Abstract: A gate hinge is provided which enables a gate to be maintained upright and level in a first closed position and to clear obstacles or follow the contour of the ground when swung into a second position. The gate hinge hereof can be used in combination with a support post, a gate and a conventional hinge. The gate hinge includes a hinge pin preferably mounted on a threaded rod and a bearing attached to a second rod. One of the rods is attached to the support post, the other rod is attached by mounting brackets to the gate. The pivot axis of the hinge is offset relative to the pivot axis of the other hinge, so that during swinging of the gate, its angle of inclination relative to the support post changes.

Abstract: A cubicle forming partition system has a construction which permits the use of wall panels made entirely from a cost effective volume of solid surface plastic sheets. The wall panels are rigidly secured in spaced relation from a room floor by mounts which positively engage forward and rear edge portions of the wall panels without penetrating or interrupting either of the opposed, continuous wall forming surfaces of the wall panels. Steel reinforcements in a composite pilaster and metallic hardware for mounting wall and door panels are concealed from exposure to airborne moisture and contaminants for enhancing durability of the partition system when used in moisture rich environments.

Abstract: A refrigerator includes a housing and a door hinged to the housing. The hinge carries a door opening/closing apparatus in the form of a follower slide member carried by the door and arranged to slide upwardly along a camming slide member during opening of the door, and to slide downwardly along the camming slide member during closing of the door to assist in such closing. The follower slide member is able to rotate slightly before making contact with the camming slide member upon initial opening movement of the door so that the opening/closing apparatus does not increase the force needed to initially open the door.

Abstract: An EMI/RFI shielded door assembly for use in controlling the movement of EMI/RFI in a shielded room or enclosure. The assembly has an electrically conductive frame defining a generally rectangular opening. A conductive door stop is formed on the inner surfaces of the top and side members of the frame to form a pocket into which a shielded door may be held when in its closed position. The threshold of the frame is preferably flat. A series of cam or drop hinges are used to mount the door to the frame. The hinges cause the door to be raised or lowered to or from the threshold as it is rotated on the hinges from a closed to an open position and vice versa. A low closure force gasket, e.g. less than 5 pounds per linear inch preferably formed of a conductive elastomer, is used to fill any gap that may exist between the door and the frame.

Abstract: A gate hinge embodies an upstanding casing closed at its lower end and attached to a supporting post. A pintle is fixedly mounted within the casing and concentric therewith. Lower, upper and intermediate sleeves surround the pintle within the casing with the lower sleeve fixedly mounted at the lower end of the casing. The upper and intermediate sleeves are rotatable about the pintle with the upper sleeve being attachable to a gate. The sleeves are mounted in spaced relation to the outer surface of the pintle and the inner surface of the casing to define an annular lubricant receiving reservoir between the pintle and the inner surfaces of the sleeves and an annular lubricant receiving reservoir between the outer surfaces of the sleeves and the inner surface of the casing. Coacting cam surfaces on the sleeves urge the gate toward closed position upon rotation of the upper and intermediate sleeves.
