Patent CA-2366151-A1 (CA)
Title: Insulator
Inventor: OGURI NORIYASU
IPC: H01B17/38
Filed: 2001-12-21
Abstract: Use of alumina cement mortar is enabled as a source material of a cement kneaded product cured body for joining hardwires onto an insulator body, whereby an insulator can maintain a high mechanical strength (initial strength, long-term strength) and a high electrical strength for a long period of time, and the curing time in forming the cured body is shortened to reduce the cost of producing the insulator. As a source material of a cement kneaded product cured body for joining hardwires one makes use of an alumina cement mortar obtained by kneading an alumina cement having a specific surface area of at least 3500 cm2/g, a polymer-steric-hindrance type water reducing agent, an aggregate, and water, or an alumina cement mortar obtained by kneading an alumina cement having an amorphous phase on an outer peripheral surface of particles and having a specific surface area of at least 3500 cm2/g, a water reducing agent, an aggregate, and water.

Abstract: A low-emissivity multilayer coating includes, in order outward from the substrate, a first layer including a layer containing titanium oxide, a layer containing silicon nitride, or a sublayer layer containing titanium oxide in combination with a sublayer containing silicon nitride; a second layer including Ag; a third layer including at least one layer selected from titanium oxide layers and silicon nitride layers; a fourth layer including Ag;  and a fifth layer including silicon nitride. The color of the coatings can be varied over a wide range by controlling the thicknesses of the layers of titanium oxide, silicon nitride and Ag. A diffusion barrier of oxidized metal protects relatively thin, high electrical conductivity, pinhole free Ag films grown preferentially on zinc oxide substrates. Oxygen and/or nitrogen in the Ag films improves the thermal and mechanical stability of the Ag. Dividing the first layer of titanium oxide, the Ag layers, and/or the third layer with a sublayer of oxidized metal can provide greater thermal and mechanical stability to the respective layers.

Filed: 2000-04-25
Abstract: The present invention pertains to the field of fire-fighting technology and can be used for protecting equipment and persons when extinguishing fires, for dividing the volume of buildings in surface or underground structures or installations into fire-proof compartments, for providing protection against the collapse of ceiling structures and for locating the progression of the flame front in large-scale fires resulting in ecological disasters. The purpose of this invention is to develop a method for attenuating with an improved efficiency the energy flow consisting of light, heat and convection gas flows, and to develop a device of the gun-carriage type for creating a thermal-radiation protection screen which is more reliable, harmless and easy to implement and which provides protection against light radiation and convection gas flows. This method involves creating a curtain of a cooling liquid that is sprayed into space between surfaces. When creating more than one curtain, the method involves using a combined supply of cooling liquid. One of the curtains is formed by spraying the liquid, while the following curtains are formed by supplying an aerated mechanical or chemical foam. The device includes a mounting assembly, a spraying unit as well as grids arranged on both sides of a frame so as to define a gap. Nozzles are further mounted in the openings formed in the tubes of the frame.

IPC: G16B25/10
Filed: 2000-05-25
Abstract: The present invention relates to a highly accurate and reproducible mathematically-based methodology for quantifying the levels of differential gene expression from microassay protocols. Specifically, the present inventi on provides a simple deductive approach, grounded in a Bayesian framework, to circumvent the heuristic-based limitation of previous methodologies. Rather than seeking a point-estimate of the fold-change of the level of gene expression, the present invention utilizes the derivation of mathematical formula to determine the a posteriori distribution of all the fold-changes o f differential gene expression which may be inferred from the given measurements. From this a posteriori distribution the following information may be obtained: (i) an estimator for the fold-change of the level of gene expression; (ii) confidence limits for the fold-change, at any given confidence level; and (iii) a P-value for assessing the statistical significance of change. The present invention also possesses the advantage that fold-change estimates and confidence limits may even be assigned to signal pairs where both signals are zero or negative, without resorting to heuristic thresholds.

Title: Method and device for analysis of biological specimens
Inventor: EMMERT-BUCK MICHAEL R
IPC: C12Q1/6841
Filed: 2000-07-26
Abstract: Disclosed herein are substrates having different capture regions, such as contiguous layers, wherein the different capture regions of the substrate contain different identification molecules. Components of the specimen are transfered through the capture regions under conditions which allow the components to interact with different identification molecules in the different regions of the substrate. Transfer is effected by capillary action of a solution moving through the cellular specimen or by electrophoresis. The transfer may occur in such a way as to maintain a geometric correspondence to the specimen, e.g. a correspondence to the cytoarchitecture of a cellular specimen. Example of cellular specimens include tissue sections such as tumor tissue sections. Cytostat sections cut slightly thicker than usual, i.e. 25 to 50 µm, allow the detection of molecules of moderate and low level abundance.

Abstract: A cushioning conversion machine having a novel former around which a sheet material is folded to form an improved cushioning product. The former has longitudinally spaced side surfaces inclined from bottom to top toward a downstream end of the machine. The side surfaces cause the obstruction of th e sheet stock material upstream of the side surfaces so that the sheet materia l crumples in the spaces upstream of the side surfaces, thereby increasing the  cushioning properties of pillow portions of the cushioning product. The form er also has a centrally located base plate which minimizes crumpling in a centr al portion of the sheet material so that the folded over portions and the centr al portion can be connected to maintain more effectively the shape of the pillo w portions in the resulting cushioning product. In addition, the former has a guard plate mounted above longitudinally spaced bottom edges extending laterally outwardly from the base plate and upstream from a vertical central  plane. The former also has a pair of mandrels at its downstream end which internally fluff the crumpled pillow portions before the central portion is connected. The machine also has a width adjustment device for selectively adjusting the width of the resulting cushioning product.

Abstract: In a shoe press belt, in which the nip zone is narrower than the shoe width, the shearing force which normally acts on the belt at the outer boundary of the nip zone is made either weak or non-existent by forming the outer portions of the belt of less hardness than the inner, or central, portion of the belt, so that the less hard portions can be positioned directly opposite the outer boundaries of the nip zone. Alternatively, the outer portions of the belt can be made thinner than the central portion of the belt and the thinner portions positioned directly opposite to the nip zone boundaries. The shearing force applied to the belt at the nip ends of the roll is reduced or eliminated, cracking resulting from the shear force is reduced or avoided, and a belt having improved durability results.
