Title: Multi-stage image converter
Inventor: DOLON PAUL J
IPC: H01J31/50
Filed: 1966-02-25
Abstract: 1,131,813. Image converter tubes. RAULAND CORP. 25 Feb., 1966, No. 8508/66. Heading H1D. An image converter includes a number of cascaded image conversion stages enclosed within a single envelope, each stage comprising a radiation responsive input element which develops an electron image and an output element which produces a corresponding photon image, and at least one stage serves to magnify the image and at least another of the stages serves to diminish the image. If the first stage of a two-stage converter effects a magnification then the resolution of the final image is increased at the expense of the signal to noise ratio. Conversely, the signal to noise ratio may be increased to the detriment of the resolution by diminishing the image size in the first of the stages. Thus optimum resolution and signal to noise ratio conditions for any given image may be achieved by the appropriate magnification, which may be variable, at each of the stages. As shown, in a two-stage converter, the photoemissive input element 25 of the first stage is located adjacent the front window 15 of the glass envelope 10 which has an opaque coating and is prefabricated in sections, enabling electrical connections to components in the tube to be made through the junctions between sections. Photoelectrons from input element 25 are focused by electrode 40 and anode 43 on to the phosphor screen output element 32 which is coupled to the photoemissive input element 29 of the second stage by a fibre optic interstage coupling element 30. Similarly photoelectrons from input element 29 are focused on the phosphor viewing screen 34 set in the plane transparent end 17 of the glass envelope. With each of the adjustable electrode voltages at its most positive value, such as those indicated in the figure, an image 53 projected on to the first input screen 25 will form a final image 54 on the screen 34 as shown by the solid beam outlines: with each voltage at its least positive value the image 54 is formed as shown by the dashed beam outlines. If the magnification product of the two stages is to be a constant, including unity, for all electrode voltages then the voltage control units 48, 49 may be coupled to a suitable single control 52.

Title: Improvements in or relating to power lift systems
IPC: A01B63/10
Filed: 1962-03-06
Abstract: 994,992. Tractor power-lift mechanisms. INTERNATIONAL HARVESTER CO. March 6, 1962 [Aug. 14, 1961], No. 8554/62. Heading A1P. A tractor hydraulic power lift mechanism includes a device whereby the flow of pressure fluid from the ram is controlled so that the implement is lowered at a constant speed which is independent of the implement weight. A continuously acting pump 29 supplies pressure fluid through line 43 to a port 51 associated with a control valve 56. When this valve is moved to the left in the figure by means of a position control lever 18 acting through linkage 19, 20 and 27 pressure fluid is supplied through part 51 and passage 55 to open a poppet valve 60 and thence to the hydraulic ram piston 70. This moves rock shaft 5 to raise the implement until the linkage 24, 22, 20 and 27 operates to restore the valve to the neutral position. When the valve 56 is moved to the right in the figure by means of lever 18 the poppet valve is opened by the valve 56 engaging a stem 66 thereof and fluid is allowed to flow from the piston 70 through poppet valve 60, passage 55 and part 52 to a flow-controlling device 72. This device comprises a piston 81 having a metering portion 82 which is arranged to create a pressure differential between passages 77 and 78 whereby a piston valve 92 is moved to restrict the outlet port 75 so that a constant flow of pressure fluid is achieved. The piston 81 can be set by a control lever 88 and an extension 91 may be incorporated to make it operable by the position control lever 18. For automatic draft control the upper link 2 is connected by a resilient member 7 to a linkage 9, 10 which can be set by a hand lever 14 and which acts on the control valve 56. A by-pass valve comprising a ball 36 and a piston 40 has one end connected by line 37 to the pump and has the other end also connected to the pump through a line 45 having a restriction 44 therein. This other end also connects with a port 50 in the control valve, the port being connected in the by-passage 54 to exhaust when the valve 56 is moved to the left i.e. the 'raise' position, thus keeping the by-pass closed but being connected to the returning pressure fluid when the valve 56 is moved to the right i.e. the lower position, whereby the piston 40 is operated by the pressure fluid to move the ball valve 39 to open the by-pass.

Title: An improved process for working up the waste liquors of the cuprammonium silk stretch spinning process
IPC: D01F2/04
Filed: 1931-03-21
Abstract: In the recovery of copper from the precipitating liquid obtained in the cuprammonium silk stretch spinning process, the liquid is treated first with excess of alkali such as soda lye and then with a solution of a magnesium salt such as the sulphate, whereby a mud containing copper hydroxide and magnesium hydroxide is precipitated.  The bucking lye obtained during the preparation of the cotton may be used as the source of the alkali.  From the precipitated mud magnesium is dissolved out by acid, for instance by sulphuric acid, and the copper at the same time converted wholly or partially to an insoluble basic salt.  For this step the copper-bearing sulphuric acid obtained during the acidification of the filaments may be used.  The magnesium salt solution may be re-used for precipitation of more copper, and the basic copper salt be treated, as by washing with cuprammonium solution or by heating in air to say 400 DEG  C., to remove or destroy cellulose degradation products.  The purified basic salt, with or without further purification by solution in sulphuric acid and precipitation as basic sulphate by soda solution, may be again added to the cellulose solution.  A statement of the art refers to absorption of the copper from precipitating liquids by means of carbohydrates, cellulose, or wood meal, and to its precipitation, after expelling ammonia, as hydroxide.

Title: Improvements in or relating to the production of membrane filters
Inventor: MAIER KARL-HEINRICH
IPC: B01D1/02
Filed: 1960-03-12
Abstract: <PICT:0903270/IV(a)/1> Microporous membranes are made by applying a thin layer of a solution of a cellulose ester in a mixture of organic solvents differing in volatility to a support, evaporating the more volatile solvent, and passing the coated support through a bath of a liquid which is a non-solvent for the cellulose ester but is miscible with the less volatile solvent so that the latter is removed from the coating by diffusion into the liquid bath.  The process may be carried out continuously, using a moving support, e.g. an endless belt.  Evaporation of the more volatile solvent may be assisted by a current of air, preferably at 20 DEG -40 DEG C. and 50-70% relative humidity.  The diffusion bath is preferably held at 20 DEG -40 DEG C. and the bath liquid may flow in counter-current to the direction of movement of the coated support.  Suitable apparatus comprises an endless belt 1 supported on rollers 2, 3 and constructed of corrosion-resistant material with a very smooth surface.  Coating solution is applied from storage tank 4, delivery being controlled by valve 6 and weir 7.  The coated belt passes through a preliminary chamber 10, and then through the evaporation chamber 11 through which flows a current of air 12, 13.  The belt now travels through the diffusion bath 14 through which bath liquid flows in counter-current 20, 21.  The membrane is then stripped from the support, and passes over roller 15, between the heated rollers 16, through a drying passage 18 supplied with hot air, and is wound up on roll 19. Esters, ketones and ethers are specified as more volatile solvents, and alcohols as less volatile solvents.  In an example, a membrane is cast from a solution of cellulose nitrate in a mixture of methyl acetate, ethyl alcohol, sec. butyl alcohol, water and glycerine and passed through a bath liquid consisting of water with, optionally, up to about 20% glycerine.
