Filed: 1999-02-19
Abstract: <B>"MéTODO PARA FORNECER E MANTER UMA SUPERFìCIE CATALITICAMENTE ATIVA EM UM MOTOR DE COMBUSTãO INTERNA"<D> Uma superfície cataliticamente ativa é fornecida sobre as peças limpas, exposta a combustão de um motor de combustão interna que é "verde", tendo poucas horas de operação, ou é de design moderno, de baixa emissão. Um revestimento de substrato ou barreira térmica de grande área de superfície e preferencialmente capaz de manter uma temperatura de superfície de pelo menos 450° C é depositado na câmara de combustão. Dióxido de zircónio, sílica, ou cinza de óleo lubrificante são adequados. Uma porção cataliticamente ativa tal como platina ou ferro é dispersa em, ou com a superfície de trabalho de combustão do substrato. O ferro em nanofase do ferrocene ou platina em nanofase são adequados. A ação catalítica é mantida pelo fornecimento contínuo de um nível baixo de precursor catalítico ao motor, na carga de combustão.

Title: Extrusion die
Inventor: FELDCAMP EDWARD GEORGE
IPC: B29C48/32
Filed: 2001-03-27
Abstract: An extrusion die comprises a die body surrounding a die cavity 18. The body comprises male portions 24 and female portions 26, the resultant die cavity giving rise to a channel shaped extruded product. The leading edges of the male and female portions are out of alignment such that the normal in use deflection of the die body brings them back into alignment, thereby reducing defects in the end product. This misalignment may be achieved by a variable depth channel 20 machined around the die cavity, or by maintaining a constant depth channel and physically bending one portion of the die body relative to the other. The necessary deflection may be calculated from experimental data or via a finite element analysis of the die.

Title: CDMA receivers with subtractive suppression of interpath interference (IPI) and multiple access interference (MAI)
Inventor: FITTON MICHAEL PHILIP
IPC: H04B1/707
Filed: 2002-01-25
Abstract: Spread spectrum receivers for reducing interference, are described particularly the interference observed at a user-end terminal in a W-CDMA 3G mobile communications system. Interpath interference which arises due to non-zero cross and auto correlation of more than one spreading code is suppressed by estimating a transmitted signal stream for a number of CDMA channels and/or multipaths, respreading this estimated signal and subtracting non-orthogonal interference contributions from a received signal before despreading a desired signal. Alternatively the estimated signal streams can be multiplied by the cross correlation between their spreading code and the desired signal spreading code and subtracted from an already despread symbol. The techniques provide an improved bit error rate or equivalently, enhanced capacity for a digital mobile communications network and is particularly useful for cancelling pilot interference.
