Title: Manufacture of azo-dyestuffs
IPC: C09B29/30
Filed: 1927-07-29
Abstract: 275,258. I. G. Farbenindustrie Akt.- Ges. July 29, 1926, [Convention date]. Samples furnished. Aminonaphthol derivatives; azo dyes. - Azo dyes are made by coupling diazo compounds with aminonaphthol derivatives of the general formula HO-R-NXY, where R is a naphthalene nucleus, which may contain substituents, e.g. sulpho groups, X is hydrogen, alkyl, aryl, or aralkyl, and Y is an esterified carboxyl group, e. g. -COOC2H5. Such compounds are obtained hy the action of a halogenated acid ester on an aminonaphthol, advantageously in the presence of an acid-binding agent. In examples, (1) diazotized p-aminomethylacetanilide is coupled with the product obtained by the action of chloroformic ethyl ester on the sodium salt of 2 : 8 : 6- aminonaphtholsulphonic acid, and (2) diazotized m-xylidine is coupled with the product obtained by the action of chloroformic ethyl ester on the sodium salt of H-acid; the product dyes wool in an even bluish-red tint, fast to light. The products obtained by the action of chlorformic ester on 2-ethylamino-8-naphthol-6-sulphonic acid and 2-amino-8-naphthol are also specified as coupling components. If anthranilic acid or an o-aminophenol has been used as diazo component, the dye stuffs may be after-chromed in known manner. The aminonaphthol derivatives may also be used for the manufacture of disazo and polyazo dyes. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of coupling components of the above formula in which Y is the residue of any carboxylic acid ester, e.g.- CH2-COOC2H5, and states that when products such as that from chloracetic ester and 1: 8- aminonaphthol-4-sulphonic acid are used the coupling may occur, according to the conditions, in o-position to the amino group or to the oxy group; in the latter case the dyeings may be afterchromed. o-Aminonaphthols are also specified as diazo components suitable for producing dyeings adapted to be after-chromed. This subjectmatter does not appear in the Specification as accepted.

Title: Method and means for determining the depth of water on the surface of another liquid heavier than water
IPC: G01F23/00
Filed: 1927-07-29
Abstract: 299,824. Jelffs, W. F. July 29, 1927. Dipping-rods.-The depth of water on the surface of a heavier liquid, e.g. creosote, is determined by a water-indicating paper which is protected from contact with the water layer while being moved through it. A vertical rod 11, mounted in the base member 9 carries the water-indicating paper, and a cylinder 1, closed at the top, is adapted to be lowered over it. The cylinder is guided through a top plate 8, and carries a lower guide plate 4 sliding over rods 5. The device is lowered through the water layer in the position shown, so that the paper is protected by the air trapped in the cylinder 1, until it reaches a position partly in both liquids. The cylinder 1 is then raised, so that the depth of water is indicated on the paper, and the cylinder is then lowered again, so that the paper is protected while being drawn upwards through the water.

Title: Improvements in, or relating to, pistols for stunning animals preparatory to slaughtering
IPC: A22B3/02
Filed: 1944-10-19
Abstract: 614,907. Slaughtering-pistols. ACCLES & SHELVOKE Ltd., and ARROWSMITH, J. B. Oct. 19, 1944, No. 20220. Addition to 581,409. [Class 119] [Also in Group XXXII] The invention of the parent Specification is modified by replacing the leaf-springs acting on the breech-block, extractor and pawl by a spring 41, Fig. 7, comprising three prongs 44, 45 and 46 which bear respectively against the breech-block 10, the extractor 11, and the extractor pawl 15, the attachment eye 43 being offset so that the pistol cannot be assembled if the spring is inverted on the grip. Correct alignment is maintained by the heel of the prong 46 abutting against the grip portion, and the coils 47 are adapted to bear against the underside of the barrel, so that upward movement of the prong 45 does not displace the other two. The breech-block is maintained in its forward (firing) or rear (loading) position by the prong 44 bearing against the surfaces 21 and 22, Fig. 7. The attachment screw, 42, has a head which closely abuts the underside of the barrel to prevent accidental loosening. To assemble the pistol, bolt holes in the grip and barrel portions are brought into register and bolts 3 and 4 passed through (Fig. 1) and held by nuts 5. A locking plate 6 is then fitted to the nuts in place of the bent wire used in the parent invention. The plate has holes to accommodate the ends of members 13, 18 and 19 and to it is pivoted a lever 49, with notches to engage peripheral grooves in the above members and with indentations 57 to engage corresponding recesses in the plate. To remove the latter it is therefore necessary first to pivot the lever 49 downwards by levering with a suitable tool against the ear 58.

