Title: Method and apparatus for sealing pipe perforations
Inventor: KENDRICK LARRY N
IPC: E21B33/138
Filed: 1991-01-07
Abstract: Ball sealers for flowing into casing perforation holes in a wellbore to selectively seal off those perforations. The ball sealers (22) are comprised of a spherical outer deformable shell (42) defining a central core portion filled with nondeformable particulate matter (46) which is sized small enough to flow with the shape of the deformable outer shell (42) and large enough so that as it consolidates under the force of fluid flow pressure, it will cause the outer shell to bridge over the perforation opening (18) when the force of fluid flowing into the casing (12) pushes the ball sealer (22) against and into the perforation opening (18). The particles (46) are also arranged so that when fluid flow is stopped, the particulate matter (46) will become unconsolidated to relax the bridge and permit the entrapped energy in the deformed outer shell (42) to expel the ball from the perforation opening.

Filed: 1992-01-23
Abstract: Methods and apparatus for maintaining a restraining means placed over a load in constant tension as the load shifts during transit are disclosed.  The present invention provides a winch having two ratchets,  the first of which provides the initial tension in the restraining means.  The second ratchet is connected to a spring, which is connected to the shaft upon which the restraining means is wound.  By operating the second ratchet, the spring is displaced and an urging force is created.   Upon a reduction of the initial tension in the restraining means, the urging force acts upon the shaft, advancing the shaft and the first ratchet, thereby maintaining the tension in the restraining means. Since the first ratchet is advanced, any slack in the restraining means is  accumulated and the  strap  is  locked  into  a  tighter position.  Methods and apparatus providing a locking bar to prevent unauthorized use of the winch and theft of the restraining means are also disclosed.

Title: Apparatus and method for facilitating use of a neural network
Inventor: AUSTVOLD SHAWN M
IPC: G06F15/18
Filed: 1992-02-03
Abstract: APPARATUS AND METHOD FOR FACILITATING      USE OF A NEURAL NETWORK                    ABSTRACT      A  neural  network  development  utility  assists  a developer in generating one or more filters for data to be input to or output from a neural network.  A filter is a device which  translates  data  in  accordance with  a  data transformation definition contained in a translate template. Source data for the neural network may be expressed in any arbitrary combination of symbolic or numeric fields in a data base.  The developer selects those fields to be used from an interactive menu.  The utility scans the selected field  entries  in  the  source  data base  to  identify  the logical type of each field, and creates a default translate template based on this scan. Numeric data is automatically scaled.  The developer may use the default template, or edit it from an interactive editor.  When editing the template, the developer may select from a menu of commonly used neural network data formats,  and from a menu of commonly used primitive  mathematical  operations.   The  developer  may interactively  define  additional  filters  to  perform  data transformations  in  series,  thus  achieving  more  complex mathematical  operations  on  the  data.   Templates  may  be edited at any time during the development process.   If a network does not appear to be giving satisfactory results, the  developer may easily  alter  the  template  to present inputs in some other format.
