A combined self-cleaning grease and particulate filter and heat exchanger used to collect thermal energy normally vented through flue hoods or other ventilation systems in commercial or institutional kitchens. The system utilizes a piping configuration which circulates fluid in parallel to a plurality of heat exchangers is disclosed. Fluid circulated within the heat exchanger/filter may then be utilized for heating other mediums, such as water or air and to promote drainage of the particulate matter and grease from the filter into a removable storage container.

Combination cook stove heat exchanger, filter, and recirculation assembly

An electroluminescent display is fabricated from an electroluminescent panel having an electroluminescent material coated on a substrate and a transparent conductor covering the electroluminescent material. The transparent conductor is masked according to the desired display format and unmasked areas of the transparent conductor are etched away. The masked areas and, therefore, each resulting region of layered electroluminescent material and transparent conductor, is composed of a unitary display segment and lead segment through which electricity is conducted to the display segment. A metallic conductor is applied to selected areas of the substrate on the surface opposite from the electroluminescent material and each region of metallic conductor is composed of a unitary display segment and lead segment through which electricity is conducted to the display segment.

Electroluminescent display and method of making same

An electroluminescent display is fabricated from an electroluminescent panel having an electroluminescent material coated on a substrate and a transparent conductor covering the electroluminescent material. Conductors, disposed on opposite sides of the electroluminescent material, and leads to the conductors which supply electricity to the conductors to excite the electroluminescent material are coated as unitary members on the electroluminescent panel and an adjacent non-conducting carrier strip attached to an edge of the electroluminescent panel.
