Abstract: An adhesive dispensing device (10) includes a melt module (12) including a housing (78) that defines a receiving space to receive adhesive and a heater (114) to heat the housing to melt the adhesive, and a control module (14) releasably connected to the melt module. The control module includes a controller (36) to automatically recognize a characteristic associated with the melt module and operate the melt module using instructions stored on the controller that correspond to the characteristic of the melt module. A method of operating the adhesive dispensing device is also disclosed.

Abstract: A dispensing system includes a hot melt unit delivering heated adhesive through a hose to at least one dispenser gun, which is actuated by an outside source of gun actuation. Rather than directly connecting the source of gun actuation to the dispenser gun, the source of gun actuation is connected to the hot melt unit and then to the dispenser gun. For example, the gun actuation signals may be terminated at a terminal block in the hot melt unit, which enables the hot melt unit to monitor the gun actuation signals. The dispensing system is operable to perform various diagnostics pertaining to the dispenser gun and the system as a whole based on these monitored gun actuation signals.

Abstract: A locomotive diesel engine test assembly generates a once-per-cycle signal phased to the top dead center of a predetermined piston in its cylinder. A locomotive diesel engine crankcase door is hermetically attached to the crankcase so as to cover a camshaft located therein. An outer tube extends through and is hermetically and fixedly attached to the crankcase door, and an inner tube extends through and is hermetically and pivotably attached to the outer tube. A proximity sensor is attached to the inner tube and positioned near and generally perpendicular to the camshaft. A marker is attached to the circumference of the camshaft and is detectable by the proximity sensor once per revolution of the camshaft.
