Abstract: The pack is folded from a card having a generally rectangular panel forming the front of the pack joined to a generally rectangular panel forming the back of the pack via a spine. The edges of the panel, remote from the spine are adhered together, if necessary with the assistance of a flap, to lock the staggered stack of razors within a slot in the edge of the panel, the back panel of the pack having one or more cut-outs or flaps with which portions of the razor handles engage thereby holding the handles in position.

Abstract: A radiation analysis instrument is described for measuring the characteristics of radiation emanating from a source (XS). The instrument includes two absorbers (a, b) and corresponding detectors (10, 12) with the detectors being disposed in the path of the radiation and the absorbers being interposed between the corresponding detector and the source. A circuit (16) digitizes the analog signals derived by the two detectors and provides the digital values to a microcomputer (18) which stores these digitals values within a memory (50). A microprocessor (48) processes the digital signals stored within the memory (50) to analyze characteristics of the radiation emitted from and the potential applied across the source (XS). This instrument is particularly useful in measuring the kVp applied to X-ray tubes.
