Abstract: A valve assembly includes a valve body and a seat defining an outlet. The valve assembly also includes a float disposed inside the valve body and is movable between a first position and a second position relative to the valve body. The valve assembly further includes a support coupled to the float and is movable with the float between the first and second positions. The valve assembly also includes a sealing member attached to the support and has an engagement portion spaced from the seat when the float is in the first position and engaging the seat when the float is in the second position.

Abstract: A co-injected fitting has a core made of recycled or reground PVC and ABS, which is less expensive and to which, in some embodiments, a blowing agent, such as azo and/or sodium bicarbonate, can be added to lower the weight. The fitting includes a skin on opposite sides of the core forming the internal side of the fitting and the external side of the fitting, respectively, in concentric relationship to the inner core. Such fittings may also include a strengthening core material, such as polycarbonate, to provide a stronger pipe fitting which likewise can be co-injection molded.

Abstract: The present invention is directed to a combination adjuvant comprising an ammonium sulfate fertilizer impregnated with a drift reducing agent. The drift reducing agent is preferably polyacrylamide. Anti-caking and drying agents are preferably added to the combination adjuvant to provide ease of use and prevent caking and agglomeration of the adjuvant. The combination adjuvant is formed by mixing a liquid drift reducing agent with dry ammonium sulfate granules. Any additional agents are added and mixed with the drift reducing agent and ammonium sulfate. Because each granule comprises approximately the same amount of drift reducing agent, the composition of the combination adjuvant is uniform, even after storage and transport.

Abstract: A system for automatically positioning a plurality of tool-holding carriages along an elongate guide member utilizes a single drive member to move all of the carriages simultaneously. The carriages each have clutches for selectively engaging or disengaging the drive member so that the carriages can be moved relative to each other by the drive member, and can be moved simultaneously in opposite directions along the guide member if desired. The drive member is capable of moving each carriage throughout its respective maximum range of movement with a continuous motion, without any reversal of the drive member or any disengagement of the respective carriage from the drive member. Each carriage has an electrically-powered position sensor capable of transmitting different discrete signals for different positions of the carriage so that it provides absolute indications of position rather than indications which are relative to some reference position.
