  • Patent number: 5011134
    Abstract: A waterslide defined by a trough proceeding generally downhill and carrying water to be skimmed over by a rider, is arranged with successive uphill and downhill sections. An elongated drain at a low elevation between the uphill and downhill sections prevents pooling of water tending to slow down the rider. Water is injected into the trough at relatively higher elevations on both the downhill and uphill sections, establishing a gravity flow of water in a forward direction relative to the rider path along the downhill section and in the reverse on the uphill section. The downhill section and the subsequent uphill section are dimensioned such that kinetic energy accumulated by the rider carries the rider over the uphill section and the arc over the uphill section can be parabolic along a free fall trajectory of the rider.

  • Patent number: 4805896
    Abstract: A water ride for swimmers utilizes the linear movement of a large quantity of water of swimming depth at minimal slopes so that the swimmer is moved by the water rather than through it. High volume pumps at low water heads move large quantities of water to create varying water velocity characteristics. A circuitous course is configured generally in the form of an S-curve with a complete 360.degree. circular portion at the bottom with a straight connecting portion from the circle to the top of the S-curve. Water is pumped through the S-curve and connecting portion at a one rate and through the circular portion at another rate. The continuous channel varies along its length in depth, width, slope, and curvature to vary the velocity and flow characteristic of the flowing water. Entrances and exits are provided on the straight connecting portion and on the circular portion. The main entrance on the straight portion is less than 7 feet above the main entrance on the circular portion.

  • Patent number: 4805897
    Abstract: Apparatus for connecting amusement water slides from continuous water flow down the slide to controlled, spaced apart gushes of water enhancing the thrill of the ride and improving the safety thereof. The slide run has a start position at the upper elevated end from a platform and an exit lower end that discharges the rider and water into a landing pool. At least one of the multiple runs is provided with apparatus of the foregoing for having intermittent gushes of water along such run as desired by operator or rider. A vertical tower with stairs and/or elevator provides for movement of the participants from the lower end of the runs to the upper start end of the runs. A water reservoir is provided at some location upstream from the end of the slide run (preferrably at the uppermost end, i.e. the start of the run), and water is pumped from the landing pool into the reservoir which, when full, overflows into the water chute slide.

  • Patent number: 4484739
    Abstract: A slide structure for sleds for human occupancy is disclosed, and is designed to have human occupant sleds sliding down into a body of water. The slide structure has a support framework on which a plastic sheet material is provided and a water supply means supplies only a thin film of water to the upper surface of the plastic sheet material. This conserves power and water, yet the thin film provides a very low coefficient of friction, so that the sleds attain a high speed for a quiet, fast, smooth, and more exciting ride, yet with reduced wear on both the slide and sleds.

  • Patent number: 4304105
    Abstract: A stacked array of inclined flumes interconnected in consecutive zig-zag fashion for cooling canned comestibles upon discharge from a canning cooker. The hot cans are introduced seriatim in a prone or rolling aspect into the upper end of the uppermost flume. Gravity and cooling water combine to transport the parallel, submerged cans down the flumes in transverse register. The rolling action continuously exposes successive portions of the cans to the heat-absorptive water and similarly mixes the cans' contents to effect even cooling. Means is provided for selective removal of heated water from the flumes and reintroduction of cooled water into the flumes at predetermined points to ensure generally uniform water temperature throughout the flumes.
