    摘要: A drop-out fire vent for a building has a plastic dome that softens and loses structural integrity with increasing temperature. However, the dome is prevented from dropping out by an internal trap door controlled by a fusible link that will release at a precise temperature. This allows the vent to be used in combination with sprinkler systems such as ESFR systems that require opening of the vent at a precise temperature after the sprinklers have been triggered.

    摘要: A shutter used, for example, as a sunshade has blades that are pivotally coupled to frame members of the shutter by respective pivot shafts that are split longitudinally into upper and lower halves. The pivot shaft halves can be adjusted radially with respect to one another to take up free movement that might otherwise allow the blades to vibrate when the shutter is in use.
