摘要： A filtration system is provided that directs a fluid to be filtered through a disposable tubular filtration element, supports the filtration element, and accommodates for "wet growth" of the filtration element. The system operates with an inside-to-outside forced fluid flow through the filtration element and includes a generally cylindrical housing with a fluid inlet and outlet. A perforated outer support screen is mounted within the housing and surrounds the walls of the tubular filtration element with slight clearance. Under the influence of the fluid pressure and the wet growth, the walls of the filtration element bear against the screen. A sealing and support assembly having upstream and downstream fluid guides, each carrying, in a preferred form, a pair of resilient sealing members, is positioned inside the filtration element. A rigid inner member bridges the opposing faces of the resilient member pairs. A rod and nut arrangement draws the flow guides towards one another to apply a longitudinal compressive force on the resilient members caught between a flange on the flow guides and the rigid inner member. This compressive force deforms the resilient members in a radially outward direction to seal the filtration element to the housing and isolate the filtered fluid. In a preferred form, the adjacent faces of each pair of resilient members are aligned with the interior edge of an impregnated end portion of the filtration element. In addition, a tubular prefiltration element may be positioned inside the rigid inner member.

摘要： A tubular element for removing particulate matter and bacteria of dimensions in excess of a predetermined value from a fluid flowing from the interior to the exterior of the filtration element has a first inner layer of a highly porous material that has a low coefficient of sliding friction, and a second layer of a microporous filtration material having pores of substantially uniform size. The element may include an outer support layer of a porous material that is not subject to shedding. In a preferred form, the inner layer is formed from a high wet strength paper, the microporous filtration layer has sufficiently small pores to remove all bacteria from the fluid, and the outer layer may be a fine porous plastic sheet material or a high wet strength, high porosity paper that is impregnated with the polymeric material that forms the microporous filtration material. The fine pore structure of the outer layer supports the fragile filtration layer. In a preferred form, both ends of the tubular element are impregnated with a suitable sealing material such as a polyurethane potting compound. The ends are preferably dipped in the sealing material to a predetermined depth. When cured, these end portions provide additional mechanical support for the tube ends and block the passage of particulate matter and bacteria past the filtration layer at its edge. A fabrication process for the filtration element that does not damage the fragile microporous filtration layer involves helically wrapping the inner layer on a fixed mandrel to act as a carrier, and helically wrapping an overlying layer of the microporous filtration material. If an outer layer is used this is wrapped on the microporous material. All layers move in unison along the longitudinal axis of the mandrel. Each layer is self-overlapping and at least the filtration layer is sealed in the area of the overlap.

摘要： A novel process for packaging goods within stretch-type plastic films. The process comprises the steps of preforming the package elements so that on-line sealing and long cooling cycles are not necessary during rapid packaging procedures when the film is extended under high stress. The required extension is achieved by the use of film-band spreading means which have low friction surfaces thereby minimizing any local stress on the expanding package material.

摘要： An anti-short bushing, for use between a tubular metal sheath and an electrical conductor carried within the metal sheath, comprising a tubular insulative unit configured to be inserted between the sheath and the conductor. The tubular insulative unit is formed as a single molded piece having three connected segments. Two of the segments are generally semi-cylindrical and each has a shoulder projecting radially therefrom at one end. The two segments are connected by an elongated hinge which permits them to be folded relative to one another to form a tubular configuration with their shoulders forming a partial circumferential shoulder. The third segment is connected to the elongated hinge by a second hinge to permit the third segment to be rotated to project radially outwardly so as to form with the two shoulders of the other two segments a complete circumferential shoulder.

摘要： A device is described which provides a totally enclosed and secure environment for the culture of cells and for the production of biologicals, pharmaceuticals, and other cell-derived products of commercial value. The device comprises several modules of differing functions: regulating the cellular growth environment, providing a suitable cell growth substrate or environment, or separating of desired product form interfering substances. Each module comprises a series of membranes separated by a solid support material which is channeled to provide a series of parallel capillaries for the flow of nutrients, environmental regulating fluids, or gas exchange. The structure and composition of the separating membranes limits the nature, rate, and size of the particular material exchanged across an individual membrane into or from an adjacent compartment. The capillaries are so dimensioned that the nutrients and gases are diffused over distances typical of human tissue.
