Patent CA-2260803-A1 (CA)
Title: Photocatalytically hydrophilifiable coating composition
Inventor: KANNO MITSUYOSHI
IPC: B01J37/02
Filed: 1997-07-16
Abstract: A composition is disclosed which can hydrophilify the surface of a member to impart an antifogging property to the surface of the member. The composition for hydrophilifying the surface of the member comprises at least (a) photocatalytic particles of a metallic oxide, (b) a precursor capable of forming a silicone resin film or a precursor capable of forming a silica film, and (c) a solvent, the total content of the photocatalytic particle and the solid matter of the precursor in the composition being 0.01 to 5% by weight. The hydrophilic property can be imparted simply by applying the composition onto a member and drying or heating the composition applied to the member. The resultant hydrophilic thin film is transparent and, hence, does not sacrifice the transparency and appearance of a member required to be transparent. Further, the surface of a member with the above composition applied thereto has such a property that water droplets adhered thereon can be immediately removed by vaporization and the surface is less likely to be soiled and, even when a contaminant is adhered thereon, can easily release the contaminant therefrom.

Patent CA-2268144-A1 (CA)
Title: Hydrocarbon conversion using large crystal zeolite catalyst
Inventor: VERDUIJN JOHANNES P
IPC: C07C5/27
Filed: 1997-10-17
Abstract: A process for converting hydrocarbons by contacting a hydrocarbon feedstream under hydrocarbon conversion conditions with a large crystal zeolite catalyst. The large crystal zeolite of the catalyst used in the hydrocarbon conversion process is made by heating an aqueous zeolite synthesis mixture under agitation to a temperature equal to or less than the effective nucleation temperature of the synthesis mixture. After this step, the aqueous synthesis mixture is heated in the absence of agitation to a temperature equal to or greater than the effective nucleation temperature of the aqueous zeolite synthesis mixture. The process finds particular application in hydrocarbon conversion processes where reduced non-selective acidity is important for reaction selectivity and/or the maintenance of catalyst activity, e.g., toluene disproportionation, dealkylation, alkylation, and transalkylation.
Patent CA-2268543-A1 (CA)
Title: Transparent record access manager for a disk drive
Inventor: BOVATSEK KENNETH JOHN
IPC: G06F3/06
Filed: 1999-04-12
Abstract: In a disk drive, a transparent record access manager centralizes access to system cylinder records in two global routines for reading and writing to the system cylinder records, and a system cylinder table which maintains address information for the system cylinder records. Internal firmware system cylinder record users and host software programs access system cylinder records through the system cylinder record manager, which in turn locates system cylinder records through the system cylinder table. The transparent record access manager makes any changes to the address or length of a particular system cylinder record transparent to the users of all other system cylinder records. An ATA command process allows a host processor to access a system cylinder record through the read and write routines, or to recieve the system cylinder table from the disk drive.

Patent CA-2280758-A1 (CA)
Inventor: RICHTON ROBERT ELLIS
IPC: G01S19/25
Filed: 1999-08-26
Abstract: The invention is directed towards a method for estimating a PRN  synchronization and Doppler shift of a satellite signal at a reference location within a cell and sector of where a wireless terminal or WAG client is located. The estimates are based on information conveyed by a GPS signal acquired by an auxiliary system or WAG server, which may be at a location different from the wireless terminal or WAG client. The PRN synchronization and Doppler shift estimates are also based on some reference time, which is a time that is sufficiently far into the future to allow the WAG client to demodulate and decode the PRN synchronization and Doppler shift estimates from as assisting message transmitted by the WAG server and to use such estimates to acquire GPS signals, wherein the assisting message indicates the PRN synchronization and Doppler shift estimates.
