摘要： A muffler for an internal combustion engine or the like including a casing (21) having an inlet opening (28), an outlet opening (29), a first partition (43) secured in the casing (21) to divide incoming exhaust gases, and a second partition (46) secured in the casing (21) downstream of the first partition (43), which second partition (46) has an opening (39) through which the divided exhaust gases are converged and joined together for exiting the casing (21). The improvement in the muffler assembly which produces both sound attenuation and lower operating back pressure is to provide an intermediate partition (51) secured in the casing between the first and second partitions (43,46) which is formed to permit substantially uninterrupted or unimpeded flow of exhaust gases past the intermediate partition, while a forwardly facing concaved surface (52) reflects sound components in a direction away from the opening (39) in the second partition (46). A method of attenuating sound and reducing back pressure comprising the step of securing an intermediate partition (51) between the first and second partitions (43,46) is provided.

摘要： A lightweight muffler and method for muffling a noise component of a stream of gases is disclosed. The muffler includes a chamber in which gases are directed side-by-side streams flowing in opposite directions. The streams are in contact with each other for the generation of sound dampening eddy currents in the chamber, but such contact does not break down the continuous, low resistance flow of gases through the muffler. The chamber is advantageously formed as an expansion chamber in which gases: enter one end of the chamber as an annular stream concentric with the inlet pipe to the muffler, travel along the inlet pipe to the other end of the chamber, are reversed, and travel as a concentric annular stream of greater diameter in the opposite direction down the length of the chamber for discharge into a passageway leading to the outlet tube of the muffler. A second similarly formed chamber for counterflow of opposed streams and the generation of eddy current therebetween is preferably formed proximate the outlet tube of the muffler.

摘要： A tangle-free tether post assembly for tether animals which includes a post having a lower end adapted to be buried in the ground, and upper end formed to project above the ground. A tether securement assembly is mounted on the upper end of the post at a spaced distance above the ground. The tether securement assembly is positioned vertically above a rotatable sleeve which also is mounted on the post so that the combination of securement assembly and sleeve rotation ensures tangle-free tethering of animals. A ground anchor also is provided on the tether post assembly which may be used to anchor the assembly and remove the same from the ground without digging up the post.
