Title: Procede de traitement d'un milieu renfermant des constituants organiques
Inventor: BAUR KARL
IPC: C02F11/08
Filed: 1995-05-04
Abstract: Procédé de traitement par oxydation chimique d'un milieu, par exemple des boues d'épuration, renfermant des constituants organiques, ledit procédé comportant deux étapes. Dans la première étape de traitement, on porte le milieu à une température comprise dans une première plage prédéterminée de basses températures, et on le maintient à cette température pendant une durée de traitement prédéterminée. Dans une deuxième étape de traitement, on porte les boues à une température comprise dans une deuxième plage prédéterminée de basses températures, on les met sous une pression comprise dans une plage prédéterminée de basses pressions, et on les maintient à cette température et sous cette pression pendant une durée de traitement prédéterminée. Pendant ce temps, on introduit dans le milieu, au moins de manière intermittente, un gaz oxygéné tel que de l'air ou de l'air enrichi en oxygène ou de l'oxygène de qualité technique. Les basses températures et les basses pressions produites dans les deux étapes du procédé sont inférieures aux plages de températures et de pressions allant de 150 à 370 °C et de 10 à 220 bar, ou tout au plus comprises dans le tiers inférieur de celles-ci, ces plages étant les plages traditionnelles des processus d'oxydation en milieu liquide. Entre les première et deuxième étapes du procédé, ou au cours de la deuxième étape, on ajoute au milieu une quantité prédéterminée d'eau oxygénée. Grâce à ce procédé, on obtient une réduction sensible de la demande chimique en oxygène (D.C.O.) du milieu, et une diminution importante du volume des matières solides contenues dans ledit milieu.

Title: Procede de production d'hydrogene gazeux par reaction chimique de metaux ou d'hydrures de metaux soumis a des deformations mecaniques intenses
Inventor: SCHULZ ROBERT
IPC: C01B3/08
Filed: 2001-02-15
Abstract: L'invention concerne un procédé amélioré de production d'hydrogène gazeux consistant à soumettre un métal ou un hydrure de métal à une réaction chimique. Dans ce procédé, le métal ou l'hydrure de métal soumis à la réaction chimique est nanocristallin. En effet, on a découvert que lorsque, au lieu d'utiliser des hydrures de métaux classiques (à base de Mg ou autres), on utilise un métal ou un hydrure de métal qui est soumis ou a été soumis à des déformations mécaniques intenses, tel qu'un hydrure de métal nanocristallin métastable, alors la réaction chimique, en particulier l'hydrolyse, aura lieu beaucoup plus facilement, à des vitesses beaucoup plus rapides et, la plupart du temps, jusqu'à achèvement.

Title: An indirect luminaire having a secondary source induced low brightness lens element
Inventor: HERST DOUGLAS J
IPC: F21V5/02
Filed: 1989-10-20
Abstract: An indirect lighting system having a generally visible light transmissive element, such as a prismatic lens element (31, 33) or a diffuser strip,  which modifies  the direction of  the  light incident thereon from a secondary light source,   The lighting system has a primary light source (13, 14) and structural means as in  a housing  (21)  for  positioning  the  primary  light  source proximate a reflective surface  (12)  which reflects light back toward the light transmissive element and which thereby acts as a secondary source of light for illuminating this element.  A light foil means such as vertical side reflector walls  (45,  47)  are disposed between the primary light source and light transmissive element for substantially blocking direct transmission of light to the latter from the former.   The light foil means, by keeping primary source light from directly striking the light transmissive element, forces the observable brightness in this element to be induced substantially entirely by the reflected light from the secondary source.

Title: Unknown response processing in a diagnostic expert system
Inventor: RYAN CHARLES P
IPC: G06F11/25
Filed: 1990-03-23
Abstract: ABSTRACT         A diagnostic expert system incorporating a cause-effect graph in which "yes", "no" and "unknown" are valid possible responses to a query.  Each node in the cause-effect graph is assigned a local decision factor based on its desirability for selection during best-first search of the cause-effect graph and a collapsed decision factor based on the average values of the local decision factors for all the node's daughter nodes.  For a current node under examination, a list of all its daughter nodes is obtained and examined to remove all daughter nodes that have been visited before in the current transition and all daughter nodes which have prerequisites that are not met.  Then, the daughter node with the largest local decision factor is selected, and its test function is executed.  If the user response is "yes", the chosen daughter node is made the current node, and a list of its daughter nodes is obtained to continue the process.  If the user response is "no", the daughter node is added to the closed list, and the process continues with the current node, its next eligible daughter node being selected.  If the user response is "unknown", the daughter node's collapsed decision factor is compared with the local decision factors for all the other daughter nodes of the current node which are not on the closed list and which have their prerequisites met.  If the collapsed decision factor is larger than all the local decision factors, the daughter node is made the current node to continue the process whereas, if the collapsed decision factor is not larger, then the daughter node with the largest local decision factor is selected, and its test function is executed to continue the process.

Patent CA-2041069-A1 (CA)
Title: Catheter retainer
Inventor: HOLLANDS KEITH G M
IPC: A61M25/02
Filed: 1991-04-23
Abstract: None of the catheter retainers presently commercially available are entirely satisfactory. Surgeons therefore still quite frequently stitch a catheter to the skin of the wearer. This is frequently done when it is desired to drain a wound and yet hold the wound largely closed. This procedure of course involves a risk of infection and may be painful for the patient.       Prior art catheter retainers are unsatisfactory for a number of reasons.   Firstly the retainer may be size dependent. In other words, for catheters of different diameter, a different catheter retainer device may be required. Another disadvantage is that known catheter retainers are often hard and rigid, and therefore uncomfortable to wear. Wearing them may promote lesions or maceration of the skin and so give rise to problems other than that for which the patient is in hospital. Another disadvantage of known catheter retainers is that they are hard to clean. Also, when used with catheters which are of a silicone rubber, a material commonly used for catheters, the catheter tubes are hard to lock in position relative to the retainer because of the slipperyness of the tube. As a result, patients can inadvertently pull catheters out. Yet another disadvantage of known catheter retainers is that the clamping pressure which most of them need to apply tends to collapse the catheter or the drainage tube. In consequence, the efficency of drainage is adversely affected.       The invented catheter retainer has a pad of medical grade adhesive capable of attachment to the body of a person who has to use a catheter. The pad carries a member to which is secured a cotton or synthetic fibre thread, or a thread of like material. In use the thread is wound around the catheter and fastened off by being attached to the member. The member is preferably slotted for this purpose.
