Title: Process for the extraction of fragrances from the vanilla capsule
Inventor: SCHUTZ ERWIN DR
IPC: A23L27/10
Filed: 1982-08-26
Granted: 1986-04-24
Abstract: 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 DEG  and 30 DEG  C. and pressures of 80 to 350 bar, and producing the separation of the extract at temperatures of 0 DEG  to 30 DEG  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.

Abstract: A burst panel assembly (10) for normally covering a vent opening of structure which defines an area to be protected from the buildup of dangerously high internal pressures has two frangible panels (l2, l6) disposed in spaced, face-to-face relationship along with a core of expanded polyurethane foam (48) which functions to dampen vibrations received from the structure and transmitted to the frangible panels (l2, l6). The foam (48) is introduced in an initially flowable condition into the space (20) between the panels (l2, l6) and thereafter expands while curing to a solidified configuration for continuously exerting pressure on both of the panels (l2, l6), to thereby substantially reduce the fatigue stress that would otherwise occur along lines of weakness of burst patterns (22) that are formed in both of the panels. In a preferred method of construction of the burst panel assembly, pressurized air is initially introduced into the space between the panels (l2, l6) to shift one of the panels outwardly to a pre-bulged configuration, and subsequently a negative pressure is applied to the outside face of the opposite panel to shift the same in an outward direction while filling the space (20) with the initially flowable foam material (48), so that the foam expands to a configuration larger than would be otherwise possible and is subsequently "pre-stressed" against the same panel when the negative pressure is relieved. The foam material (48) when cured strengthens the assembly by providing support to the central portions of the frangible panels (l2, l6), and also the foam (48) is compressible and somewhat resilient so that vibrations transmitted to the frangible panels are effectively dampened. The burst panel assembly is particularly useful for protecting relatively low pressure equipment such as baghouses, dust collectors and dryers.
