Abstract: ASPIRATOR FOR AN INK JET PRINTER                   Abstract Disclosed is the design for an aspirator (10) of a continuous stream ink jet printer.  With reference to Fig. 1, the aspirator includes a tunnel configur-ation (20) wherein the tunnel cross-sectional area diverges from the inlet (23) to the outlet (22), the axial area gradient being inversely proportional to the intended velocity of air through the tunnel (20) so that the cross-sectional area of the outlet (22) is greater than the cross-sectional area of the inlet (23). In this manner, air movement through the tunnel (20) is substantially constant.

Abstract: ABSTRACT OF THE DISCLOSURE          A control system for electronic discharge machining includes an automatic relay control and a current cutoff control of particular interest.  The automatic relay control controls the energy level of machining pulses as a step function of machining cycle period by cutting in or out resistors in a power circuit through the machining gap Higher frequency pulses are held to a lower current level to avoid power transistor overload.  The relay control circuit includes multivibrators, energized at progressively nigher values of pulse period by the counters, and an output circuit for each multivibrator which controls one of the relays which vary the gap circuit resistance.  The relay control circuit also includes a threshold responsive circuit which senses any change in the several relay controlling output signals and acts to interrupt machining pulses briefly to allow time for relay operation.  The current cutoff control circuit detects abnormally low voltage across the machining gap and reduces gap discharge energy level.  Pulses referred to as "probe pulses" replace the normal master pulses to control gap discharge time duration and time spacing.  A logic circuit controls probe pulse duration relative to master pulse duration.  It provides for further lowering probe pulse energy by squelching probe pulses periodically if the master pulse period is below a certain time.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus for indicating the relative degree positioning between mechanisms in a glassware forming machine is disclosed.  Pulse generators are connected to those forming mechanisms which are desired to be monitored.  A clock pulse source generates three hundred sixty clock pulses for each machine cycle and the pulse generators generate one reset pulse for every 360° of monitored forming means cycle,  A switch means is provided for selecting the outputs of two of the pulse generators to be compared. The pulses generated by these selected generators are fed to a counter/display circuit having three inputs.  A clock input receives the clock pulses generated by the clock pulse source,  A clear input receives the reset pulse from the first selected generator.  An enable input receives the reset pulse from the second selected generator.  The counter/display circuit counts the number of clock pulses received between the clear and enable pulses. The number of counted clock pulses represents the relative degree positioning between the selected forming mechanisms and can be displayed on a digital visual display.  Alternatively, the counter/display circuit can receive pulses from a real time clock circuit and a selected forming operation generator to generate a display of operations per unit time, such as bottles per minute.

Abstract: A B S T R A C T      Method and apparatus for filling polygons displayed by a color CRT monitor of a raster graphic system.  A graphic controller produces control signals which control the mode of operation of the system, two of which are a fast polygon write mode and a display fast-fill mode.  When the system is in the polygon fast-fill write mode, the graphic controller reads fast-fill toggle bits from a frame memory of boundary pixels defining initial and terminal pixels of each fill element.  The fast-fill toggle bits of boundary pixels are set if the toggle bit read from memory was not set and, if set, it will reset it.  In the display fast-fill mode, the system senses the initial boundary pixel of each fill element by its fast-fill toggle bit being set and applies the color address of the initial boundary pixel to a color look-up memory until the terminal pixel of the fill element is read from the memory.  Thereafter, the color address of each pixel of a horizontal scan line is applied to the color look-up memory in synchronization with the raster scan until another initial boundary pixel of another fill element is sensed, etc., or until the end of the horizontal scan line is reached.

Abstract: ABSTRACT An interference detection circuit operable to switch a channel to another frequency when interference is detected is described.  The invention is based on the known fact that, when two carrier waves allotted the same frequency cause interference, a beat signal is obtained.  This beat signal can be amplitude detected but care must be taken to ensure that the amplitude fluctuation measured is due to interference and not due simply to the non-linearity of the transmission system which introduces amplitude modulation during conversation.  The invention, therefore, involves measuring the ampli-tude fluctuation resulting when the carrier wave is not being modulated to give a true indication of interference when the fluctuation exceeds a predeter-mined value.  A discriminator in the form of a voice level detector is used to operate a gate when there is no voice signal.  The gate can be placed at the end of the circuit, i.e., after the amplitude fluctuation level has been obtained, or it can be placed before the amplitude fluctuation circuit in which case it operates as an analog gate permitting passage of the beat signal only when there is no voice signal.

In order to improve the coding efficiency, a zone number difference is used instead of the zone number.  Furthermore, the direction of the difference vector is expressed by a quadrant which includes this difference vector.
