Punched-Card to Magnetic-Tape Converter

THE principal devices for converting source data to magnetic tape recording for Univac* are the card-to-tape converter and the Unityper. * Unityper is the, logical conversation medium for input of 'otherwise untreated data. Files of punched cards, however, represent to the owner an investment of time and expense in preparing material for other treatment. The card-to-tape converter provides a me...

A punched-card system for the laboratory.

A punched-card system was developed to simplify the administrative aspects of the clinical chemistry laboratory. In it a three-part requisition and samples are matched and given a laboratory number. The third copy of the original laboratory requsition is a charge card also used as a name file for the day. Prepunched cards, coded for laboratory tests, are used for each test requested. The labora...

Near-Infrared Spectra of Ultraluminous Infrared Galaxies.

Near-infrared spectra with a resolution of lambda&solm0;Deltalambda approximately 1100 in the rest-wavelength range of 1.8-2.2 µm have been obtained for a complete sample of 33 ultraluminous infrared galaxies (ULIRGs). Of the 33 objects observed, two show evidence of a central active galactic nucleus (AGN) through either a broad Paschen-alpha line or emission in the 1.963 µm fine structure of [...
