    摘要: Methods of fabricating multilayer circuits are presented. In accordance with the present invention, a plurality of circuit layers are stacked, one on top of the other. At least one of the circuit layers comprise a substrate composed of a polymeric material capable of undergoing bonding such as a fluoropolymeric based substrate having vias therethrough and a circuit comprised of a layer of suitable conductive material. A fusible conductive bonding material (e.g., solder) or a noble metal is applied wherever electrical connections are desired. At least one other of the circuit layers comprises a polyimide circuit (or other high temperature non-fusing polymer circuit, with or without filler or fabric reinforcement) having vias and circuits comprised of a layer of suitable conductive material with a fusible conductive bonding material (e.g., solder) or a noble metal applied wherever electrical connections are desired. Once stacked the circuits are subjected to lamination under heat and pressure to adhere each polymeric substrate to an adjacent polyimide substrate and to diffuse the noble metal or fuse the solder layers together to form an integral multilayer circuit having solid conductive interconnects.

    摘要: A document feed component is presented comprising a foamed epichlorohydrin elastomer, a curing agent, and a blowing agent. The elastomer optionally further includes activators, polymerization accelerators, and a filler material. An important feature of the present invention is that the use of a foamed epichlorohydrin elastomer in accordance with the present invention does not require the use of processing aids and migratory additives. Consequently, the document feed component of this invention has the advantage of not contaminating paper or other media with which they come into contact, even for extended periods of time, while maintaining other advantageous properties, such as a high coefficient of friction, low hardness, low compression set, and excellent resistance to ultraviolet light and ozone. The document feed component of the present invention may be shaped as a roller, wheel, belt, pad or the like.

    摘要: A door lockset, mounted on a door having an inside and outside face, has a latch bolt operated by a lever handle from the inside and by a grip handle thumb lever from the outside, the latch bolt being biased to an extended position except when retracted by operation of the handles, the inside lever handle being mounted in a parked position on a spindle connected to a lever return mechanism and having a latch operator attached thereto. An improvement in combination with the lockset, provides a mechanism for operating the latch bolt by the thumb lever without moving the inside lever from the parked position.

    摘要: An aerial enclosure for use in distributing above ground fiber optic communications signals from a signal source such as a central office to a customer site. The enclosure has first and second enclosure segments that can be separated to expose an enclosure interior where a termination panel is mounted that includes a row of terminal contact pairs to which copper cables are connected for routing conventional telecommunications signals away from the enclosure interior to a customer site. The enclosure includes a communications subsystem mounted within the enclosure having a first fiber optic portion for routing outgoing light signals to an optical network unit outside the enclosure for conversion to electrical signals. A copper portion of the communications subsystem incoming telecommunications signals back into the enclosure where they are redistributed from one or more of the plurality of terminal contact pairs by copper cables to one or more customer sites. A splice connection between a fiber optic strand from an overhead cable is spliced to the first fiber optic portion of the communications subsystem and then positioned within a splice enclosure for environmentally sealing the splice within the aerial enclosure.

    摘要: A lockset is adaptable for installation at more than one backset distance including a bolt assembly which has a latch member and a separable drawbar located within a housing assembly, a portion of which is also made up of two relatively movable portions. Operation of the lock is standard in so far as extending and retracting the bolt is concerned, while adjustment of the backset distance is accomplished by simultaneously adjusting the lengths of the bolt assembly and the housing assembly. Visual indication of backset distance is provided as is adaptability without the use of tools. Bolt throw disablement is provided when the lockset is in the transfer position for changing backset.
