Abstract: Provided are a method and system for using fluid to position a device in a socket for testing. The device is positioned within a socket and a body is coupled to the socket. Fluid is delivered to a chamber defined in part by the body, a first surface of the device to provide pressure onto the device to move the device within the socket.

Abstract: A method for determining the diameter of a wellbore, the wellbore being drilled by a drill string immersed in weighted mud, the weighted mud having a significant weight fraction of a heavy component. A well logging instrument having a gamma ray source and energy-sensitive gamma ray detectors rotates within the wellbore to define a transient interface with a facing portion of the wellbore wall. The instrument measures Compton-effect gamma ray scattering and photoelectric-effect gamma ray scattering of gamma rays that cross a first interface, and of later gamma rays that cross an opposite interface, at each of a plurality of locations along the wellbore to produce a group of gamma ray counts at each of a series of wellbore locations. The counts are used to determine standoffs, weight fraction, and wellbore diameter.

Abstract: A device is described for masking the gold connector tabs located along the edges of printed circuit boards to prevent the connectors from becoming solder coated during wave solder operations. The device is comprised of a pair of angle sections coupled to each other by tensioning means. The sections are easily applied to the circuit board assembly without scratching the gold contacts. Moreover, they provide stiffness to the board and a dam to prevent solder from flowing over the board and damaging the electrical components mounted thereon during wave soldering. The device is easily removable from the circuit boards after soldering and is reusable. Finally, the device of the present invention is characterized by long life, reasonable cost and ease of use.
