  • Patent number: 7102111
    Abstract: A folds-as-you-eat multi-purpose food-serving apparatus (‘MPFSA’) that is supportable from one end by one hand during eating, and has optional exhibiting means for providing multi-minute close-proximity exposures promoting observer-discernible content and/or user-discernible content, and optionally providing recreational, or display, functionality. The MPFSA is comprised of one or more materials having a pliability which accommodates the bending and unbending of the apparatus a plurality of times in a manner that will not significantly alter the presentation of served food. The MPFSA is also comprised of material(s) having sufficient rigidity to support one or more items of food, having a food-supporting surface which is stiffened by at least one adjacent food-retaining portion which extends upward from an edge thereof, or can be so positioned by a user, to increase the rigidity of, and facilitate the retention of served food on, the apparatus.

  • Patent number: 7004377
    Abstract: A food serving apparatus having a flat food-supporting member consisting of a material sized to prevent served food from contacting unsanitary surfaces, and having sufficient rigidity, to support one or more food items. The food-supporting member has at least one food-retaining portion integrally formed adjacent thereto which extends upward, or can be positioned upward by a user, relative to the food-supporting member, in a manner which increases rigidity of the member. The food-supporting member has at least one bendable cross-section tangent to at least one user-breakable joint of a food-retaining portion to allow separation of the separable joint(s). Breaking of the joint(s) allows a user to bend the food-supporting member downward and away from food supported to facilitate the eating experience. The apparatus accommodates a variety of shapes and optionally includes a fold-over tab to assist a user in securing food beneath the tab and above the food-supporting member.

  • Publication number: 20020088168
    Abstract: This invention is a mixture of low-vapor-pressure hydrocarbon fuels and carbon dioxide mixed at normal pressures and temperatures in a ratio that facilitates the production of micro-droplets that enhance combustion in diesel and similar fuel burning engines resulting in a reduction of particulates ejected and a gain in efficiency. The presence of the gas in the fuel also decreases flammability in the atmosphere above the fuel surface.

  • Publication number: 20020007804
    Abstract: A fuel additive controlling and maintaining apparatus used to eliminate the loss of absorbed CO2 gas mixed into liquid hydrocarbon fuel and particularly diesel fuel. In addition to the gas-enriched fuel, a gastight bag is utilized for holding a stabilizing gas mixture of CO2 and air that is not absorbed in the fuel. This bag, which is located within a protective enclosure and is connected into the ullage of a fuel tank, via a conduit, has approximately the same volume as the fuel tank. A two product refueling means is provided so that gas-enriched fuel is delivered to the fuel tank and the CO2 gas is delivered to the gastight bag. During fuel usage, as the fuel tank ullage increases, the gas mixture from the gastight bag maintains the ullage in a substantially filled condition thus, allowing the fuel to remain gas-enriched.
