Abstract: DRAG FLOW METER                 ABSTRACT OF THE DISCLOSURE           A drag-type flow meter is disclosed of the type having a drag plate disposed in the fluid flow stream, the velocity of which is to be measured,  The drag plate is mounted on a cantilevered arm which is pivotally mounted externally of the fluid flow passage, with a tensioned wire counteracting the drag force tending to pivot the arm.  The tensioned wire is disposed in a magnetic field and an electrical current is passed through the wire to cause vibration of the wire, the frequency of which varies linearly with the drag force exerted on the drag plate due to the corresponding change in wire tension.  Varying frequency of the current provides a digital electrical signal which varies linearly with fluid flow velocity.  Embodiments are described enclosing the wire mounting components in a vacuum housing in order to minimize the air damping of the wire vibration, and a mounting arrangement minimizing the effects of temperature variation on the output signal,

Abstract: ABSTRACT OF THE DISCLOSURE    A time-division multiplexing method and device for combining a data signal and several secondary binary sig-nals into a train of pulses, whereby data signals can be transmitted at various bit rates in synchronous of asyn-chronous mode.  In the multiplexing method of the present invention, the data signal and N secondary signals are multiplexed together using two different frames respect-ively termed "synchronous frame" and "asynchronous frame", depending on whether data transmission is to be performed in synchronous or asynchronous mode.  The asynchronous frame comprises a frame-alignment bit having a predetermined value, a data bit, and N bits pertaining respectively to the N secondary signals.  The synchronous frame is divided up into n subframes, ?1 bits in length each, where n is equal to the integer that is immediately larger than the quantity N/(?1-2).  Length ?1 is defined by the relation ?1 + LR/DR, where LR is the fixed bit rate for the pulse train resulting from the multiplexing process and DR is the bit rate for the data signal.  Each subframe includes a synchronization bit whose value is complementary to that of the frame alignment bit, a data bit, and several bits pertaining respectively to the secondary signals.  In addi-tion, the last subframe includes a frame-alignment bit Each bit with a synchronous or asynchronous frame is asso-ciated with a control bit which has a first predetermined value when it is associated with a synchronization bit or a frame-alignment bit, and the complementary value when it is associated with a data bit or with a bit pertaining to the secondary signals.  All of the frame bits together with the associated control bits are then encoded to be simul-taneously transmitted over the transmission path.  The frame bits define a data channel designated A, and the control bits define another channel designated B.  The bits are paired off, with each pair comprising a channel A bit and the channel B bit associated therewith, and each of these pairs is encoded for transmission over the line.  The invention also provides the demultiplexing method associated with the multiplexing method described above.  The invention further provides an interface transmitter and an interface receiver embodying the methods described above and allowing various DTE to exchange data, control and timing signals.
