Title: Method for quantitative determination of mono- and diesters of polyethyleneglycols with higher fatty acids in their mixtures
Inventor: VASILEVA RAJNA S
IPC: G01N24/08
Filed: 1987-07-16
Abstract: The method is used in the determination of polyethylene glycol mono- and di-esters in natural vegetable oils by analysis of products obtained during oxyethylation of higher fatty acids with ethylene oxide. The method is easily implemented, and may be used without determining the molecular weights of the initial polyethylene glycols and fatty acids. According to this method, after recording the <1>H-NMR spectrum, a stoichiometric excess quantity of trichloroacetyl isocyanate is added to a pre-weighed sample for complete in situ reaction with the monoester until trichloroacetylisourethane is obtained. The <1>H-NMR spectrum of the resulting mixture is once again recorded. Quantitative determination of the monoester in mass percent is performed using the integrated signal intensities for the obtained trichloropolyurethane at 3.78, 4.43, and 8.76 ppm. The concentration of diester in mass percent is determined using the following equation: percent diester = 100 - percent monoester.

Title: Rapid screening mutagenesis and teratogenesis assay
Inventor: WEI CHA-MER
IPC: C12Q1/34
Filed: 1989-11-20
Abstract: RAPID SCREENING MUTAGENESIS AND TERATOGENESIS ASSAY      Abstract of the Invention A rapid, sensitive, and quantitative method and assay system using transgenic animal cells and adult or embryonic transgenic animals to rapidly screen compounds for mutagenic or teratogenic activity. Each cell from a cell culture, a differentiated tissue from an animal or an animal embryo contains a target gene and a reporter gene, both including an animal promoter/enhancer, a coding sequence and a transcription termination signal, so that they are capable of expression in animal cells.  The product of the target gene is capable of regulating expression of the reporter gene through interaction with a regulatory sequence in the reporter gene.  In the preferred embodiment, the target gene lacI (lac repressor) is coupled to the reporter gene lacZ encoding beta-galactosidase, which is easily detectable by cytochemical or histochemical procedures.  When the animal cell is exposed to a compound causing a mutation either altering expression of the target gene or altering the operator of the reporter gene, the reporter gene is expressed.

IPC: G10L15/12
Filed: 1990-03-28
Abstract: A speech recognizer, for recognizing unknown utterances in isolated-word small-vocabulary speech has improved rejection of out of vocabulary utterances.  Both a usual spectral representation including a dynamic component and an equalized representation are used to match unknown utterances to templates for in-vocabulary words.  In a preferred embodiment, the representations are mel-based cepstral with dynamic components being signed vector differences between pairs of primary cepstra.  The equalized representation being the signed difference of each cepstral coefficient less an average value of the coefficients. Factors are generated from the ordered lists of templates to determine the probability of the top choice being a correct acceptance, with different methods being applied when the usual and equalized representations yield a different match. For additional enhancement, the rejection method may use templates corresponding to non-vocabulary utterances or decoys.  If the top choice corresponds to a decoy, the input is rejected.

Abstract: Automatic dishwasher detergent composition is formulated as a linear viscoelastic, pseudoplastic, gel-like aqueous product of exceptionally good physical stability, low bottle residue, low cup leakage, and improved cleaning performance, Linear viscoelasticity and pseudoplastic behavior is attributed by incorporation of cross-linked high molecular weight polyacrylic acid type thickener. Potassium to sodium weight ratios of at least 1/1 minimize amount of undissolved solid particles to further contribute to stability and pourability. Control of incorporated air bubbles functions to provide the product with a bulk density of about 1.35 to 1.40 g/cc which roughly corresponds to the density of the liquid phase. Stearic acid or other fatty acid or salt further improve physical stability.
