Abstract: A multi-handled bag is provided. The multi-handled bag may include a first wall, a second wall, a first gusset, and a second gusset that cooperate to form at least a portion of a cavity. The multi-handled bag may also include one or more intermediate seals that extend along the full width of the bag. A variety of end seals can also be used, including tack seals and seals that only extend along a portion of the width of the bag.

Abstract: Bags including tear lines are provided. The tear lines may include a series of perforations having alternating cut and uncut segments. The tear lines may also include two or more portions. The portions of the tear lines may have different shapes and/or characteristics. In some instances, the tear strength of a portion of the tear line disposed in a flap region is lower than the tear strength of a portion disposed in a body region of the bag.

Abstract: A bag including a handle disposed through a reinforcement member is provided. A handle indicator can be disposed on the bag at a position adjacent the handle or around a portion of the handle. The handle indicator can also communicate a position of the handle to a user. Bags including two or more handles, reinforcement members, and handle indicators are also provided.

Abstract: A water well bailer. In one embodiment, the bailer includes a tubular housing composed of any polymer used as a plastic, such as, polyethylene, polypropylene, polystyrene, polyesters, polycarbonate, polyvinyl chloride, nylon, poly(methyl methacrylate), polytetrafluoride, polyacrylonitrile, or chemical derivations there of for storing within the housing a sample of well water. A texture may be on the housing. The texture of the bailer reduces the surface area of the bailer in contact with the inside wall of a water well such that the bailer does not stick to the wall of the water well during incidental contact. The reason a bailer sticks to the side of a well is due to adhesive and cohesive forces acting between the well wall and the bailer.

Abstract: To protect the collimator of a transferred plasma arc torch from premature failure due to corrosion, an anti-corrosive covering is applied on the exposed face surface and a portion of the inner exit bore of the collimator. The specification describes several methods for producing the collimator for a plasma torch having an anti-corrosive coating or cladding on the exposed surfaces thereof, including electroplating, electroless plating, flame spraying, plasma spraying, plasma transferred arc, hot isostatic pressing and explosive cladding.

A texture may be on the housing. The texture of the bailer reduces the surface area of the bailer in contact with the inside wall of a water well such that the bailer does not stick to the wall of the water well during incidental contact. The reason a bailer sticks to the side of a well is due to adhesive and cohesive forces acting between the well wall and the bailer. Adhesive and cohesive forces are generated between the bailer and well wall because of humidity and condensation of water on the well wall, and water on the outside of the bailer after initial contact with groundwater.
