| Number | Title | Issue Date |
| 4846976 | Treatment of emulsions A filtration system for treating an emulsion containing water, an oil or a fat, an emulsifying agent and insoluble solid material (such as a maritime oil emulsion containing an anionic detergent and the solid, greasy calcium salt of the detergent) has a f... | 07/11/1989 |
| 4822863 | Sulphuryl chloride/polyamide derivative Aliphatic polyamides are reacted on their surfaces with sulphuryl chloride, either neat or in solution in paraffins or cycloparaffins to give reactive intermediate whcih may convert into a support capable of reaction with antibodies or enzymes by providin... | 04/18/1989 |
| 4816160 | Cooling hollow fibre cross-flow separators A method of treating a heated liquid suspension, which entails: (a) applying a liquid suspension to elastic, microporous, hollow fibres within a shell or housing, and (b) discharging solids retained on or in the fibres by applying to the fibre lumens a pressur... | 03/28/1989 |
| 4814083 | Altering pore size distributions Pores that are smaller than or larger than a predetermined range of pore sizes in a porous membrane barrier are blocked with a controlled porosity blocking agent. The pores are first filled with a liquid so as to remove any air therein and then subjected ... | 03/21/1989 |
| 4793932 | Variable volume filter or concentrator A concentrator for concentrating the fine solids of a liquid feed suspension has a shell within which there is a bundle of microporous fibers. Pressurized feed suspension is introduced through an inlet and passes over the external walls of the fibers with... | 12/27/1988 |
| 4781873 | Reversed phase membranes A reversed phase analogue of at least part of a first membrane having substantially interconnected pores is formed by first filling at least some of the pores of the first membrane with a fluid that will form the analogue membrane and then forming the ana... | 11/01/1988 |
| 4767539 | Cleaning of hollow fiber filters utilized in lumenal gas flow A method of cleaning a filter having a plurality of elastic, porous hollow fibers with lumens within a shell or housing and in which filtration is carried out by applying a liquid suspension feedstock to the outer surface of the fibers whereby a portion o... | 08/30/1988 |
| 4743378 | Rapid vapor transport through unwetted porous barriers A method of increasing the rate the transport of volatiles through porous barriers (13) such as membranes consists of subjecting the porous barriers (13) to a vacuum for sufficient time to remove any permanent gas from the pores (V), admitting a non-wetti... | 05/10/1988 |
| 4661526 | Cross linked porous membranes A polymeric porous membrane having a matrix made from an aliphatic thermoplastic polyamide or from an aliphatic thermoplastic polyamide/polyimide copolymer which has both relatively non-crystalline and relatively crystalline portions. The pores in the mem... | 04/28/1987 |
| 4655927 | Separating oil emulsions Water is separated from an oil emulsion containing a surface active agent by passing the emulsion through a polymeric porous membrane cross-flow ultra-filter. Either the oil emulsion feedstock or the membrane is treated with a hydrophilic colloid so that ... | 04/07/1987 |
| 4613625 | Substituted aliphatic polyamide porous membranes Aliphatic thermoplastic polyamide porous membranes are reacted with an acid halide of basicity above one to provide acid radicals within the membrane. The acid halide may be derived from an aromatic carboxylic acid or an aromatic derivative of a chlorosil... | 09/23/1986 |
