Abstract:
An improved electrochemical energy storing device includes a number of thin-film electrochemical cells which are 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 each electrochemical cell, conducts current into and out of the electrochemical cells and also conducts thermal energy between the electrochemical cells and thermally conductive material disposed on a wall structure adjacent the conductors. The wall structure includes electrically resistive material, such as an anodized coating or a thin film of plastic. The thermal conductors are fabricated to include a spring mechanism which expands and contacts to maintain mechanical contact between the electrochemical cells and the thermally conductive material in the presence of relative movement between the electrochemical cells and the wall structure. An active cooling apparatus may be employed external to a hermetically sealed housing containing the electrochemical cells to enhance the transfer of thermal energy into and out of the electrochemical cells. An integrated interconnect board may be disposed within the housing onto which a number of electrical and electro-mechanical components are mounted. Heat generated by the components is conducted from the interconnect board to the housing using the thermal conductors.

Abstract:
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. The electrochemical generator may be disposed in a hermetically sealed housing.
Abstract:
A cartridge adaptor for converting a cartridge for use in a conventional video cassette machine. The adaptor has a motor to move tape connection structures onto the take-up reel prior to use in the videotape machine. The motor and associated mechanisms also return the tape to the cartridge at the conclusion of use.
Abstract:
A removable tape cartridge (14) for insertion into a carrier (12) in order to form a two-piece videocassette (10) comprises a housing (20) with a tape reel assembly (30) therein. 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).
Abstract:
A carrier for use with a magnetic tape cartridge is disclosed. The carrier includes a manual advance mechanism to advance the tape media onto the take-up reel located within the tape carrier.
Abstract:
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.
