Abstract: The process for making a wood board comprises the steps of:  a)  providing  elongated  pieces  of  wood  each  from  a coniferous wood and each having a rectangular cross section; b) detecting an average fiber density of each of the pieces of wood; c) selecting among the pieces of wood those having an average fiber density at least equal to a predetermined fiber density; d) planing off edges of the pieces of wood selected in step c); and e) bonding side by side the pieces of wood planed off in step d) by means of their edges to form the wood board. The board produced thereby shows excellent mechanical characteristics. An advantage of the present invention is to provide a process for making high strength lumber products from coniferous  trees  which  are  traditionally  considered  as nonstructural wood.

Abstract: A method is provided for cleanup of the fine fraction (<= 1.0 mm) of sandy soils contaminated with heavy oil/ bitumen, chlorides and heavy metals and for recovery of heavy oil/ bitumen from aqueous slurries of these soils. The method includes the steps of screening the sandy soil, preparing hot aqueous slurry of prescreened soil, screening and heating the slurry in a slurry heater, separating oily froth and contaminated process water from the slurry of precleaned sandy soil and thickening the precleaned sandy soil in a separating/thickening vessel followed by reprocessing the thicken slurry of precleaned sandy soil. Reprocessing generates some additional quantities of residual oily froth and contaminated process water from the sandy oil which is washed with fresh water, dewatered and renders sandy soil that meets the criteria for agricultural soil in Canada.

Title: Method and apparatus for rolling strip
Inventor: SEIDEL JURGEN
IPC: B21B45/02
Filed: 1997-12-22
Granted: 2009-09-29
Abstract: A method of rolling strip in a strip rolling train having at least two roll stands,, each roll stand having horizontally adjustable upper and lower work rolls, wherein the work rolls act alone as a two-high stand or each work roll is supported directly or through an intermediate roll by a back-up roll, or in a reversing stand in which at least two passes are rolled, wherein the strip is subjected in the roll stands to a constitutional change, and wherein adjusting elements act on the strip for imparting a profile and surface evenness to the strip. The method includes presupposing in at least one strip area an intended surface unevenness shape over a width of the strip, determining an actually achieved surface unevenness shape in the strip area and comparing the actually achieved surface unevenness shape to the presupposed unevenness shape, computing a difference between the unevenness shapes, and operating the adjusting elements such that the difference is minimized.

Abstract: The present invention concerns a process and a coating colour for coating a cellulosic web. According to the process an aqueous coating colour is applied on the surface of the web. The invention comprises using a coating colour which contains an aqueous polymer whose viscosity in an aqueous solution increases when the temperature rises.  Preferably, methylcellulose or a corresponding polymer having a gelling temperature of about 5 to 10 °C more than the application tempature of the coating colour is used.  The temperature of the coating is increased after the application of the coating colour in order to achieve gelling of the polymer. As a result, the coating colour rapidly solidifies which decreases the amount of mixture being recycled and it reduces mist-formation in the film press method and improves coverage of coating applied by conventional blade coating.

Abstract: L'invention concerne un ensemble de préparation de mélanges permettant de transvaser plusieurs fluides nutritifs de récipients sources individuels à un récipient collectif tout en détectant de manière non effractive le type de fluide transvasé. L'ensemble de préparation de mélanges fait appel à un ensemble de transvasement pour établir une communication fluidique entre les récipients sources et le récipient collectif. Un ensemble de détection est conçu de manière à détecter de manière non effractive un certain nombres de types de fluides s'écoulant à travers l'ensemble de transvasement pour permettre d'éviter un mélange incorrect. Dans le cas d'autres fluides que l'ensemble de détection seul ne pourrait pas déterminer avec la précision voulue, le dispositif de mélange fait appel à un procédé selon lequel une approximation de la vitesse d'écoulement de ce fluide est réalisée, cette vitesse d'écoulement donnant une indication sur ce type de fluide. En combinant le débit de l'ensemble de détection et la détermination de la vitesse d'écoulement, on peut identifier des fluides supplémentaires.

Abstract: A method and apparatus for receiving status information from shared logical memory modules in a computer system including redundant memory. The status information includes whether the shared logical memory modules are in a transitional state and the number of logical memory modules in the mirror set. When shared logical memory modules are added or removed from redundant memory they go through a transitional state when the memory card may respond to a request for data held on the card, but that data may be unreliable. Checking this status information allows better error checking of data and fault detection of the shared logical memory module.

Abstract: In the present invention, a partly duplexed conversion table is used as a conversion table for converting an M-bit based data string directly into an N-bit based code string without using margin bits. This conversion table is constituted by first and second sub-tables including plural code groups, respectively.      The plural code groups include different codes for the same input data. The second sub-table is a table which is partly duplexed with the first sub-table and is produced by allocating different codes to data from first input data to second input data in the first sub-table. The first and second sub-tables are so designed that code sets of the duplexed portions take variants of digital sum variations which are opposite in sign. Codes are allocated to all the code groups in the duplexed portions of the first and second sub-tables with respect to input data sequentially from a code having a maximum absolute value of variant of the digital sum variation. Thus, according to the present invention, low frequency components of modulated signals may be restricted properly.
