Active temperature differential control

Image Number 2 for United States Patent #5135048.

An apparatus is provided for maintaining a particular temperature differential and/or adjustable temperature gradient between two, possibly variant domains on a first glass, ceramic or synthetic plate, includes a first active thermal element (heater or cooling element) in contact with that plate for adjusting the temperature of a first domain; a ferrofluid, liquid metal, solder etc. droplet and made of a material that has a thermal conductivity higher than the thermal conductivity of the plate, rests on a second plate and in thermal contact therewith; a second active temperature means (heater or cooling element) on the second plate determines the temperature of the droplet; and the droplet is flattened to different degrees to thereby vary the area of contact between the top part of the droplet and the first plate.
