Abstract: A printed circuit board is aligned to its mounting plate by using cutouts already cut for electronic components. A top plate with a notched location block and two edge locators is placed on top of both the printed circuit board and the mounting plate so that the notched block straddles two cutouts on the board and the mounting plate. At the same time, the two edge locators are placed inside the two matching cutouts. An eccentric cam is used to move a pressure plate that slides on top of the top plate and pushes both the circuit board and the mounting plate with spring action. The cam is turned until the edge locators hit the edges of the cutouts, aligning the printed circuit board to the mounting plate.

Abstract: A fluid-filled pipe is investigated by a non-intrusive procedure to determine whether the fluid is liquid or gaseous, whether it is flowing or static, the direction of flow if it is flowing, the approximate pressure if it is a gas, and the rate of flow if it is a gas. The results are obtained by applying a heater to the surface of the pipeline and measuring the upstream and downstream temperatures of the surface of the pipe wall before and after the beginning of the application of heat. Some of the data generated is compared with data from another source to assist in the determination of the characteristics to be ascertained.
