Abstract: A Microprocessor controlled timer particularly adapted for control of an animal feeder with a display of program items and with user settable feeding times and duration of such feeding times based upon the microprocessor calculated sunrise and sunset times with a selector switch and a change switch and display of program items allowing user reprogramming of the timer; the timer being broadly usable for activation of electrical equipment when desirable activation is at times relative to sunrise and sunset and also being usable for activation of electrical equipment according to normal clock time.

Abstract: An advanced turbo compound engine of internal combustion type having conventional reciprocally movable pistons, cylinders, manifolds, fuel-oxygen admixing apparatus or fuel injection, firing apparatus or compression ignition, and incorporating the improvement of respective nozzle means for conveying the hot, moderately high pressure combustion products (exhaust gases) from the respective cylinders to one or more turbines, the nozzle means having its inlet and discharge ends connected, respectively, with the respective boundary walls of respective combustion chambers or cylinders and with the inlet to a turbine. The turbine may have its shaft connected with a compressor for compressing at least air for intake to the engine and/or for connecting with the output shaft of the engine for assisting in delivering power that is used as desired, or connected to other auxiliary power needs.
