Abstract:
A foamed adhesive insulation (10), consisting of a mixture of a foamed adhesive material and a fibrous insulation material, is provided which adheres to a desired surface (12) without the need for a retaining means to hold the mixture in place. While in the flowable state, the foamed fiber insulation can be molded to a desired shape and texture. The foamed fiber insulation adheres and can be applied to substantially any surface, such as wood, metal, masonry, concrete, or urethane, with virtually any orientation. The compression and tensile strengths of the layer of foamed fibers insulation can be selected by adjusting the mixture of foamed adhesive material and insulation particles. The foamed fiber insulation can include additives such as a dye to produce a substantially rigid insulation layer of a desired color, or a fire retardant material to produce a fire retardant insulation layer.

Abstract:
A dispenser (110) for a blown fibrous insulation delivery system which is attached to a fibrous material delivery conduit (114) of the system. The dispenser (110) includes a pipe (112) having a first end (122) which is attachable to the delivery conduit (114) and second end which carries a deflector (120) for compressing a flow of fibrous insulation discharged through the outlet of the pipe (112) and for changing the direction of flow of fibrous insulation compressed thereby. The deflector (120) includes a substantially planar portion disposed at an acute angle with respect to the pipe outlet (126). The dispenser (110) may also include a second deflector for changing the direction of flow of the compressed fibrous insulation.
Abstract:
The present invention solves the problem of controlling the amount of particles of fibres which are emitted in a nozzle from a gas flow when these are transported by the gas flow through a flexible hose or some other canal from a container. Due to the fact that the amount of fibres or other particles which are emitted can be controlled in a simple way, an accurate control of the density of a layer which is applied can be made, an even layer can be achieved and unnecessary material consumption can be avoided. The problem is solved primarily in that a gas flow containing the particles is conducted in a canal to a valve arranged where the particles are to be emitted, a second canal leads from the valve to a suction source and the vent comprises regulating means for controlling the size of the gas flows to the suction source and to the outlet of the valve. By means of this construction a continuous flow of fibres or particles can be guided towards the valve and that part which is not emitted to the nozzle is conveyed further by the suction source and is collected. By means of the above-mentioned method an application of fibres or particles in an adhesive layer, applied with, for example, melt adhesives or cold adhesives, may be guided during a course which can be continuous or intermittent.
Abstract:
Loose fill insulation can be applied to substrates using hot melt adhesive to produce an insulating composition. The fill and adhesive are mixed by use of a spray nozzle (12) and the mixture is applied to the wall using a spray technique. Apparatus (10), including nozzle design, is disclosed for carrying out the process.
Abstract:
A particle sprayer includes a source of discrete particles, a spray outlet coupled to the particle source, and a conduit extending from a pressurized fluid inlet to the spray outlet and configured to constrain a flow of carrier fluid to flow along the conduit toward the spray outlet to propel particles from the particle source away from the spray outlet. The particles including discrete fastening bits having one or more projections, with each projection having an overhanging head for snagging fibers. The particle sprayer may be used to spray fastening bits onto a surface, to turn the surface into a touch fastener.
Abstract:
Provided are a nozzle and a honeycomb filter production apparatus capable of ejecting an aerosol from a plurality of different portions to a base of a honeycomb filter without complicating the configuration of a powder transfer section of the honeycomb filter production apparatus. A nozzle (22) is mounted on an end of an "ejector for ejecting an aerosol" on an ejection side in the honeycomb filter production apparatus. A single introduction port (Ha) is formed at an end surface of the nozzle (22) on one side, and a plurality of discharge ports (Hb) are formed at an end surface of the nozzle (22) on the other side. A single introduction passage (22a) extends linearly from the single introduction port (Ha). A plurality of discharge passages (22b) are each branched from an end portion of the introduction passage (22a) and extend to corresponding one of the discharge ports (Hb) in a direction tilted from the direction of the introduction passage (22a). When a ratio of a sum of opening areas of the plurality of discharge ports (Hb) with respect to an opening area of the single introduction port (Ha) is defined to be "±", and the number of the plurality of discharge ports (Hb) is defined to be "n", 1‰¤±‰¤ˆšn holds.
Abstract:
A system for the application of nanofiber to a substrate includes a tank having an outlet, an agitator disposed in the tank, a pump located at the tank outlet and an applicator disposed proximate to the substrate. One or more fluid conduits extend from the tank to the pump and from the pump to the applicator. The fluid conduits are configured so as to minimize bends and interferences. The system includes a controller. A nanofiber formulation in a fluid carrier in the tank is pumped from the tank to the applicator for application to the substrate at a predetermined flow rate. The pump is controlled by the controller to vary the output of the pump to match the predetermined flow rate, and the nanofiber formulation is applied by the applicator head at a predetermined coat weight on the substrate. A method for the application of nanofiber to a substrate is disclosed.
