Abstract: 1,068,848. Web coating apparatus. COTTON SILK AND MAN-MADE FIBRES RESEARCH ASSOCIATION. July 26, 1965 [July 27, 1964], No. 29852/64. Headings D1L. [Also in Division G3] In applying a prescribed amount of a substance, in liquid form or in a liquid, per unit length of a travelling material the material is passed through an applicator system consisting of pad box P guide rollers 4 to 9, mangle bowls 1, 2 and 3 and a liquor control box 12 connected to the pad box P by a weir and circulating pump 15. Substance is supplied to the applicator system, at a rate corresponding to the prescribed rate of application desired, via pipe 14 from pump 29 metering stock liquor and pump 32 supplying basic and auxiliary diluent. Any change in the amount of liquid in the applicator system resulting from a deviation of the actual rate of application of the liquid from the prescribed rate is detected by float 13 and this; through lever 26 and plate 24 effects the pressure in a pneumatic system supplied at 18 so as to vary the pressure in chamber 17 and thus change the loading of bowls 1, 2 and 3 to restore the rate of application to the prescribed rate. In addition to the above control any long term departure of the actual pressure exerted by the bowls from some datum pressure is used to alter some property of the liquid which effects the take up thereof by the material. To this end the pressure in the pneumatic system is caused to operate through damping chamber 40 on a bellows 35 which positions carbon brush 42 along a drum 28 of insulating material, into which, are set two triangular conducting plates 43, 44. The drum is driven by motor 46, set in motion by a periodic switching arrangement in gearbox 50, and depending on the position of brush 42 motor 47 is operated to drive P.I.V. gear 49 which controls the metering pump 32 to adjust, in appropriate manner, the rate at which diluent is fed into the system so as to affect the take-up properties of the substance and restore the pressure at the nip of the bowls to its midvalve. The pump 29 metering stock liquor into the system is driven from the machine drive through P.I.V. gears 30, 31 calibrated respectively in the percentage of finish to be applied to the material and the weight per unit length of material, and the pump 32 delivering diluent is driven through P.I.V. gears 33, 34. Gear 33 is set to give the basic diluent requirement and gear 34 is controlled by motor 47 as explained above to control any auxiliary diluent (positive or negative) which may be required.

[Also in Group XIII] A control device 24 for a steam boiler, (see Group XIII), operates as follows. Feedwater from a pipe 23 enters a port 60 and passes through an orifice 64 in a diaphragm 59 to an outlet 61 and a pipe 25 leading to the boiler. The water flow moves the diaphragm 59 and an attached arm 71 which is connected by a lever 73 to a spindle 74 which is operated to rotate a spindle 86 keyed thereto. The spindle 86, which has an intermediate valve part 86a, is journalled in the bore of a rotatable shaft 88 wh'ch is journalled in a fixed sleeve 92 in a casting 56, the parts 88, 92, 56 having suitable ports as shown in Fig. 5. Rotation of the part 86a permits pressure fluid, e.g. fuel oil, to be delivered by a pump through a pipe 99 and ports 98, 97, 95, and ports 104, 110 or, as shown in Fig. 6, ports 105, 111, to one side of a hydraulic motor comprising two opposed cylinders 112, 113, Fig. 2, each enclosing a piston 114, 115, which are each connected to a crank-pin 90 attached to an arm 89 integral with the shaft 88. The part 86a simultaneously allows oil to escape from the opposite side of the motor through a port 96 and slot 100 in the spindle 86 to a chamber 101 and pipe 109 to the storage tank. Hence rotation of the spindle 86 causes rotation of the shaft 88 which acts to close the port 95, by bringing it into juxtaposition with the part 86a. The spindles 74, 86 remain in their new equilibrium position until a further change occurs in the position of the diaphragm 59. The shaft 88 carries at one end cam plates, one being 120, which act through rollers and mechanical linkages to operate respectively on the stem of a valve in the fuel oil line to the boiler and on a damper in the air supply line.
