Abstract: Systems for shredding fibrous material are described. In some embodiments, the system includes a cart that includes a hopper that includes an auger motor for shredding fibrous material and a blower motor configured to blow the shredded fibrous material onto structures for fireproofing. The cart may include a handle, one or more wheels, and/or forklift apertures to aid in transport.

Abstract: An electrical connection with first and second electrical connectors are adapted to engage each other to form an electrical connection. An electrical wire is connected to each connector. At least one of the connectors has a contact formed of a conductive elastomeric material with conductive particles dispersed in the material, which is shaped to deform when compressed. When the first and second connector elements engage each other contact(s) formed of the elastomeric material will deform to cause electrically conductive particles in the elastomeric material to form an enhanced electrically conductive path through the elastomeric material.

Abstract: The present invention relates to a seal for an electric cable that is connected to a second cable in a confined location, in which a first and second lengths of insulated electrical cable extend into a confined location and a connector connects the first and second lengths of cable, and a method for forming such a seal. A thin layer of conductive material covers a first portion of the first length of insulated electrical cable, with a second portion of the insulated electrical cable projecting beyond the conductive material for connection to the connector and providing an exposed end of the conductive material.
