Abstract: A substance dispensing system including a first pressure vessel defining a first interior space; a first substance positioned in the first interior space; a first portion of a first propellant positioned in the first interior space; and a first portion of a second propellant positioned in the first interior space. At least 90 percent by weight of the first propellant is at least one of carbon dioxide, nitrous oxide, and combinations thereof. At least 90 percent by weight of the second propellant is at least one of nitrogen, argon, helium, oxygen, and combinations thereof.

Abstract: An epoxy adhesive that is adapted to enable spray delivery and seamless polymerization during epoxy resin vacuum infusion techniques is disclosed. The epoxy adhesive can include one or more epoxy resins and one or more solvents that are used to dissolve the one or more epoxy resins. An adduct, a tackifier, and fumed silica can also be added to the adhesive.

Abstract: A cannister-based, high solids, low and non-VOC aerosol adhesive and canister based system. The aerosol adhesive typically includes a high solids polymeric base, a hexane or cyclohexane and acetone solvent mixture and a compressed gas dissolved within the solvent. The compressed gas typically includes carbon dioxide, nitrogen, nitrous oxide and air. The aerosol adhesive is adapted to be filled into a cannister including a hose connected to the canister and a spray gun connected to the hose. The system typically includes high solids with a high viscosity. Thus the canister typically maintains high pressures up to 350 psi, but typically at 260 psi while maintaining 325 psi at 130° F., to deliver effective spray patterns.

Abstract: In general, a cannister-based low and non-VOC aerosol adhesive is disclosed. The aerosol adhesive typically includes a high solids polymeric base, a hexane acetone solvent mixture and a compressed gas dissolved within the solvent. The compressed gas typically includes carbon dioxide, nitrogen, nitrous oxide and air. The aerosol adhesive is adapted to be filled into a cannister including a hose connected to the canister and a spray gun connected to the hose.

Abstract: A sprayable adhesive based on nonionic neoprene latex includes in the adhesive mixture a nonionic surfactant, along with the latex, which is a copolymer of chloroprene and methacrylic acid stabilized with polyvinyl alcohol. The adhesive also includes a tackifier, zinc oxide, and an antioxidant. The tackifier is a petroleum-derived hydrocarbon resin, and the antioxidant is a hindered bis-phenol. In order to obtain a rapid drying adhesive, only the latex and surfactant are mixed as liquids. The remaining ingredients are added in solid form and dispersed by mixing under high shear. The adhesive can be applied by spraying from a canister using dimethyl ether as a propellant.

Abstract: A coloring book or the like is provided with image areas that release an appropriate fragrance upon being colored or painted by the user. Microcapsules that contain fragrance oil for a particular fragrance associated with the image area are deposited on the image area of the substrate. Inert walls of materials such as gelatin restrain the fragrance within the microcapsules until activated. A color dispenser such as a felt tip marking pen is adapted to include a reactive agent that when applied to the image area in the normal course of coloring will cause release of the fragrance by rupturing or otherwise interacting with the microcapsules such as by diffusing into the microcapsules and replacing and releasing the oil. The reactive agent may be a solvent such as an alcohol or ketone or a surfactant contained in an aqueous solution mixed with the normal ink or paint of the marking pen.

Abstract: A fragrance sampler for delivering and dispensing perfumes is disclosed. The sampler includes a sheet of synthetic pile fabric or other fabric with similar tactile properties having embedded therein microcapsules containing a fragrance oil. The fabric material, preferably made of a base sheet of polyethylene having segments of polyethylene fiber or strand aligned perpendicular thereto and prepared by means of a flocking process, provides a velvet-like texture that is pleasant to the touch, inviting the user to apply perfume by gently rubbing it on the skin. Microcapsules embedded in the fabric pile are ruptured by such rubbing, releasing a sample of the perfume. The sampler may be sealed by an impermeable film and may be removably connected to advertising material, such as brochures.
