Abstract: A pre-whirl generating apparatus (26) is provided that employs deformable air deflecting vanes (46) adjacent the inlet (18) of a radial air compressor (12-22), which vanes (46) can be mechanically deformed to generate positive, neutral, or negative pre-whirl flow to the compressor. A minimum number of parts are used to position one or more thin, deformable vanes (46) in the intake channel (34) leading to the compressor inlet (18). In their undeformed position, the vanes (46) do not deflect the incoming air, thereby causing little or no flow restriction. To achieve the desired positive or negative pre-whirl of flow to the compressor (12-22), the trailing edge (62) of the vanes (46) are deflected transverse to the direction of flow in the channel (34) in either the positive or negative direction.

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.

Abstract: In the inventive process the morphological characteristics of point-shaped vehicle lane markers are evaluated on the basis of a priori knowledge. For this, those estimation processes are particularly useful, which are based on a Kalman Filter. After the selection of suitable ROI a Matched Filter is employed, in order to better extract from the background the image points associated with a vehicle lane marker. The inventive process is obviously not limited to point-shaped vehicle lane markers.

Abstract: Described is a conveyor for confections having the design that the material is conveyed along a flow path which is essentially free from abrupt detours or direction changes. In the case of utilization of helix rotors as conveyors this occurs in that the helical rotors (3, 11) are mounted respectively on only one of their ends and the discharge column (10, 20) is provided in essentially the axial direction. These columns may be conical and preferably coaxial but in certain cases may also be slightly eccentric to the axis of the helical rotors.

Abstract: A method and corresponding devices for monitoring the performance of a radar system (2, 4) which is equipped with a shield 2 (radome) to protect it against weather influences are described. For this purpose, a part of the radiated radar signal is modified and fed as a monitor signal to the reception system after interacting with a coating (5) which is possibly present on the radom (2). Influences of a damping or reflecting coating (5) on the radom (2) change the monitor signal. By analyzing these changes it is possible to draw conclusions about the coating of the damping or reflection of the radar signals which is caused by the coating (5).

Abstract: The invention relates to a method for producing defined layers or layer systems made of polymers or oligomers on any solid surface and with a controlled structure, according to which the layers are chemically deposited on the solid surface by means of living/controlled free-radical polymerization. Said method comprises the following steps: a) bonding the compounds of the general formula (a) A-L-I to the solid surface via the active group A, where A represents an active group, I is the initiating group for ATRP polymerization and L is the binding link between A and I; and b) carrying out living/controlled free-radical polymerization by reacting the initiator group I with monomers, macromonomers or mixtures able to undergo free-radical polymerization, which produces the polymer layer on the solid surface. The invention also relates to solid surfaces with oligomer or polymer layers and initiators for carrying out the method.
