Abstract: Photocurable restorative materials for making dental restorations usually are highly filled with fillers such as amorphous silica, quartz or glass powder having limited translucency to curing radiation. Thus the underside of the restoration may not become adequately photocured. Better curing at the underside is achieved by applying a coating of fluorescent or reflective material beneath the restorative material. When exposing the restorative material to radiant curing energy, the resulting fluorescence or reflectance by the coating enhances the degree of cure of the underside of the restoration.

Abstract: The invention relates to a laboratory centrifuge with a drive unit having a motor, with a rotor and with a device for the detection of an unbalance occurring during the operation of the centrifuge, the device having an unbalance element and a switching element, the unbalance element being in a fixed assignment to the drive unit and following the unbalance movement directly in the case of unbalance and carrying out a relative movement with respect to the switching element, a switching signal being generated after a predetermined threshold value of the relative movement has been exceeded, which signal triggers a control unit which interrupts the power supply to the motor. The object which arises here of maintaining a simple and economical but yet reliable device for detecting an unbalance in all speed of rotation ranges of a centrifuge, which is adjustment-friendly and immune to faults and which can simultaneously detect in all spatial directions both unbalance movements which are produced with large deflections of the drive unit as well as those which are produced at high acceleration values, is achieved in that the switching element forms together with the unbalance element a unit which is mounted on the drive unit, the unbalance element having at least two elements arranged at a distance from one another which form a signal transmission route, and in that the switching element is a switching fluid which is arranged in a container and is freely movable within the intermediate space determined by the signal transmission route in a surrounding fluid and the transmission route opens and/or closes, generating the switching signal, in which case the switching fluid and the surrounding fluid have different specific densities and cannot be mixed with one another. At least one of the two fluids is a liquid.

Abstract: The invention relates to a method for producing separated fat and water images of at least one layer, in which method a multiplicity of sequences acts on the layer in the presence of a stationary magnetic field. Each sequence comprises at least a first high-frequency pulse followed by a phase-coding gradient and a measurement gradient during which the nuclear resonance signal produced in the layer is measured. Groups of sequences are formed with a time position, varying from group to group, of the measurement gradient and/or of any further high-frequency pulse and the number of sequences per layer is twice as large as for the production of a similar image without fat/water separation. For this purpose, the phase-coding gradient is varied in steps from sequence to sequence, the phase angle of one high-frequency pulse of the sequence is varied from step to step by the same amount in each case, and a fat and water image (F,W) is produced from the nuclear resonance signals by a 2D Fourier transformation.

IPC: A61B5/055
Filed: 1990-08-09
Abstract: A substantially continuous image, recording motion of a portion of a sample, is provided by first NMR exciting, through use of a rotating-gradient (p) pulse signal, a relatively narrow cylindrical region, typically with diameter less than 1 inch, of magnetization intersecting the sample to be imaged and then acquiring the NMR response signal thus excited, in the presence of a readout gradient oriented along the length of the cylindrical excitation beam and establishing position thereon. A Fourier transformation of the acquired data allows display of a real-time record of the profile of the sample along the axis of the cylindrical probe beam. The cylinder-beam axis can be oriented in an arbitrary direction by proper mixing of the excitation and readout gradient fields; use of three orthogonal gradients in a Cartesian coordinate system is presently preferred. Spatial offsetting of the cylindrical beam, from the center of the static magnetic field of the NMR imaging system, to any specific location within the system's imaging volume, can be obtained by frequency modulation of the p pulse RF waveform.

Abstract: A device protects an electric load, such as a motor, from excessive current levels. The current flows from a source to the load through a switch and a primary winding of a current sensing transformer (21, 22, 23). The voltage across a secondary winding of the current sensing transformer is rectified (30) to produce a voltage which is measured to determine the level of current through the load. The voltage across the secondary winding also powers components of the device (16). In a first mode of operation, current from the secondary winding is applied to charge a power supply capacitor (35). In a second mode of operation the level of the rectified voltage is sensed (60, 73, 74, 80, 89) to produce a sample of the level of the current flowing through the load. From this sample the change in temperature of the load since a previous sample is calculated and used to derive the present load temperature. When the present load temperature exceeds a defined threshold level, the switch is opened to disconnect the load from the electricity source.

Abstract: Independent figure elements (12, 13) in an object image (11) are correlated with a reference image (Fig. 3). Both images include independent elements (12, 13, 22, 23) which are not interlinked with each other. The method comprises defining a relative coordinate system (X′, Y′) in an image plane for the reference image (Fig. 3) and the object image (11) on the basis of centers of gravity of two distinctive independent elements (12, 13) which are identified with values indicative of features such the perimeter and area of the elements; and collating pairs of independent elements between the reference image and the object image on the basis of the relative coordinate system (X′, Y′). The object image (11) is initially formed in the field of view of a video camera, the independent figure elements (such as 12, 13) being thereby located in the coordinate system (X, Y) of the camera field of view, and therefore not necessarily in the same positions in the system (X, Y) as corresponding independent figure elements of a stored reference image.
