Title: Process for obtaining a more concentrated solution of a compo nent using ion exchange beds
IPC: C02F1/42
Filed: 1973-04-25
Abstract: 1433338 Ion-exchange; chromic acid ECOTEC Ltd 25 April 1973 [2 May 1972] 19526/73 Heading C1A In a process for concentrating a solution of a component A by (1) absorbing A from a relatively dilute first solution on to a first ion-exchange bed, (2) removing A from the bed by passing through it a relatively concentrated second solution containing B exchangeable with with A and also containing C of opposite charge to A, (3) passing the second solution (now containing A and C) through a second ionexchange bed capable of retaining C and (4) then rinsing both beds, the improvement comprising (a) passing the second solution directly from the first to second bed (i.e. without an intervening reservoir) and (b) passing the rinse solution through the second bed directly to the first bed in a direction countercurrent to the flow of second solution. The solution to be concentrated may be chromic acid or a nickel salt solution, formed as spent liquor in plating processes and to be recycled to the plating path, component A being chromiumcontaining anions or nickel cations. In one such process for recovering and concentrating chromic acid (Fig. 1), the dilute chromic acid solution, obtained by passing rinse water through cation exchanger 5, is fed to the concentrator 6 (Fig. 2). Chromium-containing anions are absorbed by passing the solution downwardly via valve 26 through anion exchanger 20, pure water being recycled at 11. Aqueous NaOH (the second solution) is then passed upwardly through the bed and thence via line 22. The sodium chromate solution issuing from the top of 20 is then passed directly via line 22 and valve 24 upwardly through H+-form cationic exchanger 21 where Na<SP>+</SP> exchanges with H<SP>+</SP> to form concentrated chromic acid for recycle to plating bath 3. Both 20 and 21 are then rinsed by passing water from 19 downwardly through 21 and then 20 and thence via line 15 to NaOH reservoir. Dilute chromic acid, solution (diverted from line 9) may also be used as rinse liquid. In order to avoid undue dilution of the NaOH, valve 25 may be adjusted to divert the rinse to waste. On completion of rinsing, the first step of the process is repeated by feeding further dilute chromic acid to anion exchanger 20, via cation bed 9, and at the same time, cationic exchanger 21 is regenerated to H<SP>+</SP>-form by passing in H 2 SO 4 . NaOH solution is then passed through both beds as before. In example chromic acid containing 44À2-78À9 g./l. CrO 3  litre is obtained from rinse water containing 0À316-7À74 g./l. CrO 3 .

Title: Telephone subscribers metering arrangement
IPC: H04M15/00
Filed: 1972-04-27
Abstract: 1348604 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 27 April 1972 [29 April 1971 (3)] 19625/72 Heading H4K In a telephone metering arrangement, each subscriber's line is provided with a respective electronic (i.e. static electrical) gate that is scanned at a rate high enough not to miss any metering pulse by a scanner that is duplicated in its entirety. The arrangement is applicable to exchanges using rotary or cross-bar switches. As shown, a group of 16 subscribers' gates are connected between a common duplicated enabling amplifier AMP1, AMP2 and respective duplicated transistor discriminating amplifiers. The latter are effective to discriminate genuine metering pulses from impulsive interference having voltages up to 50 v., durations of 15 m.sec. and frequencies up to 6 Hz. The outputs B of each amplifier pair are individually connected to a data processor which distinguishes the members of a group by virtue of the individual connections and also ensures that all metering pulses are registered once and only once. The gates, which are not duplicated, each consist of a resistor chain R1, R2 and R3 connected between a subscriber's C wire and a reference potential e.g. earth. Resistors R1 and capacitors C1 form a filter for giving additional protection against impulsive noise. An output from each gate is taken from the junction of resistors R2, R3 via a diode D1 to the discrimination amplifiers. An input to each gate extends over capacitor C2 from the scanning amplifiers AMP such that if a metering pulse is present when a scanning pulse appears the potential change at the junction of R2, R3 is effective on the discrimination amplifier. The group scanning amplifiers are driven by respective crosspoint gates in a duplicated matrix which is scanned by a duplicated, 10-stage binary counter stepped at a 10 kHz rate by 8 Á sec. pulses from a duplicated clock. The outputs of the clocks, the counters and the scanning amplifiers are all connected to fault detection circuitry. All the circuits are made up in integrated circuit format.

