Abstract:
A rigid surface is insulated by a plurality of studs projecting perpendicularly therefrom; a first layer of insulation boards placed against the surface; a plurality of wooden strakes positioned over the abutting insulation boards of the first layer and secured to the studs; a second layer of insulation boards attached to the first layer; and a third layer of insulation boards held in contact with the second layer by means of fasteners secured to the wooden strakes in the first layer.
Abstract:
Apparatus for quickly determining the thermal conductivity of a material over a wide temperature range in a single test. The apparatus comprises a heat sink of metal of known heat capacity, a shell surrounding and spaced away from the metal heat sink providing a space in the shell for placing a sample material, the thermal conductivity of which is to be determined, essentially all around the metal heat sink, means for measuring the temperature of the metal heat sink, and means for measuring the temperature of the shell to thereby determine the temperature difference through the sample.
Abstract:
A ship having a hold containing a tank, for transporting a cryogenic liquefied gas, which is structurally free-standing and is spaced or separated from the ship hold walls, insulation secured to the ship hold walls and hold bottom, a ship hold cover extending over the tank top portion and joined to the ship, and a layer of loose fill insulation and a resilient blanket layer between the tank top portion and the ship hold cover.
