Inventor: HOELTER HEINZ
IPC: E21C45/06
Filed: 2000-02-13
Abstract: The invention relates to a method for extracting methane hydrate on the ocean floor, wherein a tube that is open on both ends is guided into the area of the methane hydrate and high-pressure air is built up in the lower section of the tube, wherein solid methane hydrate is swept along by the strong flow generated in the tube from the bottom upward and substantially thawed as it passes through the tube from the bottom upward. The resulting methane gas fraction is collected on the top section of the tube and stored in appropriate containers for further use.

Title: Method for supporting a discontinuous transmission mode in a base station in a mobile communication system
Inventor: CHANG YONG
IPC: H04J13/00
Filed: 2000-05-12
Abstract: Disclosed is a method for transmitting a signal from a base station transceiver system (BTS) to a base station controller (BSC) when there is no  data transmitted from a mobile station while in discontinuous transmission (DTX) mode, in a mobile communication system. The mobile communication syste m includes a mobile station for transmitting and receiving data in a predetermined period, a base station transceiver system and a base station controller for controlling the base station transceiver system. Upon detecti on of the discontinuous transmission mode, it is determined what type of frame was last transmitted from the mobile station, and the present power control information is set according to the type of frame. If it is a null frame, th e base station transceiver system sets previous power control information that  the base station transceiver system has used for power control of the mobile  station before detection of discontinuous transmission mode, to present powe r control information. Thereafter, the base station transceiver system transmi ts a reverse message including the present power control information to the bas e station controller over a dedicated control channel. If there is data being transmitted between the mobile station and the base station transceiver syst em at the time wherethe discontinuous transmission mode is detected, the previous power control information is set to the present power control information.

Title: Method for purifying a gas stream
Inventor: NAEF URS GEORG
IPC: B01D53/86
Filed: 1999-07-19
Abstract: The invention relates to a method for purifying a gas stream containing impurities composed of organic compounds, said gas stream flowing out of a reactor (1) designed for solid phase condensation, preferably for aromatic polyesters and polyamides. According to said method, a gas containing at least oxygen is fed to the gas stream containing the impurities. The combined gas stream is then conveyed, at a high temperature, especially from 280 ~C to 380 ~C, onto a catalyst (8) containing rhodium or a rhodium alloy on an inert porous support. It was found advantageous that the amount of oxygen used be hypo stoichiometric, in relation to the organic impurities, and/or that the ratio of oxygen to impurities be controlled by means of a lambda probe ().  Such a lambda probe () is used in a facility according to the invention.

Title: Combination air compressor-lifting jack
Inventor: HUNG MICHAEL
IPC: B66F5/04
Filed: 2001-06-07
Abstract: An air compressor capable of being mounted across a lifting jack is disclosed. The air compresssor outer housing has a lower section that has a inverted "u" shape cavity to be mounted across the two vertical side plates of the lifting jack to be combined into a single unit. Therefore the air compressor can be stored, transported or operated.      Within the outer housing of the air compressor, on each side face there is a cavity with a cover for opening and closing. These cavities create storage for the power-cord and hose/connector when not in use.      The top surface inside the inverted "u" section is formed with a sloping angle approximately matching the sloping top edge of the two vertical plates. This allows the air compressor to be clamped in an approximate horizontal inclination for easier operation.

Patent CA-2357100-A1 (CA)
Inventor: PRATT DAVID W
IPC: E21B27/00
Filed: 2001-09-06
Abstract: A bailer has two externally-mounted weights. The first weight is positioned at its uppermost end and the second weight is positioned at its lowermost end. The combination of weights increases the insertion rate of the bailer into a liquid so that the time elapsed for an insertion is reduced relative to the time required to insert unweighted bailers, top-weighted bailers, or bottom-weighted bailers.      The weights also prevent wobble about the longitudinal axis of the bailer as it descends. In a second embodiment, a spacer member is secured to the leading end of the bailer to space the leading end away from a bottom of a well. In this way, sediment stirred up by the impact of the bailer against the bottom of a well does not enter into the hollow interior of the bailer.

Patent CA-2358454-A1 (CA)
Inventor: KIANI MASSI E
IPC: G01N21/35
Filed: 2000-01-25
Abstract: A universal/upgrading pulse oximeter (UPO) (210) comprises a portable unit (610) and a docking station (660, 910) together providing three-instruments-in-one functionality for measuring oxygen saturation and related physiological parameters. The portable unit functions as a handheld pulse oximeter. The combination of the docked portable and the docking station functions as a stand-alone, high-performance pulse oximeter. The portable-docking station combination is also connectable to, and universally compatible with, pulse oximeters from various manufacturers through use of a waveform generator (320, 930). The UPO provides a universal sensor to pulse oximeter interface and a pulse oximeter measurement capability that upgrades the performance of conventional instruments by increasing low perfusion performance and motion artifact immunity, for example. Universal compatibility combined with portability allows the UPO to be transported along with patients transferred between an ambulance and a hospital ER, or between various hospital sites, providing continuous patient monitoring in addition to plug-compatibility and functional upgrading for multiparameter patient monitoring systems. The image on the portable display (264, 740) is rotatable, either manually when undocked or as a function of orientation (950). In one embodiment, the docking station (660) has a web server and network interface (1410) that allows UPO data to be downloaded and viewed as web pages over a local area network (1420) or the Internet.
