A compact, wholly self-contained liquid scin-

tilatondetector that can be used as a

whole body counter for small animals, as a

radioactivity counter for bulk samples of

foods, soils and other materials, and as an

arm-only counter on humans.

This versati'le and economical new instru-

ment enables the research worker to count

even natural levels of radioactivity con-

veniently. Because of the great sensitivity

and excellent counting geometry of the

ARMAC Detector, high counting rates

can be obtained with the administration

of very small amounts of radio-nuclides

.9 only 1/100 to 1/1000 of maximumn

permissible levels.

A complete system consists of the ARMAC

Detector and a Model 410A Auto-Gamma

Spectrometer, both mounted on a mobile

housing. Provision i's made for addition of

automatic data read-out or ratemeter pres-

entation. Complete information can be

ies of national character as their con-

tribution to the war effort. Their reportsdealt mainly with the United States,Japan, and Russia, but some of thelesser nations were included as well.Drawing on a tradition of culture andpersonality studies done in primitivesocieties, they sparked a massive up-

surge of interest in the study of na-

tional differences stated in psychologi-cal terms.

In this first of a series of surveys ofresearch in the social sciences to beconducted with UNESCO support, twoDutch social scientists, Duijker andFrijda, assess what has been and whatneeds to be done in the study of na-

tional character. They review the con-

fusing array of currently used ap-

proaches and conclude that the mostdistinctive and sound attack requiresthat we treat national character literallyas the pattern of personality characteris-tics present in a given population. Onlythus can we avoid confusing it with thepeople's history, their politics, or theirinstitutions. This, of course, requiresthe use of psychological "tests" or

measures which are valid cross-cultural-ly, and our guides to the literature makeit clear that there are not many whichcan qualify. It will be no great surprise,therefore, that Duijker and Frijda re-

port that social'psychologists have notyet, for even one country let alone forany set of nations, systematically de-scribed the distribution of personalitycharacteristics in the population and as-

sessed wherein the pattern is common

or distinctive. The methods for suchstudy are now more or less in hand,however, and we are convinced thatwith fuller resources the important fac-tual questions facing the field can beanswered. We cannot be equally confi-dent that we will explain what producesdifferences in the psychological compo-

sition of populations-assuming suchdifferences exist-or what consequences

they have in social action.There is a valuable bibliography of

almost 1000 items. The bibliography,and several chapters which focus ratherintently on a detailed review of the lit-erature, make this essentially a special-ist's book. Nevertheless, the presenta-tion is very well organized, and thestyle commendably simple and lucid.The book will be read with interest byanyone willing to open his mind to theprospect of a scientific study of nationaldifferences.

Digital recording system for unat-tended data acquisition over longperiods acquires synchronous data by a

tape-stepping method. At a steppingspeed of 30 steps per second, 38 hoursof continuous recording are handledwith one reel of tape. Data are recordedwith track widths and spacings said tobe compatible with most standard com-

puters or data transcribing systems.Tape widths of 1/2 3/4, or 1 in. are

available. (Minneapolis-Honeywell Reg-ulator Co., Dept. Sci367, 10721 HannaSt., Beltsville, Md.)

Preset timer is designed for use withany transistorized scaler. Two timebases, interchangeable by insertion ofplug-in cards, are provided: a 10-kcy/sec crystal-controlled oscillator anda 60-cy/sec line. A five-digit neon read-out expresses elapsed time in tenths of a

second for the 60-cy/ sec base and inone-hundred-thousandths of a minutefor the 10-kcy/sec base. Digits may bepreset in any decade, one decade at a

time. A printout feature is optionallyavailable. (Eldorado Electronics, Dept.Sci366, 2821 10 St., Berkeley 10, Calif.)

Sweep generator has a center fre-quency range of 5 to 1200 Mcy/secand a sweep width also 5 to 1200Mcy/sec. The generator uses a voltage-tuned magnetron operating from 2400to 3600 Mcy/sec and a fixed-frequencycavity oscillator at 2400 Mcy/sec. Theiroutputs are mixed, and the differencesignal is the generator output. The twofundamentals and other high-frequencycomponents are removed by a low-passfilter. An automatic gain control circuitcontinuously samples the swept outputto assure uniform signal level. Flatnessis said to be within ±2 db over a 100Mcy/sec width and within +0.75 dbover-all. Output is greater than 0.25volt (r.m.s.). (Telonic Industries Inc.,Dept. Sci379, Beech Grove, Ind.)

Variable phase standard generatestwo signals of equal amplitude differingin phase by any angle from 0 to 360deg as determined by front-panel con-

trols. The reference signal has a fixedamplitude of 50 volts (r.m.s). Thevector output, which may be displaced

1080

in phase, has a maximum amplitude of50 volts (r.m.s.) and may be attenuatedin steps of 50 mv. A front-panel selec-tor switch permits operation of any ofthree frequencies within the range 150to 3000 cy/sec. Each frequency can bevaried over a 4-5-percent range. Angu-lar accuracy is said to be +0.05 deg atany angle, and resolution is said to be1 min. The instrument is self-contained,requiring no external equipment foroperation or calibration. (Gertsch Prod-ucts, Inc., Dept. Sci380, 3211 S. LaCienega Blvd., Los Angeles 16, Calif.)

Pump is designed to produce uni-form flow over the range 30 to 500ml/ min. It is continuously adjustableover the entire range. Flow does notdepart from average setting by more

than 0.3 ml. The apparatus pumpsagainst a back pressure of 300 mm-Hg.Flow rate is said to vary less than 2percent with a pressure change fromzero to 180 mm-Hg. A variable-speeddrive unit, separately housed, may bedistant from the pump. Hold-up volumeof the pump is less than 40 ml. (SageInstruments Inc., Dept. Sci383, 9 BankSt., White Plains, N.Y.)

Reference voltage source simulatesthe d-c electrical output of transducerswith a setting accuracy said to be±0.05 percent. The device consists of apotentiometer of infinite resolution anda bridge network supplied with 115volt, 60 or 400 cy/ sec current andZener reference. Scale of the instru-ment, 12 ft long, can be graduated inseveral ranges in terms of the cardinalpoints of the instruments to be cali-brated, or it can be graduated in a

single range with up to 000 scaledivisions. The device is designed to testindicating instruments in the millivolt ormicrovolt range. (Howell Instruments,Inc., Dept Sci38 1, 3479 W. VickeryBlvd., Fort Worth 7, Tex.)

Null voltmeter has 13 zero-centeredranges from 1 mv to 1000 v end scale.Input impedance is 10 megohms in themost sensitive range and 200 megohmson the 300-MV and higher ranges. Ac-curacy is said to be within +2 percentof end scale. The instrument providesan output proportional to meter deflec-tion and can be used as a stable d-camplifier.

The New Brunswick Automatic pH Con-troller provides continuous regulation, mon-itoring and recording of pH in any activefermentation or chemical process at labora-tory, pilot plant or production levels.

This compact unit controls pH at any

pre-selected level throughout the entireacid-base range with an accuracy of + 0.1pH. Specially constructed electrodes with

insulated wire leads withstand repeatedsteam sterilization at temperatures up to250°F and pressures to 100 psi.The mobile apparatus, with electrodes, is

readily integrated in New Brunswick Fer-mentors as well as most other fermentationvessels. Find out how this apparatus cansolve your individual pH control problems.Unconditional One Year Warranty.
