Title: Improvements in or relating to means for controlling and regulating the pulp feed topaper-making machines, mixing vats and the like
IPC: D21F1/06
Filed: 1937-09-21
Abstract: 492,926. Electric control and signaling systems. PALM, H. Sept. 21, 1937, No. 25558. [Class 40 (i)] [Also in Group VIII] In apparatus for controlling and regulating the operation of paper-making machinery in which a stream of pulp A flowing over an overflow B into a channel C is divided by a movable slide D into two parts cl and c<2> one of which flows on to the paper-machine while the other returns to the mixing vat, the slide D is operated by a motor E, and a remotelysituated indicating device, e.g. a pointer d<3> and scale F<2>, is operatively connected with the motor E so as to be displaceable simultaneously and proportionately to the displacement of the slide D. The indicating device is operated by an electric motor E<2> electrically connected with motor E for synchronous motion. Both motors are controlled by a starting, stopping and reversing switch G. Two pulp streams may be controlled thus, and a definite proportion of each forwarded to one paper-machine or to a mixing vat, or one stream may be gradually cut off from the paper-machine while a second is gradually and proportionally cut in, e.g. to change the colour of the paper during production. The two controlling slides may be operated by a common motor, and the corresponding indicators by separate motors or by a common motor. The slide-operating motors may be fitted with circuit-breakers to stop the motor when the slide has reached a desired position. A similar device may control the supply of diluting water to the pulp, and remote control devices for other operations of the machine, e.g. operating speed, quantity of drying steam, and power supply may be combined at the same remote control station. The switches may be coupled to change several factors in proportion, e.g. when changing the weight of the paper, or the operating speed, all other factors remaining the same.

Title: Improvements in the colouring of textile materials
Inventor: FRANCE EDWARD
Filed: 1961-07-20
Abstract: Fibres made from acetone-soluble copolymers of acrylonitrile with vinylidene chloride are dyed by allowing them to take up a dye or compound convertible to a dye from an aqueous liquid medium which is at a temperature above 100 DEG C., preferably at 105-115 DEG C. This may be achieved by immersing the fibres in an aqueous liquid containing the dye or compound convertible to a dye and heating in a pressure vessel; alternatively the dye may be applied by padding, printing or otherwise mechanically impregnating the fibres with an aqueous preparation and then steaming with saturated steam at pressures of 17.5-25 p.s.i. absolute.  Suitable dyestuffs are disperse dyes of the azo, aminoanthraquinone and nitrodiarylamine series and water-soluble 1:2-metallised azo or azo-methine dyes which contain the groupings o, o\sv -dihydroxyazo or 0, o\sv -dihydroxyazomethine and which are free of sulphonic acid groups. Suitable compounds which are convertible into dyes are enolic azo coupling components and diazotisable amines. Specified coupling components are the aryl amides of p  2:3-hydroxynaphthoic acid, 3-hydroxydiphenylene-oxide-2-carboxylic acid and 2-hydroxy-carbazole-3-carboxylic acid and diacetoacetyl-o-tolidine. Diazotisable amines may be applied in the absence of a coupling component and subsequently diazotised and coupled on the fibre in a separate bath.  The preferred copolymers to be dyed contain 44-54% acrylonitrile, the remainder being vinylidene chloride.  The fibres may have been stretched and annealed as described in Specifications 674, 323, 709, 995 and 898, 734.  Examples are given.
