A small amount of hydrochloric acid is a d d e d during recrystallization to prevent t h e precipitation of any iron that may b e present as an impurity. The solution used to wash t h e precipitate consists of 75 volumes of water, 4 0 volumes of concentrated sulfuric acid, a n d five volumes of concentrated hydrochloric acid. After several washings with this mixed acid, three washings with acetone are recommended. Alcohol, however, cannot be used for this final washing because in some w a y it causes interference i n subsequent recrystallizations, probably through complex formation.

Sulfur Bichloride Vapor Aids Paint, Ink Drying Development of an unusual method for drying coatings of ink, paint, or varnish with sulfur dichloride vapors was reported recently. Said to be adaptable to such operations as oilcloth and linoleum manufacture, furniture and appliance finishing, and many types of printing, the process consists of passing the coated material through a chamber where sulfur dichloride vapors react with the coating and harden it within a few seconds. The mechanism of the reaction is not definitely known. It is thought to involve an addition reaction with drying and semidrying oils, and a substitution reaction if the oils are of the nondrying type. In addition, copolymerization effects have been suggested, and the process has been likened to the vulcanization of rubber. The reaction is said to produce a hard film or deposit in 10 seconds or less in the case of unsaturated oils, and in 30 seconds with saturated ones. A cleaning step follows contact with the vapor since sulfur dichloride. can have a deleterious effect on the material being coated or printed.
Ethyl Alcohol Helps Speed New Corn Syrup Analysis A new procedure for separating dextrose, maltose, and dextrin fractions from corn syrup, developed recently at a government laboratory, is said to yield more accurate results and to cut time required for the analysis to IV2 hours. Apparatus required consists of a simple glass column filled with equal weights of carbon adsorbent and a diatomaceous earth filler. The top of the tube is coupled to a nitrogen source so that 30 to 50 pounds pressure can be applied to increase the liquid flow rate. Sample to be analyzed is passed through the column, after which water is run through to remove the adsorbed dextrose, leaving the other two fractions intact. Next, a 5 per cent ethyl alcohol solution removes the maltose fraction, and finally dextrin is removed with a 15 per cent ethyl alcohol solution. At the end of the run, a wash with 95 per cent ethyl alcohol and then with water removes all traces of carbohydrates.
Develop New Type Bandage A new type of cotton bandage developed by the U. S. Department of Agriculture is now being made commercially for the Armed Forces and may soon be available for civilian use, according to a recent announcement. The outstanding feature of the new bandage is its ready adaptability to irregular contours of the body. This property is achieved by allowing ordinary open-weave gauze to shrink freely in a 20 to 30 per cent caustic solution, followed by washing and drying under a minimum of tension. In shrinking, the yarns develop a high degree of crimp and elasticity, making the bandage essentially self-fitting and self-tightening, it is claimed. The modified gauze is non-slipping and said to be especially suitable for bandaging joints where a close fitting but flexible dressing is required.

Experiments carried out at a leading university have shown that laying birds? consuming a marginal level of protein in t h e ration were helped by adding vitamin B12 to> the feed. It was found that the vitamin B12 aided the birds in making more efficient use of available protein, thereby increasing e g g production. The incidence of feather picking with birds fed vitamin B12 and soybean meal was less than with birds fed fish meal. From these experiments, it is evident that vitamin B12 plays an important rote in protein utilization.
Synthetic 'Guinea Pigs' Produced with Cortisone Help Medical Research Synthetic "guinea pigs" are the latest marvels to be produced with the help of cortisone, according to recent reports. These asre laboratory animals which, after receiving cortisone treatments, become subject to liumao diseases they would not ordinarily get. Ralhbits, for example, have been made to contract typhoid fever after being given large doses of cortisone. Mice have been made susceptible to a number of other human diseases by combination treatments with cortisone and IX-rays, it is claimed.
New Pain Killing Drmg Effective for 10 Days A drug which is claimed to relieve pain for ten days following surgery was reve=aled at a recent medical society meeting:. Des-cribed as a local anesthetic which numbs tlte nerves, the drug is injected at the site of tlie operation or into the nerve trunks leadiog to the site. By the time the drug wears off, tlie wound often no longer hurts, say t h e doctors who demonstrated its use. In chest and a_bdominal operations, the freedom from pain gained by using the drug allows patients to move about much earlier than is usually possible- which is claimed to be good medicine i n itself.
forms to U.S.I.'s narrow specification limits. In addition to its versatile properties, convenient packaging has further increased the value of Solox to all users. It is readily available from paint, hardware, and many department stores throughout the country in easyto-handle and easy-to-pour pint, quart, and gallon containers. For larger users, the solvent is available in conventional 5 and 54 gallon drums, as well as in tank wagons and tank cars. Denatured ethyl alcohol, from which Solox is formu- HAIe]; lated, is the only thinner suit-
Ozone-Resistant Rubber May Yield Colorful Tires Tires that match the color of the paint on your car may soon be possible with a new synthetic rubber now being produced in pilot plant quantities. The new material, known as chlorosulfonated polyethylene, is described as chemically different from existing types of rubber. It is reported to have remarkable resistance to wear, heat, and weather, and to be completely resistant to the corrosive effects of ozone, the constituent of the atmosphere responsible for the deterioration of natural and many synthetic rubbers. Good physical properties can be attained without the addition of carbon black, it is claimed, and colored fillers, substituted for black, are expected to make possible the manufacture of rubber products, including tires, in various colors.

