Abstract: CONTROL SYSTEM FOR FLUID FLOW APPARATUS     Inventors:  Arnold C. Bilstad Richard I. Brown ABSTRACT OF THE DISCLOSURE         A flow control system, for example for blood plasma or other medical fluids, comprises a plurality of flexible, collapsible flow conduits for the selective and aseptic trans-fer of fluids between various locations through said conduits. Switching means are provided for selectively collapsing a plurality of separate sections of the conduit to block fluid flow therethrough, to selectively define specific and variable fluid flow paths in the flow conduit.  In accordance with this invention, the switching means defines a cam plate, which in turn defines a generally flat face positioned adjacent portions of the flow conduit.  Pivot means are provided causing the cam plate to be rotatable about an axis normal to the flat face.  Also, a cam connecting system is disclosed, to adapt it to pass through an openable door.

Abstract: ABSTRACT OF THE DISCLOSURE        Viable mammalian cells are encapsulated in a polymeric membrane to form microencapsulated beads ready for introduction into a host body.  The polymeric membrane allows passage therethrough of cell substrates and secretions, but prevents passage of larger molecules such as proteinaceous antibodies.          In this way viable cells secreting essential products such as pancreatic islet cells secreting insulin can be transplanted into a host, and be protected against the immune reactions of the antibodies of the host which would otherwise reject the foreign cells.  The cells are encapsulated from suspension in a non-solvent such as PPG, by addition thereto of a solution of a polymer (e.g. an acrylic/methacrylic acid esters copolymer) in dimethylsulfoxide.  The polymer precipitates onto the cells to encapsulate them, and the supernatants are removed.

Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus for monitoring and controlling the operation of a program-controlled computer.  The program causes the computer to produce a signature waveform characteristic of proper computer operation at a dedicated output. The presence or absence of this waveform indicates whether or not the computer is operating properly.  The apparatus monitors this output and the power supply conditions applied to the computer.  Whenever the power supply is operating outside of certain limits the apparatus produces a reset signal to the computer and a disable signal to any equipment which is being operated under control of the computer.  If a malfunction occurs in the computer operation, the apparatus produces the disable signal and a reset pulse.  If the malfunction is cleared during reset, the computer returns to normal operation upon termination of the reset pulse.  If the malfunction is not cleared and the normal operation is not resumed upon termination of the reset pulse, the disable signal continues and no further reset pulses are initiated.

Abstract: FIBER OPTIC ROTATION SENSOR          Abstract A fiber optic rotation sensor, employing the Sagnac effect, comprises all fiber optic components, positioned along a continuous, uninterrupted strand of fiber optic material.   The  rotation  sensor  includes  a  detection system utilizing a modulator for phase modulating light waves which counterpropagate through a loop formed in the fiber optic strand.  The modulator is operated at a specific frequency to eliminate amplitude modulation in the detected optical output signal.  The rotation sensor is mounted in a u- metal housing to shield it from the effects  of  ambient  magnetic  fields.   An  isolator  is utilized  to  prevent  the  optical  output  signal  from returning  to  the  laser  source.   This  advantageously reduces power losses in the system by eliminating the need for a coupler to couple the output signal to a detector.

Abstract: CELL-SEEDING PROCEDURES INVOLVING FIBROUS LATTICES                    ABSTRACT       This invention relates to the introduction of viable cells into a fibrous lattice by surgical, force-utilizing, or other manipulative techniques, all of which are referred to herein as "seeding."  One embodiment comprises an autografting technique which involves intact tissue.  Other embodiments which involve the distribution of an aqueous suspension of cells comprise centrifugal, spraying, pipetting and syringe emplacement. Each cell that survives the seeding process may reproduce into a colony of cells which grow until they reach confluence, thereby creating a uniform layer or volume of tissue.  By proper placement of cells capable of generating such colonies, the period of recovery of a wound may be drastically reduced.  In addition, research by the Applicants indicates that tissue that is regenerated using the methods of this invention to seed a lattice comprising collagen and glycosamino-glycan tends to be smoother, more uniform, less fibrotic, less scarred and more flexible than tissue that is re-generated by wound contraction or conventional auto-grafting.

Abstract: Abstract of the Disclosure A turret-type winder particularly adapted for winding of impervious sheet-type web materials, such as plastics, provides self-contained and pivotally mounted pressure rolls which contact the cores and the winding roll throughout the entire winding process and throughout the indexing of the arms from a core loading station to a roll unloading station while maintaining the relative geometry of contact such that the web contacts the pressure roll at or before contacting the winding roll for effectively excluding the entrapment of air between the winding layers.        A method of winding from a roll changer or other apparatus for providing a web of material includes the movement of the spindle end of the arms of a turret-type changer through the path of web leading to a winding roll to the back or remote side of the web so that the web lead is brought between the spindle arms and between the empty spindle and the winding roll.  Thereafter, web transfer to a new core is accomplished by placing the web onto the core at a side of the core adjacent the axis of the turret, thereby providing movement of a self-contained pressure roll into coacting engagement with the core and the building or winding roll throughout the entire winding process at a region on the periphery of the core and the roll substantially at the web lead-in point and substantially at the nip for effectively excluding air throughout the entire winding process.
