HIGH-TORQUE MECHANICAL FLOWMETERS.
The 16-page bulletin describing this line of flowmeters carries an interesting pres entation of the basic facts about the in struments. The manufacturers point out that frict ion is negligible and rugged construction can be used. The way in which this operating principle has been carried out is described in detail. There are large-sized photographs of t he essential working parts of the meters, as well as a description of the special features. The bulletin also points out that these flowmeters may be supplied to make one or two additional simultaneous records of temperature and pressure on the same chart in addition to the flow record. This bulletin is well worth reading where there are problems of measuring flow. No. A2-4LIGHTNIN
MIXERS.
In this new cata
log the manufacturers of Lightnin mix ers have spared no pains to give the im portant details about the various models which are offered. Included for the first time are a one-thirtieth horse power laboratory model, portable ex plosion-resistant mixers, portable paintmixing units, and a new gear-drive unit for fixed*application on large tanks. Pho tographs and drawings have been used effectively in indicating the possible applications of the different types of mixers to process work. No. À2-1. MOTORS.

TYPE CS MOTOR BLOWER.
A recently
issued bulletin describes this type of unit designed for service requiring air at 1-pound pressure, and in volumes from 325 to 3200 cubic feet per minute. The manufacturers point out that this type of motor blower is particularly suited to industries where oil- or gas-fired furnaces are used. This 4-page bulletin carries photographs, performance graphs, and a useful size and dimension table. No. A 2-7.

F ALL his ingenious tools perhaps none is so indispensable to the student of chemistry as the concept of the gram molecular volume. With its aid he can measure molecular and atomic weights, and calculate the volume of any given weight of a gas. To aid the student of chemistry in visualizing the gram molecular volume and to make it impressive, most chemistry lecture tables display a cube 11 inches high. But only too infrequently does this silent sentinel serve the purpose desired. It is not unusual for 30 per cent of a class to come to grief when a question requires the use of the gram molecular volume.
INDUSTRIAL RAYON CORP. has filed a
registration statement with the S E C covering 247,625 shares of capital stock, rights to subscribe to the stock, and installment subscription receipts. This is part of a plan to offer present stockholders an issue of 151,625 shares of capital stock, no par, on the basis of 1 additional share for each 4 shares held, to defray part of the costs of an expansion program which involves expenditures in the neighborhood of $14,000,000. The company is considering construction of additional facilities at Cleveland to provide for an annual productive capacity of about 10,000,000 pounds of staple fiber from viscose b y the mechanized continuous process. It also intends to erect a new plant in Lake County, Ohio, for the manufacture of rayon yarn from viscose. For the 10 months ended October 31, 1936, the corporation reported a consolidated net profit of $1,051,978 after all charges, but before provision for federal surtax on undistributed income.
