Superelastic Sealing Closures
US Patent:
6393765, May 28, 2002
Filed:
Aug 24, 2000
Appl. No.:
09/644658
Inventors:
David Goldstein - Potomac MD
Joseph P. Teter - Mt Airy MD
Joseph P. Teter - Mt Airy MD
Assignee:
The United States of America represented by the Secretary of the Navy - Washington DC
International Classification:
E06B 716
US Classification:
494751, 494891
Abstract:
A closure system including a rigid structural part has an edge surface along which sealage is established in response to deformation of a superelastic sheet metal element positioned thereon, such sheet metal element being endowed with a shape memory characteristic by formation as a Nitinol alloy to meet high sealage standards and other environmental requirements.
Non-Welded Shape Memory Alloy Rings Produced From Roll Flattened Wire
US Patent:
6780260, Aug 24, 2004
Filed:
Dec 10, 2002
Appl. No.:
10/318673
Inventors:
David Goldstein - Potomac MD
Steven S. Kim - Crofton MD
Steven S. Kim - Crofton MD
Assignee:
The United Sates of America as represented by the Secretary of the Navy - Washington DC
International Classification:
C22F 110
US Classification:
148563, 148676
Abstract:
A method for producing a non-welded shape memory alloy ring, such as Nitinol, includes a wire segment. The alloy ring may be used in a venting mechanism for rocket motors or as a coupling device, such as for fitting piping.
Long Rod Extension System Utilizing Shape Memory Alloy
US Patent:
5408932, Apr 25, 1995
Filed:
Sep 7, 1994
Appl. No.:
8/301505
Inventors:
Philip W. Hesse - Ellicott City MD
David Goldstein - Potomac MD
David Goldstein - Potomac MD
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
F42B 1202
US Classification:
102501
Abstract:
An elongated rod made of a shape memory alloy composition having selected eudoelastic properties, is deformed into a dimensionally compact coil for packaged storage under stress maintained by physical constraint. Upon selective removal of the constraint allowing shape recovery, a substantial increase in axial length of the rod occurs in order to improve its performance in various installations, including long rod penetrating projectiles.
Manufacture Of Nitinol Rings For Thermally Responsive Control Of Casing Latch
US Patent:
6240727, Jun 5, 2001
Filed:
Apr 27, 2000
Appl. No.:
9/559053
Inventors:
David Goldstein - Potomac MD
Peter Hall - Columbus OH
Peter Hall - Columbus OH
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
F01B 2910
US Classification:
60528
Abstract:
Axial sections of a casing assembly such as that of a rocket are maintained interconnected by latching prongs on which thermally responsive Nitinol rings are positioned. Operational control over the latching prongs is achieved by selection of material properties and dimensions of the Nitinol rings during manufacture thereof.
Shape Memory Actuator System
US Patent:
6041728, Mar 28, 2000
Filed:
Jul 31, 1998
Appl. No.:
9/126859
Inventors:
David Goldstein - Potomac MD
Thang Dinh Nguyen - McLean VA
Thang Dinh Nguyen - McLean VA
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
C22C 4300, B63G 814, B63H 2506
US Classification:
114162
Abstract:
A control tab on a submarine or the like is angularly displaced by a remote control actuator system featuring a pair of shape-memory cables consist of a superelastic actuating cable connected to the control tab and a force generating thermoelastic cable anchored to the submarine frame. A force transmitting lever interconnects the cables and is selectively locked by a releasable locking mechanism in a position holding the actuating cable fully stretched with the control tab displaced a maximum amount from its neutral position by the displacing force generated in the thermoelastic cable in response to heating thereof by electric current conducted therethrough.
Regulated Dispensing System
US Patent:
5685456, Nov 11, 1997
Filed:
May 24, 1995
Appl. No.:
8/449162
Inventors:
David Goldstein - Potomac MD
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
B65D 3528
US Classification:
222 95
Abstract:
A coil spring made of a shape memory alloy is seated within the container a portable dispenser in a contracted condition under compressive stress maintained by the physical constraint of a pressure plate engaging a collapsible enclosure internally lining the dispenser container to isolate therein material to be dispensed. The pseudoelastic properties of the shape memory alloy are selected to exclusively regulate the storage and delivery pressures in order to accommodate different materials to be dispensed and control discharge thereof by the dispenser.
Method Of Making Composite Structure Having A Porous Shape-Memory Component
US Patent:
5482574, Jan 9, 1996
Filed:
Oct 4, 1994
Appl. No.:
8/317451
Inventors:
David Goldstein - Potomac MD
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
C21D 1000, C22K 100
US Classification:
148517
Abstract:
A shape-memory alloy material is liquefied by heating for casting into sts that are coated with an adherent material and collected into a preshaped porous mass so as to assume a preshaped configuration and be restored thereto under selected temperature conditions. When installed into a composite structure, the preshaped porous mass endows the composite structure with the shape-memory properties of the strips.
