US Classification:

96165, 95244, 96215, 96207, 137176

Abstract:

An air eliminator including a housing having first and second portions, the housing defining: a chamber, an inlet in fluid communication with the chamber; an outlet in fluid communication with the chamber; and an axis extending from the first portion to the second portion, a float assembly connected to the first portion of the chamber for releasing air from the chamber, and degassing disks stacked within the chamber along an axis, wherein each disk includes a plurality of rings such that the degassing disks cause micro gas pockets in water passing through the chamber to combine into relatively large and buoyant air pockets that collect and pass along the axis to the float assembly for release.

International Classification:

US Classification:

701 49

Abstract:

A system of inflatable air cells is constructed and installed in a seat at locations that are strategic to the comfort of the user. The air cells are connected to a pump through a manifold which sequentially connects each cell independently to the pump. The manifold controls the flow of fluid in the air cell distribution system by means of a system of valves and senses the pressure in each cell by means of a transducer. A microcomputer is programmed with data representing a desired comfort level for each of the air cells. By sequentially activating individual manifold valves, a pressure signal from the transducer can be generated for each cell. The pressure signals are received by the microcomputer and are correlated with the predetermined comfort data to generate a control signal which activates the pump. In this manner each of the cells can be individually inflated or deflated to the desired pressure level. By varying the number and location of the cells the system becomes responsive to the localized pressures exerted on the body for a great variety of users.

International Classification:

B60R 2116

US Classification:

280732

Abstract:

A releasable latch (50) is provided for a door assembly (14) having an outer skin member, a foam backing member, and an inner door member. The door assembly conceals an airbag restraint system having a housing, an airbag and a gas generator producing an inflatant for inflating the airbag for deploying the airbag through the door assembly. The releasable latch has a closed U-shaped end that is press fit in an open U-shaped end on a retainer member on the housing to hold the door assembly in a mating relationship to interior trim parts. The inner door member is engaged during initial inflation of the airbag to displace the door assembly so as to bend the inner door member at a hinge joint between the outer cover member and the interior trim part and the press fit between the closed U-shaped end and the open U-shaped end provides easy opening of the door assembly as the airbag is inflated.

Steven CASTRIGNO - Chester NH, US

International Classification:

F16K 15/03

Abstract:

A relief valve has a valve body, a plunger assembly coupled to the valve body for selectively opening and closing the relief valve, and a support member secured to the valve body. A lockout lever is against the support member, forming a vertex. A spring rod is coupled to the lockout lever, and a spring is coupled to the spring rod, providing a bias force against the plunger assembly to normally close the relief valve. In a lockout position, the lockout lever is moved to pivot on the vertex against the support member to further compress the spring, which increases the bias force and, in turn, a cracking pressure of the relief valve.

Abstract:

Fluid detection systems and methods using the same are disclosed. In embodiments the fluid detection systems include a sensor module and an electronics module. The sensor module includes a sensor housing that includes a liquid flow path and a sensor element disposed around at least part of the liquid flow path. The sensor element can detect a capacitance of the liquid flow path and provide a sensor signal to a controller in the electronics module. The electronics module can determine a detected capacitance in the liquid flow path based at least in part on the sensor signal, and can determine whether a wet event has occurred based on a comparison of the detected capacitance to a threshold capacitance. Methods using the fluid detection systems and fluid supply systems including the fluid detection systems are also disclosed.

Assignee:

Watts Regulator Co. - North Andover MA

International Classification:

F16K 17/04
F16K 31/56

Abstract:

A relief valve provides pressure relief when a fluid line exceeds a predetermined pressure. The valve includes a body which defines a cavity between inlet and outlet flowpaths. The valve includes a lever arm, which pivots around a pivot point as the valve changes between open and closed positions. A plunger assembly is disposed in the cavity and seals the cavity from the inlet and outlet flowpaths in the closed position. Fluid pressure from the inlet flow path causes the plunger assembly to contact the lever arm to urge the lever arm to rotate. The lever arm engages a spring at a further distance from the pivot point than the plunger assembly, the spring resisting pivoting of the lever arm and urging the valve to remain in the closed position unless a predetermined pressure is exceeded.

Abstract:

A fusion pipe assembly includes a fitting having at least one open end with a fusion region. A fusion pipe has a proximal end with a fusion region so that when the proximal end is inserted into the at least one open end, the fusion regions can be fused together. The fusion pipe has a distal end for mechanically coupling in a pipe network. A collar is inserted in the distal end and has an outer diameter approximately equal to an inner diameter of the distal end so that the collar strengthens the distal end. Preferably, the collar extends into the at least one open end of the fitting.
