Title: Improvements in or relating to Apparatuses for Digital Measurement of Distances by Means of Ultrasonic Pulses
IPC: C09B1/54
Filed: 1967-02-07
Abstract: In a system providing a digital measurement of the separation of two points in a medium by counting clock pulses in the interval between transmission of an ultrasonic pulse from the first point and reception of the echo obtained by reflection of this pulse at the second point, the measurement is made independent of variations in the ultrasonic wave propagation velocity by making the clock pulse frequency the frequency defined by an acoustical resonance phenomenon in a space of predetermined length within the medium. In the embodiment of Fig. 2, clock pulses from generator 16 are passed to counter 15 for a time determined by receivercontrolled gate 14 and the separation of transmitting/receiving transducer 11 from a reflecting surface S is indicated directly on unit 17. A transducer pair A 0 separated by a sample of the medium or in the medium itself provides an acoustic feedback path for an amplifier in generator 16 to define the clock pulse frequency. If the wave propagation velocity varies with distance along the propagation path between transducer 11 and the surface, transducer pair A 0 and further pairs A 1 , A 2 . . . are sequentially connected to the amplifier during the pulse propagation interval to give a sequence of different clock pulse frequencies related to the different propagation velocities in respective successive portions of the said propagation path. Auxiliary receiving transducers T 1 , T 2 . . . disposed at different distances from transducer 11 detect the ultrasonic pulse propagating between transducer 11 and the surface and provide timedisplaced trigger signals which actuate commutating circuits C 0 , C 1 , C 2 . . . to effect the sequential connection of the transducer pairs A 0 , A 1 , A 2 . . . to the amplifier.

Title: Sensor testing device
IPC: G01M99/00
Filed: 1968-12-24
Abstract: Apparatus for testing the working of a flame detector such as an ultra-violet sensitive tube in a burner control system includes means for simulating a no-flame condition, such as an electromagnetically operated shutter to shield the tube from radiation, and a check circuit to sample the output of the detector after a predetermined interval provided by a timer such as a unijunction timer 38 and provide a signal, commensurate with that output, to which indicating means is responsive, the shutter being opened again after a predetermined period. The apparatus includes a rotary switch 10 operated by a timing mechanism such as a clock and output pulses therefrom are applied to an OR gate 12 and to a pair of AND gates 14, 22, 16, 24, 18, 26 or 20, 28. The OR gate 12 applies a signal to a pulse generator 30 which may be a monostable multivibrator and its output pulse is applied to the set input terminals of bi-stable multivibrator 32, 34 which results in output signals from bi-stable 32 to disable a timing circuit 36 and energize a timing circuit 38. Circuit 36 comprises a free running oscillator which, except when it is disabled by a signal of the proper polarity at the set output terminal of bi-stable 32 will provide a series of pulses to the reset input of bi-stable 34 so that generation of a pulse by generator 30 will switch bi-stable 34 this multivibrator not being reset until after timing circuit 36 has been released by the resetting of bi-stable 32. The reset output terminal of bi-stable 34 is connected to the input of selector AND gates 22, 24, 26, 28 so that the gate provided with a signal by switch 10 will be opened to provide a signal to one of checking circuits 40, 42, 44, 46 and the bi-stable is also connected to a primary driver 48, which may be an amplifier, the output of which is applied to shutter AND gates 50, 52, 54, 56. Accordingly an output signal at one of the master switch output terminals causes closing of a shutter in front of the selected device, the current for energization of the shutter being supplied by amplifier 48. Malfunction is indicated by an alarm.
