Abstract: A power-measuring device serves to measure the power of a three-phase system. It comprises a measuring unit for measuring a power of a first phase of the three-phase system, a display unit for displaying measured results and an operating unit for the operation of the power-measuring device by a user. Furthermore, it comprises a communications unit by means of which it can communicate with one or more further power-measuring devices. In this context, the power-measuring device is embodied, jointly with the one or more further power-measuring devices, to measure a power of several phases of the three-phase system.

Abstract: A tool for machining surfaces, edge regions, and contours comprising at least one disk-shaped base body rotatable around a tool axis and a plurality of flexible machining means, which are arranged on a circumference of the base body, wherein the machining means are formed rod-shaped and are arranged spaced apart from one another and extend substantially radially outward from the circumference of the base body, wherein at least two disks, between which the machining means are arranged, are arranged in the direction of the tool axis.

Abstract: A saw band of steel for a band saw machine with a band back (Br) and with a tooth row arranged thereon having several teeth (20), wherein the initial tooth form (10) is triangular with a tooth base with tooth width (b) and with the tooth tip (1) with a first tooth height (h1), such that the tooth tip (1) does not project beyond tooth width (b) in the band running direction (L), wherein the lateral side of the triangle located in front in the running direction (L) forms the rake face (2) and the rear lateral side forms the clearance face (3) of the tooth (10, 20). The tooth tip (1) of the triangle is specifically removed for the development of a rounded-off tooth crest (4) with a reduced second tooth height (h2), wherein at least in the proximity of the tooth crest (4) a hard material coating covers at least partially the cutting face formed of the tooth crest (4), the rake face (2) and the clearance face (3).

Abstract: A saw band of steel for a band saw machine with a band back (Br) and with a tooth row attached thereon comprises several teeth (20), wherein the initial tooth form (10) is triangular with a tooth base with tooth width (b) and with the tooth tip (1) with a first tooth height (h1), such that the tooth tip (1) does not project beyond tooth width (b) in the band running direction (L), wherein the lateral side of the triangle located in front in the running direction (L) forms the rake face (2) and the rear lateral side forms the clearance face (3) of the tooth (10, 20). The tooth tip (1) of the triangle is specifically removed [of material] for the development of a rounded-off tooth crest (4) with a reduced second tooth height (h2), wherein at least in the proximity of the tooth crest (4) a hard material coating covers at least partially the cutting face formed of the tooth crest (4), the rake face (2) and the clearance face (3).

Abstract: The tool according to the invention has a variable loading of working means (3-6). The total set of working means (3-6) is divided into subsets, which, with respect to the direction of rotation (18), have different working angles (15, 16, 17). By changing the height (35) of subregions (23-28) of the base plate (1) of the tool, the free length of the working means (3-6) can also be varied. A single tool can be built, which combines several working functions and working properties in one tool. (FIG.

Abstract: A grinding tool has radially projecting grinding elements separated by spacers. The grinding elements are provided with radially extending slots. Some of the slots are open-ended. Axially spaced slots alternate in different radial positions.

Abstract: Microcapsules which can be prepared at low temperatures contain walls composed of the product of an interface polyaddition and/or interface polycondensation reaction between a hydroxylamine and at least one component which is reactive with amino and alcohol groups. These microcapsules are advantageously used in the production of carbonless copying paper and thermal paper.
