A dispensing applicator for solids and semi-solids is provided that includes a flexible strap and internal guide to actuate a movable holding container within an openable housing, that includes tactile and audible position detent signals to prevent the strap and the solid or semi-solid from inadvertent and accidental movement, and to signal that the supply of solid or semi-solid is nearly exhausted. The openable housing has an opening at one end and a longitudinal slot. The flexible strap is con...

A solids separator including: an elongate tubular housing rotatable around a central axis; a fluid inlet at one end of said housing adapted to receive a flow of a fluid including entrained solids; a first and a second outlet at the opposing end of said housing, wherein, said rotatable housing is effective in imparting a radially outward force to the entrained solids flowing through the separator whereby the solids are concentrated at the peripheral portion of the cross-section of the flow at the...

Apparatus for separating various sizes of solid minerals, e.g., mixtures of fine sediment and larger particles or aggregates of ore, has rotating drum with internal lifters and external grousers and enables tumbling of solids in stream of water flowing through drum.

There is disclosed a process and an apparatus for comminuting solids wherein an attrition-grinding mill includes a grinding chamber having an inlet means enabling a feed slurry of a particulate solid to be comminuted to be introduced into the grinding chamber and an outlet means including a sieve for allowing therethrough a ground product slurry whilst retaining a granular grinding medium within the grinding chamber, the sieve being disposed below the surface of the contents of the grinding cham...

An article of manufacture comprising (i) a double cone having apexes at opposite ends, said double cone having independent gas inlet means at about the apex of the first cone and multiple independent gas outlet means in the second cone, and (ii) a hollow tube, open at both ends, inside the double cone running from one apex to the other apex having independent gas inlet means at the apex of the first cone and independent gas outlet means at the apex of the second cone.

A solids charger of the type having a main support frame with a solids supply chute thereabove feeding solids to a vertically and angularly adjustable, with respect to the horizontal, reciprocable charger plate positioned under the solids supply chute for receiving solids toward its rear end and feeding the granular solid materials to a reactor from its front end. The improvement in such a solids charger of a reciprocable charger plate reciprocably mounted in fixed angular relation to a charger ...

A solids removal device for use in the treatment of water and wastewater includes a final settling zone for removal of lightweight particles. The final settling zone comprises a liquid-carrying conduit defining a path for the upward flow of liquid and encloses settling plates dividing the conduit into flow spaces of upwardly increasing cross-sectional area and providing impingement and conglomeration surfaces for the accumulation and downward flow of solids.

A solids separation system is provided, designed for pneumatic separation of pieces of scrap particularly metallic scrap, into light and heavy fractions. The mixture of pieces of scrap is fed into an enclosed separation vessel wherein they fall by gravity into a horizontally directed stream of air blown into and across the separator vessel, whereby the heaviest pieces fall through the air stream into a heavy solids hopper and the lighter materials are carried downstream by the force of the horiz...

An inclined rotary kiln for direct-contact heat exchange between a coarse and a fine granular material. The coarse material travels downward through the kiln. The fine material is introduced near the lower end of the kiln and is transferred up the kiln stagewise via helical ducts in the kiln's wall. Inlets to the ducts have grates which reject the coarse material but accept the fine material. The ducts extend helically upwardly relative the kiln and rearwardly relative kiln rotation so that the ...

This invention is to a process and system for controlling solids distribution in a gas-solids reactor. Solids distribution is controlled by controlling electrical charges between solid particles flowing between conductive surfaces within a gas-solids reactor. The electrical charges are controlled by conventional means such as by grounding the opposing conductive surfaces, or by applying a voltage to one of the opposing conductive surfaces.
