The dialogue between the semaphores of the two roads allows the alternation of the green signal as a function of the traffic intensity, while the pedestrian crossing is on request. The automatic control of the semaphore system is performed through PLC not with the normal cyclic timing: only the presence of at least one car determines the green signal of the relevant semaphore, allowing the transit of all the cars between the two detecting sensors. Smart Traffic Lights Simulator system represents a crossing between two one way streets, each controlled by a semaphore and provided with three pedestrian crossings with semaphores, too. The present cars are displayed through LED, whose control is assigned to an electronic circuit separated from the PLC.

The stainless steel experimental arrangement forms a smooth, impermeable beach. The inclination of the beach body can be continuously adjusted. The experimental layout consists of a beach body, a mounting plate and an inclination adjustment bar with a locking bolt. The accessory is intended to enable the user to investigate the behaviour of waves on a rising beach; the unit is used in combination with the Wave Generator. In this way different steeply rising beaches are very easy to simulate.

An electrical heating element is fitted into the block, the electrical supply provided from a variable transformer with front panel control so that the rate of heating and final temperature can be controlled as desired. Temperature Measuring Bench is designed to demonstrate a number of commonly used methods of temperature measurement, and provides the means for calibration and accuracy comparisons of the different methods. Hence, suitable measuring devices can be found for particular applications. The main unit comprises a bench mounting console which contains the hot water bath, furnace, ice bath, a digital resistance thermometer/thermocouple instrument, digital NiCr/NiA1 thermocouple instrument and power supplies. The hot water bath comprises a Dewer flask whose lid is fitted with a combined heater stirrer unit, low water cut out to provide boiling water reference at 760 mm Hg barometric pressure. Features are provided so that a number of faults commonly occurring in thermocouple systems can be demonstrated. In addition the unit may be used to provide a temperature measuring facility for use with other experiments. The furnace comprises a brass block with holes drilled to accept a glass thermometer, resistance thermometer and thermo-couple. An over temperature thermostat is set to limit the maximum temperature to 250ºC. The heater unit incorporates an adjustable thermostatic temperature control and over-temperature cut-out.
