Abstract: The present invention features a vessel for isolating a target in a sample. The vessel includes at least one reaction chamber, a wash system and an effluent system. The reaction chamber includes a closed cell adapted to receive a support, a sample potentially containing target and at least one first probe, and thereafter being closed. The probe is capable of associating with the support and the target to form a support-probe-target complex and sample debris upon imposition of probe binding conditions within the reaction chamber. A wash system is capable of introducing solutions into the reaction chamber for washing the support to solubilize and suspend sample debris. Upon imposition of wash conditions, solutions are allowed to enter the reaction chamber to solubilize such sample debris. An Effluent system is in communication with the reaction chamber and capable of receiving sample debris and wash solutions.

Abstract: An electrical outlet floor box including an upright, open top cylindrical housing member, a ball ring, and a cover assembly secured to the open top of the housing member by means of the ball ring; said housing member is embedded in a concrete floor and the upper portion removed in proximity to, and in a plane parallel to, the surface of the concrete. The ball ring insures that the upper surface of the cover assembly is parallel to the surface of the concrete floor even if the axis of the cylindrical housing member deviates somewhat from normality to the surface of the concrete floor.

Abstract: A process and jig for field bending relatively large diameter plastic pipe, the jig being to guide the pipe at the point of tangency adjacent the bend after the pipe is heated and bent to form a smooth curvature to the desired radius and degree of bend as determined by the jig. The jig includes a two-piece spreader tube and a right and left hand guide, each adjustable in width, angle and spacing. The guides are U-shape and extend beneath the spreader tube so that the pipe may be placed on a flat horizontal surface. Each guide is provided with a protractor, one of which includes an offset scale so that offsets or curves with generally parallel tangents may be formed. The spreader tube includes a scale to ascertain the chord in terms of the radius for given degrees of bend.

Abstract: Multiple duct underground conduit and method of installing the same which involves plastic tubing and male and female coupling plates which can be field assembled at the trench site to form sections which are then connected to each other in the trench without requiring someone in the trench. One form of the invention uses a wedge lock while the other employs a hook and latch, both forms simply requiring lowering of one section adjacent the other. Concrete may then be poured about the conduit in the trench and the trench covered.
