Abstract:
A method and system for detecting or measuring defects in a rope having ferromagnetic tension members includes a magnetic field exciter and an array of magnetic flux sensors corresponding to the tension members in a known relationship. Measurements of magnetic flux leakage are indicative of defects. Another aspect of the invention includes a method and system for detecting or measuring defects in an elevator rope having electrically conductive tension members, whereby measured electrical resistance in the tension members is indicative of defects.
Abstract:
The present invention relates to an apparatus for generating an electric signal corresponding to a force exercised thereon, e.g. a force arising out of the tension in a thread, preferably the tension in a thread in a loom or sewing machine, a mechanically bendable, tongue-like plate (1) being positioned in the path of the thread (14) in order to be bent by the thread (14) in correspondence to the force exercised in the thread, and at least one film resistor (R1, R2) being disposed on the plate (1) and being coupled into an electronic circuit for generating a signal corresponding to the mechanical action of the plate (1) to which the film resistor (R1, R2) is subjected on bending of the plate (1), and the path of the thread (14) past the plate (1) being substantially constant.
Abstract:
A monitoring system measures the tensile load on a ship's rode (the cable, chain or rope connecting the ship to its anchor) with a rode load sensor (22) and also measures the velocity and direction of the wind and the velocity of the current that produces the rode load with individual sensors (24, 25, 23). From those measured values, the system (20) calculates wind and current resistance factors enabling it to model rode load as a function of wind and current velocity. When the behavior of the monitored rode load departs from the behavior predicted by the model in a manner that is symptomatic of a catastrophic or dragging anchor system failure, the anchor monitoring system signals an alarm (32, 34). An alarm (35) is also produced if the rode load approaches the tensile strength of the rode. The system (20) also tests the anchor holding strength of the sea bed and provides anchor load information helpful to a skipper when motoring into the wind. The monitoring system senses rode load by using a load cell to laterally deflect the rode. The load cell includes a strain gauge generating an output signal that may be processed to determine the rode's, or any other lining like moring lines, running rigging, etc., tensile load.
