Abstract: Storage stable aqueous dispersions of a heat-reactive hydrophilic phenolic resin (e.g., phenol/formaldehyde) are disclosed. The dispersions comprise a base resin that is the reaction product of an aromatic alcohol and an aldehyde, and an etherified resin component selected from the group consisting of an etherified phenol/aldehyde resin, an etherified cresol/aldehyde resin, and mixtures thereof. The dispersions further comprise a protective colloid (e.g., polyvinyl alcohol). The addition of the etherified resin component in an amount of at least about 20% by weight of the base resin provides storage stability, but does not adversely affect the desirable physical and chemical characteristics (e.g., chemical resistance) of end products made from such dispersions. Moreover, the dispersions of the present invention can avoid the use of etherified resin components derived from bisphenol-A and/or xylenols, which present heath concerns in food coating applications.

Abstract: The present invention is directed to the formation of phenol alkylation polymers which release negligible phenol and formaldehyde emissions. The phenol aralkylation polymers of the present invention are derived from a phenolic monomer, at least one styrene derivative and an aryl diolefin. In addition to the phenolic monomer, styrene derivative and aryl diolefin, other reactants may be introduced to produce a product with particular properties.

Abstract: The present invention is directed to the formation of phenol alkylation polymers which release negligible phenol and formaldehyde emissions. The phenol aralkylation polymers of the present invention are derived from a phenolic monomer having at least three free reactive aromatic ring positions, at least one styrene derivative and an aryl diolefin. In addition to the phenolic monomer, styrene derivative and aryl diolefin, other reactants may be introduced to produce a product with particular properties.

Abstract: A collector feeder has a mechanism for receiving a plurality of ducts into the collector feeder, a mechanism for directing the conduits toward one another to couple adjacent conduits with each other, and an exit enables the plurality of ducts to exit the collector feeder as an assembled multi-cell single conduit unit.

Abstract: The cable puller employs a conically tapered capstan and self-contained motor both carried on a readily collapsible and portable frame. The puller is adapted for placing inside of a manhole where the capstan is aligned with the duct through which the cable is to be pulled. Several such cable pullers may be operated in concert to pull a theoretically endless fiber optic cable at a controlled speed and without exceeding the tensile strength of the cable. Tension on the cable effects the frictional gripping force between the capstan and the cable looped there around and this gripping force controls the extent to which the cable is permitted to climb up and slip down the conical incline of the capstan to a point where equilibrium is reached. A radio-controlled sensor is provided at each pulling station to signal cable stoppage faults and to respond to faults signaled by other pulling stations by shut down of all stations until the fault is corrected.
