摘要： The invention relates to an apparatus for analyzing reaction systems with a liquid phase (13) and a gas phase (15), the apparatus (1) comprising at least two tank reactors (3), a common feed line (5), a common drain line (25) for the liquid phase and a common drain line (21) for the gas phase, each tank reactor (3) being connected to the common feed line (5) by a supply line (7), to the common drain line (25) for the liquid phase by a liquid withdrawal line (27) and to the common drain line (21) for the gas phase by a gas withdrawal line (23), wherein the pressure in each tank reactor (3) is controlled by one of:
(a) a pressure control (31) in the common feed line (5);
(b) a pressure line (29) which is connected to the gas space of each tank reactor (3);
(c) a pressure control (31) in the common drain line (21) for the gas phase and a flow restrictor (33) in the common drain line (25) for the liquid phase or a pressure control (31) in the common drain line (25) for the liquid phase and a flow restrictor (33) in the common drain line (21) for the gas phase; or
(d) a pressure line (29) which enters into the common drain line (25) for the liquid phase or into the common drain line (21) for the gas phase.
The invention further relates to a process for analyzing reaction systems in such an apparatus.-

摘要： A gas regulator includes a valve chamber body that houses two valves of the regulator. Valve elements that move to open and close the two valves are received via a same opening into the valve chamber body, which is closed by a plug. The plug can define a first valve seat as well as a piercing element used to pierce a compressed gas cylinder. A retainer can hold a gasket at a valve seat as well as provide a bore or other support for a valve element and valve element spring.

摘要： An apparatus for controlling precursor flow. The apparatus may include a processor; and a memory unit coupled to the processor, including a flux control routine. The flux control routine may be operative on the processor to monitor the precursor flow and may include a flux calculation processor to determine a precursor flux value based upon a change in detected signal intensity received from a cell of a gas delivery system to deliver a precursor.

摘要： A back pressure regulator (“BPR”) includes a pressure housing that at least partially defines a flow chamber that the liquid flows through and the BPR has an adjustable restriction that varies with the flow rate to maintain an upstream liquid pressure. The pressure housing is contoured to distribute the liquid flow to provide radial flow into the adjustable restriction from circumferentially about the adjustable restriction. The pressure housing includes ramped and curved side passages that guide the flow and ridges that divide the flow and prevent internal collisions between the flow. A flow deflector extends into the chamber outlet to prevent the radial flows through the annular restriction from colliding. The flow deflector redirects the flows to smoothly recombine in the chamber outlet.

摘要： A pressure reference resetting structure of an inflatable mattress, the inflatable mattress contains a valve connected with an end of the inflatable mattress, an inflatable air pump connected with the valve, and the valve being connected with a pressure detection pipe which is coupled with a pressure sensing element. The valve includes an air orifice communicated with the pressure detection pipe so that the pressure sensing element detects a pressure of an external environment via the pressure detection pipe and the air orifice, and a reference pressure of the inflatable mattress is reset to inflate the inflatable mattress based on the reference pressure.

摘要： A refrigerant leak management system includes a controller is configured to receive a signal indicative of a refrigerant pressure within a refrigerant circuit and determine whether the refrigerant pressure is indicative of a refrigerant leak in the refrigerant circuit. In response to determining that the refrigerant pressure is indicative of the refrigerant leak, the controller is configured to activate a fan configured to motivate air proximate the refrigerant circuit.
