Title: Process for the separation and recovery of fluorochemicals from a gas stream containing a diluent gas and fluorochemicals
Inventor: CHERNYAKOV IOSIF
IPC: F25J3/02
Filed: 1999-04-26
Granted: 2001-06-23
Abstract: A method for the separation and recovery of fluorochemicals from a gas stream containing a diluent gas and fluorochemicals by first contacting the gas stream with a membrane system in one or more stages where the membrane(s) is selectively more permeable to the diluent gas than the fluorochemicals to result in a permeate stream rich in diluent gas and retentate rich in fluorochemicals, thereafter subjecting retentate the gas stream to a purification by distillation or adsorption resulting in a product stream enriched in fluorochemicals and a purified diluent stream. The purified diluent stream is used as a purge stream and/or a recycle stream together with the permeate stream to a vacuum pump upstream of the membrane separation step. A product stream can be produced from a similar gas stream containing diluent gas and fluorochemical by an adsorption step combined with a subsequent distillation step where the purified diluent from the adsorption step is used as a purge stream and/or wholly or partial combined with a purified diluent stream from the distillation step as a recycle stream introduced into the process upstream of the adsorption step. Enriched fluorochemical and an enriched diluent streams can be produced from a stream containing diluent gas and fluorochemicals by cryogenic distillation with the enriched diluent stream recycled to the process upstream of the distillation step.

Title: Method for forming aluminum or copper alloy artistic fork tubes
Inventor: TZENG SHAU-CHIAN
IPC: B21D53/86
Filed: 1999-05-05
Granted: 2001-04-11
Abstract: Disclosed is a method for forming aluminum or copper alloy artistic fork tubes, comprising the steps of: selecting an extruded material; milling the material into an extruded blank; forging and expanding the primary tube; and forging the secondary tube into a fork configuration, so as to accomplish the procedures for forming an aluminum or copper alloy fork tube. The selected extruded material must be equipped with plural apertures and projections. During the milling process, the plural apertures are milled into a configuration with a primary opening at an end and a secondary opening at the other end. The plural projections are milled to be distributed to the raised portion of the primary tube and the raised portions of the secondary tube so as to form the extruded blank. A mold core must be placed in the primary tube opening of the extruded blank to facilitate pressure being applied to the raised portion of the primary tube during the process of forging and expanding, so as to make the primary tube opening into the required expanded configuration. A secondary core must be placed in the secondary tube opening so as to facilitate pressure being applied to the raised portion of the secondary tube during the process of forging the secondary tube to form the fork configuration with bifurcated tubes. As such, for a tube of high rigidity and artistic configuration can be made so as to enhance the forging and forming techniques for making artistic fork tube of non-ferric metals.

Title: Low complexity random codebook structure
Inventor: THYSSEN JES
IPC: G10L19/10
Filed: 1999-08-21
Granted: 2001-06-16
Abstract: A multi-rate speech codec supports a plurality of encoding bit rate modes by adaptively selecting encoding bit rate modes to match communication channel restrictions. In higher bit rate encoding modes, an accurate representation of speech through CELP (code excited linear prediction) and other associated modeling parameters are generated for higher quality decoding and reproduction. To achieve high quality in lower bit rate encoding modes, the speech encoder departs from the strict waveform matching criteria of regular CELP coders and strives to identify significant perceptual features of the input signal. The encoder generates pluralities of codevectors from a single, normalized codevector by shifting or other rearrangement. As a result, searching speeds are enhanced, and the physical size of a codebook built from such codevectors is greatly reduced.

Title: Method for addressing a bitstream to be recorded or being recorded on a storage medium
Inventor: SCHILLER HARALD
IPC: H04N7/24
Filed: 1999-08-27
Granted: 2001-11-11
Abstract: In bitstream recording presentation data is organised into video object units. These have a variable size but have also a variable duration. To allow access to any video object unit in the bitstream a mapping list is used which is based on pieces (SOBU#n) of the bitstream of constant size per piece. The mapping list additionally contains for each of these pieces a specific delta duration (IAPAT#n) which indicates the difference between the arrival time of the first packet of a piece and the arrival time of the packet following immediately the last packet of that piece, and contains an initialisation value (IAPAT#0) which allows to have a share of equal bits between a predetermined amount of MSBs of application time stamps (ATS) and the same amount of LSBs of the summation of said delta time durations (IAPAT#n). The computation of the target SOBU address includes the following steps: (1) accumulate the initialisation value and the delta durations until the given time value is most closely reached towards the target SOBU; (2) the running index of this table entry multiplied by the constant piece size directly results in the address value to be accessed.

IPC: A61M5/32
Filed: 2000-01-21
Granted: 2001-07-11
Abstract: A solid blunt and a needle assembly having a solid blunt. The solid blunt helps to prevent accidental needle sticks. In one exemplary embodiment, a solid blunt has an outer dimension (e.g. outer diameter) which is nearly equal to an inner dimension (e.g. inner diameter) of a cannula of a needle which is configured to contain the solid blunt. In one example, the solid blunt substantially blocks fluid flow in a first circumferential portion of an inner diameter of the cannula and allows fluid flow in a second circumferential portion of the inner diameter. The solid blunt is typically capable of longitudinal movement through the cannula and is prevented from moving substantially in a direction perpendicular to the longitudinal movement. A needle assembly, in another exemplary embodiment, includes a solid blunt, a cannula and a clip which couples slidably the solid blunt to a frame which is coupled to the cannula. The present invention may be used with medical devices including needles, introducers and catheters and other devices as well.
