and kitted in less then 24 hr to accommodate their trip through Phoenix. "Aluminum structural framing met our performance criteria (loads are less than 1 ton) while letting us assemble the tether-pull machine quickly and easily," says Shelef. The extruded aluminum and bolttogether connections were also

Installation involves pressing the fastener into place in a properly sized drilled or punched hole. This displaces sheet material, causing

of extra-long extruded seals. Let's look at these issues one at a time. CROSS SECTIONS. Inflatable seals come in a wide variety of shapes or cross sections. But engineers can meet most design needs with one of six basic designs. All seals can expand in whatever direction is needed. The main issues regarding
