Title: Electrodialysis device
IPC: B01D61/50
Filed: 1960-05-10
Abstract: A multi-compartment electrodialysis apparatus is arranged so that the current density across successive compartments decreases in the direction of flow of the dilute stream 102, i.e., with decreasing concentration of that stream.  This is achieved by making the surface areas of the membranes 20, 21, which with gaskets 51, 52 define the compartments, increase in the direction of flow of the stream 102. Raw liquid 100 entering the apparatus is divided into three streams, 101 (for the electrode compartments), 102 and 103 (the concentrate), and the compartments are arranged in groups A, B, C in series, flow of the streams 102, 103 being in parallel through each group. <PICT:0954022/C3/1> Gaskets 51, 52 decrease in thickness as their bounding membranes increase in area to ensure a constant velocity of liquid flow through the apparatus.  Specifications 682,703, 772,861, U.S.A. Specification 2,708,658, and Australian Specification 164,040 also are referred to.

Title: Measurement of the shape of strip material
Inventor: BOSHER DAVID ROBERT
IPC: G01B11/245
Filed: 1971-08-19
Abstract: 1383320 Measuring shape photo-electrically BRITISH IRON & STEEL RESEARCH ASSOCIATION 18 Aug 1972 [19 Aug 1971] 39069/71 Heading G1A The "shape" of a strip (i.e. the variation across the width of the strip of the distance measured along the surface of the strip parallel to its length between parallel transverse lines) is determined by comparing the displacements of the positions of a plurality of light beams reflected from the strip between two instants of time. Five measuring systems are utilized to monitor separate points across the width of a strip of material passing over a roller. Each system comprises a lens (11) focusing on to the strip an image of a slit (8) extending parallel to the length of the strip and illuminated by a lamp (7). The light reflected from the strip is focused by lenses (13 and 14) on to a linear integrated array (10) of 50 photo-diodes. Vertical movement of the strip causes a related displacement of the point of illumination of the photo-diode array. The array 10 is scanned by means of an oscillator 15 which also operates a gate 17 via a divider 16 to provide an output of single complete scans at spaced intervals of time. The output is stored in a first shift register 18 having a length equal to the number of diodes in the array 10, (i.e. 50). The next output scan is similarly stored in register 18 the previous scan being moved into a second shift register 19. As the third output scan is made the previous two scans are compared bit by bit by means of an exclusive OR gate 20. If the two scans are identical no output is produced but if not the exclusive OR gate 20 produces two pulses spaced by a time proportional to the displacement of the light beam incident on the photo-diode array. This time interval is measured by utilizing the two pulses to open and close a gate 22 and counting the pulses from an oscillator 21 during this interval by means of a diode pump 23 connected to a display 23. The readings corresponding to the five measuring systems may be displayed together to give an indication of the "shape" of the strip and the corresponding signals can be compared to produce a signal to control a rolling mill at the output of which the measuring system is located.

Abstract: 1436877 Colour television INTERNATIONAL VIDEO CORP 14 Aug 1973 [25 Aug 1972] 39510/73 Heading H4F A colour television signal which has been recorded with the chroma signal in a frequency band below that of the frequency-modulated or pulse-interval-modulated luminance signal is played back, the luminance and chroma signals are separated by filters 44, 63, and the luminance signal is demodulated 46, the horizontal sync signal separated from the output of demodulator 46 being used in a phase locked loop 52 to produce a signal which is fed to a mixer 56, from the output of which is produced a chroma signal on a subcarrier whose frequency is the same as that of the chroma signal prior to recording, this signal being added at 62 to the luminance signal. A squaring circuit 90 produces a signal at twice the frequency of the recorded subcarrier to cancel unwanted second order chroma sidebands. In the embodiment of Fig. 4 the chroma signal from 56 has the same long term time base errors as the luminance signal and these long term time base errors in the composite output of adder 62 are removed at 60 using two phase comparators and associated voltage controlled delay lines, one phase comparator (64, Fig. 5, not shown) comparing the phases of the output of circuit 58 of phase locked loop 52 and a reference horizontal reference signal, and the second phase comparator (70) comparing the phases of the colour bursts separated from the output of adder 62 and reference colour bursts. In a second embodiment (Fig. 6, not shown) circuit 60 is omitted and the chroma input to adder 62 is free from time base errors. This input is produced from a mixer (82) receiving inputs from low pass filter 63 and a further mixer (78) providing a signal at the sum frequency of the outputs of a stable oscillator (80) and the voltage controlled oscillator (74) in the phase locked loop. The colour television signals may be PAL, NTSC, or S.E.C.A.M. signals.

Title: Headbox for and method of delivering a fibre slurry
IPC: D21F1/02
Filed: 1973-08-24
Abstract: 1423874 Headbox CROWN ZELLERBACH CORP 24 Aug 1973 [12 Oct 1972] 40245/73 Heading D2A [Also in Division Fl] In a method of and headbox for delivering a fibrous slurry to the surface of a forming wire, use is made of the "Coanda effect", i.e. the tendency of a fluid emerging from a slit under pressure to follow an extended lip of the slit which diverges from the flow axis of the fluid. The headbox incorporates an elongate exit aperture and an elongate slit communicating with the flow path of the slurry, the aperture and slit extending substantially parallel. In one embodiment, Figure 1, white or clear water forced along path 74 to emerge at slit 84 follows surface 82 so as to drag slurry in channel 100 to exit A. The ratio of the velocity of the fluid emitted from slit 84 to that of the slurry upstream of the slit 84 is preferably at least 10, this ratio causing total mixing of the fluids and the breaking up any flocs in the slurry. Pivoted members 92, 94 may be adjusted by rams 96a, 96b so as to vary the velocity, degree of turbulence &c of the fluid mixture emitted. Similarly, the configuration of flow path 74 may be adjusted by rams 70. The slurry is delivered to the throat B under a head generated in the headbox, and preferably follows a path prior to throat B which minimises any turbulence. Pivotable baffles 23, (36) (Figure 1, not shown) which may define the flow path, enable the path to be altered within limits. In a further embodiment (Figure 5) the Coanda effect is made use of at surfaces 130, 132 and at the outlet nozzle. Water under pressure enters via conduit 124 to initiate slurry motion, e.g. synthetic fibrous slurry, toward the outlet. Conduifs 118 allow a second fluid under pressure, e.g. a conventional wood pulp, water or a chemical, to generate a further dragging force which moreover also mixes the constituents. Adjacent the variable jaw members 142, 143, a third fluid, e.g. water, enters via conduits 138 at a velocity which brings the slurry velocity up to the value required. A reinforcing scrim of nylon or other material 146 may also be ejected through jaws 142, 143 under the fluid pressure. Other embodiments describe oppositely placed Coanda effect slits which effect slurry motion in adjacent separate channels thereby enabling manufacture of, for example, liner board, since different fibrous slurries may be employed simultaneously. Further, the defining walls of the Coanda slits may be incorporated in a body which may rotate relative to the throat so as to allow the fluid flow parameters to be varied. In the above embodiments the slurry mixture is discharged horizontally onto a horizontal web. In yet a further embodiment, however, (Figure 10, not shown) the slits &c are arranged to discharge the slurry vertically onto a vertical web.
