Abstract: A subminiature fuse is disclosed comprising two terminals, a substrate, a fusible conductor, and a unitary housing. The unitary housing is sealed and provides increased mechanical strength, thus reducing the risk of a catastrophic failure of the fuse. The upper portion of the fuse terminals are shaped into finger like projections adaptable to mechanically fastening the fusible conductor and the substrate thereto thus facilitating the manufacturing process. In one embodiment the fusible conductor and adjacent portions of the terminals and substrate are coated with a ceramic coating or adhesive. The housing is sealed by ultrasonic welding or preferably in an insert molded plastic enclosure which is substantially devoid of air.

Abstract: A foam dispensing gun is provided which dispenses a urethane foam. The foam gun, in one aspect, has a dual valve member in which valve seats are moved relative to valve members to open and close flow paths through the foam gun. The valve member opens the flow paths substantially simultaneously and to substantially the same degree so that the A and B resins will be mixed in a 1:1 ratio. The gun is provided with a locking or stop mechanism to prevent accidental activation of the foam gun. In a second aspect of the invention, a disposable urethane foam gun is provided which has only one moving part and no O-rings.

Abstract: A subminiature circuit protector includes a substrate carrying a metal fuse element hermetically sealed in a glass sleeve cartridge. The fuse element may comprise a film deposited on the substrate, or, alternatively a metal strip or wire. Leads extend from opposing ends of the sleeve for connection in a circuit, and a gas is sealed in the sleeve to provide a suitable environment to improve operating lifetime and interrupting capability. A method for making a circuit protector includes placing a substrate carrying a fuse element in a glass sleeve and placing leads in contact with the fuse element. The assembly is heated in the presence of a gas below atmospheric pressure to a temperature sufficient to soften the glass. The pressure is then increased to cause the ends of the glass sleeve to form a hermetic seal about the leads.
