  • Publication number: 20070181607
    Abstract: A caulking gun includes a cartridge holder, a stock, a plunger, actuator plates, an actuator spring, an adjustable handle, a trigger, a nozzle cutter, a cartridge poker and a retractable arm clip. A handle, able to slide along a lower rail of a cartridge holder, is engaged and disengaged using a trigger. Said handle permits a user to adjust the balance point of the gun at will. To disengage the handle, a trigger is lifted, releasing a forked tab at the rear of the handle that engages the lower rail. Squeezing the trigger reengages the forked tab. The actuator plates are aligned such that a cartridge's internal pressure is relieved each time the trigger is released. A nozzle cutter provides a clean cut, and allows for nozzle tips to be easily discarded. A retractable arm clip is used as a secondary contact point with a user's arm.

  • Patent number: 6767161
    Abstract: A system embedded in a road surface generates power from the passage of motor vehicles. It activates only when vehicles with axles overpass it in the prescribed direction. The power generating device includes a grill and actuating arms, actuating buttons, and a vehicle sensing device for ensuring the system does not activate when motorcycles pass over it. The actuating arms are connected to shafts and gears for transferring vehicular movement into rotational energy to a turbine placed at the side of the road. A speed brake, flywheel and transmission regulate the rotation speed of the generator motor for optimal production of electricity.

The innermost connector is the smaller or smallest and each size is graduated outward therefrom. A secondary funnel is located inside of the innermost female threaded connector to direct fluid into the attached container below the junction of the top of the bottle of container and the first threads. A sealing annular ring or step is located at each connector portion. Single diameter versions are shown as well as slip-on versions for use with threaded, snap-on or straight sided bottle filling openings.
