Title: Bed system
Inventor: ROSSDEUTSCHER RALPH H
IPC: A47C23/06
Filed: 1997-12-10
Granted: 2002-05-28
Abstract: The bed system has a rectangular frame, with a mattress assembly mounted on the frame. The mattress assembly has upper and lower wooden strip layers and intervening foam blocks. Each wooden strip layer has a plurality of laterally-oriented wooden strips arranged in proximity to each other from top to bottom of the frame, with each strip extending from one side panel to the other side panel. There are three foam blocks, namely two outer foam blocks and one central foam block, running from head to foot of the bed between the wooden strip layers. The side panels have inwardly-facing shoulder portions running the length thereof, and the wooden strips of the lower wooden strip layer rest on the shoulder portions, with the outer foam blocks extending outwardly beyond the wooden strips so as to be in general vertical alignment with the outer walls of the side panels. This permits conventional North American fitted sheets and/or bed skirts to be used if desired. Spaced-apart buttons on the outside of each outer foam block are tied to corresponding buttons on the opposing outer foam block, to prevent the foam blocks from moving laterally outwardly beyond the outerwalls of the side panels. Preferably the bed system includes at least one elevating mechanism to permit the head of the bed and/or lumbar and leg portions to be raised. In double, queen or king sized versions of the invention, a central support member runs longitudinally between the head and foot panels, with support rails on either side thereof. Two of the mattress assemblies are arranged side by side, one on either side of the central support member, the central support member being configured to act the same as a side panel for each of the two mattress assemblies.

Title: Process for the desulphurization of gaseous substrate
Inventor: SCHOUBYE PETER
IPC: C01B17/74
Filed: 1997-12-29
Granted: 2003-04-29
Abstract: A process is provided herein for the desulphurisation of a gaseous substrate containing O2, SO2, SO3, H2, SO4, H2S, CS2, COS and/or organic sulphur-containing components. The process includes the first step of adjusting the water content in the feed gas to provide sufficient water for the production of H2SO4. The feed gas is passed into a first of two serially-arranged catalytic heat exchange reactors. Each of the catalytic heat exchange reactors contains a catalyst unit which is disposed over a heat exchange unit, so that the feed gas absorbs heat from the heat exchange unit and passes into the catalyst unit, where components in the feed gas are catalytically oxidized into SO2, H2O and CO2 at a temperature in the range of 300-500°C, and thereby to provide an oxidized feed gas. The oxidized feed gas is discharged from the first of the two catalytic heat exchange reactors. The oxidized feed gas is then injected into the second catalytic heat exchange reactor. The oxidized feed gas passes through the second of the two catalytic heat exchanger reactors and residual amounts of SO2 are oxidized into SO3 at a range of 300-500°C. This provides a S03-containing feed gas. The SO3-containing feed gas is passed into a heat exchange unit within the second catalytic heat exchange reactor where the SO3-containing feed gas is cooled and water within the feed gas hydrolyses the SO3 into H2SO4, which is condensed and removed from the second catalytic heat exchange reactor. This provides treated gas.      The treated gas from the second catalytic heat exchange reactor is discharged at a temperature that is at least 50°C below the H2SO4 dew point of the process gas after oxidation of the sulphur content in the feed gas. The direction of the flow of the feed gas is cyclically changed, after a period of 1 to 40 minutes, so that a feed gas is injected into a catalytic heat exchange reactor from which the treated gas was discharged in the previous cycle, and first passes through a heat exchange unit in that catalytic heat exchange reactor.
