Abstract: A water slide tube adapted for braking during hydroplaning in a catch or landing pool of a water slide. The water slide tube includes a tube body and a tube speed control assembly, which has a floor attached to a bottom surface of the tube body. The assembly includes one or more drag-inducing elements, provided in or on the floor, configured to produce drag when an outer surface of the floor travels over an upper surface of the catch or landing pool. The floor includes a sheet of flexible material joined along its peripheral edge to the tube body. The sheet of the floor includes a planar portion arranged to be tangential to the bottom surface of the tube body. The one or more drag-inducing elements may include at least one hole extending through the floor providing a passageway for water to an interior space of the tube body.

Abstract: A railroad ballast removal system capable of removing ballast material from below a rail line. The railroad ballast removal system includes at least one rotary cutting wheel having a plurality of individually replaceable cutting attachments positioned about a perimeter of the rotary cutting wheel. Each rotary cutting wheel is attached to an articulated arm capable of adjusting the position of the rotary cutting wheel along varying axis. The articulated arm is mounted to a support structure capable of transporting the rotary cutting wheel to a portion of railway requiring maintenance of the ballast material. The railroad ballast removal system is able to operate at a spot location or in a continuous manner down a length of railroad track. The ability to manipulate the rotary cutting wheel along the various axis allows the rotary cutting wheel to be used for ballast removal in locations wherein adjacent railways limit cutting access.
