Abstract: A portable computer including two plastic enclosures has a first hinge body attached to a first one of the enclosures. The first hinge body includes a bore formed therein. A flowable lubricant such as grease is disposed within the bore. A second hinge body is attached to a second one of the enclosures. The second hinge body includes an elongated shaft pivotally mounted within the bore having grooves formed on an outer surface of the shaft. A sealing member such as an O-ring is resiliently compressed between one of the grooves and an inner surface of the bore.

Abstract: Reliability of a multi-lug breech bolt is improved by modifying the bearing relationship between the bolt lugs and the matching lugs within a gun receiver. This procedure is applied to a gun that has a receiver housing a breech bolt and an extractor. The extractor is coupled to the breech bolt and configured to move relative thereto. The bolt for this gun has at least five radially extending bolt lugs configured for bearing contact with the receiver when positioned for firing. The bolt lugs include a first, second, and third bolt lug with the first and second bolt lugs being adjacent and defining a gap configured to receive the extractor therebetween. The third bolt lug extends from the bolt opposite the gap. Stress imparted to the first and second bolt lugs from firing the gun is reduced by altering the gun to prevent formation of a bearing relationship between the third bolt lug and the receiver when the bolt lugs are positioned for firing. The gun is reassembled as part of the procedure.

Abstract: The present invention is a receiver made by a welding process. The receiver made according to this process has less net distortion because of a number of techniques used in the process, including: (1) cooling the weld with Carbon Dioxide (CO.sub.2) preheated with the welding torch tip; (2) use of not more than approximately 4% oxygen in the shield gas to enable hotter, faster welding; (3) the use of a reduced voltage and wire feed rate at the end of a weld to avoid cracking; (4) the intentional use of distortion to reduce net distortion; and (5) sequencing of welds to reduce distortion. Distortion can be introduced in the stamped parts as they are made or when placed in a fixture for welding that, when welded, have less distortion than before. Distortion can also be countered by welding parts in a sequence where a subsequent weld reduces the distortion of a previous weld.

Abstract: A hinge and check assembly for checking the door of a motor vehicle when in the open position. The assembly provides a base having check profiles formed therein to establish predetermined check positions. The assembly also provides a strap that provides a spring biased contact surface for engaging the check profiles formed in the base. The strap is pivotally connected to the base through a pivot pin that defines a hinge axis, and the strap is allowed to rotate with the door of the vehicle about the hinge axis. Upon rotation of the strap, the contact surface follows the check profile and establishes a predetermined check position. The check profiles are perpendicular to the pivot pin, and the contact surfaces are perpendicular to the check profiles so that the check force applied to the pivot pin is in an axial direction. By having the check force applied axially to the pivot pin, deformation and wear to the pivot pin and its associated bushing does not occur.

When the pin is being extracted, the force is transferred through the slotted bar to the bottom of the head.

Abstract: The present invention is a method for welding difficult-to-weld metal components as illustrated in the welding of a receiver for a weapon. The method reduces net distortion by a number of techniques, including: (1) cooling the weld with Carbon Dioxide (CO.sub.2) preheated with the welding torch tip; (2) use of not more than approximately 4% oxygen in the shield gas to enable hotter, faster welding; (3) the use of a reduced voltage and wire feed rate at the end of a weld to avoid cracking; (4) the intentional use of distortion to reduce net distortion; and (5) sequencing of welds to reduce distortion. Distortion can be introduced in the stamped parts as they are made or when placed in a fixture for welding that, when welded, have less distortion than before. Distortion can also be countered by welding parts in a sequence where a subsequent weld reduces the distortion of a previous weld.
