International Classification:

F16L 19/00

US Classification:

285338, 2853825

Abstract:

An adapter mount for attaching to a fitting tube includes an adapter tube having an outer circumferential surface; a first expandable ring placed on the outer circumferential surface of the adapter tube and comprising of elastic material for expanding and fitting to the inner surface of the fitting tube; an adjustment ring configured to be threaded to the adapter tube to generate a rotational threading force; a compression ring for translating the rotational threading force from the adjustment ring to a longitudinal compressing displacement of the first expandable ring, causing an outer surface of the first expandable ring to fit to the inner surface of the fitting tube; and a stop attached to the adapter tube for preventing the adjustment ring from separating from the adapter tube.

Abstract:

The present invention provides a method for preparing DMF for sucralose production, including, e. g. , isolating DMF from a composition comprising DMF, water, and methanol, using a single-tower rectification system. In various embodiments of the present invention, the composition, after the removal of water and methanol, may be further dried/dehydrated, such as, by using a dehydration agent and/or filtration. The resulting substantially pure DMF may comprise at least about 98-99% DMF. The present invention further provides a method of preparing a composition comprising anhydrous sucrose for sucralose production, which may comprise mixing regular sucrose with a water-containing DMF composition, and drying the resulting sucrose-DMF composition. Also provided is a single-tower separation system for isolating DMF from a composition comprising DMF, water, and methanol.

International Classification:

F16L 19/00

US Classification:

285338, 285346, 42119, 359829

Abstract:

An adapter clamp for clamping an adapting tube. The adapter clamp includes: an adapter tube; a first resilient ring placed in the inner circumferential surface of the adapter tube and including elastic material for expanding inward and clamping to the outer surface of the adapting tube; a hollow adjustment ring configured to be threaded to the inner surface of the adapter tube to generate a displacement force; and a compression ring providing minimum friction resistant for translating the displacement force from the threading hollow adjustment ring to a longitudinal compressing displacement of the first resilient ring, causing an inner surface of the first resilient rings to fit to the outer surface of the adapting tube. The adapter clamp also includes a second resilient ring placed in the inner circumferential surface of the adapter tube; and a spacer placed on the inner circumferential surface of the adapter tube.
