Stop controls

Motor-driven compressors usually operate at constant speed, and other methods of controlhng the capacity are necessary. On reciprocating compressors discharging into receivers, up to about 75 kW (100 np), two types of control are usually available. These are auto-matic-start-and-stop control and constant-speed control. 

Automatic-start-and-stop control, as its name imphes, stops or starts the compressor by means of a pressure-actuated switch as the gas demand varies. It should be used only when the demand for gas will be intermittent. 

It is sometimes desirable to have a compressor equipped with both constant-speed and automatic-start-and-stop control. When this is done, a switch allows immediate selection of either type.

In contrast to the pulse method of determining subcriticality, which because of its labor-consumption and limited neutron tube lifetime is only used at considerable medium variations, the stationary method is used for constant and non-stop control of subcriticality.

A report describes a patient with myotonia, controlled with quinine, whose symptoms worsened within 3 weeks of starting to take rifampicin for the treatment of tuberculosis. Peak quinine levels were found to be low, but rose again when the rifampicin was stopped. Control of the myotonia was regained 6 weeks later. ... 

Stop controls should bring the equipment to a safe condition in a safe manner. Emergency stop controls are intended to effect a rapid response to potentially dangerous situations and should be easily reached and activated. Common types are mushroom-headed buttons (see Fig. 1.5), bars, levers, kick plates or pressure-sensitive cables. 

Markings - there are many instances where marking of equipment is appropriate for health and safety reasons, e.g. start/stop controls, safe working load on cranes or types of fire extinguishers. 

All wheels should be suitable for the work on which they will be used and the machine provided with conveniently positioned starting and stopping controls.
