Patent GB-659944-A (GB)
Title: Improvements in or relating to bituminous material
Filed: 1949-05-02
Abstract: In order to prevent the stripping of bituminous materials, e.g. an asphaltic bitumen or a bitumen cut-back, from stony aggregates, particularly those of an acidic nature, the naphthenic acids in the bitumen are converted into a non-acidic substance or to so weakly an acidic substance that it will not react with amines, and incorporating into the material prior to, simultaneously with, or after the conversion, a cation-active amine.  The conversion may be effected by means of an inorganic or organic base in amount just sufficient to neutralize the naphthenic acids, e.g. by heating with an alcoholic solution of an alkali metal hydroxide or with a low molecular weight mono- or polyamine; in the latter case the bitumen is subsequently heated to convert the amine salts into naphthenic acid amides.  If a polyamine be used, it is employed in equimolecular proportion to the naphthenic acids so that amine salts with free amino groups possessing surface-active properties are produced. Alternatively an amino-alcohol, e.g. ethanolamine, may be used in equimolecular proportions to produce an amide with a free hydroxyl group to increase the adhesive power to basic aggregates.  If a volatile amine be used, the mix is preferably heated first only to 60-100 DEG  C. for 1/2 -3 hours to promote the salt formation and then to 100-150 DEG  C. for 1-3 hours to effect conversion into the amide; alternatively, heating may be effected in a closed vessel. The cation-active amine may be an oleophilic high-molecular weight amine such as octadecylamine, or a product obtained by chlorinating paraffin wax and reacting the product with ammonia. Suitable amines for treating the bitumen are propylamine, di-ethylamine, ethylene diamine, propylene diamine, hexamethylene diamine, di-ethylene triamine, tri-ethylene tetramine, and tetra-ethylene pentamine.

Title: Process for dyeing cellulose acetate rayon
IPC: C09B1/34
Filed: 1944-06-19
Abstract: Cellulose esters, dyeing.-Cellulose acetate artificial silk is dyed in blue shades by treating it with an aqueous solution containing a substance of the general formula <FORM:0579017/IV/1> (in which Y is an alkali metal or ammonium and in which the pendant phenyl nucleus bears a saturated hydrocarbon substituent of from 3 to 6 carbon atoms, which may be continuous, branched or cyclic, or may be condensed with the phenyl nucleus to constitute a tetrahydronaphthyl residue), and containing also a salt of an alkali metal or ammonium, particularly a sodium salt of an inorganic acid, e.g. sodium chloride or sulphate.  The process, which is characterized by a high degree of exhaustion of the dye bath, is particularly suitable for dyeing in conditions wherein dilute aqueous solutions of the dyestuff are used, e.g. in dyeing cellulose acetate fabric in the winch or cellulose acetate yarn in the beck.  In an example, cellulose acetate fabric is immersed in a bath at 30 DEG  C. containing an aqueous solution of sodium 1-amino-4-p-n-butylanilinoanthraquinone - 2 - sulphonate and sodium chloride, the temperature is raised to 85 DEG  C. and the fabric is subsequently rinsed and dried.  The dyestuff may be replaced by sodium 1-amino-4-p-isopropyl-, p-tert.-butyl-, o- or m-n-butyl-, p-isoamyl- or p-cyclohexylanilinoanthraquinone - 2 - sulphonate or sodium 1 - amino - 4 - ar - tetrahydro - a  - or b  - naphthyl - aminoanthraquinone - 2 - sulphonate.  Other specified substituents in the nucleus of the anilino group are n-propyl, isobutyl, n- and isoamyl and n-hexyl.  Dyes of the general formula given above are obtainable by the action of a suitable aromatic amine on a 1-chloro- or 1-bromo-4-aminoanthraquinone carrying in the 3-position a group -SO3Y as defined above or a halogen atom which, subsequently to the condensation, is replaced by -SO3Y by treatment with a sulphite of an alkali metal or ammonium. Specifications 228,557, [Class 2 (iii)], and 446,819 are referred to.

