| 186 | Method and device for filtering a suspension of particles in a liquid | US851750 | 1986-04-14 | US4708801A | 1987-11-24 | Stanislas Galaj |
| In a method and device for filtering a suspension of particles in a liquid the liquid is passed continuously through a porous membrane, particles from the suspenion gradually accumulating on the membrane and clogging its pores. The filtered liquid is caused to flow momentarily in the reverse direction to return the accumulated particles to the suspension and so unclog the membrane. To achieve this the filtered liquid is fed into one end of a conduit wound around an axis and recovered from its other end, and the conduit is rotated about its axis, the speed of rotation gradually increasing, and then suddenly stopped. | ||||||

| 188 | Apparatus for preventing the entry of air into an artificial organ | US191378 | 1980-09-29 | US4345999A | 1982-08-24 | Jan-Erik Sigdell; Gerd Krick |
| Air or gas is prevented from entering into the exchange zone of an artificial organ such as an artificial kidney, dialyzer, or hemofilter. For this purpose a separating path is arranged in parallel with the artificial organ or with the exchange zone or other operative portion of the artificial organ between the liquid inflow and outflow conduits. This parallel path is provided with a high flow resistance for the liquid and with a low flow resistance for the air. Such differential flow resistance may, for example, be accomplished by apertures, gas permeable materials, and eddy chambers. The gas separating path is incorporated as an integral part of the artificial organ or as an integral part of the liquid inflow and outflow conduits. According to several embodiments, an enlargement is provided in the separating path or conduit in which the liquid may "rise and dwell" to enhance air separation before the liquid flows into the operative portion of the artificial organ. | ||||||

| 194 | Method of preventing air from becoming entrapped within a filtration device | US812717 | 1997-03-06 | US6010633A | 2000-01-04 | Peter Zuk, Jr.; Jonathan C. Alt |
| An in-line gravity filtration device for biological fluids such as blood or blood products is disclosed. The device includes a series of channels formed downstream of filtration elements. The channels are defined in cross sectional area by the distance between the filtration elements and their bottoms. The channels are configured to form flow paths to an outlet port so that air within the channels is forced downstream through the outlet port thereby minimizing air being trapped on the downstream side of the device. For optimum performance, the cross section area of a single continuous channel, or the sum of the cross sectional area of parallel channels, leading to a single outlet port, should not exceed the cross sectional area of the outlet port. | ||||||
| 195 | Apparatus and method for membrane filtration with enhanced net flux | US804279 | 1997-03-03 | US5958243A | 1999-09-28 | Darren P. Lawrence; Theo A. A. Hellenkamp |
| A membrane filtration system which uses pump speed controllers to control flow rate and pressure during both the filtration cycle and the backwash cycle. The pump speed controllers operate by changing the frequency of AC current delivered to the pump motors, which changes the flow rate by changing the speed of the pump motor. The speed controllers operate by modulating the pump input power frequency in response to a signal from a flow or pressure signal received from a flow or pressure meter located on a liquid input pipe. This pump speed control method avoids the cyclical dampening patterns observed when trying to adjust pressure and/or flow rates by adjusting regulating valves. The system can also reduce or prevent formation of pressure spikes when switching from a filtration cycle to a backwash cycle, and vice versa. This reduces the likelihood of damage to the membrane from hydraulic pressure pulses. Finally, it offers the flexibility to provide pressure and flow pulses throughout the filtration and backwash cycles. These pulses have been found to dislodge foulants from the membrane while improving the net flux across the membrane, resulting in an increase in system productivity. | ||||||
| 196 | Baffle for conversion of fine bubbles to coarse while filtering with a vertical skein of hollow fibers | US896517 | 1997-06-16 | US5910250A | 1999-06-08 | Mailvaganam Mahendran; Ake Adolf Deutschmann; Wayne Jerald Henshaw; Henry Behmann |
| A filtration device is provided for withdrawing permeate essentially continuously from a multicomponent aqueous substrate containing growing microorganisms in a reservoir. A vertical skein of fiber is scrubbed with coarse bubbles which emanate from a conversion baffle positioned under the skein. The substrate is aerated with fine bubbles in a size range small enough to transfer oxygen to the substrate efficiently. The baffle traps the fine bubbles and converts them to coarse bubbles which are effective to scrub the fibers. In the most preferred embodiment, the finished headers of the skein are derived from composite headers comprising a fixing lamina of resin in which the fibers are potted near their terminal ends, and a fugitive lamina of fugitive powdery material in which the terminal ends of the fibers are potted. The fugitive lamina is removed, preferably by dissolving the powder, e.g. finely divided common salt in water. | ||||||

| A liquid filtration device useable for removing leukocytes from blood contains a first chamber which is in fluid flow relationship with a second chamber. Filtration elements separate the first chamber from the second chamber so that liquid flowing from the first chamber is filtered thereby prior to entry into the second chamber. A passage leads from the second chamber into the first chamber and a hydrophobic filter may be used to prevent liquid from the first chamber from flowing through the passage into the second chamber while allowing air to flow therethrough. An outlet is located in the second chamber, preferably at the bottom thereof. A second outlet may be located within the second chamber and may be placed in fluid flow relationship therewith by a conduit or the like. | ||||||
