Patent CA-2171787-A1 (CA)
Title: Protective intraluminal sheath
Inventor: ANDERSON SCOTT C
IPC: A61F2/06
Filed: 1996-03-14
Abstract: A sheath holds a device against a balloon catheter for delivery in the lumen of a patient. The device can be a stent and graft combination. The stent is kept properly centered over the balloon catheter by the sheath as the graft is placed in a blood vessel. The smooth outer surface of the sheath protects the vessel wall from the rough surface of the stent. A notch is formed in the end of the sheath where the free end of a strand of thread protrudes from the sheath. The sheath is removed from the graft by pulling on the free end of the strand otherwise located distally from the outer surface of the sheath. The strand cuts through and splits open the sheath as a result of the force applied on the free end of the strand. The other end of the strand is attached to a reinforced collar at the other end of the sheath. The strand does not cut through the collar. After reaching the collar, the proximal force applied on the strand now pulls the split sheath from the stent-and-graft combination without disturbing the placement of the stent over the balloon delivery catheter.

Title: Process of treating produced water with ozone
Inventor: MORROW LAWRENCE ROBERT
IPC: C02F1/78
Filed: 1997-04-21
Abstract: Ozonolysis is an effective process for improving the quality of produced water. A process for reducing the concentration of water soluble organic materials dissolved in produced water consists of introducing into the produced water a sufficient amount of gaseous ozone by use of a means for maximizing the collision frequency of ozone gas and the produced water. The temperature of the produced water is between from about 80° to about 180° F. The process renders a water effluent with markedly reduced oil and grease content. The water effluent can be used on land as a drinking or irrigation water supply source and may be safely discharged into navigable waters.
Patent CA-2206710-A1 (CA)
Title: Regeneration of dithiophosphorus acid metal extractants
Inventor: KRAUSE EBERHARD
IPC: F28F21/08
Filed: 1997-06-02
Abstract: The invention provides a method of regenerating dithiophosphorus extractants such as dithiophosphoric acids, dithiophosphonic acids and dithiophosphinic acids from their sulfur-sulfur bonded oxidation products contained in an organic solution. The process generates active hydrogen for regenerating the spent dithiophosphorus. extractants. Advantageously, this active hydrogen originates either from introducing a reactive metal into a liquid mixture containing the organic solution and an acidic aqueous solution to form nascent hydrogen or from using hydrogen gas in the presence of a catalyst in the organic solution. The active hydrogen generated in the process breaks thesulfur-sulfur bonds of the dithiophosphorus molecules to form the corresponding dithiophosphorus acids.

Patent CA-2221462-A1 (CA)
Inventor: NAITO YUSHI
IPC: H04L47/43
Filed: 1997-11-17
Abstract: In establishing an audio one link connection wherein an audio signal is not encoded/decoded in a relay station,  loud noises may be produced if the states of two audio tandem relay devices which make  a pair during relay are changed from a normal  connection  state  to  a  relay  connection  state  at different times.  In order to solve this problem, comfort noise generators  are provided.   In detail,  when a  first  pattern signal is detected while a relay call is connected via a relay exchange, switches are switched to be connected at a contact point 1, and a switch is at a contact point 2.  Upon detection of a second pattern signal, the switches are connected at the contact points  2,  while  the  switches  are  connected at  the contact points  2.   With this  arrangement,  outputs  from the comfort noise generators are selected and outputted during a period from first pattern signal detection to second pattern signal detection,  during which the states of the two devices of a pair are different.   As a result,  occurrence of  loud noises is prevented.
