Title: Improvements in or relating to metallic structures
IPC: C23C28/00
Filed: 1949-12-02
Abstract: A metallic structure, particularly for an electronic discharge device electrode or a jet engine part, comprises a refractory metal base of tantalum, columbium, molybdenum or tungsten, a hard barrier layer of mixed or alloyed carbides of the base metal and of silicon, titanium or zirconium, and a refractory outer coating of carbon or of one of the metals of the platinum group.  A method of manufacture of a metallic structure as described above comprises the steps of applying a coating of finely divided silica, titania or zirconia to the metal base, sintering the coating, applying a coating of carbon in excess of the stoichiometric amount for reducing the oxide to carbide, firing the structure to at least 1700 DEG C in vacuo or an inert or reducing atmosphere until the carbides are formed, and coating the carbide surface with carbon or one of the metals of the platinum group. The oxide layer and the carbon layers may be applied by dipping, electrophoresis or spraying, using an organic or inorganic binder. The platinum layer is applied by dipping the carbide-coated article into a solution of an organic platinum compound or chloroplatinic acid, withdrawing from the solution and heating for about five minutes at 375 DEG C.  This is repeated at least ten times and a final coating given in a conventional platinum electroplating bath.  The structure is finally fired to about 1500 DEG C in an atmosphere at a pressure of 10-5 m.m. of mercury.

Title: Improvements in and relating to the production of substituted benzoyl halides
IPC: C07C51/60
Filed: 1927-11-18
Abstract: 308,231. Bangham, P. F., Thomas, J., and Scottish Dyes, Ltd. Nov. 18, 1927À Benzoyl halides; benzoylaminoanthraquinones. -Substituted benzoyl halides are made by causing a substituted benzotrihaiide to react with a correspondingly substituted benzoic acid by means of an acidic metallic chloride, such as zinc chloride, in the absence of a solvent. The substituted benzotrihalide may be formed by halogenating the corresponding substituted toluene, and it may be converted into the substituted benzoic acid by treating with boiling milk of lime. The products may be purified by fractional distillation, preferably under reduced pressure, and may be employed for the benzoylation of amino compounds, particularly aminoanthraquinones. In examples, (1) o-chlorbenzotrichloride, obtained by passing chlorine into boiling o-chlortoluene, is heated with o-chlorbenzoic acid and zinc chloride, and (2) a mixture of o- and pchlortoluenes, obtained by chlorinating toluene in the cold in presence of ferric chloride, is converted into a mixture of o- and p-chlorbenzotricblorides by chlorinating at the boiling point, and the latter is heated with a corresponding mixture of o- and p-chlorbenzoic acids, obtained by hydrolysis of the mixture of chlorbenzotrichlorides, in the presence of zinc chloride. In further examples, the mixture of o- and p-chlorbenzoyl-chlorides is employed for acylating 1 : 4- and 1: :5-diaminoanthraquinones, nitrobenzene or o-nitrotoluene being employed as a diluent; the diacyl derivatives are obtained.

Title: Process for the manufacture of synthetic resins, and of varnishes therefrom
IPC: C08F24/00
Filed: 1927-11-22
Abstract: 306,501. Carpmael, A., (1. G. Farbenindustrie Akt.-Ges.).Nov. 22, 1027. Synthetic resins are produced by heating crude solvent naphtha in the presence of a phenol or naphthol with ferric chloride. In an example, #.naphthol is dissolved in crude solvent naphtha which contains phenols and resinifiable constituents such as indene and coumarone but is free from bases. Crystallized ferric chloride and water are added and the mixture stirred for some hours. After dilution with solvent naphtha, xylene or the like and separation of the aqueous liquor, the iron is removed from the solution of the resin by stirring with lime and fullers' earth. A light-coloured resin soluble in linseed, wood and highly viscous stand oils is obtained on removing the solvent. According to a second example a resin is similarly obtained without the addition of a phenol, sufficient being present in the solvent naphtha fraction which is employed. In a third example, the starting material is a solution of crude cresol in crude solvent naphtha freed from bases and phenols. The reaction mav be moderated by cooling. Varnishes are obtained by dissolving the products in the usual solvents.

Title: Improvements in or relating to roll film photographic cameras
IPC: G03B17/42
Filed: 1939-12-08
Abstract: 533,878. Photographic roll-film cameras. KODAK, Ltd. Dec. 8, 1939, No. 31800. Convention date, Dec. 9, 1938. [Class 98 (i)] In a roll-film camera the winding knob of the taken-up spool is locked, when a pre-determined length of film has been wound, by a pivoted lever which is moved into locking position against spring action by a pivoted arm carrying a leaf spring, which spring towards the end of the winding operation is engaged by a pin on a gear rotated by the moving film, and is subsequently flexed to disengage the pin by means of a sliding bar when the shutter release is actuated, whereupon the locking lever and the pivoted arm are spring-urged to inoperative positions in which the pivoted arm is in the path of movement of the sliding bar, so that the shutter release cannot be again operated prior to the winding of an unexposed area of film into position. In the construction shown, the film passes over sharp-toothed sprockets on a shaft to which is clutched a gear 32, which is thus rotated during feeding of the film, the gear 32 driving a gear 3D one rotation of which corresponds to movement of the film from one image area to the next. Towards the end of the feeding movement a pin 54 on the gear 30 snaps into an aperture 53 in a spring blade 52 secured to an arm 44 pivoted on a stud 45, further rotation of the gear 31 turning the arm clockwise so that a lug 50 on it engages one end of a lever 39 pivoted at 40 turning it counterclockwise and causing a tooth 42 formed on the other end to engage a ratchet wheel 43 on the winding-knob spindle, so locking it against further feeding movement. When the shutter-release 60 is depressed, Fig. 8, a cam surface 64 on it engages an inclined surface 65 on a slidably-mounted L-shaped bar 66, which is thus moved to the right, causing the inclined end 72 of a notch formed in an upturned lug 70 on the end of the bar to engage an inclined tongue 73 on the blade 52, which is thus lifted clear of the pin 54. When the knob 60 is, released a spring 47 rocks the lever 39 clockwise, withdrawing the pawl 42 from the ratchet 43 so that a further length of film may be wound. At the same time the arm 44 is turned anticlockwise to the position shown in Fig. 9, in which an extension 74 is opposite the lug 70 on the bar 66, so that movement of the bar to the right, and hence a second actuation of the release is prevented until the film has been wound and the arm 44 turned clockwise as described above. In order to allow free winding of the film when inserting or removing a spool, the gear 32 is driven through a pair of toothed clutch members 35, 36, Fig. 5, the upper of which is movable to disengage the clutch by a spring 76 which is raised by turning a quadrant 75 by means of a knob 80. Specification 491,001 is referred to.
