A manual spray cleaner for removing dirt and stains from fabrics and carpets comprising a spray bottle having two separate chambers and a single dispensing spray outlet for dispensing controlled amounts of liquids from each of the chambers. Continuous isobaric catalytic combustion followed by isothermal expansion and the use of separate compressor and expander devices are used. The fluorescent material is mixed with another fluorescent material emitting green, yellowish green, or yellow light, and the mixed phosphor is combined with a semiconductor light emitting element for emitting bluish purple or blue light, to fabricate a white light emitting diode which efficiently emits a warm white light with a high efficiency. In one embodiment, the compliant backing member comprises a semi-rigid backing member cut into a spiral shape to provide compliancy. The user can thus select the nature of the foodstuffs which are to be cooked.
