Abstract: The present device is directed to a new and improved barrier gate assembly which comprises an automatic vehicle gate operating mechanism and a barrier arm assembly. The barrier arm assembly, attached to the automatic vehicle gate operating mechanism, comprises of a bracket assembly with a hinge assembly attached thereto. The hinge assembly, having a pivot axis transverse to the bracket assembly, pivotally joins the bracket assembly to a plate assembly permitting pivotal movement of the plate assembly away from the bracket assembly. The plate assembly is fixedly attached to the hinge assembly for securing and holding a barrier arm. The barrier arm longitudinally extends from the plate assembly. A magnet-type device is provided on the bracket assembly in alignment with the plate assembly to hold both the plate assembly and the barrier arm in place next to the bracket assembly while preventing pivotal movement of the hinge assembly and thereby the extended barrier arm.

Abstract: The present invention is directed to a new and improved apparatus and methods for calibrating environmental air monitor. A new calibration kit comprising a gas cylinder containing calibration gas, a preset regulator valve, a flow matching valve and tubing is disclosed which overcomes many of the prior art disadvantages. The flow matching valve compensates for deviation in calibration gas flow conditions and thus eliminating the need of a sampling bag. The flow matching valve modifies the preset regulator valve by compensating loss of pressure or flow going to the sensor in the environmental air or gas monitor. In addition when an abundance of pressure or flow is transmitted to the monitor, the flow matching valve “vents-off” the excess calibration gas. A method for calibrating a gas or air monitor is also disclosed. The method and apparatus permits a laminar flow, over a sensor located in the air monitor, of constant quantity and quality that is critically necessary for calibrating air monitors.

Abstract: A system for producing a field is disclosed. The field includes a main access well with a first branch well extending therefrom. A separator for separating oil and water is placed in the first branch well. In an alternate embodiment, the separator may be contained within the main access well. A second branch well may also extend from the main access well and may contain a disposal assembly that is operatively associated with the separator. The first and second branch wells may intersect the same reservoir or different reservoirs.

Abstract: A pressure limit valve for well tools where a valve member is moveable between a first closed portion, an open position and a second closed position. A spring for closing the valve is separated from a locking chamber which contains locking elements. The locking elements are located in a locking chamber and are held deactivated by a release sleeve which separates from the valve member in an open position. When the valve moves to the second closed position it is locked by engagement of the locking elements with a stop shoulder. In use between closely coupled inflatable packers, the valve prevents trapped pressure between the packers from affecting operation of the packer valve.

Abstract: An apparatus which provides a quick, simple visual continuity testing of fiber optic cables, patch cords, pig tails and the like; and wherein the invention comprises a light source, an adaptive interface, a power source, and a housing within said components are located; the invention provides an adaptive interface with the ability to match or connect various fiber optic connectorized endings and also bare fiber to a light source, thus permitting visual testing for the continuity and integrity of a fiber optic link.

Abstract: A rodent barrier means, made of non-conductive material, attached to an electrical cable, hawser, or the like providing for egress in a certain direction but preventing ingress from that direction. A rodent barrier means having alternative means of exit in the form of a ladder and a tapering passageway. A rodent barrier of unitary construction having a top half and a bottom half and which halves are clamped onto said electrical cable, hawser, and the like. The tapering passageway further having a safety measure in the form of a spring loaded screen door allowing for egress through said passageway but preventing ingress. The bottom half of the rodent barrier means having either weight means or otherwise being bottom heavy to thereby further provide stability in severe weather conditions.
