Abstract: An alignment tool that is used to hold a pipe fitting stationary in the welding process includes a pipe guide, a guide shaft, and an adapter. The adapter can vary according to the fitting that is to be welded. As an example, the adapter can be a flange adapter, a 90-degree adapter or a 45-degree adapter. The guide shaft is slidably engaged to a connecting arm which is perpendicularly and terminally fixed to the pipe guide. Therefore, the distance between the guide shaft and the pipe guide can be varied as preferred. A base section of the adapter is slidably engaged along the guide shaft. Therefore, the position of the fitting which is mounted on the adapter can also be repositioned as preferred. In order to hold the pipe against the pipe guide, a chain is being used.

Abstract: Disclosed is a pit cover and method of installing the same. The pit cover includes a plate having a hole defining an area. A block having a threaded hole may be affixed to a bottom surface of the plate such that the threaded hole aligns with the area. A support is associated with the foundation and a groove is defined by one of the pit cover or the support. A protrusion is defined by the other one of the pit cover or the support. The groove narrows from a first width towards a second width. The first width is disposed relative to the second width such that insertion of the protrusion into the groove causes an end of the protrusion to pass the first width prior to passing the second width. The protrusion interacts with the groove to align the pit cover at a predetermined position relative to the foundation.

Abstract: A tool to aid with pulling a closing loop cord through grommets in closing flaps on a parachute container. The cord is looped in a “U” shaped arrangement with two pulling “legs” of equal length being wrapped around a handle to provide a better grip. Only one leg of the cord can be permanently attached to the handle as the other leg must be removable for fishing through the grommets. The handle must have a diameter to permit passage through the eye of the grommet with the two legs of the cord trailing behind. With existing handles, the removable end of the cord slides off the end of the handle when passing through the grommet. An “O” ring placed on one or both ends of a radial groove in the handle holds the cord captive when passing the handle through the grommets to prevent the cord from sliding off.
