Title: Flow regulating device for arterial catheter  systems
Inventor: YOUNG JAMES E
IPC: F16K51/00
Filed: 1980-06-06
Granted: 1982-10-26
Abstract: FLOW REGULATING DEVICE FOR ARTERIAL CATHETER SYSTEMS      ABSTRACT OF THE DISCLOSURE       A flow regulating device provides continuous, regu-lated flow of a medical fluid, as well as intermittent, manually controlled larger flows of fluid to a catheter system.  Such apparatus includes a control member having an inlet means adapted to be connected by tubing to a source of medical fluid and an outlet means adapted to be connected by tubing to a catheter.  A flexible conduit defines at least a portion of a first passage between the inlet means and outlet means of the control member.  A cylindrical, hollow extension extends from the outlet means coaxially within and to about the midsection of the flexible conduit.  Positioned in the flexible conduit is valve means adapted to open when the conduit is squeezed, thereby pro-viding the larger, intermittent, manually controlled flow of fluid to the catheter system, and to automatically close when the conduit is released.  A second passage in the control member connects the inlet and outlet means, and in combina-tion with flow restriction means therein, provides the continuous, regulated flow of fluid to the catheter system.

Abstract: ABSTRACT OF THE DISCLOSURE          A switch assembly having an actuator rod for manually actuating the switch, a deactuator rod for manually deactuating the switch and an electromagnet for electrically deactuating the switch.        A spring biasing armature is pivotally mounted on a U-frame for movement within the switch housing.  A pawl projects from the armature for engagement with a latching shoulder on the actuator rod.  When the actuator rod is depressed to an actuated position which closes the switch contacts, the armature pivots to a position in which the pawl latchingly engages the latching shoulder on the rod and retains the rod in the actuated position.        The actuator rod is released from its actuated position by movement of the pawl out of latching engagement with the latching shoulder.  Release is accomplished manually by depressing the deactuator rod which is mounted in aligment with the free end of the armature.          Depression of the rod pivots the free end of the armature such that the pawl pivots out of latching engagement with the latching shoulder of the actuator rod.  Release is ac-complished electrically by energizing the electromagnet.          The magnetic field attracts the free end of the armature, thereby pivoting the armature such that the pawl pivots out of engagement with the latching shoulder of actuating rod.

Abstract: INDUCTIVELY HEATED TOOLING AND METHOD FOR WORKING PLASTIC MEMBERS   Abstract Of The Present Invention A plastic heating tool unit is provided for cutting, sealing and like working of a relatively thin or film-like plastic element.  The tool unit may function to sever a plastic element from a web and create firm thermal attachment thereof to another member.  The tool unit includes an appropriately shaped annular or circular tool element formed of appropriate material which is responsive to an inductive field for self-generation of heat within the material.  An annular radio frequency induction coil unit is coupled to the tool element.  A heat transfer member is secured to the tool element and to a forced cooled heat sink which cools the transfer member and thereby the tool element.  The transfer member creates a selected retarded cooling rate of the tool element to provide an improved interaction of the tool member and the plastic element and for more effective heating and cooling thereof.  The tool element is forced into operative engagement with the plastic element and by appropriate shaping of the tool element may force a plastic web toward a support and thermally sever the aligned annular portion from the web.  The tool unit may be constructed to stretch a film-like plastic web, a foamed plastic web or the like during the thermal cutting thereof, and heat seal the severed plastic element to another member.  The tool unit may also seal a preformed cover element to a container assembly in an automated assembly line apparatus having a separate sealing station with a fixed induction coil and a pressure clamp unit moving with the container assembly.

Abstract: BYTE DATA ACTIVITY COMPRESSION                       Abstract In a TDMA satellite communications system, the data ports at two different earth stations have their data rates synchronized.  The origination port stores the last eight-bit byte of data in each 480-bit packet which is transmitted via the satellite.  The last byte is compared with each of the 60 bytes of data in the next channel's worth of information received from the ter-restrial source.  If all of the bytes of data in the new channel's worth of information are identical to the last byte of data transmitted from the originating port, no information is transmitted for this data port in the next TDMA frame.  The synchronized data port at the receiving earth station expects a channel's Worth of data to be received during the next TDMA frame.  The last byte of received data for the recipient data port in the last frame is stored.  If no data is received by the recipient data port in the present frame, the data port will infer that the next 60 bytes of data in the channel which would have been received in the present frame are each replications of the stored last byte of data.  The receiving port then replicates the last byte of data 60 times and delivers it to the recipient terrestrial receiver connected to the data port.  The transmitting data port will continue to not transmit succeeding channel's worth of data for every new channel whose bytes are the replication of the last byte stored from the last frame.  The recipient data port at the destination earth station will continue to infer that the succeeding channels which are not received from the originating station are in fact replications of the last byte stored from the last received channel, for every TDMA frame which does not contain a transmission from the originating data port.  Thus, without the necessity for transmitting control information such as a VAC mask to affirmatively signal the destination data port that byte replication is to be carried out, the destination station will continue to replicate succeeding channels of information for an arbitrary number of TDMA frames.
