Abstract: A modular system for monitoring a hydrogen-cooled generator includes a skid having a platform and an upwardly extending support. The support is attachable to a hydrogen gas purity monitoring module, a generator overheat monitoring module, a hydrogen gas dryer module, a gas/generator monitoring module, and a gas manifold. The gas/generator monitoring module allows monitoring the operation of the hydrogen-cooled generator and generating data regarding the performance of the hydrogen-cooled generator. The gas/generator monitoring module may display an optimization factor or data regarding the performance of the hydrogen-cooled generator, and/or may be connected via a communications link to a remote control center.

Abstract: Multi-purpose apparatus having a single power-driven disc-like element to effect chipping of branches and related debris fed into a disc-mounted blade/aperture configuration on one side of the disc with a vacuum/volume reduction structure having fan blades disposed on the other side of the disc cooperating with a cylindrical screen. The disc and screen are located within a housing having an air inlet for air moved by the fan blades whereby debris can be drawn in from the front end of an air passageway connected to the air inlet and discharged with the chips and debris through the screen out of a single outlet. The outlet is located at the top of a generally volute housing and the apparatus can be mounted on wheels for walk-behind operation with handlebars supporting a debris collection bag attached to the outlet end of the housing. A passageway conducts air into the housing to which attachments can be affixed.
