Abstract: A dialysis machine allows the independent control of the concentration of at least two ionic substances inside the patient, particularly sodium chloride and sodium bicarbonate, and an ionic substance A not in the dialysis liquid, so the two substances do not mix and precipitate each other out. This control is achieved by precisely controlling the flow rate of the solutions. The flow rate of the perfusion solution (Qinf) is determined as a function of the dialysis performance (D), the concentration of A in the perfusion solution ((A) sol) and the desired concentration in the patient ((A)des), e.g. Qinf = Cl x (((A)des)/((A)sol-(A)des), where Cl is the clarity of the dialysis machine for A extrapolated from the dialysis performance for sodium D. The concentration of sodium in the dialysis liquid is calculated using the formula: (Na<+>)dial = Qinf/D ((Na<+>)des - (Na<+>)sol) + (Na<+>)des where (Na<+>)sol is the concentration of sodium in the perfusion solution, (Na<+>)dial is the concentration of sodium in the dialysis liquid, Qinf is the perfusion flow rate and (Na<+>)des is the desired concentration of sodium inside the patient. The device also contains means of determining the dialysis performance for sodium by successively measuring the conductivity of at least two fluids up- and downstream of the dialysis machine (Cd1in, Cd1out, Cd2in, Cd2out). These give a dialysis performance D = Qd((Cd1out-Cd1in)-(Cd2out-Cdin))/(Cd2in-Cd1in), where Qd is the dialysis liquid flow rate.

Title: Method for producing images of reservoir boundaries
Inventor: GOLDSBERRY FRED L
IPC: G01V1/44
Filed: 1997-08-05
Granted: 2002-06-18
Abstract: A method of producing images of the limits of a geologic reservoir from measurements of fluid pressure in a well controlled to produce from the reservoir at a constant flow rate. The measurements are taken over a period of time, which includes initiation of well flow and recorded in a plot of well pressure v. time. The method includes detecting abrupt changes in slope of the pressure v. time function, where each abrupt change signifies the arrival of a primary shock wave at a discrete section of a boundary limit of the reservoir;  and calculating the minimum radial distance to the discrete section from the well bore as a function of wave travel time. The changes in the slope of the pressure v. time function are used to calculate the curvature of the boundary at the minimum radial distance. The angular disposition of each discrete section or reservoir limit is then adjusted about the origin and adjustably re-positioned on its point of contact with its associated distance radial limits to provide with the other discrete sections a simulation of the reservoir boundary. Observations from multiple wells reduce any ambiguity in the interpretation.
