Abstract: A split hinge made of a first hinge portion having a first cover that is operatively coupled to two first leaves, and a second hinge portion having a second cover that is operatively coupled to two second leaves. The first leaves, the second leaves, the first cover, and/or the second cover may have the same or different lengths. The first leaves may have first leaf lengths that are greater than or less than the first cover, while the second leaves may have second leaf lengths that are greater than or less than the second cover. The first cover may extend over the first leaves, the second cover may extend over the second leaves, and a portion of the first cover may extend over a portion of the second leaves or a portion of the second cover may extend over a portion of the first leaves to form the split hinge.

Abstract: An enclosure installed on oil well equipment to capture escaping gas emissions and recover them using intermittent use of a vapor recovery unit which evacuates the gas that slowly accumulates in the enclosure to a custody line for commercial or treatment elsewhere.

Abstract: An armrest cover locking mechanism for an armrest having a body with a storage compartment and a cover which is pivotally mounted to the armrest body for movement between a closed position for normal use of the armrest and an open position for access to items within the storage compartment. The latching system includes a latch mounted to the forward edge of the cover and extending downwardly into the storage bin and latchably engaging a spring-loaded, push-button slide which includes a latch plate which engages the latch of the cover when in a normal position. Upon depression of a push-button actuator associated with the latch slide, the latch plate clears the cover latch allowing the cover to be opened when the armrest is in a horizontal position. The slide is slidably mounted within a housing and includes a curvilinear pendulum pivotally mounted to the slide such that when the armrest is in a horizontal position, the slide can move freely within the housing.
