Title: Methode et appareil de transfert de donnees entre des systemes de gestion de bases de donnees heterogenes
Inventor: ADAIR JOHN G
IPC: G06F17/30
Filed: 1991-01-24
Abstract: L'invention établit le contexte dans lequel des données échangées entre des systèmes de gestion de bases de données relationnelles dissemblables peuvent être comprises et conservées de part et d'autre. Pour ce faire, l'invention établit des couches d'information descriptive qui isolent les caractéristiques machines, les niveaux des aides logicielles et les descriptions de données utilisateurs. Un traitement optimisé est obtenu en traitant les différents niveaux de descripteurs à des moments différents au cours du développement et de l'exécution des systèmes de gestion de bases de données. Une information descriptive minimale est échangée entre les systèmes de gestion de bases de données coopérants. Dans le cas de systèmes compatibles, la conversion de données est complètement évitée. Dans les autres cas, elle est réduite au minimum.

IPC: A47F7/00
Filed: 1991-06-12
Abstract: The easel comprises a flat, generally diamond-shaped member formed of resilient, non-scratching material of limited flexibility.  The member is scored to provide a line of weakness extending thereacross between its opposed oblique angle points.          When bent along the line of weakness, the member adopts a two-sided pyramidal form.  In this form, the member has rearwardly inclined,  load-supporting front edges and bottom edges.   The front edges form forwardly spaced and upwardly projecting hooks and slots close to their lower ends.   The hooks function to suspend,  retain and frictionally engage the lower edge of a generally flat item received in the slots to be displayed, such as a card, plate or the like.  The sides of the easel member can be  moved  closer  together  or  apart  to  vary  the  angle  of inclination of the load-supporting edges, thereby varying the angularity of the displayed item.  Frictional engagement between the hooks and the display item functions to prevent the side walls of the easel member from sliding apart when loaded.

Filed: 1991-10-15
Abstract: Filtration process and filters for use with materials such as, but no limited to, polymeric melts, utilizing a band (18) of a filter medium sealed in a housing (10) by sealing rollers (24, 26) to seal the polymeric material from leaking to the outside of the housing. In one embodiment, the sealing rollers make it possible to advance the filter medium through the housing continuously. In various embodiments, the filter medium can be advanced either by a take-up spool (32) or by driving the sealing rollers and the rate of movement of the filter medium through the housing can be controlled to maintain a constant pressure drop across the filter. Maintaining constant conditions through continuous advancement of the filter medium during filtration yields higher product quality and dimensional stability.

Abstract: A double-locking mount is disclosed for attaching an arrow quiver onto a bow. The arrow quiver has an elongated frame member for supporting an arrowhead protecting shield and an arrow shaft holder. A quiver mount, including a tapered mounting plate, is defined on the quiver frame. A mounting bracket which is mountable an a bow has a longitudinal tapered channel which is closed at one end, for receiving the tapered mounting plate on the quiver mount. The mounting bracket is oriented on the bow with the closed end of the channel at the bottom, so the quiver mounting plate cannot slide through the mounting bracket. A movable locking member is attached to the mounting bracket and has a finger latch which extends over and reversibly blocks the channel in the mounting bracket. The finger latch has a projecting portion which applies pressure to the quiver mount to hold it tightly in place in the mounting bracket. An elongated threaded locking member with a finger knob is threaded through a transverse aperture in the quiver mount and is engageable with a lock-receiving depression on the mounting bracket. When so engaged, the threaded locking member reversibly locks the quaver to the mounting bracket, protecting the user of the bow and the arrows in the quiver from injury should the movable locking member be accidentally opened. The threaded locking member also prevents noise generation caused by movement of the quiver mounting plate inside the mounting bracket.

Title: Method for manufacture of pre-cheese and natural cheese
Inventor: NAUTH KAISER R
IPC: A23C19/028
Filed: 1993-01-13
Abstract: The present invention is directed to a process for manufacture of pre-cheese that is capable of being converted into natural cheese having total solids in excess of 55%. The process includes the steps of removing moisture, salts and lactose from skim milk by a membrane process to provide a retentate having between about 70% and about 83% moisture, between about 0.7% and about 2.5% salts and less than about 1.8% lactose.        Cultures capable of metabolizing lactose to lactic acid are added to the retentate and the retentate is fermented until the lactose of the retentate has bean substantially converted to lactic acid. Sufficient lactose is provided to reduce the pH of the retentate to within the range of about 4.8 to about 5.6. The fermented retentate is then subjected to centrifugation to provide a concentrate having from about 30% to about 50% total solids. The concentrate is combined with a milk clotting enzyme, fat, salt and a mixed fermentate comprising a high digest casein fermentate, a lipolytic fermentate, a protease, a lipase and a proteolytic micrococcus to provide a cheese base. The cheese base is then fermented-to-provide a pre-cheese suitable for use in the manufacture of process cheese. In a further embodiment of the present invention, the pre-cheese is texturized to provide a natural cheese by working the pre-cheese in a mechanical mixer.

Abstract: A down-fired water heater has a top storage tank head portion with a central opening bordered by an upstanding annular flange.          Welded within this flanged opening is a generally pan-shaped tube sheet structure having an open top side, and a bottom side wall in which a spaced pair of openings are formed.  The open top ends of a U-tube immersion heating member, formed from a single length of metal  tubing,  are  upwardly received  and welded within  these openings.  During water heater operation, a top mounted shot-type fuel  burner  downwardly  injects  a  flame,  and  resulting  hot combustion gases, into one of the open upper ends of the U-tube.          A top mounted draft inducer fan, with an inlet communicated with the interior of the tube sheet structure, draws the combustion gases through the U-tube and into the tube sheet interior via the other open tube end, and then discharges the combustion gases outwardly away from the water heater.  The induced two-pass flow of combustion products through the tank interior very efficiently heats water stored therein and evenly distributes combustion heat along the height of the stored water.  In an alternate embodiment thereof, the top head portion is upwardly domed, and its flanged opening and the tube sheet structure are eliminated.  Openings are extended through a spaced pair of flattened areas on the top head portion, and the upper ends of the U-tube are inserted into and welded within such openings.

Title: Drill pipe
Inventor: MARTIN J SCOTT
IPC: F16L7/00
Filed: 1993-05-31
Abstract: DRILL PIPE     ABSTRACT     A drill pipe (10) is disclosed which includes a cylindrical pipe section (12), a box end (14), a pin end (16) and a hydraulic hose assembly (18) connected between the box and pin ends and extending within the cylindrical pipe section.  By passing drilling fluid through the hydraulic hose assembly (18), the interior surface of the cylindrical pipe section (12) is not exposed to the drilling fluid and does not need to be treated to prevent corrosion.  Further, the reduced volume of the hydraulic hose assembly (18) relative to conveying the drilling fluid through the interior of the cylindrical pipe section reduces significantly the waste of drilling fluid, allows the fluid to be pressurized more rapidly to initiate drilling operation, and limits fluid spill damage to the environment.  A rigid or flexible tube can replace the hose assembly (18), with the tube attached to the ends by threads, seals, press fits, O-rings or adhesives, or any combination thereof.
