    Abstract: A pneumatically controlled liquid transfer system for delivering a liquid from a source to a delivery location, said liquid source being provided with a pneumatic cylinder for driving the liquid from said source, a pneumatically operated pinch valve of the make-before-break type and flexible conduit paths leading through the valve to the delivery location. The make-before-break pinch valve comprises a valve shell having two pistons movable laterally therein. The shell has a window. One piston has a yoke, each arm thereof having a passageway, one aligned with the other. A stop extends between the arms of the yoke. One of the flexible conduits is arranged through the window between the first piston and the yoke and the other flexible conduit is arranged also through the window but within the aligned passageways and between the piston and post. The second piston is spring biased to bear against the second conduit to place same in a normally closed condition. The first conduit is normally open. The first piston is acted upon by an external force such as air pressure to move same to a first condition wherein the piston pinches the first flexible conduit against the yoke, closing said conduit without overcoming the bias of the second piston to open the second conduit. Continued force exercised upon said first piston causes the same to move laterally within the housing to a second condition overcoming the spring bias of the second piston, to open the second conduit while the first conduit is retained in closed position. The second piston by virtue of its spring bias, will force the yoke back into its first position once the pressure on the first piston is relaxed. A manual override is provided operative upon the second piston to lock the same in open condition so that both conduits are open. This last mentioned position is utilized during down time of the apparatus concerned.

    Abstract: The system includes first and second hoppers or magazines located adjacent respective ends of a conveyor. The first magazine includes a three-sided enclosure with a vertically movable magnetic plate situated therein for holding thereagainst elongate objects having magnetizable material therein. A plurality of pawls which are deflectable inwardly of the plate are situated adjacent the movable plate. They are deflected inwardly when the plate is moved downwardly and engage and hold objects in a lowered postion when the plate moves upwardly, the plate slidingly engaging the objects during the upward movement. The lowermost position to which an object is moved is adjacent the conveyor which engages the object and moves it laterally from the first magazine. The second magazine includes a stationary magnetic plate for holding a plurality of the elongate objects thereagainst. A vertically reciprocal pushing mechanism is located beneath the plate and is operable to sequentially push objects from the conveyor onto the plate. The pushing mechanism includes an air cylinder, two rods connected to the piston rod of the cylinder and an elongate head which is movable transversely of the long axis thereof and which is detachably connected to the rods.

    Abstract: The manometer system includes a glass tubing having a U-shaped segment therein forming a manometer. One end of the tubing is connected to a vacuum line or a pressure line and the other end of the tubing is vented to atmosphere. The manometer is partially filled with mercury. The first leg of the manometer is in communication with the first end of the tubing and the second leg is in communication with the second end of the tubing with the bight portion therebetween. The second leg has an enlarged diameter portion therein intermediate the bight portion and the upper end of the second leg. The portion of tubing immediately above the enlarged diameter portion is filled with a lightweight fluid and includes a pressure indicating section. The mercury meniscus in the second leg is situated within the enlarged diameter portion so that when there is movement of the mercury meniscus in the enlarged diameter portion, there will be a much larger movement of the lightweight fluid meniscus in the pressure indicating section. A choke is connected to the second end of the tubing to dampen movement of the lightweight fluid meniscus in the pressure indicating section and to inhibit if not prevent rapid escape of mercury should a sudden increase in pressure be applied to the first end of the tubing.

    Abstract: Method for the study of the sedimentation characteristics of whole blood comprising the steps of cyclically applying greater than gravity force laterally to a thin, substantially vertically oriented column of whole blood, and rotating the column about 180 degrees about its own axis between each cycle. The sample columns are placed in tubes arranged with their long axes oriented substantially parallel to the axis of rotation of a centrifuge and the tubes are rotated about their own long axes between each cycle and only when at or substantially at rest. A preferred test operation using four cycles of 45 second duration is described with the rotation of the columns being effected by reversal of the direction of rotation of the centrifuge head at the end of each cycle. Other cycle durations are described for providing results correlatable with standarized sedimentation test procedures.

    Abstract: Apparatus which receives a train of electrical pulses from a particle analyzing device such as one which is operated in accordance with the Coulter principle, derives statistical indices from such train of pulses, stores the same in suitable storage means, receives a second train of pulses and derives the same indices from the second train of pulses, and compares the two indices. A readout device provides the comparison information. In this manner indices from one particulate system, such as for example a known sample, may be obtained and thereafter the same indices from an unknown sample may be obtained and compared with the indices from the known sample for study and analysis of the unknown particulate system.
