  • Patent number: 10156233
    Abstract: A continuous run controller for a dual control compressor system includes an integrated housing containing a pilot valve and a hydraulic unloader valve. Low pressure in the hydraulic oil system opens the hydraulic unloader valve such that the suction valve unloader assembly unloads the compressor. High pressure in an air receiver of the compressor system opens the pilot valve such that the suction valve unloader assembly unloads the compressor.

  • Publication number: 20180246485
    Abstract: A programming module, systems, and methods for programming a motor controller coupled to a motor are provided. The programming module includes a connector for coupling to a system control wire harness of a system control board and a wire harness for coupling to a motor connector of the motor controller such that the programming module is serially coupled between the system control board and the motor controller. The module also includes a tap detection circuit coupled to the connector for detecting which tap of a plurality of motor taps is called by the system control board. A wireless communication device is configured to transmit an identification of the called tap wirelessly to a programming computing device, receive an adjusted operating parameter for the motor that is associated with the called tap from the programming computing device, and transmit, via the wire harness, the adjusted operating parameter to the motor controller.

  • Patent number: 8353238
    Abstract: A blind-mating rocket launcher connector and protection system having a connector, a floating connector member, a cam, a connector cover, and a linkage between the cam and connector cover whereby the connector may mate with a second connector when the cam is displaced despite misalignments between the first and second connector. For the preferred embodiment, the floating connector member has multiple degrees of freedom with a reduced diameter portion and a lengthwise key whereby the connector is capable of mating with an aerodynamic hood of a rocket. The preferred embodiment biases and closes the connector cover upon the connector prior to a plume of the rocket passes the connector whereby exposure of the connector to the deleterious effects of the plume are minimized.

  • Publication number: 20070112102
    Abstract: The present invention is directed to a process for preparing a polymer modified bituminous binder composition in the substantial absence of crosslinking agents by heating a bitumen component in a stirred tank to a temperature from 185° C. to 221° C.; adding a block copolymer composition to the bitumen component while the bitumen component is being stirred to form a homogeneous mixture of the bitumen component and the block copolymer composition; and continuing to stir the homogeneous mixture while maintaining the temperature from 185° C. to 221° C. for a period of time from 4 hours to 30 hours thereby forming a cured polymer modified bituminous binder composition.
