Title: Improved method for the isolation of nucleic acid
Inventor: VAN GEMEN BOB
IPC: C12Q1/68
Filed: 1999-01-26
Abstract: The present invention relates to a method for isolating nucleic acid from a sample. Known methods for the isolation of nucleic acid from these materials may comprise the use of a chaotropic substance, for example to lyse cells present in the starting material, and free the nucleic acid therefrom. When a nucleic acid containing material is treated with a chaotrope and contacted with a nucleic acid binding solid phase, the nucleic acid will bind to the solid phase in the presence of the chaotrope and the solid phase with the nucleic acid bound thereto can thus be separated from the remainder of the sample. The method of the present invention for the isolation of nucleic acid from nucleic acid containing starting material is a method wherein the starting material is contacted with a chaotropic substance and, either simultaneously or subsequently, with a nucleic acid binding solid phase, where after the nucleic acid binding solid phase is subjected to a washing procedure and, optionally, the nucleic acid is eluted from the nucleic acid binding solid phase, characterized in that the washing procedure comprises the steps of washing the solid phase with subsequently one ore more high salt buffer solution(s), optionally an alcoholic solution and a low salt buffer solution.

Title: Packet-transmitting system
Inventor: WATANABE EIICHI
IPC: H04N21/2362
Filed: 2000-09-18
Abstract: A packet-transmitting system comprising a transmitter and a receiver. In the transmitter, the packet-allocating circuit receives a stream of packets.  The circuit allocates the packets having PIDs a1 to b1 to the transmission channel #1, the packets having PIDs a2 to b2 to the transmission channel #2, and so forth.  The circuit allocates the packets having PIDs a N to b N to the last transmission channel #N. The control-data generating circuit time-divides and multiplexes packet-group data (groups of PIDs) representing the groups of packets to be transmitted via the channels #1 to #N, thereby generating control data to be transmitted through the transmission channel #0. The packets in the channels #0 to #N are multiplexed by a CDM system.  In the receiver, the groups of packets, transmitted via the channels #1 to "N, are recognized from the control data transmitted via the channel #0, and only the signals transmitted via the channel designated by a user are extracted and reproduced. Thus, the receiver can therefore receive only the packet the user desires.

Title: System and method for removing contaminating gases from water
Inventor: PRESCOTT PERRIN T
IPC: B01D19/00
Filed: 2001-02-09
Abstract: The system removes contaminating gases, such as radon, from water using a bubbling action. Contaminated water is sprayed together with air through a duct to a bottom region of a bubbling container. The water and air move generally in the same direction through the system, allowing the flow rate to be varied while maintaining forced air/water contact. The aerated contaminated water bubbles upwardly through the bubbling container and passes through one or more diffusing or mixing plates causing the aerated contaminated water to further break out contaminating gases into the air. At the top region of the bubbling container, the contaminating gases are vented while the decontaminated water flows into a tank. The decontaminated water can then be pumped to a desired location, for example, to a house water system. A control system controls the operation of the system based upon water needs by stopping the introduction of air and water into the system when the decontaminated water in the tank has reached a predetermined level.

Title: Base station identification in orthogonal frequency division multiplexing based spread spectrum multiple access systems
Inventor: VISWANATH PRAMOD
IPC: H04B1/713
Filed: 2001-02-27
Abstract: A base station having the strongest downlink signal is identified by utilizing a unique slope of a pilot tone hopping sequence being transmitted by a base station. Specifically, base station identification is realized by determining the slope of the strongest received pilot signal, i.e., the received pilot signal having the maximum energy. In an embodiment of the invention, the pilot tone hopping sequence is based on a Latin Squares sequence. With a Latin Squares based pilot tone hopping sequence, all a mobile user unit needs is to locate the frequency of the pilot tones at one time because the pilot tone locations at subsequent times can be determined from the slope of the Latin Squares pilot tone hopping sequence. The slope and initial frequency shift of the pilot tone hopping sequence with the strongest received power is determined by employing a unique maximum energy detector. In one embodiment, the slope and initial frequency shift of the pilot signal having the strongest received power is determined by finding the slope and initial frequency shift of a predicted set of pilot tone locations having the maximum received energy. In another embodiment, the frequency shift of the pilot signal with the strongest, i.e., maximum, received power is estimated at each of times "t". These frequency shifts are employed in accordance with a prescribed relationship to determine the unknown slope and the initial frequency shift of the pilot signal.

Abstract: L'invention concerne un système de harnais auto (110) dont la ceinture de torse (101t) comprend une structure gonflable (101) qui se gonfle sous l'effet d'un choc afin de protéger les occupants d'un véhicule tel qu'une voiture. La structure gonflable est reliée à un générateur de gaz (122) et à un détecteur d'impact. Lorsque le détecteur détecte un choc dont la gravité dépasse le niveau prédéterminé, le générateur de gaz s'allume, gonfle la structure gonflable qui se contracte en longueur à mesure qu'elle gonfle. Selon une version préférentielle, la structure gonflable est un tube tressé. A mesure que le tube tressé gonfle, son diamètre augmente considérablement et sa longueur diminue considérablement, en raison de l'orientation des fibres formant le tube. La contraction en longueur précontraint le système de harnais d'auto, éliminant ainsi tout jeu.

Title: Procede aerodynamique permettant de fabriquer du papier de soie
Inventor: DROBOSYUK VIKTOR MIKHAILOVICH
IPC: D21F11/00
Filed: 1999-10-25
Abstract: L'invention concerne un procédé aérodynamique permettant de fabriquer du papier de soie. Ce procédé consiste à préparer un toile de formation, à humidifier la couche de fibres obtenue puis à comprimer et sécher cette couche de fibres. Etant donné que l'humidification de la couche de fibres se fait en même temps que la compression, la couche de fibres est située entre les courroies de profilage et d'humidification. La surface de la courroie de profilage comprend des éléments saillants séparés entre eux par une distance ne dépasse pas la longueur moyenne des fibres. Une bande pourvue de noeuds lisses constitués de fils entrelacés peut servir de courroie de profilage, tandis qu'une bande à mailles fines peut servir de courroie d'humidification. L'humidification sélective des fibres réalisée uniquement sur les zones en cours de compression permet d'éviter l'humidification de toute la couche tandis que le séchage de la bande de papier demande sensiblement moins de temps et d'énergie. Grâce à ce procédé, les zones de la couche fibreuse qui ne sont pas comprimées ne sont pratiquement pas humidifiées, ce qui permet de minimiser le rétrécissement de la bande de papier.
