Abstract: Sorbent compositions for the removal of sulfur and sulfur compounds, such as hydrogen sulfide, carbonyl sulfide and mercaptans, out of cracked gasoline and diesel fuels are prepared by impregnation of a sorbent support containing zinc oxide, expanded perlite and alumina with a promotor metal, such as nickel and/or cobalt, followed by reduction of the valence of the promotor metal. The use of milled expanded perlite in forming the sorbent support results in a support in which the zinc oxide content and binder content could be adjusted to provide an attrition resistant sorbent and extend the useful life of the sorbent.

Abstract: When an ignition system is installed, the spatial position of an ignition device (5a to 5g) in relation to the surrounding, its geographical position, is as yet not determined. The user is required to exercise extreme caution i n order to ensure that the ignition devices (5a to 5g) connect to the ignition system (1) in accordance with a predetermined blasting plan. A specially trained person must therefore systematically carry out the sequential connection (compulsory sequence) of each ignition device (5a to 5g) to the b us line (3) of the ignition system, i.e. logging. The person connecting the ignition devices must execute the ignition of device programming operation i n all kinds of conditions, in open country, with utmost caution. This represen ts a considerable time delay for a blast. If one ignition device is overlooked during logging, the already entered data have to be reprogrammed, which cost s time. The invention provides that the geographical position (4a to 4e, 4f', 4g) of an ignition device (5a to 5g) is determined using a satellite-assiste d navigation system (GPS) (10) and this position is conveyed to the logger (2) .

Title: Controlled pressure drop filter
Inventor: WITTRISCH CHRISTIAN
IPC: E21B43/08
Filed: 2003-10-07
Granted: 2011-07-05
Abstract: A filter (9) is enclosed in and centred on a base tube (1) by longitudinal spacers (14). These are placed around the diameter of the tube to cut the annular space between the filter and the tube into sectors. Collection tubes (5) are arranged in the sectors and open at one end into the sectors.  The spacers contain openings (16, 17) so they interconnect hydraulically. The annular space between the base tube and the filter is closed at its two ends by rings (4). The collection tubes are fixed one one side of a ring so the internal pipe of each collection tube communicates with the other face of the ring. The ring contains means of closing the holes. The annular space is closed at its two ends by rings carrying the collection tubes. The openings in the base tube allow an effluent to flow inside the tube after passing through the filter and the collection tubes, and a sliding sleeve inside the base tube is designed to close the openings.

Granted: 2008-09-23
Abstract: An apparatus and method perform speech signal compression by variable rate coding of frames of digitized speech samples. The level of speech activity for each frame of digitized speech samples is determined and an output data packet rate is selected from a set of rates based upon the determined level of frame speech activity. Errors are masked in frames of data by providing an indication of a frame abnormality in a current frame. Data is stored of at least one previous frame and the stored data is provided in response to the indication of a frame abnormality. The indication of a frame abnormality is responded to by processing the stored data to reduce values represented thereby. A new frame of data is then produced from the processed data for use as the current frame of data.

Granted: 2012-10-02
Abstract: A probe for application to a selected area of a subject's skin covering a body part, which selected area serves as a measurement site for measuring changes in the pulsatile arterial blood volume thereat, includes: a base for application to the selected area of the subject's skin at the measurement site; a pressure applicator for applying a static pressure to the subject's skin at the measurement site; and a sensor for sensing changes in the pulsatile arterial blood volume at the measurement site. The pressure applicator is designed to apply to the measurement site a static pressure of a magnitude to partially unload the wall tension of, but not to occlude, the arteries. The pressure applicator is configured to substantially prevent venous distention and blood pooling at the measurement site by permitting free venous drainage through tissues surrounding the measurement site. This is done by configuring the pressure applicator to apply the static pressure to a relatively restricted area of the subject's skin, which area occupies a relatively small fraction of the surface perimeter of the respective body part at the measurement site, to thereby permit free venous drainage from the measurement site via a wide region of unrestricted passageways surrounding the measurement site.

Title: Methods and apparatus for utilizing user software to communicate with network-resident services
Inventor: ZAVE PAMELA
IPC: H04L29/10
Filed: 2005-01-26
Granted: 2009-03-24
Abstract: Popular operating systems for user devices, such as personal computers (PCs), PDAs, pocketPCs, smartphones, and similar such personal devices, typically come bundled with software that is already installed, maintained and run on a user's computer, namely, a non-specialized HTTP client/web browser and a non-specialized instant messaging client. A device is described which presents a user's instant messaging client and HTTP client/web browser as a unified device for handling real-time user interactions with a network resident application. Since this device represents a network application's interface to a user it is termed a pseudodevice. The pseudodevice, which interfaces with network application software, formats user queries as hyperlinked instant messages that are then sent to the user. The user responds by clicking on a hyperlinked message, which invokes the user's web browser and causes the browser to convey the response as an HTTP request back to the pseudodevice. The pseudodevice adapts communication to the user device depending upon the HTTP requests it receives.

Abstract: Several embodiments of the present invention employ synchronization adapters for synchronizing information between "WinFS" and non-"WinFS" data sources (Figure 36, 3622/3666). Examples of adapters include an adapter that synchronizes address book information between a "WinFS" contacts folder and a non-WinFS mailbox (Figure 36, 3642). In these instances, adapter developers might use the "WinFS" synchronization core services API described herein for accessing services provided by the "WinFS" (Figure 36, 3612) synchronization platform in order to develop schema transformation code between the "WinFS"  (Figure 36, 3612) schema and the non-"WinFS" data source schema (Figure 36, 3624). Additionally, the adapter developer provides protocol support for communicating changes with the non-"WinFS" data source. A synchronization adapter (Figure 36, 3662) is invoked and controlled by using the synchronization controller API and reports progress and errors using this API  (Figure 36, 3652).
