Abstract: A micro-combined heat and power (mCHP) system includes a liquid cooled variable speed genset that is located to the exterior of a building and that is provides heat and power to the interior of the building. The genset may be configured to output an electrical supply of between approximately between 500W and 40 kW. A coolant loop may extend from the exterior genset to the interior of a building and is configured to reclaim heat from one or more sources of waste heat at the engine, generator, oil and/or exhaust. The reclaimed heat is then transferred, directly or indirectly, to the air flow path of a building heating system. In one embodiment, the reclaimed heat is transferred to a liquid circuit via a liquid-to-liquid heat exchanger and thence to the cold air intake of a forced air furnace via a liquid-to-air heat exchanger. A thermostat may control heat transfer from the mCHP to the heating system.

Abstract: A self-propelled roadway crack routing machine has an operator's station located on a front portion of the machine's chassis and including a forward-facing operator's seat. A driven crack routing cutter drum for routing cracks in a roadway surface is mounted on the front portion of the chassis in a location that can be monitored by a forward-facing operator while controlling machine steering and propulsion. The machine includes a steered rear wheel and unsteered front wheels. Machine steering and propulsion and implement operation may all be effected hydraulically.

Abstract: A self-propelled roadway maintenance machine has an operator's station located on a front portion of the machine's chassis and including a forward-facing operator's seat. A driven implement, such as a crack routing cutter drum for routing cracks in a roadway surface, is mounted on the front portion of the chassis in a location that can be monitored by a forward-facing operator while controlling machine steering and propulsion. The implement may be removably mounted on the chassis by a quick-connect coupling. If the implement comprises a crack routing cutter drum, a plurality of peripherally spaced cutter wheel assemblies may be mounted between disks of the cutter drum, each cutter wheel assembly including a pin and first and second bushings that support the pin on the disks and that are removably inserted into respective bores in the disks. Machine steering and propulsion and implement operation may all be effected hydraulically.
