Title: Ultrasound echometer
Inventor: BESESTY PASCAL
IPC: G01S15/10
Filed: 1986-10-01
Abstract: The invention relates to an ultrasound echometer. This echometer comprises a generator 1 supplying a sequence of oscillations applied to an ultrasonic transducer 3. A sample 5 receives the corresponding sequence of ultrasonic oscillations, and a receiver 6 receives the echo of the ultrasonic oscillations in the sample. The device comprises means 7 for measuring the time elapsed between the emission and reception of the ultrasonic oscillations. These measurement means comprise an adjustable phase-shifter with measurable delay 9, which receives the emission oscillations, and which phase-shifts them in order to make them coincide with the echo oscillations. Processing means 13 allow this coincidence to be detected, and means 16 for measurement using this coincidence makes it possible to make a more precise measurement of the phase shift measured by the phase-shifter 9 at the coincidence. Application to ultrasound echometry.

Title: Atmospheric air engine
IPC: F01D15/00
Filed: 1987-05-29
Abstract: Appliance creating energy capable of actuating all fixed or movable land or marine engines using solely atmospheric air for an energy supply. The invention relates to the assembly of components used or not used in industry, for constructing a movement which, in a first instance, operates in an almost autonomous closed circuit by means of compressed air. The inevitable loss in energy is therefore compensated by auxiliary compressors, powered conventionally. This complex has the effect, in a second phase, of actuating a supercompressor which sucks in atmospheric air and, according to the principle of the compressed-air rifle, sets in motion the pistons of an engine of a current model. The coefficient of power of injection with respect to sucked-in air, which is enormous, makes it possible to substitute the explosion of hydrocarbon or other energy-yielding product in a cylinder of conventional design.

Title: Thermal insulating felt and process for its manufacture
Inventor: DRI JEAN-PIERRE
IPC: D04H1/46
Filed: 1987-12-01
Abstract: The production of a felt made up of a number of layers and having a high thermal insulating power. A relatively thick intermediate layer is placed on a first sheet of felt 1, followed by a second sheet of felt 2. The sandwich thus formed is assembled by needling or stitching through the intermediate layer and then this intermediate layer is removed by chemical digestion, dissolving or melting. A central region 3 is thus obtained which forms a sheet of air and through which pass fibres 4 or threads forming connecting points between the two outer sheets 1, 2. A reflective film 5 can be provided on the inner face of one of the sheets 1, 2 and is thus protected from soiling, especially by smoke. Such felts can be employed especially for producing garments or screens for heat protection.
