An insulator bushing wildlife guard having features for easier alignment and installation of the guard on the bushing. The guard has two hinged body sections of insulating material. An outer edge of each body section is provided with a plurality of flexible fingers that allow conductors to pass through from the interior to the exterior of the enclosure when the two portions of the guard are engaged. In one embodiment, the guard is spring biased toward a closed position. A handle on the back has inner grooves to make it easier to grasp and manipulate the guard using a shotgun stick. On a lower front side of each portion of the guard, spaced-apart, curved, horizontal upper and lower flanges help align the guard with the topmost skirt of a bushing. Medial walls having a curved, sloped, concave or otherwise inwardly-directed configuration between the two flanges facilitate forcing the guard open by pushing it against the bushing. An external tab limiter, disposed above the upper flange, makes it difficult to install the guard over any part of the bushing other than the topmost skirt of the bushing. An alternative version of the guard has a releasable trigger, which is used to hold the two portions in an open position until the bushing or power line displaces the trigger and allows the biasing spring to close the two cover portions. The guard is provided with a handle for grasping by a manipulator tool. In one embodiment the handle is provided with inner grooves for grasping by a shotgun stick. In another embodiment, an adapter releasably engages the handle and provides means for attachment to a hotstick.

A non-refillable valve is provided that allows for an initial filling of a container, but prevents subsequent refilling of the container. In one embodiment, the valve includes a valve core having a retaining means for maintaining the valve core in an open or non-sealing position to allow flow through the valve and filling of the container. The valve core may then be advanced to seal the container, and subsequently selectively operated to discharge the container as desired. Further refilling of the container is prevented by the force of fluid reentering the valve which forces the valve core to its seated engagement with the valve seat.

A multi-phase separation apparatus shapes fluid flow in a flow shaping line preferably shaped to have a plurality of loops with consecutively decreasing diameters. Shaping the two-phase flow drives the heavier, denser fluids to the outside wall of the flow shaping line and allows the lighter, less dense fluids such as gas to occupy the inner wall of the flow shaping line. With the gas positioned on the inner wall, an exit port on the inner wall permits a majority, if not all, of the gas, along with a minimal amount of liquid, to be diverted to a conventional gas-liquid separator at a flow rate much lower than the total flow rate within the flow shaping line. The remaining liquid flow in the flow shaping line is subsequently introduced into an adjustable phase splitter to separate different liquid components from one another.

A centrifuge of the type having an outer bowl and an inner rotor both of which are generally cylindrical and rotate in the same direction but at slightly different rates separates slurry fed into the interior of the rotor into solids and liquid. An auger flight on the outside surface of the rotor carries the solids along the annular channel between the outside of the rotor and the inside of the bowl. The slurry is fed into a chamber at one end of the rotor and through outlet holes in the sides of the rotor into the channel. An end plate of the chamber has a forwardly projecting domed central nose which extends into the flowing slurry. Transverse guide plates of the rotor act to engage the slurry and accelerate it into rotation with the rotor before escaping through the holes. The guide plates are shaped with curved angularly projecting ribs on the downstream side in front of the hole over which the slurry flows in a smooth path before exiting the hole.

The rack posts are configured to be able to change an interval therebetween and select a first state in which the engaging hooks can be disengaged from the engaging holes and a second state in which the movement of the receiver is restricted while the engaging hooks be kept to engage in the engaging holes by changing the interval between the rack posts.

A two phase gas-liquid separation apparatus is provided that shapes the flow in a flow shaping line. Shaping the two-phase flow allows centrifugal force to send the heavier, denser liquid to the outside wall of the flow shaping line and allows the lighter, less dense vapor or gas to occupy the inner wall of the flow shaping line. With the gas positioned on the inner wall of the flow shaping line, an exit port on the inner wall will allow for the majority, if not all, of the gas, along with a low amount of liquid, to be sent to a conventional separator. A high ratio of vapor / liquid at a flow rate much lower than the total flow rate within the flow shaping line is sent to the conventional separator. This allows for efficient separation of the vapor from the liquid with the use of a smaller conventional separator.

The valve is then selectively operated in a third or open position to discharge the container as desired. Subsequent refilling of the container is prevented by the force of fluid reentering the valve which forces the valve core to its seated engagement with the valve seat.
