Title: Remote monitoring of grade crossing warning equipment
Inventor: BROWN AUGUSTUS HENRY
IPC: B61L29/30
Filed: 2002-12-19
Abstract: A system (40) and method for remotely monitoring the operating status of railroad grade crossing warning equipment. A sensor (46) generates a signal (48) responsive to the operation of a grade crossing annunciator (42). In one embodiment, the annunciator may be a bell or speaker horn (92) and the sensor may be an accelerometer (99) mechanically coupled to the bell. A wayside controller (52) uses the signal as input for developing information (70) indicative of the operating status of the annunciator. A communications link (74) transmits the information to a location remote from the grade crossing. A system controller (78) located at the remote location may diagnose the information to direct a maintenance center (82) and/or operations center (86) in response to an indication of degraded performance of the annunciator. The communications link may include the Internet and may be used for two-way communication between the remote location and the grade crossing location (22).
Patent CA-2416723-A1 (CA)
Inventor: PRINDLE GORDON E
IPC: A22C17/00
Filed: 2001-07-27
Abstract: The present invention provides a detectable heavy duty needle cannula (12) for use in hypodermic syringes and the like. Needle cannula (12) comprises a magnetizable or magnetized stainless steel alloy, which enables needle cannula (12) to be detectable in metal detectors that are commonly used in the meat processing industry to detect broken needle cannulas in the flesh of slaughtered animals. Needle cannula (12) further comprises a sidewall (17) that is thicker than the sidewalls of prior art needle cannulas. The thicker sidewall imparts to needle cannula (12) greater resistance to breakage during the process of injecting animal health products into an animal and greater detectability in a metal detector.

Title: System for fracturing wells using supplemental longer-burning propellants
Inventor: TIERNAN JOHN P
IPC: E21B43/263
Filed: 2003-01-22
Abstract: A system for fracturing wells uses a primary propellant charge to initially produce pressures within the well in excess of the maximum fracture extension pressure of the surrounding formation, but below that which would cause damage to the well. A supplemental propellant charge burns for a substantially longer period of time than the primary propellant charge, and thereby maintains pressures within the well in excess of the maximum fracture extension pressure for a significant period of time following completion of the primary propellant burn.

Patent CA-2424746-A1 (CA)
Inventor: NAKAI HIDEMI
IPC: B32B15/04
Filed: 2001-09-28
Abstract: A transparent laminate having low emissivity which has one or more dielectric layers such as a zinc oxide (ZnO) film and one or more metal layers such as a silver (Ag) film being laminated on one another, characterized in that at least one dielectric layer is divided in the direction of film thickness by at least one amorphous layer. The transparent laminate having low emissivity exhibits improved durability of the metal layer, since the formation of a zinc oxide film as a dielectric layer on an amorphous layer causes the collapse of the columnar crystal structure of zinc oxide and, as a result, not only the amorphous layer but also the dielectric layer act also as a barrier preventing the entry of moisture or a gas.

Title: Cathodic protection of steel in reinforced concrete with electroosmotic treatment
Inventor: LYUBLINSKI EFIM YA
IPC: C23F13/04
Filed: 2001-10-17
Abstract: Combining an electroosmosis direct current (EP) applied at less than 1mA/Mcm3 with an anode (8) placed adjacent an outer surface of reinforced concrete (1) soaked with a substantially neutral saline solution, effectively depletes corrosive anions in the concrete even when the direct current is in the range from 0.01 mA to less than 1mA and at a voltage less than 100 V. Further, using such electroosmotic treatment as a first treatment, and promptly following it with cathodic protection, it is found that current density of CP required for cathodic protection is unexpectedly reduced and when coupled with low installation and operational costs of the novel system, improvement in the efficiency of a conventional cathodic protection system is found to be by a factor of 3 to 30 times. Both processes may be operated together without one circuit interfering with the other.

Patent CA-2432102-A1 (CA)
Inventor: MERRITT TREVOR
IPC: B29L9/00
Filed: 2001-12-19
Abstract: This invention resides in an apparatus (10) and related method for rapidly curing thin film sol-gel coatings, particularly such coatings adhered to low melting temperature plastic substrates (16), whether rigid or flexible, without deforming the substrate. The curing is achieved using IR heating lamps (18) and dry or humid hot gas flow. This curing densifies the sol-gel coating and provides desired optical and mechanical properties. The use of IR lamps (18) and hot-gas nozzles (20), either singularly or in combination, produces a rapid cure by effectively heating the thin film coating layer. In this manner, a sufficiently high temperature can be attained in the film layer, to densify the sol-gel coating, but for a sufficiently short time duration to avoid melting or otherwise deforming the substrate. The sol-gel coatings can be cured two to three orders of magnitude faster than with conventional oven curing, leading to significant cost reductions and manufacturing efficiency.
Patent CA-2433083-A1 (CA)
Inventor: HARMAN MURRAY R
IPC: G02B6/42
Filed: 2003-06-20
Abstract: A positioning device suitable for accurately positioning objects such as optical fibers includes a first support, a movable support restrained for movement relative to the first support with one degree of freedom and carrying a holder for the object to be positioned, and an intermediate support which is connected to the first support by a pair of first spaced flexible elements of equal length and which is connected to the movable support by a pair of second spaced flexible elements, the second pair also being equal in length to each other. The first and second flexible elements are oppositely arranged and dimensioned so that arc-errors in the movement of the intermediate support caused by bending of the first flexible elements are substantially compensated by arc movements of the second flexible elements to produce a desired movement of the movable support, which may be rectilinear or angular movement about an axis. An actuator causes movement of the movable support with bending of all the flexible elements, and a control member connects the first support, the intermediate support and the movable support so that the degree of movement of the intermediate support is one half the movement of the movable support.

Abstract: A tablet system for prolonged floating in or on gastric fluid for releasing therein pharmaceutically active substances in an alternate succession of substance release and no-release periods is made up of a multilayered core placed in a cup-shaped envelope. The core is made up of release layers and n o- release layers devoid of pharmaceutically active substance, superposed in alternate succession. The cup-shaped envelope covers bottom and side surface s of the core while leaving exposed an upper surface of the core. The cup-shap ed envelope provides for buoyancy by being formed of a compression-sintered mixture comprising hydrophobic material and inert powdered filler. The hydrophobic material is composed of fatty and/or waxy material capable of being sintered by compression and whose bulk density is lower than gastric fluid density. The powdered filler has a loose powder density that is lower than gastric fluid density.

Abstract: An internally supported cable system control for a bicycle that does not interfere with the steering mechanism and does not require the structural integrity of the bicycle frame to be compromised. In the disclosed internal cable system, the control cables are routed through a passageway in the gooseneck and the bicycle frame to the mechanism or device that they are designed to control. The gooseneck design is unique in that it allows for an unobstructed passageway for the cables to travel into the steering tube and frame, while allowing for both sliding forward and rearward as well as raising and lowering, as desired by the bicycle rider. For aesthetic reasons, a casing may be added to cover the cabling between the control levers and the gooseneck.
