Patent CA-2064906-A1 (CA)
Title: Quantitation of nucleic acids using the polymerase chain reaction
Inventor: WANG ALICE M
IPC: C12Q1/68
Filed: 1990-08-20
Abstract: The present invention provides a method for determining the amount of a target acid segment in a sample by polymerase chain reaction. The method involves the simultaneous amplification or the target nucleic acid segment and an internal standard nucleic acid segment. The amount of amplified DNA from each segment is determined and compared to standard curves to de-termine the amount of the target nucleic acid segment present in the sample prior to amplification. The method is especially pre-ferred for determining the quantity of a specific mRNA species in a biological sample. Additionally, an internal standard is pro-vided useful for quantitation of multiple mRNA species.

Abstract: ANTI-ICING COMPOSITIONS HAVING ALKYLPHENOL    ETHOXYLATE NONIONIC SURFACTANT AND    ALKYLARYL SULFONATE HYDROTROPE       (D#81,192-F) Abstract of the Disclosure Anti-icing compositions, such as used on aircraft wing surfaces, may be thickened using a blend of a polyacrylic acid and a copolymer of polyacrylic acid with a vinyl monomer, where the copolymer acts as a thickener modifier. Additional advantages are obtained when a low molecular weight nonionic alkylphenol ethoxylate surfactant is used in conjunction with an alkylaryl sulfonate hydrotrope, as additives. This latter combination of additives gives anti-icing compositions with increased holdover times with no degradation of other properties. The compositions also contain an alkylene glycol component, such as propylene glycol, diethylene glycol and mixtures thereof. These compositions retain a high viscosity, even when diluted with water, and exhibit a highly pseudoplastic rheology indicating desirable flow off characteristics.

Inventor: MINAKAWA HIROSHI
IPC: H05B6/68
Filed: 1993-01-20
Abstract: A microwave oven includes a heating chamber, a turntable provided in the oven, a magnetron, a waveguide for guiding the microwave generated by the magnetron into the heating chamber, an electric field sensor provided at the inner wall face of the waveguide or the heating chamber, a metal reflector provided rotatably inside the waveguide for adjusting the impedance of a load at the heating chamber side by its rotation angle, and a circuit responsive to an output of the electric field sensor for controlling the rotation angle of the metal reflector.          The control circuit includes a first program for controlling the rotation angle of the metal reflector according to a first method within a predetermined time period from the start of operation of the microwave oven, and a second program for controlling the rotation angle of the metal reflector according to a second method different from the first method after elapse of the predetermined time period.  For example, in the first method, the rotation angle of the metal reflector is sequentially controlled so that the output of the electric field sensor is minimum, and in the second method, the rotation angle of the metal reflector is fixed to an average value of the rotation angle of the metal reflector of the first method.          The initial rotation angle of the metal reflector is determined so that impedance matching can be obtained when load of approximately 300-500cc calculated in water load is placed at the center of the heating chamber.

Title: Tank for electroanesthetizing fish
Inventor: SHARBER NORMAN G
IPC: A01K79/02
Filed: 1993-02-16
Abstract: TANK FOR ELECTROANESTHETIZING FISH                 ABSTRACT OF THE DISCLOSURE     Anode and cathode electrodes are placed at the upstream and downstream ends of an elongated tank containing fish to be electroanesthetized by applying an electric signal to the electrodes to create an electric field within the tank sufficient to induce petit mal in the fish.  By maintaining a flow of water in the tank from the end containing the anode electrode to this end containing the cathode electrode, the fish will tend to head toward the anode electrode and be subject to the largest voltage gradient induced by the electric field.  A barrier at each of the anode and cathode electrodes prevents contact by the fish to protect the fish against injurious electrical shock.

IPC: C12Q1/68
Filed: 1991-09-12
Abstract: Disclosed is a transformed yeast cell containing a first:,heterologous DNA sequence which codes for a mammalian G protein coupled receptor and a second heterologous DNA sequence which codes for a mammalian G protein a subunit (mammalian G.alpha.). The first and second heterologous DNA sequences are capable of expression in the cell, but the cell is incapable of expressing an endogenous G protein .alpha.-subunit (yeast G.alpha.).      The cells are useful for screening compounds which affect the rate of dissociation of G.alpha. from G.beta..gamma. in a cell.      Also disclosed is a novel DNA expression vector useful for making cells as described above. The vector contains a first segment comprising at least a fragment of the extreme amino-terminal coding sequence of a yeast G protein coupled receptor. A second segment is positioned downstream from the first segment (and in correct reading frame therewith), with the second segment comprising a DNA sequence encoding a heterologous G protein coupled receptor.

Filed: 1991-12-05
Abstract: A process for activating vulcanized waste rubber particles by treating the waste rubber particles with a rubber latex and a curing system and drying the treated waste rubber particles. The waste rubber particles are preferably treated with 1 to 4 % by weight of rubber latex (calculated as dry substance) and 0.5 to 3 % by weight of sulfur as vulcanizing agent, both being calculated on the waste rubber panicles. The treatment is carried out conveniently by mixing the waste rubber particles with the vulcanizing agent, adding the latex at a temperature of from 70 to 90°C and stirring the obtained mixture for 5 to 10 min. so as to evaporate the water. Also disclosed are processes for producing a rubber-like article by molding the activated waste rubber particles, whether or not mixed with a non-vulcanized rubber compound, while applying heat and pressure.

Title: Method and device for separating liquid/solid mixtures
Inventor: GUGGEMOS HORST
IPC: B01D25/12
Filed: 1992-01-29
Abstract: The invention concerns a method and device for separating mixtures of liquid and solid materials by squeezing out or filtering off the liquid component. The mixture is divided into a multiplicity of adjacent or consecutive portions which are simultaneously and jointly compressed or reduced in size by the action of an external compressive force which is substantially the same for all portions and which acts in the direction in which the portions are disposed next to each other, and is propagated through all the portions. The solids in the portions are retained as filter cake, while the liquid is squeezed out as filtrate. The invention calls for the filtrate squeezed out of the portions, or out of the filter cake formed in the portions/filter cakes, to be removed through the end faces of the portions as well as through at least the bottom and, if possible, also the top surfaces, and preferably also through the sides, and advantageously through the entire top surface of the portions or filter cakes, i.e. through the end and peripheral surfaces of the portions/filter cakes.

Title: Method and apparatus for separation and recovery of the components from foil-containing laminates
Inventor: KIRK THOMAS E
IPC: C22B21/00
Filed: 1993-09-20
Abstract: METHOD AND APPARATUS FOR SEPARATION AND RECOVERY       OF THE COMPONENTS FROM FOIL-CONTAINING LAMINATES                            Abstract Figure 1 A method for the separation and recovery of foils, in particular aluminum foils, and the other components in waste foil-containing laminates includes subjecting the waste laminates to agitation in a heated polyalkylene glycol polymer solution.  The thus heated mixture is cooled to permit density variations to separate the plastic and paper components of the waste laminate from the foil components therein.  The separated foil components can be recovered from the polyalkylene glycol polymer solution for recycle or other use. Using a polyalkylene glycol polymer solution permits recovery of the glycol polymer in a heated recovery tank to recycle the polymer to facilitate further foil separation while minimizing adverse effects on the environment.
