Abstract: This invention relates to a process of polymerization of unsaturated fatty acids, esters of unsaturated fatty acids, unsaturated hydrocarbons or unsaturated derivatives of these products by dielectric heating, as well as to the polymers obtained and uses of these polymers. It is claimed for the invention that the polymerization process is characterized by the fact that the reagent or reagent mixture is subjected to dielectric heating, that is, heating below frequencies ranging from around 30 GHz to around 3 MHz (radio or microwave frequencies) to effect polymerization. The process is conducted with or without catalysts; the reagents are fatty acids, fatty acid esters, plant or animal oils, hydrocarbons of the polyterpene or polyisobutene type, or derivatives of these products including at least one unsaturated substance, used either alone or in a mixture.

Abstract: Thermochromic laminates, which predictably vary their ability to absorb or reflect electromagnetic radiation, are provided. Laminates of the invention advantageously possess temperature trigger zones, that is, points or ranges of temperature, which function to decrease or increase the amount of electromagnetic energy, and particularly energy in the UV, infrared and visible ranges, that is reflected from the laminate, or absorbed as heat by the laminate and transmitted to an underlying structure. Laminates of the present invention can be provided in a variety of colors and temperature trigger points or ranges, and require no input of external energy except that of the impinging radiation. Laminates of the invention advantageously can be used in methods alone or combined with other materials such as roofing, siding, heat exchangers and other heat transfer materials and are therefore useful to control the temperature of an underlying structure or object.

Title: Method and apparatus for operations in underground subsea oil and gas wells
Inventor: BAKKE STIG
IPC: E21B7/08
Filed: 2000-10-23
Granted: 2010-08-17
Abstract: There has been explained a method and an apparatus for use in the advancing of a rotating motorised downhole tool for carrying out operations in an oil/gas well, especially in connection with the drilling and milling away of casing/casing sections in a well, which is to be abandoned and plugged by grouting with a cement mixture, which will then reach the formation wall surface where the casing/casing portion was milled away and removed. The rotating tool and its driving motor are indirectly suspended on coiled tubing at the free end thereof. As the platforms used for carrying out these operations are normally without rigs, it is advantageous to use coiled tubing to advance the tool/motor. However, coiled tubing cannot absorb a sufficient torque from the tool/motor. Therefore the tool with its motor is connected to a carriage, a so-called "rolling anchor" (1) which absorb torques that occur, and is connected to the end of coiled tubing through a swivel coupling (so that the torque will not be transmitted). Through the carriage (1) connected through the swivel coupling to the coiled tubing, a pull on the coiled tubing provides the tool and motor with advancing power for longitudinal movement, so that the advancing of the tool takes place from below upwards, whereby it has also been taken into account, that to the coiled tubing there cannot be supplied any particularly great downward forces.

Title: Bioabsorbable markers for use in biopsy procedures
Inventor: FISHER JOHN S
IPC: A61B19/00
Filed: 2001-01-26
Granted: 2010-06-01
Abstract: A bioabsorbable marker is placed in soft tissue such as breast tissue near a lesion during a biopsy procedure. If tests prove the lesion to be malignant, the market indicates the location of the lesion and the marker is removed surgically together with the lesion. If tests prove the lesion to be benign, there is no need to surgically remove the marker due to its bioabsorbability. One or more markers may be carried in an elongate, flexible marker carrier that is ensheathed within an elongate, flexible outer sheath. The flexible outer sheath is slidingly introduced into the proximal end of a biopsy needle until its distal free end protrudes from a port formed in the distal end of the biopsy needle. Retraction of the outer sheath relative to the marker carrier then exposes the marker carrier. The markers exit the marker carrier under their own inherent bias or an auxiliary bias is employed to eject them from the marker carrier. In a first embodiment, the bioabsorbable markers are hollow spheres made of polylactite acid. They are filled with iodine or other radiopaque material so that they are visible under X-rays and/or ultrasound. The radiopaque material is also bioabsorbable. In an additional embodiment, the hollow spheres are filled with an easily visible dye so that, when punctured, they provide a visible indication of a lesion's location. In another embodiment, they are filled with radioactive material and are inserted for therapeutic purposes in a lesion know to be malignant. Another embodiment provides solid markers, formed by pre-mixing together a radiopaque material and a bioabsorbable material. The solid markers may also include dyes and radioactive materials. In all embodiments, the markers may be spherical, cubical, pyramidal, pentagonal, or any other predetermined shape.

Abstract: a homogeneous assay for determining the deoxynivanlenol (DON) content in grains uses the technique of fluorescence polarization. A grain extract is prepared by shaking a crushed grain sample with water. A mixture is prepared by combining the grain extract with a tracer and with monoclonal antibodies specific to DON. The tracer is able to bind to the monoclonal antibodies to produce a detectable change in fluorescence polarization. The tracer is prepared by conjugating DON to a suitable fluorophore. The fluorescence polarization of the mixture is measured. The DON concentration of the mixtur e may be calculated using a standard curve obtained by measuring the fluorescence polarization of a series of DON solutions of known concentratio n.
