  • Patent number: 7266906
    Abstract: A measuring tool has a slider (3) supported to a body frame (1) and a feeding mechanism (4) for moving the slider in axial direction. The feeding mechanism includes: an outer roller (41) rotatably supported to the body frame (1); a forward feed roller (42) disposed between the outer roller (41) and the slider (3) at a position closer to a forward side of the slider (3) relative to the outer roller (41); a reverse feed roller (43) disposed at a position on a reverse side; a roller holder (45) supporting these feed rollers to allow them to move along the circumference around the axis of the outer roller; a first leaf spring (44) that biases these feed rollers toward the slider side; and a power transmitter (46) connecting the outer roller (41) to these feed rollers to transmit the rotation of the outer roller to the feed rollers.

  • Patent number: 6879653
    Abstract: The diameter of a segment of a peripheral rod in a fuel assembly is measured between two successive spacer grids. A measuring tool is positioned at a level situated between the two successive spacer grids, the tool comprising two measuring fingers that are free to move relative to each other in a first horizontal direction and that are urged towards each other by a resilient return arrangement, and that extend in a second horizontal direction perpendicular to the first horizontal direction. The measuring fingers are moved in the second horizontal direction towards a rod so as to put two contact pieces of the measuring fingers into contact with two zones of the rod segment. The measuring fingers are moved in the vertical axial direction of the rod along its segment situated between the two spacer grids and an electromagnetic sensor is used to measure the distance between the measuring fingers in the first horizontal direction while the measuring fingers are being moved axially.

  • Patent number: 6671976
    Abstract: An output-attached measuring instrument has: a measuring instrument body (1) having a circuit board (14) for processing a measurement signal from a sensor as a measurement data, an output electrode (15) for outputting the measurement data, and a connector hole (17) in communication with the output electrode and opening to an outer surface; and a connection cable (30) having a connector (32) capable of attaching to and detaching from the connector hole on an end thereof for transmitting the measurement data obtained by the measuring instrument body to an external device, the connector having a projection (33) capable of being plugged to and unplugged from the connector hole and a connector terminal (34) exposed on a surface thereof, where an elastic connector (20) having am electro-conductive portion for electrically connecting the connector terminal and the output electrode is accommodated in a space of the connector hole of the measuring instrument body and the elastic connector shuts the connector hole when

  • Patent number: 6073360
    Abstract: A mount for mounting a measuring instrument, such as an electronic measuring transducer. The mount includes a spring operated clamp assembly for attaching the mount to a first part with a reference surface engaging a desired location on the first part. In one embodiment, the clamp assembly grips the first part between a clamp member and a clamp portion. The mount has an unclamping member which may be operated with one hand to selectively open the clamp. In another embodiment, the clamp assembly includes a first clamp member and a second clamp member urged by a spring relatively away from the first clamp member, each of the first and second clamp members having a grip by which the first and second clamp members may be urged together then selectively released to clamp the mount in a gap between the first part and a second part.

  • Patent number: 5430954
    Abstract: There is disclosed a calliper, useful for measuring how much fat can be pinched beneath the skin, having jaws (4,6) pivotally mounted for relative pivotal movement. The movement is amplified by a gear train (24, 26, 28, and 30). The final gear wheel (30) drives a toothed wheel the movement of which is sensed by an opto sensor (34). A digital readout indicates the spacing between the jaws for indicating the spacing between measuring surfaces of the jaws. In contrast to conventional callipers, which are used only to transfer a dimension from an object to be measured to a measuring device, the callipers disclosed give a direct reading of the spacing between the measuring surfaces.

  • Patent number: 5174030
    Abstract: An apparatus for measuring the length or perimeter of an object has a main housing part provided with a main abutment and forming a main attachment location and a movable housing part provided with a movable abutment normally spaced longitudinally from the main abutment and with a movable location forming a guide. The movable part is longitudinally displaceable on the main housing part so as to displace the abutments longitudinally relative to each other and also to displace the locations longitudinally relative to each other. A flexible but substantially inextensible element has an outer end fixed to the main attachment location and an outer portion extending between the locations, passes through the guide at the movable location, has an intermediate portion guided in the movable part, and has an inner portion extending in the main portion and an inner end.

  • Patent number: 5070622
    Abstract: To measure the gaps between fuel rods in a fuel assembly, a feeler gauge is provided with a pair of resilient arms having elongated electrical resistance strips carried by their confronting surfaces and extending from terminations adjacent the free ends of the arms through a contact point of electrical inter-engagement. The strip terminations are wired into a metering circuit including a current source and an ammeter. When the arm free ends are positioned in a rod gap, the position of the contact point relative to the strip terminations determines the magnitude of resistance included in the metering circuit, and the meter registers the gap dimension.

  • Patent number: 4993170
    Abstract: A novel micrometer apparatus is provided which is capable of providing strip workpiece thickness measurements with high precision and without operator dependence, the apparatus including a fixed anvil mounted to a "C" frame, a movable shaft mounted opposite the fixed anvil at a separation distance from the fixed anvil which represents the thickness of material therebetween, the fixed anvil being held in position by the full weight of the apparatus and the center of gravity of the apparatus passes through the fixed anvil and solidly against the top surface of the essentially horizontal strip being measured, an indicator having a measuring head for carrying the movable shaft which contacts the bottom side of the strip opposite the fixed anvil, and a display head positioned atop the micrometer apparatus above the strip such that the thickness measurement is performed and displayed automatically while the apparatus sits unattended on the workpiece.

  • Patent number: 4989329
    Abstract: A rotary displacement transducer comprises a shaft rotatably supported in a housing, and to which the rotary displacement to be sensed is applied. The shaft is axially fixed in the housing, and has a precision screw thread formed over part of its length. An internally threaded sleeve coaxially surrounds the shaft in threaded engagement with the precision screw thread, the sleeve carrying a collar having two diametrically opposed radial projections. The first projection carries a roller which engages in a slot in the housing to prevent the collar and sleeve rotating as the shaft is rotated, so that rotation of the shaft causes the sleeve and collar to move axially of the shaft by an amount dependent on the rotary displacement to be sensed. The axial movement of the collar is sensed by a linear displacement transducer of the LVDT type coupled to the other radial projection on the collar.
