Abstract: A replacement method facilitates replacing of a portion of a combustor liner within a gas turbine engine combustor in a cost-effective and reliable manner. The combustor includes a combustion zone that is defined by an inner and an outer liner. The inner and outer liners each include a series of panels and a plurality of nuggets formed by adjacent panels. The method includes the steps of cutting between an outer surface and an inner surface of at least one liner panel, removing at least one panel that is adjacent the area of the liner that was cut, and installing a replacement panel into the combustor for each panel that was removed from the combustor.

Abstract: A method of operating a control pedal assembly includes the steps providing a pair of adjustable control pedals. Each control pedal includes a first support and a second support having a lower arm and moveable relative to the first support to adjust the fore-aft position of the lower arm upon operation of a motor. A predetermined fore-aft relationship is provided between the lower arms of each of the pair of control pedals. The predetermined fore-aft relationship is maintained during operation of the motor to move the second supports relative to the first supports while adjusting the fore-aft position of the lower arms. The motor is stopped during operation if the predetermined fore-aft relationship between the lower arms is not maintained.

Abstract: Methods for validating fields of a form are provided. In a client-server transaction, wherein a form is received by the server having one or more fields associated therewith. Input data are received from the client and associated with the fields of the form, once the input data are received on the server, or within the fields of the form, it is validated.

Abstract: A portable computer laptop desk is provided when attached to a structure that in turn is supported on web strapping that passes over the upper legs of the operator when in the seated position. The strapping is attached to foldable and telescopable side and center supports for the structure that slide into and fold over the structure forming a package comparable in size to the portable computer.

Abstract: An apparatus for ultrasonically examining a weld in a nuclear steam supply system includes an elongated guide rod for positioning within a pipe of the nuclear steam supply system. An ultrasonic transducer is positioned at an end of the elongated guide rod. A collapsible shoe encloses the ultrasonic transducer. The collapsible shoe includes a biasing mechanism to allow the collapsible shoe to pass through the pipe while the pipe is at a first circumference and while the pipe is at a second circumference. The collapsible shoe continuously contacts the pipe to establish ultrasonic coupling for the ultrasonic transducer.

Abstract: An adjustable control pedal for a motor vehicle includes a first member having a slot formed therein, a pin laterally extending into the slot and having an abutment facing the first member on a side of the first member opposite the second member, and a second member rigidly secured to the pin and movable relative to the first member along the slot. A plastic bushing encircles the pin and extends into the slot. The bushing has a flange engaging the first member on a side of the first member opposite the second member. A plastic washer encircles the pin and is located between the first and second members. A spring washer such as a wave or Belleville washer is located between the abutment and the flange and resiliently biases the second member relative to the first member to resist relative lateral movement between the first and second members to reduce lash therebetween. The pin can be ether a guide pin or a drive pin of the control pedal.

Abstract: An adjustable control pedal for a motor vehicle includes an upper arm and a lower arm carrying a pedal. The lower arm is selectively moveable relative to the upper arm to adjust the position of the pedal relative to the upper arm. A drive screw is secured to the upper arm. A drive nut threadably engages the drive screw and is adapted to move axially along the drive screw upon rotation of the drive screw. A motor is operatively connected to the drive screw to selectively rotate the drive screw. The lower arm is operatively connected to the drive nut for fore-aft movement of the lower arm relative to the upper arm upon axial movement of the drive nut along the drive screw. A control system includes a sensor located at the drive screw and adapted to directly sense rotation of the drive screw and a controller in communication with the sensor to receive electrical signals from the sensor.

Abstract: A system, method and program to help a user retrieve previously accessed documents are retroactively determined to be of interest. The bookmarking process associated with a receiving display station for the selection of received documents to thereby store at said receiving display station, direct links to such documents for future access are modified so that they include the following: a combination of an implementation at the receiving display station for tracking the number of times each document is received and a function responsive to these tracking means for bookmarking a received document after said document has been received a predetermined number of times at the receiving display station. A process may be optionally included for permitting a user at said receiving display station to change said predetermined number of times.

Abstract: A method of repairing an annular transpiration cooled liner for a combustion chamber of a gas turbine engine. An annular portion of the liner including a damaged region is removed from between an upstream section and a downstream section of the liner. Sheet metal is formed into an annular replacement section having at least one axial seam extending between an upstream end and a downstream end of the replacement section. The replacement section is sized and shaped similarly to the removed annular portion of the liner. The upstream end of the formed annular section is joined to the upstream section of the liner and the downstream end of the formed annular section is joined to the downstream section of the liner.
