Abstract: An apparatus and a method are provided for a controlled atmosphere display case for prolonged storage of plant-based contents within the case. The controlled atmosphere display case includes a rigid housing having an interior cavity. An inert gas supply provides an inert gas to the interior cavity. The inert gas may be nitrogen, or a combination of inert gases that includes nitrogen. An inlet valve conveys the inert gas into the interior cavity. A vacuum pump and the inert gas supply cooperate to create a nitrogen flush that replaces oxygen-rich air within the interior cavity with nitrogen gas. A pressure gauge actuator regulates the concentration of nitrogen gas within the interior cavity. A refrigeration unit controls temperature and moisture within the interior cavity. The nitrogen flush advantageously extends the shelf life of plant-based produce that may be stored within the interior cavity.

Abstract: A method of producing stone set jewelry includes the step of forming at least one affixation groove within the stone to be set in the jewelry. A stone to be set with the present method should have an upper and a lower portion which is at least substantially entirely hidden from view when the upper portion of the stone is viewed. In accordance with the present method the affixation groove should be formed in the lower portion of the stone such that it too is hidden from view when the upper portion of the stone is viewed. A heat setting method is disclosed for improving the bond between the pavilion of the stone and the wax model used in the casting process. The method also includes the deposition of a mounting material within the affixation groove by applying a conventional casting method.

Abstract: A group of 7,8-dihydroxy-2,3,4,5-tetrahydro-1H-3-benzazepines with structures containing a thienyl or furyl ring at position 1 which have dopaminergic activity. Particular species of this group include 7,8-dihydroxy-1-(5'-methyl-2'-thienyl)-2,3,4,5-tetrahydro-1H-3-benzazepine and its dimethyl ether derivative, 7,8-dihydroxy-1-(2'-thienyl)-2,3,4,5-tetrahydro-1H-3-benzazepine and its dimethyl ether as well as 7,8-dihydroxy-1-(3'-thienyl)-2,3,4,5-tetrahydro-1H-3-benzazepine and its dimethyl ether.
