A machine is in production which can reduce large volumes of garbage into small hard blocks, on a continuous basis. The Refuse Compactor produces blocks which are rat resistant, and suitable for landfill, the company says. The self-contained, fully automatic unit consists of a screw feed, shredder
with rotary hammers, and a two-stage hydraulic compactor. Since no special plumbing or waste facilities are required, the unit can be installed in basement o r any refuse removal point. The company claims that all types of general refuse can be processed at the rate of 400-600 pounds an hour. Electronic Assistance Corp. 61

When jet aircraft fuel is treated with a new supplement, AnPol-J, exhaust smoke, odor, and other air pollutants
are reduced drastically, according to the manufacturer. The completely organic additive burns ash-free, and tests indicate it may provide a substantial decrease in turbine wheel and burner can deposits. as well as more efficient starting and running operations. AnPol Chemical Corp. 63 Gas sampler
A device for the determination of ambient air concentrations of fluoride gas is available. The battery operated, nonaqueous system draws in air (at a rate of ?hc.f.m.) through a particle collecting labyrinth which removes fluoride dust, then passes it through a small chamber packed with paper saddles to absorb the fluoride gas.

Floating debris and oil spills can be contained within an encircled area o r kept out of a protected area by means of the Spillgard, according to the company. The unit-consisting of 10 ten foot lengths of compressed asbestos rubber sheet, with foamed flotation material cemented along both sides so that the sheet rides upright-is available in 15” or 36” depth. The company says that the flame resistant device also has resistance to petroleum, oil solvent, and both salt and fresh water, is strong. flexible. easy to store, and can remain upright under a variety of sea and weather conditions.

The Model 150 fluid analyzer, utilizing the back scatter principle-a prefocused beam enters the process stream and bounces back to a readout chamber-is designed to measure heavy concentrations of suspended solids in industrial and processing applications. The company says the device is capable of mcasuring fluids and slurries up to 15% solids, and incorporates a system for continuously monitoring, measuring, and controlling suspended solids in the process stream. The Model 150 features solid-state electronics, no moving parts, easy installation, and requires no trained personnel. Available in two standard ranges-10-5000 p.p.m. and 5000-100,000 p.p.m.-the unit has application in mining, food processing, and paper industries, as well as in waste treatment. Gem Rad, Inc. 67

AIR POLLUTION CONTROL WITH MULTI-SEAL DYNACLONE
On-site incineration
A line of pre-sized Tumble-Burners for on-site incineration of solid industrial wastes is designed for smokeless, pollution-free operation. The company says this is accomplished by tumbling action combined with high temperature. oxygen rich atmosphere to guarantee complete combustion of all burnables. The units can be batch o r continuously fed, and can handle from 95-2 tons per hour of waste. Featuring a refactory-lined cylindx which rotates at 1 r.p.m., wet scrubber. exhaust fan. and prewired automatic contro!s, the pre-packaged units are easy to install and maintain.

Waste disposal system
The Loewy-Kompex compactor for waste disposal in large dwellings is installed at a New York City housing project. The unit is a carousel of treated paper bags that turns automatically (by air compression) to the next empty bag as each bag is filled to preset capacity. The company says the bags are odor-proof, vermin-proof. and wet-proof, and can be sealed for carting away. Scientific Pollution Control Corp. 69
Chrome ore is an important ingredient in high quality refractory fircbrick. Converting the raw product into usable form involves grinding/ crushing/screening operations calling for efficient, trouble-free dust control. That’s why General Refractories Company vents their process with a 12,000 C F M Multi-Seal Dynaclone. It operates with low presw r e drop, delivers dependable high volume collection. After better than 1 ?hyears of service, the Multi-Seal automatic bag cleaning device shows little wear. “We like the trouble-free simplicity of Dynaclone’s new bag cleaner. We particularly like the longer bag life we’re getting and the absence of bothersome maintenance problems,” says the plant’s maintenance superintendent. For trouble-free dust collection in your process, look into Multi-Seal Dynaclone. Multi-Seal is a simplified automatic bag cleaning device that makes self-cleaning Dynaclone more dependable than ever. It operates better, seals better, cleans better. Details arc in our Catalog 204.
