Abstract: An intraluminal grafting system having a balloon catheter assembly, a capsule catheter assembly and a capsule jacket assembly is used for deploying a graft having attachment means in the vessel of an animal body. The system contains a proximal capsule means and a distal capsule means, wherein the graft is disposed within the two capsule means and a removable sheath covers the graft and capsule means. The graft is comprised of a tubular member having superior and inferior ends, having attachment means with wall engaging members secured thereto. The balloon catheter is disposed within the capsule catheter to provide relative movement between the balloon catheter and the capsule catheter, whereby the graft can be removed from the capsule means. The balloon is inflated to firmly implant the graft and attachment means within the vessel. The graft and attachment means remain in the vessel after the intraluminal grafting system in withdrawn.

Abstract: The present invention relates to a method of upgrading a tank or a method which involves the assembly of an inner tank within an existing outer tank. In the method of the present invention, rolled panel sections are inserted through a hole of an existing outer tank. The rolled panel sections are adjacently positioned within the existing outer tank and expanded so as to conform to the shape of the existing outer tank. End cap sections either flat or domed depending on the shape of the outer tank are also installed through the hole. All of the seams (axial and transverse) are sealed so as to provide for an inner tank within the outer tank that can rate as a stand-alone tank. Circumferential ribs are installed and attached along a length of the inner tank so as to provide for a structural rigidity of the inner tank. With the method of the present invention it is not necessary to completely replace an existing tank and at the same time, if the outer tank has structural weaknesses, the tank can be strengthened by the formation of the inner tank utilizing the method of the present invention.

Title: System and method for performing inversion on lwd resistivity logs with enhanced resolution
Inventor: ILLFELDER HERBERT MAX JOSEPH
IPC: G01V3/38
Filed: 1997-03-11
Abstract: An improved system and method for performing inversion and for correcting for shoulder bed effect. The method enhances the resolution of wave propagation resistivity logs and corrects the logs for adjacent bed effects, whereby the resulting logs have a vertical response as good as wireline high-resolution induction logs. The method first performs logging while drilling on a formation to obtain LWD resistivity log data. The method then selects one or more control depths at one or more locations of each of a plurality of detected beds in the formation. The present invention includes a novel method for selecting bed boundaries from the log data, and the control depths are then determined based on the determined bed boundaries. 1'he method then estimates the resistivity of each bed only at the selected control depths to produce an estimated resistivity of the beds. The method then computes a simulated log value at each control depth using a current estimate of the resistivity of the beds. The computed simulated log is then compared to the actual log data at each control depth, and the resistivity of each bed is adjusted using the difference between the actual and simulated values at the control depths. The above method iteratively repeats a plurality of times until the simulated log substantially matches the actual log at the control depths. The method for determining the bed boundaries in the formation preferably comprises fitting a cubic polynomial in depth to the conductivity, or log of the conductivity, using a weighted linear least-squares method. The curve fit of the log data is performed a plurality of times on portions of the log data using a windowing method. This windowing method comprises moving a window across the log data at periodic increments, and performing the curve fit on the window of log data at the periodic increments as the window is moved across the log data. The method then determines inflection points of the log data after the curve fit for each of the windows. The method then selects bed boundaries from the inflection points of the curve-fit of the log data.

IPC: H01M50/559
Filed: 1999-01-20
Abstract: In a thin type sealed cell utilizing a cell case made of a laminated material, a storage life and reliability of the cell is increased by preventing a sectional surface at an end of the laminated material from being exposed in the cell case, and thereby a leakage of an electrolyte out of the cell and a short circuit in the cell are avoided. This is achieved by disposing a resin layer on the inner surface of the cell case composed of a sheet type laminated material, and covering the sectional surface existing inside the cell case with resin.

IPC: H04L12/56
Filed: 1998-04-28
Abstract: Signal routing from origination nodes (210) to destination nodes (250) in a spread spectrum communication system (100) is provided using spread spectrum routing codes. Origination nodes (210) and destination nodes (250) are identified using specific codes. Signal routes from origination nodes (210) to destination, nodes (250) are determined in terms of multi-level paths. Different codes are used to identify the different path levels. Data that is to be, sent to a particular user located at a destination node is first spread using the destination code for that destination node. This spread spectrum signal is spread a second time using a first level path code. In addition, the data can be spread a third time using a second-level path code. During the transmission of the spread data decoding processes are performed and the decoded data is routed based on the results of these decoding processes.

Abstract: A mop is provided which has an elongate handle (3), a mop head (5), for carrying a squeezable sponge-like pad mop material (13).      The mop has arm means (27, 29, 37, 39) which can be moved to effect squeezing of the mop material (13). The mop has a two axis swivel connector (7) which has two mutually perpendicular axis (57 and 59). The arrangement is such that the mop head (5) can be swung to various angular orientations relative to the handle (3) and at the same time, the mop permits a two axis swivel connection and means to effect squeezing of the mop material (13). The mop also has the head provided with strengthening webs which resist torsional movement of the mop head as a consequence of squeezing of the mop material.      The swivel connector (7) has a plate like part (73) with an axle (77) which defines axis (57). It also has a central opening (75) which defines an axis (59). Axis (59) is, in turn, provided by an axle (101) on another part (99). Part (99) can mate with another part (85). Parts (85 and 99) form a tubular body with an internal screw thread. A collar (89) can be fitted over the external surfaces of the tubular body containing the screw thread (87). When the handle (3) is screw threaded into the screw thread of the body it radially expands the body tending to force it into tight engagement with the collar (89) and this, in turn, holds the assembly together.
