Abstract: 1,266,868. Purifying liquids by electrodialysis. H. B. FRANKLIN. June 11, 1969 [June 24, 1968], No.29927/68. Heading C7B. An electrodialysis apparatus for purifying a liquid comprises an electrode chamber having an anode and a cathode separated by a diaphragm, the anode and/or cathode having a roughened, slotted or apertured surface provided with a porous impregnation containing an agent capable of removing specific impurities by mechanical surface filtration and/or chemical combination from the liquid. One electrode, preferably the cathode, and the diaphragm, preferably porous, is arranged in a non-conducting e.g. plastic meshed cradle designed to ensure the electrodes are separated one above the other e.g. the anode by a predetermined distance. For purifying plant juice separated from fibrous material, an anode, e.g. a carbon block with drilled apertures on the surface facing the cathode positioned above, has the surface impregnated with a matrix containing graphite and carbon particles, e.g. produced by heating a mixture of sugar and graphite, with or without phosphoric acid, out of contact with air, impregnated with the agent, e.g. dithiazone for removing Cu or potassium persulphate for removing S compounds; dithiazone removes Pb at a cathode. The impregnation also protects the electrode. The purified plant juice may be heated and/or adjusted in its pH to coagulate and precipitate solid protein and the latter separated.

Abstract: 1,267,121. Gas chromatography. LKB-PRODUKTER AB. 13 April, 1970 [21 April, 1969], No. 17484/70. Heading B1X. A molecular separator through which the separated effluent fractions from gas chromatograph G pass before entering mass spectrometer M comprises a retractable slide 7 which can be inserted between inlet nozzle 5a and output nozzle 6a of vacuum chamber 12, and which is manually operable by knob 9 and locking screw 10 through bellows 8. When the slide is inserted between the nozzles, the chromatography column connected to the separator may be switched or changed without requiring the vacuum in the separator to be released. In the embodiment shown, the separator has two chambers, chamber 12 being evacuated by a mechanical pump and chamber 13 by an oil diffusion pump. In a second embodiment (see Fig. 2, not shown), the second chamber is dispensed with, the effluent from the first chamber passing directly to the ion source of the spectrometer which is connected to high vacuum through connexion (16).

Abstract: 1288544 Rotary shaft seals; lubricating SKEGA AB 28 Jan 1970 [29 Jan 1969] 4164/70 Headings F2A and F2B A device for sealing a rotary shaft comprises a resilient lip seal 19 and a flexible substantially inextensible sleeve 35, the arrangement being such that when attached to a housing 13 and the space 25 is filled with lubricant, rotation of the shaft causes rotation of the seal and a twisting of the sleeve to exert a pressure on the lubricant therein. The end of the sleeve 35 adjacent the housing is sealed to the shaft by lip seals 15, 17. The sleeve may be cylindrical or conical and made of polyethylene, polyester or nylon. The space 25 is charged with lubricant through a nipple 27 and reducing valve 31. Upon rotation of the shaft 11, the seal 19 will follow the shaft in the direction of rotation on account of its frictional engagement and cause the sleeve to shorten as it twists making folds 37, 39. As the sleeve shortens, the seal 19 is displaced along the shaft. The pressurized lubricant in the space 25 serves to prevent foreign particles from entering the space as it slowly leaks past seals the seals shown being, for example, in a pump. The device may also be used for lubricating and sealing a ball or other bearing; in such an arrangement, the middle seal 17 is replaced by the bearing. The sleeve may be attached to the housing by gluing, welding, binding or by clamping with hose clips. The lip of the seal 19 may be directed in the opposite direction to that shown.

Abstract: 1288597 Light modulation; magneto-optic storage arrangements GENERAL ELECTRIC CO 9 Oct 1969 [9 Jan 1969] 49639/69 Headings H3B and H4F [Also in Division G5] An element 2 in a display system comprises a thin ferromagnetic film 23 constructed to have a regular magnetic domain structure which produces optical grating lines in an adjacent colloid 24 of ferromagnetic particles, and the grating lines in any elemental area may be rotated in the plane of the film by application thereto of a suitably directed magnetic field above a threshold value so that light from a source 1 is reflected and either passes through a viewing window 4 (line a, area A) or does not (lines b, area B). Two orthogonal sets of conductors 5, 6 (35, 36 in Fig. 4) provide a D.C. magnetic field at any selected area using XY addressors 34, 46, but since the plot of domain rotation against D.C. magnetic field is moderately linear, substantial cross-talk with other areas in the same X or Y lines occurs. The corresponding plot for an A.C. field shows a steep rise of rotation angle at a predetermined A.C. field strength, Fig. 5 (not shown). Therefore in the arrangement shown in Fig. 4 the resultant D.C. field, which is in either the X or Y direction according to the direction of current in lines 35, is chosen so as to be less than the threshold value, but is augmented by an A.C. field, also less than the critical value, from Helmholtz coils 39 along an axis α, commonly at 45 degrees to the X and Y axes, so that the domains are rotated to lie along either the X or Y axes, areas C and D, corresponding to write or erase operations, respectively. The A.C. field may be continuous, or pulsed simultaneously with the D.C. pulses from the addressors 34, 46, and in either case may contain a lower frequency A.C. component of above threshold value to provide a relatively slow automatic erasure, Fig. 3 (not shown), obviating the need for current reversal in line 35. In modifications, the A.C. field is directed along the Z or Y axes, Figs. 6 and 7 (not shown), and may be provided by means other than a Helmholtz coil, e.g. a flat field coil below the conductors 5, 6, or parallel conductors integral with the element 2, Figs. 8 and 9 (not shown). As described, the film is an 85% nickel 15% iron permalloy film, electroplated to a thickness of 20,000-30,000  over sputtered gold, using a sulphate bath. Application of a negative magnetostriction and a tensile stress to the film gave magnetostriction and internal stress values of opposite sign to form fine line changes in the magnetic field gradient normal to the film plane, corresponding to a striped domain structure at the film surface.

