Inventor: BREARLEY JOHN R
IPC: H04Q1/00
Filed: 1988-06-27
Granted: 1992-11-03
Abstract: METHOD OF OPERATING A PACKET SWITCHING NETWORK            Abstract of the Disclosure A method of operating a packet switching network is disclosed in which a Systems Network Architecture (SNA) computer can control a remote terminal cluster controller and terminals coupled thereto via a switched virtual circuit connection to the terminal cluster controller.  The terminals coupled to the terminal cluster controller are able to establish switched virtual circuit connections to other compatible computers, independent of the computer by which the terminal cluster controller is controlled.  This is achieved by an access module of the network, to which the terminal cluster controller is connected, presenting different representations of the terminal configuration to the different computers.                             - i -

Title: Combined pacemaker parameter and vital sign monitor
Inventor: PLATT HARRY L
IPC: A61N1/372
Filed: 1988-06-29
Granted: 1994-01-25
Abstract: ABSTRACT A portable combined pacemaker parameter and vital sign monitor which acquires data relating to a patient's ECG wave form and pacemaker wave form by means of electrodes (20-23) and displays the derived wave forms on self contained display means (31).  The monitor also stores data derived from the wave forms for subsequent recall and analysis.  The monitor displays wave form information in such a way that the relationship in time between the ECG wave form and the pacemaker wave form is immediately clear to a user.  The monitor is particularly useful for the portable measurement of ECG and/or pacemaker wave forms and for the ongoing analysis of the condition of a working pacemaker in vivo.

Title: Bagpipes and a bag therefor
Inventor: GILBERT GARY
IPC: G10D7/06
Filed: 1988-09-28
Granted: 1991-01-22
Abstract: ABSTRACT            BAGPIPES AND A PIPE BAG THEREFOR            A pipe bag  is constructed  from  a  flexible  composite material  which  is airtight  but  readily  permits  the transmission of moisture vapour.   At least one layer of the   flexible  composite  material   is   a continuous hydrophilic layer.  When a moisture vapour concentration gradient  is  present  across  said hydrophilic layer  it transfers substantial amounts of water through the layer by absorbing water on the side of the layer at which the higher water vapour concentration exists, and desorbing water on the opposite side of the layer at which the water vapour concentration is lower.   As a result of this  the moisture  concentration  within  the  bag  is regulated.            (No Figure number)
Patent CA-1327478-C (CA)
Inventor: SONOBE SABURO
IPC: B41N7/06
Filed: 1988-10-04
Granted: 1994-03-08
Abstract: Abstract of the Disclosure According to the present invention, the transfer roller 5 comprises a core roller and a matrix layer formed on the periphery of the core roller and made of rubber or resin.  The matrix layer has a number of semi-spherical depressions formed in its surface and also a number of hollow microspheres embedded in it.  As the matrix layer of the ink transfer roller is gradually worn as roller 5 is used, the hollow microspheres open in the surface of the matrix layer 11, thus forming new spherical depressions.  Hence, the spherical depressions are always distributed uniformly in the surface of the matrix layer, and hold a prescribed amount of ink.  The ink transfer roller therefore transfers ink in a desired amount onto the inking rollers of a keyless printing machines, in a uniform distribution all over the peripheries of the inking rollers.  The ink transfer roller, thus, achieves high-quality printing at low cost for a long time of period.

Title: Piezoelectric sensor
Inventor: WHITE CHRISTOPHER
IPC: F02M65/00
Filed: 1988-11-08
Granted: 1993-06-01
Abstract: ABSTRACT OF THE DISCLOSURE   A piezoelectric sensor adapted for incorporation into a high pressure fuel line employs a pair of piezoelectric transducer elements which are mounted in diametrically opposed bores of a main body. The body forms an axially extending fluid conduit.  The main body also has a deformable wall section adjacent the transducer elements. A conductor ring extends the circumference of the main body.  The transducer elements electrically connect with the ring so that a pressure pulse traversing the conduit deforms the wall section and produces a mechanical stress on the transducer elements to generate a voltage signal at the conductor ring.

Title: Determining fracture mode transition behavior of solid materials using miniature specimens
Inventor: MANAHAN MICHAEL P SR
IPC: G01N3/00
Filed: 1989-01-18
Granted: 1994-01-11
Abstract: ABSTRACT A method of determining fracture mode transition behavior (FMTB) of solid materials by using stress field modified miniature specimens.   The method is an  improvement  in  the  method  of  determining mechanical behavior information from specimens only so large as to have at least a volume or smallest dimension sufficient to satisfy continuum behavior in  all directions.    FMTB  of  the  material  is determined from the measurements taken during the loading of the specimen resulting in the formation of cracks and/or the further propagation of cracks in the miniature  specimen and/or fracture.  The specimens  are  provided with  grooves  that  induce additional stress field modifying stress components in the specimens during the test.  These additional stress components result in a desired stress state in  the  specimen  which  could  not  be  achieved otherwise.   The methods are useful in determining FMTB for the material, when the specimen thickness is  smaller than previously thought necessary  for valid FMTB determinations.

Title: Hybrid communications link adapter incorporating input/output and data communications technology
Inventor: HAAGENS RANDOLPH B
IPC: G06F13/38
Filed: 1989-01-27
Granted: 1993-07-06
Abstract: ABSTRACT OF THE DISCLOSURE There is disclosed a data communications link adapter providing flow of data control and status information between an input/output (I/O) Backplane and a fiber opticFrontplane. The adapter represents a melding of I/O channel extender technology and data communications technology: a dedicated processor handles link layer protocol, leaving to software only higher protocol layers; a flow-through architecture is provided by the adapter; a combination of windowing and handshaking are used; and a relatively short frame of sixteen bytes is employed. The adapter includes a backplane adapter portion which serves to interconnect host equipment, a processor portion dedicated to layer 3 (circuit operations), a protocol controller dedicated to layer 2 (physical layer) operations, a fiber optic interface portion dedicated to layer 1 (physical link) operations, and an arbiter portion which couples the processor to a data path connecting thebackplane adapter and the protocol controller. The arbiter controls data accesses that use a portion of the data path connecting the backplane adapter to the protocol controller and a data path between the protocol controller and the processor. A variety of data integrity measures are implemented on all data paths. The adapter facilitates data f low-through by buffering internal to the protocol controller, and has extensive data flow control features.
