Title: Neutral-aged hydrophobic organosilicate-modified silica gels
Inventor: BURNS GARY THOMAS
IPC: C09C1/30
Filed: 1998-02-18
Abstract: The present invention is neutral-aged hydrophobic organosilicate-modified silica gels and a method for their preparation. The method comprises three steps, where in the first step an organosilicate-modified silica hydrosol is contacted with a strong mineral acid at a pH  less than 1 to form an organosilicate-modified silica hydrogel. In the second step the organosilicate-modified silica hydrogel is aged at a pH within a range of pH 3.5 to pH 8. In the third step the neutral-aged organosilicate-modified silica hydrogel is contacted with an organosilicon compound in the presence of a catalytic amount of a strong acid to effect hydrophobing of the organosilicate-modified silica hydrogel to form a hydrophobic organosilicate-modified silica hydrogel having a surface area within a range of 100m2/g to 750 m2/g in the dry state. In a preferred process the hydrophobic organosilicate-modified silica hydrogel is contacted with a sufficient quantity of a water-immiscible organic solvent to convert the hydrophobic organosilicate-modified silica hydrogel into a hydrophobic organosilicate-modified silica organogel.

Title: Broadband transmitter for a signal consisting of a plurality of digitally modulated carriers
Inventor: BADA ANNA MARINA
IPC: H04B1/40
Filed: 1998-07-24
Abstract: (57) Abstract It is described a broadband radio transmitter for a digital signal consisting of a plurality of not necessarily equispaced, digitally modulated carriers. The transmitter selects the second replica of the spectrum of the signal coming out from a digital-to-analogue converter DAC to increase the space of the useful signal from the continuous in comparison of the direct use of the base band spectrum would involve. The object of the invention is in fact to obtain a wider transition band and consequently a less stringent local oscillator residue and image filter at radio frequency. To eliminate or reduce the effect of the sin(afTy(aPI function that envelopes the signal coming out from the DAC, the invention foresees the use of an equalization of the analogue type, or the adoption of a zero insertion technique (of the digital or analogue type) or in general a digital x/sinx equalizer. The broadband signal is converted at radio frequency and the image filter selects the lower side band to cancel the spectral inversion made by the DAC if an even order replica is used. The transmitter can be profitably employed in any broadband transmitter application and in any mobile system GSM  900 MHz, or DCS 1800 MHz or UMTS.
