Patent CA-2229058-A1 (CA)
Inventor: CAMPENON BERNARD
IPC: C22B1/00
Filed: 1996-08-08
Abstract: Method for upgrading waste material comprising sheet metal with a zinc plating on at least one side thereof, including a) subjecting the waste material to a mechanical processing step to improve the accessibility of said zinc layers to a subsequent chemical etching by increasing the accessible etching surface of the zinc layer portions, this being achieved by crushing the waste material to separate the sheets from each other and by producing cracks in said zinc layers; this step is advantageously conducted in a shredder/mill; b) subjecting the waste material to a chemical etching step to dissolve the zinc by immersing it in a basic bath; and c) separating the zinc-free sheets from the chemical etching bath containing the dissolved zinc, which is then recovered by electrolysis. The invention particularly discloses the use of the above method for recovering and upgrading new scraps of zinc plated sheets in the automotive industry.
Patent CA-2229062-A1 (CA)
Inventor: KARLSSON LARS
IPC: B05D3/06
Filed: 1996-08-09
Abstract: On décrit un procédé ainsi qu'une installation de revêtement de poudre dans lesquels des objets (2) à revêtir de poudre sont préparés aux fins d'une rétention temporaire de celle-ci, après quoi on applique la poudre sur l'objet en une couche retenue sur celui-ci jusqu'à ce que la poudre, par fusion puis transformation en un état solide à l'aide d'une polymérisation, soit amenée à former une couche de revêtement sur la surface de l'objet. On prépare cette poudre de manière à ce qu'elle présente une température basse de fusion et d'amollissement, généralement inférieure à 100 ·C et de préférence comprise entre 60 et 100 ·C, et on lui ajoute un initiateur de polymérisation, conçu pour que ce matériau durcisse sous l'influence d'un rayonnement électromagnétique. La poudre ainsi préparée est chauffée sur l'objet jusqu'à ce qu'elle atteigne une température telle qu'elle entre en fusion et forme une couche adhérente sur les surfaces revêtues de l'objet. Ensuite, on soumet cette couche à un rayonnement, la durcissant ainsi afin d'obtenir une couche de revêtement couvrant les surfaces revêtues de poudre.

Title: Therapeutic azide compounds
Inventor: SCHINAZI RAYMOND
IPC: C07H19/20
Filed: 1996-09-06
Abstract: Pharmaceutical prodrug compositions are provided comprising azide derivatives of drugs which are capable of being converted to the drug in vivo. Azide derivatives of drugs having amine, ketone and hydroxy substituents are converted in vivo to the corresponding drugs, increasing the half-life of the drugs. In addition azide prodrugs are often better able to penetrate the blood-brain barrier than the corresponding drugs. Especially useful are azide derivatives of cordycepin, 2'-F-ara-ddI, AraA, acyclovir, penciclovir and related drugs. Useful azide prodrugs are azide derivatives of therapeutic alicyclic amines, ketones, and hydroxy-substituted compounds, including aralkyl, heterocyclic aralkyl, and cyclic aliphatic compounds, where the amine or oxygen moiety is on the ring, or where the amine or oxygen moiety is on an aliphatic side chain, as well as therapeutic purines and pyrimidines, nucleoside analogs and phosphorylated nucleoside analogs.

Patent CA-2245295-A1 (CA)
Inventor: BRENNER JERRY LAWRENCE
IPC: C08L21/00
Filed: 1998-08-19
Abstract: In a tire having a tread with cap/base construction, a regulated amount of partially crosslinked natural rubber in a tire tread compound increases the uncured ("green") stiffness, tensile strength and tear resistance of a green compound used for the base without adversely affecting physical properties of the tread after it is cured.  Such green stiffness is particularly useful in the construction of a tread for a pneumatic tire, which tread is of cap/base construction because stiffness provides requisite dimensional stability of both cap and base (in the tread) during the curing of the tire.  The amount of partially crosslinked natural rubber used in a tread compound depends upon the extent of crosslinking in the natural rubber, the non-crosslinked remainder being virgin latex.
