  • Patent number: 8469831
    Abstract: This invention relates to gravity-driven car racing, specifically an improved ramp, such as used in the popular Pinewood Derby race, which is cycloid shaped. The present invention eliminates excessive centripetal force and related problems such as car oscillation caused by prior art ramps which are curved too much or curved in the wrong places. The present invention comprises a ramp shaped as a section of a cycloid curve with the ramp bottom tangent to the horizontal coasting run. It can be shown mathematically that such a curve will produce the least possible centripetal force and associated friction increase in the car wheels as it accelerates toward the coasting run. The present invention causes a ramp to assume the cycloid shape by applying appropriate bending forces to the underside of the ramp. In a preferred embodiment, a hinged brace automatically applies the key bending force as the main support legs are lowered.

  • Publication number: 20030203759
    Abstract: Mechanized structures for the launch of cars in installations for amusement parks such as, for instance, roller coasters or similar attractions. This is a mechanical system so as to launch cars by exploiting the energy stored by a counterweight pivoting around an axis. The counterweight is integral with a beam which carries, on the other end, a pushing device which, when it has to give the push, leans against the rear of any car of the train and pushes it along a semicircular track of launch and then it leaves said car. During pushing phase the counterweight loses the stored energy and slows down till it stops while the cars accelerate towards the predetermined track. To allow the counterweight to store again potential energy, an electromechanical transmission with low power is sufficient; said transmission, in much longer time, brings back the counterweight to the highest point ready for a new launch at high acceleration which, differently, would need a much higher power.

Because the riding surface of the present invention is contained along its outer periphery, the water ride can be compact so that is suitable for placement in a relatively small area of land. The ride surface itself has an inclined surface, a transition turn area, and a downward declining surface which feeds back into the pool. This butterfly configuration is relatively compact, and can be situated such that the flow of water comes from and returns to the pool area. In one embodiment, the invention also has a unique nozzle outlet area which is at or slightly below the elevation of the water surface in the pool, so that riders may skim over the nozzle area and onto the riding surface directly from the pool area.

  • Patent number: 5688180
    Abstract: A molded, two-surface, reversible slide, includes first and second elongated sliding surfaces. Each of the sliding surfaces has a bottom portion defining a generally, concave cross-sectional shape, and is elongated in a direction transverse to the concave cross-section. Each surface has a pair of side walls extending from its respective bottom portion. The reversible configuration is effected by first and second sliding surfaces which are in a back-to-back relation with one another. The side walls of the first surface are formed contiguous with a respective one of the side walls of the second sliding surface, defining first and second outer walls. The slide may be used as part of a slide system which includes a slide support structure and one or more slides.

  • Patent number: 5540622
    Abstract: The present invention provides a water slide which includes a device for reducing the impact felt by riders or users when they contact the slower-moving water at the bottom of an incline. Such slower moving water can be particularly injurious to a user who is traveling at relatively high speed (e.g., down a particularly long or steep slope). The device for reducing impact is a section of slide of predetermined length which includes air injection nozzles for reducing the apparent density and viscosity and increasing compressibility of the water to enable the user to slow down more gradually by transitioning from reduced density water to normal density water.

  • Patent number: 5328851
    Abstract: A system for detecting trace concentrations of an analyte in air includes a preconcentrator for the analyte and an analyte detector. The preconcentrator includes an elongated tubular container comprising a wettable material. The wettable material is continuously wetted with an analyte-sorbing liquid which flows from one part of the container to a lower end. Sampled air flows through the container in contact with the wetted material with a swirling motion which results in efficient transfer of analyte vapors or aerosol particles to the sorbing liquid and preconcentration of traces of analyte in the liquid. The preconcentrated traces of analyte may be either detected within the container or removed therefrom for injection into a separate detection means or for subsequent analysis.

  • Patent number: 5165690
    Abstract: An automatic ball return for practicing golf putting includes a ramp that receives the putted ball, converts the energy of the rolling ball into vertical movement up the ramp, and then through gravity, rolls the ball back down the ramp towards the user. Two legs attached to the ramp are interlocked when the device is in use to provide the proper contour to the ramp, and disengage so the legs and ramp lie flat when the device is to be stored or transported. The ramp includes a target on each end, and the device may be positioned with either leg along the ground allowing either target to be used.

  • Patent number: 5137497
    Abstract: For the most part, there has been very little innovation in the design of water or other slides. An interesting development in this area involves a slide apparatus including a trough with an upper slide surface of generally parabolic, upwardly opening cross section throughout its length, the slide being tilted from the rear inlet end thereof to the front outlet or discharge end thereof. Riders on the slide move along a path of travel resembling that of an underdamped oscillator, and for the first time riders are able to experience the sensation of sliding forwardly and backwardly within a waterslide configuration, in complete safety, throughout the duration of the ride.
