Abstract

Reel-to-reel and cartridge tape drives utilize an air compressor to provide pressurized air to hydrostatic air bearings in the tape path. The air bearings maintain a thin layer of air between the tape and the air bearing surface to reduce friction and wear in the tape path.

Combination Pneumatic Final Filter and Air Speed Control Muffler

      Reel-to-reel and cartridge tape drives utilize an air
compressor to provide pressurized air to hydrostatic air bearings in
the tape path.  The air bearings maintain a thin layer of air between
the tape and the air bearing surface to reduce friction and wear in
the tape path.

      The pneumatic systems for the current and future tape drives
are being configured with final filters and Air Speed Control
Mufflers (ASCMs) as vital components used for cleaning the air and
controlling flow and pressure.  The ASCM replaces the "regulator"
which has been used in the 3480/3490E Tape Drive Systems.  Currently
the only way to mount the ASCM is to come out of the discharge of the
final filter and connect to a section of 3/8ths silicone hose; go
from the hose to a nipple.  The nipple is screwed into a female tee
which has another nipple on its discharge.  The top port of the tee
is a female threaded connection which acts as the mounting point for
the ASCM.  To install the ASCM, as described, necessitates one foot
of hose, two nipples and one tee.  The additional fittings require
extra storage space, more manufacturing assembly time and added cost
to the product for storage, distribution and the control of the
parts.

      To counter the above problem, a combination Final Filter and
ASCM is proposed.  The ASCM is mounted directly to the Final Filter,
thereby eliminating the hose, nipples and tees...
