Title: Real time digital signal processor idle indicator
Inventor: VEA MATTHEW J J
IPC: G06F11/34
Filed: 1988-05-18
Granted: 1992-03-24
Abstract: ABSTRACT OF THE DISCLOSURE      Instructions in the processor idle loop are used to measure the percentage of time the processor is at idle.  The processor idle loop instructions control the processor to alternate a processor data output between output states.  The processor data output thus alternates between states whenever the processor is idle, and remains in the same state when the processor is performing useful tasks.  A frequency counter or other indicating device responsive to the rate of processor data output state change directly indicates the amount of time the processor is idle relative to the total amount of processing time. Since the change of state, not the state itself, of the data output is detected, it does not matter what state the data output is left in when the processor is interrupted from performing the idle loop instructions.

Title: Slag detector apparatus for molten steel process control
Inventor: HUMMERT GEORGE T
IPC: B22D11/10
Filed: 1988-09-01
Granted: 1992-01-28
Abstract: -20-              W.E. 53,993 ABSTRACT OF THE DISCLOSURE            A  slag  detector  apparatus  is  capable  of detecting a condition of 5% or less slag entrainment in a molten metal stream so that actions can then be taken to shut off further discharge of the molten metal from the ladle to the tundish in a continuous casting line.          The  molten  metal  stream  has  a  fluctuating cross-sectional  dimension  and is  composed of  a continuous succession  of  recurring  cyclical  globules  of molten metal. The slag detector apparatus employs a coil having an axial length at least equal to the length of each globule  of  molten metal in the stream therof.  The impedance  of  the  stream  due to entrainment of slag therein is reflected in the terminal impedance of the coil.  An  impedance detector is employed for periodic sampling  and  smoothing  of  the  fluctuations  of  the terminal impedance of the detector coil. The detector coil  of  the  apparatus  is  included  in  a  signal sensitivity enhancement circuit which also includes a tunable capacitor connected with the detector coil. The capacitor  is  used  for  tuning  the  circuit  to  its resonance frequency so that the capacitive reactance of the circuit due to the presence of the capacitor cancels the inductive reactance of the circuit due to the presence of the coil so as to leave only an impedance that is due to resistance of the coil.

Granted: 1995-12-05
Abstract: There is disclosed a safety device for shutting off the power supply to a food heating appliance, typically a stove or range,  or detection of a condition,  such as smoke, indicative of burning food.  The device includes a switch for location in the power supply circuit between the power supply source and a range,  a  sensor such as  a  smoke detector for location n the vicinity of the appliance for activation when smoke is detected,  and an actuator for opening the switch on activation of the smoke detector.  If food begins to burn on the stove, this activates the smoke detector which in turn causes the actuator to open the switch and shut off the power supply to the range.  This stops or at least reduces the heating action of the range to prevent further burning of the food.

Abstract: SLUDGE DEWATERING AND DESTRUCTION  WITHIN A DELAYED COKING PROCESS          Abstract of the Disclosure Wet refinery sludges are disposed of by feeding them into a delayed coking process.  The sludge is fed to the blowdown drum of the delayed coking process and mixed with oil condensed from the coke drum overhead, and the resulting sludge-oil mixture is fed to the coke drum where it is converted into coke.   In order to remove the water from the sludge, a portion of the sludge-oil mixture is heated and recirculated to the blowdown drum where it provides the heat for drying and heating the sludge.   The recirculating sludge-oil mixture is heated by a low level heat source, such as one of  the fluid streams  taken off  from  the fractionator.

Abstract: Abstract of the Disclosure A method and apparatus are disclosed for printing and applying labels to packages which can vary in height over a large range, for example from a minimum height of 0.5 inches to and including a maximum height of 5.5 inches.  A label applier is pivotally mounted and gravity biased toward a lowermost position adjacent a package conveyor with the label applier being upwardly pivoted by packages passing thereunder to accommodate the wide range of package heights.  Packages are sensed on the conveyor as they move toward the label applier which prints and holds labels with the adhesive coated sides of the labels unexposed until the expiration of periods of time based upon package sensing. By timing label application to occur upon the expiration of such time periods, the labels are applied to preferred areas of the upper surfaces of the packages adjacent either the leading side edges or the trailing side edges of the packages as defined by direction of package conveyance.  The label applier also can move laterally relative to the package conveyor to further define the preferred areas of label application on the top surfaces of the packages.

Abstract: ABSTRACT           A  mask-free  method  is  disclosed  for  applying  a moisture-proof insulative coating to selected areas of a printed circuit board without applying the coating to regions that are to remain uncoated.  This method includes the step of supplying the insulative liquid coating to a flat-pattern nozzle means at a pressure to produce a liquid film emission in a flat triangular shaped pattern with a lower horizontal base edge, an upper apex, and substantially free of atomized particles of coating.   The nozzle means and  a  circuit board are positioned at a specific distance relative one another to place the board in the path of the flat triangular shape liquid film pattern.  Relative movement between  the nozzle means  and  circuit  board is effected in a generally transverse direction to the plane of the flat pattern and the liquid coating supply is controlled during the relative movement in order to supply liquid to the nozzle means when the flat pattern is directed toward the selected area to be coated and to interrupt the supply of liquid to the nozzle means when the flat pattern is directed toward regions to be left uncoated.
