Filed: 1925-05-22
Abstract: 234,515. Krumm, P., and Seignol, E. May 23, 1924, [Convention date]. Indicators actuated by pressure of head of liquid.-The level of a liquid in a vessel, such as the fuel tank of a motor vehicle or aeroplane is indicated upon a gauge the reading of which depends on the pressure head of the liquid upon a pressure transmitting and 'multiplying device which communicates with the gauge. The effect of the pressure head of the liquid upon the flexible underside of a manometric chamber 11, Fig. 1, is communicated to a valve 7 which closes an aperture in a chamber 8 in communication with the gauge 1 and an air compressor 4. When the liquid level in the tank falls, air escapes from the chamber 8 and the reading of the gauge falls. In a modification, the movement of the valve is controlled by a vacuum. In another modification, the pressure head of the liquid ,acts upon a bellows 12, Fig. 3, enclosing a smaller bellows 13 containing a liquid, such as glycerine, the movement of which varies the reading on the gauge.

Abstract: 481,065. Turbines. FOURCADE, H. May 14, 1937, No. 13641. Convention date, May 15, 1936. [Class 110 (iii)] The turbine comprises rotors 4, 18, secured to shafts 5, 23, which rotate in opposite directions. Motive fluid is supplied through the shaft 5 to the interior of the rotor 4, and is ejected through nozzles 16 on to blades 19, causing the rotor 18 to be driven forwards and the rotor 4, backwards. Power is taken off the shafts by means of pulleys 17, 24. To exert a braking effort on either shaft, either pulley may be stopped by the engagement of a conical clutch 40. The working fluid which may be water, steam, or gas, is exhausted through a pipe 25. Fig. 4 shows a plant in which steam, supplied through a pipe 28, through an injector draws up water through a pipe 29. Air may also be admitted to the mixing chamber 27 by way of a pipe 32. The water exhausted from the turbine 1 is returned to the supply tank 31, which may also supply the steam generator. The speed of the turbine is regulated by controlling the mixture of fluids supplied through the shaft 5. The convergent - divergent nozzles 16 may be replaced by orifices with bevel edges.

Secret signalling systems; distortion of voice currents, effecting and neutralizing; filter circuits.-In order to render broadcast wirless tele,- phony unintelligible or unpleasant to any but authorized receivers, the carrier wave is modulated by interfering or confusing tones or signals as well as by the desired signal, the authorized receivers are fitted with devices, preferably filter circuits, which eliminate the interfering tones. High or low tones outside the range of normal speech or music may be chosen for the interfering tones; or tones between two of the frequencies used in the tonic scale. Combinations of tones producing discord or beats may also be used. The filtering circuits, for eliminating the interfering tones at the receiver, comprise known combinations of inductance and capacity, and are connected in the low-frequency circuit. The interfering tones may be changed from time to time, necessitating a corresponding change in the filter circuits. The coils of the filter circuits mav be set in cement so that they cannot readily be duplicated by unauthorized persons. The interfering tones may be sent continuously, or at intervals. The Specification as open to inspection under Sect. 91 (3) (a) refers also to signalling other than telephony. This subject-matter does not appear in the Specification as accepted.
