Abstract: A sensor system is installed adjacent to the buried or submerged metallic pipelines using a plurality of sensors and transceivers. The sensor system monitors the pipeline for external corrosion control and recommends maintenance and repair at specific locations in the pipeline where external corrosion has occurred. The sensor system automatically receives periodic or continuous measurements through the plurality of sensors. The various sensors at various locations adjacent to the pipelines detect irregularities in the received sensor data at specific locations of the pipeline. The sensor data are stored in the system database and can analyzed to be used for monitoring and for transmitting repair alerts. The sensor system according to the present disclosure provides a reliable and an accurate assessment of the external corrosions of the pipelines. The sensor system further obviates the need of personnel walking along the pipelines to detect corrosion.

Abstract: A flight control surface position sensor assembly for an aircraft including a position indicator positioned on a pulley wherein the pulley is secured to the aircraft and the pulley engages a cable associated with a flight control surface of the aircraft. The flight control surface position sensor assembly further includes a sensor which senses rotation of the position indicator with rotation of the pulley.

Abstract: A reciprocating shaft assembly in a reciprocating saw moves in a reciprocal motion and drives a saw blade via a blade holder. At least one bore is formed in an end of the reciprocating shaft assembly opposite the blade holder. A pin fixed to the saw passes through the bore and acts as a bearing to support the reciprocating shaft assembly in its reciprocating motion.

Abstract: A counterweight in a reciprocating saw counterbalances a reciprocating shaft assembly adapted to hold a saw blade. The counterweight is supported for reciprocating motion by slides which ride within slots formed in a housing adapted to hold the reciprocating mechanism.

Abstract: A reciprocating power tool includes a motor operatively connected with a drive assembly for driving a reciprocating shaft, on which a working tool is supported. The reciprocating power tool includes a base so that the tool may stand upright when resting upon the base without the use of external supports. A counterweight positioned inside of the drive housing minimizes vibration. The motor is preferably positioned so that its rotational axis is angled with respect to a longitudinal axis of the reciprocating shaft. This configuration of the motor produces a compact configuration for a reciprocating power tool and helps the tool stand upright upon the base of the tool. A battery may be provided in a cordless embodiment and is advantageously positioned for balancing the tool.
