Abstract: A drawer system is provided having a frame, first and second drawers that are each slidable guidingly on the frame between open and closed positions, and a locking mechanism. The locking mechanism has a first blocking element mounted for movement relative to the frame between a blocking position and a neutral position and a second blocking element mounted for movement relative to the frame between a blocking position and a neutral position. A first actuating surface is provided on the first drawer, with a second actuating surface being provided on the second drawer. The first blocking element in its blocking position prevents the second blocking element from moving from its neutral position into its blocking position. The second blocking element in its blocking position prevents the first blocking element from moving from its neutral position into its blocking position.

Abstract: A fuse structure for automatically resetting fuses is in the form of a housing for enclosing a resettable fuse circuit pack. The housing comprises a plurality of identically constructed shells. A plurality of ferrule mounts is disposed on the housing, and annular indentations are disposed on the ferrule mounts. Locking surfaces are located on the shells, and ferrules are placed on the ferrule mounts. A positive stop portion is positioned on the shells, and is associated with each ferrule mount for locating the ferrules on the ferrule mounts. New fuse circuits are also provided for insertion into the fuse structure.

Abstract: A telephone protector is contained within a housing having an input connection and an output connection. The protector comprises an externally accessible fuse compartment having fuse contact pairs. A removable fuse holder capable of locating a fuse within the fuse compartment is provided. A fuse holding element is disposed on the removable fuse holder capable of holding fuses with respect to the removable fuse holder and positioning the fuse in engagement with the fuse contact pairs. Strain relief means is provided to reduce strain on the wires entering the housing.

Abstract: A fuse having a rated current for protecting electric or electronic circuitry comprises a body having a blow chamber. A fusible element is contained within the body and extends through the blow chamber. A contact is disposed on the body electrically connected to the fusible element for making an electrical connection between the fuse and the circuitry. The blow chamber is sealed around the fusible element so that thermal energy in the fusible element can increase within the blow chamber for causing the element to open when an elevated current is applied to the element. The blow chamber is sufficiently sealed around the element for retaining a pressure created therewithin by vaporization of a portion of the element; that pressure is sufficient to cause an arc produced by fusion of the element to extinguish. The body is of sufficient strength to contain the pressure within the blow chamber for allowing the fuse to fail gracefully.

Abstract: A fuse assembly has snubber/indicators which are visible through translucent lenses provided within the fuse cover, for indication and inspection of the fuse operability. The snubbers provide a shearing load upon the fuse filament so as to more positively separate the fuse segments of a ruptured filament, which snubbers may also envelop and insulate the conductor posts and separate the ruptured fuse elements so as to inhibit arcing within the "blown" fuse.

Abstract: A one-piece fastener is disclosed for loosely retaining a transversely extending branch with respect to a horizontal support wire. The fastener is molded of resilient plastic material in form of a flexible filament portion with a clip portion integrally formed at its opposite ends. Each of the clip portions have a generally tubular body with a cylindrical-shaped throughbore formed longitudinally and with an elongate slot formed lengthwise of the tubular body in direct communication with the throughbore to define a throat for receiving the support wire into the throughbore. Each end of the filament portion is connected to one of the tubular bodies at a point adjacent to its elongate slot and adjacent to one of its ends which provides an offset relationship between the flexible filament portion and the two tubular bodies.

Abstract: A plastic molded fastener is described as formed with a fastening clip and drive pin. The fastening clip has an elongate base member with an integrally formed clip member at one end and a mounting aperture adjacent the other end. The plastic drive pin extends generally perpendicular to the base member and has its pointed end held in a pre-driven position within the mounting aperture by a frangible connection. A collar is integrally formed on the base member about the mounting aperture for providing a snap fitting connection which is adapted to hold a driving tool in a stationary position. The snap fitting connection allows the drive pin to be consistently driven by the driving tool in a perpendicular path relative to the base member.
