Title: Ratchet assembly for winding a counterbalancing mechanism of a door, door assembly including the same and kit for assembling the ratchet assembly
Inventor: SAVARD NORMAND
IPC: F16D41/08
Filed: 2003-07-17
Abstract: A ratchet-like assembly for winding a counterbalancing mechanism of a door. The ratchet-like assembly includes at least one plate, at least one ridge, an actuator, and at least one pawling element. Each plate is operatively mounted onto a fixed structure and includes an orifice through which extends a shaft of the counterbalancing mechanism and about which the shaft is rotatable along opposite first and second directions of rotation. Each ridge is provided about an outer edge of the corresponding orifice. The actuator is operatively connected to each plate and is operable between a locked configuration and an unlocked configuration. Each pawling element is mounted onto the actuator and is positioned within a corresponding ridge, adjacent to the shaft, Each ridge and each corresponding pawling element are shaped and sized so that when the actuator is operated in the locked configuration, each pawling element is operatively pressed against the shaft and its corresponding ridge for preventing the shaft from rotating along the first direction of rotation, and when the actuator is operated in the unlocked configuration, each pawling element is operatively urged away from the shaft and its corresponding ridge for allowing the shaft to rotate along both the first and second directions of rotation. The present ratchet-like assembly enables to easily install and calibrate counterbalancing mechanisms of various types of door assemblies where a torque must be applied and maintained onto a given shaft of the door assembly.

Abstract: A wireless and hoc pico network is formed by eyewear and other devices sucha as a computer, a bracelet and a telephone having similar transceivers mounted on them. Master slave relationships are configurable. Other devices, such as a radio, a CD plaxer, a hand held global positioning satellite system and a heart rate monitor, having similar transceivers, can also be connected with the transceiver of the eyewear. The transceivers operate on globally available, unlicensed radio band, 2.45 gigahertz (GHz) and conforms to the Bluetooth standard. The power consumption of Bluetooth enabled devices is less than three percent of the power consumption of a mobile phone. The eyewear includes a frame and connected to the frame are two temples. Temples are connected to frame via hinges. Temples have a male portion of a connector incorporated in them. Female portion of the connector is made integral with the hinges. When the male portion is inserted in the female portion the temple is attached to the frame. The temples can be removed by pulling the connector apart, and a temple with different apparatus within it can be inserted in place of the removed temples. The temple may have co-molded within its body, an apparatus such as an audio device, a camera, a speaker, and a microphone, and a display device such as liquid crystal or an alarm. In another embodiment, eyewear constitutes a distance alarm to monitor the movement o, for example, a child. A device in form of, for example, a bracelet is worn by the child. The transceivers in the eyewear and the bracelet form a small-range wireless network, i.e., piconet, wherein the eyewear and the bracelet communicate using signals conforming to the Bluetooth technology. The transceiver in the eyewear is configured to generate an alarm when the bracelet exceeds a predetermined distance from eyewear.

Patent CA-2460954-A1 (CA)
Title: Dry mix for water based drilling fluid
Inventor: HAYES JAMES
IPC: C09K8/12
Filed: 2002-09-19
Abstract: A drilling fluid or mud having several components, including leonardite (hum ic acid); potassium acetate; partially hydrolyzed polyacrylamide (PHPA); polyanionic cellulose polymer (PAC); sulfonated asphalt; sulfoalkylated tannin; polystyrene maleic anhydride copolymer; micronized cellulose fiber; calcium carbonate; and calcium carbonate. These components are preferably premixed in a dry formulation as a powder or as pellets, and shipped to the site in bags or bulk barrels. This offers substantial advantages over the prior art in that the drilling mud of the present invention may be formed simply by adding the dry mix to a predetermined amount of water, and is thus much easier to make than the prior art wet mix drilling fluids, which typically require precise ratios of several different powders and liquids to be mixed together. The humic acid serves as hydration buffer to help keep th e powder or pellets dry and flowable.
