IPC: H01J29/84
Filed: 1954-03-17
Abstract: 747,707. Ion-trapping in cathode-ray tubes. GENERAL ELECTRIC CO. March 17, 1954 [March 18, 1953], No. 7791/54. Class 39 (1). vided with pole pieces 20, 21 to deflect the electrons back to the tube axis. The magnet structure is supported by a metallic cup 18, the pole pieces 20, 21 being held by shoulders 22, 23, 24, 25 and being spot welded at their ends to parts 28. The pole pieces have recesses into which the ends of the permanent magnet 27 project. The opposed surfaces of the pole pieces may be curved, e.g. cylindrical, to eliminate strong concentrations of magnetic flux which would occur at sharp edges. An electrostatic field having a transverse component is set up between accelerating electrode 5 and anode 6 which have inclined adjacent ends. Diaphragm 30 ensures that eccentric aperture 29 is in a field-free region provided that the spacing between the lower end of cup' 18 and diaphragm 30 is greater than or equal to the diameter of aperture 31. The gun electrodes, comprising cathode 2, control electrode 3, accelerating electrode 5 and anode 6 are on a common axis which is preferably slightly tilted with respect to the tube axis so that the beam is returned exactly along the tube axis by the magnetic deflecting field. Electrodes 3, 5, 6, cup 18 and diaphragm 30 are of non-magnetic material such as stainless steel or copper-nickel alloy. In manufacture magnet 27 is magnetized after the gun has been assembled in the tube. The beam after emerging from the gun passes through a magnetic focusing assembly 7 inside the tube envelope, as disclosed in Specification 720,776. This assembly comprises a plurality of cylindrical permanent magnets 10 supported between a pair of annular pole pieces 8, 9, and a '.' lens member 11 " carried by cylinder 12 which is an extension of anode 6.

Abstract: 553,196. Colour photography. KODAK, Ltd., and BRANCH, L. E. T. July 25, 1941, Nos. 7993/41 and 1220/42. Drawings to Specification. [Class 98 (ii)] in the subtractive reproduction of a multicoloured original by a photographic or photomechanical process, colour correction is effected by making three colour-component records from the original, by contact or projection printing on one support or on separate supports, while it is in register with a mask having a single image which, in order to compensate for the undesired absorption of'light of one primary colour by one colour-component record is either (a) a red component record coloured minus blue, or (b) a red component record coloured minus green. or (c) a green component record coloured minus blue, or (d) a green component record coloured minus red. The masking image is not formed in a sensitive layer in which a colour-component picture record is made, although it may be formed, e.g. as described in Specification 547,519, integral with a layer or layers containing colour component picture records ; and it has an absorption gamma as measured by light of the primary colour undesirably absorbed, and for which correction is being made, which is not more than 50 per cent less or 50 per cent greater than the absorption gamma, measured by the same light, of the component colour image which exhibits the said undesired absorption. Mask (a) compensates for blue light absorption by the cyan image, mask (b) for green light absorption by the cyan image, mask (c) for blue light absorption by the magenta image, and mask (d) for red light absorption by the magenta image. The correcting process may be extended by using in the reproduction a mask having any two of the above-defined single images in register, e.g. in superimposed layers on a single support or in a mixed-grain emulsion layer. The correction may be directed towards compensating for the undesired light-absorption of the dyestuffs to be used in the copy, or of those used in the original if this is itself a multicolour reproduction, or of both, the gamma of the mask in the last mentioned case being appropriately raised. The masking images may be coloured by direct or indirect colour development, the developed silver being removed. The colour of the masking image may be adjusted to compensate for incorrectness in the gamma of one of the records, e.g. the effective contrast of the cyan image may be reduced by including in mask (a) or (b) above a proportion of cyan; and in this case the mask may be made by colour development of a single emulsion, using a mixture of colour couplers of the same kind as those used in producing the original or the copy. Specifications 427,516, 427,518, 427,520, 458,665, 478,942, 493,952, 494,341, 507,841, 512,608, 517,416, 537,864, and 551,614, also are referred to.
Patent GB-1120007-A (GB)
Title: Moulding metal
IPC: B21D26/055
Filed: 1966-02-25
Abstract: A method of forming an article of metal comprises conditioning the workpiece to exhibit superplasticity (i.e. exceptional elongation without facture) and employing a fluid pressure difference across the workpiece to form it to the desired shape. Various Al-Zn, Al-Cu, Al-Si, Cu-Zn alloys are listed which are capable of exhibiting super-plasticity.  A Zn-Al alloy was made super-plastic by heating to 600 DEG F. for at least one hour, quenching in water to a metastable state, and re-heating to a working temperature of 520-525 DEG F. at which the workpiece may be formed by pressure or by evacuating, through passages, the interior of a die.  Any metastability remaining in a part formed of a non-eutectic alloy may be removed by heating the part to a stable phase and allowing it to cool slowly.

