Embodiments described herein provide ampoule assemblies to contain, store, or dispense chemical precursors. In one embodiment, an ampoule assembly is provided which includes an ampoule containing a first material layer disposed on the outside of the ampoule and a second material layer disposed over the first material layer, wherein the first material layer is thermally more conductive than the second material layer, an inlet line in fluid communication with the ampoule and containing a first man...

A grain dropping passage constituted below a husking unit(D) serves as a winnowing room(A). A winnowed grain conveyor(1) is provided as the sole conveyor below the winnowing room(A). A winnowing wind blown by a winnowing fan(F) through a blowing room(B) passes through below the winnowed grain conveyor(1) and then rises in the winnowing room(A). The grains mixed with hulls and others are winnowed in the winnowing room(A) so as to be sorted into two kinds: winnowed grains to be received by the win...

An apparatus and method for reducing the circling upward movement of a product such as waste paper entrained in a carrier stream. The invention includes a product rake placed within a discharge chute to capture and direct product within the product flow. A further aspect of the invention includes a relief valve integrated into the discharge chute to alleviate pressure in the discharge chute and allow excess air to be relieved from the discharge chute to control the product flow.

This is a system and procedure that uses either a hand pump system or an electric pump system to drain fresh water or sea water out of a marine engine, and then uses either the hand pump system or the electric pump system to install fresh water or other liquid chemicals into the marine engine, and also uses either the hand pump system or the electric pump system to recover the liquid chemicals from the marine engine.

A high purity chemical delivery system is provided that connects a high purity chemical container to a high purity chemical utilization point and that comprises three manifolds, each of the manifolds having a plurality of diaphragm valves. The inventive system enables rapid clean out and purge after the container is replaced by means of a plurality of vacuum and purge cycles, which remove residual chemical and entrapped impurities while reduced manufacturing downtimes compared with systems in th...

An emergency utility backup system, for a building normally supplied with culinary water, electric power and natural gas by public utilities, includes at least one water storage reservoir having an upper input coupled to a public water utility main line; an electric generator powered by an internal combustion engine; and an electric air compressor having a compressed air storage tank which provides elevated air pressure to the water storage reservoir(s) in the event that water pressure from the ...

A system for providing gas to a container includes a source of gas under pressure, a container, and a pressure regulating device. The pressure-regulating device includes an inlet intended to be connected to a source of the gas under pressure, an outlet, connected by a duct to the inlet and intended to be placed in communication with the container, a first valve for limiting the pressure at the outlet to a predetermined maximum value Ps, which valve is a delivery valve placed in a first passage w...

An aeraulic separator for automatically separating materials into three batches of different weights or shapes having a chamber under a slight depression with an inlet opening, two perforated inclined planes with an inclination of angle .alpha. and .beta.,.beta. being greater than or equal to .alpha., supplied with air under pressure, three outlet openings for the three batches, and a deflector. The heavy materials drop through the first opening adjacent the second inclined plane. The materials ...

A system for rapidly building an air cushion over liquid in a tank, without requiring an air compressor for this purpose. During normal operation the air cushion over the liquid is maintained at a given magnitude and pressure by cyclical operation of an air-supply tank at a given normal rate. This air-supply tank is operated by the method and apparatus of the invention at a faster than normal cyclical rate for the purpose of rapidly building up the air cushion when the liquid-supply tank which h...

An on-board inert gas generating system includes a flow control valve modulated according to changes in ambient conditions to minimize changes to oxygen content within a fuel tank. The quality of the nitrogen-enriched air stream that is provided by the air separation module varies in response to flow. Higher flow rates through the air separation module removes less oxygen relative to lower flow rates. The amount of flow through the air separation module that produces the least amount of oxygen w...
