Appl. No.:

10/354339

Inventors:

Peter Tartaglia - Butler NJ, US

Assignee:

Marotta Scientific Controls, Inc. - Montville NJ

International Classification:

B64F001/02

US Classification:

244/11000R

Abstract:

A speed reduction system for decreasing the speed of a moving craft has a craft engaging device, a control mechanism, and a hydraulic energy transfer system adapted to transmit energy from the craft engaging device to the control mechanism. The control mechanism is adapted to actively control release of energy from the hydraulic energy transfer system during the decrease of the speed of the craft. A method of controlling the operation of a valve includes adjusting the valve during the operation of the valve after comparing a condition to a desired condition determined by a profile. A hydraulic valve has a valve member defining passages arranged to balance the force of the fluid pressure acting on the valve member and an actuator connected to the valve member. A valve control system includes a controller and a driver arranged with the controller. The position of the valve is adjusted during a predetermined cycle to control the operation of the valve.

Assignee:

Marotta Scientific Controls, Inc. - Montville NJ

International Classification:

B64D001/08

US Classification:

244137100

Abstract:

A pneumatically actuated ejection rack system for an aircraft includes a storage tank for storing a pressurized gas at or above a first pressure level and a pressure reducer positioned downstream from the storage tank. The pressure reducer is adapted to reduce the pressure level of the pressurized gas so as to receive the pressured gas at the first pressure level and discharge the pressurized gas at a second pressure level lower than the first pressure level, whereby the second pressure level is sufficient to operate a firing mechanism of the ejection rack system.

Appl. No.:

7/344297

Inventors:

Peter A. Tartaglia - Butler NJ
Richard B. Collins - Denville NJ
Robert S. Smolen - Bloomingdale NJ

Assignee:

Marotta Scientific Controls, Inc. - Montville NJ

International Classification:

F16K 4714

US Classification:

1376253

Abstract:

The invention contemplates a valve construction which provides a radially stacked succession of mutually fitted concentric annuli fitted to an inner tubular member which is open at one end for accommodating inlet fluid flow and which is adapted along its bore and at the opposite end to guide a poppet member that is axially positionable in the bore. The tubular member has a circumferentially and axially distributed plurality of like radial passages adapted to be opened and closed in accordance with the guided position of the poppet member. Progressively increasing pluralities of such radial passages characterize each successive annulus, and all annuli are circumferentially channeled to define a manifolded relation between the plural passage discharges from one annulus and the plural passage inlets of the next annulus. Outlet or downstream flow from the valve is taken from a circumferential manifold around the outermost multiple-ported annulus. All of the plural passages are configured as diffusers, with expanding section in the radially outward direction.

International Classification:

F16K 4708
F15D 100

US Classification:

1376253

Abstract:

The invention provides a two-part casing for a multistage valve, itself configured for noise-reduction. Further noise reduction is achieved by complaint suspension of the valve in a two-part casing wherein separable parts of the casing define a cavity for containing nested stages of the valve. Provision is made for selective adjustment of compressional loading of the compliant suspension.

International Classification:

F16K31/12

US Classification:

137503

Abstract:

A system for controlling fluid flow to an approximate constant rate is disclosed. The system includes a housing, a flow control element, a cutout formed in the flow control element, a valve element, and a spring. The housing has an inlet opening and an outlet opening. The ends are arranged and configured to receive piping. The flow control element is operatively positioned within the housing with the flow control element having an upstream end and a downstream end with a cutout formed therein. The fluid flows in the inlet and through the cutout into a larger chamber within the housing before exiting the outlet end of the housing in normal flow. A valve element is disposed within the housing adjacent and upstream of the flow control element. The valve element is positioned within the housing by a spring means which urges the valve element toward the outlet. The valve element is operatively connected to a plunger member and moves relative to the flow control element according to the pressure differential between the inlet and the outlet.

Assignee:

Marotta Scientific Controls, Inc. - Montville NJ

International Classification:

F16K 1706

US Classification:

137471

Abstract:

The invention contemplates an improved poppet-type relief-valve construction which features an inlet-port configuration at upstream offset from the valve-closed seat region of the valve. To open the valve, a valve member must be moved by upstream pressure exceeding a predetermined threshold. This valve member integrally carries a specially profiled formation that (a) is upstream from the seat region and (b) coacts with a specially profiled region of inlet port. This action necessarily takes place upstream from the seat region and is such as to provide control of valve operation especially during that fraction of valve-member displacement that spans the "cracking" phase of valve operation. The net result is to avoid development of the "chatter" which customarily characterizes the "cracking" phase of valve operation.

Abstract:

A cap assembly for a threaded neck of a container includes an inner threaded cap which fits closely within an outer cap that is rotatable about the inner cap within defined limits. The outer cap includes a transparent window through which means are displayed to provide a positive indication of a prior usage or tampering. In one embodiment, a drive bar and a series of breakable fins on the outer cap seen through the window are moved into contact with a break and open bar on the inner cap. After the fins are broken, the drive bar engages the break and open bar to permit rotation of the inner cap with the outer cap and removal of the assembly to open the container. Replacement in the opposite direction causes the drive bar to engage a close bar on the inner cap to reseal the container while the broken fins remain visible. A second embodiment has an indicator sleeve instead of fins with a second drive bar to move a SAFE indicia in view of the window during the opening rotation. When the cap is replaced and tightened, a warning symbol moves into view to indicate the prior opening.
