Any input that can be represented by a direct current voltage as low as 10-mv. full scale can be monitored by the Hagan AIM (alarm indicating monitor). U p to 200 points may be checked every 5 seconds on a large variety of plant operations—and alarms of several kinds can notify responsible personnel. Display lights on the AIM's control panel indicate to operators that out-of-limit conditions are occurring and indicate die name and number of the control point. A warning horn will sound when specification limits are exceeded, as well as an alarm light on the central panel. T h e horn may be silenced by an acknowledgment button, but the light will remain on until limits are not exceeded. Limits are individually set by inserting pegs in a pinboard. Alarm accuracy is ± 0 . 1 % of full scale. Detection of an out-oflimits signal is obtained by comparing the voltage from the alarm set point pinboard to AIM's direct current amplifier. If the amplifier voltage is higher or lower than the set-point reference voltage, an alarm comparator, which has a resolution to one point in 10,000 full scale, produces an alarm pulse. This pulse closes the memory relay, energizing the alarm light and the audible warning horn. All alarm functions are combined Circle No. 64 on Readers' Service Card
A I M will monitor up to 2 0 0 points every five seconds in a variety of operations
in one compact instrument. The read-out and alarm panel for one 200-point AIM will fit into a panel area of 19 X 47 inches. Precise readings over wide thermocouple ranges are accomplished by the use of range suppression and linearization. For example, temperature readings in the range of 900 °F. would show up with the lower 800 degrees suppressed. T h e operator selects the point desired and adjusts the temperature range selection switch until the meter reads on scale. A suppression increment of 900° and a scale reading of 68° would, for example, be a temperature of 968° F. Some facts on AIM are • Alarm accuracy, ± 0 . 1 % full scale •Read-out accuracy, ± 0 . 1 % of indicating scale • Set point stability, ± 0 . 0 3 % full scale • Scanning rate, 5 points per second
• Alarm comparator resolution, 1 part in 10,000 • Voltage output, 10 volts • Power supply, 110 volt, 60 cycle • Power consumption, 200 watts Simple self-checking devices incorporated into the AIM provide excellent maintenance and variation checks. A three-position switch is provided to run a complete circuit check that will verify operation of the detecting amplifier, alarm circuit, and all indicating lights. Another switch will introduce a continuity check of all input circuits and input selection relays. Two hundred point AIM costs approximately $20,000. Dept.

(usually in dry powder form) to reduce viscosity to t h e desired consistency Only a little Marasperse is needed to reduce slurry viscosities, or to prevent micron-sized particles from settling out of suspensions. Usually less than 3%, based on the weight of the solids in the aqueous system, will do the job for you. For example, manufacturers of gypsum board require just 0.15% Marasperse in their stucco slurries to give them more fluidity at lower water contents . . . And producers of pesticide wettable powders include but 1.5% to 2.0% Marasperse in their powders to ensure satisfactory dispersion in spray tanks. What's more, the Marasperses cost only a few cents a pound! Tell us about your viscosity problem. If it's typical of one of the many that the Marasperse dispersants have licked, we'll give you specific information based on user experience. If it's something new or unique, we'll tell you h o w to test samples of the Marasperses to determine whether or not they'll be useful to you.
