Patent CA-2229704-A1 (CA)
Inventor: JALBERT GAETAN
IPC: E01C11/14
Filed: 1998-03-17
Abstract: A ground cover with an improved resistance to degradation by freezing and thawing, a kit for the manufacture of the ground cover and a method for manufacturing such a ground cover. The ground cover has a plurality of molds each having a bottom wall and side walls. The molds have their bottom walls laying flat onto the ground and are positioned with their side walls in close adjacent relationship with respect to each other so as to fully cover the ground. Connectors of given flexibility extend through the side walls of pairs of adjacent molds in order to connect the molds to each other. A filling material is poured and hardened into said molds. The filling material acts as a covering. Once installed, the ground cover forms a network that can easily be adapted to floor surfaces of different shapes. The cover is prepared by attaching together similar units made from a kit consisting of the molds and the connectors of given flexibility. Of course, the number of elements in the kit is proportional to the surface to be treated. When connected together, the molds can receive the filling material which is preferably concrete. When cured and hardened, the filling material, together with the flexible connectors and the molds, provide the cover with a high resistance to degradation due to freezing or to thawing, thereby making them suitable for countries like Canada or the northern part of the United States.
Patent CA-2233281-A1 (CA)
Title: Fire suppression system
Inventor: BIEHL RICHARD
IPC: A62C35/02
Filed: 1998-03-26
Abstract: The present invention relates to a fire suppression system and method in which an extinguishing agent is automatically discharged from a limited source of supply of the wet chemical extinguishing agent for rapid extinguishment of the fire, followed by water application to the locus of the fire from an unlimited source of supply of water. The subsequent automatic application of water provides rapid cooling of the hot burning material below its reflash temperature. The present hybrid system exploits the best fire suppression properties of both agents against fires i.e. the wet chemical extinguishing agent provides rapid flame extinguishment and water provides rapid cooling following extinguishment. The present hybrid system is significantly more robust (fire test variables are less critical to its fire suppression performance) than current water or wet chemical agent systems.

Patent CA-2246683-A1 (CA)
Inventor: HARPER IAN GEORGE GWINNETT
IPC: B60T1/04
Filed: 1998-09-22
Abstract: In a disc braking system for bicycles and other vehicles so equipped with disc brakes on the front wheel, it is known that the brakes are activated through the manipulation of a lever and that by hydraulic or cable connections the pads contained in the brake calliper(s) are induced to press upon the disc causing the rotating wheel to slow and, if the application continues, stop.    In this invention the front brake calliper is mounted on a swing-arm having an axis of rotation or pivot around the wheel axle. Attached to the end of each swing-arm is a rod which extends upwards to connect to a brace plate through which the front suspension fork assembly passes. The connection of the rod to both the swing-arm and the brace plate is accomplished through pivoting joints.  This invention (MECHANICAL ANTI-DIVE BRAKING SYSTEM) prevents the compression ("dive") of the front suspension during the application of the front disc brake by transferring brake energy to the frame rather than to the lower moving section of the suspension forks. It does not, however, prevent the front suspension from operating independently to full effectiveness before, during, or after the application of the brakes.   The invention is comprised of the swing-arm, the energy trasfer rod, and the brace-plate. It is envisioned that adaption to specific suspension or axles would be performed as required to implement the invention but this invention makes no claim to a particular suspension system or axle system.

Filed: 1997-05-30
Abstract: This invention is related to adenoviral (Ad) vectors and their applications in the field of genetic medicine, including gene transfer, gene therapy, and gene vaccination. More specifically, this invention is related to the Ad vectors that carry the minimal cis-element of the Ad genome (mini-Ad vector) and are capable of delivering transgenes and/or heterologous DNA up to 36 kb. The generation and propagation of the mini-Ad vectors require transcomplementation of a packaging-attenuated and replication-defective helper Ad (helper) in an Ad helper cell line. This invention further comprises a methodology for generating a mini-adenoviral (mini-Ad) vector for use in gene therapy of hemophilia and animal test systems for in vivo evaluation of the Ad vectors. More specifically, this invention describes factor VIII (FVIII) Ad vectors that only contain minimal cis-element of the Ad genome (so-called miniAd) and comprise a human FVIII cDNA with other supporting DNA elements up to 36 kb. The FVIII mini-Ad can be generated and preferentially amplified through the assistance of a packaging-attenuated helper Ad and a helper cell line. This invention also reports designs and methods for producing transgenic mouse models that can be used for in vivo testing the mini-Ad.

Patent CA-2261510-A1 (CA)
Inventor: KELLEY JOHN W
IPC: G01V7/16
Filed: 1999-02-11
Abstract: In the following paper we propose a new and novel "SYSTEM" for making hyperfine airborne gravity-gradiometry measurements. The "SYSTEM" consists of both a "PROCESS", and several possible "DEVICES" for carrying out the proposed process. The method involves making high-resolution measurements of the gravitational redshift of photons while the measuring instrument is put into momentary freefall. The idea is revolutionary because it could theoretically eliminate all of the external accelerations that normally arise in such surveys, including those from the aircraft itself. These external accelerations are completely indistinguishable from a superimposed g-field, and are thus the limiting factors to the survey resolution in current airborne gravity exploration. The method can thus potentially give gravitational gradient resolutions several orders of magnitude better than what has been possible up to now.
