MHD Thermal Lags Spotted by Recorders VALLEY FORGE, PA. — Thermal lags in General Electric's Magnetohydrodynamic Continuous Flow 'facility are quickly spotted and adjusted through use of two dual-pen ElectroniK 17 re corders. These instruments monitor gas and surface temperatures within heater, nozzle and MHD generator during three-minute startup period. After startup, continuous records are made of generator em.ranee and exit gas temperatures and two cathode surface temperatures within the generator. When temperatures reach preset values, relay-controlled indicator lights tell op erators to disconnect the oxygen ana lyzer and begin seeding carrier gas. Research is aimed at making possible nuclear-powered MHD generators with high power densities required for space and defense applications. Calibrated accuracy of these Elec troniK 17's is ± 0 . 2 5 % . Solid-state circuitry and exclusive Honeywell infi nite-resolution Stranducer(™> rebal ancing element gives these instruments extremely long and accurate life, and allows them to operate over an ambient temperature range oi 0 to 130°F. Low initial cost, low current consumption, low upkeep and maintenance expense make the ElectroniK 17 the most eco nomical high-speed servo recorder available for today's demanding data acquisition requirements.

New Portable Lab Recorder Measures 100/zv to lOOv PHILADELPHIA, Pa. — The first portable lab recorder capable of measur ing voltages ranging from 100 micro volts full scale to 100 volts full scale without auxiliary equipment, has been announced by Honeywell. This new in strument, the ElectroniK 19 strip chart recorder, combines a wide measuring range with a variety of features that makes it one of the most versatile re corders available for laboratory or test applications. The unit is only 8%" high by 8%" wide by 11" deep, and weighs less than 20 pounds. It comes complete with integral carrying handle, power cord, and rubber feet. In introducing the new instrument, Charles Wilkins, Laboratory Equipment Market Manager, emphasized that the ElectroniK 19 recorder has been de ELECTRONIK 19 PORTABLE LAB RE CORDER has a range from 100 microvolts signed specifically to meet the needs of to 100 volts full-scale, weighs less than 20 the laboratory and test markets.

ElectroniK 16 Recorder Introduced P H I L A D E L P H I A — Honeywell's Philadelphia Division has introduced the ElectroniK 16 potentiometer, a new strip-chart recorder offering many standard features that are optional on other recorders. "The ElectroniK 16's modular design concept, along with a number of customer-oriented features that make it convenient to install, maintain and use, makes it the easiest to work with recorder on the market today," said Charles Mclntire, sales manager of the Philadelphia Division. "For example, the instrument mounts directly into a 19-inch relay rack without using adapters. It has a new, highperformance, transistor servo-measuring unit. Chart-changing time has been reduced to less than a minute. And we can supply an optional pre-loaded chart transport that permits charts to be changed in approximately 10 seconds." Mechanical layout of the recorder is such, Mclntire said, that most available

This permits the customer to later add features previously available only as factory-installed equipment or not possible at all if certain other options also were desired.
"All adjustments can be made simply by sliding the chassis forward," Mclntire noted. "The ink supply can be refilled so easily that the instrument's recording operation is not interrupted. The electrical span and zero controls are made entirely by precision potentiometers specifically designed by Honeywell for this function. And a new type of camoperated backset switch has been created, again with simplicity of adjustment and stability of operation in mind." The ElectroniK 16 is currently available in single-pen, two-pen and multipoint models. Among the options available are an Adjustable Range Unit, chart supply indicator, retransmitting slidewires and event markers. The multipoint recorder has an option whereby any combination of 1 to 24 inputs can be selected by positioning appropriate buttons, and another option giving plugboard selection of alarm points.
