Title: Filtering device for diesel engine exhaust gas
Inventor: SAMARAS ZISSIS
IPC: F01N3/027
Filed: 2006-10-30
Abstract: This invention relates to a filtering device for diesel engines based on metal foams. In order to achieve high filtration efficiency with low pressure drop using deep bed filtration metal foams, a radial flow concept is used based on a "porosity gradient". The foams can also be coated with catalytically active material to enhance soot oxidation (regeneration), as well as reduction of other exhaust gas pollutants (CO, hydrocarbons, nitrogen oxides). This may be accomplished by using non-uniform amounts of catalytic materials within the filter depending on the targeted application. An additional secondary filter segment (13) may be placed within the metal support of the main filter segment (8). The metallic diaphragms (11, 12, 16) at the entrance and exit of the external shell (1) are designed in such a way as to allow the flow to be divided between the main (8) and the secondary (13) filter segments according to the respective flow resistances. The filter can be designed in such a way as to ensure very high filtration efficiency when clean and ensure a non-blocking behavior in case the soot loading in the filter reaches extremely high values due to various reasons such as prolonged low temperature operation.

Title: Imaging device and imaging system
Inventor: KIDO TOSHIHITO
IPC: G03B13/12
Filed: 2006-12-12
Abstract: A plurality of exchange lenses designed for object exposure regions of different sizes can be selectively mounted on an imaging device. The imaging device judges whether a mismatch state is present, i.e., whether the size of the object exposure region of the exchange lens mounted is smaller than the size of the imaging region of the imaging element. If it is judged that a mismatch state is present, an image of a part of the imaging region is generated and the image of the partial region is displayed as a live view image in a comparatively large area (an area larger than the area for displaying the partial region at the live view display when no mismatch state is present), thereby displaying a live view of preferable visibility.

Title: Fuel cell system and its operation stop method
Inventor: YOSHIDA NAOHIRO
IPC: H01M8/04
Filed: 2006-11-29
Abstract: Provided is a fuel cell system including a fuel cell (20) having a catalyst layer inside and receiving a reaction gas to generate electricity; and a coolant system (73) for supplying a coolant to the fuel cell to control temperature of the fuel cell. A method for stopping operation of the fuel cell system is also disclosed. If the system is placed under a low temperature environment the fuel cell is frozen and restart is disabled. For this, conventionally, upon stop of the system, the coolant flow rate to the fuel cell is reduced to lower the cooling performance and operation of the fuel cell is continued to increase the temperature of the fuel cell. However, the control may be useless since this is performed regardless of the condition upon the next system start. In order to solve this problem, when the temperature of the fuel cell (20) upon the next system start is estimated to be equal to or below a predetermined temperature, the coolant supply is stopped upon system stop and the coolant supply is resumed after a predetermined time has elapsed.

Title: Autocompletion method and system
Inventor: DI COCCO ANTONIO
IPC: G06F3/048
Filed: 2006-06-16
Abstract: An implementation of an auto-completion or auto-correction mechanism where a dictionary of entry list look-up is triggered by the expiry of a time limit between data entry events such as key-press events, where the value of the time limit is dynamically determined as a function of the entry rate. The time limit may be calculated for example on the basis of an average entry rate, and may include an extra margin value. The occurrence of look up triggering will therefore tend to be optimised to the present user's data entry rate.

Title: Butane absorption system for vent control and ethylene purification
Inventor: MC SWAIN C V
IPC: C07C5/00
Filed: 2007-01-30
Abstract: The present invention describes a n-butane absorption process for purifying the ethylene product from an ethane oxidation process. The ethane oxidation product is fed to a series of absorption towers using a n-butane solvent that remove the inert components as well as purifying the ethylene from the product. A first absorption tower uses n-butane as a solvent to absorb both the ethane and ethylene, allowing for inert gasses to be removed from the stream. An ethylene-rich side stream from this tower is sent to an ethylene purification tower where ethylene is purified using n-butane solvent. The bottom stream from the first absorption tower is then sent to an intermediate ethylene recovery tower where crude ethylene is purified, and the overhead ethylene stream being sent to the ethylene purification tower. The bottoms stream, along with the bottoms stream of the ethylene purification tower, both of which comprise mostly ethane and n-butane, are then sent to a stripper tower for ethane recovery and n-butane solvent recover.
