Transmission Brakes, is cut off, for positioning, quick stopping in emergency (safety brakes), automatic speed control, providing a tension (. for reeling) or simply for bringing the equipment to rest in a reasonable time. Just as the motor is used to accelerate the drive, so the brake is needed to decelerate, hold, or, in a few special cases, control it.

Shafts and Couplings,The need for a flexible coupling as a means of joining a prime mover and driven machine is now universally accepted. Its purpose is to provide a flexible element between two machines, absorbing or minimising torsional fluctuations and relieving bearings of loads imposed by inaccurate alignment or subsequent movement.

Pneumatic Drives,To choose a single word to describe the whole range of pneumatic power units is extremely difficult. The only term which seems to cover all the various mechanisms is ‘actuator’ and, therefore, this chapter is devoted to an examination of linear, semi-rotary, and rotary actuators.
