Peer-to-Peer Redundant File Server System and Methods
InactiveUS20090271412A1Digital data information retrievalMultiple digital computer combinationsHash functionFile system
Peer-to-peer redundant file server system and methods include clients that determine a target storage provider to contact for a particular storage transaction based on a pathname provided by the filesystem and a predetermined scheme such as a hash function applied to a portion of the pathname. Servers use the same scheme to determine where to store relevant file information so that the clients can locate the file information. The target storage provider may store the file itself and / or may store metadata that identifies one or more other storage providers where the file is stored. A file may be replicated in multiple storage providers, and the metadata may include a list of storage providers from which the clients can select (e.g., randomly) in order to access the file.

Method and apparatus for separating particles by size
InactiveUS7108137B2Easy to manufactureLow costWater/sewage treatment with mechanical oscillationsParticle size analysisUltrasonic radiationHigh pressure
A method and apparatus for separating a mixture of particles of various sizes in a capillary tube into groups by size using multiple forces of controlled amplitude. Ultrasonic radiation at a first selected frequency is applied to set up a standing pressure wave in the capillary tube, resulting in a first aggregating force which causes particles of all sizes to aggregate at positions within the capillary tube which correspond to nodes or anti-nodes of the standing wave. Transverse vibrations are also applied to the capillary tube. The frequency of the ultrasonic radiation is adjusted to reduce the magnitude of the first aggregating force. Inertial forces resulting from the transverse vibrations then cause the particles to separate by size. The apparatus and method allows a mixture of particles to be separated by size quickly, without requiring the use of high voltages.

Trailer mounted mobile apparatus for dewatering and recovering formation sand
InactiveUS7240681B2Prevent leakageElectrostatic cleaningMultistage water/sewage treatmentDrive wheelHigh pressure water
An apparatus for removing formation sand from an oil storage tank. The apparatus is mounted to a truck towable trailer so that it may be transported to remote sites. Mounted to the truck towable trailer is a container adapted to accept and dewater a sand-water slurry pumped from the oil storage tank. The slurry is formed by injecting high pressure water from a water reservoir mounted to the truck towable trailer into the approximate centre of mass of the formation sand by way of a pipe having a nozzle generating a spherical spray pattern within the slurry. The pipe is forced into the slurry by way of a two counter-rotating drive wheels in frictional contact with the pipe. Included in the apparatus is a bifurcated conduit adapted for attachment to the storage tank drain port adapted for the injection of high pressure through one branch of the conduit and withdrawal of slurry from the other branch and into the container by way of a slurry pump. The dewatering of the slurry takes place by a plurality of screen filters mounted to the bottom, side and front inside walls of the container. Oil and water extracted from the slurry is recycled back into the storage tank for later removal and treatment. All pumps and conduits are mounted to the truck towable trailer so that the apparatus is self-contained.

Particle separation and concentration system
This invention is based on size and mass separation of suspended particles, including biological matter, which are made to flow in a spiral channel. On the spiral sections, the inward directed transverse pressure field from fluid shear competes with the outward directed centrifugal force to allow for separation of particles. At high velocity, centrifugal force dominates and particles move outward. At low velocities, transverse pressure dominates and the particles move inward. The magnitudes of the two opposing forces depend on flow velocity, particle size, radius of curvature of the spiral section, channel dimensions, and viscosity of the fluid. At the end of the spiral channel, a parallel array of outlets collects separated particles. For any particle size, the required channel dimension is determined by estimating the transit time to reach the side-wall. This time is a function of flow velocity, channel width, viscosity, and radius of curvature. Larger particles may reach the channel wall earlier than the smaller particles which need more time to reach the side wall. Thus a spiral channel may be envisioned by placing multiple outlets along the channel. This technique is inherently scalable over a large size range from sub-millimeter down to 1 μm.
