IPC: G01N33/543

Abstract: Enzyme-linked immunosorbent assay (ELISA) is perhaps one of the most widespread assay methods used extensively in the field of immunology. This assay works on the basis of known amounts of antigens or antibodies adhered onto a solid surface made of polystyrene. The polystyrene-made wells are opened at only one side and each well is eight mm in diameter, ten mm in depth and holds up to a maximum of 300 µL, in volume. Every 8 or 12 wells joins together to form a 96-well or a 48-well combination unit. The inner wall of each well is smooth with a transparent flat base. Generally, approximately 100 µL of known antigens or antibodies is added to each well occupying one-third of the well.   Known amounts of antigens or antibodies are allowed to adhere onto the polystyrene surface at a specific temperature for over 10 hours. This process is often known as "coating". Following this, protein solutions at high concentrations or solutions with concentrated proteins and glucose are allowed to further adhere onto the polystyrene wells to ensure maximum occupancy of the well surfaces. In addition, this second coating offers better protection on the activity of the antigens or antibodies. This second process is termed "blocking".   The commonly used enzyme (horseradish peroxidase) can be linked either to the antigens or the antibodies, but in either case the solid-phase reactant is unlabeled.  ELISA can be made quantitative by setting it up as a competitive inhibition assay in which free or unknown amounts of antigens (or antibodies) in samples compete with enzyme-labeled antigens (or antibodies) for binding sites on the polystyrene solid phase coated with known amounts of antigens or antibodies. Following appropriate washings, the concentration of enzyme bound to the immune complex is estimated by the addition of its substrate that changes colour when the substrate is acted on by the enzyme.  This highly-specific immunoassay has thusfar become one of the most popular immunoassays in immunology and immunology-related studies.

Title: Job token printer assignment system
Inventor: SCHWARZ JAMES K JR
IPC: G06F13/00
Filed: 1998-12-04
Abstract: A client provides a job ticket token to a print server, which contains the profile of a print job to be printed. The print server parses the job ticket token, determines an appropriate printer for the print job, and returns a selected printer token to the client, that includes the network address and name of the selected printer. The client then sends the print job, accompanied by the selected printer token, to the appropriate printer. In this way, the print job is assigned to a proper printer for the print job by the print server. One advantage of the job token printer assignment system is that the print server does not see the print job, but merely the job ticket token of the print job. Accordingly, the print server does not have to spool a large print job, but merely has to identify the characteristics contained in the job ticket token, and assign the print job to an appropriate printer. Further, because the print job is not transferred to the print server, but merely from the client to the printer, the network does not have to carry the print job twice.

Title: Low volume fraction metal matrix preforms
Inventor: LO JASON SIN HIN
IPC: C22C49/00
Filed: 2000-08-31
Abstract: A process for making a low volume fraction preform for a metal matrix composite, wherein the metal is typically magnesium, aluminum and alloys thereof , and the reinforcement comprises either whiskers, fibres, tow or particulate, typically chosen from silicon carbide, graphite, carbon, silica, alumina, titanium diboride, boron nitride and boron carbide. The resulting preform has sufficient strength both to be handled, and to be infiltrated with liquid metal, for example by a squeeze casting process. A particular selection of binder material and sacrificial fillers is used to make the preform. In the first step, the reinforcement is mixed with a binder, and with sacrificial fillers, to provide a castable slurry which is then placed in a mould, to provide a green cast preform. In the second step, the green casting is dried, to remove any water and/or solvent remaining from the castable slurry. In the third step, the green preform is fired at a relatively low temperature, to burn off the sacrificial fillers. In the fourth step, the green preform is fired at an elevated temperature sufficiently high to sinter the binder to bond the reinforcement together. In the third and fourth steps particular combinations of temperature and time are used to ensure decomposition of the sacrificial fillers, followed by firing of the binder to sinter it and thus bond the preform together without destruction or cracking of the green preform. This process can also be used to provide low volume fraction preforms, so that the metal matrix composite contains less than about 8% by volume of whiskers, or less than 15% by volume of particulates.
