Abstract: An automated system for inflating balloons. A balloon inflator comprises an electronic control system that activates the pressurized gas source to inflate a balloon. The balloons are fed through the inflator on a belt and, at the appropriate time as governed by the electronic control system, pressurized gas is emitted into a balloon. Once the balloon bursts or is removed from the inflator, the belt is advanced and that the next balloon is inflated. In the preferred embodiment, the system comprises multiple inflators and the electronic control system is operated remotely using radio frequency signals.

Abstract: A compact muffler for an internal combustion engine provides significant sound attenuation and back pressure reduction. The muffler is fabricated in the form of an elongated rectangular box with the exhaust pipe connected to an inlet in the center of one end, and the tail pipe of the vehicle connected to an outlet through the opposite end. Several wedge-shaped or V-shaped exhaust pulse splitting plates are located within the casing to split and recombine the stream of exhaust pulses passing through the casing. The splitting devices are located in the casing in positions which cause the different split streams of the exhaust pulses to be intercepted at different distances to cause the pulses passing through different parts of the casing to be out of phase with one another. The out-of-phase streams of the split exhaust pulses are recombined to flow out of the outlet.
