IPC: G01N33/543
Filed: 1988-12-29
Abstract: A method for obtaining an actual linear standard curve in a sandwich type of immunoassay where a first antibody bound to an insoluble support and a second unbound labelled antibody complex with the antigen contained in a test sample to form an insoluble antibody:antigen:labelled antibody complex which is then detected. Unbound unlabelled first antibody and/or unbound unlabelled second antibody are added to the reaction mixture to divert excess antigen away from the desired end-product complex, thus rendering the antigen of interest the rate-limiting factor in the overall immunoreaction. This results in a pseudo first-order reaction which produces an actual linear standard curve.

Title: Titanium alloy based dispersion-strengthened composites
Inventor: NEWBY MARTYN ROHAN
IPC: B22F9/04
Filed: 1998-08-19
Granted: 2006-11-30
Abstract: Titanium based metal matrix composites reinforced with ceramic particulate are well known, based on a blend of titanium alloy powders with ceramic powders, e.g., aluminum oxide powders, utilizing a low energy ball milling process, followed by cold compacting and sintering to produce an appropriate composite. This prior art process is disadvantaged from the point of view that there are virtually no particles in the blend below the micrometer size range, which lack has a deleterious effect on the subsequent processing of the composite. This problem has been overcome by utilizing dry high energy intensive milling in the process, which has the effect of providing the necessary number of small particles below the micrometer size range as well as enhancing the reactivity of different particles with one another. In order to produce a titanium base alloy alumina metal matrix composite, titanium dioxide powder is blended with aluminum powder and subjected to dry high energy intensive milling until the separate particle phases achieve a size of 500 nanometers maximum. The intermediate powder product is then heated to form the titanium alloy/amumina metal matrix composite in which the ceramic particles have an average diameter of no more than 3 mu, and the oxide consists of more than 10% and less than 60% by volume fraction of the total composite. The composites have extensive application to tough and strong engineering alloys.

Filed: 1990-09-21
Granted: 2001-02-13
Abstract: A borehole mining process fox recovery of petroleum from unconsolidated heavy oil formations is disclosed. The process consists of drilling a borehole in the unconsolidated heavy oil reservoir, which is formed from sand particles aggregated by heavy oil, and positioning a casing and a first and second tubing string within the borehole. At least one nozzle is positioned on the lower end of the second tubing string and is oriented for fluid emission generally radially outwardly from the second tubing string. Fluid is then flowed downwardly through the second tubing string and outwardly through the nozzle, thereby eroding a cavity in the reservoir and forming a slurry consisting of the fluid, the heavy oil, and the particles from the reservoir. The slurry is flowed upwardly through the annulus between the first and second tubing strings to the upper end of the borehole for recovery of the heavy oil.

Abstract: A method is disclosed for the production of metal oxide ceramic membranes of very small pore size. The process is particularly useful in the creation of titanium and other transition metal oxide membranes. The method utilizes a sol-gel process in which the rate of particle formation is controlled by substituting a relatively large alcohol in the metal alkoxide and by limiting the available water. Stable, transparent metal oxide ceramic membranes are created having a narrow distribution of pore size, with the pore diameter being manipulable in the range of 5 to 40 Angstroms.

Title: Automatic function selecting multimeter
Inventor: MELDRUM GLEN A
IPC: G01R15/09
Filed: 1990-11-27
Granted: 1994-02-08
Abstract: Abstract of the Disclosure A digital multimeter having automatic function selection capability includes a signal type detector and an analog-to-digital converter formed as an application specific integrated circuit. The signal type detector has a comparator circuit that compares the analog input signal to be measured with predetermined thresholds and stores the resulting values, which are related to the type of analog input signal, in a memory that is also a part of the signal type detector. A controller executes an automatic function selection program that causes the controller to read the stored values and generate a corresponding function code, which causes an analog-to-digital converter to be configured to perform an appropriate conversion function on the analog input signal. When a change in the type of analog input signal is sensed, the controller aborts the present measurement cycle and proceeds with a next measurement cycle in which the changed analog input signal is measured. The controller also produces a changing alert signal to indicate that a change in signal type has occurred.
