Abstract: A liquid storage tank broadly comprising a drum, a bottom chime, and a top chime. The bottom chime and top chime each include drum engaging geometry for positively connecting the chimes to the drum and retaining the chimes on the drum when the drum is holding liquid and subjected to lifting forces. The top chime also includes forklift openings and alignment and anti-rotation geometry configured to prevent the top chime from rotating relative to the drum when the drum is lifted via a forklift fork extending through the forklift openings so that the forklift fork does not damage a top wall or bung openings of the drum.

Abstract: A method of forming a molded part in a mold having an ejector assembly. The ejector assembly includes an ejector arm and mounting structure. The ejector arm has a first end with a tongue that extends partially into a cavity of the mold and an opposite second end with a handle that extends outwardly from the mold cavity. The mounting structure pivotally mounts the ejector arm to the top portion of the mold so that the ejector arm may be pivoted between an operating position and an ejection position.

Abstract: A combination flow control and reverse flow check valve controls the flow of fluid in a desired downstream direction and limits undesired backflow of liquid in an upstream direction into a fluid source such as a reservoir. The flow control and reverse flow check valve may include a housing having a fluid conveying channel with an upstream end configured for mounting to the liquid source and a downstream end for discharging fluids, a flow control valve positioned between the ends, and a check element positioned in the channel between the flow control valve and the downstream end. The check element is advantageously positioned between the flow control valve and the downstream end of the housing to prevent possible contaminants in a backflow liquid from reaching the flow control valve.

Abstract: A cable reel assembly includes a fluted drum; a pair of circular flanges removeably attached to opposite ends of the drum; and a number of elongated rods that connect the flanges to the drum. The drum and flanges are preferably rotationally molded of synthetic resin materials and are partially hollow so as to minimize their weight.

Abstract: An interlocking support foot and a container assembly including the support foot permits the support foot to be threaded onto a container but resists loosening of the foot by reverse rotation of the support foot once installed onto the container. The support foot is preferably molded of synthetic resin as a unitary member including a body, a threaded connector and at least one, and preferably a circular array of teeth radially spaced from the connector. The container is complementally configured to include a plurality of support areas for threadably receiving the support foot and provided with a threaded receiver and a radially spaced notch. When the support foot is installed on the support area of the container, the tooth engages the notch and resists reverse rotation of the foot.

Abstract: A slide valve assembly is provided for selectively dispensing dry goods from a hopper. The slide valve assembly is readily attached and detached from the hopper and is readily disassembled and reassembled to facilitate cleaning and/or servicing. Preferably, the slide valve assembly includes a panel secured to spaced support rails, a movable valve panel for opening and closing of the dispensing portion of the hopper, and a collar retainer for releasable attachment to the dispensing portion of a hopper. The slide valve assembly may be attached, detached, assembled, and disassembled substantially without the use of tools or separate fasteners, to minimize the risk of creating a contamination hazard for the goods dispensed from the hopper, while still allowing for secure attachment to the hopper.

Abstract: A protection and containment system for co-packaged containers is provided which includes a hollow primary container, a top protector complementally configure to fit atop the primary container, and at least one retainer coupled to the top protector for holding a secondary container. The primary container has a circumscribing upright sidewall and an opening configured for receiving material to be stored in the container. The top protector includes a side wall and at least a pair of spaced-apart opposed risers, most preferably provided as one of four corner modules, the risers extending upwardly from the primary container above the opening and presenting a gap between the risers which is sized and configured for receiving the secondary container. Several retainers can be provided, either to hold the secondary containers in different gaps, or provided in tandem to hold two secondary containers adjacent to one another in or proximate a single gap.

Abstract: A combination flow control and reverse flow check valve provides a compact valve unit for controlling the flow of fluid in a downstream direction and limiting undesired backflow of liquid into a source such as a reservoir. The flow control and reverse flow check valve may be provided as a unitary member having a housing with an upstream end configured for mounting to the liquid source, a fluid conveying channel within the housing, and a check element positioned in the channel between the flow control valve, such as a ball valve, and a seat which is complementally configured with the check element to normally seal against backflow. A blocking element may be provided to prevent interference of the check element with the operation of the flow control valve while permitting liquid to flow in an intended downstream direction.

Abstract: A torque arm restraint is provided with a body having a bore including an axis and an arm extending from said body transversely to the axis and is adapted for resisting torque applied to the fitting of a liquid storage tank, and is configured either for mounting on a fitting or as a component of the fitting such as an outlet fitting mounting a pipe and extending from the wall of the tank. A tubular body permits passage of instrumentation or liquid therethrough and the arm may have an abutment surface positioned proximate the inside surface of the tank wall, either in engagement or in spaced relationship, whereby the arm resists torque applied to the fitting exteriorly of the tank. The body may include an attachment member which is adapted for mounting to a tank fitting, and may be coupled to a pipe within the tank.

Abstract: An industrial hopper and support system includes a hopper having a plurality of receivers complementally configured to receive the top ends of legs of a support. The hopper is particularly designed to receive and discharge both solid and liquid material by the mounting of a selected valve, and the receivers include recesses therein which inhibit the spread of the legs and provide a structural connection between the legs of the support when the hopper is mounted thereon. The hopper may be mounted to the legs without the use of tools, but a separate fastener may be used when it is desired to lift both the hopper and its support from above. The support is provided with openings through primary tubular members which align with crossmembers so that forks inserted into the openings pass longitudinally through the crossmembers.

Abstract: A flexible synthetic resin coupling is provided which is substantially self-sustaining in an initial configuration but provides sufficient resiliency and flexibility to absorb substantial loading, thereby accommodating relative movement between pipes and/or tanks to which it is connected. The coupling includes a conduit having two ends with a coupling positioned at at least one of the ends. The conduit is configured to have a total curvature of at least 270°, and may be configured to have a central axis of the flowpath defined by the passage within the conduit lie in a serpentine configuration in a single plane or alternatively to loop and lie in more than one plane.

Abstract: An industrial tank support includes a platform and multiple supporting legs positioned around the platform with the platform located between the top end and bottom end of the legs. The platform has first and second surfaces thereon which have different configurations, whereby the tank support can be positioned in two different orientations with either the first surface or the second surface uppermost in a tank receiving position to alternatively support tanks having two different bottom configurations. A central opening is provided in the platform whereby a dispensing outlet or other projection from the bottom wall of the supported tank may extend through the central opening. The legs and platform are preferably hollow and in fluidic communication by passages, and the tank support is preferably molded as a unitary member of synthetic resin.

Abstract: A discharge outlet is provided for attachment to a double wall containment tank assembly having an inner tank and an outer containment vessel. The discharge outlet includes a conduit fluidically connected to the fluid receiving chamber of the inner tank and extending exteriorly of the outer containment vessel, a flexible annular sealing member positioned between the inner tank and the outer containment vessel, and couplers for attaching the sealing member to the inner tank and the outer vessel in surrounding relationship to the conduit. The containment area between the two tanks which is designed fro containing spills from the inner tank is thereby fluidically isolated form the access opening through which the conduit passes.
