Abstract: A floor game including tiles which are laid on a playing surface forming a playing area, and an optical instrument. Each tile is covered by a polarized film. A path across the playing area is revealable by utilizing the optical instrument available to a game facilitator. The players see a design on the playing area. A path across the playing area is invisible to players not wearing the optical instrument. Each player traverses the path with assistance of the game facilitator and by observing steps taken by the previous players. The object of the game is for players to discover and traverse the path across the playing area from end to end through a team effort. In an alternative embodiment, the game is played with one or more teams utilizing one or more playing areas with each team trying to complete a path on their respective playing area.

Abstract: A drainage assembly is disclosed for draining water from the vicinity of a subterranean construction surface, such as a subgrade foundation wall. The assembly comprises a hollow drainage panel formed by a sheet-like base and a filter media, the filter media being spaced apart from the base by a plurality of members that project from the inner surface of the base. The base has at least one hinge, and preferably two closely spaced parallel hinges, extending along its entire length between adjacent side edges, thereby allowing the panel to be easily folded and set into place against a foundation, with the portion above the hinge resting against the vertical foundation wall and the portion below the hinge resting atop the foundtion's horizontal footing. The apparatus further comprises a connector assembly that connects the panel to a standard drain pipe to convey water away from the foundation.

Abstract: Processes for tufting substrate or primary carpet backing using conventional double needle bars but in which the needles may be shifted less than a full gauge. Processes of the present invention may employ a conventional double needle bar tufting machine to which is added means for shifting or indexing the hook bar laterally to the machine direction of the substrate being tufted. Timing of shifting of the hook bar may be coordinated with timing of shifting of the needle bar and advance of the substrate through the machine to allow piles to be tufted into the substrate at any desired lateral position with respect to previously tufted piles. The invention creates additional pile color pattern alternatives and eliminates repetitive patterns otherwise necessitated by full gauge shifting. Elimination of repeat color sequences reduces matching color sequences on adjoining edges of adjacent carpet tiles made from such substrate which otherwise accentuate or highlight the seams between carpet tiles.

Abstract: A suspension clamp for suspending and clamping an elongate flexible member, the clamp having: (i) a saddle in which the elongate flexible member may sit, ii) a mounting to support the saddle with respect to a fixture, (iii) a closure latch to restrain the elongate flexible member in the saddle, and (iv) a resilient member mounted to the closure latch and having a bottom face adapted to clamp an elongate flexible member positioned within the saddle when the closure latch is closed.

Abstract: A sampling system controller includes a control unit for interfacing with a collection chamber module having a plurality of sampling chambers. The control unit controls the times at which the sampling chambers acquire samples of a fluid flow and control flow rates into the sampling chambers. The timing of the sampling chambers and the flow rates may be programmed by a user and downloaded into the control unit through an interface. The control unit measures the flow rate of the fluid flow to be sampled and controls the flow rate through each sampling chambers in order to achieve a desired and known rate through the sampling chambers. The flow rates through the fluid flow and through the sampling chambers are recorded on a data module. The control unit may be equipped with a portable weather station for monitoring weather conditions and with a global positioning system for determining a geographic position of the sampling chambers. The weather and location information may be recorded on the data module.
