Title: Method of apparatus for expanding and sealing a sleeve into a surrounding tube
Inventor: RABE GEORGE B
IPC: B21D39/04
Filed: 1988-07-20
Granted: 1994-01-18
Abstract: METHOD OF APPARATUS FOR EXPANDING AND SEALING A SLEEVE INTO A SURROUNDING TUBE          ABSTRACT OF DISCLOSURE          A  method  and  apparatus  for  locating  a  sleeve within a surrounding  tube  and  pressure-tightly  sealing the sleeve within  the  tube  to repair leaks in the tube.  The sealing method  utilizes  dual  elongated  pressurizable tools.  The first    tool   device   includes   a   housing   having   a reduced-diameter  forward  extension  portion  attached to a front  cylinder,  and  containing  a rear piston.  The front cylinder,  is  attached to a collet having multiple radially expandable fingers and contains a front piston attached to a tapered mandrel which is axially movable within the fingers, and  has  a  forward  tapered  nose  portion  to  facilitate inserting the tool into a tube.  The rear piston is attached to  the  front  piston by an elongated rod.  By pressurizing the  tool  front  piston  by  a hydraulic fluid pressurizing unit,  the  mandrel  is  forced  forward  through the collet fingers to expand the fingers against the sleeve and thereby expand  the  sleeve  tightly  into the tube to form the seal joint.   After  withdrawing the tool from the tube, the tool rear  piston  is  similarly pressurized to retract the front piston   and   attached  mandrel  back  through  the  collet expandable  fingers  to  reset the tool prior to its further use.   The  second  tool  includes  a  housing containing an axially  movable  piston  and  a  forward reduced  diameter portion  and  having  an elastic expander unit for inserting into  the sleeve and tube in a tubesheet.  The expander unit consists  of  at  least  two  elastic  rings  composed of an elastomer material and each having a chamfer provided at the moved rearwardly to axially compress and expand the expander rings  radially  outwardly sufficiently to expand the sleeve firmly  into  the  tube  and  provide  a pressure-tight seal therebetween.   Following  such expansion of the sleeve, the piston  is  pressurized  and  moved  forward  to release the compression on the expander unit rings, so that the tool can be  easily  withdrawn  from the expanded sleeve and tube and inserted into another sleeve and tube for repeated usage.

Title: Periodontal probe system
Inventor: GOTT F KENNETH JR
IPC: A61C19/04
Filed: 1988-08-19
Granted: 1992-03-17
Abstract: PERIODONTAL PROBE SYSTEM            ABSTRACT     A  periodontal probe system for  measurement,  storage, and display of periodontal pocket depth,  gingival level and periodontal attachment level of the teeth.  In the system, a periodontal probe instrument includes an elongate tip with a measurement   arrangement   that   simultaneously   measures periodontal pocket depth,  gingival level,   and periodontal attachment  level  at  each of a plurality  of  probe  sites around a tooth.   The measurement arrangement provides depth signals indicative of the pocket depth and attachment  level measured.  Gingival  level  is  computed as  the  arithmetic difference  between  the  attachment level  and  the  pocket depth.   A pressure sensor in the probe provides a  pressure signal  indicative of the pressure acting on the tip of  the probe.   A  signal  processing  apparatus  is  connected  to receive  the  pressure  signal and  the  depth  signals.   A periodontal  measurement is made by inserting the tip of the probe  into  a  gum  pocket  and  gradually  increasing  the pressure   on  the  probe  tip  after   insertion.    At   a predetermined   pressure   level,   the  signal   processing apparatus  samples the depth signals and converts them  into measurement  signals  corresponding  to  pocket  depth   and attachment   level.    The   signal  processor   accumulates measurement  signals  in  an  examination  file  format.   A display  apparatus  responds to converted depth  signals  by displaying  pocket depth,  gingival  level,  and  attachment level for the tooth being measured in a dental chart format. In  the  primary  embodiment,  the  measurement  arrangement [ORILPA.H17]     includes an  array of opto-electronic elements disposed  on the probe tip and an optical shield slidably disposed on the probe tip over the array of opto-electrical elements.   When the  probe tip is inserted into a gum  pocket,  the  optical shield  engages  the  crown  of  the  tooth,  serving  as  a reference point while the tip is moved into the pocket.  The ambient  lighting  of the high-intensity dental  examination lamp  illuminates  the probe  tip,  thereby  energizing  the array.   When  the predetermined pressure level is  reached, the  signals developed by the array are provided in sequence to   the  signal processor.   The signal  sequence  includes dark-light  transitions  where elements were  shielded  from illumination  by the movable optical shield and by  the  gum pocket.    Since   the  length  of  the  probe  tip  and   a reproducible  reference  point  are  known,  the  dark-light transitions are directly convertible into periodontal pocket depth and attachment level measurements.

Title: Hierarchial arbitration system
Inventor: KENT ALLAN
IPC: G06F15/17
Filed: 1988-10-14
Granted: 1993-04-27
Abstract: HIERARCHICAL ARBITRATION SYSTEM                   ABSTRACT      A hierarchical arbitration system is especially useful in a computer interconnect coupler having a set of junctors which are assigned to channel transmitters and channel receivers for the routing of messages from the channel receivers to the channel transmitters.  When a message is received by a channel receiver, the channel receiver stores the beginning portion of the message in a first-in-first-out buffer, and sends a route message request to central switch logic.  If the destination transmitter or receiver is busy, the central logic places the message request on a destination queue and returns a signal to the requesting source transmitter to turn on a flow control signal which is transmitted back to the data processing device having originated the message.  To permit incremental expansion of the coupler to accommodate an increased number of channels, additional channel interface boards may be added and a hierarchical rotating priority scheme enables the additional channels to have equal priority with the previously existing channels without requiring reprogramming.  A ring channel arbitrator is provided for selecting a particular one of the boards during each cycle when a service request is presented and each channel interface board includes a ring channel arbitrator for selecting on the board a particular one of the channels which have presented a service request.  Moreover, the processing and queueing of routing requests is made more effective by grouping the requests into different priority levels and using separate but duplicate arbitration logic to resolve simultaneous requests within the same priority group.
