Recent advances in integrated circuit technology made it possible to develop the lowcost, battery-operated, recording, soil-frost measurement system described in this paper. This system utilizes the abrupt conductivity changes within gypsum soil-moisture blocks to indicate if soil is frozen or thawe

Motors are achieving substantial time saving (for instance 4rain to perform a task that takes 3-4 months using manual methods) on some engineering design tasks at their commercial vehicles centre with the recent installation of a CalComp 960 high-speed draughting system. The 960 combines the advant
Recent changes in the instrumentation associated with the High-Speed Friction Testing Machine show promise of revealing rapidly fluctuating friction phenomena with a resolution heretofore impossible. This machine, designed and built by the Laboratories staff some years ago under the sponsorship of t
