Aerosol generator having heater arranged to vaporize fluid in fluid passage between bonded layers of laminate
InactiveUS20030108342A1Internal combustion piston enginesWater-tube boilersCapillary TubingEngineering
An aerosol generator includes a fluid supply which supplies fluid to a fluid passage and a heater which heats the fluid into a gaseous state, the fluid passage being located between opposed layers of a laminate. The fluid passage can be a capillary sized passage formed by locating a mandrel between opposed layers of the laminate, bonding the layers together and removing the mandrel such that the space previously occupied by the mandrel forms the fluid passage. The opposed layers of the laminate can be copper sheets and ceramic layers can be provided on the outside of the copper layers. The aerosol generator can be used to generate aerosols containing medicated materials.

Power generation methods and systems
A closed loop system for generating mechanical energy at high efficiencies. The system can have a heating source, a superheater, an expander, a receiver, an absorber, a desorber, and regenerator with pumps and controls. The superheater heats a working fluid (a refrigerant or steam). A positive liquid / vapor expander expands a low temperature refrigerant, or steam vapor to the saturated state (having both liquid and vapor parts) utilizing a low-pressure sub-atmospheric exhaust sink. An absorber, generates a low-pressure sub-atmospheric sink using chemosorption which involves the exothermic reaction / absorption of ammonia refrigerant in water. The desorber is used to reconstitute inlet vapor (for reuse) and the regenerator recovers heat generated by chemosorption. The system can meet electrical power needs for residences, businesses or office buildings. The system can supply electrical energy to power grids, and can be an alternative power generation plants.
