Title: Therapeutic applications of chimeric organogenesis
Inventor: AUGER FRANCOIS A
IPC: A61L27/60
Filed: 1993-12-21
Abstract: A process for culturing and generating a chimeric cell culture, in particular chimeric epithelium, is disclosed. The chimeric epithelium oan be used to treat skin trauma such as burn victims. Autologous epithelial grafts have been used on burn patients although this requires that the patient's cells are cultured and expanded in vitro which generally takes four to five weeks.  The chimeric epithelium of the present invention is composed of cells that are both autologous and allogeneic to the host. Therefore, the allogeneic cells can be maintained in a cell bank and co--cultured with autologous host cells when needed.  This significantly reduces the time required (by up to 50 %) for autologous cell expansion and culture prior to grafting. Furthermore, it has been demonstrated that the allogeneic cells are passively eliminated from the graft without rejection of the total graft.

Title: Non-linear chain belt type conveyor
Inventor: PARSLOW HAROLD W JR
IPC: B65G43/08
Filed: 1995-07-27
Abstract: A compact chain belt-type conveyor for conveying articles along a non-linear path through an industrial washer and drier.  The chain belt-type conveyor provides an article  sensing  means  wherein  the  sensing  means is responsive to the presence of an article at a predetermined station  along  a  predetermined  non-linear  path.    A signalling means, responsive to the sensing means, signals a driving means to stop the conveyor when an article is present at the predetermined station for a predetermined amount of time and starts when an article is absent from the predetermined station.  The signalling means ensures that each article will only be placed through one washing and drying cycle since a washed article must be removed from the predetermined station of the conveyor before the driving means will continue to drive the conveyor.   An article holding means may  be  provided  to  secure  the articles along the conveyor and provide proper orientation of the articles through the washing and drying process.  A chain mesh construction conveyor may also be utilized to support and carry articles without the use of the article holding means.  In the preferred embodiment, the non-linear shape of the conveyor is substantially u-shaped so that articles  can be  loaded and unloaded to and  from the conveyor by either a single operator or a single automated mechanism.   The present invention also provides for a programmable robotic arm that responds to the presence of an article at the predetermined station.

Patent CA-2163708-A1 (CA)
Title: Integrated dual-function catheter system for balloon angioplasty and stent delivery
Inventor: FISCHELL ROBERT E
IPC: A61F2/06
Filed: 1995-11-24
Abstract: An integrated catheter system utilizes a balloon angioplasty catheter placed through a central passageway of a stent delivery catheter to enable balloon angioplasty and stent delivery to be accomplished with a single device. The integrated catheter system is able to perform dilatation of an arterial stenosis, placement of the stent at the site of the stenosis and then the angioplasty catheter balloon can be used to further embed the stent into the arterial wall. Balloon angioplasty, stent placement and stent embedding into the arterial wall are all accomplished while the catheter's angioplasty balloon remains situated at the site of the stenosis. A conically-shaped distal portion of the stent delivery catheter allows stent placement over the deflated balloon after balloon angioplasty even when intimal dissection causes an intimal flap to be pushed inwardly against the deflated balloon. A proximal portion of the integrated catheter system employs longitudinal motion constraining spacers to prevent the stent from being inadvertently positioned beyond the distal end of the balloon. The balloon of the balloon angioplasty catheter can be readily advanced through tortuous coronary arteries because the distal end of the stent delivery catheter can be placed back by 0.5 to 20 cm from the balloon's proximal end during insertion. Thus, the stiffness of the stent and the stent delivery catheter do not add stiffness to the distal portion of the balloon angioplasty catheter, which stiffness can prevent catheter advancement through such tortuous vessels.

IPC: G01N29/11
Filed: 1995-06-01
Abstract: A method is provided for detecting degraded water main pipes by monitoring sonic and ultrasonic waves (110, 112, 114) and observing the characteristics of those waves. Water main pipes (30) have coiled tensioned steel wire (42) which holds the surrounding concrete (32) in compression. When corroded by water, the steel wire (73) ruptures, relieving compression in the concrete adjacent the rupture. The waves traversing the concrete of pipes have different characteristics for pipes in poor condition as compared to pipes in good condition. The sound waves in pipe in poor condition travel slower with shear waves having less amplitude and reflections occuring at later times.  Frequency domain characteristics of pipes in poor condition differ from the frequency domain characteristics of pipes in good condition. For pipes in poor condition, resonance occurs at lower frequencies and a drum head effect is apparent.
