    摘要: Typical apparatus as shown in FIGS. 1 and 12 for indicating the relative positions in a given direction between a reference point (24,59) and a test point (29,68) spaced therefrom and movable relative thereto is useful for measurement of the magnitude and direction of static or dynamic torque in a shaft (8). Overlapping transparent reference (20,60) and test surfaces (25,61), either parallel disks (60,61) or coaxial cylinders (20,25) each having a relevant portion covered with a plurality of equally spaced lines oriented predominantly normal to the given direction and at an angle to each other, produce moire fringes (30) when illuminated (14,15). One of the surfaces (25,61), being flexible, is connected to the shaft (8) so as to flex in response to torque between the reference point (24,59) and the test point (29,68), causing a change in the angle between the lines on the two surfaces (20,25;60,61), and thus of the spacing (D) (FIG. 3) of the moire fringe bands (30), which is optically detected (17) and converted, as shown in FIG. 4, to an electrical signal (42) to control power applied to the shaft (8).

    摘要: High-throughput centrifugation of batches of samples is achieved by dividing a single centrifugation run of a batch of samples into two or more staggered, discrete spins with fewer samples and in which the availability of centrifuge slots for loading or unloading of samples and the subsequent delivery of experimental results can be enhanced. The methodology is particularly useful in situations where multiple samples need to be processed rapidly, for example, as part of a STAT blood typing program in urgent care facilities prior to blood transfusion.

    摘要: An improved Electrohydrodynamic (EHD) nozzle particularly suitable for a handheld pulmonary aerosol inhaler increases the consistent and efficient dispensing of therapeutic liquids by reducing or eliminating wetting through shielding of discharge electrodes. Some versions further eliminate wetting while enhances neutralization of the aerosol through presentation of a corona wind of ions annularly surround the aerosol. Incorporation of improved liquid distribution with consistent pressure drops to each EHD nozzle tip allows horizontal dispensing, and by using dielectric nozzle tips with low surface energy to thereby avoid wicking between dispenses and to advantageously reduce achievable particle size when dispensing. Some versions feature enhanced snap-fit assembly and other manufacturability advantages. One of the unique features of the EHD nozzles is achieved high dose rate (microliters/minute) with low wetting and small particle size (1.0-5 microns), although these properties tend to be mutually exclusive. Furthermore, these attributes are incorporated into a conveniently small, handheld device.

    摘要: A surgical probe wherein a heat sterilizable and reusable detector component is combined with a disposable handle and cable assembly. The reusable detector component incorporates a detector crystal and associated mountings along with preamplifier components. It is formed having a positioning shaft extending therefrom to a contact supporting surface carrying a pattern of electrical contact surfaces. Two orientation bosses are formed with the positioning shaft. The disposable handle employs an insert member having a receiving cavity. The electrical contact carrying tip of the shaft engages an elastomeric seal and moves into electrical engagement with a pattern of electrical contacts mounted within the handle in conjunction with a permanently affixed flexible cable.
