Other Important Features are: Oval hand- ' wheel, ports-in-line. non-rotating bearing plate to protect diaphragm from rotating friction of stem, and use of multiple puncture and fracture-proof diaphragms designed to resist wear and corrosion. Available in a complete range of sizes with flare and solder connections. Welded steel con struction. Negligible pressure drop. Screen can be taken out for cleaning without removing strainer from line. Very large screen area. Light weight. Baffle prevents heavy particles injuring screen. ABSO-DRY PRESSURE SEALED DRYERS For Refrigeration and Air Conditioning The exclusive Henry vacuum process first removes every trace of moisture, then the dryer is charged with dehydrated air. Loosening a seal cap prior to installation produces hissing sound, a guarantee of original factory dryness and freedom from leaks. Other Features of Henry Dryers-- Perforated Dispersion tube is connected to inlet port ana exposes entire volume of dehydrant to penetra tion by refrigerant. Minimum pressure drop. No channelling. Compression Spring maintains uniform tension on dehydrant at all times and compensates for changes in volume. Soldered or Flanged Shells--models are available with either soldered cap or Banged end shells. Flange is distortion-proof. Shells not exceeding in. in length are drawn in dies, so that they have only one joint. TWO DEHYDRANTS--Choice of two de hydrants; Activated Alumina or Silica gel. Type 757 Cartridge Dehydrator1 Flanged shell dehydrator with replaceable cartridge. Type 743 Refutable Dehydrator Screen tube assembly soldered to outlet connection. With dispersion tube. Type 712 Dehydrator Soldered brass shell with dispersion tube. APPROVEti FOR ARMY AND NAVY .USE 1012 Controls and Instruments Illinois Testing Laboratories, Inc. 422 North LaSalle Street, Chicago, Illinois Alnor Manufacturers of ALNOR Thermometers, Pyrometers, Temperature Controllers, and Air Velocity Meters The Alnor Velometer is an instantaneous, direct-reading air velocity meter designed for convenient, rapid deter mination of air velocities in air conditioning,, heating antj ventilating, and exhaust systems. It gives instantaneous direct readings in feet per minute, without timing, calcu lations, or reference to tables or charts. Low range air velocity readings are taken by holding the Velometer in the air stream. High range readings are obtained by the use of tube connected special jets, available in 17 types providing for convenient use in any location. Accurate information on performance of equipment, duct systems, etc., can be obtained with a few moments inspection with the Velometer. It can be effectively used to locate drafts and leaks around windows and doors, or in duct systems. The Alnor Velometer is built in several standard ranges from 20 fpm to 6000 fpm, and up to-3 in. static or total pressure. Special ranges available as low as 10 fpm and up to 25,000 fpm velocity and 20 in. pressure. Alnor Electrical Resistance Thermometers, available in single and multi-point types, are ideally suited to air con ditioning, heating and refrigeration installations. Ther mobulbs may be located at any point up to 1000 ft from the instrument. Indicating thermometers can be furnished with capacities up to 14 points. Standard types include round, rectangular, horizontal edgewise, and portable thermometers. Instruments may be installed in office or engine room and thermobulbs located at any desired point in the building or on the roof. Accurate temperature measurements at the remote locations are obtained merely by moving the selector switch. Alnor Pyrometers include a wide range of portable and wall mounting types, both single and multi-point instru ments, for a variety of industrial temperature measurements. Temperature readings of molten metals, industrial furnaces, and similar equipment, and temperatures of surfaces, either metallic or non-metallic, moving or stationary, are readily obtained with standard Alnor Pyrometers. Bulletins describing Alnor instruments and accessory equipment will be sent upon request. 1013
