Abstract: A tank is coupled to a body assembly of the fuselage of an aircraft with a lug of the tank mounted on a pin coupled to a body assembly. The pin is marked using a special tool with a first location mark and a second location mark. The lug of the tank may be mounted on the pin. To verify that the tank is correctly located on the pin, the position of the lug may be compared to two marks disposed on the pin. When the respective marks are visible on either side of the lug, the tank is properly aligned on the pin and the tank can be secured to the body assembly. The process is particularly helpful when the pin is located in an area that is inaccessible for direct observation or measurement after the tank is in place.

Abstract: A brake stroke logging indicator for determining brake stroke condition on a vehicle braking system comprising a moveable logger within a housing which logger can be moved within the housing from an initial position to a moved position, by the pressure from a brake pushrod. After the pressure from the brake pushrod has been released however, the logger remains in position in the housing. As such, the logger indicates the distance of the longest brake stroke traveled since the system was reset, without the need of a second person, or brake pedal jamming device. The indicating logger will always indicate the longest stroke traveled, where the driver has no need to hold the brake pedal down for inspection. Moreover, when the vehicle is stopped the indicating logger will indicate other mechanical problems that normally can be detected only when the vehicle is in motion.

Abstract: A special marker is disclosed that is affixed to a stationary or moving web near the lateral web edge to designate defective material. When edge trim is removed from the web, the trim removal device also cuts-off the front end of the marker so that the remaining portion is momentarily flush with the new web edge. This cutting action activates the remaining portion of the marker so that a component of the marker advances to extend out beyond the new web edge such that it is visible after the marker is wound into the rewind roll. This ability to see where the web was initially marked, after edge trim is removed, eliminates the conventional inaccurate and wasteful practice of remarking the web.

Abstract: Certain earthworking vehicles are often provided with the ability to change work implements to enable them to perform a variety of operations. In many instances, the coupling mechanism between the work implement and the frame structure of the vehicle that supports them is designed such that the implements may be mounted and removed quickly. During the mounting of the implement upon the support frame, there is no means by which an operator can be sure that the proper attachment has been achieved.

This indication can only be attained when the respective components are aligned in a manner that will allow a proper attachment.
