Title: Method of Quenching Hot Bulk Material
IPC: C10B39/04
Filed: 1980-05-07
Abstract: Coke is quenched with water, from tank 7, in quenching container 1 and the resulting quenching vapours at about 700 DEG C pass to separator 2 for preliminary dust removal, thence to a waste heat boiler 3 which superheat extraction produces steam which is stored in container 4 for consumer use. Condensation of the vapour and residual dust precipitation occurs in condenser 5. The condensate passes, by way of filter 6, back to the tank 7 for reuse. Permanent gases from the vapour pass to container 10 from which they move through a sulphur purifier 11 whereafter the resultant hydrogen- containing gas is available for chemical processing or heating. The permanent gas may pass to a purifying arrangement 12 without encountering the container 10, and the quenching vapour, as it passes from the quenching container 1, may pass directly to a gas purifying stage 15.   <IMAGE>

Title: Framed window unit
Inventor: LEVERIDGE DEREK WILLIAM
IPC: E06B3/30
Filed: 1981-11-30
Abstract: In a framed window unit, the metal frame 12 which carries the glass G is itself carried by a non- metallic frame 11 secured, in use, to a wall or other surface of a building. The frames 11, 12 are so sized and shaped that, when in position against one another, the back face of the aluminium frame 12 overlaps the front face of the timber frame 11. A soft resilient bead or gasket 13 insulates the glass G from the glass-carrying aluminium frame 12, and that bead or gasket 13 extends over at least the bottom free edge of the back face of the frame 12 to compress resiliently against the front face of the timber frame 11. The timber frame and resilient sealing extension provide an effective internal condensation inhibitor and the sealing bead or gasket can be specially configured to allow any internal condensation to be collected and drained-down through the bottom rail of the aluminium frame 12 and onto an external sill 15. The sealing extension may flex resiliently in an arc curving, from root to tip, away from the central region of the window. The resiliently deformable curving portion may be tubular in cross-section. External air pressure then tend to tighten the seal between the frames. <IMAGE>
