Title: Improvements in or relating to automatic stop mechanisms for use with telegraph printers
IPC: H04L12/02
Filed: 1958-01-24
Abstract: 865,566. Type-printing telegraphy. TELEPRINTER CORPORATION. Jan. 24, 1958 [Feb. 18, 1957], No. 2521/58. Class 40(3) Automatic stop mechanism for a teleprinter having a driving motor which operates continuously during normal signal traffic or reception and a reset part operating only in response to incoming signals comprises speed-reduction gearing driven by the motor and terminating in a movable member controlled by a releasable friction driving member to operate a switch, restoring means urging the movable member in a direction opposite to that in which it is urged by the motor, a circuit including the switch which is operated to stop the motor by movement of the movable member for a predetermined time, and means connecting the reset part to the friction driving member to release the same in response to substantially any incoming signal. The operative circuit 60, 62 of the motor M is completed over closed contacts 56 of a relay 54 in series with a normally open switch 16 in parallel with the line receiving-relay 152. The switch 16 is operated by an arm 36 pivoted at 38 and carrying a friction-faced bar 12 engaging between a friction drive roller 34 and a pressure roller 14 carried on a bell-crank 42 pivoted at 41. The end of one arm of the bell-crank 42 is engaged by a projection 50 on an arm secured to the shaft 26 which is rocked anticlockwise during the printing of a character by a receiver which is of the form described in Specification 799,956. The roller 34 is driven through reduction gearing 24, 26, 28, 30 from a worm and worm-wheel gear 20, 22 driven from the shaft 90 connected to the driving motor M. During signal reception the actuation of the printing shaft 216 rocks the lever 42 and friction roller 14 so that the arm 12 and lever 36 are free to return to their normal position under the action of a spring 18. When signals have ceased for a predetermined period the downward movement of the bar 12 and arm 36 closes the contacts of the switch 16 so that relay 54 energized by the stop or rest condition on the signal line 150 opens contacts 56 to stop the motor M. The start impulse of a received code combination opens the circuit of relay 54 which releases to reclose the circuit of the motor M, and the actuation of the printing shaft 216 rocks the lever 42 so that the bar 12 moves upwardly and opens the contacts of the switch 16. The start impulse for the resumption of signalling should persist until the operation of first printing cycle. The signal-free period for the operation of the switch 16 can be adjusted by the pointer 64 which acts as a stop member for the arm 36, and scales 72, 74, 76 are provided for predetermined time periods corresponding to different signal transmission rates. The bell-crank member, corresponding to 42, Fig. 2, may be operated clockwise for release of the switch operating arm, Fig. 6 (not shown), and the incorporation of the switch mechanism in the printer shown in Specification 813,081 is indicated in Fig. 7 (not shown).

Title: Measurement of fluid flow rates
IPC: G01F1/7082
Filed: 1971-01-19
Abstract: 1359151 Ultrasonic flow meters; phase detectors J COULTHARD 6 July 1971 [6 July 1970 19 Jan 1971] 32563/70 and 2593/71 Headings H3A and H4D A fluid flow rate measuring apparatus comprises means for transmitting ultrasonic energy into the fluid at each of two spaced positions along the flow, means for receiving the two beams and detecting the modulation thereof due to disturbances in the fluid and a correlator for cross-correlating the two detected noise signals. The waves are transmitted across the flow at two points and the received signals are amplitude modulated by disturbances in the flow (which may be induced by A in laminar flow). The detected AM signals are passed to correlator 15 which determines the delay necessary to produce maximum correlation from which the flow velocity can be determined. Instead of using oscillators 10, 10<SP>1</SP> to supply the energy, the transducers T, R and the amplifier 12 may be connected in a positive feedback loop to provide self-sustaining oscillations at the transducer resonant frequency. In a modification both pairs of transducers are connected in one feedback loop. In order to avoid errors due to phase misalignment between the two pairs of transducers, the detectors may be F.M. demodulators (Fig. 5, not shown). In a further embodiment (Fig. 6, not shown), the phase shift from oscillators 10 or 10<SP>1</SP> to amplifier 12 or 12<SP>1</SP> output is measured at the two stations. The phase comparator (Fig. 7, not shown) comprises gates 30, 32 passing the pulses from the oscillator 10 and amplifier 12 to divide by eight counters 34. The oscillator train is delayed by one quarter period by triggering a sawtooth waveform which is fed to a threshold circuit which in turn triggers a half-period monostable 42. The monostable output and divider 36 output are fed to AND gate 44 which produces a pulse whose width determines the phase difference. This signal is integrated and passed to the signal correlator. A pulse width detector is used to synchronize the dividers immediately after switching on.
