Abstract: 1,233,653. Light guides. NIPPON SELFOC CO. Ltd. July 3, 1969 [July 6, 1968 (2)], No.33599/69. Heading G2J. A light beam deflection control system comprises a fibrous converging light guide 101 in which the refractive index has a maximum value along the optical axis and gradually decreases to a minimum value at the circumference; the specification assumes a square law variation of the index with the radial distance and quotes a formula which relates the values of the displacement X 2  and angle p 2  of a light beam 104 as it leaves the guide to the corresponding values X 1  and p 1  as it enters the guide. If the length of the guide is suitably chosen then the angle of emergence p 2  can be made independent of the angle of incidence p 1  but proportional to the displacement X 1  . The guide may be used to magnify the small deflections produced by electrically controlled deflection devices Fig. 2,  (not shown) by setting the deflector a considerable distance from the guide; X 1  is then of suitable size even if the deflection p 1  is small and if the constant of proportionality between p 2  and X 1  is fairly large then p 2  will be much bigger than p 1  . Two or more fibres may also be used in series or crossed relationship.

Abstract: 1,239,620. Ophthalmic lenses. SOC DES LUNETIERS. Oct. 28, 1968 [Oct. 30, 1967; July 26, 1968], No. 51043/68. Heading G2J. If an eye 1, Fig. 1, looking at an object at infinity along the optical axis 3 of an ophthalmic lens 2 finds that the correction for ametropia is perfect and the lens 2 forms an image at R o , in the absence of eye 1, then when the eye 1 rotates about its centre of rotation O through an angle U the image of an object at infinity should be formed by lens 2 at a point R on sphere 5 centred at O and passing through R o , but in practice a spherical surfaced lens 2 forms a sagittal focus at S and tangential focus at T with the circle of least confusion at I. Accordingly the present lens has a surface shaped to eliminate or reduce the astigmatism TS and/or the field curvature I R particularly in the case of high power toric lenses such as those having a power greater than 12 D required in aphakia. This is achieved by taking a circle, passing through H and having a radius of approximately 27 or 28 mm, and evaluating along the two principal meridians the distances required from points on the circle K, G, etc. to the corrected lens surface and tabulating them as a function of angle U. For a progressive foci lens the correcting surface is evaluated along the vertical meridian on the basis of an object distance which gets progressively less as the eye looks downwardly, or for a lens of two or three focal lengths it is evaluated for the appropriate two or three object distances such as infinity, intermediate and reading distances.

Abstract: 1,252,666. Fluid-pressure servomotor systems. DEERE & CO. Jan.14, 1969 [Jan.15, 1968], No. 2172/69. Heading G3P. Supply fluid in line 47 can pass to chamber 19 and through passage 36 in relay spool 21 to the interior of the latter where it leaks past lands 38, 39 of pilot spool 37 into line 45. The back pressure in line 45 is determined by the setting of regulator 46 and acts on diaphragm 43 to balance the force of a tension spring 40 connected between pilot spool 37 and the rod of a double-acting piston 5 whose opposite sides are controlled by the relay spool 21 which can connect passages 10, 11 selectively to supply chamber 19 and exhaust chamber 18 or 20. Adjustment of spring 54 of regulator 46 varies the pressure acting on diaphragm 43 so that pilot spool 37 moves to connect one of chambers 16, 17 to supply and the other to line 45 such that the relay spool follows the pilot spool movement. Piston 5 thereby moves until the force of spring 40 balances the new force exerted by diaphragm 43. The exhaust chambers may lead into line 45 instead of into separate lines 47, 48.

[Also in Division C1] In effecting an exothermal chemical reaction in the presence of catalyst which is present in a reactor in the form of a bed having at least two sections, catalyst constituting at least one section of the bed, but excluding the first section of the bed, is prepared by reduction of catalyst precursor in oxidised form by hydrogen present in gas containing hydrogen and other components for effecting the exothermal reaction, hot reducing gas leaving the first section of the bed, which section consists of catalyst in reduced form, in part being recycled, after being mixed with cooler reducing gas introduced through a nozzle or nozzles of an injector recycling system, through the first section of the bed and in part being passed directly to and through other section or sections of the bed, which section or sections initially contain(s) catalyst precursor in oxidised form, the temperature of the reducing gas entering the other section or at least one of the other sections of the bed being regulated, for example by indirect heat exchange and/or by mixing cooler gas with the reducing gas leaving the preceding section of the bed, to a temperature lower than the temperature of the reducing gas leaving the first section of the bed. The catalyst constituting the first section of the bed is prepared, i.e. reduced from the precursor oxide form, either prior to being placed in the reactor or in situ in the reactor, apparently by an conventional known method, prior to preparation of the catalyst constituting the other section or sections of the bed as described. As illustrated in the drawing, cold reducing gas is passed via line 1, heat exchanger 2 and electric preheater 3 to the nozzle of mixing injector 4 where it mixes with hot reducing gas which has passed through first section 5 of the catalyst bed and recycle line 9; after passing through the first section of the catalyst bed, the resulting mixed gas in part is recycled to the mixing injector via the recycle line and in part is passed successively through further sections 6, 7, 8 of the catalyst bed, through the heat exchanger wherein cold reducing gas is preheated, and through discharge line 14 for further (unspecified) processing. Cold reducing gas is introduced, as required, via lines 10, 11, 12, 13 to regulate the temperature of the gas entering the various sections of the catalyst bed. As exemplified, the exothermal reaction is the synthesis of ammonia from hydrogen and nitrogen in the presence of elemental iron catalyst derived from iron oxide catalyst precursor.
