Abstract: A wireway channel assembly is provided for assuring unimpaired access to terminals of terminal strips placed in close lateral proximity to relatively deep wireways. A channel member having a substantially "U" shaped cross section includes at least one oblique flange portion in a side thereof. A first wireway is mounted to the inside of the "U" at the base thereof,and a second wireway is mounted to the outside of the side of the channel including the flange portion. A terminal strip is mounted to the flange portion. Wires to be terminated at the terminal strip are routed through openings in the sides of the wireways to the terminals as is conventional.

Abstract: In reaction injection molding facilities of the recirculation type, a closed loop system controls the addition of a gas to a mixture of liquid and gas. The system takes a sample volume of the liquid and forces a plunger into the sample volume. The distance travelled by the plunger between two preset pressures of the sample is measured and compared to a reference distance to get a control signal that is used to operate a valve that controls gas admission to the mixture.
