Accumulators Deliver New Payoffs
cycle time of 16 sec — 8 sec to cycle a 4-in. bore, 12.5-in. long cylinder with a 1-in. rod; and 8 sec of dwell time. The operator wants higher productivity, but the dwell segment cannot change because workers need time to load and unload the machine. However, adding an accumulator increases machine

Superstrong nuts and bolts
reinforced with long-carbon fibers, Icotec's lightweight nuts and bolts sport ultrahigh specific strengths of up to 2.4 million psi/lb/in.3 This contrasts to aluminum and titanium with specific strengths of about 0.2 million and 1.2 million psi/lb/ in.3, respectively. The composite's semicrystalline

Polyester
are mixtures of polyester resins, thermoplastic polymers, and glass-fiber reinforcement. These are used to mold parts with smooth surfaces that can be painted without the need for prior sanding. Bulk-molding compounds (BMC) are mixtures of polyester resin, short-glass fibers (1/8 to '/, in. long

Acrylic
transmittance of 92%, exceptionally low haze level of approximately 1%, and an index of refraction of 1.49 -- high enough for use in lenses and other optical applications. Colorants produce a full spectrum of transparent, translucent, or opaque colors. Most colors can be formulated for long-term outdoor
