Granted: 2003-03-18
Abstract: A fuel-cells system 20 is equipped with an oxygen enrichment unit 34 and supplies air whose oxygen partial pressure has been increased by the oxygen enrichment unit 34 to fuel cells 40 as oxidizing gas. The oxygen enrichment unit 34 is a magnetic oxygen enrichment device that effects oxygen enrichment utilizing the fact that the oxygen molecule is paramagnetic and when magnetized migrates toward a magnetic pole side. Specifically, a magnetic field is generated inside the oxygen enrichment unit 34 by an electromagnet, air compressed by a compressor unit 32 is supplied to the oxygen enrichment unit 34, and compressed oxygen-enriched air is discharged from the vicinity of the magnetic poles in the oxygen enrichment unit 34 and supplied to the fuel cells 40.

Abstract: A wave collector structure (51) for electrical power generation powered by wave energy comprises an outwardly extending and down- wardly depending lip (105, 107) below which is situated a mouth (61, 67) of the collector. The collector further comprises side walls (75, 79) for channelling waves into the collector mouth. These side walls (75, 79) extend horizontally substantially up to or beyond the lip, partially enclos- ing a volume of water between the lip and side walls. The collector is placed in its desired location by sealing the mouth (61, 67) with gates (not shown) and floating the structure to its desired location. Control valves are opened to allow water into the collector to sink the structure to the sea bed (63) whereupon the gates are removed.

Inventor: BARCHUK VLADYMIR
IPC: G01R27/26
Filed: 1999-02-01
Granted: 2006-05-09
Abstract: A capacitor sensor for assessing dielectric properties of currency paper uses a transmitting dielectrode on a first side of an evaluation channel and a receiving electrode on the same first side of the evaluation channel. A passive electrode is located on the opposite side of the evaluation channel and overlays with the transmitting and receiving electrodes. An electronic processing arrangement is connected to the transmitting and receiving electrodes and evaluates the signals for changes in the capacitance coupling of the electrode. This coupling is directly related to the properties of the paper passing between the passive electrode on one side and then transmitting and receiving electrodes on the other side.

Granted: 2007-04-17
Abstract: The ventilator system and method use a isolating heat exchanger to selectively transfer heat between exhaust air leaving an enclosed space and outside air entering the enclosed space. The system operates in three basic modes, under the control of a microprocessor-based controller which is responsive to the temperatures inside and outside of the enclosed space. In the heating mode, heat is transferred from the exhaust air to the outside air when the enclosed space requires heating. In the cooling mode, heat is transferred from the outside air to the exhaust air when the outside air temperature is higher than that in the enclosed space. In the supplemental cooling mode, heat transfer between the exhaust and outside air is reduced or eliminated when the outside air temperature is below the desired temperature in the enclosed space and cooling is required. In the heating mode, the heat exchanger is selectively heated when necessary to defrost it. A by-pass is provided for the introduction of outside air in order to avoid heating of the outside air by the exhaust air during the supplemental cooling mode of operation, and/or provide fresh air to the enclosed space without cooling the heat exchanger while it is being defrosted.

Abstract: A method for restoring or enhancing an environmental resistant coating 22 of a coating total thickness within a coating design thickness range on a metal substrate 20 of an article 10 includes the application of a restoring or enhancing metal 30 to at least one discrete local surface area 28,29. Then at least the discrete local surface area 28,29 is coated with an environmental resistant coating 32. For use of the method to restore a coating 22 on an article which has experienced service operation and the discrete surface area 28,29 includes an undesirable amount of oxidation/corrosion products, the oxidation/corrosion products first are removed from an outer portion 24 of the coating 22 while retaining a coating 22 present at the discrete surface areas 28,29 and retaining the entire coating 22 on surface areas adjacent the discrete surface areas 28,29. Then the restoration metal 30 is applied. For use of the method to enhance an existing coating 22, at least one discrete surface area 28,29 is selected based on an oxidation/corrosion attack pattern 16,18 identified from similar articles 10 which experienced service operation in apparatus of a design for which the article 10 is intended. Then the enhancing metal 30 is applied to the selected area 28,29.
