Title: Improvements in the manufacture of hydroxy benzaldehydes
IPC: C07C45/64
Filed: 1924-03-19
Abstract: Salicylaldehyde and m-hydroxybenzaldehyde are prepared by reducing crude nitrated benzaldehyde with hydrosulphite and, without boiling off the sulphur dioxide, diazotizing and distilling the diazo product in a current of steam, the m-compound being extracted from the residue and the o-compound from the distillate.  In an example benzaldehyde is nitrated at low temperature with nitric and sulphuric acids, the mixture poured on to ice, washed with water and dilute soda, reduced with sodium hydrosulphite, the reduction mixture treated with sulphuric or hydrochloric acid and sodium nitrite and the diazo solution decomposed by dropping into dilute sulphuric acid through which a current of steam is passing.  Salicylaldehyde and some anthranil are recovered from the distillate by extraction with a solvent and the aldehyde separated by solution in alkali, filtering and reprecipitation by acid.  The m-hydroxybenzaldehyde is separated from the residue in the still by filtering off the tar and extracting with ether.  Specification 22398/09 is referred to.

Title: Improvements in Flying Machines.
Inventor: ANTOINE TONY
IPC: B64C3/38
Filed: 1916-05-18
Abstract: 113,100. Antoine, T. May 18, 1916. Steering.-Aeroplanes having two or more supporting planes adjustable about axes near their front edges, have the angle of incidence of the planes adjusted by diagonal tension members extending between the planes longitudinally of the machine and connected to pulleys mounted on rotary shafts carried by the planes. Figs. 3 and 4 show respectively a side view partly in section and an underneath plan of a biplane wing. The upper and lower planes are pivoted to front and rear struts c<1>, e and are stayed by diagonal members g, g' of adjustable length. A pair of members g extends from the upper end of the rear spar to two pulleys i, i<1> on a shaft h supported by the front spar a<1> of the lower plane. The member g' passes around a pulley y carried by the lower plane and is attached to a pulley i<2> on the shaft h so that rotation of the shaft causes one diagonal to be shortened as the other is lengthened. The interplane struts are stayed transversely by the usual cross-bracing. The angle of incidence is changed by turning the shaft h through gearing from the pilot's seat or by raising and lowering the rear spar of one of the planes. The latter movement may be effected by pivoted cams having peripheral flanges bearing against one or more rollers on the lower plane or on one of the struts e. In the case of multiplanes, the planes may be arranged one behind another at different levels and interconnected, or one or more may be fixed and the remainder adjustable.

Title: Improvements in the preparation of protein derivatives and photographic emulsions
IPC: G03C1/047
Filed: 1948-03-08
Abstract: A cyano-ethyl derivative of a protein or protein derivative is prepared by reacting the protein or protein derivative in solution with acrylonitrile.  The protein may be gelatin, degraded or hydrolysed gelatin, gelatin having a substantial degree of polymerization (e.g. calfskin gelatin), bone gelatin, pig gelatin, casein, zein, soyabean protein, blood albumen, globulin, edistin, or egg albumen.  The cyanoethyl derivatives may be hydrolysed or reduced after preparation.  The reaction may be effected in aqueous solution, in ethyl alcohol or other lower aliphatic alcohol, or in formamide as described in Specification 649,548, and in presence of an alkali metal (e.g. sodium) hydroxide, or in presence of ammonia or an organic base (e.g. methylamine, pyridine, or tetramethyl- or tetraethyl-ammonium hydroxide. Heating facilitates the reaction.  In example 1, an aqueous solution of glue of pH 10 is mixed at 110 DEG F. with an acetone solution of phthalic anhydride, the pH is raised to 11 by adding dilute sodium hydroxide solution, acrylonitrile is added, the mass is stirred for 2 hours at 110 DEG  F. and the pH is adjusted to 6.0. In examples 2 to 4, hydrolysed gelatin, calfskin gelatin and casein are similarly reacted with acrylonitrile.  In example 5, blood albumen is treated with acetic anhydride, the pH being held constant at 10.5 by addition of dilute alkali, and is then reacted with acrylonitrile.  In example 6, casein is similarly reacted first with methacrylic anhydride and then with acrylonitrile. In example 7, casein is first reacted with Crocein Orange acid chloride (added in formamide and prepared by reacting Crocein Orange with chlorosulphonic acid), and then with acrylonitrile. In examples 8 and 9, zein is reacted with acrylonitrile, in the second case using formamide and tetramethylammonium hydroxide. In example 10, casein is reacted with acrylonitrile.  In example 11, casein is first reacted with benzenesulphonyl chloride and then acrylonitrile.  In example 12, blood albumen is first reacted with phthalic anhydride and then acrylonitrile.  In example 13, casein is first reacted with methacrylic anhydride and then acrylonitrile.  Specification 649,544 also is referred to.

Abstract: 1,029,987. Web coating apparatus. EASTMAN KODAK CO. Feb. 22,1963 [Feb. 23,1962], No. 7188/63. Heading D1L. A method of decreasing the thickness of a layer of liquid supported on a web comprises relatively moving the web and a flexible sheet in a manner such that one end of the sheet trails over the layer in face to face contact therewith, the length of sheet in contact with the layer and the speed of the relative motion being such that said end of the sheet converges towards the web under the action of the Bernoulli forces to a distance of separation from the web at the trailing edge of the sheet less than the original thickness of the layer. In the arrangement shown web 10, the undersurface of which is wet with liquid 12 is moved in the direction of the arrow a liquid removing squeezee member 11 mounted on bar 13. The physical forces acting upon the liquid, including Bernoulli forces, surface tension, capillarily, adhesion and cohesion co-operate to hold the squeezee member 11 in contact with the liquid 12 and to remove excess liquid. The squeezee member 11 is preferably resilient and may have further resilient members urging it into contact with the liquid. It may also be provided with a downwardly extending lip at its forward end, to prevent any further liquid subsequently applied to the web from running back and contaminating the liquid 12.

