International Classification:

F28D 1/053
F28F 9/013
F16M 11/12

Abstract:

An apparatus includes a heat exchanger configured to be positioned around and coupled to a multi-axis gimbal. The heat exchanger includes an inlet configured to receive fluid containing heat generated by an equipment package carried by the gimbal. The heat exchanger also includes multiple heat rejection interfaces configured to reject the heat from the fluid into surrounding air in order to cool the fluid. The heat exchanger further includes an outlet configured to provide the cooled fluid from the heat exchanger. The heat rejection interfaces of the heat exchanger extend around the heat exchanger and are configured to reject the heat from the fluid regardless of a direction in which the gimbal is pointing the equipment package.

International Classification:

F04B 53/16
F16K 27/00
F16L 25/14
F04B 53/10

Abstract:

A self-centering valve adapter connection assembly includes a first equipment flange that is connected to a second equipment flange with an adapter ring. The adapter ring includes a first longitudinal flange with a tapered inner surface and a cylindrical outer surface. The adapter ring aids in centering the first and second equipment flanges while smoothing a fluid flow corridor between the first equipment flange and the second equipment flange.

International Classification:

F16K 1/02
F16K 31/126

Abstract:

A fluid regulator having a valve body defining an inlet, an outlet, a loading port, an access port, and a loading chamber disposed within the valve body and coupled to the loading port. A valve assembly is at least partially disposed between the inlet and the outlet and in communication with the loading chamber and is adapted to cooperate with the loading chamber to adjust fluid flow at the outlet by adjusting a fluid flow rate between the inlet and the outlet. A restrictor is at least partially disposed within the access port and the loading chamber and the valve assembly are adapted to be responsive to a change in loading pressure such that a modified rate is achieved and the restrictor is adapted to adjust a response speed in which the modified rate is achieved.

International Classification:

F16K 1/52
F16K 47/08

Abstract:

A cage for a control valve has a circumferential wall having inner and outer surfaces, a plurality of first passages formed through the wall, and a plurality of second passages formed through the wall. The plurality of first passages each include an upper portion and a lower portion that is tapered in a direction away from the upper portion. The plurality of second passages are positioned between adjacent lower portions of first passages.

International Classification:

F16K 1/52

Abstract:

A fluid flow valve includes a valve body, a loading chamber disposed within the valve body, a valve assembly, and a restrictor unit. The valve body defines a flow inlet, a flow outlet, and a loading chamber inlet. The loading chamber is coupled to the loading chamber inlet. The valve assembly is at least partially disposed between the flow inlet and the flow outlet and is in communication with the loading chamber. The valve assembly is adapted to cooperate with the loading chamber adjust fluid flow at the flow outlet by adjusting a fluid flow rate between the flow inlet and the flow outlet. The restrictor unit is at least partially disposed within the loading chamber inlet. The loading chamber and the valve assembly are adapted to be responsive to a change in loading pressure to achieve a modified fluid flow rate. The restrictor unit is adapted to adjust a response speed in which the modified fluid flow rate is achieved.

Mark A. Michnevitz - McKinney TX, US

International Classification:

F16K 17/36
F16L 29/00

Abstract:

A bi-directional hose break-away assembly includes a first adapter section and a second adapter section that are operatively connected by a hose section. A first valve assembly is disposed within the first adapter section and a second valve assembly is disposed within the second adapter section. The first and second valve assemblies are operatively connected by a stem connector so that the first and second valve assemblies will close in the event a maximum tensile load is exceeded, thereby preventing spillage of liquefied chemicals.
