Abstract: VENTILATING APPARATUS                 Abstract of the Disclosure Ventilating apparatus having an exhaust hood for mounting in a room and normally above a stove, grill, or other apparatus from which fumes arise.  Ambient air from outside the room being ventilated is forced into an insulated intake chamber through a relatively narrow longitudinal slot at the bottom of the intake chamber, thence directed rear-wardly and upwardly across a fume collection chamber, through a grease filter, and into an exhaust chamber from which the fumes are exhausted to the atmosphere by a fan.          The outside air is forced through the slot in a fast moving narrow stream to form an air curtain across the fume collec-tion chamber with minimal mixing of the fume laden air and the air curtain.  Tempered air is introduced into the room being ventilated adjacent the exhaust hood to provide a minimum influx of tempered air from the room being ventilated into the hood to prevent dissipation fumes into the room, and to facilitate collection of such fume laden air by the exhaust hood.

Abstract: METHOD AND APPARATUS FOR    HANDLING OFF-GASES FROM METAL REFINING VESSEL                 ABSTRACT OF THE DISCLOSURE     The mouth of a metal refining vessel has a primary gas collection hood supported over it.  A duct couples the hood to a gas cleaning quencher which is serially connected by a duct to a wet scrubber.  A fan draws gases and suspended particulates through the system and discharges the effluent from the scrubber to a stack which burns the gas in the atmosphere.  A secondary gas collection hood is supported over the first hood.  The secondary hood has a duct which connects into the gas cleaning system intermediate the quencher and the scrubber.  A bell damper connects the duct from the secondary hood into the inter-mediate duct.  When the vessel is tilted away from the primary hood, the damper is opened so that gases escaping from the mouth of the vessel may be captured by the secondary hood and passed through the gas cleaning system.  The secondary hood has a chain curtain which yields to allow a ladle or scrap charging box to-swing over the vessel mouth when it is tilted.

Abstract: APPARATUS AND METHOD FOR SWITCHING OF DATA          Abstract of the Disclosure Apparatus and method for carrying out data switching; e.g. at a store-and-forward exchange node in a data communication network.  Plural processors operate relative to multiple ports and traffic storage queues, partially on an exclusive basis and partially on a shared basis, to effectuate switching of data traffic with balanced sharing of the aggregate processing load.  The processors control traffic processing functions (reception, storage and output transfer) on a varied assignment schedule.  Supervisory signals exchanged between processors indicate status and destinations of currently stored traffic loads.  The scheduling of output traffic to ports is handled by individual processors on an exclusive assignment basis.  When a port is available to handle a given traffic segment (packet) destined for that port the respective processor having exclusive output scheduling responsibility for that port signals such availability to the processor having current res-ponsibility over the transfer of said segment.  The latter processor then executes the operations required to complete the transfer.

Abstract: CHEMICAL WASTE WATER TREATMENT METHOD          Abstract of Disclosure A method of treating domestic, commercial or industrial waste water which includes the steps of mixing the waste water with a coagulant aid so as to bring the pH of the mixture to within a range of about 9.0-10.5, and thereafter adding precipitating agents in at least two successive steps so as to lower the pH of the mixture by about one unit for each step and thereby precipitate solids therefrom until the mixture is approximately neutral.  After the addition of each precipi-tating agent, the precipitated solids are separated from the waste water effluent before the next succeeding precipitating agent is added.  Preferably two such successive precipitation steps are performed, after which the resultant waste water effluent is treated with an oxidizing and disinfecting agent, filtered, and then treated with a further oxidizing and disinfecting agent to minimize the B.O.D. level.  In the course of the process, a portion of the solids separated from the waste water effluent in the respective steps is preferably recycled into the treatment system by mixing it with new incoming waste water to partially take the place of the original coagulant aid.  The preferred coagulant aid utilized is portland cement, with aluminum sulfate and copper sulfate preferably being used in sequence as the precipitating agents and potassium permanganate and ozone being used in sequence as the oxidizing and disinfecting agents.
