Abstract: A company is compared to a generic company model to identify differences between the company and the generic company model. The generic company model includes a work model that describes sequences of tasks that form processes performed within a generic company and a persona model that describes generic personas in the generic company and tasks that each generic persona performs. The differences between the generic company model and the company are used to modify the generic company model to form a company-specific model.

Abstract: Coating with clinging foam the upper interior walls of a generally horizontal pipe. A high-pressure pump delivers jetting water to a nozzle through a normally reeled hose. The nozzle has a body divided by a pressure-actuated valve into two chambers, the first one having a series of high-pressure jet exits. The valve is normally open and, when the high pressure is off, leads into a second chamber having a foam outlet. Two pump and metering devices and a compressor then deliver water, chemical and air mixed into a damp sloppy foam to the hose and thence to the nozzle. A skid supports the nozzle and has a series of skid rods regularly spaced around it. A gravity-operated device at the outlet is connected to the foam outlet from the nozzle's second chamber and causes expulsion of the foam toward the walls of said pipe lying along a predetermined upper sector only.
