David James Westwater - Albion IA, US

International Classification:

F16L 55/027

US Classification:

251127

Abstract:

Apparatus to increase the fluid flow in a valve are disclosed. An example apparatus includes a valve body having a fluid passageway, a valve cage located in the passageway and including a wall having an outer surface and an inner surface defining a cage bore with an axis. The wall has at least one flow zone comprising a plurality of through openings, each through opening extending between the inner and outer surfaces to define an opening axis extending through the wall. The opening axis is disposed at a non-orthogonal angle with respect to a reference plane disposed orthogonal to the axis of the cage bore. A valve plug is axially slidable in the cage bore.

Aaron Perrault - Marshalltown IA, US

International Classification:

F16K 1/00

US Classification:

251333

Abstract:

Apparatus to align a closure member and valve stem for use with valves are described. An example valve includes a stem and a closure member having a first aperture to receive at least a portion of the stem. The example valve further includes a positioning member that has a first portion and a second portion. The first portion has a first cross-section and the second portion has a second cross-section that is greater than the first cross-section and an area between the first portion and the second portion forms a positioning surface to engage the first aperture of the closure member to align the stem and the closure member. A fastening member couples the stem to the closure member.

International Classification:

F16K 13/00

US Classification:

251333

Abstract:

A valve seat apparatus for use with fluid valves is described. An example valve seat apparatus includes a flexible seal disposed between a cage and a valve body such that an outer seating surface of a closure member slidably coupled to the cage slidingly engages the flexible seal to prevent fluid flow through the valve body when the valve is in a closed position and an end of the closure member is not driven into abutting engagement with another seating surface when the valve is in the closed position.

International Classification:

G01K 7/00
G01K 1/08

US Classification:

374163, 374208, 374E01011

Abstract:

A temperature transmitter includes a dual-compartment housing and a head-mount temperature transmitter electronics module. The dual-compartment housing has a first compartment and a second compartment. The first compartment is configured to receive field wiring at a terminal block through at least one conduit. The first and second compartments are separated except for an electrical feedthrough therebetween. A head-mount temperature transmitter electronics module is disposed in the second compartment and is operably coupled to the terminal block in the first compartment.

International Classification:

H04B 1/04
H04B 3/54

Abstract:

A process variable transmitter includes a sensor terminal block having a plurality of sensor line connectors to connect to sensor lines from at least one process variable sensor. The sensor terminal block defines a reception area that in a first instance accepts a removable standard power terminal block and in a second instance accepts a removable transient power terminal block. One of the removable standard power terminal block and the removable transient power terminal block is inserted in the reception area of the sensor terminal block.

International Classification:

H05K 5/06

US Classification:

361736, 361728

Abstract:

A field device for use in an industrial process includes a housing having a cavity formed therein. A humidity-sealed electronics module has a first compartment formed therein and is positioned in the cavity. The humidity-sealed electronics module includes a seal board. The seal board separates the first compartment of the humidity sealed electronics module from a second compartment in the housing. A first electrical component in the first compartment is mounted to the seal board and a second electrical component in the second compartment is electrically connected to the first electrical component.

International Classification:

G01K 1/08

US Classification:

374152

Abstract:

A process sensor assembly comprises a hollow protective housing, a temperature sensor, a process transmitter, and a transient protector. The temperature sensor includes a probe extending out of the hollow protective housing to a sensing location, and a top plate movably secured to the hollow protective housing so as to allow travel within the hollow protective housing with vibrations of the probe. The process transmitter is configured to process and transmit sensor signals from the temperature sensor, and is retained on the top plate to move with the temperature sensor within the hollow protective housing. The transient protector is configured to condition power for to the process transmitter, and is anchored to the process transmitter so as to move with the process transmitter within the hollow protective housing.
