Method and equipment to perform controlled access to the projected location inside a storage tank, while it is operated, idle, or undergoing maintenance, to conduct an internal service from outside. This intervention from outside can be performed through an access opening in the wall or roof of the tank. In addition to other innovations, a new coiled tubing (CT) solution for multiple 3D positioning arrangements outside and inside the tank is provided for both positioning, inserting, remote control, and withdrawing the CT with the active head for the controlled accessing of the target area.

A coating composition is provided that is useful in coating metal substrates such as interior and/or exterior surfaces of food or beverage cans. In preferred embodiments, the coating composition is formulated using a physical blend of a preformed_resin system and an alkali-soluble resin additive.

This invention provides a polymer that is useful in a variety of applications, including as a binder polymer of a coating composition, and especially a packaging coating composition. Packaging articles (e.g., containers) comprising the polymer and methods of making such packaging articles are also provided.

There is described an acrylic polyester resin, obtainable by grafting an acrylic polymer with a polyester material. The polyester material is obtainable by polymerizing (i) a polyacid component, with (ii) a polyol component. At least one of the polyacid component and/or the polyol component comprises a monomer having an aliphatic group containing at least 15 carbon atoms. At least one of the polyacid component and/or the polyol component comprises a functional monomer operable to impart functionality on to the polyester resin, such that an acrylic polymer may be grafted with the polyester material via the use of said functionality. Also provided is an aqueous coating composition comprising the acrylic polyester resin and a packaging coated with the composition.

By coating an inner surface of a preform, in which at least an inner surface is made of polyester and which has transparency, with a coating layer, which has elongation capacity and water insolubility, the inner surface of the preform is protected against a pressurized liquid by the coating layer when the pressurized liquid is supplied to the preform, and occurrence of cloudiness on an inner surface of a container after molding is prevented even in a case where a liquid having properties of eroding polyester and causing cloudiness on a polyester surface is used as the pressurized liquid during liquid blow molding.

A method for treating a substrate with a volatile liquid, crop-preservative formulation includes transporting a predetermined quantity of the formulation from a reservoir to an injection device and applying the predetermined quantity to the substrate. The substrate may thereafter be in proximity to a crop to be treated by the vapor from the formulation. The substrate is most conveniently a portion of a container in which the crop is stored or shipped.

Processing an evacuated blood sample collection tube or other vessel by plasma enhanced chemical vapor deposition to apply a tie coating or layer (289), a barrier coating or layer (288), and optionally one or more additional coatings or layers. The tie coating or layer of SiOxCy is applied under partial vacuum and, while maintaining the partial vacuum unbroken in the lumen, the barrier coating or layer is applied. Then optionally, while maintaining the partial vacuum unbroken in the lumen, a pH protective coating or layer of SiOxCy can be applied. As a result of this processing, a coated vessel is produced having a lower gas permeation rate constant into the lumen than a corresponding vessel made by the same process except breaking the partial vacuum in the lumen between applying the tie coating or layer and applying the barrier coating or layer. Retention features are also described for keeping the vessels stoppered during exposure to reduced ambient pressure.

Beverage containers and methods of coating are provided. The beverage containers include a metal substrate that is at least partially coated with a coating prepared from a composition that includes a binder system, a cross linker, and a catalyst.

An improved can drying and curing technology is provided.

A light weight component, the light weight component including: a metallic foam core formed into a desired configuration; an external metallic shell applied to an exterior surface of the metallic foam core after it has been formed into the desired configuration; an inlet opening and an outlet opening formed in the external metallic shell in order to provide a fluid path through the metallic foam core; and a thermoplastic material injected into the metallic foam core via the inlet opening.
