Abstract: A method of calibrating once-around and harmonic errors of encoded nips is provided. An encoder with an index pulse is used to measure the velocity and rotation of the driven wheel or idler. The geometry of the drive train and wheel and idler is chosen so that their once around and harmonic frequencies are unique such that no other drive errors will generate these frequencies. The method includes running the idler or wheel at substantially constant velocity for N revolutions. Each index triggers the collection of velocity data, which is averaged for N revolutions. This process detects drive train motion errors that are periodic with respect to the timing of the index pulse (i.e., once per revolution of the wheel or idler). Once the velocity errors have been measured, corrections are made. This method may be incorporated in xerographic machines as part of a setup or calibration procedure.

Abstract: A wireline cable length measuring apparatus tracks the length and other parameters of a wireline cable in a well bore. The apparatus has three major components: a rotational distance measuring assembly; a rotation-to-length (rotation:length) calibration assembly; and a processor unit. The rotational distance measuring assembly engages the wireline cable in a manner similar to a standard wireline count wheel, typically receiving the cable from a draw works or a wireline service truck. The rotational distance measuring assembly has a rotation sensor which generates a rotation signal in response to the paying-out and reeling-in of the cable over the count wheel. The rotation:length calibration assembly also engages the wireline cable. However, the rotation:length calibration assembly only intermittently engages the wireline cable, and therefore is subject to substantially less wear than the counter wheel.

Abstract: A method and apparatus for detecting magnetic marks on a wireline logging cable and for more accurately making depth measurements during logging is described. The method uses depth-based, rather than time-based, samples and calculations. A Hall Effect sensor samples the cable at regular depth intervals approximated by an encoder mechanism. The signal values from the Hall Effect sensor are signal processed to better discriminate the precise location of the magnetic marks on the cable. The location of the magnetic marks is used to refine the depth measurements from the encoder mechanism. Depth-based sampling eliminates detection dependence on cable speed, enhances detection ability, reduces computational load, and leads to more accurate determination of the location of magnetic marks.

Abstract: A length measuring apparatus for accurately measuring the length of a communication cable or other elongated object in the moving state and a method for the same. The preferable length measuring apparatus is a combination of a marking system and encoder system. The marking system counts the number of times a cable (1) moves by a standard length measurement distance (S) using that standard length measurement distance as one unit. To detect the conveyance of the cable by standard length measurement distances, a marker (43) makes marks (44) on the cable surface and the marks are detected by a laser switch or other sensor (46). The fine differences in distance between the standard length measurement distance and the mark interval (MS), that is, the surplus lengths (C.sub.1), are detected from the value of an encoder at the timing of detection of the marks.

Abstract: A depth measuring system for a slickline utilized in a well bore operation where the slickline is in a non-slip relationship with the circumference of a calibrated measuring wheel and the revolutions of the wheel are utilized to provide a first length measurement. A load cell is provided to measure tension in the slickline so that length elongation of the slickline due to tension can be determined. A temperature differential determination is made so that corrections in length can be made for the temperature effects. The temperature differential can be temperature effects on the measuring wheel and/or temperature effects of the slickline in the well bore. The measuring wheel determination of length is algebraically summed with the tension elongation and changes due to temperature to provide a more accurate indication of the depth measurement in the well bore.

Abstract: Apparatus is provided for the lineal measurement of continuous or stranded materials, such as cloth, otherwise transported past such apparatus. A gravity operated contact wheel is used to bias the materials into engagement with a measuring wheel, the rotation of which generates incremental distance pulses which are summed in a counter. An electric eye is used to detect the presence of materials to be measured so that a measurement count is held as a trailing edge of such materials departs from between the measuring roll and contact roll. The entire device may be supported on a support base which is in turn adapted to fit into a preformed opening or slot in the top surface of a work area such as a cloth cutting table. In such instance, the measuring device operates to measure cloth drawn across the table and in between the measuring and contact rolls.

Abstract: The method and the apparatus for the performance of the method for feeding cable into an automatic cable-processing machine allows to move normal cables (18) and cables of reduced wall thickness at high speeds. The cable (18) is driven by the driving surfaces (3.1, 8.1) of two belts, (3, 8), where the belts (3. 8) of two belt drives (b 1.2), roll off one another. The first belt drive (1) is stationary, while the second belt drive (2) is arranged to be parallel displaceable and disposed perpendicular to its driving surface (8.1). The second belt drive (2) can be pressed onto a laid-in cable (18) by at least one pneumatic piston-cylinder unit (24). In order to assure a clean passage of a cable (18) through the belt drives (1, 2), a cable clamping and tightening device (19) is arranged on the cable feed side (16), and a cable-clamping device (20) is arranged on the cable exit side (17). Thereby, the laid-in cable (18 ) is tightened and precisely aligned before the start of operations. The driving surface (8.

Abstract: A linear measuring apparatus for measuring elongated materials such as cables is disclosed. The apparatus includes a measuring station which includes two endless belts which run over two pulleys and between which the material to be measured is drawn. The measuring station is provided with sensors to which a counter unit is connected for indication of material lengths, and the endless belts (5a, 5b) extend horizontally, side-by-side, and resiliently abut the material to be measured.

Abstract: Apparatus (10) comprising rotatable feed belts (16,18) driven by a reversible electric servo-motor (20) which is operated by a pre-programmed electronic controller (30) feeds accurately measured lengths of a wire strand (12), regardless of wire slippage which may occur relative to the feed belts. Controller (30) receives feedback signals from an encoder (22) indicative of the distance and direction wire (12) actually moves, compares the feedback signal with stored data and recognizes the amount and direction of any wire slippage. Wire movement less (or more) than the desired length results in forward (or reverse) operation of servo-motor (20) and feed belts (16,18) to move the wire forward (or in reverse) until the desired length is reached. Encoder (22) is operated by a measuring wheel (24) which engages and is rotated by wire strand (12) itself during forward or reverse movement. Either "run-out" of wire strand (12) or too large a "following error" shuts down the apparatus.
