Abstract: A system and method for measuring volumes and areas using electromagnetic induction techniques. A current is generated and fed into one of two coil assemblies to induce voltage into another coil assembly to provide accurate values for volume or area.

Abstract: A muzzle loader apparatus for use with pistols, which have a curved handle and are loaded with lead balls. The apparatus has a handle engagement portion to house the handle of the pistol, this portion generally conforming to the shape of the handle. A support portion is fixedly connected to the handle portion and extends beyond the length of a barrel, so that a swivel arm can be mounted on the free end of the extended support portion. The swivel arm can move from a horizontal inoperative to a vertical operative position. A ramrod projector is swivelly mounted onto the swivel arm and can move to an alignment position with a bore of the pistol, when the swivel arm is in a position perpendicular to a longitudinal axis of the barrel of the pistol and the support portion. The swivel projector has a loading arm insertable into the pistol bore when the swivel arm is in the vertical operative position.
