Abstract: The systems and methods include a feed mechanism supplying multi-strand wire to a coil-spring winder. The coil spring typically has a plurality of turns and is resilient. The multi-strand wire is typically steel, but may be of other suitable material, or a combination of materials. The coil-spring winder receives wire from a spool of wire and forms that wire into a coil spring. Typically, but not always, the coil-spring winder cuts the coil spring to a desired length, and thereby forms a plurality of coil springs of the type that can be employed in mattresses, furniture, car seats, for industrial machines, or for any other application. To feed the coil-spring winder, the systems include a wire holder that supplies the wire to the coil-spring winder along a feed direction. The wire holder is supported for rotation about an axis that may be aligned with the feed direction. The rotation of the wire holder may be substantially synchronous with the formation of the turns of the coil spring.

Abstract: Mattress foundations for supporting a mattress generally includes multiple support units that can be abutting arranged to for the mattress foundation. In one embodiment, the mattress foundation includes at least two support units in an abutting relationship that form a rectangular shape at each end of the mattress foundation and provide a planar support surface having length and width dimensions effective to support a mattress disposed thereon.

Abstract: A fluid pulsating generator utilizes a repeating pulsating component in conjunction with one or more piezoelectric members to generate a piezoelectric affect which creates an electrical voltage. The fluid pulsating generator can be incorporated into a pulsating sprinkler device which produces a continuous pulsating motion which causes the piezoelectric members to deform to generate the piezoelectric effect that produces the electrical voltage.

Abstract: A spring assembly including a helical coil formed from a multi-strand cord.

Abstract: A flame resistant moisture barrier and a mattress having such a barrier and related methods of manufacture provide mattresses, furniture cushions and other products that provide resistance to flame and moisture.

Abstract: A mattress is constructed from a mattress body having an upper and a lower deck, which is preferably pervious to moisture and air. A removable panel, which includes a top layer of breathable fabric, a bottom layer of a fabric that forms a moisture barrier, and a batting layer, is placed on at least the upper deck of the mattress body. The removable panel is removably attached along the perimeter of the deck or decks by a fastener, such as a zipper. The panel can be removed from the deck for cleaning and folded and secured by the fastener in an inverted configuration, with the top layer facing outward.

Abstract: An emitter and hose assembly (10) includes a hose (20) and an emitter (30). The emitter is assembled with a light transmissive cover (40) to an absorptive cover receiving area (77) on a body section (60) by laser welding. The flow path through the emitter (30) is defined by the emitter itself and is not dependent on the inner surface (20a) of the hose (20).

Abstract: A one-sided mattress construction includes a spring assembly with asymmetric spring coils. Only the bottom portion of each spring coil is attached, either to adjacent spring coils or to a bottom surface of the mattress. The top portion of each spring may have a narrowing taper that permits the top to move independent of other adjacent springs.

Abstract: A drip irrigation hose of the continuous emitter type in which the outlets from the regulating passage each comprise a single longitudinal slit. By controlling the length of the slits and the flexibility of the film, water drips from the outlets when the hose is pressurized without clogging when the hose is depressurized. The slits are sufficiently long and the film is sufficiently flexible so the water drips from the outlets when the hose is pressurized. The slits are sufficiently short and the film is sufficiently rigid so the outlets close completely when the hose is depressurized. An outlet forming wheel has a knife blade on its periphery. A backing wheel engages the outlet forming wheel to establish a first nip therebetween. The backing wheel has on its periphery a circumferential slot into which the knife blade fits at the first nip. A rib forming wheel has around its periphery impressions that define a desired track pattern for the ribs.

Abstract: A method of manufacturing a mattress including providing a foam block, convoluting the foam to form a tongue extending longitudinally along the foam block, and removing at least a portion of the tongue, to thereby form a channel within the foam block.

Abstract: An irrigation device, such as a sprinkler, includes an electric generator for generating electricity. The sprinkler includes a nozzle which couples to a fluid conduit, a rotary deflector positioned downstream from the nozzle and within the atmosphere, an electric generator coupled to the rotary deflector, and a frame coupling the nozzle to the electric generator. The rotary deflector rotates about an axis as a fluid stream exiting the nozzle contacts and sprays from the rotary deflector. The rotary deflector and the rotor of the electric generator are coupled to a common axial shaft such that rotations of the rotary deflector translate to rotations of the rotor.

By controlling the length of the slits and the flexibility of the film, water drips from the outlets when the hose is pressurized without clogging when the hose is depressurized. The slits are sufficiently long and the film is sufficiently flexible so the water drips from the outlets when the hose is pressurized. The slits are sufficiently short and the film is sufficiently rigid so the outlets close completely when the hose is depressurized. An outlet forming wheel has a knife blade on its periphery. A backing wheel engages the outlet forming wheel to establish a first nip therebetween. The backing wheel has on its periphery a circumferential slot into which the knife blade fits at the first nip. A rib forming wheel has around its periphery impressions that define a desired track pattern for the ribs.

Abstract: A pressure-compensating drip irrigation hose (10) has a water supply passage (26) and a flow regulating channel (24) smaller than the water supply passage (26). The flow regulating channel (24) comprises at least one inlet section (28), at least one outlet section (32), and at least one nozzle section (34) between an inlet section (28) and an outlet section (32). The inlet section (28) comprises one or more openings (38) connecting the water supply passage (26) to the flow regulating channel (24). The outlet section comprises one or more openings connecting the flow regulating channel (24) to the exterior of the hose (10). Preferably the flow regulating channel (24) further comprises at least one turbulent flow section (30) between an inlet section (28) and an outlet section (32). The nozzle section (34) is preferably between an inlet section (28) and a turbulent flow section (30). A method for making the drip irrigation hose (10) is also provided.

Abstract: A self cleaning drip irrigation hose comprising an elongated strip of plastic film folded longitudinally to form first and second overlapping longitudinal margins. A first longitudinal bead partially seals the overlapping margin. A second longitudinal bead outboard of the first bead partially seals the overlapping margins. The first and second beads have a repeating longitudinal pattern that forms a flow regulating channel and opposing inlets spaced along the length of the first and second beads. Outlets from the flow regulating channel to the exterior of the hose are spaced from the inlets to create a pressure drop across the flow regulating channel. A third longitudinal bead outboard of the second bead completely seals the overlapping margin. The second and third beads form a water access channel to the inlets in the second bead such that the inlets in the first bead when plugged are back flushed by water flow through the inlets in the second bead.
