IPC: H01P1/22
Filed: 1969-10-23
Abstract: 1289337 Waveguide dissipative loads TAVKOZLESI KUTATO INTEZET 23 Oct 1969 [23 Oct 1968] 52029/69 Heading H1W A variable microwave attenuator in a rectangular waveguide includes a powdered iron member 5 and a spaced dielectric member 6, both mounted parallel to the narrow sides of the waveguide, and movable in a direction perpendicular thereto by the actuating rod 3. In the position shown, the lossy member 5 is in the position of maximum field strength, and produces maximum loss. When rod 3 is withdrawn, to bring member 5 into the region of low field strength against the waveguide wall, its loss is additionally reduced by the condensing effect of the dielectric member 6. Both members are of reduced cross-sectional area towards their ends in the direction of the longitudinal axis of the waveguide (Fig. 6, not shown), to reduce reflection, their otpimum size and mutual spacing being determined by trial and error, but the spacing preferably falls within 10 to 50% of the width of the waveguide. In a further embodiment (Fig. 5, not shown) members 5 and 6 are independently movable, by an arrangement of one rod sliding within another.

Abstract: 1296974 Automatic control SMITHS INDUSTRIES Ltd 12 Dec 1969 [17 Sept 1968] 44071/68 Heading G3R In a control system provided with at least three channels for redundancy, excessive deviation of a signal in one channel relative to the signals in the other channels renders that channel ineffective and lesser differences, detected by separately comparing the signal in each channel with the signal in each of the other channels, are eliminated by applying the differences associated with each channel through a limiter to correct the signal in that channel. Fig. 2 shows one of three identical channels of an aircraft automatic pilot controlling common elevators or ailerons 38 from instruments 23 so as to obtain a desired pitch or roll attitude or to effect radio navigation, altitude control or automatic landing. Control signals derived from a computer 22 associated with the instruments are applied through an amplifier 28 to an AC servomotor 29 which, by virtue of feedback from a tachometer generator 31 adjusts control surfaces 38 at a rate dependent on the resultant of the other signals applied to amplifier 28. Signals from a gyro 25 responsive to rate of turn of the aircraft about the axis of control, and signals from computer 22, integrated at 50, are also applied to the imput of amplifier 28. If the torque of servomotor 29 is in such conflict with that of the servomotors in the other channels that a switch 41 is opened, a clutch 34 is de-energized to render the channel ineffective. This also happens if a unit 43, which applies test signals to amplifier 28, does not detect a corresponding amplifier output signal and opens contacts 42, or if servomotor 29 is not energized and a relay 32, associated with it, opens contacts 33. Units 45 and 46 separately compare the output of amplifier 28 with the outputs of corresponding amplifiers in the other channels and limited signals corresponding to any differences are combined at 49 and applied to the input of amplifier 28 in a sense tending to eliminate the differences. Integral components of the differences are also added by integrator 50 and the gain of the channel is also adjusted in dependence on the magnitude of the differences by applying the differences to units 51 and 24 which respectively vary the signal output of tachometer generator 31 and rate of turn gyro 25. Alternatively, unit 24 may adjust the output of computer 22 and/or unit 51 may adjust the feedback from tachometer generator 31 or the other inputs to amplifier 28.

Title: Methods and apparatus for faulty-product detection in manufac turing equipment
IPC: G07C3/14
Filed: 1969-05-02
Abstract: 1316421 Packing machines FINDLAY IRVINE Ltd 20 May 1970 [2 May 1969] 22607/69 Heading B8C [Also in Divisions G4 and H3] In a manufacturing machine producing a series of articles 10, faulty ones are separated by apparatus including a shift register 24, a shift pulse generator 43 producing pulses synchronized with the movement of the machine and control means coupling each of a number of fault detectors 12 to a corresponding one of the shift register stages only during a corresponding instant of the cycle, the end stage of the shift register being coupled to a rejecting mechanism to reject a faulty article at the rejecting station as a result of the entry of a fault signal from any of the fault detectors 12. As the articles 10 move through the machine nine fault detectors 12, responding is nine different faults, examine each in turn and upon detection of a fault, a signal is passed through a noise filtering gate 13 to gate 15. This gate is opened during each machine cycle for a period determined by tuning pulse generator 32. A shaft 30 rotating as the machine operates generates in unit 31 a series of ramp voltages on line 35. Each generator 32 has two adjustable voltage sources 33, 34 which are applied to comparators 36, 37 also receiving the ramp. The outputs of the comparators set and reset flip-flop 40 to produce the timing pulse. If the signal 51, Fig. 2, from detector 12 coincides with the timing pulse 54 gate 15 produces an output 56 which sets flip-flop 19 giving an output 58 on line 21. This is differentiated at 22 to obtain a pulse 60 which is used to set the stage 1<SP>1</SP> of register 24. The other detectors are gated with suitable timing signals produced in the same way by generators similar to generator 32. Another generator of similar design produces a timing signal to be gated at 15<SP>1</SP> with the output of the last stage. The output of this gate sets flip-flop 19<SP>1</SP>. The output is differentiated at 22<SP>1</SP> and controls a rejecting mechanism. The detectors 12 may be photo-electric sensors detecting missing print on the package, departures from the correct shape, colour or transparencies or missing components. Additionally the weight may be measured by a suitable transducer and means may be provided to detect discontinuities in wrapping paper or the like.

Title: Method for the processing of the images of a batch of images
Inventor: BERRAH HAFIDA
IPC: G01T1/164
Filed: 1993-12-21
Abstract: The noise in the images is eliminated by carrying out a first Fourier transform (11) of the images of a set of original images (I). Each of these transformed images (R, J) is next decomposed into a Fourier series (A, PHI, B, PSI) in order to disclose the principal harmonics (M) of a periodic evolution of the original images and transformed images. On the basis of this harmonic decomposition, transformed images (RH, JH) are recomposed (14, 15) and are thus filtered through rejection of the unuseful harmonics. An inverse Fourier transform (16) is carried out on the basis of the filtered transformed images so as finally to obtain filtered original images (F). It is shown that in this case the filtering removes the noise without impairing the structures of the image, and without distributing the noise over all of these structures.
