Abstract: A fluidized bed combustion method for burning wastes using a fluidized bed furnace without being affected by fluctuation of the quantity and quality of wastes fed into the furnace, if any, thereby preventing CO gas, etc. from discharging out of the furnace, is provided.  This furnace comprises a number of air-diffusing tubes for feeding a primary air to the fluidized bed, paralelly arranged with each other at the bottom of the fluidized bed, and a free space part formed above the fluidized bed for burning unburnt matters with a secondary air, said air-diffusing tube having a number of nozzles provided along the axis of the tube and a primary air control means including an open-close damper for controlling the quantity of air to be fed.  And the method is carried out by feeding said primary air into the fluidized bed through said air-diffusing tubes one after another according to a predetermined open-close pattern by means of said primary air control means so that the ratio of the air quantity Uo to the minimum fluidizing air quantity Umf (Uo/Umf) is in the range of 1.4 to 4 when said damper is opened and in the range of 0.5 to 2 when said damper is closed, and at intervals of 1 to 10 seconds, preferably 2 to 10 seconds, and 10 to 100 seconds, respectively.

Title: Method of sampling, and sampling device
Inventor: VAN NIEKERK JOHANNES A
IPC: G01N1/10
Filed: 1991-03-01
Abstract: A B S T R A C T            In sampling grain offered in bulk as shown at 40, a sampling device 10 is inserted vertically downwardly into the grain.  The device 10 has an inner tube 12 having openings 18 in series along its length and a sleeve 14 which is open bottomed and axially slidable over the tube.          During insertion, the sleeve 14 covers the openings 18.  To obtain a sample, the sleeve 14 is slowly slid upwardly relative to the inner tube thus progressively to expose the openings 18 from the bottom upwardly.   Grain flows laterally via the openings 18 into the tube, which fills from the botom.   Practically no vertical displacement of kernels takes place,  thus ensuring that a representative sample is taken at all levels.  Ultimately, the sleeve 14 is slid downwardly to close the openings 18.  The device, containing the sample, is withdrawn.

Title: Downhole reciprocating pump and components therefor
Inventor: MASON LEONARD V
IPC: F16K17/12
Filed: 1991-04-12
Abstract: "DOWNHOLE RECIPROCATING PUMP AND COMPONENTS THEREFOR"               ABSTRACT OF THE DISCLOSURE           A downhole reciprocating pump is provided having novel check valves and a novel plunger.   Each check valve has a generally cylindrical  valve  member having  a  smooth-surfaced tapered lower end adapted to seat in a tapered seat.  The upper portion of the valve member carries outwardly protruding, spaced apart vanes disposed at an acute angle relative to the axis of the valve member.  Fluid can move past the valve member through the channels between the vanes.  Interaction between the fluid and vanes causes the valve member to spin.   By combining the downwardly tapered sealing surfaces with the  spinning valve member, sand is kept clear of the sealing surfaces and erosion, arising from the surfaces being propped apart, is reduced.  The plunger is equipped with oppositely directed, upper and lower pressure-driven metal seal rings.   Each seal ring has a thin, axially  extending,  annular  lip  that  is  flexed  by  downhole pressure into sealing contact with the inside surface of the pump barrel.  The seal rings provide the plunger with effectively an interference  fit,   thereby  eliminating  the  problems  that characterize plungers having a clearance fit with the barrel.

Title: Method of preventing formation of hydrates in flowing hydrocarbons under subsea piping of same and a subsea plant for processing of a well to prevent hydrate formation
Inventor: CHRISTENSEN JAN S
IPC: F15D1/02

Abstract: ABSTRACT OF THE DISCLOSURE.            Method  of  preventing  formation  of  hydrates  in  flowing hydrocarbons under subsea piping of same and a subsea plant for processing of a well flow to prevent hydrate formation.            Formation of hydrates is to be prevented in subsea pipelining of hydrocarbon flows by establishing the phase diagram for said flows including a hydrate line.  The hydrocarbon flow is separated under a pressure at which light hydrocarbons boil off the liquid phase and enters the gas phase to such an extent that hydrates will not be formed or substantially not be formed in the liquid phase, determined by the composition of the flow of hydrocarbons.   The gas phase is processed according to known methods so that formation of hydrates is prevented during the subsequent piping.  A subsea plant for processing of a well flow to prevent formation of hydrates during  the  subsequent  piping  includes  a  separator  for separation of the well flow into liquid and gas, connection means  for  connection  of  the  separator  to  a  well  flow pipeline,  a pump unit  including a pump with motor and a compressor  unit  comprising  a  compressor  with  motor,  and fluidum carrying lines between the separator and the pump resp.  the compressor  and a pressure  line from pump resp. compressor, connected to the conveying pipelines and a choke device  in  the  well  flow  pipeline  for  reduction  of  the pressure in the separator and a control device for adjustment of the choke device in accordance with the pressure desired in the separator.

Abstract: 2054198 9115068 PCTABS00007 A spread spectrum communications system uses a leaky coaxial cable for cost effective radio communication in enclosed areas. The system includes radio units (12) which communicate with a transceiver, the transceiver being coupled to the leaky coaxial cable (16). Full-duplex communication includes a first frequency band (F1) for transmitting spread spectrum signals from the transceiver to the radio units at power levels which are adjusted to take advantage of the losses associated with leaky coaxial cable, and a second frequency band (F2) for transmitting spread spectrum signals from the radio units to the transceiver at the more conventional spread spectrum power levels specified by the FCC. The present invention employs this split band configuration to accommodate communication over leaky coaxial cable without expensive and bulky filtering for isolation between the transmit and receive signals.

Abstract: ABSTRACT OF THE DISCLOSURE            In a rotating impeller of a centrifugal pump, a fluid is allowed to leak at angle across the impeller vanes between adjacent internal channels of the impeller, at reduced rates of flow.  Such action disturb the homogenous velocity pattern of the fluid inside the channels by causing flow detachment from the trailing surfaces of the impeller vanes and a severe internal circulation of the fluid.  This in turn results in reduced pump discharge pressure and a much desirable reduction in energy consumption.
