  • Patent number: 9339575
    Abstract: Medical devices, including medical adhesives, need to be sterile before application to a patient. A dry heat sterilization process can sterilize medical adhesives for patient application. The dry heat sterilization process can be validated for particular equipment arrangements and medical adhesives being utilized.

  • Patent number: 6774749
    Abstract: A circuit breaker for interrupting the flow of current upon the detection of excess current or temperature is provided which comprises a housing, a trip armature plate, a trip armature frame, and a bias spring. The trip armature plate has at least two pivot tabs extending laterally on opposite edges that are inserted into a pivot elongated slot, which is located at an open end of the trip armature frame, and a pivot aperture, which is located at the opposite end of the trip armature frame, respectively. A bias spring is used for securing the pivot tabs into the pivot elongated slot and the pivot aperture, and for urging the trip armature plate pivotably outwardly about the pivot tabs away from the trip armature frame. The circuit breaker also comprises a trip cross bar having at least two fingers that are used to engage optional circuit breaker accessories and that are located asymmetrically to allow the interchangeability of the accessories.

  • Patent number: 6636133
    Abstract: A circuit breaker comprises a line terminal, a middle terminal, and a load terminal, at least one of which is constructed from a positive temperature coefficient material and configured for introducing a predetermined resistance into the current path of the circuit breaker. The predetermined resistance is intended to limit current reaching a bi-metallic trip element as temperature rises so as to protect the bi-metallic trip element from excessive thermal stress, where the predetermined resistance increases with the increased temperature.

  • Patent number: 6628185
    Abstract: A circuit breaker for interrupting the flow of current upon the detection of excess current or temperature is provided that has a current conducting blade mounted on a blade cross bar, which has a blade biasing spring for urging the blade to a first pivotal position on the blade cross bar during the open, closed, and tripped operation of the breaker, and for latching the blade in a second pivotal position on the blade cross bar upon the occurrence of a blown-open action of the breaker. The spring is a torsion spring that is coiled around a spring mounting pin, having a first end leg extending outwardly and formed into a hook anchored in a hook accommodating opening, and having a second end leg extending outwardly and cantilevered in contact with a spring follower pin. The second end of this leg is bent away from the spring follower pin to reduce the spring force exerted between the blade cross bar and the blade upon the occurrence of a blow-open action of the circuit breaker.

  • Patent number: 6624373
    Abstract: A circuit breaker for interrupting the flow of current upon the detection of excess current or temperature is provided that contains an arc plate assembly which includes a pair of insulative mounting plates having mounted thereon a set of arc plates arranged in an arcuate array generally tracing the arcuate path of movement of a circuit breaker moveable contact blade. A baffle plate is mounted between the insulative mounting plates and positioned above the uppermost arc plate in the set of arc plates for blocking arc-formed debris from projection into the operating mechanism of said circuit breaker. Mounting tabs, which are extending toward the insulative mounting plates from edges of the arc plates, are being used to connect the mounting plates with the arc plates by passing the tabs through corresponding apertures located in the mounting plates. The tabs are crimped against the exterior surface of the mounting plates.

  • Publication number: 20030052762
    Abstract: A circuit breaker comprising a fixed contact; a moveable contact, which is moveable into and out of electrically conductive engagement with said fixed contact; a line terminal operatively coupling said fixed contact with a circuit to be protected by said circuit breaker; a middle terminal operatively coupling said moveable contact with said circuit to be protected, in series with said line terminal, said fixed contact and said moveable contact; and a load terminal in series with said middle terminal and operatively coupling said circuit breaker to a load, a trip mechanism responsive to at least a thermal trip element for causing the moveable contact to move out of engagement with the fixed contact in response to a given amount of thermal energy caused by current over time passing through a circuit breaker current path comprising said fixed contact, said movable contact, said line terminal, said middle terminal, said load terminal and said thermal trip element from a circuit to be protected, wherein at least o

  • Patent number: 4790579
    Abstract: A two-piece spring latch assembly operable as a closure device for a load center cabinet, wherein the latch assembly is slidably engagable with the door of a load center cabinet. The latch assembly includes a sliding latch body having a top surface with a depression for facilitating engagement of the latch body. The latch body also includes a latch member for engaging the frame of the load center cabinet. A latch spring is mounted to the latch member and defines a spring member for urging the sliding latch body into a latched position. The latch spring also defines a latch bearing surface and a strike bearing surface. These surfaces are fabricated from the same material as the spring member and resist wear through repeated cycles of engagement and disengagement with the frame of the load center cabinet.
