A small, high performance magnetic tape transport system for use in recording and reproducing data is adapted to receive a cartridge in which a single supply reel for the magnetic tape medium and the magnetic tape are carried. The cartridge is capable of being easily loaded into the transport system for recording (writing) and reproducing (reading), and is also easily ejected from the system for storage or replacement. A driving mechanism for the reel in the cartridge and a permanent take-up reel or hub are carried by the transport. The separate cartridge driving mechanism and take-up hub are each driven by their own separate motor system. In the embodiment disclosed, means are taught for loading the cartridge into the transport system, positioning and seating the cartridge in contact with the driving mechanism in the transport system, and for ejecting the cartridge from the transport system. The cartridge ejecting mechanism is designed so that it does not exert any force or pressure on the cartridge during loading, recording or reproducing operations.

Cartridge loading and ejecting mechanism for use in a tape transport

A magnetic tape cartridge is disclosed, which cartridge includes a single rotatably mounted reel. The reel is mounted within the cartridge in a manner which prevents it from rotating until the cartridge is loaded into a tape transport device. Additionally, the reel is mounted within the cartridge so that it is substantially self-centering when loaded into a tape transport device. The cartridge includes a door which is normally closed, but which is automatically opened when the cartridge is inserted into the tape transport device. When the door of the cartridge is opened it provides access to the tape in the cartridge.

Tape cartridge

A tensioning mechanism for the fluid conductor hoses of a feed mounted rock drill comprises a plurality of fluid cylinders mounted stationary on a bracket supported midway along the length of the drill feed channel. Elongated tubular pistons are slidably supported in the cylinders and are connected to the respective hoses. The cylinders may be charged with pressure fluid such as grease or the like to bias the pistons to tension the hoses and prevent damage to the hoses or interference with movement of the drill.
