Title: Speech coding apparatus including enhancement layer performing long term prediction
Inventor: SATO KAORU
IPC: G10L19/24
Filed: 2004-04-30
Abstract: Base layer coding section 101 encodes an input signal to obtain base layer coded information. Base layer decoding section 102 decodes the base layer coded information to obtain a base layer decoded signal and long term prediction information (pitch lag). Adding section 103 inverts the polarity of the base layer decoded signal to add to the input signal, and obtains a residual signal. Enhancement layer coding section 104 encodes a long term prediction coefficient calculated using the long term prediction information and the residual signal to obtain enhancement layer coded information. Base layer decoding section 152 decodes the base layer coded information to obtain the base layer decoded signal and long term prediction information. Using the long term prediction information, enhancement layer decoding section 153 decodes the enhancement layer coded information to obtain an enhancement layer decoded signal.  Adding section 154 adds the base layer decoded signal and enhancement layer decoded signal to obtain a speech/sound signal. It is thereby possible to implement scalable coding with small amounts of calculation and coded information.

Title: Self adaptive cement systems
Inventor: LE ROY-DELAGE SYLVAINE
IPC: C04B28/00
Filed: 2004-05-12
Abstract: A self-healing cement system includes cement, water and at least one additive that swells in contact with water from reservoir or from formation in the case of a structural failure in the set cement to provide a physical barrier in the zone of failure. Examples of such material include particles of super-absorbent polymer. These additives have the effect of making the cement self~healing in the event of physical failure or damage such as micro-annuli.  The self healing property is produced by the contact of the water itself, the potential repair mechanism is thus activated if and when needed in case of start of loss of zonal isolation. Several super-absorbent polymers have been identified such as polyacrylamide, modified crosslinked poly(meth)acrylate and non-solute acrylic polymers.

Title: Method of heat drilling of holes in ice and apparatus for carrying out the method
Inventor: DUNKER ERICH
IPC: E21B7/00
Filed: 2004-06-27
Abstract: The major field of application of drilling in ice is polar research with through-bores in floating ice for examining the lower surface of the ice, the water below it and the bottom of the sea. Melt drill heads or wash drill heads operating with hot water are used for heat drilling which, however, can only wash out bore hole diameters in the range of he diameter of the drill and. Therefore, render the lowering and hoisting of drills and measuring apparatus very difficult. For forming uniform and large bore diameters the method in accordance with the invention, therefore, provides a combination of the melt drill and the wash drill, wash drilling taking place in the radial plane of the bore hole, and for this purpose uses a melt-wash drill head (1) which at its top is provided with a water inlet (2), a hemispherical melt section (3) below and a narrow azimuthally circumferential annular gap (5) connected by large surfaces with the water inlet (2), through which gap (5) the hot water (4) is guided against the wall (7) of the bore hole and deflected upwardly so that a smooth surface (14) of the bore hole and a constant bore hole diameter (15) result. The melt-wash drill head (1) closes a pilot bore hole (9) with a film (12) of melt water to prevent cold sea water from being sucked in at the end of the main bore hole (19).
