    摘要： An irreversible temperature indicating paint comprises 29wt% to 37wt% cobalt chromite spinel, alumina, gold purple and frit, 35wt% to 45wt% acrylic resin and 20wt% to 30wt% silicone resin excluding solvent. The solvent comprises a mixture of 80% 1-methoxy-2-propanol and 20% dipropylene glycol monomethyl ether. A particular irreversible temperature indicating paint comprises 34.9wt% cobalt chromite spinel, alumina, gold purple and frit, 42.5wt% acrylic resin and 22.6wt% silicone resin excluding solvent. The irreversible temperature indicating paint has four or more colour changes in the temperature range 500°C to 900°C. The irreversible temperature indicating paint is used to determine the temperatures to which various parts of turbine blades, turbine vanes or other component are subjected in operation of a gas turbine engine.

    摘要： A temperature measuring device engageable with a surface of any contour to determine the temperature of each of the several portions of the surface by providing a thermal map of the portions of the surface engaged. The surface engaged by the device may be a portion of a person or a portion of an object or the like. The map is observable and may be photographed if a record thereof is desired. The temperature measuring device has a flexible portion (20) engageable with the surface and conformable to the surface. The portion (20) which engages the surface includes a coating (24) of cholesteric material, such as microencapsulated liquid crystal material which is temperature-sensitive and light-reflecting. The device also includes a transparent fill material (30) therewithin to transmit the thermal image or map therethrough. Thus, a thermal map or image of the surface is provided which is observable and/or recordable through a transparent portion (28) of the device.
