Abstract: Various embodiments are generally directed to techniques for partitioning parallelizable tasks into subtasks for processing. Some embodiments are particularly directed to dynamically determining chunk sizes to use in partitioning tasks, such as parallel loops or divide and conquer algorithm tasks, into subtasks based on the probability of a priority task source introducing a high-priority task. For example, a measurement signal received from a probe indicating an operational characteristic associated with a priority task source may be used to generate an estimate of the probability of a priority task source introducing a high-priority task. In such examples, the estimate may be used to determine a chunk size for a parallelizable task and the parallelizable task may be partitioned into a plurality of subtasks based on the chunk size and the subtasks may be assigned, for execution, to at least one task queue in a task pool.

Abstract: The present invention relates to a quick-change insert (10) for tools (11), in particular thread drills (12), for minimal lubrication, that is designed for detachable installation in a chuck (30) provided with a central lubricant channel (32) and for introducing the lubricant as an aerosol from the lubricant channel (32) into the rear end of a longitudinal bore (14) of an inserted tool (11). A sealing body (40) provided with a central passage (41) is located in a rear receptacle (25) of the insert body (17) such that, when the tool (11) is inserted and installed in the chuck (30), it connects the lubricant channel (32) and the longitudinal bore (14) of the tool (11) with each other in an at least substantially leakproof manner.

Abstract: A method of indelibly marking a label (10) which includes a substrate (11) (which is transparent or translucent) and an adhesive layer (12). The method includes applying a marking (14) to the adhesive layer (12) such that the marking is visible through the substrate. The marking (14) can include part thereof in a mirror or reverse image of that which is to be visible through the substrate. The marking can be applied by ink-jet, hot-wax or laser marking (13).

Abstract: The invention relates to a tool holder (10) for shrink-fit attachment of rotating tools (11) with predominantly cylindrical shafts (12), having a chuck (13) with a clamping section (14) containing a conical receiving bore (15) to accommodate an insert (30) that has a cylindrical bore (32) to accommodate the tool shaft (12) and has a conical outer surface (31 ) to be contained in the receiving bore (15) of the clamping section (14). The insert (30) is embodied so that after the axial insertion of the insert (30) into the hot chuck (13), a contact is produced between the insert (30) and the chuck (13) on the one hand and between the insert (30) and the inserted tool shaft (12) on the other hand and, when the chuck (13) cools, the tool shaft (12) is clamped, wherein it is possible to bridge over large diameter tolerances while achieving maximum clamping forces (FIG. 1).

Abstract: The invention is concerned with a device for clamping and releasing work tools (16) in a tool receptacle (10). The tool receptacle (10) includes on its free end for this purpose an open socket part (12), which is adapted for frictional engaging reception of the work tool shaft (14). The work tool shaft is thereby shrunk-fit into a borehole (20) in the socket part (12). For this purpose the socket part is provided with an induction coil (26) encircling the tool receptacle (10) which coil can be acted upon by high frequency alternating current for producing heat and heating the socket part (12). For avoidance of leakage fields which could result in a undesired heating of the work tool (16), it is proposed in accordance with the invention that the induction coil (26), on its surface adjacent the free end of the socket part (12), is covered over by a pole shoe (34) having a central through hole (36) for the work tool (16) and comprised of a magnetically conductive and electrically non-conductive material.
