  • Publication number: 20240101336
    Abstract: Systems and methods of making a glove pack and for removing gloves from the glove pack are disclosed. The glove pack includes a stack of gloves. The stack of gloves includes a first glove engaging a second glove. The first and second gloves each have an exterior gripping surface. Each exterior gripping surface of the first and second gloves engages and adheres to the exterior gripping surface of the other of the first or second glove in the stack of gloves thereby adhering the first and second gloves together in the stack of gloves such that when the first glove is removed from the stack of gloves at least a portion of the second glove moves with the first glove.

  • Patent number: 5157369
    Abstract: A thermally and manually operable circuit breaker switch has a housing and first and second conductive plates mounted in the housing. This first plate has a first contact. A cantilevered bimetallic blade is mounted on the second plate and has a free end and a second contact. This second contact is mounted on the free end opposite the first contact. The switch also has a push button with a lateral isolating tab slidably mounted together in the housing. A spring is mounted in the housing for outwardly urging the push button and causing the tab to keep apart the first and second contacts. Also, included is a push rod slidably mounted in the housing transverse to the length of the bimetallic blade and aligned with its free end. Thus, depression of the push rod flexes the blade and separates the first and second contacts to allow the tab to keep the contacts apart.
