Abstract: A device is provided for illuminating value documents to a sensor for testing value documents, and to a value document-processing system. The device has a support element and multiple radiation sources which are arranged in a row on the support element, and which are designed to emit electromagnetic radiation in order to illuminate a value document. The support element is equipped with a recess which is arranged at a distance to the radiation sources arranged in the row and which ex-tends over a first section of the row, wherein the support element has a heat-transfer capability in a support element region lying on the first section of the row, said heat-transfer capability being reduced in comparison to a support element region lying on another section of the row.

Abstract: A diameter adjustment oriented balancing system is disclosed for use with small diameter rotary boring heads. The diameter adjustment oriented balancing system includes a rotary boring head with a radially movable tool carrier. The rotary boring head designed to receive a number of removable counterweights in one or more slots precisely aligned in the axis of radial movement of the tool carrier. The diameter adjustment oriented balancing system further comprises a series of boring bars which are designed to be perfectly balanced such that the combination of the rotary boring head and cutting tool holder is perfectly balanced when the center of the cutting tool holder is located at the center of the rotational axis of the rotary boring head.

Abstract: The invention is an apparatus for adjusting the position of a cutter cartridge mounted on a machine tool head using noncircular adjustment pins that provide full linear contact between the machine tool head and the cutter cartridge.

Abstract: A removable boring tool cartridge has a cylindrical tool carrier axially adjustable in a bore in a cartridge housing by means of an adjusting screw having a head rotatably adjustable in the bore of an annular thrust bearing, which is secured around the outside thereof in one end of the bore in the housing by an injection molded plastic safety ring. The adjusting screw has an externally threaded shank that projects in radially spaced coaxial relation into a bore in one end of the tool carrier, to the opposite end of which is fastened an insert holder. A plastic sleeve nut is injection molded into the radial space in the bore in said tool carrier to surround and have driving engagement with the externally threaded shank of said screw.
