Abstract: A flap-type pressure relief valve for venting of pressure out of, for example, an automobile passenger compartment has a flap assembly manufactured by a co-molding operation and inserted into a valve housing to block the flow of air therethrough. The valve flap assembly includes a flap carrier frame formed from a relatively rigid plastic in the first shot of a two-shot co-molding process, and at least one flap formed from a relatively flexible plastic in the second shot. The co-molding joins the flap to a first perimeter wall of the frame along an edge of the flap, and the flap is sufficiently flexible to bend about a line adjacent the edge. In a two flap version, a second flap co-molded into connection with a second perimeter wall of the frame. The resulting flap assembly may be easily connected with the separately-molded valve housing by securing the frame to the housing such that the flaps are positioned over valve seat within the housing. The flaps are co-molded into connection with the frame such that when the frame is secured to the housing to position the flaps over the air passages, the flaps are bent away from their as-molded configurations, thereby generating elastic force urging the flaps toward their valve seats.      The flaps may have rigid plastic stiffeners co-molded into connection therewith. The stiffeners are preferably formed simultaneously with the frame in the first shot of the co-molding process.

Abstract: A collectable card game that represents the unwritten rules of politics, economic and popular culture is disclosed. The game is designed for play by three to six players. The game has a card holder and a deck of playing cards. The card holder is designed to hold four different piles of cards: the Pick Up Pile, the Recycling Bin, the Litigation Fund, and the 501(c)(3) Pile. The deck of cards is composed of three different categories of cards: three-value cards, policy cards, and disaster cards. A three-value card represents a desired good or service the value of which is dependent upon the demographic category chosen by the player at the beginning of the game. A policy card is a card that may be played by a player against an opposing player to slow the opposing player's accumulation of three-value cards. A disaster card is a card that an unlucky player picks from the Pick Up Pile that generally forces a distribution of that player's three-value cards to the other players.
