Filed: 1923-03-08
Abstract: 216,598. Lord, G. S. March 8, 1923. Hank type; mangling and wringing apparatus.. - Alter the hanks have been treated with liquid, the frame 7 on which they are supported is lifted from the vat by means of tackle on an overhead carriage 8, Fig. 4, and then placed in position above a squeezing-frame 28; or the latter may be mounted on rails as shown and run into position below the frame. The squeezing-frame carries pairs of rollers 29, 30, Fig. 4, corresponding in position with the rollers 17 at the lower part of the frame 7 so that each of the latter rollers rest snugly between the pairs of squeezing- rollers; the latter are rotated by hand or otherwise, and for this purpose are geared together by means of a chain 31 and sprocket wheels 33 which may drive the rollers 29 through ratchet-mechanism. The squeezing-rollers may be of the type described in Specification 167,868. During the squeezing operation the member 7<b> carrying the lower rollers 17 of the frame may be locked in position. The invention is described in connection with a construction of treatment apparatus in which the frame 7, Figs. 1, 2, 4, carrying the pairs of rollers 16, 17 for supporting the tanks, is raised and lowered in the vat while at the same time the rollers themselves are rotated; thus. the frame 7 is carried by yokes 15<a> connected by bars 15 which rest on eccentric pins 12 carried by gearing on opposite sides of the vat; as the frame rises, so a pinion 25 carried by the frame is rotated by a rack 26 fixed to the vat, and drives through ratchet-gearing the sprocket wheel 22 of a chain 21 which serves to drive, also through ratchet-gearing, the upper rollers 16; by this construction these rollers are rotated as the frame rises, but the gearing may be modified in such a manner that the rollers are rotated during only a portion of the rise of the frame or during both its rising and falling movements. The member 7b carrying the lower rollers 17 is mounted in slots and engages a stop 7d as the frame falls so that the tension on the hanks is released, allowing the hanks to float in the liquid.

Abstract: 1,089,672. Photo-electric measurement of stain intensity. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 18, 1965 [Feb. 19, 1964], No. 6898/64. Heading G1A. Apparatus for the measurement of the intensity of stains in a filter medium, produced by particulate or gaseous pollutants in air &c., includes means for repetitively scanning stained and unstained portions of the filter using a beam of light which is reflected off the filter and detected to obtain an indication of the alternating component of the intensity of the reflected beam representative of the intensity of the stains. The stains, obtained by drawing polluted air through a number of nozzles arranged symmetrically on a circle on the filter paper Fig. 1 (not shown) are substantially equal in intensity. The paper is rotated in a holder 3 (Fig. 2) about its centre. Light from a source 6 is focused via a half-silvered mirror 8 on to the edge of the circle defining the positions of the stains, and reflected back through the mirror 8 to a photo-cell 9. The A. C. component of the signal is amplified and indicated, such that the magnitude of the indication increases with the intensity of staining. The frequency of the A. C. signal depends on the speed of rotation of the holder 3 and on the number of stains on the filter. To improve the sensitivity of the apparatus against the effects of surface imperfections in the filter, the amplifier may include a tuned circuit tuned to the modulation frequency. In alternative arrangements, the filter may be moved in an oscillatory manner along a line e. g. by means of a mechanical tuning fork drive &c. or the beam of light can be moved over a filter to provide the scan.
