Abstract: A plow assembly includes a housing, a shaft having a first eccentricity and a shaft having a second eccentricity. The shaft having a first eccentricity is mounted within the housing for rotation about a first axis of rotation, and the shaft having a second eccentricity is mounted within the housing for rotation about a second axis of rotation. The assembly also includes a surface breaker blade and a balancing assembly. The surface breaker blade is mounted on the shaft having a first eccentricity in such a manner that rotation of the shaft having a first eccentricity causes the surface breaker blade to move in response to the first eccentricity of the shaft. The balancing assembly is mounted on the shaft having the second eccentricity in such a manner that rotation of the shaft having the second eccentricity causes the balancing assembly to move in response to the second eccentricity of the shaft.

Abstract: A handling assembly for pipe sections for a horizontal directional drill includes a thrust frame and a pipe handler assembly track that is attached to the thrust frame so as to define a pipe section transfer location. The handling assembly also includes a pipe handler carrier that is mounted on the pipe handler assembly track and a magazine that is mounted adjacent to the pipe handler carrier and adapted to discharge a pipe section from the bottom of a selected column to the pipe section transfer location. The pipe handler carrier may be moved along the pipe handler assembly track to a plurality of positions in each of which a pipe section at the bottom of a column of the magazine is aligned with the transfer location, and a column selector rod is mounted with respect to the thrust frame so as to selectively locate the pipe handler carrier along the pipe handler assembly track at a position to align a column of the magazine with the pipe section transfer location.

Abstract: A control system for controlling at least one function of an item of construction equipment. The control system includes a pump, a proportional control valve, a directional control valve, a signal source, a switch, and a processor. The proportional control valve is in fluid communication with the pump and the directional control valve is in fluid communication with the proportional control valve. The switch is adapted to be in an open position and in a closed position. The processor is adapted to receive a processor input, receive the signal from the signal source, and transmit a processor output to the proportional control valve. The switch transmits a false signal to the processor when it is in the open position and a true signal when it is in the closed position. The control system is adapted to control the at least one function of the item of construction equipment.

Abstract: A hydraulic fluid tank for a drilling machine includes a primary chamber and a secondary chamber. The primary chamber is located entirely below the hydraulic pump of the drilling machine, and the secondary chamber is located above and in fluid communication with the primary chamber. The secondary chamber is adapted to maintain a hydraulic fluid level that is above the pump suction centerline of the drilling machine pump as the hydraulic fluid in the tank reaches its normal operating temperature during operation of the drilling machine. The secondary chamber is also sized and configured to allow for thermal expansion of hydraulic fluid in the amount of at least about 5% of the total tank volume as the hydraulic fluid in the tank reaches its normal operating temperature during operation of the drilling machine.

Abstract: A method and apparatus for predicting write failure resulting from flying height modulation and initiating re-writing of data upon occurrence of the predicted write failure is disclosed. According to the present invention, if the slider or transducer flying height modulates during the write process, such modulation is detected, and a rewrite of the same data is forced. A write reassign may be initiated when a thermal signal exceeding the predetermined threshold is detected during the rewrite and/or a read/verify may be initiated after the rewrite.

Abstract: A spray assembly for applying a fluid material to a surface includes a first spray bar and a second spray bar, each of which is mounted for movement along an axis. Each spray bar includes a plurality of nozzles, each of which is associated with a valve that can be opened or closed. Each nozzle is adapted to dispense a fluid material in a defined spray pattern onto the surface. The nozzles are spaced along the length of the spray bar to which they are attached and disposed above the surface so that the spray pattern from any nozzle on a spray bar does not overlap the spray pattern of a longitudinally adjacent nozzle. The assembly also includes a source of fluid material, and a fluid circuit through which fluid material may be supplied to each of the nozzles. Components of the assembly are also provided for intercepting at least a portion of the spray from a nozzle of the second spray bar to prevent the spray pattern from such nozzle from overlapping with the spray pattern from a nozzle of the first spray bar.
