Title: Current Ratio Device and Toroidal Core Assembly Therefor
Inventor: SO EDDY
IPC: H01F38/30
Filed: 1992-11-04
Abstract: A current ratio device is used for forming a current transformer that can accurately scale down high currents to usable metering levels.  The transformer has associated circuitry that renders it capable of functioning not only with ac and a mixture of ac and dc, but also when dc alone is present in the primary winding.  The device employs a toroidal core and winding assembly that is cut along a plane containing the toroidal axis through a pair of diametrically opposite sections of the assembly that contain no windings, in order to separate the device into a pair of sub-assemblies that can be readily placed over a single turn primary, e.g. a busbar, without dismantling the same.   Once so placed, the sub-assemblies can then be clamped together again to reform the device and the winding portions externally connected to the circuitry, the latter being such as to avoid the accuracy of measurement being significantly effected by the unavoidable increase in core reluctance that will have resulted from the separation of the core assembly into two sub-assemblies.

Title: Optical sensor
Inventor: PEACOCK STANLEY J
IPC: G01N21/55
Filed: 1992-09-18
Abstract: An optical sensor senses the presence of an analyte in a fluid.  The sensor has a surface plasmon resonance-sensitive device (17) which reflects light from a light source (11) to a light detector (34). A ''pinhole'' aperture (33) determines the portion of the reflected light which is permitted to reach the light detector. On exposure to the analyte the device (17) responds so as to alter the intensity of the light reflected to the light detector (34).  The detector produces an output signal representative, for example, of the concentration of the analyte. The concentration is indicated by an indicating means (35).

Title: Rotor Blade Damping Structure for Axial-Flow Turbine
Inventor: SUZUKI ATSUHIDE
IPC: F01D5/30
Filed: 1994-10-11
Abstract: In an axial-flow turbine, at least one of front and rear side contact surfaces of shrouds (3a or 3b) of blades (1a or 1b) with respect to the turbine rotational direction is formed at certain angle with respect to a radial line connecting the rotor center and the contact surface.  The shroud (3a) of the blade (1a) of a first kind is formed in a trapezoidal shape converging radially outward in cross section taken in a plane perpendicular to the turbine axial direction, and the shroud (3b) of the blade (1b) of a second kind is formed in an inverted trapezoidal shape converging radially inward in the cross section.  Further, half of an angle (2a) between the front and rear side contact surfaces of the shrouds (3a or 3b) is made smaller than a static frictional angle of the contact surface. Since the shroud contact surfaces of two adjacent blades can be kept in pressure contact with each other under all operating conditions, a large dynamic stress reduction and superior damping properties can be obtained without producing excessive initial stresses at the blade airfoil and blade dovetail attachment portion.
