Abstract: This Apparatus consists of a collapsible Transport Chair providing the ability to transport a passenger and significant baggage as well as bi-directional operation over rougher surfaces. The Transport Chair includes a strong platform containing a footrest, wheel and braking assemblies. The platform supports a hinged front frame enclosing a passenger seat frame and seat; plus a hinged rear support frame to secure the front frame and seat when assembled. Handgrips and brake levers are provided for the caregiver to push from the rear as well as a fold-down handle bar to allow the transport chair to be propelled from the front. The rear support frame and the front frame along with the folding seat collapse onto the platform for storage and/or transport.

Abstract: The smoke filtration unit described herein has an internal cylindrical duct for ducting exhaust smoke from an exhaust flue to a shutter pivotally mounted within the cylindrical duct. The shutter can move between at least two positions. The shutter, when located in a first position, directs exhaust smoke to a cylindrical filter. An exhaust fan draws the exhaust smoke through the filter. The residual gas is vented to the atmosphere. The cylindrical filter is mounted on a vibration mount that can vibrate the filter to dislodge particulate matter that collects on the surface of the filter. The dislodged particulate matter falls into an ash collection area. The smoke filtration unit is controlled by a microcontroller that monitors temperature and pressure conditions within the unit. If excessive pressure conditions are detected, the microcontroller energizes the vibration mount to dislodge particulate matter from the filter.
