Abstract: A portable and collapsible isolator is taught for containing radioactive, chemical or biological agents. The isolator is comprised of a collapsible frame, movable between a collapsed transport position and an open operational position, and a flexible and collapsible envelope in the form of an airtight bag attached to the frame to define a cavity. The envelope remains airtight in both the collapsed and open positions. One or more sealable openings are formed in the envelope for insertion and removal of the radioactive, chemical and biological agents into and out of the cavity. The isolator may optionally include at least one glove extending from one or more of said sealable openings into the cavity, for handling said radioactive, chemical and biological agents inside the cavity.

Abstract: A method for forming odd-shaped mufflers is achieved by first introducing an unfilled muffler insert having a desired number of pipes and partitions within a two-piece shaped tool. Fibrous material is introduced within desired compartments formed between the shaped tool and unfilled insert to form a filled insert. The shaped tool and filled insert are then placed on a winding device. A yarn thread is then wound and secured around the fibrous material within a gap created between the two pieces of the shaped tool. The winding device and shaped tool are then removed from the filled and wound muffler insert. The wound and filled muffler insert may then either be pressed into a previously formed muffler shell, or alternatively, the muffler shell may be formed around the wound and filled muffler insert to form the muffler.
