Title: Improvements in the production of coloured artificial thread-forming substances and of threads, foils, and the like therefrom
IPC: C08K5/00
Filed: 1950-05-31
Abstract: Artificial thread-forming substances such as cellulose esters and ethers, viscose, superpolyamides, superpolyurethanes, polyesters, polyacrylonitrile, and polyvinyl chloride, are coloured by incorporating in them a pigment consisting of a water-insoluble ester of a leuco vat dyestuff of the anthraquinone series and a monocarboxylic acid having up to 7 carbon atoms. Leuco vat dyestuffs of dibenzanthrone, isodibenzanthrone, dibenzpyrenequinone, indanthrone, flavanthrone, or pyranthrone may be esterified with carboxylic acid anhydrides or halides which do not contain hydrophilic groups, e.g. acetyl anhydride or chloride, or benzoyl chloride.  The esterification may be carried out with the dry leuco compounds in inert solvents or diluents, if desired in presence of acid binding agents, such as alkali acetates, pyridine, or quinoline, but the aqueous solution of an alkali leuco compound may be directly treated with the esterifying agent.  The vat dyestuffs themselves may be reacted with the esterifying agents in the presence of metals having a reducing action such as zinc or aluminium.  By carrying out the latter process in the presence of pyridine or quinoline, the reducing metal may be dispensed with in some cases, e.g. in the case of indanthrone.  The carboxylic acid esters of leuco vat dyestuffs of the anthraquinone series may be added to spinning solutions or masses. The threads or fibres obtained are coloured in a manner fast to washing and light and stable to aqueous alkalies and acids.  The colourings are vat stable so that when a mixed fabric of undyed cotton and viscose rayon or viscose staple fibre, which has been obtained from a spinning solution coloured in the described manner, is subsequently vat dyed, the viscose rayon retains its original colour.  In an example, 2.5 parts by weight of the acetic acid ester of leucodibenzanthrone in a fine powdered form are added to 1,000 parts by weight of viscose containing 75 parts of cellulose.  The viscose is then spun to form threads of a permanent deep red - brown shade.  In another example, the acetic acid ester of the leuco compound of the vat dyestuff resulting from alcoholic potash fusion of bz-1-benzanthronyl-1-amino-anthraquinone is dispersed in a small proportion of a solution of cellulose acetate in presence of a reaction product of ethylene oxide and octyl alcohol.  The pigment preparation is dried and rolled.  It is then stirred into a cellulose acetate spinning solution.  In a similar manner, a pigment preparation of the acetic acid ester of leuco-N,N1-dihydro-1,2,21,11-anthraquinoneazine (leucoindanthrone) may be obtained and may be incorporated in a spinning solution of polyacrylonitrile.  Specifications 24604/08, [Class 2], 337,741, [Class 2 (iii)], and 506,803, are referred to.

Title: Compensating system for a condition-responsive measuring instrument
IPC: G01L19/00
Filed: 1945-05-31
Abstract: 596,993. Pressure gauges; indicating-apparatus. WEINGART, R. I. N. May 31, 1945, No. 13661. Convention date, April 21, 1943. [Classes 106 (ii) and 106 (iv)] In an instrument movement having rotary driving and driven members, incorporating a helix and spring means to maintain contact during return movement, the driving member is rotated by a condition-responsive element influenced by the quantity to be measured and the driven member is displaced axially by a condition-responsive element influenced by a qualifying factor to produce a compensating effect. In a pressure gauge as shown in Fig. 1, the pressure to be measured is communicated to the inside of a capsule 28, exposed externally to atmospheric pressure, and the resultant movement, due to any change of pressure, is transmitted to a pivoted driving arm 21, slotted to engage a helix 12 on a driven indicator shaft 11, which is under the action of a spring 18. Atmospheric pressure acting on a second capsule 38 causes a compensating movement of the indicator by transmitting an axial thrust to the indicator shaft 11 through a pivoted arm 43 and so eliminates the effect of changes in atmospheric pressure from the indication. Similarly, changes in ambient temperature can be eliminated from the indications of a thermometer as shown in Fig. 2, wherein a bulb 64 is exposed to the temperature to be measured and is connected through a capillary tube 63 to a Bourdon tube 60 which supplies a drive to the indicator while a capillary tube 80 is exposed to the ambient temperature and influences a capsule 82 which supplies the compensating drive. Alternative linkwork between capsule and driven shaft, incorporating an extensible driving arm, is described. To compensate for the temperature of an instrument casing alone, a bimetallic strip may be substituted for capillary tube and capsule. As shown in Fig. 5, the helix may be formed on a cylinder 127 keyed to the indicator shaft to allow longitudinal, but not rotative, relative movement, the axial thrust from the driving arm 132 of the compensating device being applied to the cylinder 127. The system may be used to show, in a measuring instrument, the differential in movement of two separate elements responsive to changes in conditions, as, for example, in maintaining equal pressure in two boilers and the system may be used to indicate the sum of two movements. Specifications 557,617, 557,639 and 583,901 are referred to.

Title: Improvements relating to apparatus for the automatic coating of articles
Inventor: WALDRON FELIX WALTER
IPC: B05B13/02
Filed: 1958-04-30
Abstract: <PICT:0910822/III/1> Apparatus for the automatic coating of articles includes a plurality of dispersing devices arranged to produce an adequate dispersion of coating material for the largest article with which the apparatus is intended to be used, and photo-electric control means for detecting the size and position of articles entering the apparatus and for switching on only sufficient of the dispersing devices for coating each article.  As shown, tyres 7 of different sizes 7a, 7b are carried by supports 5 on a conveyer rail 4 through a protective casing 1 in which is a U-shaped cage electrode 3, which can be charged to a high electric potential. Two sets of spray-guns 8a, 8b, 8c and 8d directed into the interior of the cage, are mounted, at heights determined by the levels of the different sizes of tyres, near the exit end of the casing 1, and housings containing lamps 12a, 12b, 12c and corresponding photo-electric cells 13a, 13b, 13c, (not shown) are provided, aligned with openings 11 in advance of the cage 3.  The cell 13a controls, through a relay and solenoid, the guns 8a and 8b, the cell 13b controls gun 8c and the cell 13c controls the gun 8d; the guns are switched off until the light from the lamps is obstructed, thus de-energizing the associated relays, and causing the appropriate guns, corresponding to the size of the tyre, to be switched on in advance of the tyre entering the cage 3.  The control relays preferably include time delay devices which cut out the relays after they have been de-energized for a time equal to that required for the tyre to pass from the lamps and cells to about the centre of the cage, thus prolonging the operation of the spray-guns.
