A blowhead (10; 100) for blowing air through a neck opening (12; 112) of a glass parison (14; 114) to cause it to expand. The blowhead defines an air supply passage (28; 128) through which air can enter the parison and an exhaust passage (45; 145) through which air can exhaust from the parison. The cross-sectional area, transversely to the direction of air flow, of at least a portion of the exhaust passage is adjustable.

An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
