Abstract: A method and apparatus for storing a material in a container which is exposed to various weather conditions, including rain. The container includes a spreader for distributing the material within the container, as well as a rain shielding member extending from the container for inhibiting the flow of rain along a converging portion of the container. The method includes forming the container having a cover, a sidewall member, a converging portion connected to an outlet portion and a rain shielding member. Thereafter, during a rainfall, the flow of rain is deflected along the cover and the sidewall member away from the converging portion to maintain the converging portion of the container in a substantially dry condition.

Abstract: Apparatus and a related method for facilitating and controlling the flow within, and out of a particulate matter bulk storage facility is provided. The apparatus includes a pre-shaped member, preferably in the form of a substantially impermeable plate, held within the storage facility, in a substantially horizontal orientation, above a discharge port. The pre-shaped member is of a predetermined size and shape and is located at a predetermined height above the discharge port. A vibrator unit is attached to the pre-shaped member and preferably supplied with power transmitted through a flexible conduit which does not restrict the motion of the vibrator/pre-shaped member combination. Operation of the vibrator causes the pre-shaped member to oscillate thereby creating moving voids and shock waves within the stored material which promotes an even velocity profile across the storage facility and produces a mass flow unloading pattern.

Abstract: A method and apparatus for distributing granular material within a container. The apparatus includes a base member for uniformly distributing the granular material within the container by absorbing momentum from the inflow of the granular material. The method includes forming at least two flow paths for the inflow of granular material and then changing the flow of granular material through each of the flow paths to cause a substantially even distribution of granular material within the container.

Abstract: A bulk storage tank is disclosed having an access opening in a lower funnel portion with a removable cover plate. The access opening is located and shaped for permitting a workman to access or partially enter the interior of the tank.
