Abstract: A stationary material mixing apparatus located within a cylindrically-shaped conduit. The material mixing apparatus includes a front face, rear face, cone-shaped module having a base and apex supported on said front face and extending toward an upstream end of the conduit. A channel for introducing an additive to the fluid stream is provided, the additive being introduced at the apex of the cone-shaped module, the material mixing apparatus further being provided with three circular openings positioned 120 degrees from each other and each having a baffle configured therein.

Abstract: A simple, wide ranging multi-axial foot with energy return and/or storage. An upper member and a spaced apart lower member are joined through a post connected to the lower member and a ball joint connected to the upper member. One buffer is located anterior to the ball joint-post, one buffer is located posterior to the ball joint-post. A heel member and heel buffer provide additional energy storage and return.

Abstract: A trigger lever (1) is attached pivotally at a fulcrum section (4) to an outside portion of a steering housing (9) that tilts on a troll-motor clamp (11) of a conventional troll-motor assembly. A latch-release line (5) that is pulled from a select position on a steering handle (7) presses a press end (25) of a latch-release rod (23) to release a cross-bar latch (22) from engagement with ratchet slots (20) in quarter-circle edges of juxtaposed ratchet plates (17). This allows tilting of a troll-motor rod (8) to maneuver water obstacles without an operator's having either to stand, bend over or otherwise make inconvenient movements that endanger boat stability, to free both hands or to apply distracting mental effort.
