Abstract: An umbilical cable, particularly adequate for subsea exploration, contains two or more three-phase power supply circuits, each consisting of three conductors grouped in a trefoil configuration, each conductor including a metal core surrounded by an insulating sheath, each conductor being provided with an individual shielding whose cross-section is less than, equal to or greater than that of the core. Advantageously, each insulating sheath may be surrounded by a layer of semiconductor material. Filler spacers made of an insulating material, preferably polyethylene, may be used to aid in the positioning of the trefoils. The cable provides an economy of material, an increased flexibility, a reduction of the diameter of the finished cable and a substantial decrease of manufacturing time as compared with cables produced in accordance with the known art. A manufacturing method for an umbilical cable is also disclosed.

Abstract: For two-dimensional imaging of scenes through continuous passive or active microwave scanning, use is made of a fully mechanized directional antenna array comprising a main reflector (1), a primary radiator array (3) and a subreflector (2) having a small size in comparison to the main reflector and being tilted relative to the optical axis (7) of the directional antenna array. First drive means (8) are operative to rotate the subreflector (2) about the optical axis (7), and second drive means (17,18) are operative to move the total directional antenna array in a direction approximately vertical to the optical axis (7). The moving speed of the subreflector (2) is very high in comparison to that of the total directional antenna array.

Abstract: A multi-layer film, useful as a front sub-assembly in electro-optic displays, comprises, in this order: a light-transmissive electrically-conductive layer (114); a light-transmissive first protective layer (112); a light-transmissive moisture barrier layer (108); and a light-transmissive second protective layer (106). This multi-layer film can be used in forming an electro-optic display by the processes described in U.S. Pat. No. 6,982,179 or Patent Publication No. 2007/0109219.
Abstract: Dual reflector offset mechanical pointing low profile telecommunication antenna, to be used above all on vehicles, even high-speed ones. Its reduced physical dimensions facilitate its use, with respect to the known solutions, as it allows its connecting to the receiving system, such as a satellite, though installed on a train or on an aircraft. The invention lies within the technical field of telecommunications and the applicative field of stationary, movable antennas of reduced dimensions, and accordingly within that of telecommunications in general. The original dual reflector antenna is obtained from a second-order polynomial that configurates it in the Cartesian space XYZ.

Abstract: In order to derive the temperature in the mesopause region from hydroxyl (OH*) airglow, in which intensities of three lines of OH* emission and a basic position are measured during the night using ground-based IR spectrometers, a noisy OH* spectrum is smoothed by filtering out white noise superimposed on the measured OH* intensities, by means of a spectral analysis method in the form of a harmonic analysis and by means of adaptation using the Voigt function which is carried out in the form of a combination of a Lorentz distribution and a Doppler distribution. A decision is made on the quality of the adaptation of the smoothed spectrum obtained to the original spectrum using statistical characteristic variables and by selecting one of the two methods, harmonic analysis function or Voigt function, and the temperature is thus accurately determined.

Abstract: A method for correcting typing errors according to character layout positions on a keyboard which consists of depressing responsive touch panels to do character entry to correct typing errors caused by mistakenly hitting a neighboring key of a targeted character due to a swerved typing position includes at least the steps of: (1) corresponding a character; (2) calculating a swerved amount; (3) selecting a prepared character; (4) determining whether input is finished; (5) judging rules; (6) getting the prepared character; and (7) switching the character. Through this method input accuracy can be improved and input characters can be automatically amended as desired.

Abstract: The invention concerns a method and device for adjusting the fitting depth of a tool in a tool-holder, in particular in a tool-holder to be banded. The method is characterized in that it consists in performing a prior calibration of a sensing assembly (2) by positioning a sensing slide (4) of said assembly (2) into a bore (V) of a calibrating support (1) and by re-setting a viewing means of said sensing assembly (2), then in positioning the sensing assembly above a tool-holder and moving the adjustable stop of said tool-holder towards the sensing slide (4), so as to determine a travel thereof corresponding to the required fitting depth. The invention is applicable in the field of the environment of machine-tools, more particularly comprising tool-holders to be banded.
Abstract: A process is provided for producing glycolic acid from formaldehyde and hydrogen cyanide. More specifically, heat-treated formaldehyde and hydrogen cyanide are reacted to produce glycolonitrile having low concentrations of impurities. The glycolonitrile is subsequently converted to an aqueous solution of ammonium glycolate using an enzyme catalyst having nitrilase activity derived from Acidovorax facilis 72W (ATCC 57746). Glycolic acid is recovered in the form of the acid or salt from the aqueous ammonium glycolate solution using a variety of methods described herein.
