  • Patent number: 10625933
    Abstract: A system and methodology facilitates the handling of oilfield material. The oilfield material is stored in at least one silo which enables use of gravity to feed the oilfield material to a blender or other suitable equipment. Each modular silo is transportable and may be engaged with a support structure via a pivot connection. Once engaged, the silo is pivoted to a raised, upright position on the support structure. The oilfield material is then moved to an interior of the silo, and gravity may be used to feed the oilfield material to a blender or other equipment in a controlled manner.

  • Patent number: 10618725
    Abstract: A technique facilitates delivery of bulk materials at a desired site, such as a wellsite. According to an embodiment, a silo is pivotably mounted to a trailer, such as an over-the-road trailer. An actuator is coupled between the silo and the trailer to enable transition of the silo between a transverse position for transport and an upright position which facilitates outflow of the bulk material. The system also may comprise various other features used alone or in combination, such as pivotable wings, a foldable trailer, and an adjustable suspension which allows a frame of the trailer to be positioned firmly on the ground.

  • Patent number: 10589923
    Abstract: A mobile support structure (MSS) includes a frame structure for receiving modular silos, a base moveable between transportation and support configurations, and connectors coupling with the silos. A mobile erecting assembly includes a chassis, a lift structure rotatable between transportation and mounting orientations while engaged with a silo, an engagement structure movable between first and second positions while engaged with the silo, and an actuator to move the engagement structure and silo between the first and second positions. The silo is connected to the mobile erector assembly in the transportation orientation, and the mobile erector assembly is then aligned relative to the MSS, such as by engaging an alignment member of the mobile erector assembly with a chassis alignment post of the MSS. The mobile erector assembly is then operated to move the silo to the mounting orientation, and the silo is then coupled to the MSS.

  • Publication number: 20200035633
    Abstract: A microelectronic device has a pillar connected to an external terminal by an intermetallic joint. Either the pillar or the external terminal, or both, include copper in direct contact with the intermetallic joint. The intermetallic joint includes at least 90 weight percent of at least one copper-tin intermetallic compound. The intermetallic joint is free of voids having a combined volume greater than 10 percent of a volume of the intermetallic joint; and free of a void having a volume greater than 5 percent of the volume of the intermetallic joint. The microelectronic device may be formed using solder which includes at least 93 weight percent tin, 0.5 weight percent to 5.0 weight percent silver, and 0.4 weight percent to 1.0 weight percent copper, to form a solder joint between the pillar and the external terminal, followed by thermal aging to convert the solder joint to the intermetallic joint.

  • Patent number: 10527140
    Abstract: An articulation mechanism for large scale mobile aggregate system equipment. The mechanism includes a screw device that is pivotally secured to an elongated portion of the equipment to drive its movement to and from a collapsed position. The screw device is driven by a screw jack and moved within a housing while the housing itself is pivotally secured to another portion of the equipment. Rollers within the housing may be used to stabilize the lateral movement of the screw device during the opening, closing or self-locking of the elongated portion by the mechanism.

  • Publication number: 20180119826
    Abstract: A thermal management module is provided that includes a housing, a rotary valve, and a sealing assembly arranged in a passageway of the housing. The sealing assembly includes a main seal, a secondary seal, and a seal support. The main seal is loose-fitting on the seal support and is loose-fitting in the housing, allowing rotation of the main seal. The rotating seal will wear uniformly, thereby reducing wear, and maintain good sealing performance throughout the lifetime of the thermal management module. The rotary valve can be configured with an opening that is asymmetric in relation to an axial direction of the rotary valve, thereby providing a rotational torque for turning the main seal. The opening of the rotary valve can have a die parting line that is inclined relative to the axial direction of the rotary valve, also providing a rotational torque for turning the main seal.
