Title: Zero-crossing comparator with threshold validation
IPC: H03K5/153
Filed: 1980-09-04
Granted: 1984-06-20
Abstract: In carrier and timing recovery systems for high performance data modems it is essential to employ threshold comparators and to be able to determine accurately zero-crossing instants.

Title: Filtering electrical signals
Inventor: CRAMPTON EDWARD CHRISTOPHER TH
IPC: H04B3/56
Filed: 1983-11-07
Granted: 1988-03-16
Abstract: A ferrite loop 21 encircles the line 11 and neutral 12, but not the earth cable 13 of a mains supply. The loop 21 also encircles a further loop 22 which comprises a capacitor 23. The further loop 22 including its capacitor 23 forms a parallel LC circuit which provides a high impedance to signals at the resonant frequency of the LC circuit in a circuit including the neutral and earth cables. The filter has substantially no effect on signals at mains frequency, since the loop 21 encircles both the line cable 11 and the neutral cable 12. There is also disclosed a filtering system comprising two such filters arranged along the arm of a T-filter system, the stem of the T comprising a series LC circuit to provide a low impedance path for signals at its resonant frequency.

Title: An electro-optical detection system
Inventor: SUTTON PHILIP
IPC: G01S7/487
Filed: 1989-05-11
Granted: 1998-06-24
Abstract: An electro-optical detection system for detecting objects embedded in a partially transmitting medium. The system includes a receiver for receiving electromagnetic radiation and a device for separating the received radiation into two separate spectral channels. A detector in each of the spectral channels for providing a signal indicative of the received radiation in each spectral channel. A signal processor, responsive to the outputs of the detectors, having a signal channel where transmission of light of the signal channel wavelength in the medium is high and having a reference channel where attenuation of light of the reference channel wavelength in the medium is high. The signal processor ensures that the reflected light at both signal and reference wavelengths are of similar intensity and geometric distribution. A subtractor provides a difference output in which the signal and reference channels are subtracted, removing the effect of reflected light.

Title: Lip seal for the sealing of a shaft,in particular a ship's propeller shaft
Inventor: VON BERGEN ERNST-PETER
IPC: F16J15/322
Filed: 1992-12-16
Granted: 1995-01-25
Abstract: This invention relates to lip seals for shafts, whose lip bodies consist of rubber elastic material, and is mounted on the reverse side on an essentially radial surface of a back-up ring which is integral with the housing. When the pressure of the medium to be sealed out increases, dangerous overloads occur on the lip edge, in spite of the roller diaphragm-like deformation of the lip body. According to the invention, these overloads are reduced by the introduction of a trough in the supporting back-up ring in the zone of the lip body near the clamp, into which the lip body is deformed and thus the pressure on the edge of the lip is reduced (FIG. 1 ).

Abstract: In a telecine chain, the scanning raster is rotated by applying a magnetic field perpendicular to the axis of the electron beam, and the distortion introduced by such rotation is compensated for. A rotate coil is located about the scanning tube the coil formed so that current passing through it induces the magnetic field and thus effects the rotation of the raster. The degree of rotation is within limits dependent on the current, and the direction of rotation is dependent on the direction of current flow. There is pref. an Absolute Angle Generator which has an input common with the input which controls the current through the Rotate Coil and which provides outputs for the compensation functions. Focus compensation is effected by applying a stimulus to the focus system which is based on the degree of rotation being effected.
