A portable electric appliance (1, 23) such as a hand held hair dryer uses a brushless electric motor (13, 25) in combination with a secondary fan assembly (14) and / or an air scoop (24) to redirect air toward the motor (13, 25), to maintain a cool operating temperature. The appliance includes a control circuit (50, 80, 94, 102, 110) for controlling the brushless motor (13, 25) and other appliance features. The control circuit and the coil windings (21) of the brushless electric motor are designed to run the appliance at a relatively low current to accommodate a higher operating voltage, thereby operating at a low wattage for reducing extraneous or waste heat. This facilitates placement of the control circuit in a small, portable appliance, and may enhance operation of the appliance in certain modes such as a hair dryer “cool shot.”

Solid metal ammine complexes are applied for safe and high-density storage of ammonia to be released for use as reducing agent in selective catalytic reduction of NOx in exhaust gases. The compositional formula of the metal ammine complexes is M(NH3)nXz, where MZ+ represents one or more metal ions capable of binding ammonia, X represents one or more anions, n is the coordination number (from 2 to 12), and z the valency of the metal ion (and thus the total number of compensating anion charges). Ammonia is released by generating a reduced gas-phase pressure of ammonia inside the container, which is below the equilibrium desorption pressure of ammonia at the operating temperature of the storage material thus enabling the unit to be operated is a safe manner with lower operating temperature and pressure.

A water treatment process whereby heat is used and recaptured to pasteurize water and or sewage effluent. Contaminated waters are partially treatable utilizing bacterial and chemical processes; however some bacteria (e.g. Cryptosporidium and Giardia) are resistant to chemicals. The present process raises the temperature of the water to a desired pasteurization temperature and for a corresponding required length of time to destroy pathogens and viruses. A heat exchanger is employed to use the waste heat from the pasteurization tank to pre-heat the fluid entering the tank. After the initial heating of the tank, the pre-heating reduces the required heat to maintain the temperature of the tank. Make-up heat increases the temperature within a small temperature range. The make-up heat may be waste heat from a separate process.

A mount connects a light emitting device, such as a laser diode assembly, to an optical bench. The mount may include a thermoelectrical module coupled to a sub-element of a heat exchanger extending through an opening formed in the optical bench.

The heat sink enables the laser diode to transmit heat thereto such that substantially all of the heat generated by the laser diode sinks to the heat exchanger. As such, the laser diode transfers virtually no heat to the optical bench so the optical bench is free of deflections or distortions resultant from the heat generated during generation of the laser beam.
