Abstract: A model rocket and launch system in which a rocket is launched by combustion produced from a mixture of water and calcium carbide. The water and calcium carbide are combined in a mixing container and launch tube and create a combustible gas. The container and launch tube incorporates a spark chamber consisting of a spark element device and electrode. Both the rocket body tube and launch tube includes a conductive coupling device and is designed to be co-dependent of each other in order to complete an electrical circuit for ignition purposes. The launch tube conductive coupling device and is electrically connected to a spark element device. Electrical current is sent to the spark element device and electrode when the electrical current provided from a high voltage generator passes through both the model rocket unit and the launch system unit via the combined conductive coupling devices.
Abstract: A powered adjustable jaw wrench comprises a wrench body having a handle portion and a head portion defining a stationary jaw, a movable jaw reciprocally mounted to the head portion, a driven mechanism operably connected to the movable jaw, and a drive mechanism mounted to the body member and including a power source and an indexing mechanism. The driven mechanism includes a worm driving the movable jaw and an indexing wheel operably connected to the worm gear. The indexing mechanism is driven by the power source and includes an oscillating pallet member. The pallet member incrementally drives the indexing wheel so as to convert an oscillating movement of the pallet member into an incremental rotatable movement of the indexing wheel.
Abstract: A multi-functional tool comprising an extendable power tool handle unit with an interchangeable connect feature able to receive and power various size interchangeable, adaptable adjustable wrench head units and other adaptable tool attachments. The interchangeable wrench head units are easily connected and disconnected to the power tool handle unit. Each interchangeable adjustable wrench head unit has a self-contained transmission connectible to and powered by the adaptive power handle unit. The interchangeable wrench head units comprise of a moveable jaw, a stationary jaw, and a worm gear. The worm gear is meshed with a rack of the moveable jaw and the worm gear is driven by a motor and transmission. Activation of the motor produces linear reciprocating motion of the adjustable jaw. A power source from the handle provides the power to a control switch. The switch controls the function of the adjustable wrench heads and other powered tool attachments.
