Title: Apparatus and process for the production of acetylene
Inventor: BUNGER JAMES W
IPC: C01F11/02
Filed: 1990-10-25
Granted: 1998-12-22
Abstract: A two-staged process for producing acetylene and calcium chloride from calcium carbide (12) and water (12) has two successive reaction steps. In step Number 1, calcium carbide is charged into an entrained flow-type reactor (10) vessel containing water. The reaction which follows proceeds to about 60-90 % completion. The entrained reaction products and the unreacted feed material are carried over to a secondary reactor (16) to complete the reaction, and the acetylene gas is drawn off (26). Calcium hydroxide product is removed from the reactor (23) and reacted with hydrogen chloride to form calcium chloride. Heat generated by the exothermic reactions of water with calcium carbide and HCI with calcium hydroxide is used to dry the calcium chloride product and improve its value. In the presence of excess of water, the calcium carbide-water reaction is effectively a first order, irreversible reaction.

Title: Method and apparatus for the production of mineral wool, and mineral wool thereby produced
Inventor: BATTIGELLI JEAN
IPC: B28B1/00
Filed: 1992-08-20
Granted: 1999-10-26
Abstract: Mineral material, particularly of the basalt type, is fiberized by internal centrifuging in a spinner (1') having a peripheral wall (19) with a multiplicity of orifices through which the melt may emanate into the environment where a hot gas blast attenuates the melt cones emanating from the orifices to fibers. As such mineral material has a high melting point or liquidus temperature, and low viscosity at the liquidus temperature, a high proportion of unfiberized particles is likely to be produced. However, the production of mineral wool with good fiber fineness and largely free of unfiberized particles surprisingly is possible if the cone lengths and the configuration of the gas flows generated around the spinner are such that the majority of the filament forming cones emanating from the spinner orifices intersect the isotherm corresponding to a viscosity of 100 poises, or otherwise reach into a zone cooled down to a temperature corresponding to a viscosity of more than 100 poises. In practice, such a configuration of the gas flows is produced by an outer annular blower (24) complementing the external annular burner (13) which produces jets of cool air so as to bring low-temperature isotherms in close vicinity of the peripheral wall (19) of the spinner (1') where the tips of the cones reach into such cool zone so as to increase the viscosity at the tip of the cones to avoid breakage of the filament to be attenuated.
