A barbed wire installation apparatus for easily installing barbed wire includes a hitch bracket to selectively engage a hitch receiver of a vehicle. A horizontal cross member is coupled to the hitch bracket. A plurality of cradle arms is coupled to the cross member. A pair of spindles is coupled to the plurality of cradle arms to secure a roll of barbed wire. A pair of upright members is coupled to the cross member. A winch is coupled to the hitch bracket and has a cable in operational communication with a topmost pulley of a plurality of pulleys coupled to the pair of upright members. A control box is coupled to the pair of upright members. A wire gripper is coupled to the winch. The wire gripper is in operational communication with a distal end of the cable to secure the barbed wire.

A media tray may include a lift plate to lift a number of sheets of media, a spool, and a first plurality of cables and a second plurality of cables each mechanically coupling the lift plate to the spool wherein the first and second plurality of cables cause the sheets of media to interface with a media pick-up roller at a horizontally divergent angle relative to a pick-up roller.

It is an object of the present invention to provide method for receiving sheets for a sheet supplying apparatus. The method includes converting an up and down motion of a tray to a rotational motion of a rotary member by a movement conversion mechanism, converting the rotational motion of the rotary member around a rotational axis to a linear motion of a cylindrical member parallel to the rotational axis by the rotary member and a cam and slider mechanism, and elastically pressing an end portion of the cylindrical member of the cam and slider mechanism in the rotational axis direction to lift the tray by a compression spring.

The present disclosure relates to methods and apparatus for launch and recovery of a remote inspection device within a liquid storage tank. In one embodiment, the tank is accessed by opening an entrance hatch and then injecting a vapor suppression foam across a surface of a stored liquid mass to form a foam layer. A launching system having a remote inspection device is attached to the entrance hatch to define a launch and recovery space sealed from an external environment and isolated from the stored liquid mass in the tank via a valve and the foam layer. The launch and recovery space is purged of hazardous vapors by injection of an inert gas prior to launch and recovery of the remote inspection device. Prior to removal of the launching system, the surface of the stored liquid mass is re-coated with vapor suppression foam.

An accumulation device is provided with a loading unit, a tensioning unit, an accumulation unit, and unloading unit and a controller. The tensioning unit comprises multiple fixed rollers capable of rolling, and movable rollers capable of rolling and arranged so as to be capable of moving with respect to the fixed rollers. Substrates are conveyed so as to move back and forth alternately between the fixed rollers and the movable rollers in a wrapped state, and a prescribed tensile force is applied to the substrates by a force acting on the moveable rollers in the direction away from the fixed rollers. The controller performs control so as to maintain the positions of the movable rollers in the tensioning unit constant.

A sheet stacking apparatus includes a tray capable of stacking plural sheets, and four wires with one end of each of them being connected to a corresponding one of portions at four corners of the tray. On the downstream side of the tray concerning a sheet feeding direction, the other end of each of two wires is connected via pulleys provided above the tray. A winding unit in the apparatus vertically moves the tray hung by the four wires by winding up or rolling down the two wires. On a side opposite to the side of the tray where the connecting portion to which one end of each of the two wires connected to the winding unit is connected, the other end of each of the remaining two wires are connected via pulleys provided above and below the tray, respectively.

A sheet supporting apparatus includes a sheet supporting portion, a regulation member, a flag portion, a detection portion, and a holding portion con. At the holding position, the holding portion supports the flag portion at the upper position in a case where the sheet supporting portion is positioned at the first position, and, at the allowing position, the holding portion allows movement of the flag portion to the lower position in a case where the sheet supporting portion is positioned at the second position. A lower end of the flag portion is positioned above the regulation surface in a case where the flag portion is positioned at the upper position, and is positioned below the regulation surface in a case where the flag portion is positioned at the lower position.
