Last week a company called Parabond Corp. of America, in Cambridge, Mass., disclosed its novel solution, which has been adopted by Connecticut, Rhode Island, Massachusetts. Parabond is a rubber latex compound poured into the expansion joints, where it jells. To prevent the usual separation from the concrete, it has a strong adhesive mixture. To prevent bulging, it is thickly interlarded with puffed wheat. The porous globules of puffed wheat constitute bubbles in the mixture, permitting the latex to give without forming a ridge across the highway...
...company. Alert, ambitious, quick-thinking, he was soon moved up to the position of works manager and finally, in 1928, became president. Quiet, conservative Mr. Tew kept on living in comparative modesty at nearby Hudson where, always investigating new ways to make rubber, he used to putter with latex on the kitchen stove...
...years chemists tried to make synthetic rubber by picking latex apart, deciding what it was composed of, reassembling the elements. It might have been better to look for a compound which would serve the purpose of rubber rather than duplicate its composition. The synthetic rubber which grew out of the Nieuwland researches is 40% chlorine, not an ingredient of natural rubber at all. At a chemistry symposium in Rochester, during the winter of 1925, Father Nieuwland read a paper on the formation of divinyl acetylene from acetylene and cuprous ammonium chloride. Du Font's Dr. Elmer K. Bolton...
Laytex is made from latex (rubber tree milk) from which proteins, sugars and water solubles are removed. Lengths of wire to be insulated are fed vertically through tanks containing the processed milk. At each immersion a film of milk adheres to the wire and dries, any excess falling back into the tank. Thus, by repeated dippings, the insulation is built around the conductor, the wire is accurately centred, and the wall thickness of the insulation is uniform...
Lastex and the two-way stretch are not the same thing though they were launched simultaneously. The two-way stretch is purely a matter of weaving elastic threads up & down and across the corset so that the garment "gives" with every movement of the body. Lastex, made of latex, the pure essence of rubber and tougher than its compounds, was more practical than the old rubber because it did not lose its elasticity despite long wear and frequent laundering. Thus the two-way stretch allowed corseted women to move about with freedom; the Lastex, carefully moulding the figure, kept...
