Patent CA-2209132-A1 (CA)
Title: Geophysical methods and apparatus for determining the hydraulic conductivity of porous materials
Inventor: ANDERSON DENNIS MICHAEL
IPC: G01V3/02
Filed: 1996-01-11
Abstract: The fundamental principle of the invention is based on applying geophysical concepts and techniques to measure the physical properties of porous mediums and then calculate the hydraulic conductivity of a test site. Development of geophysical methods and apparatus for determining the hydraulic conductivity of porous medium adapts three primary theories of applied geophysics. The invention determines the permeability by uniquely modifying the use of the Wenner Electrode Array (2, 3, 4, 5), then rearranging the Wyllie-Rose general expression to calculate the hydraulic conductivity of the porous material. All three of the geophysical technologies are uniquely adapted and combined into a single general geophysical-permeability equation. The invention measures hydraulic conductivity of a porous material with geophysical technology.

Patent CA-2212935-A1 (CA)
Title: Reciprocating piston type internal combustion engine with variable compression ratio
Inventor: LEITHINGER SIEGFRIED FRANZ
IPC: F02B75/04
Filed: 1996-02-28
Abstract: The compression ratio is variable in that the piston hub may be adjusted, since the connecting rod is mounted at the crankshaft side on an eccentric crank pin. The eccentric crank pin can be adjusted around its axis of rotation by control means while the engine is running. The control means include a toothed wheel that turns concentrically to the axis of rotation of the eccentric crank pin and is fixed thereto.      This toothed wheel acts as an external gear inside a larger diameter internal gear inside which it rolls. The internal gear is concentrically mounted around the axis of the crankshaft and its rotating position may be adjusted. The external gear turns exactly once upon itself every time it rolls round the internal gear.

A method of using the baffle inserts is disclosed in which the baffle inserts are inserted during preassembly of the heat exchanger prior to the brazing operation.
Patent CA-2215806-A1 (CA)
Title: Tool unit clamping apparatus having improved short-stroke locking mechanism
Inventor: ERICKSON ROBERT A
IPC: B23B29/04
Filed: 1996-02-07
Abstract: A short-stroke clamping apparatus for detachably connecting a tool unit to a tool supporter is provided of the type having a canister member which includes apertures for admitting spherical locking elements, and a lock rod that is reciprocally movable a stroke distance along an axis and which has cam portions for moving the spherical locking elements through the canister apertures into engagement with the tool unit. In the clamping apparatus, the canister member apertures are elongated along the stroke axis. This allows the spherical locking elements to move axially along the cam portions of the lock rod as well as radially, such that locking engagement can be achieved with a shorter axial stroke movement of the lock rod. The aperture walls may also be angled to allow even greater axial movement of the locking elements, which not only further shortens the lock rod stroke, but can increase the gripping force that the clamping apparatus applies to the tool unit. The shorter lock rod stroke in turn advantageously shortens the tool envelope, and increases both the rigidity and life of the spring package that withdraws the lock rod. The aperture walls may also be angled to improve the force of locking engagement between the locking elements and the tool unit.

Abstract: A data processing system (10) to enable the formulation of multi-party investments contracts is disclosed. The system comprises input means (13, 14) by which an ordering party can input contract data relating to at least one phenomenon, the phenomenon having a range of future outcomes and a future time of maturity. The contract data further includes a set of probabilities of occurrence for each outcome in the range and a consideration due to a counterparty at or after the time of maturity. One or more counterparties can input registering data including a set of probabilities of occurrence for each outcome in the range. The system (10) further includes a data processor (20) that is operable to price and match a contract from the contract data and the registering data. The pricing includes applying at least one template of entitlement as a function of outcome to each counterparty's set of probabilities to give one or more individual counterparty prices each equal to the ordering party's consideration, and further, applying the ordering party's set of probabilities to each template to derive an implied entitlement. The matching includes determining which counterparty will provide the best entitlement on maturity by comparing each implied entitlement with the consideration, and matching the contract with the counterparty having the template for the best comparison.
Patent CA-2225698-A1 (CA)
Inventor: MCINNES JAMES C
IPC: A61C17/22
Filed: 1996-06-19
Abstract: An electric toothbrush (10) with an adaptive load sensor (12) is disclosed.  The toothbrush of this invention includes a brushhead (16) that is vibrated by a drive assembly (18). The load sensor monitors the current drawn by the drive assembly to determine the mechanical load to which the toothbrush is exposed.  The load sensor assembly produces an adaptive threshold signal that represents the instantaneous maximum pressure load. If the sensed load voltage exceeds the adaptive threshold signal, the load sensor assembly deenergizes the drive assembly and generates an alarm signal so as to give the user a warning that the toothbrush has been excessively loaded.

Patent CA-2232381-A1 (CA)
Title: X-ray imaging apparatus and method using a flat amorphous silicon imaging panel
Inventor: GILBLOM DAVID L
IPC: G01T1/02
Filed: 1997-06-30
Abstract: An x-ray imaging apparatus receives an image-carrying x-ray beam (12) on a flat amorphous silicon imaging panel (20) with a light detector unit (40) disposed behind. The imaging panel is of a multilayered structure having sequentially a light-blocking layer (26) which is opaque to visible light but transmissive to x-rays, a converting layer of a phosphorescent material (98) for converting x-rays incident thereon into visible light, and a two-dimensional array of photosensitive elements (30) of an amorphous semiconductor material such as amorphous silicon, adapted to undergo a detectable change in electrical characteristic in response to impingement of light. The light detector unit (40) may be a simple light detector for receiving the light emitted from the converting layer and passed through regions between neighboring pairs of the array of photosensitive elements (30). Since the energy of light thus detected is directly proportional to the total light energy emitted from the converting layer, the output signal from such a light detector unit can be conveniently used for the exposure control of the imaging panel.

Title: Clamping device for detachably connecting two profiled parts
Inventor: ZUELLIG KURT
IPC: F16B2/04
Filed: 1996-11-26
Abstract: The invention concerns a clamping device for detachably connecting two profiled parts (1, 19). There can be inserted and secured in a first profiled part (1) an insert core (2) comprising an axially movable slide (7) with an end part having a projection (17, 18) which can be at least partially inserted into an opening in a second profiled part (19) in order to exert clamping pressure against a portion of the second profiled part (19), which portion partially closes the opening. The slide (7) is flat, and the insert core (2) comprises two inner grooves for axially guiding the slide (7). Rotatably guided in the insert core (2) is an eccentric (5). When the eccentric head (4) is rotated, the eccentric roller (22) presses against the inner wall (30) of a recess (12) in the slide (7) in order to move the latter into the insert core (2) into a position which enables the projection to exert the afore-mentioned clamping pressure.
