An improved hose is used to install loose fill insulation. The hose includes projections extending from an inner surface which serve to condition the insulation as it proceeds through the hose and is dispensed. In a first embodiment of the present invention, the projections are formed so as to be perpendicular to a longitudinal axis of the hose. In a second embodiment of the present invention, the projections are formed so as to be angled, by an angle less then ninety (90) degrees with respect to the longitudinal axis of the hose. In a third embodiment of the present invention, the projections are formed with a serrated edge. In a fourth embodiment of the present invention, the projections are formed as part of a cap member which is disposed around the periphery of the hose.

Hose used to install loose fill insulation

A device for determining density of a material flowing in a conveying system includes a duct segment in fluid communication with the conveying system. The duct segment is coupled to the conveying system by isolation fittings, which allow the weight of the duct segment to be measured independent of the weight of adjacent portions of the conveying system. Further, a method for determining density of a material flowing in a conveying system includes weighing a duct segment having material free fluid flowing therein. The duct segment having a mixture of material and fluid flowing therein is also weighed. The difference of the two weights is used to determine a linear density of the material.

An improved hose is used to install loose fill insulation. The hose includes projections extending from an inner surface which serve to condition the insulation as it proceeds through the hose and is dispensed. In a first exemplary embodiment of the present invention, the projections are formed so as to be perpendicular to a longitudinal axis of the hose. In a second exemplary embodiment of the present invention, the projections are formed so as to be angled, by an angle less then ninety (90) degrees with respect to the longitudinal axis of the hose. In a third exemplary embodiment of the present invention, the projections are formed with a serrated edge. In a fourth exemplary embodiment of the present invention, the projections are formed as part of a cap member which is disposed around the periphery of the hose. In a fifth exemplary embodiment of the present invention, the projections include an additional perpendicular projection member extending therefrom.

To hose used to install loose fill insulation

A dispenser for a blown fibrous insulation delivery system which is attached to a fibrous material delivery conduit of the system. The dispenser includes a pipe having a first end which is attachable to the delivery conduit and second end which carries a deflector for compressing a flow of fibrous insulation discharged through the outlet of the pipe and for changing the direction of flow of fibrous insulation compressed thereby. The deflector includes a substantially planar portion disposed at an acute angle with respect to the pipe outlet. The dispenser may also include a second deflector for changing the direction of flow of the compressed fibrous insulation.
