of the cycle in full seconds rather than frictionai seconds. The equipment includes provision for optional preset counting interval or preset count accumulition. There are sensing devices to record the kind of measurement made (whether foil activation or background count), plus manual switches which may also specify how individual measurements will be processed later by the computer, on a card-by-card ind scaler-by-scaler basis. Data are processed by an IBM-704 computer programmed to produce plotted traverses as weil as tabular data. From 25 to 100 foilactivation measurements per minute may be processed, depending on the number of entries per card and the use of preprocessing equipment. The data reduction includes many repetitive steps which the computer does very precisely and economically. (auth)
