An improved belt driven tape cartridge including inertial flywheels in intimate contact with the recording tape along the tapes path to reduce high frequency tape flutter, and improved tape-guide members incorporating conically shaped guiding flanges, the guides being positioned adjacent the flywheels to alleviate tape edge damage.

High density belt driven digital data tape cartridge

A waste solvent recovery apparatus to recover tetrahydratfuran (THF) from waste sludge. THF sludge enters the apparatus container through a sludge jet generally pointing in a downward direction. Steam is directed downwardly and at the THF waste sludge jet tending to vaporize the THF while solid contaminants fall to the bottom of the container. The flow rate of steam with respect to waste sludge is adjusted so that the temperature at the bottom of the container exceeds the boiling point of THF and the temperature at the top of the container is less than the boiling point of water.

Waste solvent recovery apparatus

A tape cartridge of the floating roller type, wherein the floating roller is supported in a highly stable manner. The floating roller has axial bearings projecting at its opposite ends, with at least one bearing having a wide flat surface that stabilizes the roller against tipping. The roller bears against tape rolls wound upon reels that have small flanges that aid in starting the tape ends on the reels, and the floating roller has a recess at the level of the flanges to enable the periphery of the roller to move substantially against the tape-supporting surface of the reel. A substantially transparent cartridge housing has slightly raised pads that support the axial bearings on the floating roller, the pads having textured surfaces that avoid noticeable marring by the floating roller bearings.

Floating roller magnetic tape cartridge

A tape cartridge of the floating roller type, wherein a drive belt is utilized which is thin enough and of a material stiff enough in compression, as compared to the tape rolls, that much of the deformation required to produce tape tension occurs by reason of compression of the tape rolls at the point of contact with the floating roller. The drive belt can lie in a groove of the floating roller, so that the floating roller presses directly on the tape rolls.
