Abstract: A dispensing system includes a mobile dispensing device, a fluid transport device, and a fluid supply module. The mobile dispensing device includes a dispensing mechanism carried by a first frame including a first track portion. The fluid transport device includes a second frame supported by at least one wheel for rolling movement of the second frame on the substrate, with the second frame including a second track portion. The fluid supply module includes a base member and at least one reservoir carried by the base member and connectable with the dispensing mechanism for dispensing a fluid stored in the at least one reservoir. The base member includes a third track portion selectively engageable with either one of the first and second track portions for releasable assembly of the fluid supply module with the corresponding one of the mobile dispensing device and the fluid transport device.

Abstract: In a method of repairing a blistered portion of a thermosoftening membrane, a heated air dispensing device is provided, having an elongated nozzle including at least one outlet aperture. The blistered portion of the thermosoftening membrane is pierced to form an opening sized to receive the elongated nozzle. The elongated nozzle is inserted through the opening and into an interior cavity of the blistered portion, with the interior cavity being at least partially defined by a thermosoftening material. The heated air dispensing device is operated to dispense heated air through the at least one outlet aperture into the interior cavity of the blistered portion to at least partially melt the thermosoftening material. A force is applied to an exterior surface of the blistered portion to flatten the blistered portion, thereby substantially eliminating the interior cavity.

Abstract: A shelter assembly has a frame having a plurality of fillable support members, each having a hollow portion for receiving a filling material. The support members are configured to form a structure wherein the support members form walls of the structure. The shelter assembly has a plurality of columns which form corner posts of a structure and a plurality of walls which are removably attached to a pair of adjacent columns. The walls have support members to which at least one panel is attached. The support members are secured to a pair of adjacent columns via fasteners. An upper portion forms a roof of the structure wherein the columns are attached to coupling members of the upper portion.

Abstract: A shelter assembly has a framework having a plurality of structural supports that include fillable support tubes and support sleeves. The fillable support tubes may be filled with fill media and are surrounded by the support sleeve. The structural supports are configured to form a structure wherein the structural supports form the framework of the structure. Various fill media may be used. The structural supports and their associated assemblies are modular and may be configured into a variety of shelter designs.

Abstract: A metering device and method of modular construction allows ease of set up, maintenance and process changes, without the need for changing structures and/or custom parts and without the need for special tools. The metering device monitors various operating parameters with closed loop computer feedback to enhance piston and pump control for accurate metering, to predict when routine maintenance should be performed to avoid failure, to permit automatic fine tuning of displacement during operation and to enhance production within specification tolerances while minimizing downtime. The piston cylinder assembly within the hard tooling can be readily changed to selectively have different diameter cylinders and pistons and to be readily convertible between macro and micro liquid metering. The metering device with its controls and ease of component changes allows metering systems with multiple metering devices to be easily set up with improved synchronization and accurate mixing ratios.
