Title: Transversal filters
IPC: H04L25/03
Filed: 1979-06-21
Abstract: An adaptive transversal filter for use in rejecting interference comprises: a tapped delay line having a central tap point (1) and further tap points (2A, 2R; 3A, 3R; 4A, 4R; 5A, 5R) in pairs symmetrically disposed with respect to the central tap point; means (10-13, 14) for weighting and then summing the signals from the further tap points, the two signals from each pair of points being equally weighted; means (16) for subtracting the weighted sum from the signal received from the central tap point; and control means (17-20) for estimating the correlation between the output signal from the subtraction means and the input signal and deriving from these correlations weighting coefficients for the weighted sum. Because the weighting coefficients are applied in a symmetrical way relative to the central tap point of the delay line, no phase distortion is introduced by the filter. The filter may be used to remove noise from a comparatively well correlated and stable signal, or to remove highly correlated interference from a relatively uncorrelated signal, eg a speech signal. <IMAGE>

Patent GB-2044941-A (GB)
Title: Apparatus and method for simulation testing of anti-skid system
IPC: G01R31/00
Filed: 1980-02-19
Abstract: In operation the multiplexer (82) first feeds a fixed frequency signal (86) to all inputs of the processor-controller (14) under test and then selects one input at which the fixed frequency signal is maintained and connects the remaining inputs to a variable frequency source (96, 98, 88). The processor (84) then causes the second source to decrease its frequency thereby forcing the processor-controller (14) to adopt the fixed frequency as the reference frequency. Thereafter with the fixed frequency still adopted in the processor- controller as the reference frequency the selected input is coupled by the multiplexer (82) to the second frequency source and in a first period the frequency of the second source at the selected input is lowered so as to cause a pressure release signal to be generated on the corresponding output of the processor-controller (14) and in a second subsequent period the frequency at the selected input is increased towards the frequency of the fixed frequency signal so as to cause a pressure hold signal to be generated at the said output. These output signals are measured. <IMAGE>

Patent GB-2052753-A (GB)
Title: NMR systems
IPC: G01R33/54
Filed: 1980-04-18
Abstract: In a NMR pulse sequence dispersion caused by inhomogeneity in the steady axial magnetic field may be reduced by applying a 180 DEG 'spin- echo' RF pulse (C-C<1>). However, whereas it is possible in known pulse sequences to apply a 90 DEG  RF pulse (e.g. A-B) in the presence of a selected gradient (Gz) and to phase correct it adequately, this is not true for the 180 DEG  pulse needed in a simple echo system (or the multiple pulses of more complex systems). It is proposed instead to apply the 180 DEG  H1 pulse (C-C<1>) in the absence of an axial field gradient. For this purpose it is desirable to apply the RF field and sense the resonance with different coils. The RF coils should be of substantially greater extent in the axial direction than the resonance sensing coils. <IMAGE>

Patent GB-2051545-A (GB)
Title: Removing surface fibres from animals
IPC: B26B19/24
Filed: 1980-05-09
Abstract: In a method of removing surface fibres, e.g. wool, from animals or skins provision is made for freeing the fibres from the fibre-engaging means to facilitate collection of the fibres. A bar having teeth 5 is moved in an arcuate path from a starting position generally transverse to the length of the fibres whereby it moves generally longitudinally of the fibres until fibre fracture is achieved, whereupon the direction of movement is reversed to free the fibres. Alternatively the fibre-engaging means comprises toothed bars pivotally mounted within a rotating drum and projecting through slots in the drum to engage the fibres and withdrawing within the drum to release the fibres. <IMAGE>
Patent GB-2078955-A (GB)
Title: Improvements in detecting an interface between two media
IPC: G01F23/296
Filed: 1980-06-26
Abstract: A tuning fork is disposed with one prong 3 arranged horizontally within a vessel containing a medium, such as a foam, and the other prong 4 outside the vessel. Excitement of the prong outside the vessel causes sympathetic excitement of the prong within the vessel. If the vibration of the outer prong is stopped suddenly the vibration of the inner prong dies away with a decrement which depends on whether the inner prong is immersed in the medium or is above the surface of the medium. It is therefore possible to determine when the level of the medium within the vessel rises or falls above or below the inner prong. By utilising two tuning forks it is possible to determined upper and lower level limits for the medium within the vessel. <IMAGE>
