Abstract: A composition for cellulostic fibers containing amino silicone to impart improved hand feel. The composition may be included in a lotion applied to tissue paper and may include a hydrophilic softener. A carrier for trace substances, fragrances, vitamin E, aloes and coloring agents may also be used. Such carrier may comprise microcapsules.

Abstract: The invention comprises a method to increase the water absorption of tissue paper towel products by incorporating super-absorbent polymers (SAP) in between the laminated tissue plies. The SAP is dosed in selected places in the tissue towel manufacturing process without the need to substantially change the current converting or manufacturing process, or the major equipment that is used or the properties of the base sheet tissue paper.

Abstract: An internal, self-locking hub assembly for a compact, audio, tape cassette is described, including a locking member with at least one movable portion and a spring. The cassette includes at least one receptacle formed in the raised annular rings thereof. The spring normally forces the movable portion radially inward in a direction parallel to the plane of the hub, wherein the movable portion engages the at least one receptacle in the raised annular ring, and locks the hub against rotation. On the other hand, when the tape cassette is placed into a tape player/recorder, the spindle thereof enters the center of the hub, abuts and moves the at least one movable portion radially outward against the force of the spring, thereby unlocking the at least one movable portion from the at least one receptacle and permitting normal rotation of the hub.

Abstract: A tape cassette for use with an external tape player/recorder apparatus having upper and lower cassette halves and an independent tape guide for insertion between the cassette halves. The independent tape guide is a subassembly comprising an elongated bridge molded of plastic and having a top planar surface, a bottom planar surface, a front, a back, a left end and a right end, two pairs of corner posts located substantially centrally of the front and a plurality of lateral projections extending from the front in relatively perpendicular relation to the planes of the top and bottom of the bridge. Each pair of corner posts has holes formed therein to receive a stainless steel pin therethrough also in perpendicular relation to the planes of the top and bottom of the bridge, which together with the plurality of lateral projections define the tape sliding surface.
