Inventor: SPILLMAN DAVID M
IPC: H01M4/38
Filed: 2001-10-23
Abstract: It has been discovered that the connection between a current collector and a molybdenum terminal pin can be improved by roughening the terminal pin. However, a roughened terminal pin detracts from the integrity of the glass-to-metal seal. To overcome this, a sleeve or couple surrounds that portion of the roughened terminal pin that will be sealed to the insulating glass. The sleeve or couple is welded at each end to the terminal pin, and a glass-to-metal seal is formed between the sleeved terminal pin, the insulating glass, and the metallic lid. The resulting assembly contains a portion of the terminal pin that has a roughened surface and is suitable for making a high strength connection to a current collector of a primary or secondary lithium ion battery, and to a sleeved portion which has a relatively smooth surface that provides a high strength for a glass-to-metal seal.

Title: Method and apparatus for operating an electrochemical fuel cell
Inventor: JAMES GREGORY A
IPC: H01M8/04
Filed: 2001-11-28
Abstract: An operating method increases fuel cell life or durability, particularly that of a solid polymer electrolyte fuel cell. The fuel cell has a mean life expectancy that may be empirically determined. The method comprises the step of reversing the direction of flow of at least one of the fluids supplied to the fuel cell (for example, the fuel and/or oxidant reactants) through its corresponding flow field after a time period of operation of the fuel cell. The time period is less than the mean life expectancy of the cell and has a value that is a substantial part of the mean life expectancy. The flow may be reversed once or several times over the life of the fuel cell.      An improved apparatus carries out the method.

Abstract: A hydraulic binder is produced by firing gypsum and then rapid cooling the product from the firing temperature to below 80[deg]C in less than 2 minutes. Production of a hydraulic binder, which is based on natural or artificial calcium sulfate (gypsum, sulfo-gypsum, phospho-gypsum or titano-gypsum) and which contains more than 70% stable and soluble alpha anhydrite (anhydrite-III), is carried out by subjecting gypsum to (a) a firing or soaking step in which the gypsum is heated from ambient temperature to 220-350[deg]C; and (b) rapid cooling to below 80[deg]C in less than 2 minutes to stabilize the alpha anhydrite by fixing of its crystallographic structure. An independent claim is also included for a hydraulic binder acting as an alpha anhydrite based cement and obtained by the above process, the binder containing more than 70% stable and soluble alpha anhydrite.

Title: Back-flushable spiral wound filter and methods of making and using same
Inventor: THOMASON HANS A
IPC: B01D65/02
Filed: 1999-06-22
Abstract: A spiral wound membrane filtration element capable of being back-flushed has a permeate carrier sheet; a permeable membrane filter layer sheet adhesively bonded to the permeate carrier sheet, and a feed spacer sheet. The membrane filter layer sheet folds over the feed spacer so that the feed spacer sheet is sandwiched between two layers of the membrane filter layer sheet. The sandwich positions over the permeate carrier sheet such that the adhesive seal bonds the membrane filter layer sheet to the permeate carrier sheet. The permeate carrier sheet, the membrane filter layer sheet, and the feed spacer sheet are wrapped around a permeate collection tube. The filter element is cleaned by pressurizing the feed solution or by creating a vacuum in the permeate collection tube, and periodically introducing a pressurized back flush fluid into the permeate collection tube of the filtration element to back-flush the membrane, under a pressure and for a time sufficient to dislodge a substantial portion of the retained solids on the surface of the membrane. The membrane filter layer sheet is made by placing a casting solution of a cetain thickness on a passing support substrate having a Frazier air permeability between 0.1 and 10 cfm/ft2. The thickness of the casting solution on the support substrate is controlled through use of a mechanical device for dispensing the casting solution. The substrate with the casting solution is then immersed into a quench bath, to allow removal of casting solution, after an air quench time that allows formation of a thin membrane film on the support substrate.

Abstract: A moineau pump assembly includes a stator with a rotor extending through the stator, the rotor and stator sealingly engaging each other at spaced intervals to form a series of annular spaces. An upstream primary inlet is provided for fluids to enter a first of the series of annular spaces, while a drive unit rotates the rotor.
