  • Patent number: 4397033
    Abstract: This device comprises two pairs of superimposed pick-up coils 1, 2, 5, 6. Each pair is formed by two windings coupled in series but with opposing winding directions, each winding of one pair having a layer of rectilinear conductive portions 1a, 2a, 5a, 6a side by side parallel to and superimposed on the similar portions of the other winding. These two windings extend on either side of their superimposed layers respectively. The superimposed layers of one pair of windings are orthogonal to those of the other pair.This arrangement is intended to induce in each pair of coils, under the influence of a permanent magnet having a flux approximately perpendicular to these windings, fluxes which add up when the inductive flux varies in a plane parallel to the coils and which are cancelled when the inductive flux varies perpendicularly to this plane.

  • Patent number: 4314444
    Abstract: In a two-stage apparatus for burning a fuel and a combustion-sustaining gas such as air, the first stage (12) comprises pulse combustors (16) supplied with an excess of fuel. The excess fuel is burned in a second combustion stage (14) with gas that is aspirated using the backflow through the aerodynamic valve inlet (20) of the pulse combustor and delivered, e.g. via a duct (40), to the second combustion stage. Heat is extracted from the first stage using a heat-transfer medium (46) such as water. Heat is also extracted from the combustion products of the second stage to produce substantially cooled combustion products, a portion of which recirculates, e.g. through the ducts (54) and (58) and an aerodynamic valve (60), to each pulse combustor. The rest of the cooled combustion products are exhausted, e.g. at (64), with only a low content of objectionable compounds formed from nitrogen in the fuel and the combustion-sustaining gas.

  • Patent number: 4176398
    Abstract: Apparatus receiving step voltage inputs provides an output voltage that moves as a linear ramp from step to step. Each new input causes an amplifying circuit to connect a predetermined potential to an integrator, starting a new ramp. A comparator circuit receives voltages proportional respectively to the input and the ramp output, and when they become equal it stops the ramp. An inverter is automatically connected into the amplifying circuit when needed to change the polarity of the potential to the integrator, and thus to reverse the direction of the ramp. Manual and automatic adjusting and switching means control the operating sequences and parameters.

  • Patent number: 4143275
    Abstract: Method and apparatus for applying radiation by producing X-rays of a selected spectrum and intensity and directing them to a desired location. Radiant energy is directed from a laser onto a target to produce such X-rays at the target, which is so positioned adjacent to the desired location as to emit the X-rays toward the desired location; or such X-rays are produced in a region away from the desired location, and are channeled to the desired location.The radiant energy directing means may be shaped (as with bends; adjustable, if desired) to circumvent any obstruction between the laser and the target. Similarly, the X-ray channeling means may be shaped (as with fixed or adjustable bends) to circumvent any obstruction between the region where the X-rays are produced and the desired location.For producing a radiograph in a living organism the X-rays are provided in a short pulse to avoid any blurring of the radiograph from movement of or in the organism.

  • Patent number: 4124466
    Abstract: Methods of enhancing selected chemical reactions. The population of a selected high vibrational energy state of a reactant molecule is increased substantially above its population at thermal equilibrium by directing onto the molecule a beam of radiant energy from a laser having a combination of frequency and intensity selected to pump the selected energy state, and the reaction is carried out with the temperature, pressure, and concentrations of reactants maintained at a combination of values selected to optimize the reaction in preference to thermal degradation by transforming the absorbed energy into translational motion. The reaction temperature is selected to optimize the reaction.Typically a laser and a frequency doubler emit radiant energy at frequencies of .nu. and 2.nu. into an optical dye within an optical cavity capable of being tuned to a wanted frequency .delta.
