Abstract: An engine speed limiter includes a computing means for computing a value that is functionally related to the time between successive ignition pulses and for outputting a speed signal representative thereof. The speed limiter also includes generating means for generating a reference signal that is functionally related to the desired maximum limit speed. A comparison means compares the speed signal with the reference signal and generates a limit signal if the result of the comparison indicates that the actual engine speed is about equal to or greater than the desired maximum limit speed. The limit signal is used to interrupt engine ignition to thereby limit engine speed.

Abstract: There is disclosed an algorithm for use with a digitized image which provides a means of simulating a continuous tone image containing a range of gray shades from black to white or a color separation. The "threshold equation" is the key of the invention as it calculates a threshold gray value that is compared to the desired local image value to determine whether that particular point should be "on" or "off". Which points (spots) are "on" and which are "off is determined by the function that assigns a "threshold" value (the shade at which a pixel changes from "off" to "on") based on a pixels "x" and "y" coordinates.

Abstract: A thermo-electric laser temperature control apparatus is driven by a switching mode control circuit (317, 315). Driving current polarity (via 321 or 322) determines if the thermo-electric apparatus (305) is operating in a heat absorbent or heat generating mode. A sequencing control circuit (361-364) is used in association with the control circuit to define operative ranges of the thermo-electric temperature control apparatus consistent with maintaining proper temperature for a linear operative range for the laser. Feedback circuitry permits precision control of the converter output to limit the operative temperature range of the laser to a small precisely defined temperature window.

Abstract: Imbalances between currents to and from a remote point are detected by passing the outgoing currents and the return current through different, oppositely-oriented coils on a saturable core, and an excitation current is applied to another coil in the same core sufficient to drive the core into saturation in at least one direction. When the outgoing and return currents are the same, the excitation produces successive voltage pulses of the same durations, as measured by an up-down counter ; if an imbalance is present, the remainder in the up-down counter shows this. To detect excessively high imbalances, which might place the core always in saturation, another counter preferably senses the sum of the widths of successive pulses, and indicates an imbalance if this sum falls below a preselected threshold.

Abstract: Method for continuous recovery of starch from grain wherein the grain is dry milled and the flour obtained after separation of husk is mixed with water and the mixture obtained is homogenized. Directly after homogenization without intervening treatment steps the homogenized suspension is separated in a first decanter centrifugal step into a lighter fraction containing in additon to grains, solids, and fat also minor starch particles, which is removed from the process for use as feed and a heavier fraction comprising major starch particles. Said latter fraction is concentrated in a second decanter centrifugal step to a suspension having a solids content ranging from 40 to 60 %, which constitutes the final product of the process.
