Patent GB-679604-A (GB)
Title: Manufacture of new azo-dyestuffs
IPC: H01J29/39
Filed: 1951-03-16
Abstract: 4 : 41 - Diacetoacetylamino - stilbene - 2 : 21-disulphonic acid is prepared by reacting 4 : 41-diaminostilbene-2 : 21-disulphonic acid with an acetoacylating agent.  An example is given of the reaction using diketene, the product being isolated as its disodium salt.ALSO:The invention comprises dyestuffs of the formula <FORM:0679604/IV (c)/1> where R1 and R2 are each the residue of a diazo component containing a metallizable group in the o-position. These are prepared by coupling 4 : 41 - diacetoacetylaminostilbene - 2 : 21 - disulphonic acid with 2 mols. of a suitable diazo compound, preferably derived from an o-carboxyamine free from further solubilizing groups.  The metallizable group may, however, be hydroxy or carboxymethoxy. Other substituents in the diazo compound may be halogen, alkyl, alkoxy, nitro, acylamino and arylazo; suitable compounds are listed.  The dyestuffs may be used for dyeing and printing animal fibres such as wool, silk and leather and also cotton, linen and regenerated cellulose.  They may be metallized by normal methods in substance, in the dyebath or on the fibre, to give compounds of, e.g., copper, chromium, iron, cobalt or nickel.  The processes of Specifications 455,274 and 619,969 are suitable.  In the examples the diazo derivatives of the following amines are coupled with 4 : 41-diacetoacetylamino - stilbene - 2 : 21 - disulphonic acid:-2 - amino - 5 - benzoylaminobenzoic acid, 2 - amino - 5 - chlorobenzoic acid and 4 - nitro - 2 - aminophenol. A further example is given of the dyeing of cotton, with three alternative coppering treatments.

[Also in Groups XXXV and XXXVIII] The speed of an electric motor 4 is measured by comparing the voltage across the armature 2 of a tachometer generator with the voltage drop across a resistor 6 connected in series with the field 5 of the tachometer across D.C. bus-bars 8, 10. The resistor 6 has a negligible temperature coefficient and is adjusted so that at a desired speed there is zero voltage across the indicating voltmeter 18. As applied to automatic speed control, the voltage at 18 amplified electronically or otherwise, is used to control a regulator 19 in the field circuit of the motor 4, or the throttle of a prime mover may be controlled. Specification 583,728, [Group XXXV], is referred to.

Abstract: 1524443 Washing containers CROWN CORK & SEAL CO Inc 20 Feb 1976 [7 March 1975] 06810/76 Heading B8T In an apparatus for cleaning cans and comprising a coveyer which conveys the cans through a plurality of cleaning zones in which the cans are subjected to spraying by cleaning fluids, means are provided for creating a fog, e.g. by atomizing a liquid, in one or more of the cleaning zones should the spray of cleaning fluid be interrupted due to the conveyer stopping, thereby reducing the oxidation of the cans which would occur if they were allowed to air dry.  In the preferred embodiment, inverted cans 20 are conveyed on a conveyor 24 through a washing zone 10 where they are sprayed with an alkaline washing liquid supplied through nozzles 28 during which process the cans are held in an upright position by means of a holddown conveyor 30. Should the conveyor 24 stop, spraying of the cans ceases and a fog is produced in the washing zone 10, e.g. by spraying an atomized liquid into zone 10 through nozzles 34. The cans proceed past a steam blow-off area 16 provided with fogging nozzles 48, through a rinsing zone 12 which has a second hold-down conveyor 78, past a second steam blow-off area 18 having fogging nozzles 64 and into a deionized rinsing zone 14 where, e.g. water containing no calcium, magnesium and iron is sprayed through nozzles 52 and fog is provided through nozzles 54. As in the case of the washing zone 10, spraying ceases in the zones 14, 16, 18 if the conveyer stops and the respective fogging means are brought automatically into operation. In the case of the rinsing zone 12 no fogging nozzles are necessary as long as the rinsing fluid does not produce an etching or detinning effect.

[Class 18.] A face-powder box according to the parent Specification comprises a casing, a powder drawer to slide in and out of the casing, and means for compressing the powder in the drawer. A drawer 2 to contain powder can be moved by a knob 13 in and out of a casing 1, and it slides on the flat bottom of the casing or in a dovetail groove 4. Outward movement of the drawer may be limited by a stop. The drawer and casing are internally screw-threaded to receive a hollow compresser 5 which can be screwed down to compress the powder into a soft compact. The compresser contains a puff 9 and is closed by a hinged lid 8 which may be formed as a mirror on its inner surface. Before the tray can be pulled out, the compresser is unscrewed until it is disengaged from the drawer, but pins or projections 11, 12 on the compresser and casing respectively limit the extent to which the former is unscrewed. A plate with a dovetail recess and groove may be inserted between the tray and casing so as to support the drawer when pulled out. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement in which stops may limit the outward movement of both the plate and drawer. This subject-matter does not appear in the Specification as accepted.
