G01N 3353

US Classification:

702 19, 702 31, 422 63, 422 67

Abstract:

To simplify the process of preparing microscope slides, an automatic staining apparatus is disclosed. The disclosed automatic staining apparatus comprises an electromechanical automatic staining device that is coupled to a personal computer system using an interface card. An autostainer control program runs on the personal computer system. The autostainer control program allows a user to simply program the automatic staining apparatus using simple commands entered in the graphical user interface. The autostainer control program includes several features that simplify the programming such as safeguards that ensure compatible reagents are being used; automatic buffer solution requirement calculator; and the ability to determine optimal staining procedure. The electromechanical automatic staining device includes features such as dual waste bins for hazardous and nonhazardous waste storage, an automatic dispenser cleansing system; and slide clip that minimizes capillary effect.

International Classification:

H01P 700

US Classification:

333219, 324318

Abstract:

A birdcage resonator has a pair of conductor rings separated from each other along a central axis and a plural number of axially disposed conductor rungs, which extend between the rings and are evenly spaced around the central axis. Each of the rungs has a sectional shape with thickness or a radial extension comparable to or greater than its width or its azimuthal extension. Measures of the width and thickness of the rungs may be determined by using them as parameters to calculate the values of Q factor from an analytical procedure to locate parameter value ranges corresponding to maximal Q. Geometric calculations for filling factor yield ranges of parameters providing for compromise parameter values. Saddle coils have been found to exhibit similar enhancement of Q with radially oriented conductor cross section.

International Classification:

H01F 706

Abstract:

Superconducting birdcage coil with low-pass and high-pass coil configurations are formed by using strips each with an elongated sapphire substrate with a layer of a high temperature superconductor (HTS) material grown in a wavy pattern over its entire length on one of its main surfaces. A low-pass coil is formed with a pair of ring elements made of an electrically conductive metal and a plurality of such strips arranged parallel to one another and interconnecting these ring elements at junctions which are spaced peripherally along each of the rings. At each of the junctions, the ring element and the HTS layer form a capacitance. A high-pass coil is formed by a plurality of such strips each with electrodes of the HTS material also grown at two end positions separated from each other on the other main surface of its sapphire substrates. These strips are arranged parallel to each other and sequentially around a central axis, each lying in a plane which includes the center axis. The electrodes and the HTS layers on mutually adjacent pairs of strips are closely in face-to-face relationship so as to serve as the ring part of a birdcage configuration containing capacitors.
