Abstract: A wall penetrator sleeve system and method for using same provides an encasement for wires and cables passing through a wall or floor. The sleeve system is particularly useful in penetrating firewalls without violating the applicable fire codes. In one embodiment of the invention, the system includes an elongated conduit having a toothed end capable of penetrating the desired surface. The system also includes appropriate securing devices for tightly retaining the conduit in place. In another embodiment, the securing devices include at least one flat washer and a sliding washer lock on each side of the wall.

Abstract: A sleeve system and method for using same provides an encasement for wires and cables passing through a wall or floor. The sleeve system is particularly useful in allowing the walls within a building to meet fire code requirements. The sleeve system can be used regardless of whether the wiring or cabling has already been installed through the wall or floor. The invention includes a pair of mating sleeve units individually inserted around the cables through the wall or floor and appropriate securing devices for tightly retaining the sleeve units in place. In one embodiment, the securing devices include at least one slotted flange and a slotted coupler on each side of the wall. The sleeve construction also allows easy installation of additional cables through the sleeve.

Abstract: The production of novel polyester resins is disclosed as is the preparation of high solids coatings and paints containing the same. The polyester resins are produced by reacting a mixture comprising:(a) A saturated fatty acid having from 8 to 18 carbon atoms in an amount between about 3 and about 8 percent;(b) A polyol in an amount between 40 and 50 percent, said polyol consisting of between about 55 and 75 percent of a triol with the remainder being a diol;(c) A polycarboxylic acid in an amount of about 45 to about 55 percent, said polycarboxylic acid consisting of between 65 and 75 percent of an aromatic polycarboxylic acid with the remainder being aliphatic acid having from 4 to 10 carbon atoms.The coatings and paints are preferably prepared by reacting the polyester resin with an aminoplast resin to cause cross-linking.
