Abstract: Article exchanging grapples are disclosed herein for handling cylindrical objects such as film or tape cartridges, spherical objects or rectangular articles. The fingers of the grapples are shaped so that they substantially conform to a portion of the article being gripped except at the tips of the fingers. The tips are shaped to depart from the surface of the article gripped so as to provide a space for inserting fingers of another grapple. The fetching grapple has the same shaped fingers as the holding grapple. The fingers of the grapples are spring loaded so that when they are not holding an article the normal position of the fingers is slightly less than the cross-sectional width of the article to be held or exchanged. To exchange an article, the fetch grapple moves toward the article held by the hold grapple. The fetch grapple''s fingers contact the article and move along the surface of the article until they interpose themselves between the article and the tips of the fingers of the hold grapple. As the fetch grapple continues to move forward its fingers penetrate between the article and the fingers of the hold grapple spreading the fingers of the hold grapple away from the article. The fetch grapple has now become the hold grapple and can withdraw with the article in its grip.
Abstract translation: 本文公开了用于处理圆柱形物体如薄膜或带盒，球形物体或矩形物品的物品交换抓斗。 抓钩的手指的形状使得它们基本上符合除了手指的尖端之外被夹持的制品的一部分。 这些尖端被成形为从被夹紧物品的表面离开，以便提供用于插入另一个抓钩的手指的空间。 抓取抓斗具有与握持抓斗相同的成形手指。 抓钩的指状物是弹簧加载的，使得当它们不保持物品时，手指的正常位置略小于待保持或更换的物品的横截面宽度。 为了交换文章，抓取抓斗移动到握持抓斗持有的物品。 抓取抓爪的手指接触物品并沿着物品的表面移动，直到它们自身插入在物品和握柄的手指的尖端之间。 当抓取抓斗继续向前移动时，其手指穿过物品和握持抓爪的手指之间，使抓握抓爪的手指远离物品。 抓取抓斗现在已经成为抓住抓地力，可以随着物品的抓住而退出。

Abstract: Two cartridges are shown herein which have the capability of storing a folded endless loop of tape. The cartridges are designed so that by pneumatic pressure the loop of tape may be unloaded from the cartridge by a controlled unfolding and reloaded into the cartridge by a controlled folding. Two cartridges are shown, one containing a porous wall to permit the appropriate air flow to control the folding and unfolding, and the other containing air passages in nonporous walls to control the folding and unfolding.

Abstract: The tape transport described herein utilizes a mandrel about which the tape may be helically wrapped. A rotor carrying a magnetic head is mounted between two halves of the mandrel so that as the head rotates, it sweeps out a track at an acute angle relative to the longitudinal dimension of the tape. Further, the transport has continuous compliant guides before and after the tape helically wraps the mandrel so that lateral disturbances and tension disturbances in the tape caused by the tape supply or the tape sink can be decoupled prior to the tape helically wrapping the mandrel. The entire tape transport, including compliant guides and mandrel, supports the tape with air bearings. The air bearing mandrel may be achieved hydrostatically, hydrodynamically or a combination of both. In addition to the guidance of the tape before and after the mandrel, at very high recording densities it may be desirable to add compliant edge guiding on the mandrel itself.
