Automatic Deeludging Valve s A PART of its hot-process lime-soda L water softener in which sludge must periodically be removed from a settling tank, The Permutit Co., New York, Ν. Υ., has placed upon the market an automatically operating valve for permit ting the flow of sludge from a container by gravity or under pressure.

Automatic operation of such a valve is highly desirable because periodic desludging by hand is apt to be overlooked or postponed for such an interval as to impair the efficiency of operation. With automatic desludging this is accomplished under precise control, assuring uniform conditions. The valve is motor-operated and of simple construction.
Fire Pump AUXILIARY fire protection for factories, JA. warehouses, docks, and industrial plants is afforded by a new special-duty fire pump installed as part of the "Clarktor-o" industrial tractor, made by Clark Tructractor, Battle Creek, Mich. The centrifugal type pump, meeting all test requirements of the National Board of Fire Underwriters, can handle any kind of water, regardless of dirt. In practice, the very high-pressure email nozzle supplied creates a fine mist at the end of the stream of water, thus quenching the blaze. A floating, flexible drive between motor and pump is provided by a patented power take-off. Automatic primer primes the pump and keeps it primed by means of a vacuum from the motor intake manifold. When taking supply through a 4-inch suction opening from a 30-pound hydrant, the pump will deliver 400 gallons per minute at 120 pounds pressure, with the motor running 1800 r. p. m.t which is its normal controlled speed when operating the tractor. Pump ca. pacity and speed may be increased by adjusting motor governor. The tractor power plant consists of a 46-horsepower, 6-cyUnder engine, equipped with air cleaner and renewable cartridge-type oil filter. The pump is installed on the front end of any "Clarktor-6" Tructractor behind the bumper plate, and is easily accessible for servicing. (Conl-inued on page 600)

The Hydro-Clone, as illustrated, separates the dust from the air by a combination of centrifugal force and wet impingement and washing. The dust Η precipitated in the form of sludge in t h e dewatering tank which is a part of t h e system and the water is recirculated through the Hydro-Clone, thus wasting no water.

Using a standard glass measuring-cell assembly, in which corrosion and catalytic action are definitely avoided, it holds its calibration continuously. * Sulfuric acid mist is removed by an efficient filter. The cell assembly operates for weeks without attention. Changes in humidity no longer affect calibration, and lag is minimized, as it is possible to draw the continuous gas sample from the flue immediately after it leaves the burning chamber.

Should it be desirable to collect usable dust in a dry form, this dust is separated in a Sturtevant Dry-Clone which connects with the Hydro-Clone where the fine nui sance dust is suppressed as a sludge. Thus, two products are obtained, a large per centage of coarse usable material and a sludge containing all the nuisance dust. Should it bo desirable to convert all of the dust to sludge, then the Dry-Clone is not used. In handling fumes, smoke, fly ash, and dust at high temperatures, a combination of the Dry-Clone and HydroClone is used. In this case the Dry-Clone serves as a pre-cooler and a trap for the heavy dust and the air passes to
Γ Ή Ε commercial availability of normal
A caproic acid at a new low price is an nounced by the Carbide and Carbon Chemicals Corp., 30 East 42nd St., New York, Ν. Υ. Now selling at 35 cents a pound in drum quantities, caproic acid becomes a valuable source of the hexyl group for many industrial syntheses. Caproic acid is the normal, straightchain, six-carbon atom compound of the fatty acid series. It is a colorless liquid of character 1st ic odor. It boils at 202° C , freezes at 4.7° C , and has a specific gravity of 0.9280 at 20/20° C. It is only slightly soluble in water, but is soluble in alcohol and many other organic com pounds. The commercial material con tains well over 98 per cent caproic acid by weight. 'New esters, anhydrides, salts, ketones, amides, and other derivatives useful to industry can be prepared from caproic acid. Its esters are important in the manufacture of flavors, perfumes, and es sential oils. The ethyl, amyl, and allyl esters, in particular, are used as synthetic flavors. Caproic acid also offers possi bilities for the production of cellulose esters which have greater solubility in organic solvents than those of lowerboiling acids. Other derivatives, such as the anhy dride, salts, or amides, have higher boiling points, greater oil solubility, and lower water solubility than those obtained from acetic, propionic, or butyric acids. Fur thermore, the normal hexyl group can be introduced into certain pharmaceuticals, resins, rubber chemicals, and related prod ucts by means of caproic acid.
