Patent CA-2280315-A1 (CA)
Title: Dissimilar element mechanical and electrical connection and method (cadlok)
Inventor: OLLE RAY
IPC: H01R4/62
Filed: 1999-08-16
Abstract: A connection is provided between two dissimilar elements, such as an aluminum bus and a copper contact. Also provided is a method and apparatus for making the connection. One application is as an anode electrode hanger in an electric smelting furnace. The connection provides a lower resistance electrical connection which can be made while the power to the system is on. In a preferred form the contact is inserted and clamped in the bottom of a chamber in a refractory mold assembly. The chamber opening to the face of the mold assembly is somewhat deeper than the contact. The face of the mold assembly is clamped against the bus, and exothermic weld material is ignited to form a molten metal which drops into the chamber between the contact and bus. The weld metal forms a molecular weld bond with the bus, but only a mechanical interlock with the contact. To enhance the mechanical interlock and to improve the electrical conductivity, the surface area of the contact exposed to the weld metal is significantly increased, and the interlock formed increases both the strength of the connection and its electrical conductivity. The surface area increase is obtained by forming a series of parallel vertical undercut slots in the surface of the contact exposed to the weld metal, and such surface may also be tinned to form a brazed mechanical connection. The connection of the dissimilar metals can be made without shutting off the power and provides improved electrical conductivity.

Patent CA-2309649-A1 (CA)
Inventor: SVEC OTTO J
IPC: E02D29/12
Filed: 1999-08-24
Abstract: Frost heave of pavements around sanitary and storm sewer manholes (10) and similar installations disposed in an under the pavement (12), is a major and costly problem in cold climates. As a result of the frost heave, a difference in level is created between the manhole cover (32) and the pavement (12) around it. Due to traffic, pavement cracks are formed around the manhole (10) necessitating costly repairs. It is proposed to alleviate the problem to a substantial degree by providing a frost-heave mitigating structure in a direct vicinity of a manhole (10) or a similar installation. To this effect, a heat-transfer zone (16) filled with large granulate is formed around the manhole (10) under the pavement (12), and openings (26) are formed in the wall (24) of the manhole (10) in a way enabling heat transfer between the warmer interior of the manhole (10) and the colder heat-transfer zone (16). The heat that flows to the zone warms up the surrounding soil in the vicinity of the zone thus preventing its freezing and consequently the frost heave approximately above the zone.

Patent CA-2318330-A1 (CA)
Inventor: HJELMGREN HANS
IPC: G06F30/367
Filed: 1998-10-13
Abstract: The present invention relates to an improved system for simulating bipolar transistors with a variation in Early voltage as a function of collector/emitter bias voltage. The simulation is based upon a standard Gummel-Poon model and is improved by an Early voltage extension, where the constant Early voltage is replaced by an Early voltage that is divided into several regions. The Early voltage is adjusted to fit the actual variations of the measured Early voltage characteristics of a bipolar transistor. The Early voltage within each region is used for calculating the bipolar transistors base charge (qb) which then is used to simulate the performance of the bipolar transistor. The regions may be linked together by choice of boundary conditions.
