Abstract: This lightweight explosion-mitigating assembly includes at least a containment structure and a door. The containment structure and door each include at least one set of engagement flanges. The flanges are movable between an interlocking arrangement and a non-interlocking arrangement. In the non-interlocking arrangement, the flanges are sufficiently relatively operatively free from each other to permit movement of the door relative to the containment structure between open and closed positions. On the other hand, in the interlocking arrangement, the door is in the closed position and the flanges are both mutually engageable and slidable relative to each other into mutual engagement and out of mutual engagement.

Abstract: A process for the separation of propylene from an input stream of C3 hydrocarbons containing propylene and methyl acetylene and/or propadiene and, optionally, C4 and/or higher hydrocarbons is described. The process includes subjecting the input stream to fractional distillation to separate propylene as an overhead stream leaving a bottoms stream containing the methyl acetylene and/or propadiene and the C4 and/or higher hydrocarbons, when present. A propane-containing stream is added to said input stream whereby propane is separated as part of the bottoms stream. The propylene content of the bottoms streams is maintained at less than 10% weight. The amount of propane added to the input stream is such that the weight of propane, propylene, and C4 and/or higher hydrocarbons, when present, in the bottoms stream is greater that the total weight of methyl acetylene and propadiene in the bottoms stream.

Abstract: An improved optical glass fiber ribbon unit, having the capability of providing mid-span access to individual color-coated optical glass fibers contained therein, by application of finger pressure from a human hand, is provided. The ribbon unit is made of a plurality of coated optical glass fibers each further coated with a cured color-composition, and a matrix material which binds the plurality of color-coated optical glass fibers together. A bonding force between the cured color-composition and the coated optical glass fibers is greater than a bonding force between the cured color-composition and the matrix material. The matrix material has been selected or formulated to provide a modulus and Tg sufficiently high such that when opposing pressure is applied to the ribbon unit using the fingers of a human hand, the matrix material buckles and separates from the color-coated optical glass fibers instead of compressing and absorbing the opposing pressure.
