    • An adaptor that can be used with rotary fluid equipment will protect mechanical seals and/or packing material adjacent a seal cavity (18) of the equipment. The adaptor includes an annular body (30) with a central bore (32) adapted to receive a shaft (12) of the equipment. When used with mechanical seals the adaptor is receivable in the cavity at the entrance thereto and it has a portion which surface which effects contact with a complementary surface of the seal. When used with packing the adaptor fits within the cavity and defines an outboard extension in which the packing can be received. The bore defines two portions, one of which is close to the shaft (52) and another portion (54) which flares outwardly from the one portion towards the outboard end of the adaptor. Each bore portion has a spiral groove (56, 58) therein, which groove serves to redirect contaminant material contained in fluids surrounding the shaft away from the seal cavity.
    • 可与旋转流体设备一起使用的适配器将保护邻近设备密封腔(18)的机械密封和/或包装材料。 适配器包括具有适于容纳设备的轴(12)的中心孔(32)的环形体(30)。 当机械密封使用时,适配器可以在其入口处的空腔中接收,并且其具有与密封件的互补表面接触的表面的一部分。 当与包装一起使用时,适配器适合于空腔内,并且限定可以接收包装的外侧延伸部。 孔限定了两个部分,其中一个部分靠近轴(52),另一部分(54)从一部分朝向适配器的外侧端部向外张开。 每个孔部分在其中具有螺旋槽(56,58),该槽用于使围绕轴的流体中包含的污染物质远离密封腔。

    • Noninvasive, remote methods and apparatus for detecting early phases of neuro diseases such as the non-tremor phase of Parkinson's disease, dyskinesia, dyslexia and neuroatrophy, etc., are disclosed. Five words spoken either directly into a microphone connected to a local analysis system or remotely, as by way of a telephone link to a system for analysis of time and frequency domains of speech characteristics are representative of the presence of disease. The method includes the steps of transducing a set of unmodified spoken words or numbers into electrical signals which are bandlimited and amplified. These signals are analyzed in both time and frequency domains to detect and measure the manifestation of neurological disorders in the envelope of the time representation and spectral density of the words. Detection is carried out when the subject's body is in contact with neither a sensor nor an instrument, nor subjected to any other invasive means such as providing body fluids or breath, and without the need to perform any psychomotor functions.

    • Presented is a liquid filtering apparatus and method that overcomes the disadvantages encountered with prior bed filtration systems by providing a filtering apparatus that incorporates a super-buoyant filter medium having a specific gravity very substantially lower than that of the process liquid being filtered. This feature enables a majority of the medium to float on top of the process liquid. Due to the significant differences in specific gravity between the media and the process liquid, super-buoyant media produce a highly advantageous means of naturally, gravimetrically separating both clean and contaminated filter media and process liquid into separate “phases”. Under normal filtering operation, the filter media is contained within a filter housing by a bed support near the top of the filter housing, and particulate material is filtered from a process liquid that passes through the housing. To regenerate the filter media, the housing is drained and a nozzle creates a backwash spray that washes the particulate material from the filter media. During the backwash process, the filter media rises past the nozzle as the level of the backwash liquid in the housing rises, so that the entire filter media is regenerated.
    • 提出了一种液体过滤装置和方法,其克服了现有床过滤系统遇到的缺点,提供了一种过滤装置,该过滤装置结合了具有比正在过滤的工艺液体的比重更高的比重的超级浮力过滤介质。 该特征使得大多数介质浮在工艺液体的顶部。 由于介质和工艺液体之间的比重存在显着差异,超级浮力介质产生了一种非常有利的手段,将清洁和污染的过滤介质和处理液体重分离分离成单独的“相”。 在正常的过滤操作下,过滤介质通过靠近过滤器壳体顶部的床支架容纳在过滤器壳体内,并且颗粒材料从通过壳体的处理液体过滤。 为了再生过滤介质,壳体被排出并且喷嘴产生反冲洗喷雾,其从过滤介质洗涤颗粒材料。 在反冲洗过程中,当外壳中的反冲洗液体的水平升高时,过滤介质上升通过喷嘴,使得整个过滤介质被再生。
