Title: Batting cage with user interactive selection of ball speed and strike zone with pitch height indicator lamps
Inventor: HALL RICHARD E
IPC: A63B69/40
Filed: 1999-04-20
Abstract: The invention is a pitching system with a pitching mechanism. A control panel allows a user to separately control ball speed and tilt angle. The control panel also displays an estimated height at which the ball will cross the plate for the selected ball speed and tilt angle. In the preferred embodiment, a vertical row of lamps shows the estimated ball height.  The control panel can include symbology to indicate strike zones for batters of different heights. To operate the batting cage, the batter selects the desired ball speed. The control panel displays an estimated ball height based on the selected ball speed and current tilt angle. The batter then adjusts the tilt angle of the pitching mechanism until a desired ball height is reached. The batter then starts the machine. In this manner, the batter avoids wasting balls selecting a preferred choice of ball speed and height. The batter can also change ball speed and tilt angle during a pitching sequence, to alter the strike zone through which balls are pitched.

Patent CA-2270759-A1 (CA)
Title: Removable bridge plug or packer
Inventor: MCMAHAN MICHAEL E
IPC: E21B33/12
Filed: 1999-05-04
Abstract: A composite packer or bridge plug is disclosed. The design features substantially all nonmetallic components. The design allows the setting tool metallic components to be retrieved after the bridge plug is set. The slips contain flats with mating flats on the cones which extend to one end of the cones and guides for the slips to facilitate proper slip movement into engagement with the wellbore. A lock ring rides on the nonmetallic mandrel and secures the set, using a buttress-type thread to engage into the mandrel body. Alternative designs are revealed for backup to the sealing elements to prevent extrusion. In one design, split rings are axially compressed so that they grow in radial dimension to act as extrusion barriers. In another design, tapered scored rings are rotationally locked against each other and are axially compressed so that they bend into contact with the wellbore to act as extrusion barriers. Axial travel to obtain an extrusion barrier is minimized.  The slips are made of a cohesive component and separate from each other upon advancement with respect to the cone. Mandrels of different plugs can lock together to facilitate mill-out in multi-plug installations.

Title: Pressure-balanced rod piston control system for a subsurface safety val ve
Inventor: ALLISON JAMES
IPC: E21B34/00
Filed: 1999-10-15
Abstract: A control system for a subsurface safety valve (SSV) comprising of a control line from the surface in fluid communication with the top side of an actuating piston which moves a flow tube downwardly to open the SSV. A balance line runs from the surface to the bottom side of the same actuating piston to put the actuating piston in pressure balance. A buildup of pressure in the control line overcomes a return spring to open the valve, while removal of pressure from the control line allows the return spring to close the valve.      Seals and leakpaths are provided through the actuating piston so that, depending on the hydrostatic pressure in the control line and the size of the return spring, the various failure modes of the actuating piston seals and control line or balance line will preferentially result in a fail-closed situation in the SSV.

Title: Method and apparatus for remote location, identification and/or control of motor vehicles
Inventor: MARTENS LARRY
IPC: B60R25/04
Filed: 1999-11-22
Abstract: This invention is known as PCEL, an acronym derived from the descriptive name Police Chase ELiminator. The invention provides an RF means for isolating, identifying, locating, controlling the speed of, and stopping a particular motor vehicle.  Police vehicles will have an on-board computer which will issue secure RF signals to nearby traffic, causing vehicles receiving that signal to respond with their individual identifier code and physical description. Through a repeated polling process, the police computer will be able to isolate a single "target" vehicle, then either keep it under surveillance, make it slow down, or cause the vehicle's engine to stop on command.  Controlling the speed and stopping of the engine will be accomplished through remote interruption of the vehicle's ignition system.

Title: Filtering material and device and method of its manufacture
Inventor: DUBSON ALEXANDER
IPC: B01D39/16
Filed: 1999-12-02
Abstract: A device and method for producing a porous fiber structure. One or more points of high surface curvature is produced in a liquefied; polymer, such as a polymer solution or a polymer melt. The points of high surface curvature may be produced by forcing the liquefied polymer through narrow nozzles, or by wetting sharp protrusions with the liquefied polymer. The liquefied polymer is charged to a high negative electrical potential relative to a grounded moving belt. Thin jets of liquefied polymer emerge from the points of high surface curvature to impinge as fibers on the moving belt, thereby forming an unwoven fiber structure of relatively uniform porosity. A powdered aerosol is charged to a high positive electrical potential relative to the moving belt. As the belt moves past the aerosol, the aerosol particles are attracted to fill interstices in the fiber structure, thereby creating a composite filtering material.
