IPC: G01S13/90
Filed: 1995-08-04
Granted: 1997-10-07
Abstract: In connection with a method for image generation by means of two-dimensional data processing, received SAR data are multiplied by a phase correction (HmC)  for a reference range (rref) for the insertion of a motion compensation and for processing at a high drift angle, and an additional cubic phase term is inserted for compensating a range migration. The entire range migration is then eliminated by means of an additional linear frequency displacement; subsequently the SAR data are transformed back into the "range-Doppler" domain. A remaining  phase  error,  created  by  a  "chirp  scaling" correction, is corrected, the SAR data are transformed back into the time domain and a phase correction as a function of the range is performed by multiplication for the exact motion compensation in the time domain. The one-dimensional reference function is performed in the frequency domain for azimuth compression, by means of which two-dimensional SAR data are obtained.

Abstract: In a recording medium having a porous ink-receiving layer containing alumina hydrate of boehmite structure formed on a base material, the alumina hydrate has crystallinity ranging from 15 to 80 and microcrystals of the alumina hydrate are directed to be parallel to a plane direction of the ink-receiving layer at a parallelization degree of not less than 1.5.          The recording medium is employed in an ink-jet recording method conducting printing by ejecting ink droplets through an orifice onto a recording medium as the recording medium.       A process for producing the recording medium comprises the steps of: applying a coating liquid containing alumina hydrate of boehmite structure with shearing stress onto a base material; and drying the coated material to obtain a degree of parallelization of a microcrystal of the alumina hydrate with a plane direction of the ink-receiving layer of not less than 1.5.

Filed: 1995-12-07
Granted: 2002-02-26
Abstract: A process for making organic slow release nitrogenous fertilizers from pyrolysis products obtained from the pyrolysis of biomass uses a chemical reaction to combine a nitrogen compound containing the -NH2 group with the pyrolysis products to form a mixture.  The mixture is heated to form organic nitrogen compounds.  Various sources of biomass can be used.  The mixture can be heated to remove water and to cause polymerization and solidification to occur. The mixture can also be combined with an absorbent. Previously, nitrogenous fertilizers had been produced using an ammoxidation process requiring long reaction times of up to several hours.

Title: Subtitling transmission system
Inventor: VAN DER MEER JAN
IPC: H04N21/434
Filed: 1995-12-12
Granted: 2011-08-02
Abstract: A method of simultaneously transmitting a video signal and encoded data representing graphic images is disclosed. The invention is particularly applicable for transmitting multilingual subtitles with a video program. The graphic images are rectangular regions within the active video area. They are transmitted in the form of bitmaps. The invention not only allows any character font or size to be displayed, but also the definition of e.g. a program provider's logo. The encoded data includes a time stamp to specify the time at which a subtitle is to be displayed. Preferred embodiments of the invention include the transmission of colour-look-up-table (CLUT) data and a compatibility code indicating a required minimum number of entries of said colour-look-up-table. For receivers with a CLUT having more entries than necessary, a map table is transmitted for mapping the pixel data width to the input width of the relevant CLUT. The method is applicable to Direct Video Broadcast systems wherein the video signal is MPEG2 encoded and the graphic images are accommodated in a private data stream of an MPEG2 Transport Stream.

Abstract: A flexible plunger apparatus includes an elongated flexible member having a pair of opposite end portions and a longitudinal length extending between the opposite end portions, with the flexible member being adapted to flex in transverse relationship to its length and to undergo free movement through a hollow tubing of a well. The apparatus also includes a physical barrier producing mechanism attached to and extending between the opposite end portions of the flexible member for substantially separating gas under pressure in the tubing below the lower end portion of the flexible member from a slug of liquid in the tubing above the upper end portion of the flexible member. The physically barrier producing mechanism is carried along the interior surface of the tubing in a substantially sealing relationship therewith as the flexible member undergoes free movement through the tubing of the well in response to the pressure of the gas and opening of the tubing of the well at the earth surface. The transverse flexibility of the flexible member adapts the apparatus to move through hollow tubing which has an angular, helical or wavy curvature.

Inventor: KIRCHNER EDUARD
IPC: B23K9/00

Granted: 2006-08-29
Abstract: The device proposed is designed to weld together at least two parts (1, 2) using arc-welding or resistance-welding, in particular pressure arc-welding, techniques. An arc is struck across a gap between the two parts (1 and 2), thus causing them to melt. In oder to ensure a very precisely defined vertical gap between the parts, the second part (2) is first placed on the first. The final position, determined by a programme-control unit (12), is measured by means of a travel-measurement instrument (10). Starting from this "zero position", the bolt is lifted through a freely programmable distance and the main welding current activated. On expiry of the prescribed period of time, the bolt on the second part (2) is moved towards the first part (1), this movement also being carried out under programme control.

Granted: 2000-05-30
Abstract: A speech processor uses a plurality of speech processing features to enhance the quality of speech signals received by a user during a telephone call.  The activation of a second speech processing feature is delayed for a time duration measured after the initiation of a particular call or measured after the activation of a first speech processing feature.  This delay eliminates any interference between the second speech processing feature and the first speech processing feature that is active when the call is initiated.  The delay also increases the time it takes for the speech processing features to become fully effective, thus making the enhancement in the quality of the speech signals more noticeable to the user. Further, an optionally generated audio indicator is provided when the second speech processing feature is applied so that the additional feature is even more noticeable to the user.

Abstract: Contaminants are detected at concentrations below 1 part-per-million and extending to a level approaching 1 part-per-trillion by using intracavity laser spectroscopy (ILS) techniques. An optically-pumped solid-state (ILS laser) (500) is employed as a detector. The ILS laser (500) comprises an ion- doped crystal (507) in a laser cavity (902) optically pumped by a pumping source (100). A gas sample containing gaseous contaminant species is placed inside the laser cavity (902) on one side of crystal (507). The ILS laser output signal is detected and analyzed to identify the gaseous species (via its spectral signature). Gaseous species concentration can also be determined from the spectral signature. In one embodiment, the ILS laser (500) comprises an ion-doped crystal medium (507) which is pumped by a semiconductor diode laser. In another embodiment, the ILS laser (500) comprises an ion-doped crystal medium (507) in a linear cavity (902).

Abstract: A process is set forth for the cryogenic distillation of an air feed to produce nitrogen, particularly high pressure nitrogen of various purity, varying from low purity (up to 98% nitrogen) to ultra-high purity (less than 1 part per billion of oxygen).  The nitrogen may be produced at two different pressures and two different purities.  The process used an auxiliary low pressure separation zone in addition to the conventional high pressure column and low pressure column.  The auxiliary low pressure separation zone, which is operated at the same pressure as the low pressure column and which is heat integrated with the top of the high pressure column by means of its bottom reboiler/condenser, pretreats the crude liquid oxygen from the bottom of the high pressure column.
