Abstract: ABSTRACT   An hydrogenation process for treating mineral oils, and in particular so-called waste oils, which have been contaminated with chlorobiphenyls, bromobiphenyls, chlorinated naphthalines and terphenyls, or other chloraromatics as well as chloroparaffina or chloronaphthenes for the purpose of the recovery of waste oils which contain chlorine on an industrial scale and in which the mineral base oils that are contained as the main components can be reused.  The contaminated waste oils are subjected to pressure hydrogenation under conditions typical of a liquid phase hydrogenation or a combined liquid/gas phase hydrogenation with hydrogen pressures of 20 to 325 bar, temperatures of 250 to 500°C, and gas-oil ratios of 100 to 3000 Nm3/t.

Title: Tension-restrained articulated platform tower
Inventor: KARSAN DEMIR I
IPC: E02B17/02
Filed: 1988-01-28
Granted: 1991-10-29
Abstract: Abstract A tension-restrained articulated platform tower for offshore oil and gas production.  Two or more tower segments of increasing lateral dimen-sion (proceeding toward the ocean floor) are stacked and articulated by means of a resilient joint.  The platform tower behaves as a fixed tower under normal quiescent conditions with each of the segments above the base segment sitting thereabove in an at rest position.   When  forces sufficient to unseat the compressed resilient joint element are directed against the platform tower (e.g., from wind, waves, or water current), the  tower behaves  complaintly with  tension  elements  secured  to  each corner post providing a restorative force proportional to the amount of tower movement.

Abstract: The invention relates to a method of cutting an interior surface in reinforced concrete.  Holes are drilled to define the shape of the concrete (usually a rectangular block) to be removed, these can be drilled to any suitable depth, which was not possible under prior art methods. Slots are cut between the holes except at one side using an endless wire saw.  An interior cut is made using the endless wire saw from the periphery to the uncut side.  The wire saw is secured in the cutting operations at the interior end of the holes by swivel pulleys secured at the exterior end of the holes to the concrete surface.  The invention also relates to a swivel pulley assembly especially adapted for application in the method.  The invention further relates to a method of cutting a substrate by allowing the wire saw to cut between two pulleys interior of the substrate, from a nonlinear path between the pulleys to a line connecting the pulleys.
