Abstract: Systems and methods for monitoring the performance of reciprocating compressors are disclosed. The monitoring system includes inductive power generation at individual cylinders of the compressor, alleviating the need to run power supply and conduits to each of the cylinders. The inductive system also allows piston position to be determined at each cylinder. Data acquired at each cylinder can be telemetered to a central hub for processing.

Abstract: An electrical enclosure includes an electrical box and a cover mounted onto the electrical box. A 3/8-7 lag bolt extends through the cover and engages a coil nut for securing the cover to the electrical box or underground enclosure. The coil nut includes a body having two ends with an aperture therebetween. The aperture has a continuous internal thread formed between the first and second ends. The size of the continuous internal thread is seven individual threads per inch such that the distance, or pitch, between first and second centers of first and second threads, respectively is 0.143 inches. The pitch and the diameter determine the seven threads per inch size of the continuous thread by accounting for the minor diameter and the major diameter of the nut.

Abstract: An alignment and installation strap for a presloped drainage channel run is disclosed wherein the strap includes a body and two arms perpendicular to said body, a spike attachment means on each arm and at least two thread holes with bolts on each arm, the holes being placed so that when the strap is placed over or under two adjacent drainage channel sections one of the bolts on each arm will screw into an indentation on each outside wall of one channel section and the other bolt on each arm will screw into an indentation on each outside wall of the second channel section when the two sections are correctly aligned and the two spike attachment means will accept, slide over and attach to two spikes which may be driven into the ground.
