Abstract: A drug delivery apparatus and method for delivering a drug locally to internal body tissue. The invention contemplates positioning a drug delivery device in a body passageway or within body tissue and then selectively introducing a selected drug so that it is transported across a drug transport wall of the device for direct contact with the passageway wall or body tissue. A further aspect of the present invention involves treating a dilated vessel in the area of a stenotic lesion with a fixative or other drug to render the vessel biologically inert and to form a biological stent or prevent restenosis using specifically selected drugs. A still further aspect of the present invention involves treating a tumor or local or regional tissue mass with antitumor sensitizing agents, biological modifiers, antibiotics or other types of drugs by delivery of the drug to the tumor or tissue area directly or through the passageway wall.

Abstract: Analytical sensor devices incorporating a permselective medium immobilised as a continuous liquid or gel phase barrier between sample and detector. The barrier is electrically insulating, impermeable to charged non-lipophilic species, selectively partitions lipophilic species diffusing through it, and its selectivity can be controlled or optimised by pH adjustments. The preferred barrier form has the permselective medium (e.g. a lipid or ester) immobilised by incorporation as plasticiser in a polymer (especially PVC). The preferred detector is an electrode, especially of non-potentiometric type. The sensor can be used to detect components as such or indirectly by allowing them to react to produce other materials to which the detector responds (e.g. an ionic species or an ion concentration or activity change) and is also applicable to detecting neutral or small uncharged hydrophilic species, e.g. hydrogen peroxide -- especially that formed by enzyme action in the sensor or detector system. <IMAGE>

Abstract: An optical fibre package suitable for installation using a fibre blowing process comprises at least one optical fibre, an inner coating about said fibre, and an outer resin coating about said inner coating, said resin coating including a significant plurality of particulate inclusions at least 10  mu m across, wherein the concentration of the particulate inclusions is significantly greater at the outer surface of the resin coating than at the inner limit of the resin coating. The inclusions may be hollow glass microspheres or mica flakes. The relative absence of significant particulate inclusions at the inner limit of the resin coating improves the mechanical performance of the fibre package relative to similar known packages. The presence of significant inclusions at the outer surface of the resin coating tends, during a blowing process, to increase viscous drag effects and to reduce friction between the package and the duct into which the package is blown, thereby enhancing blowability. <IMAGE>

Abstract: Methods and compositions for use therein are described for expressing a polypeptide of interest in a seed cell as a fusion protein with an oil body protein. By this means, the fusion protein is targeted to the oil bodies of a seed cell. The oil body is easily separated from other cellular material following lysis of the seed cell, for example by using the partitioning/surface properties of the oil body. The fusion protein may be isolated for example by affinity chromatography using antibodies directed to the oil body protein. Where desired, the polypeptide of interest can be recovered by treatment of the fusion protein with for example a protease capable of recognizing a proteolytic recognition site in the oil body protein proximal to the N-terminus of the polypeptide of interest.

Abstract: The sampling process for measuring electrical resistivity by applying an electrical current via two emission electrodes (A,B) and measuring the potential between two measuring electrodes (M) comprises placing a probe containing a number of emission electrodes (A) and a number of measuring electrodes (M) in a drill shaft, with the number of emission electrodes being greater than the number of measuring electrodes. The emission electrodes are spaced at regular intervals and the measuring electrodes are placed centrally between the emission electrodes along the length of the probe. A fixed emission electrode (B) is placed "at infinity". The emission electrodes are supplied in turn and the potential between a pair of measuring electrodes is measured to obtain information representing the soil at the level of that pair of electrodes and at different positions in the soil relative to the probe, each position being related to one emission electrode. The above step is repeated for the different pairs of measuring electrodes to obtain information representing the soil at various levels. Also claimed are: (i) the application of the above process to controlling the injection of material such as concrete or grout into the soil; (ii) a probe for use in the above process; and (iii) a sampling device for carrying out the above process.

Abstract: A shaft clutch mechanism, and method and apparatus for its production are disclosed. The shaft clutch mechanism has an upper body folded into a polygonal cross section with a plurality of fingers, each finger attached to and extending from a flat section of the upper body. The shaft clutch mechanism is pressed on to one end of an inner nested element of a telescoping body and is placed inside an outer element where the fingers are slightly deformed, providing slight friction sufficient to hold the inner element in place, but still allowing it to slide relative to the outer element. The method and apparatus for producing the shaft clutch mechanism use a two stage press and a bending device to take a continuous strip of material to form blanks which then are bent to form the shaft clutch mechanism that is pressed on to the inner element of the telescoping body.

Abstract: A silicon carbide power MOSFET device includes a first silicon carbide layer, epitaxially formed on the silicon carbide substrate of opposite conductivity type. A second silicon carbide layer of the same conductivity type as the substrate is formed on the first silicon carbide layer. A power field effect transistor is formed in the device region of the substrate and in the first and second silicon carbide layers thereover. At least one termination trench is formed in the termination region of the silicon carbide substrate, extending through the first and second silicon carbide layers thereover. The termination trench defines one or more isolated mesas in the termination region which act as floating field rings. The termination trenches are preferably insulator lined and filled with conductive material to form floating field plates. The outermost trench may be a deep trench which extends through the first and second silicon carbide layers and through the drift region of the silicon carbide substrate. Since the termination region is formed from the first and second silicon carbide layers in the termination region, a time consuming, high temperature diffusion to form a floating field ring is not necessary. Rather, the same epitaxial first and second silicon carbide layers which are used to form an FET in the device region may also be used to form the floating field ring in the termination region.
