Abstract: A concrete cutting chain saw has heretofore been considered a rugged performing tool demanding high horsepower and unavailable to the homeowner having only single phase electrical power for powering such a tool. This has been addressed and resolved by a balancing of the torque and chain speed to thereby allow for sufficient torque at the lower horsepower capability of single phase power inputs. Chain width and thereby cutting width may also be reduced, as well as the abrasive elements per cutter may be reduced in order to enable the use of low horsepower power heads.

Alternatively, the figure can be displayed by a screen.

Abstract: An apparatus that moves a jumping element. The apparatus includes a motorized hub that is attached to a housing. The hub can rotate a jumping element, such as a jump rope, about a horizontal axis and/or a vertical axis. The hub is connected to a motor. The jump rope is coupled to the hub by a crank arm. The crank arm automatically releases from the arm in response to a threshold force. The apparatus includes a deactivation element that deactivates the motor when the jumping element is released from the hub. The jump rope can be coupled to the hub by a strap that limits the movement of the rope when decoupled from the hub. Deactivating the motor terminates rotation of the hub to prevent further movement of the crank arm and rope.

This has been addressed and resolved by the reduction of chain speed to thereby increase torque for the lower horsepower capability. Chain width and thereby cutting width is also reduced, and cutting implements per cutter are reduced, all lowering power demands and resulting in a smooth concrete cutting chain saw for homeowner use. Also included is a conversion kit for converting available homeowner power tools, e.g. an angle grinder for use as a concrete cutting chain saw.

Abstract: A toy rocket with an inflatable fuselage that may have a height between 3 to 20 feet. The inflatable fuselage if propelled from a stand by fluid pressure. The fluid pressure is preferably created through both hydraulic and pneumatic pressure to create a relatively high pressure level. The high fluid pressure can lift the relatively large fuselage a considerable distance into the air. Utilizing a fuselage that is inflatable allows for a large fuselage that can be deflated and stored in a marketable package. The liquid/air pressure creates a pressure source that is both safe and sufficient to propel the large fuselage into the air.
