Title: Process for accurately regulating the low alumina content of an igneous electrolysis cell for aluminium production
Inventor: LEROY MICHEL
IPC: C25C3/20
Filed: 1986-05-05
Granted: 1989-07-27
Abstract: A process is disclosed for accurately maintaining a low alumina content of between 1 and 4.5% in a cell for the production of aluminum by electrolysis in the Hall-Heroult process. According to the invention, a control parameter P=-1/D(dR1/dt), is determined, wherein D is the variation in the alumina content of the electrolytic bath in % weight per hour, R1 is the internal resistance of the cell, and t is the time. A series of operations is then carried out in a repeated cycle, starting with the cell being fed alumina at a nominal rate which is substantially equal to the quantity consumed by electrolysis. At periodic intervals, an over-supply of alumina is added in order to enrich the bath, and the over-supply is continued for a preset time during which dR1dt is negative. The feed rate is then reduced to less than the nominal feed rate, during which time dR1dt passes through zero to become positive and the regulation parameter P, the value of which tends to rise, is measured often. The successive values of P are compared with a required preset value Po. As soon as P equals Po, the feed rate is returned to the nominal feed rate and a new cycle is recommenced.

Abstract: A continuous flow peritoneal dialysis system and process is disclosed which includes a source of sterilized peritoneal dialysis system in the form of a gravity feed head vessel (32). A bypass valve (34) connects the head vessel to an inflow/outflow directional valve 40 which controls the inflow and outflow of the sterilized dialysis fluid to a peritoneal catheter (12). The peritoneal catheter is implanted into the peritoneal membrane (14) of the peritoneal cavity (15). A connectable/disconnectable inflow line (42) and outflow line (48) are connected to an inflow catheter (44) and an outflow catheter (46), respectively, of the double peritoneal catheter (12). A pressure monitor (50) in the outflow line (48) monitors the pressure within the cavity (15) and adjusts the inflow and outflow accordingly to maintain a predetermined volume and pressure of dialysis fluid in the cavity to maintain the membrane (14) properly distended at all times for maximum dialysis efficiency and patient comfort. Secondarily, an outflow monitor (54) monitors the outflow and if need be, increases or decreases the inflow to the directional valve (40) by controlling a bypass valve 34. Control of the level of dialysis fluid in the head vessel (32) is maintained by a level monitor (38) which also can operate the bypass valve (34) to bypass fluid to a drain tank (36). Sterile dialysis fluid flows through the cavity (15) in an open single-pass circuit and flows into the disposal and drain tank (36) upon passing through the cavity. Another embodiment controls solely on the basis of volume rather than on the combined basis of pressure and volume.
