Abstract: A hydrocyclone for separating a combined phase input stream has two nesting truncated, downwardly tapering conical members having an annular space therebetween. A tangential inlet leads to the annular space between the conical members. Alternate embodiments applicable to a hydrocyclone device composed of nesting cylindrical or conical shells forming an annular cyclonic space have passages located on either of the shells to effect an intermediate draw off of a fraction of the flow stream. In addition, a coiled, hollow tube is advantageously situated within the annular space to optimize the flow pattern. Ports may be provided in the hollow tube for removing a gas fraction in counterflow orientation.

Abstract: This invention relates to a flexible, collapsible, floating container (1) for receiving and holding liquids such as oil recovered from oil spills. Specifically, the invention relates to a continuous, sealed, collapsible container having an upper portion which has a positivebuoyancy to maintain an upright position of the container while collapsed and when filled with oil. A rigid ring (2) with a valve (4) for introducing the liquid is located in the upper portion. A stabilizer to prevent rotation and provide stability may be attached to a lower portion of the container. A strengthening layer, such as nylon mesh (16) could be added to surround the container (1), as well as a harness for lifting the container out of the water. The container (1) expands and floats as it becomes filled.

Abstract: A connector assembly is provided for connecting two pipes of dissimilar material. In particular, an assembly is provided for connecting a first end portion of a first pipe to a second end portion of a second pipe formed as a bell housing having a larger inside diameter than an outside diameter of the first end portion and which second end portion overlaps the first end portion. The connector assembly includes a mandrill for attachment to the first end portion, which is formed as a flange extending radially from an outside circumference of the first end portion to face at least a portion of an end face of the bell housing, and an axial tubular extension extending from the flange so as to, upon assembly, reach a point approximately equal to an axial end point of the first pipe, and reside within the second end portion creating an annular space therebetween.
