Abstract: In general, sound resonators or mufflers are bulky self-contained metal bodies, which are expensive to produce and to install in an engine intake or exhaust system. A relatively simple substitute, which can be tailor made to attenuate sound at various frequencies include two arcuate casing sections which are interconnected along one side edge by a hinge, so that the sections can be wrapped around an engine air intake tube, a latch on the other side edges of the sections for securing the sections together to form a sleeve around and coaxial with the tube, an inlet nozzle on the interior of each section for extending into the tube, and partitions extending between the inner and outer surfaces of each section for defining elongated, tortuous, sound attenuating passages.

Abstract: In the production of foamed plastic articles using a screw extruder, it is known to introduce a gaseous foaming agent into the plastic while the latter is passing through the extruder. It has been found that a foamed thermoplastic with pores or cells of uniform size and distribution can be produced by passing a gaseous foaming agent, e.g. nitrogen gas through a central passage extending substantially the entire length of the extruder screw, discharging the agent into the thermoplastic proximate the discharge end of the extruder, and mixing the foaming agent with the plastic immediately prior to discharge of the mixture into a mold.
