Patent CA-2184900-A1 (CA)
Title: Optical waveguide with flexible tips
Inventor: DOIRON DANIEL R
IPC: F21V8/00
Filed: 1993-10-07
Abstract: A flexible tip (10) for a medical catheter suit-able for the transmission of light and dimensionned to pass through extremely small tubular members is described.  The flexible tip, preferably made of optically transparent silicone elastomer (13), is af-fixed to the terminal end of a conventional optical fiber. In a preferred embodiment, the flexible tip comprises a central silicone core (11) surrounded by a cladding (12) having an index of refraction less than that of the core (11), permitting internal reflection.  The flexible tip is provided with an outer jacket (13) which serves two purposes: (1) it pro-vides structural integrity for the tip; and (2) it re-inforces the union between the flexible tip and the optical fiber to which it is abutted. The tip (10) en-ables the delivery of a comparable amount of light as a large glass fiber of equal core diameter but pos-sesses much greater flexibility. The tip (10) has the flexibility to be able to enter tortuous tubular mem-bers while retaining the light transmitting capabili-ties of relatively inflexible glass optical waveguides of the same diameter.

Patent CA-2193290-A1 (CA)
Inventor: LEMBCKE JEFFREY J
IPC: E21B33/12
Filed: 1996-12-18
Abstract: A packer or bridge plug is described which may be release by manipulation of the production tubing connected to it. If manipulation of the production tubing is unsuccessful in releasing the packer, the tensile strength of the production tubing need not be exceeded in attempting to remove the packer. Instead, the productiontubing is removed along with certain internal components of the packer. Thereaf-ter, heavy-wall tubing, with or without jars, can be lowered into the wellbore with a retrieving tool at the bottom of that string. The retrieving tool latches onto com-ponents of the packer to allow an alternative method of release which allows foruse of significantly higher tensile loads to liberate the packer from the wellbore.

Patent CA-2207746-A1 (CA)
Inventor: SIKS ANDREW R
IPC: G06F9/46
Filed: 1997-06-13
Abstract: A method of manipulating components through an network with enhanced performance and reduced network traffic includes providing a proxy application on a client computer and a remote windowing system on a server computer. The proxy application emulates, on the basis of instruction codes received from the server computer, the components of an application running on the server computer. The remote windowing system emulates, on the basis of activity packets received from the client computer, data input and user-initiated events provided by the windowing system of the client computer. In operation, when a user-initiated event is passed to the proxy application by the windowing system of the client computer, the proxy application encodes event data indicative of the event, and transmits the encoded event data to the server computer as an activity packet. Upon receipt of an activity packet, the remote windowing system in the server computer decodes the event data, and passes the event data to a selected component of the application for processing. Component changes resulting from processing of the event by the application are encoded by the remote windowing system and transmitted as instruction codes to the client system. Upon receipt of the instruction codes, the proxy application renders the component changes on the client computer. As a result, a user of the client computer is able to utilize the application as if it were running locally on the client computer, instead of running on a remote server computer. Network traffic between the client and server computers is reduced to encoded activity packets and instruction codes, which are small and can be transmitted quickly.

Title: Ratchet wrench
Inventor: WISBEY JAMES HARRY
IPC: B25B13/46
Filed: 1995-12-11
Abstract: A ratchet wrench comprises an output drive member (13, 37) rotatable about a first axis, a drive housing (15) containing the output drive member, and a handle (14) on the drive housing for rotating the drive housing about the first axis. A rotary member (24) within the handle is rotatable about a second axis and a drive ring (21) extends around the output drive member. A coupling means (25) couples the rotary member to the drive ring so that rotation of the rotary member about the second axis causes rotation of the drive ring about the output drive member. The wrench also includes primary ratchet means (17, 42) for selectively uni-directionally coupling the output drive member to the housing, and secondary ratchet means (23, 43) for selectively uni-directionally coupling the output drive member to the rotary member through the drive ring whereby the output drive member (13, 37) can be rotated in a selected direction either by rotation of the handle (14) or by rotation of the rotary member (24).

Title: Snowboarding simulator
Inventor: CURTIS CHRISTIANE
IPC: A63B69/00
Filed: 1997-07-15
Abstract: An apparatus designed to allow the user to simulate some of the basic skills, balance and movements of snowboarding. The apparatus has a modified snowboard with foot bindings attached and is mounted on an inclined platform, using a flexible rubber joint. The snowboard has rounded rocker blocks under each foot binding, extending from one side of the board to the other, which allow the user to simulate rocking from edge to edge on the snowboard as he/she pivots around the rubber joint attached just behind the front foot binding. The rounded rocker block under the front foot binding contains small wheels which along with the positioning of the rubber joint, allow the snowboard to pivot around this joint freely when the board is flat and the user's weight is concentrated on the front foot, thus simulating the movements required in a basic turn on a real snowboard.

Abstract: A retrievable bridge plug apparatus and retrieving tool, the retrievable bridge plug apparatus serving as a temporary bridge plug that can be set in casing in order to isolate the zone and aiding in the stimulation of the zone or test which would be conducted within the zone. The apparatus would include mechanical slips and compression type sealing packer rubbers with a mechanically operated J-slot for locking it in the running position or the set position. Further, the packer rubbers would be of sufficient size for allowing an annulus between the packer body and the wall of the casing for running and bypassing fluid as it travels in and out of the well, yet are sufficiently close tolerance to the casing for preventing extrusion when set and can be exposed to high differential pressure. There is further provided an equalizing valve for assuring equalization of pressure before the tool is released and providing additional area for bypassing fluid travelling in and out of the well for faster running of the tool in and out of the casing. It is further provided a running tool which would prevent the accidental loss of the bridge plug and threaded connections in the packer mandrel by permitting right or left hand torque to be applied.
