  • Patent number: 10920553
    Abstract: A blender apparatus is disclosed having a chassis, a mixer positioned on the chassis, and a transfer pump positioned on the chassis. The mixer has a mixer housing defining a first mixer inlet, a second mixer inlet, and a mixer outlet. The first mixer inlet receives a liquid component, and the second mixer inlet receives a dry component. The mixer pressurizes at least the liquid component within the housing and discharges the liquid component through the mixer outlet at a first pressure above hydrostatic pressure. The transfer pump has a pump housing defining a pump inlet, a pump outlet and is devoid of an inlet configured to receive a dry component through a gravity feed. The transfer pump receives the liquid component through the pump inlet, pressurizes the liquid component within the pump housing, and discharges the liquid component through the pump outlet at a second pressure above hydrostatic pressure.

  • Patent number: 8662249
    Abstract: A sound attenuation mechanism made up of multiple substrate layers, including corrugated layers. The use of corrugation provides an inexpensive and manner of forming a plurality of highly effective acoustic attenuation channels throughout the mechanism. The multi-layered mechanism may be provided in a variety of modular forms and sizes which may be combined to form a low-cost, highly effective attenuation housing. For example, such a housing may be utilized to contain otherwise noisy large scale oilfield equipment such as coiled tubing engines. Additionally, where drainage from the housing is sought, a spiraled attenuation channel may be employed such that the effectiveness of the attenuation provided by the housing is not sacrificed.
