Title: Two-phase distributor system for downflow reactors
Inventor: MULDOWNEY GREGORY PATRICK
IPC: C10L1/00
Filed: 1995-06-14
Abstract: A distributor system (18, 36) for uniformly directing vapor and liquid across the surface of a fixed bed (42) of solids in a downflow reactor (14). A first array of open-ended downpipes (33) has a plurality of vertically spaced elevations of holes (39, 40) above the level of a distributor tray (18). A second array of the downpipes (34) has at least one elevation of holes (41) but no elevation of holes as the same height as the lowermost elevations of holes (40) in the first array (33). The absence of holes causes the liquid flow rate through the distributor tray (18) at a given height to be reduced when that liquid height falls below the elevation of holes (39) second from the bottom in the first array (33).

Title: Rear suspension system for a land vehicle
Inventor: BOIVIN DENIS
IPC: B62D55/108
Filed: 1996-11-22
Abstract: A suspension assembly for mounting an endless track to a chassis of a snowmobile, the suspension assembly having a pair of pivoting arms centrally mounted to the slide members, or rails, and a weight transfer dynamic compensator capable of compensating for the weight transfer of the snowmobile when the track is pulling on the chassis. The weight transfer dynamic compensator prevents the chassis from rotating excessively with respect to the slide rails during rapid acceleration. Such a rotation of the chassis is detrimental to rider comfort and stability. The suspension assembly is coupled such the rails remain somewhat parallel to the chassis when encountering a bump at either the front of the rails or at the rear of the rails, also enhancing rider comfort and stability. The suspension assembly is coupled by virtue of a limited-translation slide bar at the rear of the suspension assembly and a tension-only member, or pulling belt, located at the front of the suspension assembly. The suspersion assembly having the weight transfer dynamic compensator improves the cornering of the snowmobile by ensuring that there is ample weight on the front skis, especially when accelerating out of a turn.

Title: Assay and reagent kit for the quantitative in vitro determination in biological specimens of the activity of proteins causing multi-drug resistance in tumors
Inventor: SARKADI BALAZS
IPC: G01N33/50
Filed: 1995-08-31
Abstract: Disclosed herein are a diagnostic assay method and reagent kits for the quantitative in vitro determination of the activity in biological specimens of MDR proteins causing multi-drug resistance in tumors. The method of the invention is based on the measurement of the accumulation rate of a compound within the cells of the specimen (advantageously by fluorescence measurement) which compound is not a good substrate of the MDR protein present in the sample, not cell permeable and is being formed within the cells, by enzymes generally present in the cells, from a compound which is a good substrate of said MDR protein, cell permeable and is added to the specimen in vitro. Based on the method of the invention, it is possible to calculate an MDR activity factor (MAF) value that is, within the diagnostically relevant range, characteristic of the MDR activity, i.e. to the multi-drug resistance level of the specimen.

Patent CA-2207537-A1 (CA)
Inventor: HONES WILLIAM G
IPC: H02N15/00
Filed: 1997-06-12
Abstract: An electromagnetic drive apparatus and method are operative to rotate a magnetically levitated object for an indefinite period of time. The object, such as a spinning magnetic top with a spindle, is levitated over a base magnet and a horizontal component of a pulsed magnetic field is applied at the region of the spinning magnetic top to maintain the top spinning and levitating indefinitely. The pulsed magnetic field is generated by applying a pulsed dc voltage or an ac current to a coil situated in proximity to the top. The coil may have a cylindrical or oblong shape and a core may be provided in the coil. Levitation stability and duration are improved by positioning a loosely fitting washer on the spindle of the spinning magnet so as to permit relative rotation therebetween during application of the pulsed magnetic field.

Title: Method of operating and cleaning a star screen system
Inventor: HOULE ERIC
IPC: B07B1/50
Filed: 1997-08-27
Abstract: A method of operating and self-cleaning a star screen system. Star screen systems are usually made of several rotatable shafts disposed in parallel and each having a plurality of stars mounted on their axis. A chain drive allows to rotate the shafts simultaneously. The first step of the method consists of supplying material to be screened on the surface of the screen and rotating the shafts at a screening rotation speed. The supplying of material is then stopped. An optional step of operating the screen at the screening rotation speed may then be performed, to remove the remaining material to be screened from the screening surface. The next step consists of increasing the rotation speed to a value sufficient to dislodge material clogging the stars from the system by centrifugal ejection. This allows for self-cleaning of the system that is efficient and does not require the use of brushes or other cleaning tools.

Title: Method of preventing anode abrasion during electrocoagulation printing
Inventor: LEPINE NORMAND
IPC: C09D11/52
Filed: 1997-08-29
Abstract: An electrocoagulation printing method comprises the steps of  (a) providing a positive electrolytically inert electrode having a continuous passivated surface moving   at   substantially   constant   speed   along   a predetermined path,  the passivated  surface  defining  a positive  electrode  active  surface;   (b) coating  the positive  electrode  active  surface  with  an  olefinic substance  and  silica  to  form  on  the  surface micro-droplets  of  olefinic  substance  containing the  silica; (c) forming  on  the  olefin  and  silica-coated  positive electrode active surface a plurality of dots of colored, coagulated colloid representative of a desired image, by electrocoagulation  of an  electrolytically  coagulable colloid present  in  an  electrocoagulation printing  ink comprising a liquid colloidal dispersion containing the electrolytically coagulable colloid, a dispersing medium, a  soluble  electrolyte  and  a  coloring  agent;   and (d) bringing a substrate into contact with the olefin and silica-coated positive electrode active surface to cause transfer of the dots of colored, coagulated colloid from the surface onto the substrate and thereby imprint the substrate with the image. The use in step (b) of silica prevents abrasion and pitting of the positive electrode, without substantially affecting passivation.  The use of silica  also  prevents  the  formation  of  undesirable background on the printed image in step (d).

Title: Syringe barrel for lyophilization, reconstitution and administration
Inventor: GRABENKORT RICHARD W
IPC: A61M5/315
Filed: 1996-03-27
Abstract: The syringe system of the present invention includes a first or primary syringe barrel having a substantially closed end defining a delivery passage and an opposite open end. A removable closure seals the delivery passage of the first syringe barrel so as to define a container for containing a medical solution. A plurality of longitudinal channels are positioned on the inner surface of an enlarged diameter venting portion of the syringe barrel at the open end. A reciprocable stopper is provided for sealing the open end of the barrel so that the reciprocable stopper has a first position abutting the channels of the inner surface of the barrel so as to allow the medical solution to be lyophilized through the channels. The reciprocable stopper can then be longitudinally moved to a second position in the barrel in the direction of the delivery passage and beyond the channels to seal the lyophilized drug within the barrel. The reciprocable stopper preferably also further includes means for fluid communication of a liquid diluent from an associated diluent syringe through the reciprocable stopper from the direction of the open end of the barrel. Various configurations of fluid communication means effecting transfer of the diluent from the diluent syringe through the reciprocable stopper in the primary syringe barrel include connection by a sharp cannula through a resealable elastomeric reciprocable stopper, connection by a blunt cannula through a prepierced elastomeric reciprocable stopper, and connection with a one-way valve mechanism through the reciprocable stopper in conjunction with a connector on the diluent syringe or on a sterility maintenance sleeve between the diluent syringe and reciprocable stopper.
