Gears transmit rotational movements. They adapt the torques and speeds of a consumer drive according to demand. Deals with a fixed gear unit. Worm gears are normally deployed to gear down, and are mostly self-locking. This enables components to be compared directly with the complete system. The gear unit comprises a worm gear with an upstream spur gear stage. Combining the two types of gear in a single box enables high transmission ratios to be attained at high levels of efficiency in a compact space. The comprehensive and clearly structured instructional material, which includes a set of drawings, sets out the individual assembly steps in detail and provides additional information on the areas of application, mode of operation and design of the assemblies. Large-format drawings suitable for workshop practice can be attached to the display board at the rear of the trolley. All steps can be demonstrated to, and then performed by, the students themselves.

The Essentials of Process Control (EPC) range of products takes students through the fundamentals and principles of process control and progresses to give them a thorough grounding in the control of physical processes. Four independent process units demonstrate level, flow, temperature and pressure as the controlled variable.
The effect of making changes to the system or to the controller configuration can be quickly investigated by applying repeatable disturbances or step changes to the process. The concepts of closed loop control, including on/off control, proportional control, proportional/integral and proportional/integral/derivative (PID) control can be explored and demonstrated. Some units also cover both time proportioning and analogue control of the same parameter. Comparison of the responses obtained with different control settings clearly demonstrates the need for correct matching of the controller to the system characteristics. Each process is supplied complete with software that allows it to be controlled using a Windows PC via a USB connection.
The plc has the control algorithms implemented in ladder logic and so are fully accessible to the user. To demonstrate industrial control systems, two further controlling devices are available, a full function commercial PID controller with autotune, and a programmable logic controller (PLC). This is demonstrated by a sensor calibration apparatus designed specifically to demonstrate this subject. Another fundamental aspect of process control is an understanding of sensors and how they are calibrated.

The practice kit provides the material necessary for students to systematically learn how components can be joined together in a professional way using pins. Both flat and cylindrical parts are pinned together. We recommend that the exercises are carried out in a workshop, as all preparations such as scribing, drilling, clamping, reaming and joining must be carried out in a correct and proper manner by the student. The material is clearly laid out on a plastic tray. The well-structured instructional material outlines all the necessary technical information and provides a step-by-step guide through the exercises.

Compressed air is often used instead of electrical energy, particularly in workplaces where there is a risk of explosion of combustible gases. The heat generated by compression is dissipated by cooling fins. Compressors are at the core of compressed air generator plants. These plants are used where compressed air is used as a source of energy. The compressor is driven by a V-belt. This enables references to be made between individual components and the Large-format drawings suitable for workshop practice can be attached to the display board at the rear of the trolley. A second fully functional compressor, permanently mounted to the workbench, can be used for demonstration purposes. A disassembled piston compressor is contained in the drawers of the trolley cabinet which also holds the tools and assembly aids, small parts and gaskets required for assembly.

The lower value (diastole) corresponds to the pressure that we have in the arteries between two heart beats. The upper value (systole) is the maximum pressure that is recorded in the artery in consequence of the heartbeat. In blood vessels there must be a certain pressure in order that the blood can properly flow. Each heartbeat causes a pressure wave that is transferred to the arteries. Therefore, it is necessary to properly evaluate the pressure and its variability through a pressure and heart beat digital meter.
