Abstract: A food ricer including a hopper, a first plate having a first pattern of apertures defining a bottom of the hopper, and a second plate having a second pattern of apertures rotatably coupled to the bottom of the hopper. The second plate is preferably rotatable with respect to the first plate. The first and second patterns of apertures being eccentric or non-concentric with respect to each other to allow for the geometric orientation of one pattern of apertures to be quartered, bifurcated, and aligned with respect to the other pattern of apertures for achieving varying degrees of coarseness upon rotation of the second plate with respect to the first plate.

Abstract: A milling device includes a grinding member, a table, a plurality of actuators and a controller. The table has a grinding surface. The table is positioned adjacent to the grinding member such that the grinding surface faces toward at least a portion of the grinding member. The table and the grinding member at least partially define a grinding chamber sized and configured to receive material. Each actuator is connected to the grinding member such that movement of that actuator causes at least a portion of the grinding member to move from a raised position to a lowered position to grind the material. The controller is connected to the actuators and is configured to cause the actuators to move in a sequence that causes the grinding member to wobble as the grinding member is moved by the actuators to grind material.

Abstract: A vibratory crushing apparatus includes at least one trough having an inlet end, an outlet end, and a wall defining a material-receiving space having a first cross-sectional area. The apparatus also includes at least one crusher disposed in the trough, the at least one crusher having an outer surface that conforms to an inner surface of the wall about a circumference of the crusher, and a second cross-sectional area that is smaller than the first cross-sectional area so as to define a gap between the outer surface of the at least one crusher and the inner surface of the wall. Further, the apparatus includes a vibration generator coupled to the at least one trough to cause material to move between the inlet end and the outlet end and to cause the at least one crusher to move relative to the wall of the trough.

Abstract: A bucket for crushing and screening stone and similar materials. The bucket has a scoop-shaped body defining an inlet opening for the stone to be crushed and an outlet opening for the crushed stone, between which a direction of flow of the stone is defined. The bucket further has a stone-crushing mechanism including a first jaw and a second jaw housed in the scoop-shaped body and movable relative to one another. The bucket still further has an element for moving the first jaw relative to the second jaw. The element imparts to the first jaw a combined rotational and translational movement relative to the second jaw in which a first component of the movement is away from and towards the second jaw and a second component of the movement is substantially parallel to the direction of flow.

Abstract: This invention relates to improvements and modifications to a rock crusher. The rock crusher has at least two jaws the jaws being driven at different ends to each other. The non-driven end of at least one jaw is sufficiently free to allow vertical movement of that jaw with respect to the other jaw. This vertical movement imparts a grinding action in addition to the crushing action of the rock crusher. This removes the problems which can occur with wadding and can produce a very fine ground rock.

Abstract: The invention provides a process for removing discharged active zinc-containing material from a mechanically rechargeable zinc battery anode, containing the same, the anode being of the type comprising a skeletal frame, including conductive metal and having a portion of a surface area thereof formed as open spaces, and an active zinc anode component compacted into a rigid static bed of active anode material encompassing the skeletal frame, and having two opposite major surfaces, the process comprising introducing the anode between a pair of spaced-apart first and second crusher plates, each of the crusher plates being provided with a plurality of pointed projections of varying heights and a plurality of recesses of varying depths, the crusher plates being aligned with each other to the effect that tips of projections of the first crusher plate substantially mutually occlude with recesses provided on the second crusher plate and tips of projections of the second crusher plate substantially mutually occlude wit

Abstract: An annular treatment chamber is formed by a gap between inner and outer inertial ("inductively reactive") members. At least one of these members, typically the inner one, is vibratorily driven cycloidally in an orbital path, which is typically circular or elliptical, at a frequency of the order of 50-500 cycles per second. The granular material to be comminuted may constitute material suspended in a liquid or may be in particle form. This material is continually fed into the annular gap and exited therefrom after comminution has been accomplished. While in the annular gap, the material is driven circumferentially around the annular chamber with a high shear force while being subjected to radial vibratory forces developed therein.

Abstract: A mill for crushing or comminuting material such as mineral ores. The mill includes a cradle mounted on fulcrum pins carried by a support frame. An upwardly concave arcuate wall of the cradle carries a relatively large diameter roll member having a hollow interior in which a second smaller diameter hollow roll member is carried. Slots are formed in the first roll member to comminuciate material into and from the interior thereof, and a slot may also be formed in the second roll member to communicate material into and from its interior. The lower portion of the cradle is supported in offset relationship from the fulcrum pins by means of compressions springs mounted on the frame.
