Patent CA-2198385-A1 (CA)
Inventor: MOUK ROBERT W
IPC: C22B43/00
Filed: 1995-09-12
Abstract: On décontamine des sols, comprenant du sable et des argiles contaminés par des déchets nucléaires et/ou des ions de métaux ou métalloïdes non radioactifs dangereux, en les traitant avec de l'ammoniac anhydre liquide seul ou en combinaison avec des électrons solvatés. Les procédés décrits consistent à éliminer les ions de métaux ou métalloïdes dangereux par mélange avec des solutions ammoniacales, afin d'obtenir un produit contenant le liquide ammoniacal avec des complexes de coordination. Ces procédés consistent également à concentrer les substances contaminantes, telles que le plutonium, l'uranium et le thorium, par exemple, contenues dans les fines du sol et des argiles, de manière à obtenir des sols suffisamment libres de substances contaminantes pour permettre une récupération. Ce système présente un avantage économique par rapport aux systèmes aqueux, dès lors que l'ammoniac peut être récupéré et recyclé. La concentration des déchets nucléaires et non nucléaires contenus dans les fines du sol permet de réduire considérablement l'espace occupé normalement par le stockage du sol non traité, de même que les coûts de manutention.

Patent CA-2205979-A1 (CA)
Inventor: CALDWELL HOLLEY G
IPC: H04M1/2749
Filed: 1997-05-23
Abstract: A system and method in which the user is provided the option of automatic recall of selected numbers which have been previously called.   The computer based system which  is  controlled  by  operation  of  a  conventional push-button telephone  repeatedly  places  selected  calls and plays a selected prerecorded message whenever a call is  answered.   Processors  provide  the  capability  of recognizing the results of each call as to whether the call has reached a number which is busy or is answered, and also as to whether the call is answered by a person or by an answering machine.   In response to recognition signals,  the  system,  at  the  appropriate  time,  plays a selected  message.   When a  call  has  been  successfully completed  the  called  number  will  be  removed  from  a numbers  queue within  the  system,  and  the  system will record  the  time  and  date of  the completion.   Numbers remaining   in   the   queue  will   be   recalled   until successfully  completed.    The  number  of  unsuccessful recalls,  and the time at which each was made,  is also recorded by the system.   The system is programmable to make calls during selected time periods.  A display panel provides information relating to operation of the system.

Title: Moulding for window of vehicle
Inventor: SAKAMOTO SATOSHI
IPC: B60J1/02
Filed: 1997-07-15
Abstract: To prevent abnormal sounds made by the vibration of the tip of a seal lip of a moulding for a window of a vehicle which sounds are created when air is sucked out from an inner cavity by the difference in pressure between the inside and the outside of the seal lip when the vehicle operates at high speed, a seal lip body 4a extends in the direction of a vehicle body panel P from the leg of the moulding 1 for a window and a folded-back lip 4b is continuously integrally formed such that it is folded back in the opposite inward direction from the tip of the seal lip body 4a into the cavity 5 between itself and the vehicle body panel P and extends along the vehicle body panel P. When the vehicle is operated at high speed, even if the seal lip 4a is moved up by the difference in pressure between the inside and the outside of the seal lip body 4a, the folded-back lip 4b remains pressed against the vehicle body panel P and thus prevents the leakage of air from the cavity 5. Therefore, it can prevent the abnormal sounds which occur when the air leaks out.

Patent CA-2217374-A1 (CA)
Title: Extensional flow mixer
Inventor: LUCIANI ANDRE
IPC: B01F7/00
Filed: 1997-09-29
Abstract: An extensional flow mixer especially for viscous liquids has a housing with an end inlet connectable to a pressurized source of the liquids, and an outlet leading from the housing cavity at an opposite end of the housing. A mandrel is located in the cavity,  and first and second die members are held respectively at the outlet end of the cavity and at a facing end of the mandrel. Both die members have annular, concentric protrusions  with  symmetrically  opposed  inner  edges,  the protrusions dividing the space between the die members into a series of annular chambers separated by annular slits.  The mandrel sides have spiral grooves forming spiral passageways with the housing wall,  and which are connected by radial passageways to the inlet. The passageways allow liquid flowing from the inlet to be distributed evenly around the edges of the die members, passing between these to the outlet.
