Patent CA-2204008-A1 (CA)
Title: Optical device having low visual light transmission and low visual light reflection
Inventor: YANG PETER Y
IPC: G02B1/10
Filed: 1995-10-26
Abstract: A solar control film having low visible light transmittance and low visible light reflectance is comprised of two or more transparent substrates (14) each bearing a thin, transparent, discontinuous, incoherent film of metal (18) having low visible light reflectance and a degree of visible light blocking capacity, the substrates being so assembled and laminated into a composite (10) that the visible light blocking capacities of the metal films are effectively combined to provide a composite having low visible light transmittance as well as low visible light reflectance. Performance characteristics are enhanced by providing on one or more of the substrates a transparent coating (16) of high refractive index underlying the metal film.  The material of high refractive index is preferably a synthetic high oxygen content oxide of bismuth, which facilitates efficient and economical production of the solar control film.

Title: System for preventing gear hopout in a compound transmission
Inventor: DUTSON BRIAN JOSEPH
IPC: F16H57/021
Filed: 1997-06-13
Abstract: An improved compound transmission design is provided for reducing gear hopout, particularly during PTO operation.   In this design, a spindle is rigidly secured to the input shaft, and a headset/fourth gear is rotatably mounted on a spindle by means of  a full compliment needle bearing.  A splitter gear is rotatably mounted on the input shaft and includes a sufficient diametral float with respect to the input  shaft to minimize  tipping  of  the  gear  while  maintaining significant torque balance between countershafts.  This configuration maintains concentricity in parallelism of the headset/fourth gear and splitter gear with respect to the synchronizer clutch in order to prevent gear hopout.

Title: Casein phosphopeptide, casein containing same and process for the preparation thereof
Inventor: HAN SANG KEE
IPC: A23L33/155
Filed: 1996-03-22
Abstract: The present invention relates to a ca-sein phosphopeptide (CPP) having a novel amino acid sequence and a casein including same wherein the 25th Arg from N-terminal in a conventional CPP is replaced by Cys, rendering the CPPs to form a dimer by disul-fide bond. In the corresponding DNA  se-quence, cytosine is replaced by thymine to cause the amino acid replacement from Argi-nine(Arg) to Cysteine(Cys). The CPP or the casein containing same has an improved ability of solubilizing minerals and absorb-ing thereof in animals. The CPP or the beta--casein H containing same can be added to foodstuffs, beverages, medication, cosmet-ics, feed in an effective amount of enhanc-ing a mineral absorption in animals.

Title: Method of providing telecommunications services
Inventor: LOW COLIN
IPC: H04M3/487
Filed: 1996-12-11
Abstract: Traditional IN (Intelligent Network) services in a PSTN use service logic and data that is accessible for use only by the PSTN, though provision may be made for users to change certain controlled parameters of the services. The present system has the service logic and data ("service resource items") placed on servers (51) accessible over the Internet (50). This permits service resource items to be accessed from the service control subsystem (42) of a PSTN on a worldwide basis using the highly-resilient infrastructure of the Internet (50). Furthermore, the updating of the service resource items can be made the responsibility of the party to whom the service resource item relates, such updating being readily effected by access direct to the server (51) holding the resource items.

Title: Fraud detection data processor
Inventor: CARNEY JAMES F
IPC: G06Q20/04
Filed: 1997-01-17
Abstract: A system and method for detecting and thus preventing check fraud utilizing a digital computer with image capture (260) and interpretation systems. The system converts the payee information (10), issue date (20) and the MICR line information (account number (40), check number (30) and dollar amount (50)) to a check digit which is then placed into the MICR line of a check, printed on its face or transmitted via the paid issuance file to the drawee bank. The drawee bank, upon presentation, utilizes a transformation algorithm to convert the printed payee information (10) and issue date (20) on the check into a numerical value that is combined with MICR line information (30, 40, 50) and a check digit is calculated based upon pre-agreed logic. This unique data processing system quickly confirms properly presented checks (600) while effectively precluding payee and other alterations in a cost effective manner.

Abstract: A beverage container having elongated side walls is provided. The container side walls are preferably generally cylindrical and having an upper end and a lower end.  The container also having a base portion that is connected to the side walls at the lower end of the side walls. The container further includes a stabilizing arm that has a first end and a second end. The stabilizing arm is movably connected to the base portion so as to be movable with relation thereto. The stabilizing arm may thus be moved from a position in which the stabilizing arm first end is proximate to the base portion and lies in substantially the same plane as the base portion to a position in which the stabilizing arm first end is extended away from the base portion and lies in substantially the same plane as the base portion. The first end of the stabilizing arm, when extended away from the base portion, may be inserted within the crease between the seating portion and the back support portion of a vehicle seat. The stabilizing arm is preferably movably connected at the second end of the stabilizing arm to the base portion through a hinge, which may be an interconnected element sir a section of relatively flexible material. Alternatively, the base portion may further have a track provided thereon and the stabilizing arm may be movably connected to the base portion by being disposed within such track. The first end of the stabilizing arm preferably includes an aperture disposed therethrough which allows the user to more easily manipulate the stabilizing arm.

Title: Process and device for determining the oxidisable substance content of aqueous liquids
Inventor: SIEPMANN FRIEDRICH W
IPC: G01N21/3504
Filed: 1997-04-26
Abstract: To determine the oxidisable substance content of aqueous liquids, a sample chamber (1) is filled with the liquid and emptied again, a small quantity of the sample remaining on a heating element (10) projecting into the sample chamber (1). With the sample chamber closed, the heating element is briefly heated, whereupon the adhering quantity of sample evaporates and the oxidisable substances are burnt. The pressure or moisture increase thereby occurring is used to determine the quantity of the sample. The quantity of exhaust gas produced by combustion is found by infra-red measurement and the oxidisable substance content, especially carbon or nitrogen, is found from both values (quantity of sample, and quantity of exhaust gas).
