Patent CA-2195435-C (CA)
Inventor: CIOBANU DAN A
IPC: H02G5/06
Filed: 1995-06-26
Granted: 2000-11-21
Abstract: A bus coupling (10) for connection to bus (12 and 14) in an electrical system comprises a coupling having a substantially cylindrical outer surface (16) and an inner surface (18) for receiving the bus. A portion of the outer surface of the coupling (50) and the bus are compressed by a swaging tool until they plastically deform radially inwardly to form a swaged connection. An antioxidant composition (28) may be applied between the coupling and the bus, with an annular groove (22) in the inner surface of the coupling accumulating any of the excess composition. A counterbore (24) on the inner surface at one end of the coupling may be filled with a sealing material (30) to prevent water accumulation that could weaken the connection in freezing climates. The one end of the coupling also has a smooth curved surface to reduce the adverse consequences normally associated with the corona effect.

Title: Corrosion preventing buffer system for metal products
Inventor: WEBB DAVID R
IPC: C23C28/00
Filed: 1995-10-19
Granted: 2001-08-07
Abstract: A system is disclosed for inhibiting the corrosion of ferrous and other meta ls by passivating the metals. The system includes novel buffered compositions which may be applied to metal products for preventing or retarding corrosion  and methods for applying the buffered compositions to metal products such th at corrosion protection of the products is achieved through passivation. The methods include an in-situ application to existing structures with metal reinforcement as well as applications to metal products during manufacture. Generally, the compositions may be in various forms and comprise a carrier component and one or more pH buffer components. The buffer is selected to retain the proximity of the metal at a pH at which the metal is passive to corrosion. The compositions are environmentally friendly and are capable of replacing chromates which have been traditionally used with zinc and zinc alloys to inhibit corrosion of metals but which are potentially harmful to t he environment.

Title: Belts for compliant calendering
Inventor: DUTT WILLIAM H
IPC: D21F7/08
Filed: 1997-08-08
Granted: 2004-05-18
Abstract: A calender belt for the compliant calendering of a paper web includes an endless base substrate, a staple fiber batt attached to at least the outside of the endless base substrate, and a polymeric resin material totally impregnating the fiber/base composite structure comprising the endless base substrate and the staple fiber batt to a substantially uniform depth. That depth may be such that the polymeric resin material does not reach the base substrate, or partly or completely impregnates the base substrate.      A layer of polymeric resin material is built up upon the staple fiber material to a predetermined thickness. Once the polymeric resin material is cured, it is ground to a desired smoothness without exposing any fiber on the ground surface. That the penetration of the polymeric resin material into the staple fiber batt, and possibly into the base substrate, is to a uniform depth enables the calender belt to provide a uniform pressure pulse as it passes with a paper web through the nip in a compliant calender.

Abstract: A selectively activated time-temperature integrating device for providing a visually observable indication of cumulative thermal exposure, in which a viscoelastic material migrates into a diffusely light-reflective porous matrix at a rate which varies with temperature to progressively change the light transmissivity of the porous matrix and thereby provide the visually observable indication. The viscoelastic material can comprise a pressure sensitive adhesive. The visually observable indication can comprise latent indicia which initially are not visible and become visible, obscurable indicia which initially are visible and become obscured, or a combination of both. Various actuating means for selectively switching the indicator from an unactivated state to an activated state are described. Also disclosed are a method for providing a visually observable indication of cumulative thermal exposure and a method for providing a time and temperature integrating device for providing a visually observable indication of cumulative thermal exposure of an object.
Patent CA-2215422-C (CA)
Inventor: MAXWELL VICTOR FREEMAN
IPC: E21B33/138
Filed: 1997-09-15
Granted: 2002-04-02
Abstract: A process and a material for use in sealing casing lining in a borehole is taught. The process includes the placement of a bitumen sealant material in a position between the casing tube and the wall of the borehole to be maintained in this annulus by means of a retaining devise such as an external casing packer or with the placement of a retainer made of cement grout and situated at the lower end of the casing tube. The bitumen sealant material prevents the passage of fluids vertically through the borehole. The sealant material remains viscous over time and can flow to fill voids which may occur in the rock formations adjacent to the borehole, or in the steel casing of the casing tube. To improve the sealing capabilities of the bitumen material a measured amount of fine grain weight material can be added to the bitumen to increase the density of the sealant material and thereby increase the hydrostatic pressure that the column of bitumen sealant will exert on the bottom and the walls of the borehole.

Granted: 2002-01-08
Abstract: A computerized switching system for coupling a workstation to a remotely located computer. A signal conditioning unit receives keyboard and mouse signals generated by a workstation and generates a data packet which is transmitted to a central crosspoint switch. The packet is routed through a crosspoint switch to another signal conditioning unit located at a remotely located computer. The second signal conditioning unit applies the keyboard and mouse commands to the keyboard and mouse connectors of the computer as if the keyboard and mouse were directly coupled to the remote computer. Video signals produced by the remote computer are transmitted through the crosspoint switch to the workstation. Horizontal and vertical sync signals are encoded on to the video signals to reduce the number of cables that extend between the workstation and the remote computer. The signal conditioning units connected to the workstations include an onscreen programming circuit that produces menus for the user on a video display of the workstation.

Abstract: The present invention provides a flotation cell that includes a tank and an impeller rotatably disposed in the tank for suspending solids and dispersing air in a pulp phase or slurry in the tank, thereby generating froth from the pulp phase. A plurality of substantially radially oriented stationary baffle plates are disposed in the tank for reducing angular momentum of the froth while enhancing radial momentum thereof. Each of the baffle plates extends essentially through the entire layer of froth and the pulp phase or slurry. In another aspect, a plurality of radially oriented launders in fluid communication with a circumferential launder are disposed in the tank. A secondary launder, concentric with the central launder may also be placed in the tank. The radial launders are in fluid communication with the central launders and the secondary launder. This network of launders allows froth to collect at various points throughout the flotation cell, thereby increasing the froth collection efficiency.
