Abstract: This involves an in vitro assay system to screen for mutagenic and/or carcinogenic agents based on alterations in the fidelity of DNA synthesis. In the system, chemicals will be tested for their mutagenicity or carcinogenicity by measuring increases in the number of mistakes incorporated by purified DNA polymerases using synthetic polynucleotide templates. This system offers the advantage of performing this analysis in the test tube so that all parameters in the reaction can be monitored. Agents that enhance misincorporation during DNA synthesis would be predicted to have a higher probability of being mutagens or carcinogens in the human population.

Abstract: The invention concerns heaters, particularly for sports benches and more especially for the benches on which substitute players of the team sit during games. In the preferred form, a self-contained heater such as a combustion operated construction heater with blower produces the heat behind the bench, and the heat is conducted through a conduit into the space beneath the bench, and then through a T-conduit in either direction to points from which it is distributed. The space beneath the bench confines the heat on the front, back, sides and bottom. Heat is distributed through openings in the top of the bench toward the back, and also through openings in the front of the bench, which may be at the top of the front of the bench and at the bottom of the bench. In a less preferred embodiment, heaters may be in spaces continuous with the bench.

Abstract: A dual outlet extrusion flat film die assembly for various thermo-extrudable materials includes split manifold chambers separated from each other by a rigid centerplate. Each portion of the die in the direction behind the flow materials includes a heat sink slot behind the manifold. Each manifold tapers toward its own die mouth; has separate melt inlets adapted for center, top or end feed operations; has separate pre-land and final land surfaces leading to individual outlet openings for precise control of melt flow; and has separate heat control means allowing precise temperature control for each melt as it flows throughout the die. Temperature differentials ranging from O.degree. to 200.degree.F. are obtainable between the extruded layers. A differential push-pull adjustment system for each movable lip of each outlet opening includes opposed alternatingly staggered thimble bolts to precise control of each individual layer profile.

Abstract: A multiple outlet flat film die apparatus and process which extrude separate streams of material to form any of various composites which may involve joining of similar or dissimilar materials, which includes individual manifold chambers separated from each other by heat insulating means inbetween. The heat insulating means in between such as for example heat insulating material between plates retards heat transfer between the materials. Each manifold is tapered toward its own die mouth; has separate melt inlets adapted for center, top and/or end feed operations; has separate pre-land and final land surfaces leading to individual outlet openings for precise control of melt flow; and has separate heat control means allowing precise temperature control for each melt as it flows toward the die. Temperature differentials may be extensive and may approach the difference between the original temperature of the melt delivered to each manifold. Heat differentials of 0.degree. to 200.degree.F. are an example.
