Abstract: A portable dike and floatation device having a lower partition including a water inlet and an upper partition attached to the lower partition. The lower partition is water-fillable via the water inlet. The upper partition includes an air inlet for inflating the upper partition. The lower partition forms a triangular prism having a floor and two sides. The upper partition has two lobes, the lobes cover the two sides, the lobes have a triangular prism shape, and wherein the inner and upper partition forms a square prism shape when the lower partition and the upper partition inflate. At least one support member is positioned within the portable dike and floatation device to provide added rigidity to the portable dike and floatation device.

Abstract: A pipe coupling having an elongated housing comprising a first end and a second end, the housing defining an elongated bore therein with a stop located on an inner diameter of the housing. The stop is located between the first end and the second ends of the housing, and wherein a distance from the stop to one of the first and second ends is greater than a distance from the stop to the other of the first and second end of the housing. A first cylindrical bore extending from the first end to the stop, and a second cylindrical bore extending from the second end to the stop. The second cylindrical bore having a first inner diameter extending from the stop towards the second end of the housing and a second inner diameter extending from the first inner diameter to the second end, and wherein the first inner diameter is greater than the second inner diameter.
