Abstract: INFRA-RED DATA COMMUNICATIONS SYSTEM FOR       COUPLING A BATTERY POWERED DATA ENTRY DEVICE                  TO A MICROCOMPUTER             Abstract A battery powered keyboard entry device includes an infra-red generator for coupling the device to a microcomputer which includes an infra-red receiver Each input binary signal is transmitted as a few (e.g. two or three) short infra-red pulses indicating the leading edge of the binary signal.  In the receiver, the received groups of pulses, after detection and amplification, are stretched by a single-shot circuit to produce binary signals of substantially the same length as the original binary signals.  As each transmission is substantially shorter than each binary signal, power consumption in the keyboard entry device is substantially reduced as compared with a system in which the infra-red pulses for each input signal extend over the input signal length.

Abstract: Abstract A loading apparatus for loading feed stock into agricultural bags wherein the loading apparatus has a housing with a hopper, a passageway communicating with the hopper and a tunnel communicating with the passage-way.  The tunnel supports the open mouth of an agricul-tural bag to be filled.  A rotor is drivingly located in the passageway.  The rotor and passageway have widths approximately two thirds the width of the tunnel.  The tunnel has an expanding chamber, a forming chamber and a guide member.  The expanding chamber has a rear wall extending substantially vertically and has side walls diverging outwardly all with the view to accommodating the mass of feed stock received from the rotor in the passageway.  The rotor has flanges on the ends within the passageway and mount plural pairs of teeth spaced about the circumference thereof.  The relatively short rotor is driven at relatively high speeds, which when combined with the pairs of teeth moves the feed stock rapidly and effectively into the tunnel where it fills the tunnel before discharge into the bag.  Brakes are provided on the wheels on the housing which brakes are preloaded so that build-up of pressure of material between the closed end of the bag and the tunnel will advance the loading apparatus to deposit the compacted feed stock in the bag.

Abstract: SELF-ROUTING PACKETS WITH STAGE   ADDRESS IDENTIFYING FIELDS Abstract A multi-stage packet switching network comprising a plurality of packet switch nodes for communicating broadcast and non-broadcast packets each comprising stage identification information and sets of routing information. Each node responsive to receipt of one of the packets for decoding the stage identification information to determine if the packet is a broadcast or a non-broadcast packet.  If a broadcast packet has been received, the switch node transmits this packet to the next sequential stage on all output links interconnecting the switch node to the next sequential stage.  If the packet is of the non-broadcast type, the switch node decodes the stage identification field to determine which of the sets of the routing information is to be used for routing the non-broadcast packet to the next sequential stage.  Before routing the non-broadcast packet to the next sequential stage, the switch node increments the stage identification field.  The switch node contains the necessary circuits for performing the incrementing of the stage identification field of a non-broadcast packet and for bypassing the adder circuit for a non-stage identification information portions of the packet and for bypassing the adder circuit for stage identification field of the broadcast packet.