Title: Optical focus detecting apparatus
IPC: G02B7/36
Filed: 1975-05-14
Abstract: 1500385 Automatic focusing HONEYWELL Inc 14 May 1975 [27 Aug 1974] 20249/75 Heading H4D Optical apparatus comprising optical means for detecting the condition of focus of an image, and which may be used in automatic focusing apparatus for a photographic camera, is described. In Fig. 1 camera lens 1 focuses an image 2 in the vicinity of a film emulsion plane 3. Optical focus detector 4 scans and modulates the image by means of a rotating "radialled" spatial filler having random spatial frequency to produce a light pattern from which is obtained an electric signal which represents the focus condition. A reference signal 16 is also produced. The electrical signal is suitably multiplied with the reference signal at 6 and filtered and results in a D.C. output signal representing the focus condition which may be indicated at 7 and used to drive a servo control 8 which is arranged to maintain lens 1 in a position where image 2 is focused on plane 3. Fig. 2 shows the optical focus detector 4. Rotatable spatial filter disc 10 is inclined to the optical axis whereby it may scan the vicinity of plane 3. Filter 10 is disc, see Fig. 3, having alternate opaque and transparent sectors which are arranged in pairs of equal width each adjacent pair being of random width and each pair has an identical pair positioned diametrically opposite, i.e. the disc pattern comprises a mirror image to each side of any chosen diameter. The average light transmission is 50%, and at focus a peak signal is detected by photo-electric cell 14 twice per revolution. Disc 10 is driven by motor 11 which also drives a half opaque disc 12 the diameter of which is arranged to interrupt the light beam from source 18 to photo-electric sensor 16 simultaneously with the coincidence of disc 10 and focal plane 3 whereby a reference square wave signal is produced by amplifier 17. In Fig. 6, the responsive circuit comprises high impedance stage 20 connected to photo-electric sensor 14 which operates on a logarithmic characteristic insensitive to the image scene brightness. The detector signal is amplified at 21 and high pass filtered at 3 kHz at 22. The signal is then further amplified at 23 and fed to AGC control unit 24 which provides standard peak to peak level regardless of subject contrast. The signal is then detected and filtered at 26 and 27 and fed to phase detector 28, which reacts to any signal at the disc frequency to provide a D.C. output that depends upon the phase of the light flux waveform. The filtered direct current from the phase detector 28 may then be applied to meter 7, Fig. 1, to indicate the focus condition and is also fed to motor 30 which activates, via mechanical linkage 9, Fig. 1, movement of lens 1 and the camera objective lens (not shown), to an in-focus condition.

Filed: 1927-08-04
Abstract: 287,076. Flesch, H., (Assignees of Farb-& Gerbstoffwerke C. Flesch). March 14, 1927, [Convention date]. Sulpho-oxyfatty acids.-Sulphuric esters of dioxy-, trioxy-, and polyoxyfatty acids are produced from oxyfatty acids by introducing into the cooled and actively agitated oxyfatty acids sulphuric acid containing 5 to 10 per cent of sulphuric anhydride, and in the state of a very fine mist from spraying nozzles. In this way not only is ricinoloeic acid converted into sulphodioxystearic acid. but also dioxystearic acids, for example, the dioxystearic acid obtained by oxidizing iso-oleic acid, trioxy- and polyoxystearic acids may be converted into their sulphuric esters without the use of solvents. The sativic acid prepared from linoleic acid by means of permanganate may be esterified in this way.
