  • Patent number: 4126382
    Abstract: An operational method is disclosed for the display of images by an electro-optical device comprising a liquid-crystal cell inserted between two polarizing devices, means being provided for impressing on the liquid crystal electric pulses, the improved method comprising the step of applying a pulsed energization, each pulse being any voltage waveform having a duration and an RMS amplitude such as to originate, at each pulse, a cell luminous response and not exceeding 1.3 times those which are required to produce a flash of light with a peak amplitude which cannot be further increased without causing more than one peak to appear. In the case of repetitive energization, the pulse repetition period, under steady conditions, shall be such that at the end of the period, the luminous response of the cell falls irreversibly to a value which is not more than one half of that peak value corresponding to "white level".

  • Patent number: 4110710
    Abstract: A microwave band branching arrangement for successively coupling frequency sub-bands of a broad frequency band of energy has a coupler for coupling the highest sub-band of frequencies at one end of the arrangement and a series of successive couplers which are each arranged to sequentially couple frequency sub-bands of energy in an ascending order of frequency from the coupler which couples the highest frequency sub-band. By arranging that the highest frequency sub-band is coupled first, it is subjected to a lower attenuation. In further embodiments of the invention, where the arrangement is used, for example, in a repeater station, sub-bands of energy are coupled out, regenerated and amplified, and reinserted by a further coupler into the arrangement for further transmission.

  • Patent number: 4095159
    Abstract: This invention relates to an electronic apparatus for automatic positioning and distance measurement of mobile members. The apparatus according to the invention comprises a rotary electromagnetic transducer with two pairs of windings, in which the primary circuits receive electrical voltages representative of the controlled angular distance values and the secondary circuits deliver accordingly an electrical response voltage, whose shape and amplitude depend on the difference between said controlled distance and the mechanical angle between rotar and stator portions containing said secondary and, respectively, primary circuits. The electrical voltages representative of the controlled angular distance values are generated by electronic circuits comprising a first binary counter which translates the controlled distance into binary code, a second binary counter which generates a binary ramp, two adders, a combining network, four sequential networks and two analogue amplification and sign circuits.

  • Patent number: 4091833
    Abstract: A first inductive coil in the form of a bifilar winding is wound on a ferrite ring core with the two sections of the bifilar winding connected in series, the junction of the two sections forming the center tap of the coil. A capacitor is connected across the first coil to form a parallel resonant circuit therewith. The two ends of the first coil are respectively connected to a predetermined capacitance and to an electrode adapted to form a capacitative element whose dielectric includes a fluid under test. The center tap of the first coil is connected to the output of an amplifier whose input is connected to a second, detector coil comprising a separate winding on the ferrite ring core located substantially at the mid-point between the ends of the bifilar winding. The second coil is arranged to be inductively coupled to said first coil such that the mutual inductance between the first coil and the detector coil completes a feedback loop for the amplifier.
