Abstract: A filtration system is provided with hollow membrane filter elements operable to remove solids, particulate and colloidal matter from a process fluid. Acoustic, vibration and ultrasonic energy may be used to clean exterior portions of the hollow membrane filter elements to allow substantially continuous filtration of process fluids. The filtration system may be satisfactorily used with process fluids having a relatively high concentrations of solids, particulate and colloidal matter.

Abstract: A centrifuge with combinations of multiple features is disclosed. In one aspect, a centrifuge for removing more dense material from a fluid medium includes a fluid separation wall placed within a sleeve. The fluid separation wall rotates around the axis of rotation. A receptacle aids in separation of the more dense material from the fluid medium. The receptacle defined in a part by a respective geometry and a respective shape. An opening extends from the void area to the outer surface to transport the more dense material to the containment zone. An excitation apparatus associated with the receptacle creates a vibration within the receptacle. The centrifuge may further include a valve ring including a valve orifice the valve ring having a first position which blocks the more dense material from exiting the receptacle and a second position that allows the more dense material to move into the containment zone.

Abstract: A filtration system is provided with filter media operable to remove solids, particulate and colloidal matter from a process fluid. Acoustic, vibration and sonic energy may be used to clean associated filter media to allow substantially continuous filtration of process fluids. The filtration system may be satisfactorily used with process fluids having a relatively high concentrations of solids, particulate and colloidal matter.

Abstract: A filtration system is provided with filter media operable to remove solids, particulate and colloidal matter from a process fluid. The filtration system may include one or more porous membranes which are anchored or secured on their periphery with a large open work area operable to remove selected components from the process fluid. The filter media may include an envelope formed from two membrane sheets with a spacer element disposed there between. A chamber or collection zone may be formed within the envelope to receive clarified fluid separated from the process fluid. Alternatively, the filter media may be multiple layers of spiral wound membranes or a roll of membranes.

Abstract: A health potential study and summary makes use of a multiple-page, relatively comprehensive, questionnaire for the individual, an analysis of answers to the questionnaire in readable summary form and an abbreviated life-style resume of the analysis coupled with a visually graphic portrayal of health potential on a graduated scale. The questionnaire is divided into different categories of health affecting subjects arranged so that answers in the form of yes, no, unanswered, or degree rated against a specified rate scale, are placed in a score box adjacent the question. The questionnaire includes an actual food intake diary for a specified period of days and an exercise report. The analysis and appropriate comments are presented in printed form for the respective categories in a manner comparing ideal conditions against actual conditions of the individual where prevailing conditions are picked from the score boxes and commentary and recommendations selected from a data bank according to score.
