Abstract: A storage rack with a front beam having a readily accessible wire track formed therein is disclosed. The storage rack comprises front and rear beams which are inverted generally V-shaped channels which roll on to side beams to form the shelf. The front and rear beams are secured into the side beams by interlocking projections and notches. The front and rear beams can span one or more bays of storage racks and a use simplified design to facilitate assembly. The front beam has an external lip which terminates in an upturned wall. The beam is continuous across one or more bays or racks and provides an accessible track for wire or cable to traverse a part of, or the entire length of the storage rack. The front beam further includes a lock-in angle plate mounted to the top thereof. A wire or cable traversing the beam can connect electronic panels which slide or snap into the front of the beam between the upturned wall and the angle plate.

Abstract: A storage rack with novel front and rear beams is disclosed. The beams are inverted generally V-shaped channels which roll on to side beams to form the shelf. The front and rear beams are secured into the side beams by interlocking projections and notches. The front and rear beams can span one or more bays of storage racks and a use simplified design to facilitate assembly. The front and rear beams, being continuous across one or more bays or racks, provide a track for wire or cable to traverse a part of, or the entire length of the storage rack. The wire or cable traversing the beams can connect electrical inventory control devices without the need for external cables or wire conduit.

Abstract: A froth-aid useful in frothing a carboxylated latex for use as an adhesive in the manufacture of carpets comprises in certain proportions urea, the sodium salt of condensed naphthalene sulfonic acid, a blend of about C.sub.8 to C.sub.18 fatty alcohols, ammonium or sodium lauryl sulfate and water.

Abstract: A composition is provided for use in flexible sponge rubber rug underlay of a type including about 100 parts of natural or synthetic rubber, from about 100 to about 300 parts of a reinforcing filler, and from about 50 to about 200 parts of oil. The improvement in the composition comprises from about 10 to about 40 parts of the natural or synthetic rubber being replaced by an approximately equal number of parts of a finely divided vinyl chloride polymer or copolymer. The present invention may also provide a sponge rubber of lower cost for the same apparent density.
