    摘要： The present invention provides an assembly for displaying a sign, including a sign frame and one or more lights disposed on the frame, with each light including one or more electrical conductors for conducting electric current thereto from an electric power source. The display assembly includes an electrical conductor associated with the frame and connectable to the electric power source, a light socket interconnectable with the frame and having a socket opening for receiving the light inserted therein, a connector interconnectable with the light socket and having at least one electrical conductor disposed for electrical contact with the electrical conductor on the light when the light is inserted into the light socket and the light socket is interconnected with the conductor. The electrical conductor on the connector is interconnectable in electrical contact with the electrical conductor on the frame in order to establish electrical communication between the light and the electric power source. Preferably, the assembly also includes electric or electronic controls for causing continuous, blinking, sequential, or other illumination patterns for multiple lights positioned about the frame of the display assembly.

    摘要： Polybenzyls of high molecular weight and high crystallinity are obtained by polymerizing aralkyl halides in the presence of a catalyst comprising a complex of a Friedel-Crafts catalyst with a complexing agent which can be a nitroarene or a nitroalkane. The complex catalyst allows the polymerization to be run at higher temperatures and with higher rates. Yields are obtained up to 100%.

    摘要： A method and apparatus are disclosed for the mechanical sorting of mammalian spermatozoa by sex-type, into a fraction enriched in X-chromosome-bearing spermatozoa, and a fraction enriched in Y-chromosome-bearing spermatozoa. Because of their different DNA content, Y-chromosome spermatozoa are slightly smaller than X-chromosome spermatozoa. A column is packed with two sizes of beads. The size of the smaller beads is chosen such that, on average, Y-chromosome spermatozoa will readily fit into the interstices between the smaller beads, while X-chromosome spermatozoa, on average, will not readily fit into those interstices. The size of the larger beads is chosen such that the smaller beads will not readily fit into the interstices between the larger beads. A liquid sample containing the sperm is run through a column so that the liquid first encounters the larger beads, and then encounters the smaller beads. The beads act as a sieve, creating a fraction in the larger beads enriched in X-chromosome spermatozoa, and a fraction in the smaller beads enriched in Y-chromosome spermatozoa.

    摘要： Crystalline co-polybenzyls are prepared by the polymerization of 2,5-dimethylbenzyl chloride with a benzyl halide of the same series. The polymers have utility in general thermoplastic applications such as, for example, the manufacture of conduits, hoses and pipes, as coatings for wire and cables, the manufacture of seals, molds and mechanical goods, tanks and pipelinings, and in other articles of manufacture.
