Title: Improvements in or relating to apparatus for liquid purification by reverse osmosis
IPC: B01D63/10
Filed: 1966-06-07
Abstract: 1,120,059. Reverse osmosis desalination apparatus. GENERAL DYNAMICS CORP. 7 June, 1966 [11 June, 1965], No. 25243/66. Heading B1X. A membrane lay-up for the separation of aqueous solutions by reverse osmosis comprises a system of flaps, each of which is a sandwich of spacer material 30, membrane 34 and backing material 38 with the backing material innermost, there being one continuous sheet of membrane (suitably of cellulose acetate) through all the flaps, the flaps being wound round a central hollow mandrel which is in fluid communication with the backing material but not with the spacer material. Fig. 2 (not shown) illustrates a stage in the production of the layup from feed rolls (49), (50), and (51) of spacer material, membrane, and backing material respectively, the flaps being held in place on jig (52) by pins (46) and (56). When complete, the ends are sealed so that liquid cannot pass directly into the backing material from the spacer material, and then the flaps are wound on to the central mandrel (26), the outer diameter being inside the ring of roller pins (58). Fig. 1 (not shown) shows the unit in place in pressure shell (72). which also comprises cap (74) feed inlet (78), waste outlet (80), and product outlet (94) in communication with apertured mandrel (26) around which the lay-up is wound. The unit is wrapped with tape (70) and liquid is prevented from passing directly from the feed space to the waste outlet by a sealing ring (82). Feed liquid passes under a pressure greater than the osmotic pressure of the solution from the inlet (78) down the spacer material between the membrane folds and solvent diffuses through the membrane to the backing material whence it passes through apertures (40) into the central mandrel which is sealed at the top by plug (48). The backing material may be graphite cloth, glass felt, or sized silicon carbide or sand on plastic felt, but for pressures not exceeding 500 p.s.i. nylon, polyester, rayon, rayon viscose or acrylic fibrous material may be employed; the spacer material is suitably a woven screen grid. The lay-up and apparatus is of particular application in the desalination of brackish or sea water.

Title: Electron diffraction apparatus
IPC: H01J21/14
Filed: 1948-09-29
Abstract: 669,997. Electron diffraction apparatus. GENERAL ANILINE & FILM CORPORATION. Sept. 29, 1948 [Nov. 15, 1947], No. 25402/48. Class 39 (i). [Also in Group XX] Electron diffraction analysing apparatus comprises means for periodically varying the velocity of the electron beam incident upon the specimen under test, means for collecting electrons diffracted from the specimen at certain of said velocities and means, e.g. a cathode-ray tube for visually indicating the magnitude of the number of collected electrons against the corresponding incident beam velocity. As shown, the beam from an electron gun 5 after acceleration and collimation by electrodes 12, 13 passes to the anode 33 through circular apertures in solid metal housings 15, 15<SP>1</SP> between which the specimen 16 to be analysed is suspended by a forked member 24 from a removable cover-plate 26. Electrons reflected from the specimen at a predetermined angle pass through a ring-shaped slot 17 cut in the housing 15 at the appropriate angle to a collector ring electrode 19 having a concave collecting surface. Electrons passing through a specimen and diffracted at the same angle are similarly collected by an electrode 19<SP>1</SP> located in housing 151 behind a similarly-angled slot 171. The electrons collected by either the electrodes 19 or 191 are passed by a selector switch 21 through a resistor 38 and biasing source 39 to earth, and the voltage developed across AB, proportional to the electron flow from the selected collector electrode, is applied to the Y-plates of a cathoderay tube, the X-plates of which are fed from a tapping 37 on the secondary of a transformer 30 which also feeds the accelerating electrodes in the tube 4. The electron beam will flow with varying velocity during positive alternations of the supply and since the diffraction pattern, Fig. 2 (not shown), is repeated twice during each positive alternation of the supply, known means including a choke 40 are used to suppress one of the patterns. In a modification, Fig. 3 (not shown), the diffraction pattern is recorded. The peaks only of the pattern may be recorded by first differentiating the collected current.

