Abstract: Disposable garments (10) having an elasticized opening including an elastic element (25, 60, 70) joined to a marginal portion of an exterior panel (21, 40, 61, 71) of the garment about the opening along a plurality of spaced bond points (50), and also joined to a marginal portion of an interior panel (20, 62, 72) or folded-over portion of the exterior panel (40a) along the opening, with the outer edges of the elastic element and panel portions joined thereto being substantially coincident. The elastic element is joined to the panel portions in an elongated condition and thereafter allowed to retract to produce micro-buckling (51) of the exterior panel between the bond points.

Abstract: A labial pad (30) having an anatomically conformable configuration with a generally ovate geometry defined by a principal longitudinal axis (L), a minor transverse axis (T) and a generally orthogonal lateral or height axis (H), is comprised of a laterally upwardly directed projection (52) lying generally along the longitudinal axis within the posterior region (54) of the pad and having a prominence (64) proximate the distal end (60) thereof tapering toward the proximal end (58) along the longitudinal axis and to the opposed sides (62) along the transverse axis, wherein the projection is configured for disposition within the vestibule (32) of a wearer over a region bounded generally by the posterior labial commissure (36) and the labia terminating at or about the latter and extending forwardly therefrom over the vulva, to occlude the vestibule against flow of menses or the like while protecting the urogenitals from chafing contact.

Abstract: Tissue comprising a matrix of nonwoven fibers having a basis weight generally in the range of about 25 to 50 gsm. The matrix is a meltblown web having incorporated therein staple fibers. The combination provides highly-improved tissue properties as well as strength and absorbency required for many tissue applications. The tissues may be formed by a conventional meltblowing process involving extrusion of a thermoplastic polymer as a filament in air streams which draw and attenuate the filaments to fine fibers, having an average diameter of up to about 10 microns. The staple fibers may be added to the air stream, and the turbulence produced where the air streams meet results in a uniform integration of the staple fibers into the meltblown web. The matrix may contain from about 30 to about 80 weight percent polymer and have a subjective softness rating of at least about 10.

Abstract: A cellulosic particle, especially useful as a cat litter, is manufactured by agglomerating a fibrous cellulosic feed material in the presence of water, compacting the surface of the agglomerated particles, and drying the particles.

Abstract: Discrete absorbant particles, useful for example as an animal litter, are produced by joining together layers of formed paper pulp, the layers being compressed together in such a way as to remain together under normal use conditions, prior to immersion in water, but so as to wholly or partially separate upon immersion in water, so that the particles are easily flushed down a toilet after use. The product also has uses other than for animal litter, such as in floor sweeping, as a mulch, packing, or otherwise.

Abstract: An adjustable tape head mounting mechanism includes a housing for engaging the tape, and comprises structure for supporting the head housing relative to a head carriage at at least three spaced positions on the housing for head adjustment.

Abstract: A two piece contact lens mold having a pair of blunt, continuous mating surfaces extending around the periphery of the mold cavity is disclosed. Location of the mold parting line tangent to the lens edge substantially eliminates registration problems when a relief groove is provided at the edge of the female member. Parameters for mold materials and important dimensions are also disclosed. The mold can produce finished contact lenses which do not require further machining.

Abstract: A razor cartridge including a blade seat, a seat blade, a cap blade, a cap and a spacer between the blade wherein cutting edges of the blades are exposed for shaving. The spacer is provided with a series of projections, at least some of which extend beyond cutting edges of the blades for diminishing contact between the blades and the skin to reduce potential for scraping and produce improved comfort in shaving. Preferably, various spacer projections of the series extend forwardly differing amounts to compensate for differing skin deformations along the length of the razor blades.

Abstract: Generating lens surfaces to true toric or spherical shapes with lens surfacing machinery employing a dual pivoting system and fixed radius cutter. Lenses are fed across the cutter along a first circular path developing the spherical component of a toric surface while the cutter is simultaneously swept orthogonally across the lens along a second circular path which develops the cylindrical component of the toric surface. Various combinations of spherical and cylindrical curvatures are produced by adjustment of radii of first and second circular paths.

Abstract: An improved cam follower subassembly for use in razor handles which mount pivotable razor blade cartridges. The improved cam follower subassembly includes a cam follower member, a spring and a pusher structured to form an interlocking subassembly to facilitate handling and installation into the razor handle housing during assembly. The cam follower member and the pusher each include a stop surface, the stop surfaces being positioned and oriented such that one is moved into limiting engagement with the other under the biasing action of the spring, which spring may be a compression spring disposed about the cam follower member in a captured manner.

Abstract: Blade sharpening apparatus including two final honing wheels of substantially cylindrical geometrical configuration. The wheels are nominally five inches in length and six inches in diameter, the diameter of the exit end of the wheel being approximately 0.0015 inches greater than the entrance end. The wheel mounted on either side of a continuous blade strip rotate about parallel axes which are also parallel to the edge of the blade strip. A spiral helix is formed on the surface of each wheel such that when the wheels are intermeshed a nip running along and parallel to the blade edge is formed. The material from which the wheels are fabricated is selected to have sufficient resiliency so as to form a final facet on the blade of substantially convex geometry.

Abstract: Generating lens surfaces to true toric shapes with lens surfacing machinery employing a cutting tool having a single cutting edge and provision for universal adjustment of its effective cutting radius.

Abstract: An improved drive for the deflection coil of a cathode ray tube. A first deflection, low-power supply means drives the deflection coil causing the electron beam to scan the face of the tube. A separate second deflection, high-power supply means drives the deflection coil causing retract of the beam. A switch means including a mono-stable multi-vibrator produces an output pulse of selected duration which controls a transistor switch connecting the second supply means to the deflection coil during the retrace cycle. A source of sync signals connected to the multi-vibrator produces the pulse input signals necessary to drive the multi-vibrator thereby controlling the timing of the transistor switch for causing retrace. The use of a separate second high power supply permits rapid retrace, improved power supply matching and minimal heat loss.
