Patent CA-2314341-A1 (CA)
Title: Method and apparatus for removing obstructions in mines
Inventor: MICKE BRIAN P
IPC: F42B12/20
Filed: 1998-10-14
Abstract: The present invention is directed to a system for fragmenting rock obstacles and obstructions in mines. The system uses a projectile having a flat or concave nose and a detonating device that has a safety pin to prevent a striker from prematurely igniting the primer during handling of the projectile. The primer is designed to initiate a detonator which detonates an explosive charge upon impact of the projectile with the target rock. The system can include transmitters and receivers and counters to provide remote operation of projectile launch, prearming, arming and/or detonation.

Patent CA-2319891-A1 (CA)
Title: Slickline fluid identification tool
Inventor: MENAND PASCAL
IPC: E21B47/10
Filed: 2000-09-19
Abstract: Initially, signals relating to well bore fluids that are generated from sensors in presently available down-hole logging tools are analyzed and/or interpret ed by an electronic circuit in a well logging tool. The interpretation of these signals can be direct, differential, or summation measurements from the sensors. The signal interpretations can be qualitative or quantitative, depending on how the too l is set up or programmed of the electronic circuit. When gas/oil, gas/water, or oil/water contacts are made in the well bore, the circuit will send a signal to a set of electromagnets or a drag mechanism that will momentarily grab the walls of t he pipe. This will create a line tension spike on the load cell/weight indicato r on the surface, and a well log can be generated to show where these line tension spikes occur, thus indicating the depth of various fluids in the well bore. The electronic circuit in the well logging tool may be programmed utilizing software and or firmware to determine specific fluids in a well bore. The programming criter ia may be to look only for gas/oil, gas/water, or oil/water contacts, or to look specifically for a combination of these various fluid levels in a well bore. If multiple fluid level indications are desired, the circuit will send signals to the electromagnets to engage and remain engaged for longer periods of time for each type of fluid level. Also, various fluid levels can be distinguished by having electromagnets tur n on several times after the fluid level is encountered.
Patent CA-2321079-A1 (CA)
Inventor: KAWABATA SHUNJI
IPC: E01F9/559
Filed: 1999-12-16
Abstract: An embedded-type light (1) has a base (3) of a bottomed cylinder embedded in a PC pavement (2) and a light body (5) supported at the top of the base (3) and emitting light outside the pavement surface.  Projections (6) are provided on the outer surface of the base (3) so as to bear the load exerted downward on the light body (5) by the PC pavement (2) around the base (3). Thus, the load does not concentrate on the lower portion of the base (3). To alleviate the lack of stress in the PC  pavement (2) around the lower portion of the base (3), a cushioning material (7) is provided around the lower edge of the base (3). As a result, the decrease in strength of the PC pavement (2) around the lower portion of the base (3) is suppressed. Therefore the PC pavement around the lower portion of the base is prevented from turning brittle and a hollow in the PC pavement is prevented even if a very heavy load such as an airplane is exerted.

Abstract: A tissue-protective device (16, 18, 20, 60, 66, 76, 86, 96, 110, 130) and a method for protecting tissue against abrasion by attaching a pair of mutually overlying membranous layers (26, 28, 122, 124) to an area of a tissue surface such as a person's skin with only the peripheries of the layers interconnected with each other, so that the layers can easily slip along each other. An absorbent pad (88, 98) may be placed between one of the layers and the tissue, and may be impregnated with medication to be delivered to the tissue being protected. A quantity of a lubricant can be contained between the layers. The device is thin, to avoid causing pressure when it is used in restricted spaces, as within one's shoe. The device can also be implanted internally as where tendons move along an implanted plate.
