Patent CA-2470290-A1 (CA)
Inventor: LACATUS TIBERIU
IPC: A47B81/00
Filed: 2004-06-08
Abstract: A clamping cartridge is provided which comprises a plurality of clamping mechanisms spaced apart on a frame or chassis. The clamping mechanisms are generally oriented perpendicular to their direction of spacing. The clamping mechanisms are of the type which comprise a pair of relatively movable jaws which are normally biased towards one another such that they resist opening and which return to a closed or substantially closed condition in the absence of external forces. An actuator operable in association with the clamping mechanisms serves to open and close the jaws of the clamping mechanisms in unison. The actuator includes a series of rotatable tapered cylindrical cam wheels disposed on a rotatable cam shaft to ultimately effect opening and closing of the clamps, which cam wheels are disposed generally within the clamps. By providing apertures or slots in the jaws of the clamps to accommodate the cam shaft, a considerable reduction in the height of the cartridge can be realized. The cam shaft is rotatably supported in bearings and a detachable handle is provided with which the shaft can be rotated. While the clamps are closeable in unison, they are individually self-adjusting so the extent of closure for each clamp is dependent on the thickness or presence of an inserted article. The clamping cartridges are useful in a variety of applications requiring clamping of one or more articles in a side-by-side relationship. One such application is a transportation/storage rack which includes a plurality of aligned horizontal and vertical clamping cartridges for clamping the edges of glass panels.

Title: Multiplexed analysis for determining a serodiagnosis of viral infection
Inventor: JOHNSON ALLISON JANE
IPC: G01N33/569
Filed: 2005-01-27
Abstract: Clinical samples can be analyzed using microparticles as a platform to determine the serodiagnosis of a viral infection from two candidate viral infections of the same viral group in a clinical sample. Various techniques can be used to determine serodiagnosis of viral infections; however, detection of a viral infection from two candidate viral infections of the same viral group in a clinical sample represents a significant advance. For example, serodiagnosis of a viral infection from two candidate viruses of the same viral group can be determined via a pooled population of subsets of microparticles, with the particles in the pooled population having a bound viral group-reactive antibody and the particles in each subset having at least one characteristic classification parameter that distinguishes one subset from those of another subset. Viral antigens of antibodies of interest in the same viral-class as the viral group-reactive antibody can be bound to the viral group-reactive antibody on the microparticles, and subsequently exposed to a clinical sample.  Viral antibodies in the clinical sample can bind with the antigens and a labeled reactant can be used to label the viral antibodies bound to the antigens. Multiplexed flow analysis and computer-implemented methods of analyzing the data produced from flow analysis can then be used to determine the presence or absence of antibodies of interest in the clinical sample, thereby diagnosing a viral infection from two candidate viral infections in a single assay.

Title: Monitoring and diagnosis of gastric emptying and gastroparesis
Inventor: EHRENPREIS ELI D
IPC: A61K49/00
Filed: 2003-09-12
Abstract: The invention relates to methods and compositions for measuring the rate of gastric emptying in animals, including humans. The methods of the invention measure the rate of stomach emptying by administration of a marker agent in a delayed-release formulation or food vehicle and blood or serum levels of the market agent are monitored over time. The blood or serum levels of a marker agent reflect the gastric emptying rate. Incorporating such agents in foods also delays the absorption of such agents and serves as a measure of digesti on and gastric emptying. These methods may be used to screen for drugs, herbal substances and other compounds that modulate gastric emptying, such as by increasing prokinetic activity of the gastrointestinal tract.

IPC: B03B9/02
Filed: 2005-03-16
Abstract: In a slurry preparation process for preparing uncrushed oil-sand ore to become suitable for subsequent slurry transportation, a step-wise series of process steps comprising receiving the uncrushed ore and water into a mixing hopper to create a mixture of ore and water; discharging the mixture onto a screen deck to separate oversize and undersize fractions; allowing the undersize fraction to discharge into a slurry preparation vessel; discharging the oversize fraction to a self-clearing crusher which comprises a receiving hopper and a driven crushing roll working in conjunction with an endless crushing conveyor chain, each driven by a reversible drive means. Forward motion of the crushing conveyor forcibly conveys the ore into a gap space set between the crushing roll and the crushing conveyor and crushed ore is discharged into the slurry preparation vessel. In the case of an uncrushable object entering the crusher gap and being detected by high load on the crushing roll drive or the crushing conveyor drive, the endless crushing conveyor is motivated in a reverse direction to discard the uncrushable object to a rejects pile outside of the slurry preparation vessel.
