    Abstract: The invention relates to an electronic control system for aggregates which generate compressed air or vacuums. The inventive system comprises programmable electronic circuits for controlling, regulating and monitoring the technical functions of aggregates of this type, especially the functions of the compressed air generator or the vacuum pump and the corresponding drive mechanisms, and air treatment. The aim of the invention is to provide a control system which will simplify construction (design), production, assembly, commissioning, maintenance, checks for defects and repairs despite the variety of different types of aggregates and the different conditions of use. To this end, the inventive electronic control system is configured as a standardized control system for use in a number of different aggregates for generating air pressure and/or vacuums and has an industrial PC or microcomputer which is monitored and controlled by an operating system and which has one or more microprocessors and a central data memory. The data memory contains at least control and regulation software as well as a number of aggregate-specific data profiles which are each provided for a particular type of aggregate and can be called up separately.

    Abstract: An in duct humidification and evaporative cooling system for industrial and commerical buildings is disclosed. Air and water under pressure are utilized to atomize water into minute droplets which rapidly evaporate and raise the level of relative humidity while producing evaporative cooling. A first relative humidity sensor/transmitter produces a signal proportional to the relative humidity of return air, and a second relative humidity sensor/transmitter provides a signal proportional to the relative humidity of supply air. Preset receiver-controllers external to the duct receive the two signals and send them to a low signal selector which in turn sends the lower signal to a modulating water valve and to an electrical switch which opens a valve in the pressurized air supply line. A second electrical switch operatively connected in the air supply line opens a valve in the pressurized water supply line. Air and water from the two supply lines are delivered to in duct air and water manifolds and to spray heads on the air manifold to maintain automatically the required humidification and cooling parameters.

    Abstract: A mixed air conditioning controller is formed as a factory assembled and adjusted unit in a compact housing, with simple and direct input/output field connectors. Various temperature and humidity input devices are field connected to produce a sequenced control of the air dampers and mechanical cooling and heating devices, as well as auxiliary devices. The controller includes a primary input related to room demand, an outside air temperature input, with an interlocked control to the damper, a fan status input, a minimum air supply control and a by-pass switch having a low limit input. The logic network connecting the input/output includes pneumatic switching, pressure selecting and comparing devices of a diaphragm-controlled-orifice construction connected to function as fluidic repeaters, pressure regulating valves and pressure isolating and switching devices. The controller includes a conditioning channel and a damper channel. An outside air interlock controls the damper channel and a presettable switch controls the minimum air supply control. The presettable switch also includes a low limit temperature signal input. An auxiliary output may drive a humidity controller having a conditioning channel and a humidity channel. The humidity controller includes an interlock network connected to transfer the humidity input signal to the conditioning channel and a switch means controlled by the auxiliary output of the temperature controller.

    Abstract: A safety governor operable on failure of the primary governor to arrest operation of the motor with which it is associated. An annular spring-washer, that includes weights supported peripherally distributed about its face, is secured to the drive spindle proximately displaced opposite inlet air passages to the motor. In response to centrifugal forces of rotation, the weights bend or deflect the spring-washer in an axial direction increasingly toward the inlet air passages until, at a predetermined overspeed, passage closure is effected interrupting air supply to the motor.
