Title: Method and device for producing plastic hollow bodies which are at least partially filled with foamed material
Inventor: MOITZHEIM JURGEN
IPC: B29C44/14
Filed: 2000-06-17
Granted: 2005-04-05
Abstract: The invention relates to a method and device for producing plastic hollow bodies which are at least partially filled with foamed material (54). According to the invention, a blowing mold (22) is firstly used to expand a preform (12) by means of internal overpressure in order to form the hollow body which is then at least partially filled with plastic beads made of foam ed plastic, and the plastic beads undergo an increase in volume inside the holl ow body. To this end, the compressed plastic beads are subsequently introduced, while under a pressure that is greater than the pressure prevailing inside t he hollow body, into the expanded hollow body still located inside the blowing mold. The plastic beads located inside the hollow body are relieved from pressure which leads to an increase in the volumes of the plastic beads, thu s effecting a filling, which is as complete as possible, of at least one delimited partial volume of the hollow body with a plastic foam.

Inventor: CHALABI ACHRAF
IPC: G06F17/27
Filed: 2002-06-14
Granted: 2008-03-11
Abstract: Word sense ambiguity, for "thematic" words in a sentence, is achieved based on thematic prediction. The senses of "thematic" words are disambiguated in a sentence b y determining and weighting possible themes for that sentence. Possible themes are determined for that sentence based on thematic information associated with the different senses of each word in the sentence. A highly deterministic thematic-based word sense disambiguation method is us ed to preprocess the sentence prior to further syntactic and semantic analysis, thereby enhancing accuracy and decreasing the demand for computational resources (memory and CPU) by reduci ng input ambiguities.

Granted: 2009-02-10
Abstract: A performance monitoring method for an optically amplified transmission system. The method provides the optical power at each amplifier site, taking into account the inaccuracies introduced by the SRS in the power estimation obtained with the current methods. An optical spectrum analyzer is used at the output of the transmission link of interest to accurately measure the output power of each wavelength. This value is sent upstream to the last amplifier in the link, to compute an error term as the difference between the actual measurement and the estimation. The error term is used to infer the SRS-induced error by system elements not accounted for in the model. The error term is then fed-back to each amplifier in the link, so that the estimated power is adjusted to account for the SRS-induced inaccuracy.

Title: Valve assembly
Inventor: WRIGLEY ANDREW NICHOLSON
IPC: F16K15/18
Filed: 2004-03-16
Granted: 2008-01-22
Abstract: A valve assembly is designed to avoid or minimise the effect of "compression setting" which occurs when valves control the flow of some hazardous and/or corrosive fluids, especially when at an elevated temperature. The valve assembly includes a valve stem having a head portion which engages with a valve seat in order to close and seal the valve and an elastically deformable portion. In order to allow fluid to flow through the valve, the elastically deformable portion of the valve stem is deformed to allow fluid to pass between the head portion and the valve seat. An additional biasing element such as a cylindrical or conical compression spring is provided to urge the head portion towards contact with the valve seat. In this way, should "compression setting" of the elastic portion of the valve stem take place, the additional spring will ensure that the valve head is still able to be engaged with the valve seat to thereby close the valve.
