Abstract: The present invention provides device system and a method for monitoring movements of mining conveyances in a mine shaft. One or more sensors that form part of the system may be installed directly on the mining conveyances. The sensors may be accelerometers and are for detecting movements on mining conveyances. The system may analyze the descent and ascent paths of the mining conveyances on guides by recording vertical, horizontal and transverse accelerations. The analysis may comprise associating the movements with position of the mining conveyances on the guides for identification of an anomaly at a specific position.

Abstract: The invention relates to a device (1) for measuring the width (B) and/or the position of a metal strip (2) or a slab, which has at least two measuring systems (3, 4), with each located on a side (5, 6) of the metal strip (2) or the slab, wherein each measuring system (3, 4) has a sensor (7) designed to detect the lateral end (8, 9) of the metal strip (2). To make the measuring device robust and to enable dynamic measurement, according to the invention the sensor (7) is located on a moving element (10) with which it can be moved in a straight line in a direction (Q) at right angles to the longitudinal direction (L) of the metal strip (2).

Abstract: In one embodiment, the present invention includes a sensor having a roller adapted on a shaft to roll along a workpiece surface, a compliant member adapted around at least a portion of the roller, and an encoder to code information regarding movement of the roller. In some implementations, the encoder may be in communication with a processor of a machine to provide information regarding workpiece movement.

Abstract: A displacement measuring device includes a body which is movable on a plurality of rails and driven by a first shaft. An extension portion is connected to the body and a second shaft connected to the body extends through the extension portion. A first gear and a second gear are respectively mounted to the first shaft and the second shaft. Both of the two gears are engaged with a rack. A spring is received in the extension portion and pushes the second gear so that the second gear is pushed toward the rack. The second gear is snugly engaged with the rack so that the tolerance therebetween is reduced. A counting member is connected to the second shaft so that the number of the revolution of the second gear is counted and the sum of the displacement of the object can be precisely calculated.

Abstract: Calipering the thickness of individual books during production, independent of caliper bounce due to elastic resiliency of the books. A caliper roller is held apart from an anvil roller while a book is positioned between the two rollers. The caliper roller then is moved toward the anvil roller with sufficient resilient force to cause an initial maximum compression of the book between the caliper elements, followed by rebound movement of the caliper roller. The initial movement of the caliper roller is coupled to a measuring element through a lost-motion connection, so that the measuring element is not affected by rebound movement of the caliper roller. Movement of the measuring element thus corresponds to the initial maximum compression of the book by the caliper roller, which in turn corresponds to the actual thickness of that book.

Abstract: The hand-held apparatus of the present invention includes an integral printer and measuring device so that measurement information obtained from the measuring device may be automatically printed, used to determine additional information to be printed such as price information, or merely displayed. A measuring wheel having detectable marks disposed about the periphery thereof is rotatably mounted on the housing of the apparatus in proximity to a sensor that detects the marks. This sensor is positioned on the housing to not only detect the marks on the measuring wheel but to also detect the presence or absence of a label dispensed from the housing so as to provide an on-demand printing mode of operation. A controller is responsive to the sensor in the on-demand mode of operation for controlling a printhead to print on a supply when the previously printed supply has been removed from the apparatus.

Abstract: An apparatus and method for monitoring the condition at or near the surface of objects is disclosed. The apparatus is a vehicle which includes a housing which is supported and translated across the object surface by three wheels. The front or first wheel is associated with an encoder and sensor which magnetically determines the physical condition of the object. The apparatus includes a starter block which includes a series of metallic wires embedded at certain depths and locations within the starter block. The vehicle passes over the starter block prior to passing over the object in order that the vehicle be recalibrated by the starter block prior to observing the physical condition of the object.

Abstract: A device for measuring the movement of a drill pipe string, the end of which is held during drilling by an attachment assembly (12) movably along at least one guide rail (16), comprises a sensor assembly (38) mounted on the attachment assembly with a roller (42) designed to run on the rail as the attachment assembly moves.

Abstract: The edge to edge width of a moving workpiece is measured as the workpiece is transferred over horizontal table rolls between a pair of spaced apart generally horizontal sideguards extending perpendicularly of the axes of the table rolls. A pair of opposed arms have generally vertical central portions with the upper ends of the arms rotatably mounted to the sideguards about horizontal axes which extend in lengthwise vertical planes along the sideguards. The arms rotate in transverse vertical planes extending between the table rolls and transverse to the direction in which the workpiece moves. Contact rollers adapted to contact the opposed edges of the workpiece are supported at the lower ends of the rotatably mounted arms such that each contact roller contacts a workpiece edge in a transverse vertical plane within about 25.degree. of a lengthwise vertical plane when the center of gravity of the arm and contact roller structure is within about 20.degree. of the lengthwise vertical plane.

Abstract: A wheeled measuring device having selectively usable and positionable hub elements for use with a plurality of different measuring wheels and corresponding gearing for utilization of a counter to provide different readouts in effecting desired measurements. The hub elements are received in a recess in the housing of the measuring device and retained therein as a result of securing together of separate portions of the housing of the measuring device in the manufacture thereof.
