Abstract: A seal and method for forming an in-field watertight seal between rigid pipe sections such as concrete pipe sections by applying on the periphery of a pipe section a continuous bead of a non-sagging gel formed from a curable mixture of low viscosity components. A second pipe section is positioned to form a joint with the first pipe section wherein the gap between mating surfaces of the two pipe sections is filled with the mixture which forms a flexible polymeric elastomer seal upon curing. Physical properties of the components and the seal mixture are disclosed.

Abstract: In-field watertight joints for dual wall corrugated plastic pipe sections utilized in drainage and sanitary sewer applications utilize pipe sections having end corrugations without external peripheral corners nearest the pipe ends and a method for forming a self-energizing water tight joint in corrugated plastic pipe.

Abstract: A cart provides facilities for handling and transporting a wide variety of equestrian equipment and supplies, including a saddle, tack containers, bales, packages and buckets, and includes a wheeled frame, a foot pivoted on the frame for retraction to a compact configuration and extension to support some of the items, a rack pivoted on the frame for retraction to a compact configuration and extension to support others of the items, and a shelf pivoted on the frame below the rack for retraction to a compact configuration and extension to support still others of the items.

Abstract: Rheological property measurement employing eccentric rotating disc apparatus wherein measurements of viscous and elastic force data are made at multiple displacements of the disc axes to cancel errors.
