Abstract: A glass sheet is provided with a coating which will automatically reflect infrared radiation if the ambient temperature is above about 45.degree. F.-60.degree. F. and will transmit infrared radiation if it is below about 45.degree. F.-60.degree. F. Such a coating is placed on the exterior surface of the glass. Additionally, the interior of the glass may be provided with a controllable infrared transmittable or reflective layer of material which is activated by means of an electric current transmitted therethrough and which will reflect infrared energy if so energized, but otherwise will transmit such infrared energy. This layer of material is preferably placed on the interior of the glass surface and activated during the nighttime period so that infrared energy is not transmitted outwardly. Alternatively, the controllable infrared transmittable or reflective layer of material may be positioned both on the exterior and interior of the glass surface.

Abstract: A method of preparation of fiberglass filaments for subsequent coating with metal wherein the fiberglass filaments first are immersed in a wetter solution containing alcohol, a detergent, and an ethylene oxide and propylene oxide copolymer surfactant. Following this treatment the filaments may be treated with conventional palladium chloride or tin chloride activators, followed by treatment with an acid accelerator and then autocatalytically coated with metals such as copper, gold, palladium, cobalt, nickel, and nickel alloys of phosphorus, boron, or tungsten. A second electroplating or immersion plating step may be included where the metal-coated filaments are electroplated or immersion plated with either the same metal, or a different metal taken from the group consisting of nickel, silver, zinc, cadmium, platinum, iron, cobalt, chromium, tin, lead, rhodium, ruthenium, or iridium.

Abstract: In order for diabetics to test themselves for stat glucose levels to determine whether or not they should self administer insulin, it is necessary to draw a drop of blood from the diabetic's finger, place the drop of blood on a commercially available blood glucose test media and compare the resulting color of the test strip with a standard chart to determine the blood glucose concentration. This invention is directed to a cheap, disposable, combination sterile pad support and lancet which may be used to disinfect the end of the finger area and then used to stick the finger to draw blood and the sterile pad may also be held on the stick site firmly, thus aiding the blood clotting time after the drop of blood has been placed on the blood glucose test strip.
