Abstract: ABSTRACT       The disclosure relates to a key telephone system intercom line circuit which uses only three leads to connect plural telephones and an intercom line control circuit.  These leads comprise two talking circuit leads and one control lead. Exclusion circuits in each of the telephones are controlled by signals applied on the single control lead (1) to allow a telephone to seize the intercom line circuit when it is in an idle state, (2) to allow a called telephone (signaled via a separate pair of calling leads) to answer without being ex-cluded and (3) to exclude all other telephones from the intercom line circuit after the calling telephone has seized the intercom line circuit.  Indicators in each telephone associated with particular intercom line circuits provide a visual signal at each telephone set concerning the status of the intercom line circuit by (1) not being lit when the intercom line circuit is in an idle state (2) flashing periodically when  the intercom line circuit is in the seized state and (3) being continuously lit when the intercom line is in a talking state.

Abstract: CONNECTION FOR SECURING A HELICALLY   CONVOLUTED HOSE TO A HOSE FITTING               Abstract of the Disclosure A connection for securing one end of a helically con-voluted suction hose to a hose fitting such as is used to effect rapid engagement of the hose with or disengagement thereof from the suction inlet of a vacuum cleaner.  The fitting includes a tubular portion having external threads of the same pitch as the unstressed convolutions of the hose so that the tubular portion can be threaded into the end of the hose.  The cross sectional configuration of the threads is such as to resist relative ro-tation between the fitting and the end of the hose when the threads are engaged with the hose convolutions,  Additional re-sistance to relative rotation between the fitting and end of the hose is provided by a collar at the inner end of the tubular por-tion, the collar serving as an abutment to cause compression and a reduction in the pitch of the convolutions of the hose between the threads and collar with continued threading of the fitting into the end of the hose after the end edge of the hose has en-gaged the collar.  Barbs on the threads substantially increase the resistance to rotation of the fitting relative to the end of the hose in a direction to effect unthreading of these parts, the barbs being provided by sharp transverse edges and corners on the threads.  Removal of the remnant of the hose remaining on the tubu-lar portion after the hose has been severed adjacent to the end of the tubular portion in order to replace or repair the hose is facil itated by interrupted portions of the threads, such interrupted portions permitting axial slitting of the hose remnant and removal thereof from the tubular portion.

Abstract: APPARATUS AND METHOD FOR     POPPING CORN     ABSTRACT           A short cycle corn popping apparatus having a transparent bowl shaped cover interfitted on a base.  Mounted in the base is a pan defining a popping surface of circular configuration. Agitating mechanism including a stir rod, a spring tensioned drive assembly and motor is associated with the pan to agitate corn on the popping surface.  The stir rod is held in a proper position for stirring by being biased against an annular boss formed on the popping surface and has a radius shorter than the popping surface to avoid jamming.  The pan includes an inclined surface to return unpopped corn to the popping region.  Tempera-ture regulated heating mechanism defining an annular heating channel heats a selected outer annular portion of the pan's popping surface to pop corn by such method.  The popper is de-signed against oil leakage into its base, and has its motor shielded and insulated from heat and mounted outside of the popper's heated region.  The top of the cover has a butter well associated therewith that utilizes steam generated in the popper to melt butter and butter corn as it is popped.  Handle structure is formed on the popper for turning the popper over once corn has been popped and the cover is designed to serve as a serving bowl.

Abstract: ACCELERATION ENRICHMENT FOR CLOSED LOOP CONTROL SYSTEMS            ABSTRACT OF THE DISCLOSURE          An acceleration enrichment feature for a closed loop fuel management system  controlling the air/fuel mixture delivered to an internal combustion engine to regulate the roughness of the engine at a predetermined level. The enrichment feature provides increased fuel to the engine for operator induced transient conditions proportionately by sensing the rate of change of throttle angle.  A throttle angle position signal is modified by circuitry providing a transfer function that introduces a lag term into the throttle angle position signal while differentiating the signal to determine the rate of change of throttle angle.  The modified throttle angle position signal is additionally corrected by the amount of roughness sensed by the closed loop control and enriched for rough operations of the engine beyond a threshold and leaned for smooth operations of the engine.  Acceleration enrichment pulses of a frequency dependent on the magnitude of the corrected throttle position signal are then combined with the basic fuel injection pulses of the closed loop fuel management system to provide a desired A/F ratio during operator induced transients.

Abstract: CONTINUOUS PROCESS FOR SEPARATING HIGH BOILING, HEAT SENSITIVE MATERIALS     ABSTRACT OF THE DISCLOSURE           This invention is concerned with a continuous process for separating higher boiling, heat sensitive com-ponents from a liquid-product stream.  It involves a rapid evaporation of the desired product of the stream in an evaporator which minimizes residence time, such as a falling film evaporator, and feeding the vapors and the remainder of the stream to a separation column where the vaporized products rise in the column.  Part of the vaporized products are removed after condensation and then recycled back to the column as reflux.  This reflux after contacting one or more trays is collected and recycled to the evaporator and mixed with the product feed being treated.  The liquid reminder of the feed stream is collected at the bottom of the column.  the bottom of the column can be kept at a temperature which minimizes any breakdown of the heat sensitive components present therein and, if desired, the bottoms in the column can be quickly withdrawn for treatment elsewhere or for recycling back to the process.  A desirable embodiment is to recycle a portion of the residue at the bottom of the column back to the evaporator.                S P E C I F I C A T I O N
