Patent CA-2304728-A1 (CA)
Inventor: ROSENBAUM WALTER
IPC: G10L15/24
Filed: 1998-09-21
Abstract: The invention relates to a method and device for recognizing delivery data on mail matter due to video coding fields (40), whereby recorded, digitalized and stored pictures of the mail matter areas are transmitted after undefined automatic assessment of said delivery data by an OCR unit (100). According to said method, at least the names are entered by means of the character entry unit (60, 70). Candidates for character recognition are then selected based on the indefinite results of the automatic OCR assessment. The inventive method is particularly practical inasmuch as it enables selection by comparing either the determined number of signs, or the candidate signs from a positional point of view, with the signs determined by means of the OCR unit, taking the probabilities into account.

Patent CA-2321514-A1 (CA)
Title: Multiple layered coating on heat-sensitive substrates
Inventor: ALLEN KAREN D
IPC: B05D7/06
Filed: 2000-10-02
Abstract: A heat-sensitive substrate is coated with a first, low-temperature curing coating powder and a second, high-temperature curing coating powder. The time/temperature conditions of fusing and curing the low-temperature coating powder permit the substrate to retain its character and thus suffer no essential damage to the character of the substrate. The time/temperature conditions of fusing and curing the high-temperature coating powder would so damage the substrate if the high temperature curing coating powder were applied, fused, and cured, directly on the substrate. However, the coating provided by the low-temperature curing powder protects the substrate from detriment when the high-temperature curing coating powder is fused and cured thereon.

Patent CA-2337873-A1 (CA)
Inventor: ZHOU SHU-ANG
IPC: H01P1/203
Filed: 1999-07-16
Abstract: A low-pass or band-rejection filter for microwave frequencies has a substantially planar structure and is constructed of a transmission line having inductor portions (10) and wider capacitor portions (11). The inducto r portions are designed as linear microstrip elements having widths being vari ed by making areas (13) at the sides of the linear elements (10) superconductin g. In changing the widths of the transmission line also the inductances thereof  are changed accordingly. The areas (13) at the sides of the microstrip elements comprise rather narrow areas located directly at the central, norma l metal conductor (9). These narrow areas (13) have in the non-superconducting  state some electrical conductivity which can be small but still not quite insignificant in relation to that of the metal conductor. However, owing to the fact that they contact the normal metal conductor (9) only at very narro w edges instead of contacting it at a large surface they do not significantly affect the transmission characteristics of the transmission line in the norm al state of the areas which can be made superconducting.

Title: Cementitious dry cast mixture
Inventor: OSBORNE JESSE
IPC: C04B24/12
Filed: 1999-07-30
Abstract: The present invention is directed to cementitious dry cast mixtures for forming cementitious articles, particularly a cementitious dry cast mixture containing a dispersant, wherein said dispersant is a derivatized polycarboxylate dispersant which is a polymer comprising units derived from at least a substituted carboxylic acid monomer or substituted ethylenically- unsatured monomer, and optionally including at least one of an unsaturated hydrocarbon, an N-polyoxyalkylene maleimide, and a condensation product of a n unsubstituted carboxylic acid monomer and an alkoxypolyoxyalkylene primary amine substituted carboxylic acid monomer. The cementitious dry cast mixture  has a reduced effective dose of dispersant; compacts and consolidates in response to vibration energy; reduces the cycle time in the production of articles manufactured from dry cast mixtures; provides for increased green strength, density, and early compressive strength; and improves the surface aesthetics of articles manufactured from dry cast mixtures. Additionally, a surface active agent/air entraining agent can be included in combination wit h the dispersant to provide for increased swipe effect.
