IPC: C09K11/02
Filed: 1995-08-30
Abstract: On peut améliorer les performances d'écrans au phosphore par apport d'un agent antistatique dans la couche supérieure de protection de l'écran radiographique, l'agent antistatique étant, de préférence, à base de fluorocarbone ou de silicone. Ces agents antistatiques sont particulièrement efficaces quand l'écran est réalisé par dépôt d'un mélange ou d'une dispersion de phosphore sur un substrat, tandis que le mélange ou la dispersion contiennent une quantité inférieure à 5 % en poids de constituants polymérisables, dont le poids moléculaire est inférieur à 300, de préférence, une quantité inférieure à 5 % en poids de constituants polymérisables, dont le poids moléculaire est inférieur à 500, la couche supérieure de l'écran contenant l'agent antistatique. On prépare cette couche supérieure, de préférence, par inclusion de l'agent antistatique dans la composition polymérisable et on laisse ensuite l'agent antistatique se déplacer vers la surface de la composition pendant la polymérisation, de manière à obtenir une couche constituée essentiellement par ledit agent. La composition polymérisable devrait être photopolymérisable et la quantité des autres constituants à l'intérieur du revêtement à photodurcir, dont les poids moléculaires sont inférieurs à 300 ou à 500, devrait être, de même, maintenue inférieure à 5 % en poids de la composition.

Patent CA-2205496-A1 (CA)
Title: Ram-air caboose
Inventor: RAMSAY L D
IPC: B60P3/32
Filed: 1997-05-27
Abstract: The Ram-Air Caboose is an attachment with adjustable weight distribution and air flow control fitted to the rear of a mini-van type vehicle and consists of a compartment that provides control of various air flows, weight distribution and counter balance. It has a vertical section secured with adjustable adaptors to a conventional class III trailer hitch, and an adjustable dihedral wing stabilizer extending horizontally forward and connecting to conventional van roof rack inserts with adaptors. Adjusting the dihedral wing stabilizer up will increase down air flow velocity pressure between the compartment and the vehicle, producing a degree of lift at the rear of the vehicle during forward motion. Conversely, lowering the stabilizer and raising the rear of the compartment creates down pressure. These adjustments improve vehicle stabilization and control at highway speeds. The Ram-Air Caboose's counter-balanced support system reduces vehicle rear sag and improves level by shifting load points as far forward on the vehicle chassis as practical. The dihedral wing stabilizer is also utilized as a torque extension to down load counter-balance pressure through adaptor connections. The interior of the dihedral wing stabilizer is open storage space. The vertical section contains the main open space, and windows that give safe rear vision through compartment front and rear walls. The Ram-Air Caboose can be used for work or recreation, and can be easily installed and removed.
Patent CA-2205684-A1 (CA)
Title: Fishing flies with improved properties
Inventor: EVANS ROBERT C
IPC: A01K85/08
Filed: 1997-05-16
Abstract: A method of coating a fishing fly to improve the durability and wetting character of the fly. The coating is applied using gas deposition, encapsulating the fly with a water barrier while preserving its micro-details. The typical coating is odourless and colourless, and increases the longevity of the fly. The wetting character imparted by the method results from the choice of gas deposited on thefly. In coating a dry-type fly, the method uses a gas that will make the fly hydrophobic so that it floats after a significantly greater number of immersions than an uncoated fly. In coating a wet-type fly, the method uses a gas that will make the fly hydrophilic so that it submerges in less time than an untreated fly.

Inventor: GRIFFIN LEE D
IPC: H04W92/08
Filed: 1996-07-26
Abstract: A system and method for indicating to a user that an operable connection or non-operable connection has been made between a portable radio and a vehicle kit forming a mobile communication system. The system determines if an operable connection has been made by determining if a hands-free-request signal, an external power signal, and an external antenna signal are present. Detection of the hands-free-request signal, external power signal, and external antenna signal are indicative that the portable radio and vehicle kit are operably connected such that the mobile communication system is fully operational. An operable connection alert indicative of an operable connection between the portable radio and vehicle kit is generated by a radio display and an external speaker in response to a determination that the hands-free-signal, external power signal and external antenna signal are present. In the preferred embodiment, the external antenna signal is determined by either comparing a measured received signal strength indicating (RSSI) with a reference RSSI value or detecting an increase in RSSI after inserting the portable radio into the cradle of the vehicle kit.
