US Patent:

56717695, Sep 30, 1997

Filed:

Oct 27, 1995

Appl. No.:

8/548977

Inventors:

Walter Booth - East Hanover NJ
Alan R. Levin - Somerville NJ

Assignee:

H-Tech, Inc. - Wilmington DE

International Classification:

F16K 1503

US Classification:

137 15

Abstract:

A swing check valve, which is adapted for automatically inhibiting back flow of fluid from an outlet thereof to an inlet thereof, includes a clapper member and a housing. The housing has a first body portion, which includes its own valve seat and its own mounting mechanism adapted to removably mount the clapper member therefrom when the first body portion is positioned adjacent to the inlet of the valve. The housing also has a second body portion, which includes its own valve seat and its own mounting mechanism adapted to removably mount the clapper member therefrom when the second body portion is positioned adjacent to the inlet of the valve. The first and second body portions are removably connected to each other in an end-to-end fashion and are interchangeable with each other, whereby each body portion may be utilized as a replacement for the other body portion.

Inventors:

Walter Booth - East Hanover NJ
Alan R. Levin - Somerville NJ

Assignee:

H-Tech, Inc. - Wilmington DE

International Classification:

F16K 4704
F16K 512

US Classification:

137 1

Abstract:

A device for controlling fluid flow through a conduit includes a ball valve with a ball having a conduit terminating at an end thereof in an outlet orifice having a non-circular shape. The orifice shape is compound and may be selected to linearize the flow/ball angle relationship. The ball may be reversible to permit reversing the flow change dynamic and may also be a flow reducer.

Filed:

May 31, 1995

Appl. No.:

8/455321

Inventors:

Walter Booth - East Hanover NJ
Alan R. Levin - Somerville NJ

Assignee:

H-Tech, Inc. - Wilmington DE

International Classification:

F16K 3700

US Classification:

137556

Abstract:

An actuator for actuating a valve from a first position to a second position includes a housing and a rotatable stem mounted within the housing and restricted from moving axially. The actuator also includes a non-rotatable plunger engaging the stem such that the plunger moves axially in response to rotation of the stem, whereby the valve is actuated from the first position to the second position. The actuator is also provided with a non-rotatable indicator member, which is mounted within the housing and through which the stem extends. The indicator member engages the stem such that the indicator member moves axially in response to rotation of the stem. A viewing window is formed in a wall of the housing such that the indicator member can be seen through the window for indicating the first position and the second position of the valve.

US Classification:

371 26

Abstract:

This disclosure is concerned with a novel method and apparatus peripherally and interactively used with automatic fault detecting computer systems and the like, wherein external control is provided for introducing intelligence into the probing of circuit board nodes and the like where insights into predictable or likely failures are available and the over-riding or discontinuing of normal computer-guided time-consuming back-tracking probing is thus desirable.
