    Abstract: A CONTROLLED DEFLECTION ROLL HAS A NON-ROTATIVE SHAFT AND A SUPERIMPOSED ROLL SHELL WITH RADIAL SPACE BETWEEN THE TWO. END AND AXIALLY EXTENDING SEALS ARE CONNECTED TO THE SHAFT AND BEAR AGAINST THE INSIDE OF THE ROLL SHELL TO DIVIDE THE SPACE INTO TWO COMPARTMENTS, INTO ONE OF WHICH LIQUID IS INTRODUCED UNDER PRESSURE SO THAT WHEN THE ROLL SHELL IS WORKING AGAINST A COUNTER ROLL UNDER PRESSURE, THE DEFLECTION OF THE ROLL SHELL IS CONTROLLED BY THE PRESSURE ON THE LIQUID WITH CONSEQUENT OPPOSITE BEAM DEFLECTION OF THE SHAFT. ONE OR MORE OF THESE SEALS, AND PREFERABLY ALL OF THEM, IS FORMED BY A PISTON WHICH RECIPROCATES IN A RECESS IN THE SHAFT TO AND FROM THE INSIDE OF THE ROLL, THIS PISTON HAVING AN OUTER SURFACE FACING THIS INSIDE AND IN WHICH A RECESS IS FORMED TO FORM A HYDROSTATIC BEARING PAD COOPERATING WITH THE INSIDE OF THE ROLL, THIS INSIDE FORMING WHAT IS IN EFFECT A HYDROSTATIC BEARING RUNNER. THERE IS A FLUID CONNECTION BETWEEN THIS RECESS AND THE BACK OF THE PISTON AND A SOURCE OF FLUID UNDER PRESSURE IS CONNECTED TO THE RECESS THROUGH A FLOW RESTRICTOR SO THAT THE PISTON FORMS A SEAL ACTING LIKE A HYDROSTATIC BEARING. THE SOURCE OF SEALING PRESSURE MAY BE SEPARATE FROM THAT SUPPLYING THE ROLL DEFLECTION PRESSURE, EITHER IN THE SENSE OF BEING LITERALLY A SEPARATE SOURCE OR A SOURCE WORKING THROUGH A PRESSURE CONTROLLING SYSTEM, WHEREBY THE SEALING PRESSURE MAY BE VARIED INDEPENDENTLY OF THE ROLL DEFLECTION CONTROLLING PRESSURE.

    Abstract translation: 1313927 Rollers USM CORP 2 June 1970 [3 June 1969] 26475/70标题F2U一个辊子包括一个围绕轴1旋转的卷筒壳4，留下由端部密封件6限定的环形间隔件5，并通过纵向密封件分成两个隔室 如图7所示，使得一个隔室可以通过流体压力（例如，在管线8和管线9中流动）来加压以控制壳​​体的偏转，至少一个密封件6或7包括可在腔室中滑动的活塞27 如图26所示，活塞具有加压的流体供应源，与供给到一个隔间的流体不同，该空气供给（例如经由管线23和21或32）到腔室，并且然后经由限制通道31通过 活塞到其面28面向壳体，使得活塞被推向壳体，但是防止了由流体流动从流体流动离开通道31的流体轴承接触壳体。活塞27优选地在其表面28中具有凹槽29 ，是叙述 要与轴一起弯曲。 密封件6的活塞是环形的，并且可以将它们的腔室形成在固定到轴上的环13中。 来自密封件的流体渗出可能被排出，例如 轴可以通过在辊壳4中的自对准轴承10和机架3安装，并且可以防止通过端盖3a在框架中旋转。

    Abstract: Method and apparatus for controlling the parameters of injection molding processes in a machine having a barrel with a plasticating chamber and a screw, rotatably and slidably disposed in said chamber, hopper means adjacent one end of said chamber communicating therewith and nozzle means disposed in the other end of said chamber communicating with a mold. Control of the injection molding process is achieved through an event recognition philosophy by sensing screw position, screw injection velocity, melt temperature, comparing the values at certain instances during the work cycle with known or desired values and using these values, changes of values and differences of values to monitor and initiate changes in the process parameters.

    Abstract: THE RADIAL-ACTING PRESSURE-APPLYING MEANS REQUIRED BETWEEN THE NONROTATIVE SHAFT AND THE ROTATIVE SHELL ENCIRCLING THIS SHAFT OF A CONTROLLED DEFLECTION ROLL ASSEMBLY, IS FORMED BY ONE OR MORE PISTONS WORKING IN CYLINDERS MOUNTED BY THIS SHAFT. THE ONE OR MORE PISTONS EACH HAS A HYDROSTATIC BEARING PAD ON ITS PRESSURE-APPLYING END WHICH WORKS AGAINST THE INSIDE OF THE SHELL ROLL SO THAT THIS INSIDE PROVIDES THE RUNNER OF A HYDROSTATIC BEARING ASSEMBLY.
