Abstract: A computerized method for monetizing a commodity, product or service in exchange for an insurance product, and valuing assets of an entity in exchange for collateral for surety is disclosed. A request is received by an insurer from an entity for an insurance product. The insurer uses a computer to calculate a cash premium required by the insurer for the insurance product, to calculate an economic output needed to fulfill the cash premium, to calculate a cash premium threshold, and an economic output threshold. The computer instructs via a display, a printout, or a transmission, if the cash premium is greater than the cash premium threshold and if the economic output is greater than the economic output threshold. A computer-readable medium records the terms and data of an agreement for a delivery of economic output by the entity in exchange for an insurance policy provided by the insurer.

Abstract: A side pocket mandrel having an internal deflector to prevent a latch seated therein from being bent out into the open bore. Receptacle bore sub-assemblies and deflectors welded into slots cut in the mandrel body such that the interior faces of the welds can be coated with protective material.

Abstract: A valve comprising a valve body (10) having inlet (14) and outlet (18) passages communicating with a valve chamber (15). A valve element (90) is movable through the valve chamber adjacent a valve seat (92) and a flow deflector ring (104) having a central opening which has discontinuous deflector surfaces (106) around a central opening separated by spaced grooves (108) arranger to disrupt flow a stream of fluid flowing between the valve element and the valve seat to prevent the formation of a vena contracta downstream from the valve seat. A plurality of sleeves (34,36) having cylindrical walls divide the valve chamber to form an entrance section (15a) and an outlet section 15b).

Abstract: A side pocket mandrel is of hollow metal tubing having a cross-section that is symmetrical about an axis and in which one of the symmetrical cross-section halves reveals a smoothly continuous convex curve, comprises a first, second and third circular arc portions of different radii and different centers of gyration; the first having a radius r.sub.1, the second r.sub.2, and the third a transcending radius r.sub.3 with r.sub. 1 greater than r.sub.2 and with r.sub.3 being less than three times the sum of the radii r.sub.1, r.sub.2 and the distance between the centers of the first and second portions, but no less than one-half of such sum of r.sub.1, r.sub.2 and that distance between the centers.
