Abstract: A system for treating influent liquid includes a treatment module having an elongated member arranged in a predetermined configuration. The elongated member has a core structure wrapped in a fabric configured for the passage of the influent liquid therethrough. Filter field medium is disposed about open areas defined by the predetermined configuration of the elongated member and is configured for receiving the influent liquid from the elongated member and passing the influent liquid therethrough. A bladder containing the treatment module has an outlet for providing treated influent liquid passing through the filter medium. A distribution conduit is coupled to the bladder and has an outlet for distributing the influent liquid to the elongated member.

Abstract: A modular subsurface sewage disposal and wastewater treatment system is presented for treating effluent from a septic tank. The system includes an elongated member, leach field medium and at least one pipe. The elongated member is arranged in one of a serpentine or a ladder-shaped configuration and includes a core wrapped in a fabric. The medium is disposed about open areas in the configuration. The pipe uniformly distributes effluent from the septic tank to the elongated member. In one embodiment, the core is a pliable plastic membrane and the fabric wrap is a non-woven fabric. In one embodiment, the elongated member is disposed in a box and retained by an adhesive to permit ease of manufacture, shipping, and installation. In another embodiment, the elongated member is disposed in a rigid or semi-rigid frame defining channels retaining the elongated member. The frame is detectable by a non-invasive above surface detector.

Abstract: A modular, portable treatment system (1300) is presented for treating influent liquid (80). The system includes a treatment module (10), a bladder (1310) containing the treatment module, and a distribution conduit (42) coupled to the bladder. The treatment module includes an elongated member (20) arranged in a predetermined configuration (300, 400) and filter field medium (51) disposed about open areas (50-66, 450-466) defined by the predetermined configuration of the elongated member. The elongated member includes a core structure (12) wrapped in a fabric (14). The bladder having an outlet (1318) for providing treated influent liquid (80?) from the system. The distribution conduit (42) has an outlet (44) for distributing the influent liquid to the treatment module.

Abstract: A zone heating device has first and second spaced burners for heating first and second spaced sides of a metal plate during forming of a thickened edge along the edge of the metal plate. The first and second burners are elevationally movable by an actuator between first and second spaced transverse positions relative to the sides of the metal plate. An actuator moves the zone heating device along a trackway in directions transverse the plate edge. A fixed guide under the bias of the actuator engages the edge of the metal plate and maintains the first and second burners at a predetermined location relative to the plate edge. A movable guide maintains the first and second burners at another preselected location relative to the plate edge. A control device controls movement of the first and second burners, the zone heating device, and the movable guide in response to preprogrammed instructions. The zone heating device is particularly suited for use on a forming apparatus.
