A system for controlling slack in a winch rope associated with a vehicle can include a winch, a plow, and a support member pivotably coupled to the plow and carrying a pulley that receives the rope for raising and lowering the plow. A limit switch can be operatively associated with the winch and configured to selectively enable and disable lowering of the plow by the winch. A first member can be carried by the support member and operatively associated with the switch. A biasing member can bias the support member to a first position when a load on the winch rope is below a predetermined threshold. The first member can be in at least substantial alignment with the switch when in the first position. The switch can change an activation state upon the first member being in the first position to automatically disable lowering of the plow by the winch.

A winch is employed for deploying a probe to a precise depth within a water column for making and recording physical measurement within such water column. More particularly, the winch rapidly unspools a line from an underway vessel, while maintaining minimal but constant line tension, as a probe, tethered to such line, descends within the water column in a “near” free-fall to a predetermined depth and then stops. The line lacks means for communicating its depth to the winch. The probe achieves a predictable descent behavior, even though it is tethered by a line to a winch onboard an underway vessel of unknown velocity and in variable weather conditions. The predictable descent behavior is achieved by maintaining a minimal constant tension on the line within a narrow range. The descent behavior of a probe in “near” free-fall has sufficient predictability to construct an algorithm to correlate descent time with depth. The predictability is sufficient to reduce the risk of collision between the probe and the water bottom to an acceptable level. 1.

A drum assembly and a method of laying a line (L) onto a drum (D) uses an oscillator device to apply vibrations to the line as it is being wound onto the drum. The oscillator device () sequentially increases and decreases the load on the rope as it is being wound onto the drum, causing differential fluctuations in the tension of the line as the line is diverted away in opposite directions from a straight line path to the drum. The vibrations typically cause a rapidly alternating load on the line, which is additional to any load applied to the line during laying of the line onto the drum. This alternating load typically reduces the available stretch in the line, and therefore assists in compaction of the line on the drum. 1. A drum assembly having a drum arranged to receive a line , wherein the assembly has an oscillator head comprising an oscillator device adapted to generate vibrations , wherein the oscillator head is adapted to engage the line and to apply vibrations generated by the oscillator device to the line as the line is being received onto the drum.2.

Tension monitoring arrangement and method

Номер: US20160146683A1
Автор: Albert W. Chau, Charles Yu Yat Tsang, John E. Mercer, Rudolf Zeller
Принадлежит: Merlin Technology Inc

Tension monitoring is described using a sensor which may exhibit an offset for which compensation may be provided to produce a zero voltage amplified output or to increase dynamic range. An arrangement determines whether a power reset is responsive to a battery bounce such that an initially-measured system start-up parameter can be retained. The start-up parameter is automatically saved at start-up if the power reset is responsive to a start-up from a shut-down condition. The start-up parameter may be a zero tension amplified output responsive to the sensor offset at zero tension. Protection of a tension data set is provided such that no opportunity for altering the data set is presented prior to transfer of the data set. A housing configuration forms part of an electrical power circuit for providing electrical power to an electronics package from a battery.
