Abstract: An insulting cover for industrial control components employs a cover support that may simply attached to existing or specially prepared structures on the control component, which supports a door that may be opened or closed for access to the control component. A variety of different covers may be simply generated using CAD templates executed to cut sheets of plastic that may be formed with relatively simple and low cost techniques.

Abstract: A V-band coupling for use on an explosion-proof enclosure. The V-band coupling includes a V-band having a toughened layer along its interior surfaces for gripping the flanges on the enclosure which the V-band engages when it is installed on the enclosure. The roughened layer results in an increased coefficient of friction between the V-band and flanges which is effective for reducing the load experienced by the trunnion joints of the coupling during explosion events thereby allowing the explosion-proof enclosure to withstand high internal pressures without system failure.

Abstract: One or more sets of auxiliary contacts are contained within a cartridge which mounts to the side of an electromagnetic contactor. The cartridge snaps into position and is firmly supported at each of its ends. A cam member slidably mounts to the cartridge and couples to the contactor actuator. It includes a sloping cam surface which engages a cam follower pivotally mounted within the cartridge and translates the sliding motion of the contactor actuator into a pivotal motion which operates the auxiliary contacts.
