  • Patent number: 10935011
    Abstract: A pump system/method configured to provide substantially constant flow of concrete, cement, or other material is disclosed. The system integrates a trapezoidal cutting ring and spectacle plate in conjunction with lofted transitional interfaces to the mechanical pump cylinder rams and output ejection port to ensure that pressurized discharge concrete material is not allowed to be relaxed nor backflow into the material sourcing hopper. The trapezoidal cutting ring is configured to completely seal off the trapezoidal spectacle ports as it smoothly transitions between the mechanical pump input ports during cycle changes thus generating a more uniform output flow of concrete while eliminating hopper backflow and hydraulic fluid shock. A control system is configured to coordinate operation of the hydraulic pump cylinder rams and cutting ring to ensure that output ejection port pressure and material flow is maintained at a relatively constant level throughout all portions of the pumping cycle.

  • Patent number: 10227974
    Abstract: A pressure monitoring apparatus for a membrane compressor, with at least one pressure transducer for recording the pressure within a certain volume, with at least one nonreturn valve and with at least one shutoff valve, for blocking of the nonreturn valve, the shutoff valve and the nonreturn valve each being located in a flow path through which a medium can flow between the volume and the pressure transducer. A pressure monitoring unit delivers exact measured values and which can be economically implemented is achieved by there being at least two nonreturn valves which are located anti-parallel in respective flow paths, the first nonreturn valve blocking in the flow direction from the volume to the pressure transducer and the second nonreturn valve blocking in the flow direction from the pressure transducer to the volume, and by there being at least two shutoff valves for blocking a respective flow path.

  • Patent number: 10061312
    Abstract: Sensor management systems for computer assisted or autonomous driving vehicles are disclosed herein. A computer assisted or autonomous driving vehicle may be provided with a plurality of sensors and a sensor management system configured to predictively maintain effectiveness of the plurality of sensors, based at least in part on predicted cleaning needs of the sensors, predicted obstruction or destruction events of the sensors, or predicted environmental or operating conditions. In embodiments, the sensor management system may be coupled to a navigation system of the vehicle, and may, in response to a predicted sensor obstruction or destruction event, change a navigation parameter of the vehicle to avoid the event. Alternatively, if the predicted event is determined to be within an acceptable risk tolerance threshold, the sensor management system may follow an original navigational route but implement event avoidance actions. Other embodiments may be disclosed or claimed.

  • Patent number: 10047741
    Abstract: A monitoring system for a fluid pump having a fluid end and a power end is provided. The monitoring system includes an inlet pressure sensor attached to an inlet manifold of the fluid end. The inlet pressure sensor generates a signal indicative of an inlet pressure of a fluid being supplied to the fluid end. The monitoring system includes a discharge pressure sensor attached to the fluid end. The discharge pressure sensor generates a signal indicative of a discharge pressure of the fluid exiting the fluid end. The monitoring system includes at least one accelerometer attached to the fluid end. The accelerometer generates a signal indicative of vibrational data of the fluid pump. The monitoring system includes a controller which receives signals from the inlet pressure sensor, the discharge pressure sensor and the accelerometer and determines a possible failure mode of the fluid pump.
