Patent DE-19806276-A1 (DE)
Title: Catalytic recovery of sulfur from hydrogen sulfide
Inventor: KUNKEL JOSEF
IPC: C01B17/04
Filed: 1998-02-16
Abstract: Sulfur is recovered from a gas stream containing hydrogen sulfide and oxygen, which passes downwards through layers of catalytic material that are initially warmed and later cooled to release liquid sulfur. The invention is concerned with the catalytic section of a Claus process for sulfur recovery. Gas, passing downward through the reaction column (8) is warmed in zone (9) to reaction temperature, and then passed through a lower zone (12) in which an exothermic Claus reaction takes place. Thereafter, the gas stream is cooled in zone (11) to below its dew point so that the mixture of liquid sulfur and gas passes via a droplet separator (22) into the base of the column. Liquid sulfur, at \= 125 deg C, i.e. above the crystallization temperature, passes through a drain (20), whilst the gas passes sideways through an output line (21). The process is carried out at 1.1 - 3.0 bar, using air as the cooling medium which is circulated by a fan (17) through the cooler (18), and rises up the column so that, at its highest temperature, it reheats the incoming gas stream in zone (9).

Title: Variously colored tennis court marking line as fibers or plates
Inventor: DUONG GILBERT
IPC: A63C19/06
Filed: 1998-07-02
Abstract: The flexible fibers or plates fixed to the base layer reset flexibly with delay once bent back and are made up of parts near to and far from the base, with the near parts all of one color and the far parts also all of one but different color. As the fibers or plates lie close together when stretched out, only the parts far from the base show. The far parts are thickened to form a head and the base layer is of the same color as the fiber etc. parts near the base. Mechanical forces reach the further parts via a transparent cover layer and the force impact thus registers on the spot.   The reset time for the far parts depends on the material used and the dimensions of the transparent cover.
