Abstract: THE METHOD OF VAPORATION FEATURING HUMIDIFICATION IS EFFECTED IN A CHAMBER MAINTAINED AT A DOWNWARDLY INCRESING TEMPERATURE GRADIENT. THE LIQUID BEING TREATED AND A VAPOR CARRIER GAS ARE PASSED DOWNWARDLY THROUGH THE CHAMBER WHERE THE CARRIER GAS IS ENRICHED IN VAPOR FROM THE LIQUID. THE ENRICHED CARRIER GAS EXITING FROM THE BOTTOM OF THE CHAMBER IS MOVED UPWARDLY ALONGSIDE THE CHAMBER AND IN HEAT TRANSFER RELATION WITH THE FLUIDS WITHIN THE CHAMBER. HEAT IS APPLIED TO THE BOTTOM PORTIONS OF THE CHAMBER TO ASSURE THE DESIRED TEMPERATURE GRADIENT. CONDENSATION OCCURS ON THE OUTSIDE OF THE CHAMBER. THIS CONDENSATE AND THE CONCENTRATED LIQUID CAN BE RECOVERED. THE HEATED LIQUID CONCENTRATE EXITING THE BOTTOM OF THE CHAMBER MAY BE FURTHER TREATED.

Abstract: A device and method particularly suitable for separating particulate matter in a molten salt or molten metal bath from the bath. The device comprises a unitary bowl and pump structure adapted to be immersed into and rotated in a pool of the bath, and to draw into the bowl the bath and particulate matter when the bowl is rotated. With rotation of the bowl, the particulate matter, in large measure, is collected in a concentrated form in the bowl while the bath, which is now largely depleted of particulate matter, is discharged from the bowl. To remove the particulate matter, and any bath entrapped therewith, from the bowl, the bowl is removed from the bath and a blade means is inserted into the bowl to scrape the particulate matter from the bowl. The particulate matter falls from the bowl through an opening provided in the lower end thereof. After the particulate matter is removed from the bowl, the bowl is returned to the bath for another cycle of collection and particle removal.
Abstract translation: 特别适用于从熔池中分离熔融盐或熔融金属浴中的颗粒物质的装置和方法。 该装置包括一个整体的碗和泵结构，其适于浸入浴池中并在其中旋转，并且当碗旋转时，将碗和微粒物质吸入碗中。 随着碗的旋转，在很大程度上，颗粒物质以浓缩形式收集在碗中，而现在大量耗尽颗粒物质的浴从碗排出。 为了从碗中除去颗粒状物质和与其夹带的任何浴液，将碗从浴中取出，并且将刀片装置插入到碗中以从碗中刮除颗粒物质。 颗粒物从碗中通过设置在其下端的开口落下。 在从碗中取出颗粒物质之后，将碗返回到浴中以进行另外的收集和除去颗粒的循环。

Abstract: A rigid panel and a method of making the same, the panel being comprised of a relatively thin gauge sheet of metal and at least one rigid, stiffening member welded to the rear face of the metal sheet. The stiffening member is welded to the sheet by depositing weld metal in spaced apart openings provided in the stiffening member, the openings being located along the bottom of a longitudinally extending groove provided in the stiffner. Opposed side walls of the groove diverge outwardly from the bottom thereof to the surface of the stiffener remote from the metal sheet to provide the groove with a relatively wide dimension at the remote surface, and a relatively narrow dimension at the bottom of the groove and adjacent the metal sheet.
