Title: Polymer-lipid microencapsulated gases for use as imaging agents.
Inventor: BERNSTEIN HOWARD
IPC: A61K49/22
Filed: 1997-03-03
Abstract: It has been discovered that the incorporation of gases, especially fluorinated gases such as perfluorocarbons, into microparticles formed from the combination of a natural or synthetic polymer and lipid have significantly enhanced echogenicity as compared with microparticles not including the lipid. Compounds other than lipids which are hydrophobic and limit the penetration and/or uptake of water into the microparticles can also be incorporated into the microparticles to enhance echogenicity. In the preferred embodiment, the polymers are synthetic biodegradable polymers. The microparticles are manufactured with a diameter suitable for the targeted tissue to be imaged, for example, with a diameter of between 0.5 and 8 microns for intravascular administration, and a diameter of between 0.5 and 5 mm for oral administration for imaging of the gastrointestinal tract or other lumens. Preferred polymers are polyhydroxy acids such as polylactic acid-co-glycolic acid, most preferably conjugated to polyethylene glycol or other materials inhibiting uptake by the reticuloendothelial system (RES). The most preferred lipids are phospholipids, preferably dipalmitoylphosphatidylcholine (DPPC), distearoylphosphatidylcholine (DSPC), diarachidoylphosphatidylcholine (DAPC), dibehenoylphosphatidylcholine (DBPC), ditricosanoylphosphatidylcholine, dilignoceroylphatidylcholine (DLPC), incorporated at a ratio of between 0.01-30 (w lipid/w polymer), most preferably between 0.1-10 (w lipid/w polymer). Microparticles for imaging using other detectable agents can be similarly manufactured.

Title: Multi-hulled vessel of variable width
Inventor: BULLMER ERNST
IPC: B63B1/12
Filed: 1998-10-07
Abstract: A multi-hulled vessel of variable width is disclosed, in which two floats (1, 2) are connected with one another by means of a variable connection device (4). By means of the connection device, the distance between the floats can be varied. At the maximum distance between them, the vessel features optimum seaworthiness, while at the minimum distance between them it has a small berthing space requirement. The connection device (4) supports the central unit (3), which encompasses a useful area unit (5). The floats (1, 2) do not have a continuous deck height over their entire length, but feature recesses (120, 220). These recesses (120, 220) are pushed beneath the useful area unit (5) when the floats are adjusted to their minimum interval spacing.

Title: Connection management method for devices connected by digital interface and command structure therefor
Inventor: PARK JONG-WOOK
IPC: H04L29/08
Filed: 2000-07-21
Granted: 2003-01-08
Abstract: The invention provides a connection management method for devices connected by a digital interface, e.g. the IEEE 1394 standard, using a predetermined data format, e.g. IEC 61883. A controller 300 establishes connection between two or more devices 100, 200 and is informed by the devices of any changes in the status of the connection, e.g. a change in the transmitter/receiver device or a change in the number of devices involved in the connection. The connection is controlled in response to the reported changes. For example, if a receiver indicates that it no longer wishes to receive information from a transmitter, the appropriate connection is broken. The controller transmits connection management commands (fig. 4) to the devices comprising bit fields that represent various parameters of the connection, e.g. bandwidth. The devices respond specifying changes in the bit fields. Alternatively, a transmitter may notify a receiver of any changes or vice versa. Preferably the command structure complies with the form of a notify command of the audio-video/control command transaction set (AV/C - CTS).

Title: Cathodoluminescent display arrangements
Inventor: NIXON RALPH DESMOND
IPC: H01J31/12
Filed: 1983-07-13
Granted: 1986-03-26
Abstract: O A display arrangement utilises a fluorescent screen 3 to provide readily alterable bright displays. The arrangement can provide a fairly large display surface, but can be of very small thickness. It contains electron emissive cathodes 5, and field electrodes 7 positioned closely adjacent to the cathode to control the emission of free electrons. Electrons which are freely emitted are accelerated to a mesh electrode 4 which is held at a modest positive voltage. A fluorescent screen 3 having a positive potential of several thousand volts is positioned closely in front of the mesh electrode. The preferred embodiments of the invention, a number of separate cathodes and/or separate field electrodes are provided, so that selected regions of the screen can be illuminated to provide desired display patterns. Individual regions of the screen can be switched on and off (i.e. rendered bright or dark) by the application of very low switching potentials to the field electrodes and/or the cathodes.

Title: Surveying of boreholes
Inventor: RUSSELL ANTHONY WILLIAM
IPC: G01V3/26
Filed: 1989-05-30
Granted: 1992-01-29
Abstract: A method of deriving the true magnitude of the terrestial magnetic field in the direction of the longitudinal axis of a borehole at a region of the borehole occupied by an instrumentation package equipped with magnetic vector measuring means for measuring the lateral magnetic vectors Bx and By and further equipped with gravitational vector measuring means for measuring each of the three gravitational vectors Gx, Gy, and GZ. The method comprises the steps of performing said measurements of the magnetic vectors and the gravitational vectors and from said vector measurements solving the equation:-  Bze = (BVe.Ge - Bx.Gx - By.Gy) / Gz where BVe is the vertical component of the terrestial magnetic field at the location of the borehole, and Ge is the terrestial gravity field. The terrestial gravity field Ge may be derived as the square root of the sum of the individual squares of the individual gravity vectors Gx, Gy and Gz, according to the equation:-  Ge = (Gx<2> + Gy<2> + Gz<2>) <1/2 > . The invention is based on the assumption that the vector measurements, and in particular the lateral magnetic vectors, are substantially uncorrupted by the drillstring or the bottom-hole assembly.
