Title: Method and device for maintaining a concentration of a treatment bath
Inventor: BIEL ROGER
Filed: 2010-10-14
Abstract: There is described a method for maintaining the concentration of a treatment liquid bath in the production process for contact lenses (L) which comprises the process steps of rinsing each lens (L) in a water bath immediately prior to immersing the lens in a liquid bath for extraction and/or rinsing and/or coating thereof.

Title: Integrated electrode separator assemblies for lithium ion batteries
Inventor: SCHMIDHAUSER JOHN
IPC: H01M50/426
Filed: 2013-11-01
Abstract: The invention relates to integrated electrode separators (!ES), and their use in lithium ion batteries as replacements for free standing separators. The !ES results from coating an electrode with a fluoropolymer aqueous-based emulsion or suspension, and drying the coating to produce a tough, porous separator layer on the electrodes. The aqueous fluoropolymer coating may optionally contain dispersed inorganic particles and other additives to improve electrode performance such as higher ionic conduction or higher temperature use. The !ES provides several advantages, including a thinner, more uniform separator layer, and the elimination of a separate batte1y component (separator membrane) for a simpler and cost-saving manufacturing process. The aqueous separator coating can be used in combination with a solvent cast electrode as well as an aqueous cast electrode either in two separate process steps, or in a one-step process.
