Abstract: A PULSE CODE MODULATED DIGITAL    AUTOMATIC BRANCH EXCHANGE     Abstract of the Disclosure A pulse code modulated digital automatic branch exchange for a telephone network or other communication network has a multiplicity of N input/output ports connected to an input/output system comprising a plurality of multiplexers that each scan a small group of ports in a predetermined cycle; output signals from the multiplexers are converted into M-bit parallel digital data signals and recorded in an input data store at a location identified with the port of origin.  The input data store is scanned, by a fully bused synchronous transfer system, in accordance with a predetermined transfer time cycle having at least N fixed transfer time slots, one for each communication port; during the transfer time slot for any port, data recorded in the input store from that port is transferred, via an M-digit paralel data bus, to a location in an output data store associated with another port for which that data is destined.          From the output store the data signals are supplied to a reverse converter and then to de-multiplexers, all part of the input/output system, connected back to the input/output ports.  Sequence control circuits control the timing of operations within the transfer system to correlate the transfer of data, during a call between any two ports, so that the transfer time slot for each port in a given call becomes the input time slot for that port and the output time slot for the other port.  Hook switch information, tone data, port identification data, and all other control information is bused throughout the transfer system of the exchange.  For networks in which data is already in digital form, the conversion stages may be required to translate from serial to parallel form or from one digital format to another, as contrasted with the analog-to-digital conversion required for audio circuits. The input and output stores may be combined in a unified input/output store.

Abstract: TIRE PRESSURE COMMUNICATION DEVICES                  ABSTRACT OF THE DISCLOSURE           Disclosed are devices for transmitting signals from a rotatable tire to a stationary recei-ver which correspond to the internal pressure of the tire.  In one embodiment, a Bourdon tube communicates with internal tire pressure to regulate the magnetic gap of an electromagnetic induction configuration. Changes in the magnetic gap result in corresponding changes in an output signal strength.  In another embodiment of the invention, a bellows is provided in communication with tire pressure for regulating the position of the core of an LVDT.  The core position and, accordingly, the output of the LVDT corresponds to tire pressure.  In yet another embodiment, strain gauges or other appropriate electrical signal genera tors are connected to the tire and interconnected with a rotating race.  A plurality of ball bearings are maintained in a preloaded condition between the rotating race and a stationary race, the latter race communicating signals to a tire pressure meter or the like.

Abstract: Suspended Seat Assembly Abstract This invention relates to a suspended seat assembly which eliminates the problems of excessive elevational movement and limited field of use, harsh ride, inability to accommodate a broad range of occupant weights, bulkiness, wear and premature failure, and difficult adjustment.  The suspended seat assembly has a seat frame, a support frame, a connecting apparatus which pivotally connects the seat frame to the support frame and permits movement of the seat frame between a first position above the support frame, past the support frame, to a second position below the support frame, a tie apparatus which maintains the seat frame at a preselected attitude relative to the support frame, and a biasing arrangement for biasing the connecting apparatus and urging the seat frame to the first position.  Thus, the suspended seat assembly useable in vehicle applications wherein low overhead requirements are required, improves ride, accommodates a broad range of occupant weight, is compact, easy to adjust and has improved life.  The suspended seat assembly is particularly useful in a material handling vehicle.

Abstract: ABSTRACT        An ink jet printing system suited to the making of large scale graphics, such as outdoor billboards, includes an endless carrier for moving a plurality of rigid flat panels, onto which a graphic is to be printed in sections, repetitively past an ink jet printing sta-tion.  At the printing station each panel moves in purely rectilinear fashion in a direction parallel to its ink drop receiving face so that such face remains essentially at a uniform spacing from the ink jet printing heads of the printing station as the printing occurs.  A means for timing the operation of the ink jet heads takes into account irregularities or changes in the motion of the panels past the printing station so that the ink drops are correctly placed despite such irregularities or changes. me ink jet heads can eject relatively large drops of pigmented ink.  In the case of polychromatic half-tone printing, for each pixel of a panel different colors are printed at substantially different times so that the printed ink drops of one color can dry before those of another color are printed, and a heating means may be used to enhance the drying.
