Patent CA-2370223-C (CA)
Inventor: DANEK CHRISTOPHER JAMES
IPC: A61F2/86
Filed: 2000-04-21
Granted: 2010-07-20
Abstract: This relates to methods and devices for treating reversible chronic obstructive pulmonary disease, and more partic-ularly, relates to a device for exchanging energy with airway tissue such as that found in the airways of human lungs. The exchange of energy with this airway tissue in the airways reduces the ability of the airways to constrict and/or reduces the resistance within the airway to the flow of air through the airway. This also relates to a method for decreasing responsiveness or decreasing resistance to airflow of airways involves the transfer of energy to or from the airway walls to prevent or reduce airway constriction and other symptoms of lung diseases. The treatment reduces the ability of the airways to contract during an acute narrowing of the airways, reduces mucus plugging of the airways, and/or increases the airway diameter.  The methods according to the present invention pro-vide a longer duration and/or more effective treatment for lung diseases than currently used drug treatments, and obviate patient compliance issues. This also includes additional steps that reduce the ability of the lung to produce at least one of the symptoms of reversible obstructive pulmonary disease and to reduce the resistance to the flow of air through a lung.

Title: System and process for the oxygen delignification of pulp consisting of lignocellulose-containing material
Inventor: DAHLLOF HAKAN
IPC: D21C9/10
Filed: 2000-07-05
Granted: 2009-09-08
Abstract: The invention relates to a system and a process for the oxygen delignification of pulp which consists of lignocellulose-containing material and whose mean concentration is 8-18 % pulp consistency, in at least two stages. The invention is characterized in that oxygen delignification takes place in a process sequence consisting of: a first lamp (1), followed by a first oxygen mixer (3), followed by a first delignification zone (6) and, directly afthat, followed by a second steam mixer (8), followed by a second pump (4), followed by a third oxygen mixer (5) and, finally, a second delignification zone (10). This makes it possible, in an industrial process, to exploit the kinetics of oxygen delignification optimally in order to obtain selective oxygen delignification at low installation cost and low operating cost, even if only low-pressure steam is available.

Title: Collapsible concrete forms
Inventor: PASKE STEVEN J
IPC: E04B2/86
Filed: 2003-05-15
Granted: 2008-07-29
Abstract: A concrete form unit includes opposing sidewalls which are preferably made of foamed plastic or other insulating material. Articulated spacers extend between and connect the sidewalls, and are capable of folding about themselves both at an elbow situated between the sidewalls, and also at their junctures with the sidewalls. The folding ability of the spacers allow the sidewalls to convert between a collapsed state wherein the sidewalls are in close adjacent relationship and the spacer links are oriented at least substantially parallel to each other and at least substantially parallel to the sidewalls, and an expanded state wherein the sidewalls are in distant spaced relationship with the spacer links being oriented at least substantially parallel to each other and at least substantially perpendicular to tile sidewalls. The collapsed form unit therefore assumes an overall box-like shape, and therefore the collapsed form units are easily stored and shipped with minimal lost storage volume.
