Abstract: A modularly tiered clear-trajectory impact commuter apparatus that comminutes rock, drilling materials and other comminutable by impact rather than by grinding or crushing. The invention creates a comminution environment which maximizes the establishment of a clear essentially tangential trajectory for the material between the orbit of each spinning blade and a single rectangular breaker bar. The modular vertical series coupling of the modularly tiered clear-trajectory impact comminuter apparatus may be adjusted to accommodate the material throughput for any environment whereby, for any given size of comminution chamber and rotary blade configuration, any number of tierable, modular comminution chambers may be vertically tiered for achieving the desired material throughput in relation to the load of comminutable material.

Abstract: The present invention relates to a removable utility container or cooler for a canoe. More particularly, the present invention consists of a removable utility container for a canoe which has multiple separate and distinct interior compartments which may be used to store wet or dry goods. Additionally, the present invention has the novel and useful feature of preventing load shifts of the contents of the compartments which would normally result in loss of the canoe contents, taking on water, and ultimately, capsizing. Another benefit is the ability to utilize the present invention as an additional seat for another canoeist.

Abstract: This invention relates to an apparatus for comminuting rock and other material and, in particular, to a rotary driven blade apparatus which comminutes rock, drilling materials and other material by impact rather than by grinding or crushing. More particularly, the invention creates a comminution environment which maximizes the establishment of a clear trajectory for the material between the orbit of each spinning blade and a single breaker bar.

Abstract: A re-inkable ribbon cartridge for impact computer printers featuring duel re-inking rollers of sufficiently small diameter so as to insure rapid rotational speed, ensuring that centrifugal force will cause the ink to migrate to the outer roller surface. A single re-inking port axially positioned over each of the two rollers, permitting rapid, single-point re-inking, when needed.A radially rotational plate on which the blotting rollers are positioned which by spring tension moves so as to keep the ribbon taut.A two-member parallel dam with the surface of each dam component at over-lapping elevations so as to provide two surfaces to act as an unfurling structure.
