Filed: 1990-03-15
Abstract: A method of and kit for diagnosis of medical conditions by identification of specific DNA characterized in that DNA in a sample is subjected to initial amplification by the polymerase chain reaction (PCR) method using a first pair of primers specific to the target DNA and the amplified DNA so produced is further amplified by the PCR method using a second primer pair, one or both of which are different from either of said first primer pair and are specific to a sequence or sequences of the target DNA between the hybridisation sites of said first primer pair, one of the primers of said second primer pair being immobilised on a solid support or being provided with means for subsequent attachment to a solid support and the other of said second pair of primers carrying a label or being provided with means for subsequent attachment to a label, said amplification being followed by separation of said solid support carrying said amplified DNA and detection of label attached thereto, one or both of said means for subsequent attachment comprising a distal DNA sequence carried by the said primer which does not hybridise with the target DNA but has a selective affinity for a binding partner attached to either a solid support or a label.

Title: Metal matrix composite composition and method
Inventor: GUSTAFSON THOMAS W
IPC: C22C49/06
Filed: 1991-10-23
Abstract: METAL MATRIX COMPOSITE COMPOSITION AND METHOD Abstract of the Invention A new metal matrix composite of an aluminum based alloy and a ceramic, and a method of making it are provided.         In the preferred method, the ceramic is silicon carbide whiskers which are heated to an elevated temperature, generally in the range of between about 750°F and 2000°F.  An alloy, comprising by weight about 3 to 6 percent copper, about 0.5 to 5 percent magnesium and the balance essentially aluminum, is heated to melt the alloy.  The heated silicon carbide and molten alloy are mixed or intermingled.  The intermingled silicon carbide and molten alloy are then cooled at a rate sufficient to sustain supersaturation of the copper and magnesium in the aluminum down to a predetermined temperature.  The predetermined temperature is selected so as to permit precipitation of a strengthening copper-rich secondary metallic phase containing copper, magnesium and aluminum and consisting essentially of about 40 to 80 percent by weight copper, magnesium in an amount between about 5 and 30 percent by weight, and the balance essentially aluminum.  This forms a metal matrix composite having a silicon carbide phase, an aluminum-rich primary metallic phase and a copper-rich secondary metallic phase which has the desired composition.  The primary metallic phase can contain up to 10 percent of eutectic phase which is generally present as a coarse network or as isolated islands.          Preferably, cooling occurs immediately after the intermingling step and relatively rapidly to a temperature below about 550°F where precipitation of the secondary metallic phase occurs.         In a preferred embodiment, a metal matrix composite of the invention comprises a ceramic phase distributed substantially uniformly throughout the composite, and a metal phase which comprises an aluminum-rich primary metallic phase and a copper-rich and magnesium-rich secondary metallic phase distributed throughout the primary metallic phase. The secondary metallic phase contains copper, magnesium and aluminum and consists essentially of about 40 to 80 percent by weight copper, magnesium in an amount between about 5 and 30 percent by weight, and the balance essentially aluminum.  Preferably, the secondary metallic phase comprises cubical-shaped structures which are about 400 angstroms on a side.  Preferably, the ceramic phase comprises silicon carbide whiskers.

Title: Heat retentive server with phase change core
Inventor: WYATT W BURK
IPC: A47J39/02
Filed: 1990-05-15
Abstract: A heat retentive server, in particular a server base (100), for maintaining food or beverage in a desired temperature range for a period of time includes a non-metallic upper shell (110) and lower shell (120) which sealingly form a cavity between their inwardly facing surfaces. A heat storage member (140) inlcuding an encapsulated core (144) of phase change material is disposed in the cavity. As the server base is heated, the phase change material melts and stores heat as heat of fusion. When the core later cools, it undergoes a phase change from the liquid state to the solid state and imparts the stored heat to the server base.

Filed: 1992-01-15
Abstract: The invention is an extruder temperature controller for an extruder barrel. The invention includes means for determining an actual screw speed and has means for storing a plurality of screw speeds. Each member of the plurality of stored screw speeds has a corresponding stored temperature reset value. The extruder temperature controller has a means for comparing and selecting that compares the actual screw speed to each of the plurality of stored screw speeds and selects a default screw speed. The default screw speed has a smaller deviation from the actual screw speed than any other member of the compared, stored screw speeds.      The invention further includes a means for generating a control output driver signal to the heat exchange means. The control output driver signal is the corresponding stored temperature reset value for the default screw speed. The invention includes a method for controlling the temperature of an extruder barrel.      The adaptive reset value for a specific speed is derived for each extruder barrel zone for each profile table section of setpoints and parameters for a particular extrusion material and particular process.
