    摘要: A method of transferring proppant materials, wherein the method includes providing a first pressurized container (102) containing proppant materials on a first vessel (106). The method also includes connecting the first pressurized container (102) on the first vessel (106) to a second container (102) on a second vessel (114) and transferring pneumatically, proppant materials from the first pressurized container (102) on the first vessel (106) to the second container (102) on the second vessel (114). Also, a method of transferring proppant materials, the method including removing a wellbore fluid comprising excess proppant materials from a well, and screening the excess proppant materials from the wellbore fluid. The method also includes transferring the excess proppant materials to a first pressurized container (102) and transferring pneumatically, the excess proppant materials from the first pressurized container to a second pressurized container.

    摘要: A furniture swivel for rotatably coupling first and second furniture components is disclosed. The furniture swivel includes a base, a rotor, and a retainer. The base may have a lower end for connecting to a first furniture component and an upper end including a planar base bearing surface. The rotor may have an upper end having a first portion for connecting to a second furniture component, and a lower end including a planar rotor bearing surface in sliding contact with the base bearing surface to form a plane bearing absent rolling elements for supporting the rotor and the first furniture component on the base. The retainer may be coupled to the base for substantially inhibiting translation of the rotor relative to the base.

    摘要: An exemplary power inverter comprises a push-pull inverter circuit that includes a transformer having a primary winding coupled to a DC bus and a secondary winding coupled to an AC bus, main power switches coupling each end of the primary winding to a DC return, and one or more supplemental power switches coupling at least one end of the primary winding to a snubber bus. The supplemental switch at a given end of the primary winding forms a buck-mode converter in combination with the primary winding and the associated free-wheeling diode at that end of the primary winding, and can be controlled by a switching controller to effect energy transfer between the snubber bus and DC bus. The switching controller can be configured to control power flow between the DC, AC, and snubber buses by controlling the common-mode and differential-mode voltages of the primary winding via main/supplemental power switch control.
