Title: Stopper for road-side fastening hole for road-sign in snowfall time
Inventor: HATTORI EIICHI
IPC: E01F9/553
Filed: 1994-02-28
Abstract: PURPOSE:To prevent the deposition of earth and sand during snowfall time by fastening a synthetic resin-made stopper which is conforming to a fastening hole from which a road sign is removed. CONSTITUTION:A stopper 1 for a road side-fastening hole is formed with synthetic resin elastomer or rubber and has proper strength to screw in a threaded portion 3a of a fastening part 3 embedded in a road. The exposed height of the stopper 1 over the road is specified to be identical with the road surface or a minimum height must be selected. The shape of a disk or a polygon is acceptable as the outside shape. The shape of a threaded fastening recessed part 2 is arbitrarily selected from a quadrangle or an octagon as well. During a snowfall time, a road sign is removed from a road-side fastening part and the conforming synthetic resin, synthetic resin elastomer or the like stopper is screwed in the road-side fastening hole, thereby eliminating the deposition of earth and sand into the fastening hole. As a result, it is easy to mount the road sign after the snow has disappeared, while it is effective to protect the threaded part of the fastening hole from being rusted.

Title: Desulfurization of molten iron
Inventor: KONDOU ATSUSHI
IPC: C21C1/02
Filed: 1978-03-14
Abstract: PURPOSE:Desulfurizing material consisting of converter slag and carbon material is added between the tap hole of the blast furnace and skimmer thereby effecting low cost predesulfurizing of molten iron. CONSTITUTION:A highly basic converter slag powder with basicity of more than 3.5 containing as much as 30 to 50% of Cao is used in amount of 50 to 60% to be mixed with 40 to 50% of powder of carbon materials such as coke and coal to form a desulfurizing agent. When molten iron is tapped from the blast furnace, such desulferizing mixture is added to the iron flow between the tap hole and skimmer, in an amount of 15 to 20 kg per 1 ton of molten iron. FeS in the iron is reacted with CaO in the desulfurizing agent, becoming CaS and removed from the molten iron to be formed into slag, FeO formed in this process is reduced by carbon into Fe, which is melted in molten iron. Accordingly, dusulfurizing reaction equilibrium by FeO increase is unbalanced thereby to cause the desulfurizing reaction to continue. The raw mterial is cheap and has no danger of hazard.
