Abstract: In a device (1) for holding a tool (3) on the drivable spindle (2) of a machine tool, with a mounting shank (11) which can be clamped in position in the machine tool and an integrally formed intermediate piece (12), the tool (3) is fastened to the intermediate piece (12) in such a way as to be adjustable to a limited extent in the axial direction of the intermediate piece (12) via two or more leaf springs (21) of curved design and preferably distributed uniformly over the periphery. This configuration ensures that workpieces (4) can be machined in accordance with the contour present in each case without the machine spindle (2) having to be changed in its vertical position for this purpose. On the contrary, the machine spindle (2) can follow a theoretically predetermined contour, while the tool (3) automatically adapts itself to the actual workpiece contour to be machined and bears with virtually constant applied pressure against the workpiece (4) so that, although unevenness improves, no unnecessary stock removal takes place and damage need not be tolerated. <IMAGE>

Abstract: A flow meter (10) employs phased arrays (14a, 14b, 16a, 16b, 18a, 18b, 20a, and 20b) of ultrasonic transducers mounted on the exterior of a pipe (12) to transmit and receive sound directed through paths that pass through the pipe interior. The flow meter (10) determines the rate of fluid flow through the pipe (12) by comparing the sound-propagation times for sound traveling the same paths in opposite directions. By driving the transducers as phased arrays, the flow meter (10) can employ sound-propagation paths that form angles to the normal to the interior pipe wall that exceed those dictated by Snell's law as applied to the relative propagation speeds in the pipe wall and the fluid.

Abstract: Apparatus for and a method of digital signal processing utilises a technique known as sub-band decomposition and reconstruction. A plurality of input channels are provided each of which is mixed with a vernier frequency correction. In a multiplexer implementation, an FFT weighted overlap-add demultiplexer (c) is provided for decomposing each input channel into sub-bands. The sub-band outputs are decimated by a factor (d) to the common input sampling rate of a multiplexer, the sub-bands from each channel then being passed into the appropriate ports of an FFT weighted overlap-add multiplexer (f) by means of a switch matrix (e). The multiplexer (f) reconstructs the individual channels, interpolates each channel up to the output sampling rate of the FDT signal, mixes each channel up to its assigned carrier frequency in the FDM and multiplexes the channels. This provides a computationally efficient architecture with the flexibility to accommodate channels of differing bandwidths.

Abstract: An improved apparatus and method for ultrasonic inspection of materials through barriers such as gaps in manufactured parts is disclosed. The improvement herein is directed to enabling such ultrasonic testing to bridge ambient gaps (G) such as intentionally formed gaps in composite structures having a first structure (H) for originally receiving and transmitting sound separated by the gap from another structure to be inspected (T). Preferably, the gap is flooded with a gas (32) having a predictable and optimum speed of sound relative to the material of the first and second structures. Sound is propagated to the first structure in a wave packet that is transmitted through the couplant fluid (31). The sound is generated in a wave packet having a spatial width at least twice the dimension of the gap to be bridged. The wave packet has a contained frequency having a wavelength (relative to the speed of sound of the gas flooding the gap) to create a constructively interfering standing wave within the gap. The sound propagated to the gas-filled gap has a wavelength which is a half-integer with respect to the gap dimension. Sound passes through the first structure, creates a standing wave in the gas-filled gap, passes into and acoustically interrogates the second structure for flaws (35) and reflects. Reflected ultrasound from the interrogated second structure again bridges the gap as a constructively interfering standing wave, passing through the primary structure and then through the couplant fluid (31) to a transducer (40) for receipt and analysis of the received ultrasound. Inspection across the gap between a control rod drive housing (H)for interrogation of a stub-tube structure (T) within a nuclear reactor is disclosed.

Abstract: Micromechanical devices are formed on a substrate using a sacrificial layer deep X-ray lithography process to produce a rotating microrotor which is driven magnetically. The rotor typically has a diameter of a few hundred microns or less and is formed as a free structure which is assembled onto a hub formed on a substrate. Stator pole pieces are formed on the substrate of a ferromagnetic material surrounding the rotor, and are also preferably formed by a deep X-ray lithography process followed by electroplating of a ferromagnetic material such as nickel. The stator pole pieces are supplied with magnetic flux, such as from a current flowing through a conductor surrounding the magnetic pole pieces which is integrated with the pole pieces on the substrate. Separate electromagnets can also be utilized to provide the magnetic flux to the pole pieces to provide a rotating magnetic field in the region of the rotor to drive the rotor.

Abstract: The invention relates to an arrangement of limit position switches in a linear adjusting drive which is driven by electric motors, especially a drive for points, in the case of which drive limit position switches signal that the right-hand or left-hand limit position of the drive has been reached. In order to ensure that these limit-position switches can emit an alignment message only when the drive is actually latched in the limit position, that is to say sticking or fused contacts of the limit position switches cannot be confused with a limit position having been reached, which can lead to dangerous situations, it is proposed according to the invention that slide-type momentary-contact switches having additional mechanical positive operation of the contacts in both switching directions be used for the limit position switches (13/13') instead of roller momentary-contact switches. Each limit position switch (13/13') is expediently fitted at the end of its operating shaft (16) with an axially directed link in which a transversely located operating bolt (19 or 19' respectively) engages, which can be moved by the associated release lever (12 or 12' respectively). The link can have the form of a pulley (17) with a broadened pulley groove (18), the operating bolt (19 or 19' respectively) engaging in the pulley groove (18) with axial play in the switch operating direction. <IMAGE>
