Abstract: The present invention relates to two improved methods for multilateral completion and cementing (e. g. sealing) the juncture between primary and lateral wellbores. These two completion methods of the present invention address the issue of cementation of the lateral wellbores for the purpose of zonal isolation. It is desirable to have the ability to re-enter each lateral wellbore as well as maintain the option to perform any function that could be done in a single wellbore.      For this reason, cemented lateral wellbores are desirable so that normal isolation, stimulation or any other operation can be achieved.      The methods allow sealing and reworking of either wellbores with single laterals or multiple laterals and provide safe durable junctions therebetween.

Filed: 1995-09-18
Granted: 2001-07-31
Abstract: Apparatus for visualizing slices of transitive closures of entities having dependence relationships with one another. A preferred embodiment visualizes slices of programs. A display in a computer system includes reduced representations of thefiles, procedures, and lines making up a program. The user employs a pointing device to interactively select a reduced representation as the slice point and the apparatus computes the slice and changes the color of the reduced representations in the slice. The color of the reduced representation indicates the distance of the entity represented by the reduced representation from the slice point. The display may be rearranged so that files and procedures are ordered by distance from the slice point. Other aspects of the display include scaling the size of the reduced representation of a procedure to indicate the number of lines in the procedure and filling the reduced representation of the procedure according to the number of lines belonging to the slice which are contained in the procedure. A user may select open and closed representations of procedures. The open representation of a procedure contains reduced representations of the lines in the procedure. The apparatus also includes a viewer for viewing the text of lines in the program.

Title: Pit membrane-broken wood drying method and apparatus
Inventor: ANDO MINORU
IPC: B27K5/00
Filed: 1995-10-12
Granted: 2004-12-21
Abstract: The present invention is intended to artificially break pit membranes in cell membranes of cells constituting wood and then to readily attain dryness of the wood. In view of the fact that one pit or the other pit of pits in the form of a pair is blocked with the torus 1 in felled wood to cause poor removal of water in cells, it is intended to prevent the blockage of the pit membrane, i.e., to break the pit membrane per se, thereby facilitating easy escapement of water in cells after the breaking. In the present invention, wood fuel is burned, and subject wood is allowed to stand in a treatment chamber filled with smoky wood gas generated by the combustion for a predetermined period of time, to expose the subject wood to far-infrared radiation and components contained in the wood gas. Further, ceramic material for multiplying far-infrared radiation or high-density lava is heaped in a combustion chamber with appropriate gaps left therebetween, thereby effecting heat reservation and further multiplication of far-infrared radiation. Accordingly, the subject wood is irradiated with a large amount of far-infrared radiation, thereby preventing the torus of the wood from blocking up one pit or the other pit of pits in the form of a pair to form gaps in the pits.

IPC: B26B19/38
Filed: 1996-06-25
Granted: 1999-04-27
Abstract: A unique, highly effective, electric dry shaver incorporating rotary cutting blades for use by women to effectively, conveniently, and comfortably shave bothlegs and underarms is achieved by incorporating a blade guard removably mountable to the electric shaver for partially blocking the rotary cutting blades while also smoothing and/or stretching the soft underarm skin.  By employing the rotary cutting blade guard of the present invention, the soft, pliable skin typically found in underarms is comfortably smoothed, spread, and/or stretched to prevent any cutting or pinching of the skin by the blades.  As a result, a close, comfortable shave is attained, with all of the hair being completed cut, regardless of the contours of the skin surface or the soft, pliable nature of the skin.  Furthermore, when the legs are to be shaven, the blade guard  is removed thereby  fully exposing the side walls of the slotted outer cutter so it can be used in its entirety.

Title: System and method for conducting cashless transactions
Inventor: HOGAN EDWARD J
IPC: G06F17/00
Filed: 1994-12-01
Granted: 2000-10-03
Abstract: In a commercial transaction system a system user uses a card device to interact with sales or transaction terminals to conduct cashless transactions. Each terminal processes data including a balance stored on the card device and updates the stored data at the end of the transaction. The system is specially designed for purchases of items or transactions of relatively small monetary value, where purchases are generally unattended by salespersons. In this manner, the amount of the transaction is deducted from the balance on the card device. In accordance with the invention, when the existing balance associated with the card does not cover the price of the transaction, the system provides an automatic renewal feature which automatically increases the balance of the card device by a predetermined amount. Such a feature allows the purchase to be made without . the card user to increase the balance by other means. Each time the balance is increased by an automatic renewal, the card issuing bank bills the card user for increments of the predetermined amount.
