They probably dates to the late 1960s or early 1970s. The films provide an overview of the services and products offered by MRI, a company specializing in meteorological research and equipment. In an era when environmental monitoring was becoming more and more important, MRI offered air quality and emission measurement services. This included innovative use of instrumented aircraft to fly through smokestack emissions, as well as source monitoring. 00:00: Introduction to MRI and its standard meteorological system. Visual: a female operator uses a telephone switchboard. 0:30: MRI receives inquiries from customers about meteorological measuring equipment. An applications engineer discusses requirements and prepares a proposal. MRI's standard meteorological system can be operational on-site within 30 days. Visual: man on the phone, MRI computer system being assembled with ¼" tape drive / data recorder. 2:00: The system includes components like signal conditioners, analog recorders, digital data loggers, and magnetic tape recorders. Various sensors measure temperature and wind. The Model 1022 wind sensor is highlighted for its ease of installation. 3:00: The instrument shelter is skid-mounted, equipped with a heater and air conditioner, and can be installed on a cement slab. A 60-meter tower is shown being assembled. This is provided for conventional installations, meeting FAA specifications without needing painting or lighting. 4:30: Teletype machine in action. 5:00: The process of modifying and quality-checking the transmuter for additional parameters and lightning protection. Preparation of the shelter for air freight and assembly on-site, including installation of air conditioning and electrical wiring. Woman types on an IBM electric typewriter, typing a sales order. 5:21: circuit boards are assembled in house by a technician using a soldering iron. 7:00: Weather station assembly. Final checks and shipping preparations for the tower and auxiliary power supply options. MRI's capability to install a standard meteorological system within 30 days from order receipt. 8:55: Brief break in the film. 10:00: A factory smokestack belches white emissions into the sky. A small aircraft with instrumentation aboard flies overhead to obtain a data sample. Overview of MRI's research and analysis services, including air quality and emission measurements. Use of MRI instrumented aircraft for ambient condition measurements and emission concentration monitoring. 11:00: A data gathering device is emplaced atop a factory smokestack. Here, the company's source monitoring capabilities are demonstrated, including stack emissions and their environmental impact. Procedures for measuring particulate loading and particle size distribution. 14:15: Sampling and analysis processes for particulate control equipment design. Use of MRI's quantum image analyzer for data verification and reporting. 16:48: a probe is used to sample conditions inside a smokestack. At 17:04, an electrobalance is used, followed by a microscope. 18:54: another break in the film. 19:30: A large MRI monitoring station is erected at a new construction site in a rural area. Climatological data is important for construction planning. 21:00: Features and setup of the mechanical MRI weather station, including wind, temperature, humidity, and rain measurements. Field maintenance and data recording procedures for the mechanical weather station. 25:00: Ray-o-Vac batteries installed in a weather station. Permanent installations and additional instrumentation options for unusual parameters like lightning stroke counting. Incremental chart drive weather station setup and operation. 29:00: Conclusion highlighting MRI's range of meteorological instrumentation and services. Motion picture films don't last forever; many have already been lost or destroyed. For almost two decades, we've worked to collect, scan and preserve the world as it was captured on 35mm, 16mm and 8mm movies -- including home movies, industrial films, and other non-fiction. If you have endangered films you'd like to have scanned, or wish to donate celluloid to Periscope Film so that we can share them with the world, we'd love to hear from you.
