Abstract: Disclosed are hot melt adhesives comprising at least one first homogeneous linear etylene polymer having a particular density and melt viscosity at 350.degree.F. (177.degree.C.), and an optional wax and tackifier. In particular, disclosed is a hot melt adhesive characterized by: a) at least one homogeneous linear or substantially linear interpolymer of ethylene with at least ibe C.sub.2 --C.sub.20 .alpha.-olefin interpolymer having a density from 0.850 g/cm.sup.3 to 0.895 g/cm.sup.3 ; and b) optionally at least one tackifying resin; and c) optionally at least one wax wherein the hot melt adhesive has a viscosity of less than about 5000 cPs (50 grams/cm.second) at 150.degree.C. Preferred hot melt adhesives for use in adhering cardboard or paperboard are disclosed, as well as the resultant adhered products. Also disclosed is a dual reactor process for the preparation of the inventive hot melt adhesives.

Abstract: Novel colored contact lens and methods for preparation thereof are described. Binding of a color coat to the lenses is accomplished by use of compounds containing the functional groups --CH.sub.2 --O--R.sup.1, wherein R.sup.1 is hydrogen or C.sub.1 to C.sub.16 alkyl, and said --CH.sub.2 --O--R.sup.1 groups are attached to a carbon atom that is part of an aromatic ring, or are attached to a nitrogen or oxygen atom.

Abstract: A razor shaving apparatus is provided having a telescopically extendable and retractable body with a manual handle at one end and a pivoting razor shaving assembly at its opposite end, and having a soap or lotion applicator detachably secured to the razor shaving assembly.

Abstract: This invention consists of a funnel mounted near the wheel well of a vehicle, which contains marble chips and is activated when a button located on the steering wheel is depressed. The flow of marble chips continues until the button is depressed a second time.

Abstract: The disclosed article (e.g. a sanitary napkin) typically comprises (1) an elongated absorbent pad, (2) an outer covering layer in adherent contact with at least one surface of the pad, (3) an adhesive strip or layer on the exposed surface of the outer layer, and (4) a release liner for protecting the adhesive layer. The adhesive layer is useful for removably attaching the article to the inside of an undergarment or the like. Production of the article can be greatly simplified by using a hot-melt pressure sensitive adhesive (PSA) as the adhesive layer. However, the rubbery base for the hot-melt PSA should be very carefully selected. Two types of rubbery polymers provide good results, i.e. (a) an A-B-A block copolymer having polystyrene end blocks and a rubbery poly(ethylene-butylene) midblock and (b) a radial teleblock copolymer with branches having polystyrene terminal blocks and a butadiene segment in the center.

Abstract: A circuit for concurrently producing regulated high-voltage a.c. current and automatically varying d.c. current on one output line, where all adjustment and regulation is accomplished in low-voltage circuits, power supply being particularly useful as the power source for copier and duplicator corotrons. The basic wave shape is a rectangular wave which is amplified and regulated for application as the a.c. input to a corotron. The corotron itself is used as the rectifier for the d.c. bias current, and while the nominal d.c. bias is fixed by adjusting the duty cycle of the rectangular wave to a fixed value, the actual d.c. bias current will vary in accordance with atmospheric conditions and paper thickness, which is desirable for the proper operation of copier and duplicator corotrons. The adjusted duty cycle of the rectangular wave determines the nominal d.c. bias current.
