Title: Hair analysis method
Inventor: BAUMGARTNER WERNER A
IPC: C12Q1/37
Filed: 1989-11-28
Abstract: A method for the direct analysis of analyte in keratinized structures, e.g., hair, fingernails and toenails, which comprises preparing a mixture containing a low redox potential compound such as dithiothreitol or dithioerythritol, an enzyme suitable FOR the degradation of the keratin structure and a sample of the keratin structure; permitting the enzyme to at least substantially degrade the sample of keratin structure, and subjecting the mixture to analysis to determine the identity and amount of analyte in the keratin substance sample. To accelerate the method, cupric sulfate or sodium arsenite may be added to the mixture after degradation of the keratin sample. The enzyme may be a peptidase, endopeptidase or proteinase, with papain, chymopapain, and proteinase K being preferred for use in the invention.

Filed: 1989-12-21
Abstract: ABSTRACT OF THE DISCLOSURE           A control device for a movable article capable of permitting the movable article to give viewers much inter-est and surprise and impress viewers as if there is any communication between the viewers and the movable article. The control device includes a body formed in imitation of a loudspeaker, and a switch and a sound sensor provided on the body.  A movable article is arranged outside the device body which includes a motor electrically connected to the switch and sensor and a sound generating section and a mo-tion section carrying out various operations by turning-on of the switch and sensor.  When the switch is turned on, the motor is rotated in a positive direction, resulting in the sound generating section generating predetermined sound.  Also, when the sound sensor is turned on upon de-tection of sound, leading to the rotation of the motor in the opposite direction, the generation of sound from the sound generating section is stopped and concurrently the motion section carries out predetermined motion.
Patent CA-2008149-A1 (CA)
Inventor: SIEKIERKA JOHN J
IPC: C12N9/90
Filed: 1990-01-19
Abstract: A new homogeneous cytosolic binding (HCB) protein, having a specific binding activity of about 26 µg FK-506 per mg protein and a molecular weight of about 10-12 kilodaltons, reversibly binds the immunosuppressant FK-506 but not cyclosporine A (CSA). The protein is stable to heating at 56 degrees C. for 30 minutes retaining its FK-506 binding affinity, and has the (partial) amino terminal amino acid sequence: H2N-Gly-Val-Gln-Val-Glu-Thr-Ile-Ser-Pro-Gly-Asp-Gly-Arg-Thr-Phe-Pro-Lys-Arg-Gly-Gln-Thr-X-Val-Val-His-Tyr-Thr-Gly-Met-Leu-Glu-Asp-Gly-Lys-Lys-Phe-Asp (wherein X is undefined). The HCB protein is isolated from the -i-cytosol of mammalian tissues, preferably human neoplastic T-cell lines, e.g. Jurkat, and can be used in diagnostic and purification procedures involving FK-506 macrolide type immunosuppressants. The HCB protein also catalyses the cis-traps isomerization of proline-containing peptide bonds.
Patent CA-2008370-A1 (CA)
IPC: G06T9/00
Filed: 1990-01-23
Abstract: ABSTRACT OF THE INVENTION:          A system is described for reformatting halftone data for compression, wherein an original bilevel image is re-formatted to produce another bilevel image that allows vertical correlations to be recognized by the com-pression technique, thus improving compressibility dra-matically, with particular suitability for facsimile transmissions. In reformatting it is assumed that a se-lected halftone frequency H will satisfactorily describe an entire document, and each of successive sets of N consecutive lines are concatenated to form respective single lines. The thus reformatted lines have a clearer halftone periodicity offering greater correlation and permit more efficient coding by well-known standard bilevel compression algorithms (e.g., CCITT G3 (MR) or G4 (MMR)). For an image with unknown pattern frequency, a technique for readily estimating the frequency for use in reformatting the image is described.

Patent CA-2013089-A1 (CA)
IPC: B32B15/095
Filed: 1990-03-26
Abstract: ABSTRACT OF THE INVENTION The improved corrosion-resistant steel plate with an organic coating comprises a steel plate having a zinc or zinc alloy plate layer which is overlaid with a chromate film which in turn is coated with an organic resin paint film. The organic resin coat comprises an epoxy resin which is prepared by reacting with an isocyanate compound and has a dialkanolamine incorporated into its bisphenol A skeleton, and silica.  The dialkanolamine combines with a urethane-modified epoxy resin to provide satisfactory curability at low temperatures; at the same time, it combines with the silica to provide a satisfactory film reinforcing effect. The organic coat formed of this composition can be effectively cured at low temperatures and yet it will neither dissolve nor soften upon swelling under the action of the alkali that is generated during cationic electrodeposition at the interface between the electrodeposited film and the organic coat.  Thus, the organic coat has good paint adhesion, high corrosion resistance, as well as good workability and as-worked corrosion resistance and makes the steel plate suitable for use as an automotive part after painting.

Inventor: PITTENDRIGH BARRY R
IPC: A01N25/00
Filed: 1990-12-03
Abstract: A process is described for the control of the development of mosquitoes in a body of water, by spreading on the body of water a particulate carbohydrate compound. The carbohydrate compound may be a given compound that forms a hydrophilic gum-like layer once spread on the surface of the water. The gum-like layer prevents the development of mosquito in the larvae and pupae stages. It is also believed to inhibit the laying of eggs on the water surface by the female mosquito. The layer found is environmentally safe as the carbohydrates used are common in food products.

Title: Depth of cut adjustment for a portable circular saw
Inventor: SAUERWEIN WILLIAM D
IPC: B27B9/02
Filed: 1991-02-22
Abstract: In a portable circular saw depth of cut adjustment is effected by pivoting movement between a shoe (which supports the saw on a workpiece) and a motor and gear case housing (carrying the saw blade) about a pivot connection rearward of the motor and gear case housing.      Forward of the housing an upwardly extending arcuate depth slide, fixed to the shoe, slidably engages an arcuate depth guide carried by the motor and gear case housing. Towards the upper end of the depth slide, and in generally fixed relation to it, a clamping assembly selectively clamps the depth slide and depth guide together to establish a depth of cut adjustment setting. The essentially fixed relationship of the locking knob of the clamping assembly to the shoe mean that the operations of changing depth adjustment setting may be made without changing operator's hand positions on the saw. In addition, the fixed position of the knob in sawing operations mean that by design, suitably shaped, sized and positioned, it may be used as an auxiliary handle in guiding the saw in sawing operations.
