    • A skid landing gear for a helicopter, in which the directional stiffnesses of the cross members of the skid landing gear have been de-coupled from one another, such that optimization of the longitudinal stiffness of the cross members may be performed independently of the optimization of the vertical stiffness and fatigue life of the cross members. In order to de-couple the stiffnesses in the skid type landing gear, two approaches are employed. In the first approach, the skid landing gear has non-symmetric-section cross members and/or distribution of different materials within the cross-section for de-coupling the vertical stiffness of the cross members from the longitudinal stiffness, such that placement of the ground resonance frequency may be optimized, while retaining the vertical stiffness properties essential for optimizing vertical energy attenuation and fatigue life. In the second approach, mounting devices are employed that provide compliance in selected directions, thereby de-coupling the directional stiffnesses.
    • 用于直升机的防滑起落架,其中滑行起落架的横向构件的方向刚度已经彼此脱离,使得横向构件的纵向刚度的优化可以独立于优化 横梁的垂直刚度和疲劳寿命。 为了解除滑行式起落架中的刚度,采用了两种方法。 在第一种方法中,防滑起落架具有不对称剖面的横向构件和/或横截面内的不同材料的分布,用于将横向构件的垂直刚度与纵向刚度解耦合,从而使 可以优化地面共振频率,同时保持垂直强度特性对于优化垂直能量衰减和疲劳寿命至关重要。 在第二种方法中,采用在所选方向上提供柔性的安装装置,从而解除方向刚度。

    • Apparatus is provided for processing an analysis slide in a chemical analyzer which is particularly suitable for performing both endpoint and rate analyses. The slide-processing apparatus comprises a slide transfer mechanism for selectively transferring analysis slides between an incubator and a read station. The incubator includes a temperature-controlled chamber having a rotor disposed in a horizontal plane therein comprising slide-holding members adapted to support each of a plurality of analysis slides at individual stations. Each of the individual stations may be selectively positioned to a transfer location wherein the slide carried by the rotor is accessible for removal. The slide transfer mechanism accesses the slide at the transfer location, removes the slide from the incubator, and delivers the slide to the read station. Following analysis at the read station, the slide is returned by the slide transfer mechanism to the incubator if the slide is being employed for rate analysis. If the slide is being used for endpoint analysis, the slide is discarded through a diverter portion of the slide transfer mechanism.
    • 提供了用于处理化学分析仪中的分析载玻片的装置,其特别适用于进行端点和速率分析。 滑动处理装置包括用于在孵化器和读取站之间选择性地传送分析幻灯片的滑块传送机构。 培养箱包括温度控制室,其具有设置在其水平平面中的转子,其包括适于支撑各个站处的多个分析载玻片中的每一个的滑动保持构件。 每个单独的站可以选择性地定位到转移位置,其中由转子承载的载玻片可被取走。 滑块传送机构在传送位置上访问幻灯片,从培养箱中移除幻灯片,并将幻灯片传送到阅读台。 在读站进行分析后,如果幻灯片用于速率分析,幻灯片将由幻灯片传输机构返回到培养箱。 如果滑块用于端点分析,则滑块通过滑块传送机构的转向部分被丢弃。

    • An apparatus and method for cauterizing biological tissue while providing isolation from surrounding absorbing tissue and fluid media. The device is comprised of a probe having a special window through which an infrared laser beam is directed to cauterize the biological tissue. The device is comprised of an infrared laser beam generator, a control circuit for controlling the intensity and duration of the laser beam and an articulated arm for directing the laser beam to the probe. The probe is comprised of a hollow, laser light guide tube having an infrared transparent window in its tip which permits the tip to be brought into contact with biological tissue such as vascular tissue to be cauterized while excluding the surrounding absorbing tissue from the effects of the beam. The probe may also include an adjacent endoscopic viewing tube and accessory tube to provide fluid, suction and optical illumination at the vicinity of the window.
