Latest Patents

One of McCollum's notable patents is titled "Tape excursion control means using tapered-wall vacuum column." This invention describes an apparatus that improves the operation of magnetic tape decks featuring both parallel and tapered wall vacuum columns. The design aims to minimize tape excursion in the tapered columns. Rapid acceleration of the tape can cause airflow reversal from the vacuum columns, potentially acting as an air pump and leading to issues like flutter and oscillation. McCollum's solution includes a check valve between the tapered vacuum column and the vacuum plenum, which closes during outward tape excursions to maintain increased vacuum force, preventing unwanted movements.

Another significant invention is "Tape reel positioning and latching means." This device is designed to position, latch, and remove reels from a driving hub in magnetic recording devices. The mechanism includes an elastic sleeve that secures the reel and employs an actuation rod that interacts with link bars and shoes, allowing for precise control over the reel's position. This innovation is versatile, enabling operation either through a manual handle or a vacuum actuator.
