Filed:

Jul 20, 2005

Appl. No.:

11/185492

Inventors:

Douglas F. Fuller - Grand Prairie TX, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

H01J 3/14
G01J 3/50
G02B 5/22
F21V 9/00

US Classification:

250216, 250226, 359885, 252582

Abstract:

A plasma absorption wave limiter is disclosed. The plasma absorption wave limiter comprises a limiting layer and a trigger layer. The limiting layer is transmissive in a pass band of a sensor and capable of generating a reflective and absorptive free electron plasma that will propagate and dissipate therein. The trigger layer is located aft of and in contact with the limiting layer and is capable of residually absorbing incident radiation and initiating the thermal plasma wave in the limiting layer responsive to a threat.

International Classification:

E05F 1100

US Classification:

160191

Abstract:

A counterbalance mechanism for a sectional garage door includes an elongated shaft mounted above the door opening and supporting spaced apart cable drums connected to respective cables which are connected at one end to the door for exerting a counterbalance force thereon. Opposed torsion springs are connected to the cable drums at one end, respectively, and to respective hub members which are axially slidable on but nonrotatable with respect to the shaft. The cable drums are provided with detachable bushing members for engagement with the support brackets. The shaft is connected to a non-reversible worm gear drive at one end. The worm gear drive may be actuated to selectively vary the torsional deflection of the counterbalance springs by rotating the worm and a ring gear meshed therewith. The worm gear drive may be detachably mounted on one or the other of shaft support brackets and a lock plate is supported on the shaft and engageable with a bracket to prevent rotation of the shaft when the drive mechanism is removed. The door guide members are engaged with coil compression springs for centering the door between its guide tracks and to minimize skewing of the door during opening and closing movement.

Assignee:

Overhead Door Corporation - Dallas TX

International Classification:

A47G 502

US Classification:

160265

Abstract:

A flexible roll-up door assembly includes opposed, elongated frame members supporting guides for longitudinal side edges of the door and for slide members connectable to a bottom beam of the door closure member by a latch mechanism which includes opposed latch members which engage the slide members, respectively. The slide members rotate to permit the latch members to separate in response to a predetermined force acting on the door closure or the bottom beam. The latch members are spring biased to retract out of or extend into cooperating slots in the slide members and may be reinserted in the slide members to reconnect the door to the guides. The latch members may include retaining projections cooperable with reentrant edges or other surfaces in the slots to retain the latch members engaged with the slide members. Alternate embodiments include latch members formed on the slide members and engaged in slots formed in a transverse bottom beam for the door closure member. Spaced apart tensioning reels are mounted on the door closure shaft and support cables which are trained through the guides and are connected to the slide members to apply a pulldown tensioning force on the door closure member.

International Classification:

H01Q 1/12

Abstract:

The present disclosure describes a telecommunications structure including a plurality of mounting members each having a length and a diameter, the plurality of mounting members includes one or more vertically-oriented mounting members that intersect with one or more horizontally-oriented mounting members to form a frame that is configured to have telecommunications equipment mounted thereto. Each of the one or more vertically-oriented mounting members or each of the one or more horizontally-oriented mounting members includes a plurality of longitudinally spaced-apart recesses configured to receive an intersecting horizontally-oriented mounting member or vertically-oriented mounting member and form a mechanical connection therebetween. A press tool for forming the recesses and methods of using the same are also described herein.