Solox Solvent
able for use with shellac. The mild odor and superior solvent action of Solox make it ideal for all shellac purposes — for thinning, for softening and removing old shellac, for cleaning and brightening shellacked surfaces, and for cleaning shellac brushes. Furniture refinishers have also found Solox an excellent diluent for non-grain raising stains to obtain the desired deptJh of color shade. Marine, Camp Stove F u e l Solox is popular with boat owners and campers as an easily handled and efficient fuel for alcohol-burning stoves. Solox is also widely used to kindle fires in outdoor charcoal grills, and it is a superior fuel for chafing dishes. Solox is an effective general-purpose cleaner. Mixed with either plain or soapy water, it is excellent for cleaning grease and grime from painted walls and woodwork. Used straight, it is a n efficient cleaning agent for a diversity of products including linoleum, motors and machinery parts, typewriters, and jewelry. Miscellaneous applications for Solox include its use as a solvent for rosin to be painted on young fruit trees as a repellent, as an aid in ironing clothes, and in photography to dry prints and negatives. Industrial Uses Industrial use of Solox is large and continually expanding. Demand for the solvent comes from a wide variety of industries where alcohol is required but -where the use of a specially denatured alcohol formula is not essential. U.S.I.'s local sales offices in all principal cities will welcome the opportunity to answer inquiries regarding Solox.

New Electronic Method Measures Oil in Soybeans In 1 5 Minutes or Less A new method is reported to reduce time required for determining oil content of soybeans to 15 minutes or less as contrasted with the several hours required by the official method now in use. The method centers around use of a high-frequency oscillator to measure the oil in solution of standard solvent. Soybean samples are first ground in a special grinder-extractor with the solvent. After filtering, the solvent-oil mixture is placed in t h e cell of an electronic oscillator which measures the dielectric constant. T h e reading is then converted to p e r cent oil by means of a table obtained from analysis of a large number of soybean samples by the customary method. Results o n a single sample can be obtained in 15 minutes, but in quantity, 20 to 30 determinations per hour could be made by two analysts, it is said. Estimated cost of t h e equipment, if used at capacity, is claimed to be about one-half that of the equipment needed for testing the same number of samples by the present method.
New Photo-Copying
Method
An experimental photographic system for making quick, inexpensive copies of documents in less than a minute was demonstrated recently. All equipment for the operation is contained in a unit slightly larger than a standard typewriter, and average room lighting conditions are used. T h e process involves use of paper coated with a special emulsion which, although light sensitive, is too slow to be affected by ordinary lighting. When the paper is exposed with a document to a bright light and then placed in a special activating solution, a master image composed of soft photogelatin and dye is quickly formed. When this image is placed in contact with a sheet of plain white paper, a thin layer of the dyed gelatin is transferred to the paper, forming a positive of the original. Since the reproductions do not come in contact with t h e activating solution, they come out virtually dry and can be used immediately, it is said.

A project under way at the University of California College of Agriculture is attempting to determine how much of a micronutrient a plant needs to grow. Under an Atomic Energy Commission grant the division of plant nutrition will study the uptake of certain minerals through the use of radioactive tracers. Iron, manganese, zinc, and copper are the principal micronutrients in question. Others that may be studied are chromium, cobalt, nickel, molybdenum, and vanadium. These minerals are usually present in fertile soils, b u t t h e exact amounts necessary for different plants and trees to grow has not been fully worked out. Culture solutions, synthetic soils, and purified clays of known mineral composition will be tagged with radioactive micronutrients for growing the test plants.
