A pneumatic control circuit for a pressure adsorption swing system having two three-way valves which are connected at one end to a compressor and at a second end to first and second molecular sieves respectively. The three-way valves and the compressor are both located on the inlet side of the sieves such that they form a single control circuit for both the adsorption/desorption phase and the balance phase of the pressure adsorption swing system. A method for controlling pneumatic flow in the pressure swing adsorption system is also described.

Pneumatic circuit control for pressure swing adsorption systems

A device treats sleep apnea by supplying pressurized air to the nasal passages of a user through a connection device connected to said control device through a hose. The device includes a blower which pressurizes air and which supplies the pressurized air to the connection device, and a control device adapted to control the pressure level supplied by the generating device. The control device incudes a ramp generating device adapted to selectively control the generating device to generate pressurized air at a pressure level which increases for a preset time to a preset prescribed pressure level, and an override device which, when actuated, overrides the ramp generating device and which controls the generating device to immediately generate pressurized air at the preset prescribed pressure level.

In an ultraviolet sterilizer unit a length of corrugated pipe is coiled into the shape of a helix around an ultraviolet germicidal source to maximize the exposure of the fluid media flowing in the pipe to the ultraviolet germicidal source. The pipe is formed of a tough, flexible fluorinated polyalkylene resin capable of being used without sidewall support, and has an internal groove.
