    摘要: The invention relates to a piston arrangement for a dual-stage piston compressor, comprising a cranksbaft and several cylinders which house the operating piston. Said arrangement allows two or more low-pressure stages and at least one high-pressure stage to be formed. The invention is characterized in that the two or more low-pressure cylinders are arranged in relation to the high-pressure stage in such a way that said two or more low-pressure cylinders are in phase or are offset by less than ±15° and compress in a position which is offset by 180°±20, in relation to one or more high-pressure cylinders.

    摘要: An interactive graphical application program combines a graphical command language and a control program to enable a user to graphically select and generate an automation sequence to control an automation application. A computer system stores a first program containing flow sequences and a set of controls representing possible hardware for use in the automation application. Structure is graphically displayed depicting each sequence step and transition to the next step in accordance with user selections. The first program is automatically linked with the controls to enable an application software program to be generated in response to user commands.
