Granted: 1991-07-23
Abstract: PROCESS AND APPARATUS TO REMOVE SEPARATED WATER FROM        CONTAINED HYDROCARBON FUEL     ABSTRACT OF THE DISCLOSURE A highly hydrophilic material that does not absorb hydrocarbon fuel is contained in a fabric tube, lowered by a drawstring to the bottom of a fuel container, there maintained until water at that position is extracted by the hydrophilic material and the fabric tube thereafter removed for disposition.  The hydrophilic material is preferably a graft polymerized starch such as polyacrylanitrile or gelable polysaccharide such as agarose.  The fabric container is densely woven with fine intracies to contain the hydrolyzed hydrophilic material during placement and especially against fluidic heads during extraction.  The fabric material is coated with polymeric material insoluble in hydrocarbon fuel but soluble in water, such as polyvinyl alchohol, to keep the fabric free of hydrocarbon encroachment during initial placement.  Static electricity is removed from the apparatus by coating the fabric material with antistatic agents of a surfactant nature and providing an electric conducting system which is externally grounded.  The fabric tube is weighted by dense particulate material such as sand, which is distributed with the hydrophilic material for maximum operative efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE:               The incinerator is made of a loading member, a burning chamber, a combustion chamber and a duct member having a restricted dimension for connecting the burning and the combustion chambers. The loading member is an upstanding cylinder for receiving the waste mate-rial and droping it in the burning chamber. The burning chamber has a floor located at such a distance from loading cylinder so as to ob-tain the spreading of the waste material in a generally frusto-conic-al shape. A peripheral wall around the burning chamber is dimensioned to leave an air space around the frusto-conical shape. An air intake in the peripheral wall provides a circulation of air in the air spa-ce. The duct members are diametrically opposed to the air intake and funnel the hot fumes from the burning chamber to the combustion chamb-er. The concentration of the hot fumes in the duct members considerab-ly raises the temperature in the duct members for a practically com-plete decomposition of the products in the fumes.

Title: Enhanced oil recovery with hydrophobically associating polymers
Inventor: BOCK JAN
IPC: E21B43/22
Filed: 1987-12-11
Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE         This invention  relates  to a  method  for enhanced recovery of  petroleum from a  subterranean oil-bearing  formation.   More  particularly,   this invention relates to secondary or tertiary  recovery of oil employing  a polymer-thickened aqueous  drive fluid. The  polymeric  viscosifier  for  the  drive fluid is selected  from a  class of  hydrophobically associating, water soluble  polymers containing  one or more water soluble monomers and a water insoluble monomer  group.   The   water  soluble  groups   are acrylamide and a salt of acrylic acid and the  water insoluble group is a higher alkylacrylamide.   These polymers, when dissolved in  an aqueous brine  solu-tion, have the ability to substantially increase the viscosity of the  aqueous solution.  The control  of displacement fluid mobility results in more  uniform sweep efficiency  and  improved  oil  recovery.   In addition, aqueous solutions of these hydrophobically associating      polymers      exhibit      enhanced viscosification, reduced salt sensitivity and  other desirable rheological  properties  found  useful  in chemically enhanced oil recovery processes.

Abstract: ABSTRACT OF THE DISCLOSURE      A segment descriptor unit (SDU) includes a divided random  access  memory  (RAM),  a  content  addressable memory  (CAM)  and  decoder  circuits  interconnected  for performing  dynamic and  static  address  translation operations within a minimum of  chip area  and power. The CAM is arranged to store a number of entries which include   segment   number   and   validity   information associated  with  a  corresponding  number  of  segment descriptors.   The RAM contains locations allocated for storing  segment  descriptor words  (SDW's)  and working data.  Each SDW is logically divided into two fields, a static translation word  (STW)  field containing all of the  bits  required  for  performing  a  static  address translation operation and an access control word  (ACW) field containing all of the bits required for verifying compliance with system security.   The bits of each STW and ACW are stored in alternate bit positions of  the SDW locations.   Each pair of RAM bit locations couple to  a  common  read/write  amplifier  and  multiplexer circuit.   Through the use of microinstruction commands coded   to   specify   different   address   translation functions,  the STW and ACW fields selected by the CAM are read out from RAM during different intervals for carrying out the steps of those operations.

Title: Energy conservation apparatus

Granted: 1992-02-18
Abstract: ABSTRACT      Wind energy conversion apparatus comprises vertical endless travelling belt means and a plurality of inter-spaced hydrodynamic foil members mounted thereon.  Passage of fluid, i.e. wind, over the foil members creates lift forces thereon serving to drive the endless belt means about belt circulating parts.  The foil members may have a fixed angle of incidence with respect to the belt runs i.e between the circulating parts at the top and bottom of the endless belt means; or they may be of variable pitch.  In one embodiment the belt means comprises two separate endless belts the foils are carried on arms which have pivotal connections with both belts; and a tension spring connects the belts.  A belt circulating part, the lower wheel is coupled to a rotary load, an electric generator. Aerodynamic lift on the foils drives the belt and, by the spring connection, the belt and the rotary load.  The foil angle of incidence is determined by the lift and the spring reaction.     Background to the Invention This invention relates to energy conversion apparatus and is primarily concerned with energy conversion apparatus operable by a flow of fluid.     The economic viability of any wind energy conversion project is, in common with any other prime source energy conversion project, determined by the ratio of, on the one hand, the capital costs involved in the construction of the wind energy conversion apparatus plus the costs incurred in its maintenance during the productive life thereof, and on the other the total energy produced by the apparatus during that period.     Conventionally, windmills of a wide range of differing forms are employed in wind energy conversion.  One might think, at first, that a large windmill would be more cost effective than two smaller ones sweeping an equivalent area.  In practice this turns out to be true only up to a certain point, a point determined by other factors notably wind behaviour.     The rate of energy conversion by a windmill is a function of the area swept out by the blades of the windmill; but the dynamics of the windmill is a function of the blade mass, that is to say the cube of the blade dimensions.  So the rotor mass increases disproportionately with size to the energy produced. This translates to disproportionately higher costs to cope with the dynamic loads generated.     It is an object of the present invention to provide wind energy conversion apparatus which may avoid the problems and, hence, the economic limitations of the windmill, as mentioned above, but more generally to provide a novel form of energy conversion apparatus operable by flow of a fluid with respect thereto.
