摘要： A changeable neon sign employs a series of symbol display modules, each of which is made up of a matrix of glow tubes; the individual elements which can be activated to produce any selected letter or numeral are caused to glow in the desired arrangement. A series of such modules is controlled to come on in desired sequence by a solid-state switching system which in turn is programmed by a tape control or reader system. The switching system, including a shift register, can present the input data as traveling copy. A digital input code can present other data.

摘要： A gas compression system including a body of fluid and a down pipe. A first end of the down pipe is positioned to receive a fluid from a source above a surface of the body of fluid and a second end is positioned at a lower level of the body of fluid. A gas inlet is coupled to the down pipe, above the surface of the body of fluid for mixing a gas to be compressed with the fluid from the source to form a mixture. A chamber is positioned at the lower level of the body of fluid and coupled to the second end of the down pipe for receiving the mixture and collecting a compressed gas therefrom. A conduit is coupled to the chamber for transferring the compressed gas therefrom.
