Patent number: 6797018Abstract: An electrochemical energy storage device includes a number of solid-state thin-film electrochemical cells which are selectively interconnected in series or parallel through use of an integrated interconnect board. The interconnect board is typically disposed within a sealed housing which also houses the electrochemical cells, and includes a first contact and a second contact respectively coupled to first and second power terminals of the energy storage device. The interconnect board advantageously provides for selective series or parallel connectivity with the electrochemical cells, irrespective of electrochemical cell position within the housing. Fuses and various electrical and electro-mechanical devices, such as bypass, equalization, and communication devices for example, may also be mounted to the interconnect board and selectively connected to the electrochemical cells.Type: GrantFiled: May 30, 2003Date of Patent: September 28, 2004Assignees: 3M Innovative Properties Company, Hydro-Quebec CorporationInventors: Jean Rouillard, Christophe Comte, Dominik Daigle, Ronald A.

Patent number: 6569559Abstract: An improved electrochemical generator is disclosed. The electrochemical generator includes a thin-film electrochemical cell which is maintained in a state of compression through use of an internal or an external pressure apparatus. A thermal conductor, which is connected to at least one of the positive or negative contacts of the cell, conducts current into and out of the cell and also conducts thermal energy between the cell and thermally conductive, electrically resistive material disposed on a vessel wall adjacent the conductor. The thermally conductive, electrically resistive material may include an anodized coating or a thin sheet of a plastic, mineral-based material or conductive polymer material. The thermal conductor is fabricated to include a resilient portion which expands and contracts to maintain mechanical contact between the cell and the thermally conductive material in the presence of relative movement between the cell and the wall structure.Type: GrantFiled: July 3, 2000Date of Patent: May 27, 2003Assignees: 3M Innovative Properties Company, Hydro-Quebec CorporationInventors: Roger Rouillard, Michael K.

Patent number: 6548206Abstract: An in-situ thermal management system for an energy storage device. The energy storage device includes a plurality of energy storage cells each being coupled in parallel to common positive and negative connections. Each of the energy storage cells, in accordance with the cell's technology, dimensions, and thermal/electrical properties, is configured to have a ratio of energy content-to-contact surface area such that thermal energy produced by a short-circuit in a particular cell is conducted to a cell adjacent the particular cell so as to prevent the temperature of the particular cell from exceeding a breakdown temperature. In one embodiment, a fuse is coupled in series with each of a number of energy storage cells. The fuses are activated by a current spike capacitively produced by a cell upon occurrence of a short-circuit in the cell, thereby electrically isolating the short-circuited cell from the common positive and negative connections.Type: GrantFiled: June 2, 2000Date of Patent: April 15, 2003Assignees: 3M Innovative Properties Company, Hydo-Quebec CorporationInventors: Michel Gauthier, Michael K.

Patent number: 6296467Abstract: A vibrating screed for surfacing concrete comprises a surfacing blade, a pair of handle assemblies mounted to said blade, a motor, vibration causing mechanism and a transmission connecting the motor to the vibration causing mechanism such that, when the motor is in operation it causes the transmission to rotate with the transmission being adapted to impart a vibratory motion to the blade. The transmission includes a flexible joint having an angled configuration to allow the motor to be mounted rearwardly of a leading edge of the blade. Each handle assembly comprises a main elongated tubular member and a handle mounted at a proximal end thereof. The handle includes a first tubular element mounted around the main tubular member, a second tubular element extending sideways from the first element and a third tubular element extending around the second element, with a grip member being mounted to the third element.Type: GrantFiled: February 16, 1999Date of Patent: October 2, 2001Assignee: Les Betons Roger Rouillard Inc.Inventor: Roger Rouillard

Patent number: 6117584Abstract: A thermal conductor for use with an electrochemical energy storage device is disclosed. The thermal conductor is attached to one or both of the anode and cathode contacts of an electrochemical cell. A resilient portion of the conductor varies in height or position to maintain contact between the conductor and an adjacent wall structure of a containment vessel in response to relative movement between the conductor and the wall structure.

Patent number: 4848961Abstract: The present invention relates to a concrete screeding apparatus, and more particularly to an improved portable and lightweight vibrating concrete screed enabling a workman to use same without the need for rigid forms. The screeding apparatus comprises a generally elongated beam having a horizontal surface and a generally vertical surface. A plurality of vibrators are mounted on the beam. The height of the vertical surface diminishes from the center to the edges so as to increase the amplitude of vibration and, therefore, improve the manoeuverability of the screed. In addition, the corners formed by the trailing edge and the side edges of the horizontal surface are rounded so as to avoid the penetration of the side edges into the freshly poured concrete.Type: GrantFiled: January 11, 1988Date of Patent: July 18, 1989Inventor: Roger Rouillard
