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. Hagen, Orlin B. Knudson, André Morin, Michel Ranger, Guy Ross, Roger Rouillard, Philippe St-Germain, Anthony Sudano, Thomas A. Turgeon

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: 6015106Abstract: Apparatus controllably breaks hollow spheres stored in an enclosure. A first screen is disposed within the enclosure on a screen support. The screen has holes that are no larger in mesh size than the smallest hollow spheres. The screen support provides support to the first screen and has void areas to allow debris from broken spheres to pass through. An impeller is in contact with the first screen such that movement of the impeller across the first screen breaks the hollow spheres in contact with the first screen.Type: GrantFiled: September 1, 1998Date of Patent: January 18, 2000Assignee: 3M Innovative Properties CompanyInventors: Thomas A.

Patent number: 5744322Abstract: An apparatus for counting microorganism colonies on at least on disposable microorganism culturing medium having a substantially planar substrate. The apparatus has an imaging system for detecting colonies on the substantially planar substrate, and a holder positioning device for storing and queuing one or more holders, each adapted to support one of the substrates. The positioning device moves the holders sequentially into a predetermined position relative to the imaging system so that images can be obtained. The imaging system cooperates with a counting device for counting the colonies using information from several images provided by the imaging system taken at different times as the positioning device cycles the holders past the predetermined location to be imaged. Suitable holders, and a method of queuing and counting colonies on substrates, are also disclosed.Type: GrantFiled: August 29, 1996Date of Patent: April 28, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventors: Gary E.

Patent number: 5433395Abstract: A tape cartridge having a tape supply reel contained within the cartridge housing. A tape passes through a tape guideway in the cartridge housing and is attached to the tape supply reel on one end and a tape connector on the other end. The cartridge housing contains a single interlock arm pivotally mounted for rotational movement, one end of the arm which is movable into and out of the tape path, while the other end of the arm is movable through a slot in the cartridge housing. The withdrawal of the tape connector from the guideway releases the arm so that a spring can actuate the other end of the arm outwardly into locking engagement within a notch in an external housing.Type: GrantFiled: August 13, 1993Date of Patent: July 18, 1995Assignee: Minnesota Mining and Manufacturing CompanyInventors: Thomas A. Turgeon, Lawrence A. Flor

Patent number: 5165083Abstract: A removable tape cartridge (14) for insertion into a carrier (12) in order to form a two-piece videocassette (10) comprises a housing (30) with a tape reel assembly (32) therein. The tape reel assembly (32) includes a length of tape (64) with a connector (68) at one end which, upon insertion of the cartridge (14), mates with an associated connector (16) in the carrier (12) to establish connection with a take-up reel (20). The tape reel assembly (32) is normally biased downwardly by a spring (56) and is normally constrained against rotation by an internal brake assembly (70-74) responsive to insertion of the cartridge (14) into the carrier (12). The tape connector (68) is releasably secured in proper position for mating engagement with the corresponding connector (16) by one end of an arm (78), the other end of which functions to interlock the tape cartridge (14) and carrier (12) against separation upon withdrawal of the tape.Type: GrantFiled: April 29, 1991Date of Patent: November 17, 1992Assignee: Minnesota Mining and Manufacturing CompanyInventors: Lawrence A.

The tape reel assembly (30) includes a length of tape (56) with a connector (64) at one end which, upon insertion of the cartridge (14), mates with an associated connector (15) in the carrier (12) to establish connection with a tape-up reel (17). The tape reel assembly (30) is supported within the housing (20) for limited floating movement between up and down positions, but is normally biased toward the down position by a hold down ring (74). A clutch (66-70) provides controlled tape slippage within the tape reel assembly (30), which is normally secured against unwinding by a brake assembly (102-116) until the cartridge (14) has been inserted into the carrier (12).Type: GrantFiled: July 29, 1991Date of Patent: June 9, 1992Assignee: Minnesota Mining and Manufacturing CompanyInventors: Jerrold K. Weeks, James E. Skavnak, Thomas A. Turgeon
