  • Patent number: 4115848
    Abstract: In a method and system of controlling the operation of a plant by means of an electronic computer, the judging conditions and control and supervisory operations corresponding thereto are described in tables from which a plurality of action lists having a standard form of plant state judging conditions plus controlling and supervisory operations are prepared. The contents of the action list are stored in the memory device of the computer. A process signal corresponding to a state of the plant is compared with a reference signal for producing a trigger signal which is used to select a corresponding action list. The content of the selected action list is judged to produce a control signal for controlling the plant.

  • Patent number: 4092721
    Abstract: Apparatus for controlling and adjusting the weight of doses of a loose product in a rotating metering head having telescoping volumetric members distributed therearound. The apparatus includes a rotating control head having a set of sample telescoping volumetric members. A main duct feeds the product to the metering head. A secondary duct is branched off the main duct to feed the control head. A scale is operative to receive individual sample doses as provided by the telescoping members of the control head and to discharge them, after the weighing thereof has been completed, to the metering head. A control assembly adjusts in a concurrent proportional mode the volume of the telescoping members of the metering and control heads according to the weight variations of the weighed product versus the scale reference value.

  • Patent number: 4090240
    Abstract: A method of preparing a program for numerically controlled machine tools is disclosed involving the use of an aid comprised of a model representing the workpiece to be machined and the tooling to perform the machining process, mounted to have a capability for relative movement along axes corresponding to the relative movement occurring during the machining process. Standardized preset tools and tool holders are established for use in the actual machining processes and corresponding model representations of such standardized preset tools and tool holder combinations are provided which can be located in the model in the same relative position as the corresponding actual tools and tool holders will be located in the machine tool. In preparing the NC program, a machinist prepares a machining process, selecting tools and holders from the available standardized preset tools, and specifies the various machining steps, spindle speeds, in-feed rates, etc. to be utilized in machining the workpiece.

  • Patent number: 4079235
    Abstract: A computer numerical control system for controlling a lathe or similar machine tool in the cutting of threads. One computer is used as an interpolator to produce speed commands in real time for producing a smooth cutting tool motion. A second computer is used as an axis controller for receiving said speed commands and for controlling the servo circuits of up to six machine tool axes. A resolver attached to the rotating spindle is utilized to synthesize a tachonometric signal, and is also connected to an interrupt circuit to measure the spindle speed and position. The interpolator then uses this spindle information to synchronize the cutting tool motion with the spindle angular speed and position to enable multiple passes of the cutting tool along the same thread line.

  • Patent number: 4077062
    Abstract: A night visual aircraft system receives flight data from an aircraft simulator, and terrain data (such as light points) from the gaming area data base. A computer within the night visual system organizes this image data by frame in a buffer memory according to a particular format of addresses, sequences, and bit places.An image processor receives the formatted image data to account for the position and orientation of the aircraft relative to the light points, and then projects the data into two dimensions for display. An image generator processes the projected data to provide analog inputs to a CRT window display in the simulated aircraft. The deflection input has X and Y voltages which calligraphically position the beam for simulating light points. A blank time increment computer blanks the CRT screen as the beam moves from each displayed light point to the next light point to be displayed. The blank time is sufficient to permit post-deflection settling.
