This invention relates to a device for a continuously operated dilution of a slurry sample, through which device the slurry sample is fed directly into a continuously operated optical analyzer, such as a grain size analyzer. When a telephone exchange detects that a called number is changed based on a subscriber information database, the telephone exchange sends a prompt message asking for sending a telephone number notification request to a calling telephone. The pull section includes a protrusion extending from the fastener engagement end, thereby extending the length of the pull section. The integral assembly includes a predetermined, previously installed charge of fluid that extends from the transducer, through the corresponding pressure lumen and into the interior volume of the sensing balloon. The time stamp clock reference has a frequency derived from the single crystal clock reference by digital counter means. The capability messages define terminal capabilities such as human machine interfaces.
