| 20080220318 | Inherently safe redox flow battery storage system - An improved redox battery energy storage system is disclosed for reducing oxygen gas levels and separating oxygen gas from hydrogen gas, thus reducing the likelihood of flammable gas explosions. The system includes at least one cell, which includes a positive compartment having positive solution, a negative compartment having negative solution, and a membrane separating the positive and negative compartments. A positive reservoir is in fluid communication with the cell's positive compartment, the positive reservoir defining a positive vent space for positive gas, which includes oxygen. A negative reservoir is in fluid communication with the cell's negative compartment, the negative reservoir defining a negative vent space. A return line is in fluid communication with the negative compartment and the negative reservoir to return the negative solution from the cell to the negative reservoir through the negative vent space. A positive gas draw line is in fluid communication with the positive vent space and coupled to the return line at a connection, causing positive gas to be siphoned from the positive vent space into the negative vent space, where the negative solution of the negative reservoir scavenges the oxygen. A balancing line is in fluid communication with the positive and the negative vent spaces to recirculate oxygen-depleted positive gas to the positive vent space. | 09-11-2008 |
| 20120017848 | METHOD AND APPARATUS FOR VAPORIZING LIQUID CHLORINE CONTAINING NITROGEN TRICHLORIDE - A method of safely vaporizing liquid chlorine containing high concentrations of nitrogen trichloride contaminant from a chloralkali plant. In a vertical plug-flow vaporizer having an upward flow direction, a stream of liquid chlorine containing nitrogen trichloride is received. A gas such as air, nitrogen or chlorine gas is introduced into the liquid stream upstream of the boiling zone of the vaporizer to induce a flow regime, for example annular flow or mist flow, that prevents a mass accumulation of nitrogen trichloride in the vaporizer. The liquid chlorine containing nitrogen trichloride is vaporized. The resulting gas stream may be processed to destroy the nitrogen trichloride and recycled to the chlorine production train. | 01-26-2012 |
| 20120020866 | METHOD OF PROCESSING LIQUID CHLORINE CONTAINING NITROGEN TRICHLORIDE - A method of processing a stream of liquid chlorine containing nitrogen trichloride from a chloralkali plant. The liquid stream is received into a vaporizer in which it is evaporated 1O1 chlorine gas and nitrogen trichloride gas. The gas stream is processed by destroying the nitrogen trichloride gas, for example in a superheater or a catalytic bed. The processed gas stream is recycled to the chlorine production train of the chloralkali plant. The process avoids the use of organic solvents to decompose the nitrogen trichloride and the creation of a waste stream requiring further handling. | 01-26-2012 |

| 20120032679 | GRADIENT COIL ARRANGEMENT - A gradient coil arrangement for use in a magnetic imaging system, the imaging system being for generating a magnetic imaging field in an imaging region provided in a bore. The coil arrangement includes a first portion having a substantially cylindrical shape for positioning in the bore, a second portion extending outwardly from an end of the first portion, the second portion being for positioning outside the bore and at least one coil for generating a gradient magnetic field in the imaging region, the at least one coil having a first part provided on the first portion and a second part provided on the second portion. | 02-09-2012 |

| 20090249738 | Toggle pin - A toggle pin comprising an elongate main body portion having two ends, one end being provided with a passageway that extends at least partially through the main body portion and which is open at the one end such that a line member can pass into the passageway and be connected to the toggle pin, the other end being provided with a toggle plate, the toggle plate being pivoted to the main body portion in such a manner that the toggle plate can move between an unlocking position where the toggle plate is substantially in line with the main body portion, and a locking position where the toggle plate is substantially at right angles to the main body portion. | 10-08-2009 |

| 20100171468 | CHARGER PROTECTION CIRCUITRY - The present invention provides charger protection circuitry for a rechargeable battery, and a method of protecting a charger cable during charging of a rechargeable battery. A switch controller is used to turn a switch element on and off in dependence on a direction of current flow through the charger protection circuitry during charging and otherwise. If current is flowing in the first direction the switch controller turns on the switch element such that the auxiliary current tripping element is bypassed, whereby the main current tripping element controls interruption of current flow. If instead current is flowing in a second direction opposite to the first direction, the switch controller turns off the switch element, whereby the auxiliary current tripping element is connected into the current flow path to control interruption of current flow. | 07-08-2010 |
