Patent CA-2156348-A1 (CA)
Title: Method of improving adhesion of durable coatings on weathered substrates and coatings made therefrom
Inventor: ROKOWSKI JOSEPH MARTIN
IPC: C08F299/00
Filed: 1995-08-16
Abstract: A latex binder suitable for producing high gloss coating on weathered substrates and a method for producing such coatings. The binder includes a low molecular weight and low acid number latex polymer having an acid functional and an enamine functional moiety that results from the reaction of ammonia or amine with an acetoacetyl functional pendant moiety on the latex polymer. A film containing the latex binder is applied on a substrate and then exposed to ambient light and air to produce a high gloss highly adherent film on difficult to adhere surfaces, such as weathered chalky substrates.

Title: Storage, transmission, communication and access to geographical positioning data linked with standard telephony numbering and encoded for use in telecommunications and related services
Inventor: EMERY MARK
IPC: H04M7/00
Filed: 1995-10-11
Abstract: A method and system implementation for combining and accessing telephony numbering and geographical position so direct access to information, services and goods may be invoked through the use of various telephone networks.  The existing telephone networks throughout North America and the world use standardized numbering plans for con-necting to, or switching any subtended device to any other device within the network. The U.S. government has orbited a series of communication satellites which pro-vide a signaling method for determining precise geo-graphical location throughout the world. This system is called the Global Positioning System (GPS) and provides several levels of service. Each GPS satellite continu-ally transmits a navigation location signal which may be received on the ground, sea, or in the air and when com-bined with signals from other GPS satellites used to pinpoint navigational position in two or three dimen-sions. This invention allows for the storage, transmis-sion, communication, and access to geographical position-ing data determined by GPS or any other method by using the North American or other land based public switched, cellular, satellite, radio, or other telephone system and related intelligent networks.

Patent CA-2172298-A1 (CA)
Inventor: HARMS DOUGLAS KEITH
IPC: E21B43/22
Filed: 1996-03-21
Abstract: A process in the removal of hydrocarbons from reservoirs involves the injection of a fluid that is primarily used to fracture and dissolve the host rock. To prevent the loss of this fluid down any one particular fracture, sealers are employed to restrict the flow of the fluid into opened fractures. Typically, these sealers are spherical in shape, and seat themselves in the perforations created in the casing of the Wilbur. Critical to the success of the ball sealers is the relationship between the density of the fracturing fluid and that of the ball sealers. It is known that ultra low density ball sealers are now required due to improved techniques of modern day hydrocarbon recovery. The ability to produce a ball sealer that can meet the criteria of ultra low density, high strength and chemical resistivity is hereby disclosed.     Through developments in the plastics industry, it is now possible to create a void filled, reinforced, injection molded ball that meets the criteria mentioned above and therefore suitable for application in the oil and gas industry.

Title: Method of recycling aluminum dross
Inventor: YERUSHALMI DANIEL
IPC: C04B35/111
Filed: 1995-02-07
Abstract: An improved method is disclosed for processing aluminum dross containing fluxing salts to provide a fired inorganic or ceramic product wherein the dross is processed to remove the fluxing salts therefrom, and a non-metallic product is recovered. The dross is processed through a crusher and the reduced fragments are classified by passing over a screen. A portion of the classified material is fed into a digester and a wet screen is used to screen the digested material. A portion of the screened material is sent to a dryer, passed through a dry screen and fed to a furnace. The improved process comprises mixing the non-metallic product with water and alkali materials to form a slurry and adding acid to neutralize the slurry. The slurry is adjusted by adding one of silica and alumina and the slurry is heated to form a fired product.

Direct or spot seeding with the pre-seeded shelter is easily carried out by setting the shelter in the soil and depressing the at least one flap to dislodge the seed retainer. The dislodged seed and the seed retainer fall by gravity to the seeding spot. Preferably, the shelter includes a base comprising a cylindrical portion so that the shelter may be set into soil by positioning it on the soil and rotating it while applying downward pressure. The displaceable cover may comprise at least one flap integrally attached to the shelter top or a seed retainer which can be retained in the first position by frictional engagement with the cylindrical shelter top.
