Publication number: 20240157184Abstract: A flame arrester is disclosed that includes one or more arrester elements each having a cell element that is configured to form a non-linear flow path through the arrester element. Cell elements can be formed from first and second strips that are wrapped together around a central core. Each of the first strip and the second strip can be configured as corrugated strips, with the first strip defining first corrugations and the second strip defining second corrugations. The first and second corrugations can be angled relative to one another to form a plurality of crossed flow paths through the cell element.Type: ApplicationFiled: November 11, 2022Publication date: May 16, 2024Inventor: Juan M.

Patent number: 10344880Abstract: An actuator assembly for use with a shut-off valve in a transport or storage system. The assembly is configured to be operatively coupled to a stem of the valve for controlling fluid flow therethrough. The assembly includes a mounting bracket coupled to the bonnet, a mounting sleeve coupled to the stem and movable relative to the mounting bracket, and an actuator having a body and an inlet formed in the body. The body is defined by a first body portion coupled to the mounting bracket and a second body portion coupled to the mounting sleeve and movable relative to the first body portion to expand or contract the body. The inlet is adapted to receive pressurized fluid; the body expands or contracts responsive to the pressurized fluid, and responsive to the expansion or contraction of the body, the mounting sleeve moves relative to the mounting bracket, thereby moving the stem.Type: GrantFiled: May 6, 2016Date of Patent: July 9, 2019Assignee: EMERSON PROCESS MANAGEMENT REGULATOR TECHNOLOGIES, INC.Inventors: Juan M.

Patent number: 10132418Abstract: A shut-off valve for use in a fluid transport or storage system includes a body defining an inlet port, an outlet port, and a fluid flow passageway extending between the inlet port and the outlet port, a seat arranged in the body adjacent the outlet port, a shaft at least partially disposed in the body, and a control assembly disposed in the body and operatively coupled to the shaft. The control assembly is movable between a closed position, in which a portion of the control assembly sealingly engages the seat to seal the outlet port, and an open position, in which the control assembly is spaced away from the outlet port and substantially outside of the fluid flow passageway, such that the control assembly provides minimal flow-restriction to fluid flowing through the fluid flow passageway.Type: GrantFiled: May 6, 2016Date of Patent: November 20, 2018Assignee: EMERSON PROCESS MANAGEMENT REGULATOR TECHNOLOGIES, INC.Inventor: Juan M.

Patent number: 9334974Abstract: A pilot operated pressure relief valve includes a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway. A valve plug may be disposed within the fluid passageway, the valve plug cooperating with a valve seat to control fluid flow through the fluid passageway. An actuator may be connected to the valve plug, the regulator biasing the valve plug towards the valve seat. A pilot assembly may include a first pilot valve and a second pilot valve, wherein the pilot assembly directs fluid pressure upstream of the valve plug to one of the first and second pilot valves. When the upstream fluid pressure exceeds a predetermined level, the valve plug moves away from the valve seat allowing fluid to flow through the fluid passageway.Type: GrantFiled: September 27, 2013Date of Patent: May 10, 2016Assignee: EMERSON PROCESS MANAGEMENT REGULATOR TECHNOLOGIES, INC.Inventors: Juan M. Diaz, Khashayar A. Nashery, Bryan J. Steger

Publication number: 20110220304Abstract: A torsion coil spring type counterbalance system for an upward acting door includes one or more sleeves disposed over or within the spring coils and engageable with a predetermined number of spring coils during operation of the spring to modify the spring rate to more closely approximate the required counterbalance forces exertable on the door when the door moves between open and closed positions. The counterbalance system is particularly advantageous for upward acting sectional doors which have one or more sections which are heavier than the other sections, including an uppermost section which may be heavier due to the provision of windows or other structural features of the section.Type: ApplicationFiled: May 23, 2011Publication date: September 15, 2011Applicant: Overhead Door CorporationInventor: Juan M.

Patent number: 7364051Abstract: An electrical motor rotatably drives a motor shaft, and a helical rib radially extends from the shaft. The helical rib supports a number of balls, and forms a channel to accommodate the balls. The balls are dropped from the helical rib when the balls reach the bottom of the helical rib. Several targets are affixed to the shaft. A sensor is located adjacent to and apart from the shaft, and is positioned in close proximity to the targets. The sensor senses each target as each target rotates past the sensor. The number of targets sensed per revolution of the shaft is equal to the number of balls dropped from the helical rib per revolution of the helical rib. A counter in data communication with the sensor displays the number of targets sensed, and thus displays the number or balls dropped from the helical rib.Type: GrantFiled: February 24, 2004Date of Patent: April 29, 2008Assignee: S.P.M.

Patent number: 6945569Abstract: A union for connecting two tubular members. The first tubular member has an external flange, and the second tubular member has a set of external threads. An annular nut surrounds the first tubular member. The nut has an internal flange that surrounds the first tubular member, and a set of threads to engage the threads of the second tubular member. Arcuate segments are circumferentially mated between the internal flange of the nut and the external flange of the first tubular member. A flat conical surface on the inner side of the segment comes into contact with a flat conical surface on the outer side of the external flange. Curved conical surfaces tangentially align with and extend from the flat conical surfaces on the segment and the external flange. Cylindrical surfaces tangentially align and join the curved conical surfaces on the segment and the tubular member.Type: GrantFiled: April 28, 2004Date of Patent: September 20, 2005Assignee: S.P.M.
