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: There is provided a spectral flame burner of the preatomizer type having a sample tube the outlet of which is disposed within a carrier gas conduit terminating in a nozzle. The spacing between the outlet of the sample tube and the outlet of the nozzle is adjustable during the normal operation of the analyzer system, including the burner. Improved means is provided to withdraw the outlet of the sample tube to a position in which sufficient gas pressure is developed in the sample tube to blow out any obstruction in the latter, including a lead screw mechanism operatively associated with the sample tube. The burner has an improved cap construction and a control system is provided for the burner to safely shut down the burner when a defect is detected in the burner system.

Abstract: A fluid injection device for incorporation in automated apparatus for the quantitative analysis of a substance transported in a flowing liquid stream segmented by gas bubbles or other immiscible fluid segments. The device includes a body defining an elongated fluid passageway portion. One end of the passageway portion provides an inlet for fluid or gas under pressure through a tube extending into the passageway portion from the last-mentioned end toward the other end thereof, which tube has a discharge end portion received axially within the passageway portion. An inlet for unsegmented liquid under pressure communicates with the passageway portion, upstream of the aforementioned discharge end portion of the tube, providing for axial injection of gas into the stream of liquid flowing from the liquid inlet toward the other end of the passageway portion. By varying the resistance to liquid flow in the area around the discharge end of the tube the size of the bubbles injected into the liquid stream may be changed.

Abstract: A centrifuge of the type used for a number of individual test samples in separate sample containers is dynamically balanced automatically by means of a counterbalancing mass contained in an annular chamber within the centrifuge wheel. The centrifuge wheel is mounted as an inverted pendulum about a fixed pivot and spring biased to the vertical position. The counterbalancing mass, which is at the same vertical level as the sample containers, automatically moves angularly to the counterbalancing position at speeds above the speed corresponding to the natural vibration frequency of the pendulum system.

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.

Abstract: BLOOD SAMPLES ARE SUCCESSIVELY AND CENTRIFUGALLY LOADED INTO A SAME CAPILLARY CHAMBER DEFINED IN A CONTINUOUSLY ROTATING CENTRIFUGE HEAD TO MEASURE THE RESPECTIVE PACKED CELL VOLUMES. THE CAPILLARY CHAMBER IS OPEN-ENDED AND HAS A SERPENTINE CONFIGURATION, I.E., IT REVERSES UPON ITSELF, TO TRAP AND RETAIN A FIXED VOLUME OF EACH SUCCESSIVE BLOOD SAMPLE FOR CENTRIFUGING. THE CAPILLARY CHAMBER IS PURGED OF A PACKED BLOOD SAMPLE BY THE INTRODUCTION OF A NEXT SUCCESSIVE BLOOD SAMPLE.
