Patent EP-0414335-A1 (EP)
Inventor: GIANNUZZI LOUIS N
IPC: F16B25/00
Filed: 1990-03-15
Abstract: A self-drilling plastic anchor installable in a wall (18) by means of a screwdriver, the anchor being adapted to receive a threaded fastener (19) that serves to hold a fixture (20) or other object against the wall. The anchor includes an externally-threaded shank section (14) having an enlarged head (15) that is engageable by the screwdriver and a cavity to receive the fastener. Extending from the lower end of the shank section is a drill section (11) that terminates in a point (P) that lies on the longitudinal axis of the anchor. When the anchor is applied to the wall, the point penetrates its surface, so that the anchor may then be turned by the screwdriver about the point. The drill section is formed by a pair of cutting blades (16A, 16B) on opposite sides of the anchor axis and a pair of guide blades (17A, 17B), each angled relative to a respective cutting blade. When the anchor is turned in, the cutting blades guided by the guide blades proceed to bore a hole in the wall, and when the shank section enters the hole, its bank is tapped by the threading of the shank section until the head thereof engages the surface of the wall to complete the installation. The fastener may then be screwed into the cavity of the shank section. The undersurface of the head has ratchet teeth (T) formed therein which when the head engages the wall surface, the teeth grip this surface to resist turning out of the anchor.

Abstract: The present invention relates to a method and an apparatus for treating fiber suspension. The method and apparatus are especially suitable for power screening of fiber suspension flowing to the head box of a paper machine. 
     In known filter apparatuses the accept pulp is thickened or diluted, the distribution of pulp fraction is changed and the filter apparatuses have created pulses in the accept pulp. In order to eliminate or minimize these problems a new type of a rotor (7) has been developed to be used with the filter cylinder, on the surface of which on the filter cylinder side protrusions (10) of different shape have been arranged, by which protrusions not only is the filter cylinder (6) kept clean, but also is affected on the axial flow of the fiber suspension.

Abstract: Une pseudo-variance locale pondérée centrale dans le voisinage d'un pixel d'image détermine le facteur d'amplification multipliant la différence entre le pixel d'image et son homologue flou avant qu'il ne soit combiné avec l'image originale. Le facteur d'amplification est calculé pour chaque pixel se trouvant dans l'image, et varie d'une valeur minimum d'environ -1 lorsque la variance pondérée centrale se trouve à une valeur minimum, jusqu'à une valeur maximum donnée lorsque la variance pondérée centrale atteint une valeur maximum. La pseudo-variance pondérée centrale est calculée par convolution du voisinage local entourant chaque pixel d'image à l'aide d'un noyau de poids centraux ayant une valeur maximum au niveau du pixel central. La pseudo-variance pondérée centrale est la différence entre la moyenne pondérée centrale du carré du voisinage local des pixels d'image et le carré de la moyenne pondérée centrale. On parvient à obtenir à la fois la netteté d'image et la suppression du bruit dans la même image, en permettant au facteur d'amplification de varier entre une fraction d'unité et au delà de l'unité à mesure que la variance pondérée centrale varie d'une valeur faible (image uniforme) à une valeur supérieure (image texturée).

Abstract: The present invention provides a method and apparatus for the automated reproduction of three dimensional objects of complex and unique geometry. A computer acquires data describing an object and its surroundings, constructs a computer-based three dimensional model of the object from that data, superimposes an ideal geometry on the computer-based model, alters the ideal geometry to fit the form and function required of the reproduction, and then guides a milling machine in the fabrication of the reproduction. In contrast to the prior art, the present invention does not require human intervention in the reproduction process. The present invention provides two preferred embodiments for the automated high precision reproduction of objects of complex and unique geometry. Both embodiments can machine reproductions solely from generic forms stored in the computer, thus eliminating the need for scanning. Alternatively, the reproductions may be machined solely from scanned data, without resort to generic forms stored in the computer.

Title: Split torque helicopter main rotor drive including an elastomeric torsional vibration damper
Inventor: KISH JULES G
IPC: F16F15/124
Filed: 1991-05-14
Abstract: The elastomeric torsional isolator comprises one or more elastomer layers (36) disposed between a spur gear (29), having a pair of sloped surfaces, and a pair of rims (30, 31) having corresponding surfaces. The rims (30, 31) are attached to a flange (26) extending from a shaft (21) which has pinions (22, 23) for engaging a driven gear. By preloading the elastomer layers (36), the spur gear (29) is frictionally connected to the flange (26) and shaft (21), rather than mechanically engaged. The preloaded elastomer layers (36) act as an elastomeric torsional isolator which accommodates variations in mechanical tolerances to balance the torque loading in a split torque drive system. Using elastomer layers (36) for balancing the torque loading between a pair of torque splitting gear assemblies reduces the number of bearings required, increasing reliability and reducing part complexity.
