Abstract: A method of producing a well treatment fluid. A crude oil is obtained that has been produced directly from a hydrocarbon bearing formation, the crude oil having hydrocarbons with between one and six carbon atoms and hydrocarbons having more than 20 carbon atoms. The crude oil is refined to remove substantially all hydrocarbons from the fluid where the hydrocarbons have fewer than six carbon atoms and to remove substantially all hydrocarbons where the hydrocarbons have more than 20 carbon atoms. A method of treating a well. Determe the type of contaminants clogging a well. Refine produced fluid from the well to remove heavier ends to produce a treatment fluid. Inject the treatment fluid into the well. A method of treating a well. Sample well fluid in the well at a downhole sample point to produce a downhole sample of the well fluid. Sample produced well fluid from the well at the surface to produce a surface sample of the well fluid.  Analyze the downhole sample and the surface sample to determine well fluid contaminants lost from the well fluid in transit between the downhole sample point and the surface. Treat the well with a well treatment fluid based upon characteristics of the lost contaminants.  Preferably, carry out these process at a well site.

Granted: 2003-08-12
Abstract: A carbon fiber carbon matrix hybrid adsorbent monolith with enhanced thermal  conductivity for storing and releasing gas through adsorption and desorption  is disclosed. The heat of adsorption of the gas species being adsorbed is sufficiently large to cause hybrid monolith heating during adsorption and hybrid monolith cooling during desorption which significantly reduces the storage capacity of the hybrid monolith, or efficiency and economics of a ga s separation process. The extent of this phenomenon depends, to a large extent , on the thermal conductivity of the adsorbent hybrid monolith. This invention  is a hybrid version of a carbon fiber monolith, which offers significant enhancements to thermal conductivity and potential for improved gas separati on and storage systems.

Abstract: A cage like compactor and dryer apparatus comprising a cylindrical body (10) formed by conduits (11) arranged according to its generatrix lines and run through by a heat transfer fluid intended to heat the waste material contained therein (textile or foodstuff wastes, municipal solid wastes). The individual conduits (11) are spaced apart so as to form vapour outflow paths for the water vapour, having longitudinal dimension corresponding to the whole heating length of the cylindrical body (10). Pressure plates (14) form the mobile bases of the cylindrical body (10) in order to generate the needed axial pressure.  Suitable hoops (12) arranged in spaced apart relation constrain said conduits (11) in order to withstand the radial components of the longitudinal forces. The ground connections of the cylindrical body (10), when it is horizontally mounted, are realised by running trolleys (15) aimed at minimising the stresses generated by the temperature variations.

Abstract: A clamp assembly for releasably securing a cab or other truck toppers to a pick-up truck box includes a master and slave assemblies mounted to a transverse section of the sidewall of cab and spaced-apart from each other. Each assembly has an engagement member pivotable between an operative position in which the engagement member extends beneath an inwardly extending flange of the sidewall of the truck box and abuts the undersurface of the flange, and an inoperative position in which the engagement member clears the flange. A set of worm and worm gear is provided in the master assembly and a worm gear shaft extends through the master and slave assemblies to drive the rocker members in the pivotal movement. The clamp assembly is operated using a rotating tool from inside of the cab so that unauthorized removal of the cab from the truck is prevented. The use of the clamp assembly not only advantageously reduces the labour required to secure the cab to the truck box but also permits, in a limited extent, a discrepancy between the truck box and the cab in instant deformation.

Title: Method and apparatus for data compression
Inventor: BOOTH ROBERT CHARLES
IPC: H03M7/30
Filed: 2000-04-10
Granted: 2009-06-23
Abstract: A method and apparatus for compressing Internet protocol messages, such as HyperText Transport Protocol (HTTP) messages. Codewords (225) are provided for commonly occurring HTTP data elements, such as request lines, header lines, status lines, or portions thereof, such as method fields, URL fields, version fields, and status codes or messages. The codewords are used to provide a compressed HTTP message with a reduced amount of data relative to ASCII coding. If other data is included with the message, such as an entity body (e.g., a requested object such as an HTML  page), the other data can be coded separately (215) and recombined (230) with the codewords for the HTTP data elements. The codewords may have reserved bits for providing specific information about the message. The amount of data that must be communicated, e.g., to or from a subscriber terminal (150), is thereby reduced. A message handler (340) decodes and processes the codewords.  A compressed message handler (410) can be provided that processes/renders the compressed HTTP data (e.g., codewords) directly without decompressing them. The system is compatible with other compression techniques to provide even greater compression.
