Abstract:

A line tensioner is disclosed. A winch has a winch drum with at least one groove over which a line is passed. The winch has a line tensioner assembly with a stationary cam surface and a plurality of line tensioners rotating with the winch drum. Each has a line gripping portion and a cam follower. The line gripping portion is brought into and out of contact with the line as the cam follower rides along at least a portion of the cam surface.

International Classification:

B66D 1/46

Abstract:

A winch drum is disclosed. In a first aspect, a first set of teeth are positioned around an outer perimeter of a drum. The first set of teeth taper from a first crown to a first base. A second set of teeth are positioned around the outer perimeter of the drum. The second set of teeth taper from a second crown to a second base. The second set of teeth are offset from the first set of teeth such that a gap between the first bases and the second bases forms a sinusoidal channel for a line to follow the first set of teeth and the second set of teeth becomes a guide for the line so that the line can engage the sinusoidal channel. The line follows the sinusoidal channel and each change of direction along the sinusoidal path causes the line to engage by friction with the first bases and the second bases. In a second aspect, the drum includes a trough that follows a sinusoidal path and wherein the trough is narrower at its bottom than at its top.

Abstract:

Systems and methods for disposing of blackwater are disclosed. A first vessel contains a screw running through the vessel from a first end to a second end. The screw is surrounded radially by a filter. The first vessel has a blackwater inlet adjacent the first end. An extrusion plate is adjacent the second end of the first vessel. A combustor vessel is configured to receive a solids component from the extrusion plate. A blackwater stream, consisting of a liquid component and the solids component, is passed through the blackwater inlet into the first vessel, is conveyed by the screw from the first end to the second end, and is pressurized against the extrusion plate. The liquid component is thereby forced from the blackwater stream through the filter and the solids component is forced through the extrusion plate into the combustor. The combustor is configured to combust the solids component.

Abstract:

Methods and systems for reducing an average particle size of blackwater solids is disclosed. A vessel is configured to receive a blackwater stream through a one-way inlet. The one-way inlet is configured to allow the blackwater stream into the vessel and prevent backflow. The blackwater stream contains blackwater solids and water. A device in a bottom portion of the vessel is configured to receive the blackwater and comminute the blackwater solids. A recirculating pump is configured to recirculate the blackwater stream under pressure through the device until the average particle size of the blackwater solids is reduced below a size threshold, resulting in a sized blackwater stream.

Nathan Davis - Bountiful UT, US

International Classification:

B66D 1/34

Abstract:

A device and method for retaining a line on a drum is disclosed. The drum has a slot which extends from a point along the periphery and into the drum in a first direction and at an acute angle relative to a tangent at the point. A clamp is provided with a slot portion and a line retaining portion. The slot portion is engaged with the slot such that relative movement between the clamp and the drum causes the slot portion to move in the first direction. As tension is applied to the line, a first force is created on the slot member in the first direction, resulting in a second force being applied by the line retaining portion in the first direction, clamping the portion of the line against the drum.

Abstract:

Devices, methods, and systems for a fairlead changing direction of a line under tensions are disclosed. The fairlead may include an opening with a front lip. The line under tension may be roved through the opening. The front lip may have a variable radius round. The front lip guides a change in direction of the line.

Abstract:

Devices, systems, and methods for separating solids from liquids are disclosed. A vessel includes an inlet, a carrier liquid outlet, a product outlet, a purifying section, and a heater. The inlet directs a slurry into the purifying section. The slurry comprises particles of a solid and a carrier liquid. The purifying section preferentially drives the particles of the solid towards a heating zone of the purifying section versus the carrier liquid. This displaces a first portion of the carrier liquid away from the heating zone of the purifying section. The heater heats the slurry. The carrier liquid outlet drives a majority of the carrier liquid out of the vessel. The product outlet is adjacent to the heating zone of the purifying section.
