Patent CA-2228636-A1 (CA)
Inventor: KORDSACHIA OTHAR
IPC: C01B15/037
Filed: 1996-07-30
Abstract: Alkaline solutions of hydrogen peroxide or compounds capable of providing peroxide ions are used to bleach cellulose and other fibrous materials in the manufacture of paper. Owing to the transition-metal ions contained at low concentrations in the cellulose fibres, the peroxides undergo homolytic decomposition, thus leading to considerable losses of peroxide and, owing to the reactivity of the oxygen radicals formed, cleavage of the carbohydrate chains. To stabilize such bleach liquors, the method proposed uses, alone or in the form of a mixture, a combination of a type 1 complexing agent consisting of a phosphonate and/or poly-.alpha.-hydroxyacrylic acid and/or an aminopolycarboxylic acid and a type 2 complexing agent consisting of oxy and/or polyoxy compounds with 2 to 7 C-atoms in the carbon chain and/or protein derivatives. This stabilizer is suitable for use in stabilizing alkaline bleaching solution containing oxygen, hydrogen peroxide and/or compounds capable of providing peroxide ions and can be used, under oxygen pressure, under ambient pressure or under hydrostatic pressure, to bleach aqueous fibre suspensions in the manufacture of paper or in the processing of fibrous materials (synthetic fibres) used in the chemical industry. The stabilizer mixture gives an excellent degree of bleaching, at the same time enabling hydrogen peroxide consumption to be significantly reduced, the fibres are damaged much less by the bleach and the stabilizer mixture is more readily biodegradable than type 1 complexing agents.

Patent CA-2232309-A1 (CA)
Inventor: HOCKADAY ROBERT G
IPC: H01M8/10
Filed: 1996-09-12
Abstract: A compact, surface replica fuel cell has a fiber reinforced, porous central membrane (3) and two porous outer membranes (23, 31). Thin film catalyst and metal electrode materials are deposited on both sides of the central membrane, using a variety of techniques, such as ion or light bombardment, etching, and vacuum deposition. For compound fuels, two catalysts are deposited. The first catalyst (13) forms the interior surface replica electrode (9). The second catalyst is positioned on the interior of pores (65) to scavenge hydrogen before it is diffused out of the electrode and the electrolyte (21). A  hydrophobic film (19) is deposited over the electrode films to control electrolyte positioning and to strengthen the electrodes. Catalyst surface active area is maximized by separating the catalyst film from the porous non-electrolyte substrate (45) and filling the voids between the substrate and the catalyst film with electrolyte. A non-bipolar stack of fuel cells is constructed on the central membrane by geometrically engineering the cells on the central membrane to provide through-membrane contacts, through-cell water flow, thin film electrodes and electrode breaks. The fuel cell may function as an electrolysis cell for generating reactant gases from the electrolyte.

Title: Inductively powered battery charger
Inventor: GREEN ANDREW WILLIAM
IPC: H02J17/00
Filed: 1997-05-02
Abstract: Loosely coupled inductive power for charging batteries is rectified from a first power pickup winding and the resulting current source is connected to a battery unit (309). Each current source is controlled by shorting a second resonant winding (304). Battery banks may be charged using multiple isolated position-tolerant pickups independently controlled according to the condition of the connected battery unit and by overall commands communicated over an isolated link. The battery unit may be a single cell. In a self-stabilising bank or monoblock a primary inductive conductor is energised using all the cells, individual cells are separately monitored by control means and any below-average cell can be individually charged from the inductive conductor, thus correcting between-cell variations. The charge in all cells within a bank can be held within (for example) 30 % to 70 % of full charge and prevented from drifting towards full or empty during repetitive charge and discharge times.
Patent CA-2252625-A1 (CA)
Inventor: UEDA HIROSHI
IPC: A61K48/00
Filed: 1998-02-27
Abstract: This invention provides a system for controlling the phenotypic characteristics of cells. A pair of chimeric polypeptides is anchored in the plasma membrane, each of which has a variable region sequence and an effector sequence. The polypeptides are independent in the absence of antigen, but form a stable complex with each other when antigen is provided. This drives the effector sequences together in a manner that produces a receptor activation signal, leading to a phenotypic change. By titrating the amount of antigen present in the environment, the degree of phenotypic change can be regulated.  Cells bearing chimeric polypeptides can be used to measure the concentration of antigen or select cells transfected with a therapeutic gene. The chimeric polypeptides can be used as a switch to turn on and off characteristics such as proliferation, apoptosis, degranulation, and protein synthesis, or to target cytolytic cells to antigen-bearing targets.