Filed: 1969-02-11
Abstract: 1,207,283. Electrode materials and processing; photomultipliers. RCA CORPORATION. 11 Feb., 1969 [27 Feb., 1968], No. 7399/69. Heading HID. A method of making a photoemissive electron tube, e.g. a photomultiplier tube, having a photo-cathode film including one or more alkali metals, comprises, after the formation of the photo-cathode, baking the tube at a temperature between 100 C. and 175 C. for a period between 100 and 300 hours, evacuating the tube at least during part of the baking period, and hermetically sealing the tube envelope. The baking may be performed at sequential temperature steps of 135 C., 145 C. and 175 C., each step lasting 100 hours with the evacuation of the tube occurring only during the first two steps. In the photomultiplier tube 10 shown single or polycrystalline aluminium oxide window 18 has a photocathode 20 formed by depositing at 10<SP>-7</SP> Torr an antimony layer through tubulation 28 and which is successively sensitized at 160 C. by potassium and then caesium, tubulation 28 then being sealed at 74. The tube 10 and an ion pump 49 attached to tubulation 28 are then placed in a furnace for the baking process, after which the tubulation 28 is pinched-off in the region 80 to remove the ion pump and seal the tube when the pressure therein is about 10<SP>-12</SP> Torr. The baking process enables the tube to be operated for extended periods in environments having a temperature as high as 200 C. A series of dynodes 22 on rings 24 separated by ceramic rings 16 extend between focussing electrode 26, which forms an electrostatic lens field for directing photo-electrons on to the first dynode array, and the electron collector.

Title: Improvements in and relating to knitted fabrics
IPC: D04B21/10
Filed: 1945-03-23
Abstract: Knitted fabrics of the kind described in U.S.A.  Specification 2,205,581 are treated with a cellulosic composition so that a cellulosic film bridges the space between the elongated loops, holding the two sides together, restricts movement of warp threads within the loops under ordinary conditions of use and laundering, and sets the shape of the meshes, which are hexgonal, without closing the meshes in the fabric.  Suitable compositions to be applied to the fabric are solutions of cellulose in alkaline sodium zincate solution, cellulose ethers in aqueous alkali, or cellulose xanthate solutions.  The cellulosic material is precipitated in the usual way, e.g. with dilute acid, and the fabric is washed and dried.  Tentering is necessary and may be effected at any stage and at more than one stage.  The treatment may be repeated.  Fabrics made of viscose rayon, acetate rayon, cotton, nylon, silk and wool are specified. Specifications 573,767 and 573,768 are referred to.

Abstract: 553,370. Electron beam valves and circuits therefor. INTERNATIONAL TELEVISION CORPORATION, Ltd., NAGY, P., and GODDARD, M. J. June 13, 1941, No. 7539. [Classes 39 (i) and 40 (v)] A saw tooth wave generator comprises a beam tube with deflection plates arranged to cause the beam alternately to contact two target electrodes so as to alternately charge and discharge a capacity The capacity may be the deflection plates of a cathode ray oscillograph and a television signal having two periodic signal components established at different amplitude levels may be applied to the deflection plates. One of the target electrodes is charged positively by secondary emission while the other target electrode has associated with it a suppressor electrode and so is charged negatively. Fig. 7 shows a tube construction adapted to provide line and frame scanning potentials, electrodes XF, YF and XL, YL forming duplicate target electrodes with the lines of demarcation between positive and negative charging mutually displaced. The cathode B provides a line source of electrons which are focused by anodes A1, A2 and controlled by plates P1 ... P5, and impinge on either electrode XF or YF to charge output condenser COF. The charging is effected by secondary emission from electrode YF or by the electrons striking plate XF. Electrodes XL, YL similarly charge condenser COL under the control of the line synchronizing pulses. The beam does not reach electrode YF during the line pulses but only during the frame pulses to produce the sawtooth frame potential across condenser COF. Grids SF, SL prevent electrons leaving electrodes XF, XL when the potential is positive, which electrode E screens the electrodes YF, YL. An auxiliary electrode Q collects part of the secondary electrons emitted by electrode YL during synchronizing pulses to charge plate P3 to assist in the deflection of the beam to electrode YF during the longer frame pulses. In a modification, Fig. 6 (not shown), electrodes of different emissive properties are used to obtain appropriate charging rates to give the frame and line scanning. Fig. 4 shows an arrangement modified to show several waves of a signal on an oscillograph in that the deflection plates PI, P3 and the electrode E are connected to the second anode through resistance R2 and to the capacitive potentiometer C1, C2 joining plate P4 to electrodes XV. In this way the electrodes are progressively charged and the plate P3 acquires a negative potential so that the beam reaches the elecrode Y after a time interval depending on the value of variable capacity C2. Specification 553,403 is referred to. Reference has been directed by the Comptroller to Specification 539,661.
