  • Brick additives and methods for using same
    Patent number: 6872677
    Abstract: A brick additive and methods for using the brick additive are disclosed. The additive may include an internal porosity. The internal porosity may display an intra-granular internal porosity in which at least some of the pores are interconnected via an open network of pore spaces. In some embodiments, the additive is capable of maintaining its internal porosity after undergoing thermal modification via calcination, for example. In addition, brick additives of the present invention may display a large surface area.

  • Deck protection system
    Patent number: 6694686
    Abstract: Various embodiments of the present invention provide deck protection systems for use with a deck structure, including planks and support structures. One embodiment provides a body having a deep end, shallow end, a trough section, and opposing side edges. The opposing side edges support the deck protection system between two parallel support structures, and water falling between the planks is captured by the trough and flows from the shallow region to the deep region to an exit located in the deep region. The water passes through the exit and a spout, preventing water from touching the supporting structures and preventing water from falling directly below the deck.

  • Stackable markers
    Patent number: 6688792
    Abstract: A stacked marker is formed by stacking individual stackable markers where each stackable marker is a fully functional marker and each stackable marker can be selected for use and then reassembled to store the restackable marker. Each stackable marker is originally assembled as an otherwise ordinary marker, but with a temporary utility cap, which, upon being inserted into a rear receptacle in another marker, is left therein to form the permanent cap for other markers. When fully assembled, the stacked marker becomes a multi-unit final assembly that affords one the use of a plurality of different types of markers that are snapped together during non-use and taken apart to select individual markers during use.

  • Metallic ink composition for wick type writing instruments
    Patent number: 6561713
    Abstract: An ink composition or system for writing instruments constructed with a polyester fiber reservoir and a porous oriented fiber nib. This ink system will write on both black and white surfaces. On black surfaces, it will reveal itself as being opaque and metallic almost iridescent in appearance. On white surfaces, a tint of color is observed with distinct flecks of silver. The ink system is composted of water as a carrier, a permanent water-based binder, a colored pigmented permanent water-based dispersion of sub-micron particle size, a unique aluminum dispersion of specific particle size in a special carrier, a humectant, a surfactant that lowers surface tension, an anti-settling additive, a preservative and a base acting as a pH adjuster.

  • Systems and methods for extracting liquid from floor coverings
    Patent number: 6355112
    Abstract: An extractor tool for extracting invasive fluid from a floor covering defining a floor surface. The extractor tool comprises a frame assembly, an extraction head, and a drive roller. The frame assembly defines a support surface. The extraction head is mounted to the frame assembly and defines an extraction opening that engages the floor surface. The drive roller assembly is mounted to the frame assembly and also engages the floor surface. A user stands on the support surface between the extraction head and the drive roller assembly such that the user's weight is transferred to the floor surface through the extraction head and the driver roller assembly. The user operates the driver roller assembly to propel the extractor tool along the floor surface.
