Abstract: A method of providing accelerated thermal fatigue testing of an engine component, comprising: (i) impinging one or more torch flames directly on a selected area of the test specimen (i.e. metallic engine cylinder head) to heat such area to a critical test temperature that exceeds the normal maximum loading temperature of the specimen in normal use by about 10-25%, and holding such temperature for a period of .01-2.0 minutes;  (ii) at the end of the holding period (i.e. Water jet water in head jacket, or air in ports) quenching the heated area of the test specimen to a temperature that is about 75% below that of the normal maximum loading temperature and holding such quenching temperature for about 1-3 minutes; and (iii) repeating steps (i) and (ii) until a crack is induced in the test specimen while recording the history of temperature and time involved in such repeated steps.          An apparatus for accelerated thermal fatigue testing, comprising a system having:  (a) a heating enclosure supporting a metallic cylinder head; (b) a plurality of torches extending into such enclosure for impinging flames on selected areas of the head, the torches carrying a combustible mixture of air and fuel in a ratio of about 10 to 1, that can provide a flame that heats the areas from room temperature to a temperature of at least 250°C in a period of less than 1 minute; (c) a plurality of quenching nozzles with at least one nozzle associated with each area for directing quenching fluid thereonto for a selected time interval; (d) controlled means for cycling the operation of the torches and nozzles, wherein a cycle can be repeated which cycle consists of quickly heating the selected areas of the head to said temperature and holding for a period of .01-2.0 minutes at the end of which time a nozzle administers quenching fluid that rapidly reduces the head temperature by at least 200°C for a period of 1-3 minutes.

Title: Process for monitoring and detecting small molecule - biomolecule interactions
Inventor: MANEZ ANGEL
IPC: G01N29/036
Filed: 1999-05-05
Abstract: Small molecules (molecular weight less than about 2800) are screened for interaction with biomolecules by contacting a solution containing the small molecule with immobilized biomolecules under test, and generating acoustic waves in the solution using an acoustic wave device. Interaction of the small molecules with the immobilized biomolecules causes a change in frequency of the acoustic waves, which can be detected and analyzed electronically to monitor the interaction.
Patent CA-2271232-A1 (CA)
Inventor: ESMON CHARLES T
IPC: C07K19/00
Filed: 1997-11-07
Abstract: Modified Protein C molecules have been made which substitute the gamma carboxylglutamic acid (Gla) region of another Vitamin K dependent protein, most preferably prothrombin, for the native region of the Protein C. A modified Protein C molecules has been made which substitutes the gamma carboxylglutamic acid (Gla) region with the corresponding region of prothrombin. The modified or chimeric protein C has advantages over the wild-type protein C since it is less sensitive to inhibition by some natural antibody inhibitors of protein C (which would otherwise decrease the ability of the protein C to act as an anticoagulant) and which do not need the same cofactors or same amounts of cofactors, and can therefore be effective in patients with lowered levels of the cofactors such as protein S or the lipids present in elevated levels in platelets such as phosphatidyl ethanolamine (PE). The anticoagulant activity of the chimera was tested in normal and factor V Leiden plasma. The chimera was approximately ten times more effective in inhibiting factor V Leiden plasma clotting.

Patent CA-2275489-A1 (CA)
Inventor: MOLONEY MAURICE
IPC: C07K19/00
Filed: 1997-12-05
Abstract: A method for the separation of a target molecule from a mixture is described.  The method employs oil bodies and their associated proteins as affinity matrices for the selective, non-covalent binding of desired target molecules. The oil body proteins may be genetically fused to a ligand having specificity for the desired target molecule. Native oil body proteins can also be used in conjunction with an oil body protein specific ligand such as an antibody or an oil body binding protein. The method allows the separation and recovery of the desired target molecules due to the difference in densities between oil bodies and aqueous solutions.

Title: Power generation method and power generating apparatus
Inventor: IIJIMA MASAKI
IPC: C10L1/00
Filed: 1997-12-17
Abstract: A method and an apparatus for power generation, by which high-efficiency power generation is achieved by utilizing a boiler-oriented fuel such as inexpensive coal, heavy oil and waste plastic, and by further utilizing a gas-turbine-oriented fuel in some cases, without exerting bad effects on the environment, at low equipment cost. In the apparatus, first, the boiler-oriented fuel is separated into a distillate and a residue by partial processing. The distillate (in some cases, with a gas-turbine-oriented fuel) is supplied to a gas turbine to generate electric power.      Further, a combustion exhaust gas discharged from the turbine is supplied to a boiler. Then, the residue (in some cases, with a boiler-oriented fuel) is burned to obtain steam.      Further, electric power is generated by the steam.

Title: A method of processing seismic data signals
Inventor: GEHRMANN THOMAS
IPC: G01V1/28
Filed: 1998-02-18
Abstract: A method is disclosed for characterising the subsurface levels of the Earth with a greater degree of accuracy than hitherto. Seismic data samples are migrated and stacked, for example according to known techniques and then spectrum analysed. The spectral analysis is applied to a feature of the subsurface and, for example, a particular layer bounded by a pair of horizons would be subject to volume reflection spectral analysis. The analysis is carried out using an orthogonal base by defining the reflection signals in terms of coefficients to a set of orthogonal polynomials. Additional seismic characteristics or attributes may be directly calculated from the polynomial coefficients. These coefficients represent the characteristics of the layer to a high degree of accuracy and may be compared with spectra derived a priori (for example synthetic spectra or previously characterised spectra) to further assist in analysis of measured seismic data.
