Abstract: The present invention discloses a method and a device for preventing thermal damage of workpieces due to heat developed by a grinding process. According to the method the temperature increase at the surface being ground is determined and the resulting actual value is compared to a reference value which has been established under the same grinding parameters with a grinding disk that caused thermic damage to the reference workpiece. During manufacture, the grinding process with the respective grinding disk is interrupted as soon as a temperature increase has been detected that corresponds to the respective temperature causing thermic damage. The reference value is determined such that it includes a certain safety margin. The determination of the actual value and the reference value may be accomplished by using geometric deformations of the workpiece that result from the temperature increase due to the grinding process. The device is characterized by special measuring devices for measuring the geometric deformations of the workpieces.

Abstract: Method for shared data update and query operations wherein two control fields are associated with each data block of interest. Before any data in shared memory is modified, a value different from the present value is written into one of the shared memory control fields. The shared memory data is then updated. Thereafter, the other shared memory control field is updated to the new value, thus making the values of the shared memory control fields identical once again. During query operations, the data and control fields of interest are copied into private storage. The values of the control fields in private memory are compared. If the values are equal, the data in private storage is considered to be consistent. Otherwise, the data is considered to be in the process of being updated and the data is ignored until the values of the shared memory control fields become equal.

Abstract: A process for reducing background clutter of a scene, and thus, isolating an object of interest. The process includes calculating a minimum output from a plurality of appropriately configured anti-median filters representing a minimum difference processor (MDP) filter. In a first preferred embodiment, the MDP filter includes a (5 x 5) matrix of elements wherein each element has an intensity value representation of the scene. A first anti-median filter array is configured as a horizontal array of 5 pixel elements in which the center element of the matrix is the center element of the horizontal array. A median value of the 5 elements of the horizontal array is determined, and is subtracted from the value of the center element to determine an anti-median value of the horizontal array. The same process is performed for a vertical 5 element anti-median array, and two diagonal 5 element anti-median arrays, all including the center element of the matrix as the center common element of the arrays. Once the anti-median value of each array is determined the lowest anti-median value is outputted as the output of the MDP filter. In a second preferred embodiment, the values of the remaining elements of the matrix which were not included in any of the horizontal, vertical or diagonal arrays described above are subtracted from the center element of the matrix. Again, the lowest value from the group of anti-median values together with the remaining subtracted values is outputted as the output of the MDP filter. This process enables the background clutter of the scene to be substantially suppressed or eliminated.

Abstract: The invention provides a device, which utilizes the tunnel effect under the condition of geometric total reflection, for measuring a narrow gap and surface unevenness of a specimen with high precision. An optical device 40 includes a semi-conductor laser 42, a photodiode 43, and a waveguide layer 44 formed on a semi-conductor substrate 41 by epitaxial growth. A reflecting surface 44b of the waveguide layer 44 is parallel to the (100) plane of the semi-conductor substrate. The laser beam emitted from the semi-conductor laser is reflected from the reflecting surface 44b under conditions of total reflection in geometrical optics. When the gap between the reflecting surface and the specimen is less than or equal to about the wavelength of the laser beam, part of the laser beam is transmitted into the specimen. The intensity of the transmitted light, which is calculated corresponding to the intensity of the reflected light, depends on the dimension of the gap. In the practice of the invention, the relationship between the transmittance and the dimension of the gap is previously obtained, and the dimension of the gap is determined corresponding to the transmittance measured. A narrow gap and the surface unevenness are accurately and precisely measured.

Abstract: In known brush gear for two-pole direct-current permanent-magnet motors using injection-moulding technology, the components are located in a plane on the carrier board, as a result of which the position distribution is not uniform with respect to dissipation of the resistance heat loss occurring in the inductors. According to the invention, this disadvantage is avoided in that the carrier board (1), which consists of electrically insulating material, is constructed in the form of a pot and is supported by means of its cylindrical circumferential surface (7) in the cylindrical motor housing (9) such that it can be pushed in to a limited extent, and, on the inner base surface (47) of the baseplate (27), it has holding elements for uniform distribution of heat-producing electrical components such as inductors (49, 51, 53, 55), a capacitor (57), a resistor (59) and fixed contacts (2, 4, 6, 8, 10, 12, 14, 16). Effective utilisation of the structural space is made possible as a result of a space-saving arrangement of the suppression elements, by means of height-offsetting in the carrier board (1) in such a manner that the heat-generating components are distributed uniformly on the carrier board (1). These components are attached by means of a self-locking plug-in latch on the carrier board (1), as a result of which it is possible to match the brush gear to different performance and equipment requirements, by means of alternate inserts in the injection mould. …<IMAGE>…

Abstract: A family of modular solid-propellant launch vehicles and a related launch facility for placing a wide range of payloads in earth orbit at greatly reduced costs compared to present day launch systems. The basic family of modular solid-propellant launch vehicles is constructed from only two sizes of modular solid-propellant rocket motors, a large rocket motor (10) and a small rocket motor (12). The modular rocket motors are clustered and stacked in various configurations to form the family of launch vehicles. The physical and performance characteristics of the two solid-propellant rocket motors, including weight, vacuum specific impulse and action time, were tailored to maximize the payload capabilities of each member of the launch vehicle family without exceeding predetermined maximum and staging dynamic pressure limits and maximum acceleration limits. The universal launch facility utilizes a steel canister (50) that is sized to hold the maximum diameter and length launch vehicle. The steel canister is secured in a concrete-lined launch pit (52) and the vehicle is expelled from the canister by a piston (54). The piston is caught by an arrestor device (56) upon reaching the end of the canister. An assembly platform (58) at the top of the piston provides a platform for assembling the launch vehicle.