Abstract: 570,040. Refining glyceride oils. CLAYTON, W. L., FLEMING, L., WHITTINGTON, H., FUESLER, J. P., CANNAFAX, D., SUMNERS, D., JOHNSON, J. M., ODEN, S., and ANDERSON, W. L., (trading as ANDERSON, CLAYTON & CO.). June 18, 1942, No. 8371. Convention date, Oct. 3, 1941. [Class 91] The process described in Specification 537,704 for refining glyceride oils wherein a positively charged colloidal suspension of colouring matter in the oils is removed by admixing with the oil an aqueous solution containing a negatively charged colloidal suspension in an amount such that the electrical charge is approximately neutralized, is modified by forming the added colloidal suspension in situ in the oil by dissolving directly therein a metallic compound in a form which will react with an alkaline agent to form the negatively charged colloidal suspension and intimately mixing the alkaline agent with the solution. In a modification for use where the colouring matter is electrically neutral, the colloidal suspension may be produced by the addition of water to a hydrolysable metallic compound instead of the alkaline agent. The refined oil is then separated from the added materials and the impure colouring matter such as by centrifuging as described in the earlier Specification. The variations in operation of the process, such as by mixing the oil solution and the alkali in mist form and working in a one or two-step procedure to also remove the free fatty acids are as described in Specification 537,704. Suitable metallic compounds soluble in the oils which will form these oxides or hydroxides with the alkali or water include such compounds as trimethyl, diethyl, and tridodecylaluminium, tetramethyl, and tetraethyl-tin, and chlorides of tin, titanium, and aluminium.

Title: Process for the recovery of high percentage acetic acid from solutions of acetyl cellulose in acetic acid
IPC: C08B3/26
Filed: 1927-03-28
Abstract: 268,778. Verein f³r Chemische Industrie Akt.-Ges. April 1, 1926, [Convention date]. Acetic acid.-Part of the acetic acid is recovered from solutions of cellulose acetate in acetic acid without causing gelatinization by subjecting the solution at 90-100‹ C. to distillation, under a vacuum which is increased as the distillation proceeds so as to maintain lively boiling until the temperature falls to about 50‹ C., when about 20 per cent of the acetic acid will have evaporated. The solution may then be heated to 90-100‹ C. and the process repeated, when about the same amount of acetic acid is again recovered. The acetic acid is condensed to a liquid of about 92-93 per cent strength. The viscous solution of cellulose acetate remaining is precipitated with water or aqueous solutions and yields a product of satisfactory properties. The cellulose acetate in the initial solution may be in the acetone-soluble state, or, since saponification occurs during the process, it may be insoluble in acetone, or may be in a state in which the saponification has not progressed to the desired final acetic acid content. The Specification as open to inspection under Sect. 91 (3,) (a) states that the distillation is effected preferably under reduced pressure. This subject-matter does not appear in the Specification as accepted.
