Abstract: A method is provided for forming an endless metal belt assembly with specific parameters to reduce friction, increase lubricity, and transmit maximum torque. An endless metal belt of the invention may be formed by an electroforming process, and is useful as a drive member for a continuously variable transmission.

Abstract: An electroforming process for forming a multilayer endless metal belt includes submerging a mandrel in an electroforming bath, electroforming a first layer on the mandrel, forming a passive coating on the outer surface of the first layer, and depositing at least one additional layer on the oxide coating. By this process, a multilayer metal belt is formed with non-adhesive layers. The belt may then be cut to the desired width, and is particularly useful as a driving member for a continuously-variable transmission.

Abstract: A transport for a rectangular tape cartridge enclosing a supply reel having a web of magnetic tape wound thereabout terminating in a free end attached to a leader block. The illustrated embodiment of the transport is designed to fit within the computer industry standard 51/4-inch form factor and utilizes the 1/2-inch tape cartridge defined in Proposed American National Standard X3B5/85-075. An elongate rectangular housing has internal mechanisms for supporting the tape cartridge therein and referencing the cartridge off its side surfaces. The cartridge is manually inserted into the housing through a slot in a face panel extending across a transverse end of the housing. Electro-mechanical assemblies lock the cartridge in place and complete the loading sequence by engaging a drive chuck with the hub of the supply reel, extracting the leader block from the cartridge, and pulling the leader block to the take-up hub to thread the tape along a tape path.

Abstract: A drive which permits endwise loading of the ANSI standard one-quarter inch tape cartridge in an enclosure having a width of approximately five and three-quarter inches. The drive has a mechanism for partially opening the tape access door of the cartridge upon insertion thereof so that the door pivots clear of a read/write head. Another mechanism is provided for thereafter operatively engaging and disengaging the read/write head with a length of tape in the cartridge.

Abstract: A drive for a tape cartridge having an access door along one side edge thereof. The drive includes a housing having a front panel and an elongate tray dimensioned to have the cartridge inserted endwise thereon. The tray is supported within the housing for longitudinal movement from a retracted position in which the tray is substantially contained within the housing to an extended position in which a portion of the tray extends through a slot in the front panel of the housing. A mechanism is provided for opening the access door of the cartridge while the cartridge is supported on the tray and the tray is being moved from its extended position to its retracted position. Another mechanism is provided for moving a read/write head and a capstan drive within the housing between operative engagement and disengagement with the cartridge after the cartridge has been inserted onto the tray and the tray has been moved to its retracted position.
