At the 1962 ASME meeting in Houston, Allison submitted a paper describing the possibilities of industrializing the T56 aircraft engine. Since that time, Allison has modified the engine for gas burning and is operating one as a prime mover for a 2000-kw generator at the Indianapolis Plant. In addition, two additional units are to be installed in the gas-transmisson field driving centrifugal gas compressors. This paper gives a description of the units and a status report on the installation and operation. Photographs of the installation and performance data, as necessary to complete the report, are included.

Приведены результаты исследований экспериментального картофелекопателя с ротационной сепарирующей поверхностью. Особое внимание уделяется обоснованию конструктивных параметров и определению рабочих характеристик нового сепарирующего устройства. На основе анализа результатов экспериментальных исследований определены наиболее оптимальные режимы работы экспериментального картофелекопателя.Research results of an experimental potato digger with rotational separating web are published in this article. Special attention is paid to definition of design characteristics and performance data of the new separating device. Admissible operating modes are defined on the basis of the analysis of results of pilot studies of the experimental potato digger.

Earlier stress studies under laboratory conditions show that heart rates from 100 to 110 bpm are associated with significant decrements in missile-tracking performance. Data from real missile tracking by 8 operators with no stress deliberately induced indicate, however, that performance is unaffected up to 135 bpm, and only moderately affected in the 135- to 170-bpm region. The disagreement between the two sets of results highlights the difficulties in generalizing from stress experiments.
