Filed:

Oct 18, 2000

Appl. No.:

09/691534

Inventors:

David M. Paquin - Cypress TX
Carl E. Davis - Houston TX
George Megason - Spring TX

Assignee:

Compaq Computer Corporation - Houston TX

International Classification:

H05K 500

US Classification:

361752, 361759, 361801, 24 4117

Abstract:

A system for facilitating the mounting of circuit boards within an enclosure. The system includes one or more standoffs that are each received through appropriately formed corresponding openings through a printed circuit board. A flexible clip is attached to the printed circuit board proximate each opening. Each clip includes a retainer portion designed to receive the head of the standoff. Thus, the printed circuit board may be attached to the standoffs simply by placing the circuit board openings over the standoffs and moving the printed circuit board laterally until the clips and standoffs are engaged.

Filed:

Dec 31, 1996

Appl. No.:

8/777819

Inventors:

Paily T. Varghese - Tomball TX
Robert J. Hastings - Humble TX
Carl E. Davis - Houston TX

Assignee:

Compaq Computer Corp. - Houston TX

International Classification:

G06F 116
H05K 502

US Classification:

361724

Abstract:

A modular computer chassis for both rack mounting and free standing use comprising a housing adapted for receipt of a plurality of computer modules in a secured array. The modules are selectively accessible only through a cover panel door which may be locked to secure the integrity of the array. The modules are mounted in the chassis on individual slides which afford alignment and stability in the assembly thereof. Additionally, the modularity affords interchangeability with rack-mounted systems for maximizing the efficiency of operation and the effectiveness of installation and service. Problems within the system can thus be addressed by removing and replacing individual modules in a configuration which affords reliability and easy access.

US Patent:

Filed:

Sep 11, 1978

Appl. No.:

5/941166

Inventors:

Carl A. Davis - Houston TX

International Classification:

E21B 3316

US Classification:

166291

Abstract:

An improved well shoe or collar has at least one tooth protruding from the top of the cement shoulder of the shoe or collar capable of engaging, denting and penetrating a pump down wipe plug and retarding the tendency of the plug to rotate when engaged by a drilling bit, thereby enhancing the drilling action of a drill bit on a pump down wipe plug. An improved process of cementing within a well and drilling through a plug comprises inserting a pump down wipe plug at the interface of a fluid and wet cement, pumping the plug down the well until it comes into contact with a shoulder of a shoe or collar having at least one protrusion extending from the surface of the shoulder capable of engaging, denting and penetrating the plug, subsequently after the cement has set, lowering a drill bit onto the top of the plug, the protrusion retarding the tendency of the plug to rotate with the rotating action of the drill bit and enhancing the drilling action of the bit.
