    摘要: A process for recovering flavoring substances from the vanilla capsule with carbon dioxide under fluid conditions is described, which consists in performing the extraction at temperatures between 10.degree. and 30.degree. C. and pressures of 80 to 350 bar, and producing the separation of the extract at temperatures of 0.degree. to 30.degree. C. and pressures of 30 to 60 bar. In this manner it is possible by a one-step process to extract all of the flavoring substances of the vanilla capsule with the recovery of a highly concentrated vanilla flavoring, and to obtain a material which is considerably superior to the products obtained by conventional extraction with organic solvents.

    摘要: It is known to contact molten cast iron with various treating agents in the casting mold in order to influence the base structure or the form of the graphite. Such casting molds for making castings of cast iron containing vermicular and/or spheroidal graphite are provided with an intermediate chamber, which is provided in the pouring system between the pouring gate and the ingate to the casting mold proper. That intermediate chamber serves to receive the graphitizing agent and to contact it with the molten cast iron. To permit a functional adaptation of the chamber surface area or the surface area of the treating agent contained in the chamber to the pouring gate, which changes as the pouring proceeds, the casting mold is provided with a frustopyramidal intermediate chamber which has a rectangular base disposed in the parting plane of the mold.
