    Abstract: NEW AND IMPROVED APPARATUS FOR ELIMINATING AND/OR DETECTING SCATTER SIGNALS FROM THE RADIATION SCATTERED BY SCATTERING PARTICLES IN THE SAMPLE FLAME OF ATOMIC FLUORESCENCE SPECTROSCOPY ANALYSIS MEANS ARE PROVIDED, AND COMPRISE MEANS TO CONVERT THE SCATTERED RADIATION TO RELATIVELY HIGH FREQUENCY SCATTER SIGNALS WHICH OCCUPY A HIGHER FRE-

    QUENCY REGION OF THE OUTPUT SIGNAL FREQUENCY SPECTRUM THAN THAT OCCUPIED BY THE ATOMIC FLUORESCENCE ANALYSIS OUTPUT SIGNAL, AND MEANS TO SEPARATE SAID SCATTER SIGNALS FROM SAID OUTPUT SIGNAL TO ELIMINATE THE FORMER FROM THE LATTER AND/ OR TO ENABLE DETECTION OF SAID SCATTER SIGNALS.

    Abstract: A dispenser including a container body having a mouth. A permanent liquid seal across the mouth has a pair of ducts approaching the bottom of the container and opening thereinto. The ducts extend upwardly through the seal, having their upper ends spaced apart. Before use, a short length of flexible tubing interconnects the upper ends of the ducts to prevent leakage and spillage. One end of the tubing may be disconnected and then connected to a suction inlet so that the connected one of the pair of ducts becomes an aspirating tube and the other provides an air inlet. Multiple container bodies may be supported together.

    Abstract: A tundish receiving a first molten metal and a closed end mold are moved apart relative to each other so that the mold forms a solidified shell of a billet, molten metal flowing through the solidified shell to the mold. During the casting, a second or altered molten metal is introduced into the tundish to flow through the elongating billet so that a continuously cast billet is produced with a core of one metal, a layer of alloyed metals, and a shell of another metal. Billets may be produced with steel cores and stainless steel shells, ''''killed'''' steel cores and ''''rimmed'''' steel shells, and other combinations. Tubing may also be formed by the continued relative separation of the tundish and the mold after the source of molten metal is exhausted.
