  • Patent number: 4706962
    Abstract: A dart board in which the various target plates are conveniently assembled onto the dart board target area. The target plates of the board which have the same color are molded at the same time in the form of a grid in which each of the target plates is linked to one or more of the adjacent target plates in order to form an integral grid-like structure. The positions of the various target plates correspond to the positions of the respective scoring areas on the dart board. For a dart board in which the target plates are divided into separate scoring areas on the basis of just two distinct colors, two separate grids are provided, each constituting an integrally supported arrangement of target plates of one of the two distinct colors. The integral grids are designed in such a way that when positioned in an overlapping manner with respect to each other, they define the overall target plates of the dart board with immediately adjacent target plates being of different ones of the two distinct colors.

  • Patent number: 3954625
    Abstract: This disclosure relates to a filter which includes a plastic housing and which has an intermediate filter screen. The peripheral portion of the screen is sealed between the two housing halves by flowing a portion of at least one of the housing halves through the screen and bonding that portion to the other housing half. Further, the housing has peripheral walls which are bonded to one another after partial assembly through an interference fit and a concentrated heating of the material of the housing halves.
