Appl. No.:

10/299036

Inventors:

William Gilbert - Rio Vista TX, US
Corbin Glenn - Benbrook TX, US

International Classification:

F42D003/00
F42B003/00

US Classification:

102/312000

Abstract:

The invention uses a pair of opposed tabs on the charge holder to engage a groove in the case of the shape charge. The case is generally conical in shape. However, the front opening of the case has both a first and second circumferential ridge separated by a groove. The diameter of the groove generally matches the distance between tabs. The second ridge can have a flat milled thereon to allow case to be inserted until the tabs contact the forward or first ridge. This locates the tabs between the first and second ridges and over the groove. The case is then rotated so that the tabs are captured between the two ridges. Once installed, the detonation cord is attached to the case. The cord helps prevent any rotation of the case, thereby securing it into the charge holder. Thus, the use of easily milled tabs on the charge holder in conjunction with an easily milled groove and flats on the case provide an improved apparatus and method for securing the shape charge into the charge holder of a perforation gun. When the charges are all installed, and the detonation cord is properly linked between each charge, then the charge holder can be placed in a carrier.

International Classification:

E21B029/10

US Classification:

166/055000

Abstract:

A perforating gun assembly useful in hydrocarbon well completion. The gun is assembled in a carrier made from straight walled tubing as a primary structural member with complementary male and female threads cut into opposite ends so that gun assemblies may be directly connected together. The male coupling includes a reinforcing sleeve threaded into an internal thread. An alignment pin is positioned in the carrier extending through the reinforcing ring and into the interior of the carrier. A charge assembly includes a charge holder tube with upper and lower alignment fixtures. The lower alignment fixture includes an alignment slot for mating with the alignment pin and a shoulder for supporting the charge assembly on the sleeve. The upper alignment fixture has an alignment pin for mating with an alignment slot in the carrier. A retainer ring may be threaded into the upper female threads to prevent removal of the charge assembly from the carrier.

International Classification:

B64C 322

US Classification:

244123

Abstract:

An aircraft wing box construction including canted sheet metal spar webs continuously tied to the upper and lower skins. Sheet metal intercostal stiffeners of substantially triangular configuration are spaced spanwise along the web to provide shear stiffening for the web and intermittent stabilization for the upper skin. Both the shear web and intercostal stiffeners are fastened to spanwise continuous spar caps which are attached to the upper and lower skins. These caps, supported by the intercostals and webs, provide sufficient stabilization to prevent upper skin buckling up to ultimate design stress with a minimum of shear webs thereby providing significant weight savings.

Inventors:

William A. Gilbert - Fort Worth TX

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04M 100

US Classification:

379433

Abstract:

A flap housing (14) for a foldable radiotelephone handset (10) has a hinge pin (72) with an actuator (96) for the radiotelephone activation switch (44) and a detent catch (88) integrated with the flap housing body (60). The actuator (96) engages the switch (44) to deactivate the handset (10) when the flap housing (14) is in a closed position. The detent catch (88) engages a detent stop (110) on the front housing (30) of the radiotelephone (10) when the flap housing (14) is in an open position.
