Abstract: ABSTRACT OF THE DISCLOSURE            ULTRASENSITIVE APPARATUS AND METHOD FOR DETECTING CHANGE IN FLUID FLOW CONDITIONS IN A  FLOWLINE OF A PRODUCING OIL WELL, OR THE LIKE            Transient change in heat flux due to ultrasmall variation in flow conditions, say from flow-to-no flow within a flowline of a wellhead connected to an oil well penetrating an earth formation, is surprisingly useful in pinpointing the occurrence of adverse "pump pounding" during the production cycle of the well.  In one respect, the change in flux is monitored within each flowline using a heat flux transducer/ meter in series with a pump controller.  Cascading the signal output, i.e. serially combining the outputs of N thermocouples the transducer/meter, enhances sensitivity.  In a preferred case, N is about 80 but can be as high as 320, if desired.

Abstract: IMPROVED UNLOADING CONTROL SYSTEM FOR HELICAL SCREW COMPRESSOR REFRIGERATION SYSTEM               ABSTRACT OF THE DISCLOSURE A check valve within a closed loop refrigeration system isolates the evaporator from the helical screw compressor.  A normally open, solenoid operated valve is positioned within an unload line having one end coupled to a drive cylinder outboard chamber to the side of the piston opposite an inboard chamber which opens to compressor discharge pressure.  The other end of the unload line is connected to the system low pressure  side,  downstream of the check valve.  The same drive cylinder outboard chamber opens via a load line  to  the  system  high pressure  side  through  a normally closed solenoid operated valve.  Upon com-pressor shut down, the outboard chamber is vented to the system low pressure side, while the opposite side of the unloader drive cylinder piston sees the com-pressor high side,  thus driving the slide valve to full unload position and eliminating the coil spring normally needed  to  drive  the  slide valve to that position.

Abstract: ABSTRACT OF THE DISCLOSURE The method for separating whole blood into the com-ponents thereof is practiced with and within a separation chamber mounted in a centrifuge device during centrifuga-tion of the chamber, the chamber having inner (130) and outer (160) wall surfaces and first (131, 132; 181, 182 183) and second (133, 134; 185, 186) side edges. The meth-od comprises the steps of:  arranging and configuring the chamber such that it has (a) an inlet (142) on the first side (131, 132; 181, 182, 183) thereof through which whole blood is received,  (b) a first upper outlet (122) at the top of the chamber from which plasma with particles there-in is withdrawn, (c) a second lower outlet (190) at the bottom corner of the chamber on the outer wall thereof from which red blood cells are withdrawn, and (d) the in-ner wall surface (130) positioned in a plane including a tangent to a circle about the axis of rotation and the plane positioned about normal (in a vertical direction) to a radius extending from the axis of rotation of the centrifuge device.  The method and chamber direct whole blood into the chamber from the first side (131, 132; 181, 182, 183) thereof at a point between the bottom and top of the chamber.  Heavier particles such as red blood cells are directed downwardly and outwardly along the outer wall surface (160) toward the lower bottom corner (190) of the chamber.  At the same time, plasma is directed up-wardly along the inner wall surface of the chamber so that there is separation of white blood cells, particularly granulocytes, from the whole blood which are directed with the plasma, toward and out the first outlet (122) from the chamber.

A spatially moveable piston rod in the form of a universal or ball pivot-link chain is connected with the piston.  The piston rod is lengthwise guided by tensioning or tie bolts internally of the  cylinder, these tensioning bolts clamping towards one another both of the cylinder heads and piercingly extending through the cylinder.  Externally of the piston-and-cylinder unit the piston rod is guided within a guide tube which is connected with one of the cylinder heads.  This guide tube can possess a random spatial extent.   At the piston rod there is attached a coupling element with which there can be coupled the object or the like which is to be moved.  This coupling element extends through a longitudinal slot provided in the guide tube.          The spatial mobility of the piston rod enables guiding the piston rod externally of the piston-and-cylinder unit in a random direction.

Abstract: ABSTRACT OF THE DISCLOSURE                This machine has a turret which rotates about a horizontal axis on a frame that is movable into and out of a loading position adjacent a rotary extruder. The turret comprises a tubular shaft, a plurality of axially spaced, circular plates secured to the shaft coaxially thereof, and a plurality of identical, radially projecting panels that are secured in registering radial slots in the circular plates. A separate mold is mounted in the angular space between each pair of adjacent panels, and comprises a stationary section fixed to one of the circular plates for rotation therewith, and a movable section mounted for reciprocation by a collapsible linkage into and out of a closed position against the associated stationary section.          As each mold rotates past the loading station the associated linkage closes the movable mold section, a supply of molten molding material is then fed by the extruder to an axial bore in the stationary section of the mold, a hydraulically actuated ram then enters the now-loaded bore and forces the molding material into a cavity in the mold, the ram is then withdrawn, and there-after the mold sections are separated and the molding part is ejected from the turret. The size of the turret can readily be increased or decreased merely by changing the overall sizes of the panels and the associated supporting plates.
