摘要： A cover for a video record has a generally unbroken rectangular perimeter. A record player has permanent magnets that cooperate with paramagnetic inserts in the record cover to open the cover for loading and unloading a recording disk. The player has a clamp mechanism that enters the opened cover to clamp the disk for these operations.

摘要： A cable strain relief device comprises a cable manifold having a pair of generally planar surfaces upon opposite sides thereof formed with a plurality of cable receiving channels extending generally lengthwise along the surfaces. The channels are spaced from one another transversely of the length of the manifold and are formed so as to undulate transversely in a serpentine manner to provide strain relief for cables such as fiber optic cables placed in the channels. The channels are sufficiently deep to permit the placement of two cables in each channel.
