  • Patent number: 10039199
    Abstract: An adapter has two conductors each with a U-shaped bend forming upper longer legs and lower shorter legs. The conductors face each other with the longer legs linearly aligned with each other and the shorter legs aligned with each other, thereby forming a first gap between the longer legs and a second gap between the shorter legs. The first gap is substantially smaller than the second gap, so that an electrical package can be placed across the first gap to contact the two upper longer legs, while the two shorter legs are spaced further apart to span a larger gap between conductors of a connector. Thus, the adapter enables the electrical package to be connected to conductors having a gap that is larger than the electrical package.

The feed through connector comprises a body with opposing first and second ends, at least one electrical interconnection extending axially through the body and out of both ends, and a pressure transducer receptacle in the first end and a communications bore extending from the receptacle to the second end. The pressure transducer is seated in the receptacle such that a pressure at the first end can be measured, and comprises at least one electrical contact that extends from the pressure transducer through the communication bore and out of the second end. The pressure transducer can take pressure measurements for predicting wear of a primary seal in a motor subassembly of the tool, detect a pressure-related battery failure event, and control operation of a dual pulse height fluid pressure pulse generator.

  • Patent number: 9664187
    Abstract: A pen-type pressure indicator, which can be detachably connected to an air compressor for measuring the pressure of compressed air produced in the air compressor, includes a transparent tube and a slider. The slider can be moved along a first bore and a second bore of the transparent tube. The motion of the slider in the transparent tube is similar to the motion of a piston in a cylinder. The transparent tube is provided with a tapered annular surface, between the first bore and the second bore. In addition to measuring the pressure of the compressed air delivered to an object, when the pressure of the compressed air exceeds a predetermined pressure, excessive air can be released into the environment, without requiring the air compressor to be installed with a safety valve, so that the object can be protected from damages due to overpressure.
