  • Patent number: 6777377
    Abstract: A composition for sealing porous subterranean formations comprises a mixture of a water-swellable clay and a water insoluble, water absorbent, water-swellable polymer, wherein the mixture is coated with a material that is resistant to penetration by water. The water penetration resistant material helps the delay the onset of swelling of the clay and polymer until it reaches the formations intended for sealing. Mixing the clay with the water-swellable polymer prior to coating assists in coating of the water-swellable polymer with the water penetration resistant material. The coated mixture can be suspended in an aqueous liquid, and then pumped into a subterranean cavity to seal porous formations therein.

  • Patent number: 6719835
    Abstract: A sand casting foundry composition reduces thermal defects that cause veining in metal parts cast from sand casting foundry shapes formed from the foundry composition. A plurality of foundry sand grains are mixed substantially uniformly with a plurality of shale particles, and a curable binder coats the sand grains and the shale particles to establish core and mold foundry shapes used to cast the metal part. Anti-veining capability occurs because the shale particles include mineral components which have an inherent characteristic of crystal structural collapse upon exposure to metallurgical temperatures, and the crystal structural collapse yields space which is consumed by thermal expansion of the sand grains in the foundry composition. This compensatory effect avoids the creation of mechanical forces and stresses within the foundry shape that cause cracks and fissures in the foundry shape that lead to veining.

  • Patent number: 5021094
    Abstract: A grouting composition for sealing a borehole or other cavity contains 90-99.9% finely divided water swellable clay and 0.1-10% polyacrylate thinner having a molecular weight of about 5,000 to 95,000. The grouting composition is mixed with fresh water to provide a completely reswellable, unflocculated, easily placed, low permeability sealing composition. The thinner allows a very high concentration of water-swellable clay in the composition. A preferred grouting composition contains 98-99.9% sodium bentonite and 0.1-2% polyacrylate thinner of molecular weight of about 2,000 to 50,000. In use, 50lb. of the preferred grouting composition is mixed with 11-14 gallons of fresh water, to provide a grouting mixture which includes about 25-40% reswellable solids.

  • Patent number: 4780587
    Abstract: A microwave insert for use in an outer microwave transparent carton for surface heating an object, such as a food product, in a microwave oven. The insert includes a flexible layer of interactive material for converting microwave energy into heat, and a support material, preferably a semi-rigid microwave transparent material such as paperboard, for supporting the interactive material in a position adjacent one portion of the surface of the object in a configuration to minimize the amount of overlaps of interactive material. The overlap is provided along a base panel spaced from the folds which define the base panel and is restricted to a zone wherein the overlap zone is positioned to utilize the maximum possible amount of microwave shielding by the object when the object and the insert are located in operative position within a microwave oven.

  • Patent number: 4626641
    Abstract: A container (2) including a paperboard carton (4) for uniformly heating and crisping the top crust of a large food product such as a pot pie having no side and bottom crusts in a microwave oven including a top panel (9) having crisping means (10) separated by a vertical distance of less than 2.7 centimeters from the top surface of the food product. The crisping means (10) consists of a microwave interactive layer for converting microwave energy received on the inner and outer surfaces of the layer into radiant heat for browning and crisping the top surface of the food product. Crisping means (10) also reflects heat radiated by the top surface of the food product back onto that surface for additional browning and crisping. Uniformity of heating is provided by partially shielding the food product during its exposure to microwave energy, thereby also preventing overheating, loss of mass and changes in texture.
