Abstract: A refrigerated product storage system incorporates first, second and third vertically spaced storage sections carried by a unitary support frame attached to an inner wall portion of a fresh food compartment door of a refrigerator. In the most preferred form of the invention, the storage system includes an uppermost dairy compartment, an intermediate chill compartment, and a lower, slidable drawer. The chill compartment is provided with a door which is pivotably mounted about a vertical, inboard pivot axis, with the door being formed with a cut-out handle portion adapted to be aligned with a passageway formed in a partition separating freezer and fresh food compartments of the refrigerator. With this construction, a supply of low temperature air is directed from the freezer compartment directly into the chill compartment through the cut-out handle portion. The door of the chill compartment is provided with a latching mechanism, preferably an over-center acting latching mechanism.

Abstract: A refrigerator door is provided with a dairy compartment defined, at least in part, by a first dairy compartment member and a second dairy compartment member. The first dairy compartment member is movably connected to an inner wall portion of the door and the second dairy compartment member is slidably attached to the first dairy compartment member. In accordance with a first embodiment of the invention, the first dairy compartment member is constituted by a dairy compartment cover that is pivotally connected to a pair of spaced dike portions formed integral with a liner of the door. In a second embodiment, the first dairy compartment member constitutes a dairy compartment defining shelf member or bucket that is selectively, removably attached to the dike portions. In each of the first and second embodiments, the second dairy compartment member constitutes an element which is slidably attached to the first dairy compartment member and divides the dairy compartment into varying volume storage zones.

Abstract: A retainer assembly for preventing tall food containers placed on a shelf of a refrigerator door liner from falling off the shelf when the refrigerator door is abruptly opened or closed includes a retainer member in the form of an elongated rod or bar that includes an intermediate portion and bent end sections and a retainer element. Each of the bent end sections includes an out-turned terminal end that is pivotally connected to the dike portion of the inner liner. The retainer element preferably comprises a block that defines various spaced grooves or recesses. The retainer element is attached to a sidewall of the dike portion with the various grooves being spaced vertically.

Abstract: A rack supportable on a refrigerator shelf for storing a bottle of wine, a carton of eggs or a plurality of cylindrical beverage cans. The rack includes a vertical sidewall terminating in an inwardly directed top flange for engaging the refrigerator shelf, a longitudinal depression in a bottom wall for supporting the wine bottle and an incline in the bottom wall for permitting the beverage cans to automatically self-feed towards the front of the rack.

Abstract: A method for extending fractures in underground formations obtained by controlled pulse fracturing through the use of stabilized hydrogen peroxide solution. Controlled pulse fracturing causes radial fracturing near the wellbore. In order to extend these radial fractures further into the formation or reservoir, stabilized hydrogen peroxide is forced into the radial fractures. Stabilizing agents in the hydrogen peroxide react with metals in the formation causing the hydrogen peroxide to breakdown and form gas pressure sufficient to extend the radial fractures. Hydrocarbonaceous fluids are then obtained from the formation via the extended fractures which contact natural fractures in the wellbore.

Abstract: The present invention relates to the in situ recovery of mineral values, particularly uranium, from subterranean formations that contain sulfur in organic or inorganic forms where the sulfur causes premature deletion of an oxidant and reduction in permeability of the formation. The adverse effects due to the presence of the sulfur in the formation are substantially reduced in accordance with the present invention by treating the formations with an aqueous solution of iron-complexing agent and then oxident to preferentially oxidize and solubilize at least a portion of the sulfur in the formation. The present process may be applied either as a pre-treatment process to be followed by a leaching process or simultaneously with the leaching process.

Abstract: Method and apparatus for mixing a gaseous oxidant (e.g., oxygen) and a lixiviant (e.g., an aqueous carbonate solution) at a downhole location before the oxygen-saturated lixiviant is injected into a formation to be leached. The invention involves establishing a mixing zone in the well by positioning a mixing means, comprising a housing, in the well at the downhole location. Lixiviant is flowed down the well and through a restrictive opening in the housing to substantially increase the flow velocity of the lixiviant. At the same time, gaseous oxidant is fed to the housing and is trapped therein by the increased velocity of the lixiviant and by packing material in said housing. The lixiviant flows through the trapped oxidant which, in turn, dissolves into the lixiviant to saturate same. Additional packing material is provided in the housing to remove undissolved oxidant from the saturated lixiviant before it is injected into a formation to be leached.