Title: Improvements relating to hydraulic turbo couplings
IPC: F16D33/12
Filed: 1956-07-02
Abstract: 828,158. Hydrokinetic couplings. SINCLAIR, H. June 19, 1957 [July 2, 1956], No. 20453/56. Class 69 (2). An hydraulic turbo coupling having hydraulically controlled quick-emptying valves 6 is provided with means for reducing the time lag in the opening of the valves when the coupling is operating at low speed. Each valve comprises a disc 16 which seats to close communication between an orifice 8 open to the working chamber of the coupling and an outlet port 28, being urged to the seating position by pressure in a space 32 which is provided with a leak-off nozzle 19 and centrifugally controlled nozzles 21. During operation of the coupling liquid continually drains from the working chamber through restricted ports 30 in the valves 6. An adjustable scoop tube 34 supplies liquid from a rotating reservoir 33 to the working chamber via a cooler and also supplies liquid through a feed tube 41 to the valve space 32. In the operation of the coupling at full speed, when the scoop tube is withdrawn to cut off the supply of liquid, the space 32 drains through the leak-off nozzle 19 until the liquid in the working chamber is able to unseat the disc and obtain substantially unrestricted communication with the reservoir 33. At, say, three quarters of the full coupling speed, one of the centrifugally controlled nozzles 21 is arranged to open so that liquid can exhaust through this nozzle and nozzle 19. This counteracts the effect of the reduced centrifugal force of the liquid in tube 41 and gives the same time lag in the unseating of the disc as at full speed. At, say, half speed the other nozzle 21 is arranged to open. A greater number of nozzles 21 opening at different speeds can be employed to equalize the time lag at a greater number of speeds. Each feed tube 41 may supply a plurality of valves 6, or a feed tube may be associated with each valve and the spaces 32 of a group of valves be interconnected so that one group of control nozzles 21 controls the group. Instead of using nozzles 21 that are either fully open or fully closed the nozzles may open progressively. In addition a centrifugal control nozzle may be thermostatically regulated to decrease the leakoff area with increased temperature of the working liquid.

Title: Improved Method and Apparatus for Spraying or Disseminating Liquids.
Inventor: DUNN CLEMENT EDWARD
IPC: B05B7/30
Filed: 1918-12-11
Abstract: 135,965. Dunn, C. E. Dec. 11, 1918. Air-pressure sprayers.-Liquids such as paint &c. are projected by first agitating a body of the liquid with compressed air, and then charging the air with such liquid by causing the liquid to be drawn in an annularly-formed spray into a rapidly moving current of the air, producing a mixture, which is compressed into a compact stream and then discharged. A reservoir 2 containing the liquid is provided with air-supply pipes 7, 19 controlled by valves 8, 9, 21, and exit pipes 23, 16 controlled by valves 24, 18, from which liquid and air respectively pass. In normal operation, the valve 21 is closed and the others open, and compressed air passes up through the pipe 4 and rose 5 to agitate the liquid. On opening the valve 31, liquid passes up the tube 23 past the ball valve 25, where it is atomized by compressed air from the chamber 2 passing through the closed chamber 17. The annular spray formed at 25 is compressed into a compact stream by means of a cone 27, and passes through the hose in the spraying-nozzle 32. Should the hose 29 burst, the ball valve 26 will be seated in the cone 27 and thus prevent escape of the liquid.

Title: Improvements in continuously operating closed kneading machines for margarine and other edible fatty substances
IPC: B01F5/06
Filed: 1933-07-24
Abstract: 412,779. Kneading-machines, GERSTENBERG, A., 12, Falkonergaardsvej, Frederiksberg, near Copenhagen. July 24, 1933, No. 20800. Convention date, Aug. 16, 1932. [Class 86.] A method of preventing decolouring of margarine in a continuous kneading process consists in subjecting the margarine to a vacuum during the kneading operation to withdraw air from the margarine. Apparatus for carrying out the method comprises a casing o with supply opening a and kneader members b, c, e, l mounted on a common shaft. The member b feeds the margarine so as to fill entirely the passage areas of the kneader members. The margarine moves into a chamber d and is engaged by the member e which forces it through openings f, in one or more resistance plates a. The plates a offers such resistance that the margarine will entirely fill the chamber d to compress the air bubbles which burst and are drawn away by vacuum apparatus attached to a vent j. The margarine may receive further similar treatment by a member l in a chamber with a vent opening n. The members e, l, the latter of which may be omitted are of such a high capacity as to convey the margarine past openings g, n without allowing it to pass into the openings. Several vent openings may be provided with unequally reduced pressures so that the members e, l, will have the same back pressure to overcome. The Specification as open to inspection under Sect. 91 comprises also modified apparatus Fig. 2 (Cancelled) in which the margarine is fed between twin-rollers v to a kneader b with vacuum apparatus connected to a vent j. In a further modification, Fig. 4 (Cancelled), rollers v are replaced by twin worms s and the vent j is placed in front of the supply opening r. This subject-matter does not appear in the Specification as accepted.
