Abstract: Systems, methods, and machine-readable mediums are provided for collecting data. In one embodiment, a data collector system comprises a data requester interface to receive an information request from a data requester, the information request including a recipient and information collector parameters; an information request creator, communicatively coupled with the data requester interface, to create an create an email having an embedded information collector, the information request creator using the information collector parameters to define the embedded information collector; an email interface, communicatively coupled with the information request creator, to transmit the email to the recipient; and a data collector interface different than the email interface, the data collector interface to receive data associated with the information collector from the recipient.

Abstract: A chemical process sampler for use in monitoring the progress of chemical processing particularly suited for the handling of toxic, volatile, or otherwise dangerous substances. The sampler is characterized in the provision of multi-position valve structure for returning a contained sample to the processing vessel after use, thereby eliminating the need for separate disposal.

Abstract: An improved sight glass for use with sampling systems employed for testing the content of chemical reaction vessels. In addition to incorporating a check valve for preventing contamination of a vacuum source, the device incorporates provision for entrapping and draining sampled fluids in the event of leakage or fracture of the glass components thereof. This is accomplished by providing an inner transparent glass tube, the inner surface of which is chemically inert, and an outer concentric tube of synthetic resinous material which surrounds the inner tube and is less subject to breakage. The cylindrical interstice between the inner and outer tubes forms a drain for retaining leakage caused by fracture of the inner tube. A floating valve cooperates with a valve seat positioned longitudinally medially of the inner and outer tubes.
