Patent CA-2109510-A1 (CA)
Inventor: JOHNSON DAVID B
IPC: G01J3/45
Filed: 1992-05-08
Abstract: Méthode rapide et efficace de détermination quantitative par étapes d'une position relative à l'aide d'un intervalle de référence. Chaque étape de la position relative comporte des intervalles de commande à boucle ouverte et à boucle fermée. Sont décrits un actuateur (27) capable de modifier la position relative et une servocommande (17) à boucle fermée qui agit sur l'actuateur (27) de manière à garder la position relative centrée sur la valeur la plus proche d'une série de valeurs de référence. La servocommande (17) verrouille la position par rapport à une valeur de référence initiale donnée. On fait tout d'abord en sorte que l'actuateur (27) modifie la position relative d'une quantité à peu prés égale à l'intervalle de référence de façon que la servocommande (17) ne puisse détecter le changement, par exemple en désactivant la servocommande (17). La servocommande est alors réactivée, ce qui lui permet alors de garder la position relative centrée sur la valeur de référence la plus proche.

Title: Apparatus for encoding and decoding header data in picture signal transmission
Inventor: KATO MOTOKI
IPC: H04N19/60
Filed: 1994-01-14
Abstract: ABSTRACT         Control data subsequent to an extension start code is stored in an encoding apparatus when transmitted after each header data of a video sequence layer, a GOP layer, a picture layer and a slice layer.  And in transmission of the next header data, the content of the control data subsequent to the extension start code in the header data to be transmitted is compared with the content of the preceding header data of the same layer stored in the encoding apparatus.  And if the result of such comparison signifies that the compared data are mutually the same, neither the extension start code nor the subsequent control data is transmitted.  At the reception of each header data of the video sequence layer, the GOP layer, the picture layer and the slice layer, the control data decoded subsequently to the extension start code is stored in the decoding apparatus.  And when the extension start code is not existent in the next header data to be decoded, the preceding header data of the same layer stored in the decoding apparatus is duplicated and used as the control data of the layer being currently encoded.

Abstract: A method of total chlorine-free bleaching to a brightness of ISO 82-90 uses an acid stage and a superatmospheric pressure peroxide stage. The acid stage (which may be the only acid stage) may comprise a Q stage or a Z (ozone) stage, in which metals in the pulp are freed from pulp fibers and become dissolved in the surrounding liquid. The pulp is then subjected to fractional washing to produce at least two wash filtrates, the first filtrate having over 50% of the dissolved metals from the pulp. The first filtrate is ultimately returned (e.g. through brown stock washing) to the black liquor recovery system of the pulp mill so that the metals precipitate on organics in the black liquor recovery system due to the alkaline pH of the black liquor.     Other filtrates from the fractional washing are used to wash the pulp just before the acidic (e.g. ozone) stage. Acid and/or a chelating agent are added to the wash liquid during fractional washing so that the pH of the first filtrate is six or less, and magnesium may be added to the pulp while it has an acidic pH just prior to the peroxide bleaching stage. From the fractional washing stage the filtrates may each have a flow volume of 0.5-7 cubic meters per ton of pulp. A further (ZP) stage may be added if it is desired to achieve a brightness of ISO 89 or above.

Filed: 1993-05-05
Abstract: A generally rectangular wire grid (40) of welded construction is utilized to define and maintain the positioning of rebar (132) charged therethrough during the formation of structural column and girder cages. Prepositioned ties (46) guide the rebar through the grid. The prepositioned ties (46) are then tightened such that the rebar is held firmly in place at the close tolerance positions defined by the prefabricated grid. A plurality of such grids are assembled into expandable bundles (100) such that they may be expanded in an accordion-like fashion about rebar (132) charged therethrough, resulting in properly spaced grids for de-fining and maintaining the position of the rebar. Additional rebar members (132) may then be charged therethrough to complete the construction of a column or girder cage. The modular reinforcement cages of the present invention thus eliminate piecemeal engineering requirements by providing modular building concepts in which a unique rebar bundle pattern facilitates improved containment.
