Abstract: A sheet separation and feeding system for measuring substrate bending stiffness and thereby basis weight on a real time basis. Provided is a corrugator having a plurality of parallel ribs, with one or more sheets of the substrate provided below the corrugator wherein a predetermined gap exists between a topmost sheet of the sheets and the corrugator. A vacuum is applied between the corrugator and the topmost sheet, wherein the vacuum is sufficiently large to raise the topmost sheet, thereby deflecting and bending it into a profile corresponding to the arrangement and size of the corrugator ribs and bending stiffness of the substrate. One or more sensors are provided for measuring the deflection of the topmost sheet. The vacuum, an air knife output and/or a fluffer output are then adjusted according to predetermined rules and the measured deflection.

Abstract: A wire tensioning apparatus and method tensions one or more wires by moving the tensioning function from a wire module to an apparatus external to the wire module. Within the wire module, the wire is placed between a movable member and a stationary member. Tension is placed on the wire and adjusted until the desired tension and/or vibrational frequency is met. Once the desired tension and/or vibrational frequency is met, the wire is clamped between the movable and stationary members within the wire module in order to maintain the achieved tension and/or vibrational frequency.

Abstract: A wire tensioning apparatus and method tensions one or more wires by moving the tensioning function from a wire module to an apparatus external to the wire module. Externally to the wire module, a wire is attached to a fixed end and a movable end. Tension is placed on the wire, and the tension in the wire or the vibrational frequency of the wire is detected and compared to a desired value. If the tension in, or the vibrational frequency of, the tensioned wire does not correspond to the desired value, the tension is further adjusted until the desired value is met. Once the desired tension or the vibrational frequency is met, the wire is secured in the wire module in order to maintain the achieved tension and/or vibrational frequency.

Abstract: An accelerometer properly positioned in conjunction with an energized electrical conductor produces an output that is dependent on conductor's inclination angle in real time where the inclination angle is then used to calculate the sag of the conductor. A transmitter is used to communicate this information in real time to a central location such that up to optimal or maximum power transmission is feasible through the conductor while maintaining safe clearance from the ground. This allows for close monitoring of thermal expansion resulting from increased load as well as varying environmental conditions.

Abstract: The stickiness of cotton is determined by testing a cotton sample at two or more temperatures. Sticky deposits are recorded at a lower temperature, preferably 27° C. or 34° C., to detect the trehalulose-rich honeydews droplets. Then, the sample is subjected to a higher temperature, preferably 54° C., to detect the non trehalulose-rich honeydew droplets and physiological sugars. By comparing the results at these two temperatures, an accurate grading system for cotton may be produced which can help growers and spinners accurately identify different types of cotton and determine processing problems.

Abstract: An apparatus and method for biaxial load deformation testing of textile and other membrane materials including a first pair of spaced-apart segmented clamping systems for detachably engaging a membrane test material along opposing sides in the X direction. A second pair of spaced-apart segmented clamping systems is provided for detachably engaging a membrane test material along opposing sides extending in the Y direction. Each of the first pair and each of the second pair of spaced-apart segmented clamping systems are interconnected by a pantograph so as to be slidably extendable and slidably contractible with respect to each other and proportional to strain in the membrane test material in the X and Y directions, respectively. The first and second pair of segmented clamping systems are interconnected by a linkage system such that the second pair of segmented clamping systems will slidably extend in the Y direction proportional to strain imparted to a membrane test material in the Y direction when the first pair of segmented clamping systems is caused to move apart in the Y direction, and the first pair of segmented clamping systems will slidably extend in the X direction proportional to strain imparted to a test membrane in the X direction when the second pair of clamping systems is caused to move apart in the X direction.

Abstract: The device of the invention is intended for measuring a loading force and a friction force in a tribological tester. The device consists of two deformation-sensitive sensors for simultaneous equal deformation in two opposite directions for eliminating misbalance created in the measurement system when a single sensor is used. Each sensor is a deformable beam having through longitudinal slots extending in different and non-parallel directions and overlapped within the body of the beam. The sensor deforms in one direction under the effect of a loading force measured by two pairs of strain gauges located on opposite sides of the beam near one end of the beam and in another direction under the effect of a friction force measured by another two pairs of strain gauges located on opposite sides of the beam near the other end of the beam. Two sensors are sandwiched between two plates in a diagonally symmetrical positions so as to transmit forces between both plates and at the same time to ensure limited freedom of movement between both plates to allow deformations caused by the applied forces. One plate may be attached to the loading unit of the tester and another plate may support an upper sample for engagement with the lower sample of the tester.

Abstract: A method of monitoring on-line the initial modulus of a spun and at least partially drawn textile yarn is provided. The method consists of forwarding the yarn from a forwarding point to a package, winding the yarn on the package whilst traversing the yarn adjacent the package at a periodically disturbed speed, and continuously measuring the short term variation in yarn tension due to the change in yarn path length between the forwarding point and the package. An alarm is initiated if the sampled data is equals predetermined limits. The initial modulus of the yarn is calculated from the amplitude of the tension variations.