Abstract: 1295963 Reproducing three-dimensional objects I MORIOKA 10 March 1970 11540/70 Heading G2C A three-dimensional object is reproduced by projecting thereon sets of parallel lines from a plurality of parallel line screens, photographing these line patterns, projecting the photographed pattern together with the original sets of parallel lines on to a body of material such as clay, and manipulating this body until the projected photographed lines coincide with the projected original lines. Fig.1 shows an arrangement of three projectors P 1 , P 2 , P 3 , each of which projects a pattern of parallel lines on a screen S on to an object O. The screens are as in Fig.2 (not shown) the lines having small blobs in distinctive arrangements, so that one line may be distinguished from another. If the object O is a spherical or other curved surface, then the pattern of lines thereon will be a series of curves. These are photographed by three cameras C 1 , C 2 , C 3 , and the photographs developed to form positive prints. The cameras C 1 , C 2 , C 3  are now replaced by three further projectors P 1 ', P 2 ', P 3 ' which project the curved line patterns of the positive prints on to the clay body O'. At the same time, projectors P 1 , P 2 , P 3  project the patterns of the parallel line screens S on to the clay body. The clay is manipulated, i.e. by adding or taking away material, until the two sets of patterns coincide, when the body O' will have the same contours as the original object O.

An actuating lever 41, also longitudinally movable, includes a strip 43 provided with slots 44 for receiving rollers 52 mounted on struts 50, the struts being pivoted to the veeblock arms 35. The lever 41 is operated by an hydraulic ram 47. An accumulator device 60 is provided for each pair of vee-blocks 20, 21 and prevents an article being carried towards blocks already occupied. The device includes a plate 61 which, when depressed by an article, causes the roller 52 of the adjacent upstream vee-block unit 36 to be raised out of its slot 44. Accordingly this unit will be inoperative. When the ram 47 extends, the actuating lever 41 is moved to the left, Fig. 1, and the veeblocks 36 are raised by the struts 50 and the arms 35. Further extension of the ram moves both the lever 41 and the frame 26 to the left so that an article on the blocks 36 is carried to the left. The ram then contracts, the lever 41 alone moves to the right and the blocks 36 are lowered to deposit the article on the next pair of blocks 20, 21. The ram finally draws the frame 26 to the right ready for a further cycle. The reversal of the ram may be effected by limit switches which control pressurized fluid to the ram.

A polymer monofilament 1 is drawn from a spool 2 through a sizing die 4 and a reservoir 6 containing a suspension 7 of a refractory material, e.g. metallic or ceramic powders such as stainless steel, alumina, glass-ceramic and silicon. The solvent may be aqueous or organic and includes binding agents. The coated filament is then partially dried by jets 14 of cold air followed by passing through a device 15 to which warm air is supplied by pipe 16. Then jets 18 of cold air are directed on to the filament before it is severed into rods by a conveying device 22. This device comprises a pair of duplex endless chains 25, 25A which accommodate cutting elements 26 and anvils 27. Each anvil has a V-shaped notch (27A), Fig. 2 (not shown), conforming to bevelled portions (26A), (26B) of element 26, the central zone of the notch having a cut-away portion 33 to receive the filament 1. The stationary cams 29 cause a gradual gripping of the filament prior to the cutting into rods 23. The rods are then packed into a device 26, Fig. 3, comprising a casing 37, respective top and bottom plates 39, 38, a refractory core 40 and a moulded rubber annulus 42. The annulus is held in a rigid container 43 which has an array of holes 45 in its wall to allow pressurized fluid from inlet 44 to pressurize the annulus and hence compact the assemblage of rods into hexagonal, coated rods (23A), Fig. 5 (not shown). The assemblage is then heated to remove the organic filamentary core of each rod and the rods are subsequently sintered or heat treated in a reactive atmosphere.
