  • Patent number: 5667718
    Abstract: A traction aggregate suitable for antiskidding applications where reduced dust generation is desired. An expanded substrate is saturated with a liquid absorbed dust suppressant and sealed with a liquid water repellant sealant/dust suppressant. The aggregate traction material may be dispersed over thoroughfares to provide adequate traction for vehicles and, once the snow/ice melts and the roadway dries, leaves behind a non-dusting material that will remain a dust suppressant material during and after subsequent vehicular degradation.

  • Patent number: 5458091
    Abstract: The invention provides a clumpable animal litter mixture having about 5 to 50 weight percent bentonite, about 0.1 to 25 weight percent gum-containing clumping agent and balance filler particulate. The gum-containing clumping agent is formed from a plant selected from the group consisting of the Plantago and Cydonia families. The clumpable animal litter mixture is pourable into a litter box and agglomerates into a clump upon contact with urine. The clump of the agglomerated bentonite, gum-containing clumping agent, filler particulate and urine is capable of removal with a perforated scoop after as little as one minute of formation. The clumpable mixture is formed by introducing the gum-containing clumping agent into a foam. The gum-containing mixture is mixed into the foam to distribute the clumping agent throughout the foam. The mixed gum-containing clumping agent and foam is then added to solid particulate to adhere the gum-containing clumping agent to the solid particulate.

  • Patent number: 5441760
    Abstract: A chipseal overlay coating having in situ deicing properties. An absorbent material such as lightweight aggregate, is mixed with oil, asphalt and/or concrete to form a thoroughfare chipseal overlay. Deicing materials are applied to the overlay or to the absorbent material prior to the mixing process. Due to the highly absorbent nature of the chipseal overlay, the deicing material is absorbed. During icing and snow conditions, the impregnated material reacts with the ice and snow to cause them to melt.

  • Patent number: 5325816
    Abstract: A waterproof receptacle for use in the disposal of animal waste products. The litter receptacle contains a layer of porous expanded shale. The porous shale has a porisity of at least 10% by volume for reducing bulk density of the porous shale and an ability to absorb liquid waste upwardly. Advantageously, the porous structure allows a portion of the liquid to flow to the bottom of the receptacle for subsequent upward absorption. Most advantageously, a screen size of at least +50 mesh (300 microns) is maintained to limit dusting. Optionally, 5 to 25% by weight ammonia absorbing zeolite may be added for odor control.
