  • Patent number: 5088262
    Abstract: An anchor system including a C-track and a two-pronged anchor capable of installing and holding sheet insulation material on a support surface in a compressed state is described. The method of installation utilizing the anchor system of the present invention provides for both the attachment of the insulation to the support surface and compression of the insulation during a single installation operation. The method involves forming a plurality of folds with the sheet insulation to a desired height followed by the insertion of one prong of the two-pronged anchor through the folds to compress the folds and hold the folds in position. The second prong of the anchor initially serves to aid in the compression of the folds and secondarily serves to connect the compressed insulation to a next layer of folds formed and stacked on top of the already formed folds. The use of a separate attachment means with each fold of the insulation material is not required.

  • Patent number: 4829734
    Abstract: A ceramic fiber insulation module is now provided from ceramic fiber units of finite length. The formation of the module can be initiated by folding an individual ceramic fiber strip or blanket, which is in unfolded condition, in a manner doubling the ends over on themselves. Then the double-over ends are folded up towards each other. As a result, the module, in cutaway, may be described as a "B-fold". The module presents an unbroken blanket surface for the hotface. The module also lends itself to fastening by cross-tying, between adjacent modules, to a backing member. Cross-tying can provide joint compression at the through joints which occur between modules.

  • Patent number: 4640202
    Abstract: A lightweight cover provides heat insulation for a heated vessel such as a soaking pit. The cover can be readily assembled in a manner providing for ease of repair plus simplicity of maintenance. The cover has a pair of opposing frame members with ceramic fiber insulation positioned therebetween. The insulation is secured in movable engagement such as a free-floating and swinging engagement. In this mode, compression can be exerted against the insulation to most desirably reduce heat loss otherwise caused by heat induced ceramic fiber shrinkage. Moreover, with this structure a ceramic fiber heat seal can be achieved around edges of the soaking pit.

  • Patent number: 4606473
    Abstract: A lightweight cover provides heat insulation for a heated metal container, e.g., a ladle. The insulation cover is assembled in a manner providing for ease of repair plus simplicity of maintenance. The assembly has a frame member with depending guide means useful for straddling engagement with the container. Frame member impact assemblies provide resilient mounting of the cover on the container. Ceramic fiber insulation is placed within the frame and abuts upwardly against a roof over the insulation. The insulation is secured to the roof. Stiffeners above the roof connect with the frame member. The entire insulation cover assembly is most particularly useful for retarding radiant and conductive heat loss from the container.

The cover can be readily assembled in a manner providing for ease of repair plus simplicity of maintenance. The cover has a pair of opposing frame members with ceramic fiber insulation positioned therebetween. The insulation is secured in movable engagement such as a draped and swinging engagement. In this mode, compression can be exerted against the insulation to most desirably reduce heat loss otherwise caused by heat induced ceramic fiber shrinkage. Moreover, with this structure a ceramic fiber heat seal can be achieved around edges of the soaking pit.
