- Final Engineering Report Covering Austin Beta-Gamma Hand and Foot Checker
- Abstract: "This final report discusses the project objectives and the manner in which these were attained in connection with the design and manufacture of the Austin Beta-Gamma Hand and Foot checker (Fig 1). Improvements incorporated to conform the equipment to modern production methods, as well as practical changes to achieve automatic operation and increased stability and to facilitate and simplify maintenance procedures, are covered in detail. The report also includes photographs (Figs. 2 and 3) and a schematic diagram of the final product (Fig. 4)" (p. 1)
