Inventor: UNRUH JASON M
IPC: B22D17/20
Filed: 2002-08-15
Abstract: A method of producing a semi-solid material without stirring, including heating a metal alloy to form a metallic melt (M), transferring a select amount of the melt (M) into a vessel (80, 200, 300), nucleating the melt (M) by regulating the transferring of the melt (M) into the vessel (80, 200, 300 ), and crystallizing the melt (M) within the vessel (80, 200, 300) by cooling t he melt (M) at a controlled rate to produce a semi-solid material (S) having a microstructure comprising rounded solid particles dispersed in a liquid meta l matrix. In one form of the invention, a temperature-controlled shot sleeve (80) is provided for receiving and cooling an amount of metallic melt (M) at a controlled rate to produce the semi-solid material (S). The shot sleeve (80) has a number of heat transfer zones (102a, 102b) adapted to independently control the temperature of the melt (M) disposed adjacent various portions o f the shot sleeve (80). The shot sleeve (80) also includes a ram (84) operable to discharge the semi-solid material (S) directly into a die mold (90) to fo rm a near-net-shape part.

Abstract: (R) and (S) 2-Aryl-propionic acids, and pharmaceutical compositions that contain them, are useful in inhibiting chemotactic activation of neutrophils (PMN leukocytes) induced by the interaction of Interleukin-8 (IL-8) with CXCR1 and CXCR2 membrane receptors. The acids are used for the prevention and treatment of pathologies deriving from said activation. In particular, the (R) enantiomers of said acids are lacking cyclo-oxygenase inhibition activity and are particularly useful in the treatment of neutrofil-dependent pathologies such as psoriasis, ulcerative colitis, melanoma, chronic obstructive pulmonary disease (COPD),bollous pemphigo, rheumatoid arthritis, idiopathic fibrosis, glomerulonephritis and in the prevention and treatment of damages caused by ischemia and reperfusion.

Title: Method and apparatus for receiving and deshuffling shuffled data in a high-rate packet data telecommunication system
Inventor: KIM MIN-GOO
IPC: H03M13/29
Filed: 2003-09-26
Abstract: A method and apparatus for deshuffling received shuffled data in a communication system supporting multi-level modulation. A transmitter encodes information bits and shuffles code symbols so that systematic symbols having a relatively high priority are disposed at high-transmission reliability positions and parity symbols having a relatively low priority are disposed at low-transmission reliability positionsin a modulation symbol. A receiver demodulates received data and outputs a modulation symbol having a plurality of code symbols, stores the code symbols separately as systematic symbols and parity symbols in corresponding memory areas according to a deshuffling order corresponding to the shuffling, reads the stored code symbols, decodes the stored code symbols at a predetermined code rate, and thus outputs an packet.

Title: Rail road car truck and fittings therefor
Inventor: HEMATIAN JAMAL
IPC: B61F3/00
Filed: 2004-07-08
Abstract: A rail road freight car truck has a truck bolster and a pair of side frames, the truck bolster being mounted transversely relative to the side frames. The mounting interface between the ends of the axles and the sideframe pedestals allows lateral rocking motion of the sideframes in the manner of a swing motion truck. The lateral swinging motion is combined with a longitudinal se lf steering capability. The self steering capability may be obtained by use of a longitudinally oriented rocker that may tend to permit resistance to deflection that is proportional to the weight carried across the interface. The truck may have auxiliary centering elements mounted in the pedestal seats, and tho se auxiliary centering elements may be made of resilient elastomeric material. The truck may also have friction dampers that have a disinclination to stick-slip behaviour. The friction dampers may be provided with brake linings, or similar features, on the face engaging the sideframe columns, on the slop e face, or both. The friction dampers may operate to yield upward and downward friction forces that are no t overly unequal. The friction dampers may be mounted in a four-cornered arrangement at each end o f the truck bolster. The spring groups may include sub-groups of springs of different heights

Title: Suture anchor and approximating device
Inventor: YEUNG JEFFREY E
IPC: A61B19/00
Filed: 2002-12-24
Abstract: An elastically curved suture anchor is resiliently straightened and delivered into tissue by a needle. When the needle is withdrawn, resumption of the curvature provides leverage for anchor rotation as the attached suture is pulled to fasten the anchor within the tissue. A fin at the proximal end of the anchor further increases the rotational leverage and expedites anchor fastening. When two or more anchors with connecting suture are delivered in series on a needle, the tension of the suture helps to draw the anchors together and approximates the pierced tissue.

Filed: 2004-12-15
Abstract: A meter for power lines includes first input channels having AC signals with DC values of about zero. A second input channel has an analog output with a predetermined non-zero DC bias value. Plural biasing and scaling circuits input the AC signals and output corresponding analog outputs. Plural analog-to- digital converters input the corresponding analog outputs and output corresponding digital values. A serial output circuit serially communicates the corresponding digital values for a first set of A/D conversions before serially communicating digital values for a subsequent second set of conversions without providing any synchronization of the corresponding digital values for both the first and second sets of conversions. A serial input circuit serially receives the serially communicated digital values and saves the same in a memory. A processor averages the digital values for the channels and determines whether only the average associated with the second channel has the DC bias value.

Title: Handheld electronic device and keyboard having multiple-function keys
Inventor: FYKE STEVEN HENRY
IPC: G06F1/16
Filed: 2005-02-23
Abstract: An improved handheld electronic device having an improved keyboard provides enhanced usability with fewer keys by enabling the keys to pivot slightly to provide multiple functions to the keys. The improved keyboard may, for example, include internal strips of conductive carbon that are disposed adjacent the keys and are electrically engageable with contacts on a printed circuit board. Specifically, when a key is pressed directly downward it collapses a single dome and connects together a set of primary contacts to provide a first function. When the key is pressed at the side thereof, the key pivots slightly, collapses the dome and connects together the primary contacts, and also engages a carbon strip with a pair of secondary contacts to connect together the secondary contacts, all of which provide a second function. The keyboard may be configured to be of a QWERTY configuration while using only a relatively small number of keys.
