Abstract: A set of vertically stackable interacting cartridges for improving the delivery of biocide of a bulk feeder by positioning the stackable cartridges in a stacked condition within a chamber in the bulk feeder wherein the stackable cartridges are maintained in vertical interacting flow alignment with each other to provide enhanced control of the delivery of the biocide carried within each of the stackable cartridges without replacing the control valves of the bulk feeder.

Abstract: Dispensers, principally of water-treatment chemicals, are detailed. The floating dispensers may be inherently unstable in use, rotating approximately ninety degrees (from a generally vertical position to a generally horizontal one) over the useful lifespan of the chemicals initially contained within. Movement of the dispensers to horizontal positions signals users to replace the depleted chemicals. The dispensers also may be stacked into smaller volumes for transit and storage and need not include a separate component for flow adjustment. Rotation of its components additionally may create a “dial-a-dosage” feature of the dispenser, effectively varying depletion rate of the chemicals contained therein.

Abstract: An apparatus for bio-composting domestic waste from residential dwellings, comprised of a tank, a multi-chambered liner and a separator. Domestic waste influent enters one end of a sluice, which has ribs on its surface directing the influent onto the upper section of an inclined sieve. The inclined sieve is angled downward and is permeable. The influent waste flows down the inclined sieve, and free water drops downward through the sieve while separated waste solids slide off the lower edge of the inclined sieve. The multi-chambered liner is set inside the tank under its lid. The multi-chambered liner is partitioned into a first chamber running the length of the liner on one half its wide, which the other half its width is subdivided into a series of smaller sub-chambers running the length of the liner. The chambers are separated by permeable partitions. The walls of the liner are permeable, as well.

Additionally, the axially disposed rotatable shaft, supporting the rotating baskets, is journalled in upper and lower bearings located outside the outer housing member for ease of maintenance. The lower thrust bearing is mounted for direct support by the flooring substrate below the outer housing of the extractor to help minimize bearing contamination and corrosion.

Abstract: A method and apparatus are provided for removing oil from absorbent materials of the type used in components for absorbing oil and containing oil spills. The components are first passed through a press to squeeze some of the oil from the components. The components are then shredded to separate the components into separate pieces of the absorbent materials. An auger pushes the pieces of absorbent materials into an elongated tubular trommel having a perforated sidewall. The pieces of absorbent materials are sprayed with treatment fluids as the trommel is rotated to tumble the absorbent materials within the trommel. The oil and treatment fluids drain from the absorbent materials, and pass through the perforations in the trommel sidewalls and onto a collection trough. The collection trough directs the oil and treatment fluids through a separator to reclaim treatment fluids and oil for later use.

Abstract: Described is a chemical feeder comprising a housing having a base and upwardly extending side walls that define a cavity for containing solid chemical material, e.g., calcium hypochlorite. A hollow coaxial chamber is located within the cavity and is seated on the base. The side walls of the chamber are spaced from the side walls of the housing, thereby to define an annular collection zone. A grid having a plurality of perforations covers the hollow coaxial chamber and has a flange associated with the edge of the grid, the perimeter of the flange being adjacent to, or close to but spaced from, the walls of the housing, thereby to permit liquid communication between the portion of the housing cavity above the grid with the collection zone. An inlet conduit is used to supply dissolving liquid to the hollow chamber. An outlet conduit from the annular collection zone to outside the housing wall removes liquid solution of solid chemical material from the collection zone.

A flange connects the upper end of the housing sidewall to the container sidewall above the grid. A plurality of arrayed openings in the container sidewall above the grid and below the flange level leads to an annular collection zone in the housing. An outlet discharge pipe is connected to the collection zone and an inlet pipe for charging dissolving liquid communicates with the container below the grid.

Abstract: The washer comprises an open-topped vessel having a tube mounted vertically and centrally therein. Post-primary bitumen froth is fed to the upper end of the tube. Pairs of down throw and up throw propellers mounted to rotate in the tube act to shear the froth as it passes down through the tube. At its lower end, the tube is closed off by a transverse wall. Slots are formed in the tube side wall to provide an exit. The sheared mixture thus changes direction as it leaves the tube. In the vessel chamber, solids and water sink downwardly and are removed as tailings through a bottom outlet. The sheared aerated bitumen rises and forms a new forth that is recovered in a launder. Middlings are withdrawn from the chamber and recycled to join the feed. The product froth is reduced in water and solids relative to the feed froth.

Abstract: A shale oil retorting system and novel continuous feed means for retorting oil shale within a retort housing employs a tilted circular conveyor within the housing which allows for continuous feeding of crushed oil shale within the conveyor for subsequent immersion in a hot process oil bath and unloading from the housing. The retort housing is constructed of side body members arranged to provide primary refluxing action of flammable process oil vapors evolved during retorting to prevent explosion. Safety is further augmented by providing an overhead vapor outlet and a sufficient level of process oil in the bath to produce a slight overpressure in the free board region conducive to quickly exhausting shale oil vapor from the housing into an overhead condensing unit. The spent shale particles discharged from the housing are immediately quenched to recover process oil coating the particles and minimize generation of flammable vapors from the hot particles.

Abstract: A method and apparatus for hydraulically macerating and recovering soluble component from a solid material such as waste solid propellant that is semihard. The solid material is fed into a perforated enclosure where it is held until it is macerated such that it can pass through perforations in the enclosure. While held in the enclosure, the solid material is agitated and exposed to jets of liquid solvent under a pressure which is equal to at least about 1000 psig to thereby macerate the solid material and force it through the perforations and to dissolve soluble component such as ammonium perchlorate from solid propellant. In one embodiment, the propellant residue is conveyed to a residue discharge end of the apparatus by a sloping helical conveyor. The helical conveyor provides individual contact stages for counter-current extraction and washing of ammonium perchlorate from the residue with recycled solvent.

Abstract: The apparatus comprises inside a rotating drum, two conveying screws nested inside one another and a partition passing through the drum axis to form two series of succeeding cells inside which the solids and the liquid move in counter-current, two liquid channels being so arranged as to start from each cell to end in another cell, the one channel extending along the drum axis while the other channel lies cross-wise thereto. The cross-wise channel increases the liquid portion separated from the solids by recovering liquid which would otherwise flow back into the solids as portions of the partition pass the horizontal. The channel is obtained by extending one wall of a basket provided in each cell beyond the axis of the drum.
