Abstract: Pressure-sensitive adhesive tape closures for diapers or other garments are formed from backing strips which are divided into three portions of roughly equal area. One end portion and one of the other portions are surfaced with pressure-sensitive adhesive, while the remaining portion is surfaced with a release material; the latter two portions are folded together. In use, the first end portion is adhered to one garment border, a second border juxtaposed or overlapped, the folded portion of the closure then unfolded, and the thus-exposed adhesive surface adhered to the second border. These closures may be formed by cutting parallel strips across an elongate sheet of appropriately configured convolutely wound adhesive-coated sheet material.

Abstract: Sheet materials, such as pressure-sensitive tapes or release liners, are provided with a spectrum of composite coatings having desired release values. The release surfaces, which present both fluorochemical polymer and cured silicone polymer areas, are formed by first applying specific types of fluorochemical polymer and then overcoating with silicone-forming reactants.

Abstract: Normally tacky and pressure-sensitive adhesive tape which displays good adhesion and shear properties, even when contaminated with dust, e.g., talcum powder. The adhesive is a rubbery block copolymer (especially styrene-isoprene-styrene), tackified with a combination of certain liquid and solid tackifiers. The tape is especially useful as a closure for disposable diapers.

Abstract: Particles of molasses absorbed in diatomaceous earth, blended with powdered additives, are dispensed smoothly, without agglomeration or classification according to particle size, by a gravity-fed dispenser having a slowly rotating paddle wheel at the lower front edge of a hopper having a planar front wall and a steeply sloping bottom.

Abstract: A capsule containing fine abrasive grains dispersed in a liquid or low melting solid grinding aid can be substituted for conventional abrasive polishing grains. A novel coated abrasive structure is made by bonding such capsules to a backing sheet.

Abstract: A folding extension table is attached to the discharge end of a table saw to facilitate support of comparatively long workpieces. The extension table is designed to permit miter gauge rods to slide forward without interference. Other features include the manner of attachment, which offers versatility in adapting to a wide variety of saw assembly dimensions and configurations.

Abstract: Solar control film incorporating a "cling" adhesive layer so that it can be repeatedly applied to and removed from a windowpane. The adhesive layer is obtained by coating on the film a solvent-soluble vinyl chloride or vinylidene chloride copolymer containing a vinyl stabilizer, a tack-inhibiting polymeric modifier and a plasticizer for vinyl resins.

Abstract: Normally tacky and pressure-sensitive adhesive tapes, labels, etc. which, when adhered to dry fibrous webs, remain firmly attached when the web and adhesive are thereafter exposed to moist conditions. These performance characteristics, which are not found when conventional pressure-sensitive adhesives are used, result from employing acrylate-based copolymer adhesives made from specific monomers and having inherent viscosities related to the monomers employed.

Abstract: Water-dispellable, optionally pressure-sensitive hot melt resins having superior heat-aging properties are made by reacting (1) diols, of which at least 90% are polycaprolactonediol and/or monoalkylene diols, with (2) dicarboxylic acids, of which up to 95% are aliphatic, 5-25% are aromatic and have a magnesium or alkali metal sulfonate group attached to the ring, and the balance are non-sulfonated aromatic. These resins, which find use as hot melt adhesives for book binding and other purposes, can be readily dissolved or dispersed in a paper beater during a repulping operation. The product can be wound upon itself and supplied in roll form, optionally reinforced by a fibrous membrane.

Abstract: Improved dust collector for radial arm saws of the type in which a generally funnel-shaped flat-bottomed hood, or shroud, is connected to a vacuum hose and positioned at the rear of the worktable. The bottom, or floor, of the shroud has a rearwardly extending slot through which a bolt is inserted to connect the hood to a spacer board of the worktable, thereby permitting the shroud to be rotated so as to align with the saw blade. A support member is positioned between the saw base and the floor to maintain the shroud in level position.

Abstract: Improved form of dust collector for radial arm saws in which a funnel-shaped hood positioned at the rear of the work table is held in place by a clamp mounted so as to overlie the spacer board which is at the rear of the work table. In a preferred embodiment, the clamp has an inverted L-shaped cross-section, a vertical portion of the clamp being gripped between the back of the rear table and the spacer board, and a horizontal portion of the clamp extending over the floor of the hood. Dust and wood particles generated when the saw is used in a ripping position are advantageously and efficiently collected by connecting a vacuum hose to the saw blade guard by a suitable adapter.
