Abstract: A method and system for automatically feeding animals uses identifiers on the animals and controls access to one or more food sources to control the amount consumed by each animal. The system is controlled by a programmable processor and can provide or prevent access and cut off access once provided based on the particular animal seeking food.

Abstract: A method for attaching a fused-quartz mirror to a conductive metal substrate which comprises the steps of tinning one surface of a fused-quartz mirror with a solder of substantially pure indium, tinning a metallic substrate with an indium eutectic alloy consisting essentially of indium, bismuth, lead and tin having a melting point substantially below that of indium, heating the eutectic alloy to a temperature substantially above its melting point, but below that of the solder, floating the mirror into place, and subsequently cooling the alloy to a temperature substantially below its melting point.
