Title: Filtration system
Inventor: ZALOUM RONALD
IPC: B01D61/18
Filed: 1993-12-21
Abstract: This filtration system involves the use of highly permeable  synthetic  materials  (membranes)  to allow water from a flocculent suspension such as from an activated sludge or a physical/chemical treatment system to permeate through while retaining the solid fraction on the outer side of the membrane.  The mem-brane  is  wrapped  around  a  tube  made  of  resistant material or equivalent into which large openings are made.  The entire assembly is immersed in the reactor vessel.    Air  backwash  is  applied  periodically  to restore flux rates.  The filtration process is continu-ous without downtime due to backwashing.  Flux rates as high as 500 l/m2/hr have been obtained consistently for the treatment of effluents from a cheese factory with a biomass having a concentration of 2.5 g/l.   Effluent turbidity was less than 0.4 NTU.

The projecting element in the projecting position then depends from the base of the nacelle.
Patent CA-2115139-A1 (CA)
Inventor: GOODMAN WILLIAM A
IPC: F02B53/00
Filed: 1991-08-06
Abstract: 2115139 9303257 PCTABS00019 A circular rotary engine comprises a housing having spaced concentric cylindrical walls (23, 26) defining an annulus therebetween with intake (28-I) and exhaust ports (27-E) through the sides of the walls and a cylindrical rotary piston ring (10) having multiple symmetrically undulating surfaces (c, d) on both ends and coaxial interior (20) and exterior (19) gears for shaft drive which rotates within the annulus while reciprocating between end ring members (9, 11) positioned within the annulus and secured at each end of the interior and exterior walls. The end rings (9, 11) have opposite facing undulating frontal surfaces (a, b) symmetrical with the undulating frontal surface (c, d) of the rotary piston (10) such that the piston ring surfaces cooperate with the end ring surfaces to alternately create a volume area and displace the volume area in some portion during rotation, thus alternately opening a series of chambers (5, 6, 8) on one end of the rotary piston (10) while displacing chambers (1, 2, 4) on the opposite end with the reciprocating movement during axial rotation of the rotary piston responding in motion against the symmetric frontal surfaces of the end rings. This motion is accomplished while maintaining frontal surface contact (12, 13, 14, 15) at all times, without restriction to rotation whereby frontal surface seal contact is maintained during axial reciprocation and rotary movement. All components are coaxial thus providing the rotary piston with controlled circular axial rotation within the annulus with the end ring members controlling reciprocation.

Patent CA-2134013-A1 (CA)
Inventor: KUTTEN SHAY
IPC: H04J13/00
Filed: 1994-10-21
Abstract: In a communications system, a method is described allowing two users having established a communication session identified by a unique session freshness proof, to transmit and validate a new value of a variable by using an exchange certificate   which combines the following elements : the new value of the variable, a common  secret  key  known  by both  users,  an  exchange  counter representative of the number of values of said variable transmitted between the two users during the current communication session and a   session   freshness   proof.   Protection  against   potential eavesdroppers   and   intruders   is   provided   by   combining cryptographically the elements of the exchange certificate. Further protection is obtained by interrupting the current communication session and opening a new one characterized by a new unique session freshness proof when the exchange counter reaches its maximum value; thus avoiding the risk that the same value of the session freshness keeps being used when the exchange counter is reset to its initial value. Consequently a given pair of values of the session freshness proof and of the exchange counter will never be used more than one time,  making eavesdropping and,  replaying attacks from intruders more difficult. Preferably, the method used for  opening  a  new  communication  session  uses  already  known authentication methods based on the common secret key.
Patent CA-2134019-A1 (CA)
Inventor: ACOCELLA JOHN
IPC: H01L23/488
Filed: 1994-10-21
Abstract: High melting temperature Pb/Sn 95/5 solder balls (18) are connected to copper pads on the bottom of a ceramic chip carrier substrate (10) by low melting temperature eutectic Pb/Sn solder. The connection is made by quick reflow to prevent dissolving Pb into the eutectic solder and raising its melting temperature. Then the module is placed on a fiberglass-epoxy circuit board with the solder balls on eutectic Pb/Sn solder bumps on copper pads of the board. The structure is reflowed to simultaneously melt the solder on both sides of the balls to allow each ball to center between the carrier pad and circuit board pad to form a more symmetric joint. This process results in structure that are more reliable under high temperature cycling. Also, to further improve reliability, the balls are made as large as the I/O spacing allows without bridging beam on balls; the two pads are about the same size with more solder on the smaller pad; the pads are at least 75% of the ball diameter; and the eutectic joints are made as large as possible without bridging between pads. For reliability at even higher temperature cycles or larger substrate sizes columns are used instead of balls.

Title: Method for treating cardiovascular disease through adjunctive photodynamic therapy
Inventor: NARCISO HUGH L JR
IPC: A61K31/555
Filed: 1993-07-12
Abstract: Photodynamic Therapy (PDT) is used as an adjunctive or stand alone procedure for the treatment of cardiovascular dis-ease. When used as an adjunctive therapy to Percutaneous Transluminal Coronary Angioplasty, laser angioplasty, atherectomy, stenting, or any other interventional or surgical procedure, it has been found that the treatment timing is critical to the success of the combined therapies. A photosensitizer is administered prior to the surgical or interventional procedure and then readminis-tered after the procedure to maintain the photosensitizer concentration level in the atheromatous plaque and smooth muscle cells in the vicinity of the lesion for a period of about 5-18 days, the period in which cell proliferation can occur. The photosensitizer inhibits smooth muscle cell proliferation and, thus, minimizes or eliminates the possibility of re-stenosis. The photosensitizer is then illuminated at the end of this period, thereby lysing the atheromatous plaque and smooth muscles. The photosensitizer inhi-bits atheromatic smooth muscle cell proliferation.