Abstract: 253,870. Bragg, C. S., and Kliesrath, V. W. June 16,1925, [Convention date]. Pneumatic relays.-In engines the suction of which is utilized to operate a suction-actuated device, " stalling " of the engine and delay in re-starting due to weakening of the mixture by air exhausted from the device are prevented by passing the air through a surface carburettor before its admission to the induction pipe or manifold, the carburettor comprising a device for collecting liquid particles of fuel from the mixture passing through the induction pipe or manifold and holding it in a capillary retaining means. The brake lever 72, Fig. 1, of a motor vehicle is connected by a link to a hollow rod 5, Fig. 2, provided with an air-inlet aperture 5a, and secured to a double-acting piston 3 in the cylin. der 1 of the brake actuator, Valve mechanism 6 is located in the hub of the piston, and comprises valves 40 - - 43, of which 41, 42 control the suction ports and 40, 43 the air-inlet ports, the valves being all narmally pressed towards their seats by yielding cushions 50 and operated by collars on a tube 20 connected to a spring-loaded brake-operating pedal 74. A flexible suctiontransmitting pipe 26 is connected at one end to the tube 20, and at the other end to a surface carburettor 61<1> opening into the intake manifold 61 between the throttle valve 69 and the cylinders. The tube 20 communicates with a suction chamber 17 in the piston hub, which also contains an inlet chamber 18 in communication with the atmosphere through the tube 20 and aperture 5<c>. The tube 20 has a partition 21 separating the inlet passage to chamber 18 from the suction passage to chamber 17. Movement of the tube 20 to the left, Fig. 2, will open the valve 43 and admit air to the rear of the piston, the other side of which will be subjected to suction through the pipe 26, tube 20 and valve 41; movement of the tube in the opposite direction will reverse the connections. The surface carburettor 61<1> preferably comprises a receptacle 61<a> attached, to the pipe 26 and connected to the manifold 61 by a pipe 61<b>, so as to trap liquid particles of fuel deposited in the manifold. The receptacle is filled with capillary material, e.g. finewires, or fibrous material such as asbestos wool, which may be in the form of a coiled wick 61<c>.

Abstract: 549,890. Electron image dissectors ; television. STANDARD TELEPHONES & CABLES, Ltd. Sept. 19, 1941, No. 12064. Convention date, Sept. 24, 1940. [Classes 39 (i) and 40 (iii)] In an electron camera of the image dissector type used to scan a motion-picture film in successive transverse lines-the film movement providing the " frame " scanning movement - the effect of an irregularity on the photo-sensitive screen is reduced by (i) distorting an elemental strip of the picture or (ii) moving the optical strip image about the screen. (i) By means of a light 12, Fig. 1, and an optical system 13, 14 a portion of the film 10 which is moving over the rollers 40, 41 is focused on a diaphragm 15 with slit 16 ; a further convex lens 17 and concave cylinder 18 is used to produce a wide distorted picture of this slit on the photo sensitive screen 19 the emission from which is scanned over a slit 21 or square aperture in the dissector tube 22. The electron image is received on the output electrode 23, which may be connected to the signal resistance 24 directly or through an electron multiplier. The lenses 17, 18 may be placed next to the lens 14 the diaphragm 15 being omitted. (ii) The optical image of the slit 16 is moved up and down the screen by a pair of prisms 42, 43, Fig. 2, rotating in opposite directions or by a glass plate with plane parallel faces and tilted about a horizontal axis. In this form also the diaphragm 15 may be dispensed with. In addition to the electromagnetic means 28 for scanning the electron optical picture across the slit 21, Fig. 1, or aperture 46, Fig. 2, in this second arrangement a further focusing device is used consisting of an electromagnet 44, which acts in synchronism with the movement of the prisms 42, 43 or plane glass plate to bring the electron optical line emission as it moves about the screen in all cases to the level of aperture 46 as it arrives at the dissector tube. The Specification as open to inspection under Sect. 91 states that the invention is applicable to iconoscopes. This subject-matter does not appear in the Specification as accepted.
