Patent CA-2201117-A1 (CA)
Inventor: ENGSTROM MIKAEL
IPC: B01D5/00
Filed: 1995-10-03
Abstract: Des eaux résiduaires acides et alcalines provenant d'une installation de blanchiment contiennent des quantités différentes de matières inorganiques et organiques ainsi qu'une teneur en sels variable. Si on mélange ces eaux résiduaires acides et alcalines, cela complique la séparation des différentes substances du flux de processus industriel lors d'un traitement ultérieur et produit aussi de plus grandes quantités d'eaux résiduaires, ce qui est un désavantage avec des procédés visant à concentrer les substances chimiques produites par une telle installation de blanchiment. D'autres problèmes découlent aussi de la formation d'inscrustations dans des surfaces échangeuses de chaleur. L'invention concerne un procédé amélioré, permettant de traiter des eaux résiduaires de processus industriel qui proviennent d'une installation de blanchiment et consistant à concentrer séparément dans des évaporateurs les flux acide et alcalin de ce processus industriel à réduire la teneur en sels du flux acide par électrodialyse et à soumettre à une combustion le flux alcalin. Ce procédé permet de limiter la quantité d'eau recyclée et d'éviter des problèmes liés aux équipements de traitement tout en contribuant à un degré supérieur de concentration des substances chimiques, même si le blanchiment implique d'utiliser du dioxyde de chlore (ECF).
Patent CA-2201397-A1 (CA)
Inventor: HIGHBERGER GERALD
IPC: C09D11/00
Filed: 1995-09-29
Abstract: The present invention comprises a series of discoveries related to the problems associated with formulations that destroy the color change properties of thermochromic encapsulated dyes. One aspect of the present invention is the discovery of a method of correcting these formulations to allow the addition of thermochromic dyes. Certain solvents destroy the dye, therefore any aldehydes, ketones, and diols, and most aromatic compounds should be removed from the formulation and if needed they should be replaced with solvents preferably having a large molecular weight (i.e. greater than 100 and low reactivity). Secondly, the formulation should be adjusted to be neutral (i.e. 6.5-7.5 pH) or have a low acid value. These two adjustments will allow the thermochromic dyes to be added to the formulation without a loss of its color change properties.

Patent CA-2204233-A1 (CA)
Inventor: MUBAREKA ABOUD
IPC: A01M21/04
Filed: 1997-05-01
Abstract: The vegetation control material applicator comprises a toroidal reservoir for containing a nominal amount of vegetation control material in fluid form and a circular valve assembly mounted between the reservoir and the circular saw blade of a brush saw. The reservoir and the valve assembly are mountable on the arbour of the brush saw with the valve assembly being in contact with the underside surface of the saw blade. The reservoir and valve assembly each have a diameter which is substantially less than the diameter of the saw blade. The reservoir has an opened side which is in communication with the valve assembly. The valve assembly comprises a valve disc and a valve seat. The valve disc is made of a material having the ability to resonate and to sustain a vibration therein. The valve seat is made of a material having vibration dampening properties. Therefore when an impulse is imparted by the saw blade to the valve assembly, a distortion of the valve disc relative to the valve seat causes the valve assembly to release a slight amount of vegetation control material on the underside surface of the saw blade. In another aspect of the present invention, the valve assembly comprises a set of spacers between the valve disc and the valve seat. The spacers are made of absorbent material and have a total thickness related to the viscosity index of the vegetation control material within the reservoir of the applicator.

Title: Flexibility and exercise apparatus
Inventor: TROJMAN SALVY S
IPC: A63B57/00
Filed: 1997-05-23
Abstract: A flexibility and exercise apparatus to stimulate and stretch the backmuscles used by a golfer in taking a golf swing. The apparatus has a frame on which is mounted a rotatable platform and a gripper. The user stands on the platform, takes hold of the gripper, and turns his hips to either side whilekeeping his shoulders fixed in position. This creates a deep and controlled stretch in the lower back and waist. The platform incorporates a resistance element that increases with rotation, and has built-in stops to limit the maximum degree of rotation. These elements prevent injuries that could result from inadvertent overstretching. The gripper is accessible to users of all sizes. The apparatus can include other exercise devices, such as a hand grip, foot step, tensor bands, and a seat for performing exercises from a seated position. The apparatus may be placed outdoors at a golf course, for use by golfers before playing a new game or at any individual tee.

Title: Semiprocessed nonoriented magnetic steel sheet having excellent magnetic characteristics and method for making the same
Inventor: FUJITA AKIO
IPC: C22C38/00
Filed: 1997-02-06
Abstract: The present invention relates to a semiprocessed nonoriented magnetic steel sheet which is used in iron cores of motors and transformers, finished to a final product by rolling having a reduction rate of 2 to 18% after final annealing by a manufacturer, and assures desired magnetic characteristics due to coarsening of crystal grains during strain-relief annealing after processing by a user.        The excellent magnetic characteristics can be achieved by increasing lubrication during second cold rolling so as to satisfy the equation: e c <= e s <= 1.18e c wherein e s represents a strain value at the surface layer of the steel sheet and e c represents a strain value at the central layer.

Title: A method for producing lignocellulosic boards
Inventor: ERIKSSON N LENNART
IPC: B27N3/08
Filed: 1996-07-25
Abstract: A method for the continuous production of boards of a ligno-cellulosic fiber material wherein the material is broken up into particles and/or fibers.  These are dried, glued and formed to a mat. The mat is compressed to a finished board while steam is introduced.  According to the present invention, the compression is performed as a single step and the steam is introduced through one or many compression rollers. By injecting steam in this way a sufficient cure is obtained to withstand the spring back characteristics inherent of the fibers so that it is possible to obtain a finished thickness of the board with one single compression step.

Patent CA-2226749-A1 (CA)
Inventor: SJ DIN KJELL
IPC: B27N3/08
Filed: 1996-07-25
Abstract: A method of the production of boards of a lignocellulosic fibrous material wherein a material is broken up into particles and/or fibers that are dried, glued and formed to a mat and pressed to a finished board so that steam is introduced to the mat. According to the present invention, the steam is introduced in a limited amount in a first injection step. This amount is adjusted so that the steam only penetrates into, heats and cures the surface layer of the mat. Thus, a board having a surface layer with a higher density than a middle layer is obtained so that the subsequent calibration compression provides a greater thickness that permits the middle layer to expand while the density of the surface layers is maintained.
