Abstract: The support tool described includes a body with a lower narrow portion dimensioned to fit within the interior cavity of a tubing string inlet or an upper wellhead extension thereof. The body has an upper wide diameter portion defining a landing surface substantially perpendicular to a longitudinal axis of the support tool. The landing surface is dimensioned to rest upon the top edge of the tubing string inlet or the upper wellhead extension thereof. The body includes a central interior longitudinal cavity spanning the length of the tool which is continuous with a longitudinal slot in the outer sidewall of the tool spanning the length of the tool. A sucker rod is held within the longitudinal cavity when the tool is supported on the top edge of the tubing string inlet or an upper wellhead extension thereof.

Abstract: A method of patterning a device includes forming a fluorinated photopolymer layer over a device substrate. The photopolymer layer has a lower portion proximate the device substrate and an upper portion distal the device substrate. The fluorinated photopolymer layer includes a radiation-absorbing dye and a fluorinated photopolymer having a solubility-altering reactive group. The photopolymer layer is exposed to patterned radiation to form exposed and unexposed areas in accordance with the patterned radiation and a developed structure is formed by removing unexposed areas using a developing agent that includes a first fluorinated solvent. The lower portion of the exposed area of the photopolymer layer has a dissolution rate in the developing agent that is at least 5 times higher than a dissolution rate for the upper portion.

Abstract: A method and system for visually guiding an aircraft in its landing approach to a runway having an approach area equipped with approach lights operable in off, low, medium, and high intensity states. The lights are communicated with a secondary side of a transformer, which has a primary side with low, medium, and high taps that correspond to the light states. Off, low, medium, and high lighting intensity requests correspond to the low, medium, and high states of the plurality of lights. AC power is switched between the transformer taps in response to a request for an increase in lighting intensity. Power is sequentially applied to the taps by supplying the power to the low tap for a first predetermined time interval before supplying the power to the medium tap.

Abstract: A communication apparatus (100) provides an interface between a cellular encryption and decryption apparatus (150) and a telephone line (91) allowing for communication of secure data of the telephone line using a regular telephone (70). The communication apparatus (100) provides for the receipt of incoming secure data in an unattended data mode, and also allows the telephone to be used in either a secure mode or clear mode. The communication apparatus monitors the telephone line (91) for secure tones while operating in the clear mode. When a secure tone is detected, the communication apparatus (100) breaks the path between the PSTN (90) and the telephone (70) and routes the signals to the cellular encryption and decryption apparatus (150) to establish a secure call.
