摘要： A polishing media magazine for improved polishing. The polishing media magazine may include a conditioning element for rapid, uniform conditioning and cleaning of the polishing media. The polishing media magazine may include polishing media having sections of raised elevation to contain the fluid and may include a polishing support platen having features adapted to urge the edges of the polishing media upwards. The polishing media may be roll fed from a supply roll across a support platen and onto a take-up roll.

摘要： A finely divided functional solid is readily incorporated into olefin polymers such as polyethylene, polypropylene and polystyrene by blending a concentrate of the functional solid in a carrier of an ethylene/butene-1 copolymer with the olefin polymer. Thus prepared, these blends containing the finely divided solid are ready for fabrication into shaped articles.

摘要： An improved flexible magnetic recording disc assembly comprising an envelope and a flexible recording disc rotatably received in the envelope, the disc having an annular reinforcement member concentrically arranged adjacent the central mounting aperture of the disc. Two embodiments are disclosed: a first having a single annular reinforcement member secured to the spindle side of the flexible disc; and a second having a pair of annular reinforcement members disposed on opposite surfaces of the disc. The reinforcement member has an axial thickness in the range from about 2 to about 7 mils to provide sufficient structural rigidity to resist crinkling and flaring during use; a static and dynamic coefficient of friction not less than about 0.3, and a total electrical resistance measured in the longitudinal axial direction in the range of about 1 ohm to about 50 megohms to facilitate dissipation of static electrical charges which may build up on the recording surfaces of the disc. The reinforcement member is adhered to the flexible disc by means of a cement which is preferably electrically conductive, also to promote static charge dissipation.
