Title: Data processing system and method for generating a representation for and random access rendering of electronic documents
Inventor: DEROSE STEVEN
IPC: G06F40/143
Filed: 1991-07-29
Abstract: ABSTRACT OF THE DISCLOSURE      A data processing system and method for generating a representation of an electronic document, for indexing the electronic document, for navigating the electronic document using its representation and for displaying the electronic document on an output device.  The system and method are used with electronic documents having descriptive markup which describes the content or meaning of the document rather than its appearance.  Such documents may be represented by a tree.  Each markup element defines a node or element in a tree.  The tree is represented by providing a unique identifier for each element and for accessing a descriptor of the element.  An element descriptor preferably includes indications of the parent, first child, last child, left sibling, right sibling, type name and text location for the element.  The document representation is used to facilitate navigation of the text for constructing navigational aids such as table of contents and full text indexing.  A document is also provided with a style sheet for specifying desired formatting characteristics for each type of element in the document.  To display the document, a suitable starting point is found on the basis of a selected starting point. The document is displayed beginning with the suitable starting point and the format characteristics for each element displayed are retrieved from the style sheet and applied to the text of the displayed element.

Title: Delivery catheter
Inventor: SCHATZ RICHARD A
IPC: A61B17/42
Filed: 1991-08-23
Abstract: A delivery catheter for introducing living matter into a body passageway or cavity of a female mammal comprises a hollow,  flexible,  substantially  tubular-shaped  collection chamber for holding the living matter.  An ejection port is formed adjacent to the distal end of the collection chamber and an actuator port is formed at its proximal end.  A guide tube having a lumen,  is positioned coaxially   within the collection chamber with the respective distal and proximal ends of the guide tube and the collection chamber joined together in fluid-tight sealing engagements.  In operation, the delivery catheter is inserted into the body passageway over a prepositioned guide wire.   More specifically, the delivery catheter receives the guide wire through the lumen of its guide tube to advance the delivery catheter along the guide wire.  Once the ejection port of the collection chamber is positioned at the desired site in the body passageway, fluid is introduced into the collection chamber through the actuator port to eject the living matter through the ejection port and into the body passageway.  The delivery catheter and the guide wire are then withdrawn from the passageway.

Title: System for efficiently exchanging heat or cooling ground water in a deep well
Inventor: HARRELL JAMES E JR
IPC: F24J3/08
Filed: 1992-02-13
Abstract: A novel ground water heat transfer system is provided for low cost and high efficiency heat pumps and includes a deep well filled with water. An insulating sleeve which is smaller than the diameter of the deep well is placed in the center of the deep well so as to separate the well water into two portions. A water pump is suspended preferably below the water level and pumps the water from inside the insulating sleeve to the space between the insulating sleeve and the wall of the deep well in a manner which eliminates the dynamic lifting head. In an open loop system the water from the pump is first pumped to an heat exchanger and returned to the space between the insulating sleeve and the wall of the deep well. In a closed loop system the water from the water pump is pumped directly into the space between the insulating sleeve and the wall of the deep well and the fluid supplied the heat pump is pumped through a closed loop which is submersed in the space between the insulating sleeve and the wall of the deep well.

Title: Apparatus and method for sedimentation based blood analysis
Inventor: MCKINNEY DAVID K
IPC: G01N15/05
Filed: 1991-04-17
Abstract: ABSTRACT OF THE DISCLOSURE            An apparatus and process for accurately determining settling data for the settling of erythrocyte cells from a plasma fluid in a test specimen of blood.  The apparatus includes a settling tube, a sensing assembly movably mounted proximate the settling tube.  Preferably an infrared emitter and detector are provided in the sensing assembly, and a control assembly is provided which senses data at a high rate and is responsive to the sensed data to sample or store the time at which sensed reflectivity exceeds a threshold level.  When the threshold is reached, data is sampled and the tracking head is moved by a very small step.  This process is repeated to enable tracking of the descent of the separation boundary between the erythrocyte cells and plasma fluid.  The apparatus senses changes in reflectivity of the erythrocyte portion of the specimen below and up to the separation boundary.  The apparatus and process also includes a scanning process to calibrate the reflectivity for each test specimen, the reflectivity also is measured immediately after moving the sensing assembly and recorded as a function of the position of the sensing assembly.

Abstract: PATENT APPLICATION PAPERS                            OF              CHARLES F. SCHULTZ          FOR:  FASTENER ASSEMBLY WITH INTEGRAL ANTI-ROTATION DEVICE                     ABSTRACT OF THE DISCLOSURE      A method of forming a fastener assembly, such as a stud or insert, having an integral anti-rotation device.  A cylindrical blank is first operated on such that an angularly, cup shaped flange portion is formed thereon.  The blank is then forced through a die, the flange portion to being forced to a position substantially parallel to the longitudinal axis of the blank and to simultaneously form serrations thereon thus producing an anti-rotation type device.  After thermal treatment, threads are form on the blank and the blank is then coated or plated in a conventional manner.  The length of the anti-rotation device is longer than the length of the mating counterbore in the parent material by a predetermined amount. The fastener is then screwed into the parent material cavity until the anti-rotation device shoulder bottoms in the counterbore. A drive tool places a downward force on the  fastener swaging or collapsing the serrated portion of the device and forcing it into the parent material thus locking the fastener against rotational or torsional forces.

Title: Minimizing gas separation in a mixer outlet
Inventor: NISKANEN TOIVO
IPC: D21C9/10
Filed: 1993-02-11
Abstract: ABSTRACT OF THE DISCLOSURE    A method and mixer are provided for mixing chemical (such as a gas like chlorine or oxygen) with a slurry (such as paper pulp having a consistency of about 1-16%) in such a way that separation of gas from the slurry at the discharge from the mixer is avoided.  Where the mixer housing has a radial discharge, the leading and trailing walls of the discharge (in the direction of circular and tangential movement of slurry within the main body housing of the mixer) present curved configurations to transition the slurry from circular/tangential movement to radial movement. The curvature of the configurations (which may be provided by inserts) does not exceed an angle of about 10 degrees at any point along them until radial flow is established.  Alternatively, the discharge may allow the tangential movement of the pulp in the main housing to continue by cutting off the original radial pulp discharge outlet, and welding or otherwise attaching a retrofit new discharge outlet to the main housing body similar to a pump volute with a gradually increasing cross-section.
