing axially supports the countershaft and has radial play relative to the countershaft.
