Abstract: ELECTRONIC KEY TELEPHONE SYSTEM     Abstract of the Disclosure Each of the station sets in the system generates a continuous, current-modulated digital data stream carrying information concerning the status of pushbutton-actuated switches associated with a particular service or feature.          This data stream is transmitted via a phantom pair over standard four-wire cable to an associated station card in the key service unit, which receives and decodes the data, implements any service requested at the associated station set by closure of a pushbutton-actuated switch in the station set, and generates a continuous voltage-modulated digital data stream carrying instructions for the connection of the station set speakerphone to either the first or second talk path formed by the first and second conductor pairs in the standard four-wire cable, for energization of light-emitting diodes associated with the pushbutton-actuated switches in the station set, and for controlling background music transmission to the associated station set.  This data stream is transmitted via the aforementioned phantom pair to the station set, which receives and decodes the data and carries out the instructions contained therein.  Each station card and each station set incorporates a stored-program digital microcomputer  for de-coding the received data and for generating the data to be transmitted. Each station card also includes a series of cross-points in the form of field-effect transistors, the gate elec-trodes of which are connected to crosspoint latches controlled by the microcomputer.  Each crosspoint has an associated input terminal in a status multiplexer which receives data from the passive port to which the associated crosspoint is connected.          Each crosspoint and its associated status multiplexer input terminal constitute an active port. Each station card also includes at least one passive port for hotline connection to an active port of another station card or cards, and may also include a passive port for connection to the active ports of one or more link cards.  Other system component circuits are dis-posed on line cards having a single passive port, an internal conference card having a single passive port, a page card having multiple passive ports, a register card or cards con-nected to the link card or cards, and a tone generator card.

Abstract: TREATING PULP WITH OXYGEN                ABSTRACT OF THE DISCLOSURE           A wood pulp slurry is treated with oxygen in a mill with little change to the process or structure of the mill.  No special pressure tanks are required. The consistency of the pulp need not be altered for the treatment step.  It may be treated at the usual process consistency of the pulp; e.g., it may be treated at the usual consistency of the pulp leaving a washer or subse-quent steam mixer without additional dewatering or addi-tional dilution.          The oxygen is added into a closed section of the system so that it cannot immediately vent to the atmos-phere.  Alkali should also be present when the oxygen is mixed with the slurry.  The mixing should occur near to the point of oxygen addition.          The mixing occurs in a relatively small mixer (550) that intensively mixes the slurry and gas.  The mixer (550) has a mixing zone with a swept area of 10,000 to 1,000,000 square meters per metric ton of oven-dry pulp.  A preferred range is 25,000 to 150,000 square meters per metric ton of oven-dry pulp and an optimum range of around 65,400 square meters per metric ton of oven-dry pulp.          The pulp is treated several times during a sequence. Some sequences are O-X-O and O-O-X-O in which X may be chlorine, chlorine dioxide, a combination of chlorine and chlorine dioxide -mixture of chlorine and chlorine dioxide, CD, Dc -, hypochlorite, peroxide and ozone. The sequence may be followed by a D stage.          Specific mixer designs are also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE A bifurcated funnel presents small fish in alternating orientation to a canning apparatus.  The canning apparatus is moved incrementally forward to receive the oncoming fish by a distance equivalent to the width of that individual fish.  A flap is disposed in the funnel and each fish displaces the flap by a distance equivalent to its width. The flap is connected to a ratchet wheel which contains electrical contacts for actuating a plurality of solenoids which determine the position of a stop mechanism for the canning apparatus.  The distance of movement of the ratchet wheel is designed in ac-cordance with the size of the apparatus which is to receive the fish.  When the ratchet wheel moves its total allotted distance, a set of contacts resets the ratchet wheel and the canning apparatus.
