Patent CA-2173339-A1 (CA)
Title: Data representation and access method
Inventor: MICHIE DAVID CHARLES
IPC: G09G5/393
Filed: 1995-08-25
Abstract: A method of representing and accessing an array of data is disclosed. Preferably, the array of data is an image. This involves determining a series of subsamples (21 to 28) of the array in which the subsamples (21 to 28) are of increasing granularity. The collection of the series of subsamples (21 to 28) substantially covers the whole of the data array. The series of subsamples (21 to 28) are then stored in order of granularity from coarsest to finest granularity. Thus, in reading out the stored data, only the corresponding subsamples (21 to 28) need be read out.

Patent CA-2184299-A1 (CA)
Inventor: QUINLAN DANIEL A
IPC: F04D29/66
Filed: 1996-08-28
Abstract: An air moving device such as an axial cooling fan comprises a rotatable shaft assembly and a plurality of fan blades coupled to the rotatable shaft assembly, each of the fan blades having a trailing edge when the rotatable shaft assembly is rotated in a given direction. In accordance with one illustrative embodiment of the invention, at least one of the fan blades has a sound reducing material attached thereto alongside the trailing edge thereof. The sound reducing material reduces aeroacoustic noise by reducing the aerodynamic effect that occurs when turbulence produced by the pressure differential between the two sides of one blade comes into contact either with the trailing edge of the given blade which created it, or, more significantly, with the following blade, at or near that blade's trailing edge. In various embodiments the sound reducing material may comprise felt, loops from a hook-and-loop-type fastener such as that sold under the "Velcro" trademark, or a small piece of fiberglass, cotton or wool batting. In one illustrative embodiment, the sound reducing material is advantageously attached to the fan blade on the high pressure side thereof.

Title: Saliva assay method and device
Inventor: THIEME THOMAS R
IPC: G01N33/558
Filed: 1995-03-29
Abstract: An improved method for determining the presence of an analyte in an oral fluid sample. In the method, a reaction mixture is produced containing at least a portion of the collected sample and a chromogenic substrate effective to produce a colored product upon reaction with amylase present in the sample. After a selected reaction time, the reaction medium is inspected to determine the level of colored product produced in the medium within the selected reaction time. Production of colored product above a preselected threshold level within the selected reaction time indicates that an effective volume of undiluted saliva sample has been collected sufficient to allow detection of the analyte. The invention also includes a device for use in the method.

Patent CA-2202835-A1 (CA)
Title: Retractable container stop and guide assembly for railroad freight cars
Inventor: BIS TOMASZ
IPC: B61D45/00
Filed: 1997-04-16
Abstract: There is provided an improvement for a railroad freight car for transporting containers. The car is of the type having spaced apart side structures, opposed end structures and a floor structure, all of which together define a well for receiving a plurality of containers. The well has a longitudinal direction substantially aligned with the direction of travel of the car and a transverse direction substantially normal thereto. The floor structure of the car has a container support within the well which provides a container support surface. The improvement comprises a container stop provided with the container support, the container stop having an extended position and a retracted position. The container stop is biased to the extended position by a biasing component. The extended position is defined by the container stop extending upwardly from the container support surface to present two stop surfaces within the well. The stop surfaces arrest the longitudinal translation of two of the containers when same are respectively located longitudinally on each side of the container stop and are respectively seated on the container support surface. The retracted position is defined by the container stop being retracted with respect to the container support surface when a container is placed onto the container stop, such that the stop surfaces are not presented within the well. The improvement also comprises a container guide associated with the container stop. The container guide is provided in one of the side structures, and includes a deflector which extends within the well in the transverse direction. The deflector longitudinally guides a container within the well as the container is being placed therein. The deflector is dimensioned and positioned with respect to the container stop so as to prevent both of two containers from seating onto the container stop together when each of the two containers is placed in succession within the well of the car.