Title: Treatment of aluminium
Inventor: BRYAN JOHN MAURICE
IPC: C25D5/44
Filed: 1949-10-06
Abstract: As a preliminary treatment to processes such as for example, oxidation processes, or plating chemically a metal surface consisting at least mainly of aluminium is treated to remove the surface film of oxide, by etching in an aqueous etchant of high total acidity containing both free chlorine ions and un-ionized but ionizable chlorine and a substance providing hydroxy groups, the chlorine ions and the hydroxy groups being provided at least in part by at least one chlorine derivative of an aliphatic acid or of a hydroxy-organic compound, or the chlorine ions being provided at least in part by hydrochloric acid or a chloride in acid solution and the hydroxy groups being provided at least in part by a hydroxy-organic acid or other hydroxy-organic substance, and if desired also in part by an inorganic acid containing hydroxy groups or a salt of such acid. Examples of chlorine derivatives of aliphatic acids or hydroxy-organic acids are mono-di-, and trichloracetic acid, mono-di- and tri-chlor-lactic acid, 2-chloro-1-hydroxy-butyric acid, 3-chloro-1-hydroxy-butyric acid.  1-chloro-2-hydroxy-isobutyric acid, and 1 - chloro - 2 - hydroxy - 1 methyl-succinic acid.  A suitable chloride is aluminium chloride, suitable inorganic acids are phosphoric acid and suphuric acid, and suitable hydroxy organic acids are citric, tartaric, and lactic acids.  Examples of other hydroxy organic compounds are glucose and dextrin.  The metal surface may be cleaned before treatment by an alkaline solution, for example a 5 per cent. solution of sodium hydroxide.  After etching the surface may be washed or rinsed with an inert solvent, examples of which are dioxane and ketones.  Alternatively the etched surface may be washed with water.  For plating by chemical displacement the etched surface should be washed thoroughly in an inert liquid, then finally given a time-controlled rinse in cold water.  For nickel plating the bath may consist of a solution of nickel suphates, nickel chloride, ammonium citrate and a substance known under the Registered Trade Mark "Perminal Bx".

Abstract: 655,596. Inductive control of consumption apparatus. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Oct. 4, 1948, No. 25772. Convention date, Oct. 4, 1947. [Class 38 (iv)] Two or more A.C. circuits such as lamp loads 4, 5 are energized alternately at a low frequency by modulating the A.C. supply 1 by means of saturable reactors 2, 3, each provided with a self-magnetizing winding 6 and a control winding 12, the latter forming part of an oscillatory circuit comprising a condenser 11 connected to the D.C. terminals of a bridge rectifier 9 connected across the load 5 associated with the other reactor 3, the arrangement being such that whilst the precharged condenser 11 is discharging over resistance 15 through winding 12 in the direction opposite to that shown and hence increase the reactance of reactor 2, condenser 10 is being charged through winding 13 in the direction shown and hence decrease the reactance of reactor 3 so that eventually lamps 4 and 5 are respectively extinguished and energized and the procedure then reversed. Resistanees 16, 17 may be shunted across the loads to ensure maintenance of oscillations in the event of a lamp failure. Alternatively, an opposing control winding may be included on each reactor and included in circuit with the aforementioned control winding on the other reactor (Fig. 2, not shown). Condensers 18, 19 of the same value as condensers 10, 11 may be shunted across the control windings to improve operation. The reactor may either be included in series with its load as shown, or in series with each other, but in shunt with its load (Fig. 4, not shown), in which case lamp energization is effected when the associated reactor is unsaturated. In another arrangement (Fig. 3, not shown), one rectifier only is used which supplies an assisting control winding on its associated reactor and an opposing control winding on the adjacent reactor. An arrangement is described (Fig. 5, not shown) for operating more than two lamps. Specification 634,210 is referred to.
