    摘要： An automatic chemistry analyzer includes a flow cell mounted so that flow through the cell and tubing connected to the cell is visible from the front of the housing. The electrolytes to the cell are removably plugged into the cell from their rear. The probe aspirating sample fluid into an injection cell is simultaneously washed by diluent and the diluent mixes with the fluid sample. Waste fluid from the flow cell is fed to a basin which then feeds under gravity to a waste drain. A ratio pump is formed by selected syringes which are band driven to deliver accurately prerequisite volumes of reagents to the flow cell. The solution ground to the system is on the inlet line for sample adjacent the entrance to the flow cell of fluid thereby minimizing electronic noise. Only two motive means are necessary, one to effect horizontal and rotational movement of the sample tray, and a second to effect vertical motion of a crane mounted probe operative between sample cups and an injection cell.

    摘要翻译： 一种自动化学分析仪包括一个流动池，该流动池被安装成使得流过细胞的流经和连接到该细胞的管可从外壳的前部看到。 电池向电池的后部可拆卸地插入电池。 吸入样品流体进入注射池的探针同时用稀释剂洗涤，稀释剂与流体样品混合。 来自流动池的废液被送入盆地，然后在重力作用下将其进料到排水管。 比例泵由选定的注射器形成，这些注射器是带式驱动的，以准确地向流动池提供前提体积的试剂。 接地到系统的溶液位于与流体流通池入口相邻的样品的入口管线上，从而使电子噪声最小化。 仅需要两个动力手段，一个用于实现样品盘的水平和旋转运动，另一个用于实现在样品杯和注射池之间操作的起重机安装的探针的垂直运动。

    摘要： An automatic chemistry analyzer comprises discrete sample cups about the circumference of a carousel. A motor selectively moves the sample cups towards and away from a target location where a probe is located for reciprocal vertical motion. The motion is timed for reaction with a sample cup so that when the sample cup is in position at the target location, the probe removes fluid from the sample cup. When the sample cup is moved from position, the probe aspirates fluid into an injection cell below the sample cup. A vertical motion only is imparted to the probe, while the sample cups move under the action of a single motor horizontally and laterally to define a rotational movement.

    摘要： A sample loading and unloading apparatus for an automated clinical instrument including a loading tray adapted to receive a plurality of sample carrying sectors. The apparatus further includes a sample carousel having a plurality of locations each adapted to receive sample sectors. The portion of the sample carousel nearest the loading tray defines a transfer position. The loading tray includes a transfer assembly for transferring a sector positioned at the transfer position from the sample carousel to the loading tray and simultaneously transferring a sector from the loading tray to the sample carousel. The transfer assembly includes a transfer spider which may be pneumatically raised to temporarily lift the sample sectors from the loading tray and the sample sector from the transfer position. The transfer assembly is rotated to a next index position and is lowered to thereby transfer the sample sector from the transfer position to the loading tray, increment sample sectors around the loading tray, and transfer a sector from a loading position on the loading tray to the transfer position.

    摘要： A data entry device durable enough to withstand the rigors of industrial type usage in which the electronic components are isolated from the external environment is described. The device comprises a molded elastomer keyboard matrix with thin stainless steel keypads. Embedded into the elastomer beneath the keys are small magnets. Solid state Hall-effect switches are mounted at a predetermined distance from the magnets and are separated from them by a magnetically permeable stainless steel sheet which forms part of the enclosure isolating the electronic components from the environment. Depressing one of the keys on the elastomer matrix moves its associated magnet toward the respective Hall-effect device, causing a change in current which may be sensed by other electronic components. Because of the elastomer material, the keys spring back when released.
