  • Patent number: 4210175
    Abstract: A fluid injection assembly of a type designed to inject fluid into a flowing stream of liquid at a predetermined, adjustable rate without the assistance of an outside power source other than the line pressure of the flowing stream itself. The assembly includes a casing having the fluid to be injected disposed therein and at least partially contained by a flexible membrane. Liquid from the flowing stream is partially disposed in fluid communication with the interior of the casing so as to flow in surrounding relation to a portion of the flexible membrane whereby pressure exerted thereon will aid in dispensing of the injection fluid therefrom. An open end of the dispensing line for the injection fluid is disposed within the flowing stream so as to create a negative pressure further aiding in removal of the fluid from within the casing. A liquid flow rate meter is provided so as to give a constant, visual indication of the rate of flow of the liquid into which it is desired to inject a fluid.

  • Patent number: 4205309
    Abstract: A character generator produces highly accurate electronic reproductions of characters of any chosen style on the screen of a CRT by simultaneously controlling the orientation, length and intensity of the strokes formed by the electron beam of the CRT. The character generator is coupled to an input source which periodically generates a character address signal representative of a selected character. A read only memory contains a plurality of multi-byte microprograms each located at a predetermined address. Twelve eight-bit bytes constitute a single microprogram which defines a single character. A single byte of a microprogram defines a single stroke of a character. A first three-bit element of each byte fully defines the magnitude and polarity of the X component of the stroke, while a second three-bit element of the byte defines the magnitude and polarity of the Y component of the stroke. The remaining two-bit element of the byte designates one of four available electron beam intensity levels.

  • Patent number: 4195483
    Abstract: An engine apparatus is adapted to operate upon partial immersion in a heated liquid in a liquid reservoir. A movably mounted frame is mounted to a fixed frame and located adjacent the liquid reservoir in a manner that heat exchangers attached to the movable frame are successively passed into the liquid of the liquid reservoir. The heat exchangers are connected in pairs on opposite sides of the movable frame and contain a low boiling point liquid therein. Each heat exchanger of each pair is connected to the other through a pair of drive cylinders, so that the expansion of the fluid in the heat exchanger passing through the liquid reservoir and the simultaneous contraction of fluid in the heat exchanger that has left the reservoir expands and contracts the drive cylinders to operate the engine. The engine will operate from a low temperature heated liquid such as may be provided by solar panels or water heat from power plants.
