Abstract: A clamping arrangement is provided for compression mounted power electronic devices that is assembled from component parts to form a clamping module. The clamping module provides suitable clamping force to a power electronic device interposed between two heat sink arrangements. The clamping arrangement utilizes clamping beams disposed on either side of the two heat sinks and the interposed power electronic device, elongated members that span and retain each end of each clamping beam against relative movement, and an arrangement for applying a desired clamping force to the heat sinks and the power electronic device. The kit of component parts can be assembled into a clamping module about a power electronic device disposed between two heat sinks and is easily assembled or field disassembled from economical parts. The clamping modules are also adapted to be easily and efficiently combined into an overall stack of modules.

Title: System and method for minimizing slag carryover during the production of steel
Inventor: SHARAN ALOK
IPC: G01J5/00
Filed: 2000-01-13
Granted: 2005-03-22
Abstract: A system and method for detecting molten slag in a tap stream between a steel making vessel such as a basic oxygen furnace (BOF) and corresponding ladle. An infrared (IR) imaging or detecting device (s) is used to image/view the BOF-to-ladle tap stream, the stream transmitting energy indicative of whether molten steel and/or slag is in the stream at a given time.      Gray scale analysis is performed on pixels viewed from the tap stream to determine the number of steel pixels and the number of slag pixels in the stream at a given time. When the ratio or percentage of slag pixels exceeds a predetermined value or amount, an alarm may be actuated to cause an operator to tilt the converter upward to stop tapping, or the converter may be automatically tilted upward to stop tapping.

Title: Wireless mobile call location and delivery for non-geographic numbers using a wireline ssp+scp/wireless hlr interface
Inventor: HOWE WALTER WESLEY
IPC: H04W8/10
Filed: 2000-06-29
Granted: 2009-09-01
Abstract: A system and method is provided for establishing a call to a wireless directory number (982) which is either a non-geographic directory number or a non--dialable directory number. A call is initiated from a wireline telephone (155) to a geographic-based local access directory number (994, 996). An originating switching node (810) recognizes the local access directory number (994, 996) as an AIN trigger, and thereafter identifies a signaling node (820) that is associated with the dialed local access DN (994, 996). The signaling node (820) sends a location request that includes the local access DN (994, 996) to an HLR (130). The HLR (130) obtains the wireless DN (982) from an internal database (990) in which the wireless DN (982) is associated with the local access DN (994, 996). The HLR (130) utilizes the wireless DN (982) to receive a temporary local directory number (TLDN) from visitor location register (140). The HLR (130) associates the TLDN with the local access DN (994, 996) and subsequently forwards the TLDN to the signaling node (820), which in turn relays the TLDN to the originating switching node (810). The call connection is thereafter established directly from the originating switching node in the end office to a visited cellular switch using the TLDN.

Title: Measurement of adherence between a vehicle wheel and the roadway
Inventor: TRAVERT PIERRICK
IPC: G01L5/00
Filed: 2000-08-08
Granted: 2007-10-23
Abstract: A pneumatic tire has two elements on its tread at different distances from the tire axis. The element nearest the axis contains sensor(s) detecting at least a tangential force between the element and a road surface, etc. In normal use of the tire both elements contact the surface; under some operating conditions the first element slides on the surface. Independent claims are included for the following: (a) detecting adhesion between a deformable tire tread and a surface using a tire as above includes producing a signal indicative of the tangential force. Variation in this signal indicates changes in adhesion. The friction between the element and the surface and the potential adhesion between of the tire are calculated; and (b) detecting adhesion between a deformable tire tread and a surface using a tire as above includes producing a signal indicative of the tangential force. A first variation in this signal indicates changes in adhesion. A second variation in the signal as the element contacts the surface is detected. An adhesion limit is determined as a function of the two variations.

Abstract: A two-piece external incontinence device includes a first member, which attaches comfortably and reliably to the urethral meatus of a patient, and a second member. The first member may be secured to the patient's parameatal area by suitable medical grade adhesives.  The second member has a first end, which is dimensioned to be mated with the first member, and a second end, which is dimensioned to be mated with a standard urinary drainage tube or a straight connector or other medical apparatus. Mating of the first member and the second member should be leak-free and reliable, but should insure that, when excessive force is applied by pulling on the standard urinary drainage tube, the first and second members separate to eliminate transference of the force to the patient. These mating pieces also allow intermittent internal catheterization without the loss of the parameatal seal.

Le serveur de données esclave (30) peut recevoir les appels entrants provenant du réseau de télécommunication public commuté (28) via une batterie de modems (50). Le pare-feu protégé (14) restreint le passage des messages provenant de la zone partiellement sécurisée (12) et destinés à la zone sécurisée (10) à ceux qui proviennent directement de la zone partiellement sécurisée (12), mais permet le passage des données de conférence. Ainsi, les parties non autorisées ne peuvent accéder ni au système de réservation (20), ni au serveur de données maître (16). Afin d'établir une conférence, le système de réservation (20) crée une conférence sur le serveur de données maître (16). Celui-ci invite alors les serveurs de données esclaves (30, 32) à se joindre à la conférence, puis lesdits serveurs (30, 32) autorisent les participants à se joindre à ladite conférence.

Filed: 2001-04-20
Granted: 2006-08-15
Abstract: The present invention is directed to a contact center and methodology for servicing non-real-time contacts. The advance time for the non-real-time contacts is determined by subtracting the time of service for an earlier item from the time of service for a later item. Items that are serviced immediately after certain types of predetermined events, e.g.. the queue containing the non-real-time contacts has no working agents; the queue is empty; the system clock is changed; and the system is rebooted are ignored in estimating the wait time for enqueued items. Using this methodology, accurate wait-time predictions are provided for more efficient management of the contact center.

Title: Process for the preparation of ethyl acetate
Inventor: FAWCETT CHRISTOPHER RICHARD
IPC: C07C67/40
Filed: 1999-09-29
Granted: 2007-11-06
Abstract: Ethanol is dehydrogenated in the presence of hydrogen over a dehydrogenation catalyst, for example, a copper on silica catalyst. The liquefiable products present in the resulting intermediate reaction product mixture are selectively hydrogenated over a suitable catalyst, such as 5% ruthenium on carbon, so as selectively to hydrogenate reactive carbonyl-containing by-products to the corresponding alcohols.  Butan-2-one and n-butyraldehyde, which would otherwise cause difficulties in purification of the ethyl acetate product, due to the proximity of their boiling points to that of ethyl acetate, are thereby hydrogenated to 2-butanol and n-butanol respectively. A two stage distillation procedure is then used to purify the selectively hydrogenated product. The first distillation zone is typically operated at less than about 4 bar (4 × 10 5 Pa) absolute, while the second distillation zone is typically operated at a pressure of from about 4 bar (4 × 10 5 Pa) absolute to about 25 bar (2.5 × 10 6 Pa). A first distillate of ethyl acetate, ethanol and water produced in the first distillation zone is redistilled in the second distillation zone, thereby producing a bottom product comprising, typically, from about 99.8 mol % to about 99.95 mol % ethyl acetate and an overhead second distillate, which has a different composition from that produced in the first distillation zone and which is returned to the first distillation zone, preferably at a point above the feed point for the liquefiable products of the selectively hydrogenated reaction product mixture.
