Title: Improvements in or relating to electrical signalling systems
IPC: H03C1/34
Filed: 1935-07-16
Abstract: 460,187. Valve modulating. circuits. AUTOMATIC ELECTRIC CO., Ltd., and TERRONI, T. B. D. July 16, 1935, No. 20300. [Class 40 (v)] [Also in Group XXXVI] In a signalling system in which the characteristic of the signals is dependant upon an alternating current impulse ratio, i.e. the proportion of a cycle open to the proportion closed as when meter readings are transmitted by scanning, two thermionic valve systems are used, one to generate oscillations of constant frequency which are applied to an electrode of the second system. The conductivity of the second system is varied abruptly in dependence on the signal. Fig. 1 shows an arrangement in which a photo-cell 32 controls the conductivity of the pentode section of a triode-pentode, alternatively a controlled triode in series with an oscillator anode supply may be employed, Fig. 2 (not shown), while the photo-cell output may be amplified and applied to one grid of a tetrode operating as a triode oscillator, Fig. 3 (not shown), the coupling of the amplifier to the oscillator may be by a neon tube or gas discharge device. Fig. 6 shows an arrangement in which a three electrode neon tube 83 is used coupled by a transformer 81, 82 so that the variation in potential initiates oscillations or causes oscillations to cease, while the output is taken from the grid of the generating valve V2. When applied to sub-station control from a central station if the line is continuous a direct current relay may be provided to connect up one or two receiver transmitters so that subsequent signals shall operate the receivers independently and cause these to transmit to the central station. A two-position relay system is described, Fig. 7 (not shown), and a three-position polarized relay may be employed. The invention is also applicable to power protection systems to indicate line leakage or operate protective gear by using a watt meter of the photo-telemeter type to transmit between the ends of the line and arranging that rectified signals, representing the power at the two ends of the line, are applied differentially to a moving coil instrument to indicate leakage or to close a contact to trip protective gear. Specification 441,881, [Group XXXVIII], is referred to.

Title: Improvements in or relating to apparatus for pneumatically operating or controlling musical instruments
IPC: G10F5/02
Filed: 1932-07-19
Abstract: 388,655. Automatic musical instruments. HANDS, F. C., 80, Selhurst Street, Hyson Green, Nottingham. July,19, ] 932, No. 20414. [Class 88 (i).] An automatic musical instrument with means for playing from different tunesheets successively, comprises two tracker boxes 3, 3a with valve mechanism 6, 22 wherein the valves are shown in the position for playing tune-sheet 2 while tune-sheet 1 is being re-rolled. The two sets of tracker ducts 5, 5a are connected to the same set of valves 11 through chambers 8, 8a, pressure air in chamber 8 causing membranes 9 to obstruct the ducts 5, and suction air in chamber 8a withdrawing membranes 9a so that air entering a note-hole in sheet 2 depresses valve 11 allowing suction from chamber 13 to collapse pneumatic 17, closing valve 18 and permitting pressure air from chamber 15 to pass to the note action 19. On completion of the playing of a sheet, pressure and suction in the chambers 8, 8a are automatically reversed to couple the other tracker bar to the action, as follows. An aperture at the end of sheet 2 uncovering a pipe 31 moves a valve 36 to the right, allowing suction from chamber 25 to pass by duct 30, chambers 29, 24, duct 40, and chambers 37, 38 to bellows 39a. Bellows 39a collapses and moves pivoted valve 42 to open duct 43 causing diaphragm 45 to move valves 27, 28 to the right, chamber 8 being shut off from the pressure air in chamber 26 and connected to suction now reaching chamber 21 from chamber 25, while chamber 8a is now connected to the pressure air in chamber 26 and cut off from the suction in chamber 29. Simultaneously, the drives of the tune-sheets are reversed, the suction now in chamber 8 collapsing a bellows 58, and the pressure in chamber 8a distending bellows 58a, in each case operating a clutch lever 57. Bellows 58, in collapsing, also applies brake shoes 68 to the flanges of the feed-roll 47 as the drive is transferred to the take-up roll 48 for playing. Braking of the roll 48 during rewinding is sufficiently supplied by a spring at the end of its axis. A pawl 69 prevents overrunning of the roll 48 at the end of rewinding, slipping off the tune-sheet into a notch in the roll. Specifications 339,771, [Class 88 (i), Musical instruments, Automatic], and 379,965 are referred to.

Filed: 1959-06-16
Abstract: 886,972. Ultrasonic inspection of materials. KRAUTKRAMER, J., and KRAUTKRAMER, H., [trading as KRAUTKRAMER GESELLSCHAFT FUR ELEKTROPHYSIK, J. & H.]. June 16, 1959 [June 16, 1958], No. 20622/59. Drawings to Specification. Class 40(7). In a method of pulse-echo ultrasonic testing the probe and test piece are moved continuously relative to one another and within an adjustable range of echo times only echoes varying in amplitude and/or traverse time are filtered out and used to give indications or effect switching. False operation arising from boundary echoes is thus obviated when flaws near to the boundaries are to be detected. Variations in the traverse times or amplitudes of the boundary echoes may be compensated by using three range gates, the first of which covers the front surface of the test piece, the second the rear surface and the third the whole test piece thickness; echoes in the first two gates are brought into a coincidence circuit such that simultaneous and like changes in both gate periods compensate for the simultaneous change in the third gate period. The apparatus described comprises a known testing unit with the addition of either a differentiating stage, the Figure (not shown), the time constant of which is adustable so as to block signals having slow amplitude changes, or a bandpass filter having adjustable upper and lower cut-off frequencies. The invention may be applied to the testing of turbine blades. It is stated that test piece thickness variation may be measured by indicating the concomitant echo time variations.
