Abstract

273,230. Peschl, F. A. June 22, 1926, [Convention date]. Indicating - apparatus. - The humidity of the paper web at any suitable point in its passage through a paper-making machine is indicated by providing electric contacts adapted to engage the web, such contacts being mounted in spaced relation, and insulated from each other, and included in an electric circuit containing a galvonometer or like measuring instrument. As shown the device is applied to a Fourdrinier machine for indicating the humidity of the web passing from the press rolls 5 to the wet drying rolls 7, and comprises a number of copper &c. plates 8<a>, 8b arranged within a block of insulating material 12, the plates being preferably connected electrically in two series with the slates of one series alternating with those of the other series. The block 12, which is mounted so as to have pivotal movement in. the direction of the travel of the web, is supported upon guides 26, so as to be capable of lateral and vertical adjustment with respect to the web. A device for compensating for variation in the acidity of the stock is preferably provided, and may comprise a resistance consisting of plates 45<a>, 45b immersed in stock contained in a tank 42a, such resistance being .arranged in a branch circuit, and the branch may, as shown in Fig. 7, include a coil 49 incorporated in the measuring instrument and wound in a direction opposite to that of the actuating coil b of the instrument. Alternatively a manually adjustable resistance may be provided, such resistance being arranged either in series with or parallel to the resistance of the web.
