Abstract: A comminuting apparatus has a housing and a crushing area. The housing includes left and right bearing plates, left and right reinforcing, bearing and holdback plates, each with clearing and crushing prongs. The crushing unit includes left and right crushing shafts which are rotationally supported by the housing are interconnected to rotate in opposite directions, synchronously.  Each crushing shaft includes a number of radially-extending tool carries having tool heads which carry clearing devices and front and rear wear inserts, in seats within the tool heads. The crushing unit can be configured to provide clearing spacing between adjacent clearing devices of adjacent tool carriers, or to provide an overlap thereof. The clearing and crushing prongs are arranged between each of the tool carriers. An intermediate crushing area is formed between the left anti right crushing shafts. The tool carriers can include relatively high and low tool heads to provide differing peripheral rates of rotation for the tools which define inner and outer spheres of actions.

Abstract: La présente invention concerne un procédé et un dispositif de réalisation de nappe en plusieurs épaisseurs permettant de réaliser une épaisseur supérieure au-dessus d'une épaisseur de base. Ce procédé consiste à prendre un jet de fibres en suspension et de le déposer au moyen d'un caisson secondaire (21; 21', 26) dans des cylindres de calandrage réalisés avec deux toiles tendues (16, 22; 16', 22'; 22, 27) dont l'une (16; 16', 22) porte la couche de base humide. La formation en nappe de l'épaisseur supérieure s'effectue uniquement par un profilage (23, 23', 28) consistant à apporter le jet de fibres en suspension dans les cylindres de calandrage à deux toiles à une vitesse assez élevée pour provoquer une inflexion de la toile extérieure tendue. A cet effet, on conserve sensiblement constante la tension pendant l'inflexion de la toile extérieure en guidant celle-ci sur des supports en rotation (31a-c; 31a'-c'; 32a-c) dont l'un est monté en élasticité ou en mobilité de façon à corriger l'inflexion considérée. En l'occurrence, la vitesse de la suspension de fibres apportées dans la calandre à deux toiles est d'au moins de 300 m/mn, la tension de la toile extérieure ou intérieure étant d'au moins kN/m.

Such a structure allows the joining equipment to flexibly respond to complicated changes in joining states. Besides, using similarity with a thermal conduction equation enables to minimize the number of input items fed into the neural network. Furthermore, using an approximate solution to the thermal conduction equation realizes to accelerate the time for numerical calculation without loss of accuracy.

Title: A method and a system for coding rois
Inventor: CHRISTOPOULOS CHARILAOS
IPC: H04N7/26
Filed: 1999-10-06
Granted: 2009-12-22
Abstract: In a method and a system for encoding and transmission of still images having at least one region of interest (ROI), the ROI coefficients of an image transformed into the frequency domain, preferably using a wavelet transform are encoded so that they are transmitted first and can be decoded by a receiver without transmission of the boundary of the ROI. In a preferred embodiment the coefficients belonging to the ROI are shifted so that the minimum ROI coefficient is larger than the largest background coefficient.  A receiver can then perform an opposite procedure and thereby obtain the ROI. By specifying how much the coefficients need to be shifted in order to avoid sending shape information several advantages are achieved.  Thus, it is possible to avoid sending shape information and to avoid shape encoding at encoder side. Furthermore, there is no need for a shape decoder at receiver side, and there is no need for the receiver to produce the ROI  mask. Also, in another preferred embodiment, the shifting (or scaling operations) required at encoder and decoder are also avoided.
