This device is the pivotally mounted front covering for a scoop adapted to pivot to an open position when loading and unloading and to a closed position when holding and transporting material.
A member closely adjacent to the cylindrical platen* of a typewriter that serves to guide a record-medium* into close contact with the platen. It is usually a thin sheet of relatively rigid material having a length dimension approximating the length of the platen and is arcuately shaped to approximately the radius of the platen whereby it conforms to part of the periphery of the platen. It is usually located underneath the platen and closely adjacent thereto so that the record-medium is guided between the apron and the platen to be partially wrapped around the platen. The apron may also serve as a mounting for feed-rollers* that cooperate with the platen to move the record-medium in a line-space* direction.
A defined area on an airport or heliport intended to accommodate aircraft for purposes of loading or unloading passengers or cargo, refueling, parking, or maintenance. With regard to seaplanes, a ramp is used for access to the apron from the water.
Apron has been defined 10 different ways in documents like USPC Consolidated Glossary, USPC Consolidated Glossary, Glossary of Coastal Terminology, and 7 more.
