Title: Improved apparatus and process for separating aluminium from a mixture of aluminium and aluminium dross
Inventor: STRATIGOS ANDREAS
IPC: F27D27/00
Filed: 1999-04-08
Abstract: An apparatus (14) for separating molten Aluminium from a mixture of molten aluminium and aluminium dross includes a table (16, 54) for supporting an insulated crucible (59, 75) containing the mixture of aluminium and aluminium dross. Electrical, mechanical or ultrasonic vibrators (70) or the like are provided to vibrate the table and crucible (59, 75). A frame (50, 52, 54) supports a rotatable paddle (18, 64), which can be lowered into the mixture in the crucible (59, 75) for stirring the mixture enabling simultaneous vibration of the crucible (59, 75) and stirring of the mixture. By virtue of that stirring and vibration, the aluminium droplets and particles of the dross coalesce to form larger droplets and gradually sink to the base of the crucible (59, 75). The aluminium can then be drained out into a bucket (20, 20a, 76). A screening means is disposed to substantially surround the crucible (59, 75) when it is supported by the table (16, 54). The screening means includes a door (72) to allow access to the crucible (59, 75) in one position and in a second position prevents access to the crucible (59, 75). A hood (80, 83) is provided at the top of the apparatus (14) so that the crucible (59, 75) is substantially fully enclosed. Gas burners (88, 90) may be used to retain heat in the crucible (59, 75) and contents.

IPC: C07K16/16
Filed: 1999-12-17
Abstract: IgE binding epitopes on allergens which induce allergic symptoms following surface contact, such as those associated with latex rubber and cat allergies, among others, can be blocked. Molecules which bind to these epitopes can be identified and synthesized and then formulated to coat or blend with the allergenic surface to prevent patient IgE from gaining access to the allergenic epitopes. In one embodiment, the molecules are antibodies or antibody fragments which selectively bind to the epitopes that elicit the allergic response. In another embodiment, the masking reagents are peptides which mimic antibody fragments and bind to the relevant epitopes on the allergens. In a third embodiment, the cDNAs encoding Fab fragments which bind to the relevant antigens are isolated and the Fab proteins encoded by these cDNAs are prepared.

Title: Polynucleotide sequencing method
Inventor: MCGINNIS MALCOLM D
IPC: C12Q1/6869
Filed: 2000-02-16
Abstract: Disclosed is a method for determining a sequence of one or more nucleotides in a target polynucleotide. In the method, a target-specific primer is contacted with a polynucleotide sample under conditions effective for the primer to anneal specifically to a primer-complementary region in one or more target polynucleotides, to form one or more target-primer hybrid(s), wherein each target-specific primer contains (i) a target binding segment and (ii) a mobility-reducing moiety which does not bind the target.  The hybrid(s) are reacted with a primer extension reagent in the presence of at least one labeled 3'-nucleotide terminator complementary to a selected nucleotide base-type, optionally in the presence of one or more extendable nucleoside monomers, under conditions effective to form one or more primer extension products which terminate with at least one labeled 3'-nucleotide terminator. The primer extension products are then separated electrophoretically in a sieving matrix under denaturing conditions such that smaller extension products migrate more rapidly than larger extension products, and the desired sequence information is determined.

Title: Method and system for simulating a hydrocarbon-bearing formation
Inventor: NIVARTHI SRIRAM S
IPC: E21B43/16
Filed: 2000-10-03
Abstract: The invention is a method for simulating one or more characteristics of a multi-component, hydrocarbon-bearing formation into which a displacement fluid having at least one component is injected to displace formation hydrocarbons (Fig. 1, item 5). The first step of the method is to equate at least part of the formation to a multiplicity of gridcells (Fig. 2, item 10). Each gridcell is then divided into two regions, a first region representing a portion of each gridcell swept by the displacement fluid (Fig.  3, item 16) and a second region representing a portion of each gridcell essentially unswept by the displacement fluid (item 17). The distribution of components in each region is assumed to be essentially uniform. A model is constructed that is representative of fluid properties within each region, fluid flow between gridcells using principles of percolation theory, and component transport between the regions. The model is then used in a simulator to simulate one or more characteristics of the formation.

Abstract: When a plurality of nodes determine the communication rate prior to point-to-point communication, there is reduced the difference in the throughput between a node which has determined a high communication rate and a node which has determined a low communication rate. For this reduction, a communication rate recording unit (11) of a slave node (1) records the best communication rate (the maximum communication rate) of the slave node (1). A communication rate setting unit (12) determines the communication rate between the slave node and the master node at the start of the data communication, and sets a control communication rate equal to or lower than the determined communication rate, on the basis of the maximum communication rate and the determined communication rate. A communication rate control unit (13) controls the communication rate by using a hold buffer (14) so that it may not exceed the control communication rate set by the communication rate setting unit (12).
