Abstract: A road traffic network wherein the fundamental "building block" is an endless loop of one way traffic flow, a second endless loop of one-way traffic flow completely surrounded by the first endless loop and having traffic flow opposite in direction to the traffic flow direction of the first loop and an interconnecting traffic flow roadway extending between the two loops. The interconnecting roadway merges the traffic seeking to transfer between the two loops such that no vehicle crossovers or intersections are encountered. A road traffic network can be made from a plurality of interconnected "building blocks" or traffic flow systems, each such system being interconnected with either a single two-way roadway or two one-way roadways which, again, allow vehicle transfers between portions of the systems without crossovers or intersections.

Abstract: Disclosed is a beverage infusion device including a percolator within a gas-liquid chamber permeable to air and water containing an infusible, insoluble dry beverage substance such as coffee particles. When the beverage infusion device is repeatedly immersed in and removed from water, water enters into the gas-liquid chamber through the percolator at a point above the coffee particles, drains over and through the coffee particles and out of the gas-liquid chamber. A disposable, miniature percolator for brewing a single cup or limited number of cups of a hot beverage such as coffee is thus provided.

Abstract: A modular system includes a plurality of building units, each having at least one countersunk aperture for alignment with a countersunk aperture of another building unit; and fastening devices for securing the building units together in any of a plurality of configurations to form the modular system, each fastening device including a first bolt for engagement within a first countersunk aperture such that the upper surface of the first bolt is substantially flush with the inner surface of the wall of the building unit containing the respective countersunk aperture, a second bolt for engagement within a second countersunk aperture that is in alignment with the first countersunk aperture such that the upper surface of the second bolt is substantially flush with the inner surface of the wall of the building unit containing the respective countersunk aperture, and a nut positioned within the first and second countersunk apertures for securing the first and second bolts together.

Abstract: A device for holding and displaying a plurality of containers of a cylindrical nature having a circumferential wall, a bottom wall, and an opening opposite the bottom wall provided with a closure. The device comprises three chambers circumferentially spaced about a central vertical axis, each of the chambers comprising a vertically-extending planar support wall, the planar support wall having at least one aperture through which one of the containers may be inserted, and back-up walls associated with the support wall in spaced relation thereto, whereby a container inserted through the aperture is supported by engagement of its circumferential wall of the aperture and by engagement of its bottom wall with the back-up wall.
