20080298163 | Vibration Assisted Mixer - An embodiment of a mixer for mixing a powder with a liquid comprises a mix housing to accommodate a mixture of the powder and the liquid, a liquid delivery housing coupled to the mix housing to provide the liquid thereto, and a powder delivery housing coupled to the mix housing to provide the powder thereto, wherein the mixer is configured to induce a vibration therein for substantially avoid an occluding cake build-up of the mixture thereat. | 12-04-2008 |
20090095436 | Composite Casting Method of Wear-Resistant Abrasive Fluid Handling Components - A method of manufacturing composite parts for an apparatus handling abrasive fluids and an apparatus for handling abrasive slurries, for example, a centrifugal pump. Portions of the composite parts are cast in a two-stage process. Portions to be machined are cast in a material suitable for machining and portions exposed to abrasive slurries are cast in a material that is wear-resistant. | 04-16-2009 |
20090193888 | Non-Contact Radar Based Level Measurement Device - A system and method for using a probe-based guided-wave radar sensor to measure fluid level in a container in a non-contact mode are provided. The system and method of the current invention replaces a wall section of the fluid container, such as a steel slurry tub with a panel of radar-transparent material, such as plastic. The level probe is mounted external to the container, adjacent to the radar-transparent panel. By avoiding contact between the sensor probe and the fluid, whether the fluid be cement slurry or another fluid prone to probe degradation, it is possible to eliminate the possibility of contamination, build-up, caking and/or damage to the probe along with the associated degradation in sensor performance. | 08-06-2009 |
20090257303 | Container System - A method and system for providing a homogenized slurry output comprises a container body defining an interior portion, a discharge for supplying the slurry from the container body to a downstream source and at least one inlet in fluid communication with a pressurized supply of slurry for introducing the slurry into the interior portion of the container body in a circulation pattern that creates a homogenized mixture of slurry in the interior portion of the body. | 10-15-2009 |
20100083649 | Configurable Hydraulic System - A configurable hydraulic system facilitates a variety of oilfield cementing and other oilfield or related applications. The system employs a plurality of prime movers to drive a plurality of loads. The plurality of prime movers and loads are coupled with a configurable hydraulic system that maintains a separate, sealed hydraulic system associated with each prime mover. The configurable hydraulic system also enables the load configuration driven by each prime mover to be changed without losing the benefit of a separate, sealed hydraulic system associated with each specific prime mover. | 04-08-2010 |
20100157720 | Vibration Enhanced Mixing Process - A method for mixing a slurry for delivery to a downstream point comprises mixing a liquid source and a powder source at a mixing location to form the slurry, directing the slurry to at least one of a downstream point and a recirculation circuit, and introducing at least one vibration source to promote slurry homogenization and thorough mixing of the slurry for delivery to the downstream point, the vibration source located remote from the mixing location. | 06-24-2010 |
20110155373 | SYSTEM AND METHOD FOR REDUCING FOAM IN MIXING OPERATIONS - A technique facilitates mixing operations by removing foaming that results from air entrained during mixing of constituents. A mixing system comprises a container body having an interior and an inlet through which material enters the interior for mixing. The container body also comprises a discharge through which the mixed material is delivered downstream. A mechanical foam breaker is disposed within the container body and extends upwardly a sufficient distance to extend through a surface level to which the material rises during mixing within the container body. The mechanical foam breaker is oriented to break down foam along the surface of the material as the material moves through the interior. | 06-30-2011 |
20110278013 | TELESCOPING ORIENTATION JOINT - An orientation joint for a subsea landing string equipped to maintain both unitary and telescoping configurations. For example, the joint may maintain a unitary configuration to provide continuous orientation definition while lowering a landing string within a blowout preventer (BOP). Additionally, the orientation joint may be configured to telescope and provide an appropriately sized uniform outer diameter surface to enable a sealing engagement with an aligned ram of the BOP. | 11-17-2011 |
20120325491 | SUBSEA SAFETY VALVE SYSTEM - A valve system for ensuring well closure upon exposure to a predetermined condition even where a well access line is disposed through the valve. This system may be configured with a supplemental power supply capable of effectuating a cutting closure of the valve. Thus, any obstructing well access line such as coiled tubing may be cut during closure to ensure sealing off of the well, even if the cutting mechanism is separated from its traditional power supply by shear or parting of a portion of the landing string. Once more, the supplemental power sufficient for a cutting closure is only provided in the event of a predetermined condition such as the emergence of a potentially hazardous tubular separation. | 12-27-2012 |
