Patent GB-938955-A (GB)
Title: Improvements in the determination of turbidity in fluids
Inventor: BRIGGS RONALD
IPC: G01N21/53
Filed: 1960-02-18
Abstract: 938,955. Photo-electric turbidometers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 16, 1961 [Feb. 18, 1960], No. 5720/60. Class 40 (3). [Also in Group XX] An arrangement for determining the turbidity of a fluid in which two beams of light, each having an identifying characteristic, are directed into a sample of the fluid in such a way that light from one beam is transmitted directly through the sample to a light detector in the path of the beam, whilst light from the other beam reaches the detector only indirectly by scatter from particles suspended or entrained in the sample, and the two component signals of the detector output corresponding to said identifying characteristics of the light beam are separated and compared to provide a measure of the turbidity of the sample. In the diagrammatic arrangement, Fig. 1, two beams from a light source 18 chopped at different frequencies by dies 19, 20 are passed via lenses 22, 23, to mirrors 24, 25, from the first of which the beam passes through an iris diaphragm 16 and the fluid in the container 11 to the photo-electric cell 14. The beam reflected from the mirror 25 passes through an iris diaphragm 17 through the fluid in the container 11 to a mirror 15 from which it is reflected back into the fluid so that light scattered from the particles reaches the photo-cell 14. The beam passing directly through the container 11 is preferably reduced in intensity by a neutral filter 26 of density 3. The chopper discs 19, 20 have different numbers of alternate opaque and transparent sectors to provide the distinguishing frequencies. The signals from the cell 14, amplified at 26<SP>1</SP>, Fig. 2, are passed to two network chains 27, 29 ... 37 and 28, 30 ... 38, including frequency discriminating filters 29, 30 and amplifying, transmission, rectifier and smoothing circuits. The outputs from the rectifier-smoothing circuits 37, 38 are passed to a double logarithmic bridge circuit 39 connected to a suitably calibrated centre-zone recorder 40. A practical embodiment corresponding to Fig. 1 is shown in Figs. 6, 8 in which light from a lamp 18a mounted in a socket 47 is interrupted by discs 19a, 20a, driven by a motor 21a, the beams passing through adjustable lens assemblies 22a, 23a, to the mirrors 24a, 25a, a neutral filter 26a being included in the assembly 22a. The beam from mirror 24a passes through diaphragm 16a opposite an aperture 69 of the container 11a, Fig. 8, to a photo-cell mounted on support 61 and opposite aperture 67. The second beam passes through diaphragm 17a opposite an aperture 66 and to a mirror 71 closing aperture 68 and effecting reflection of the beam back into the container 1 1a to be scattered by the particles of the fluid. The circuit arrangement according to either of the transmission chains 27 ... 37 and 28 ... 38 is indicated in Figs. 5A ... 5C (not shown), and suitable values for the various components are indicated in the Specification.

Abstract: 339,884. Yates, H. H. April 18, 1929, [Convention date]. Coating yarns.-Apparatus for sizing yarn comprises a size box which can be raised and lowered independently of the remainder of the apparatus, an immersed roller under which the yarn passes, this roller being connected to an upper roller by an endless lattice, and a curved plate over which the yarn passes and against which it is pressed by a roller which reciprocates over the plate. The apparatus shown comprises a frame 5, 6, Fig. 1, in which is mounted the size box 7, wheels 8 on the latter engaging grooves in the frame members 5, and the box being raised or lowered by rack and pinion mechanism. The yarn is passed over drag-rods 11, and over a roller 12. A roller 13 is mounted above the size-box, and carried below this roller on arms 14 is a second roller 15. Running over the two rollers is an endless lattice 16 provided with cross rods 17. The yarn passes under the roller 15, and in case of breakage the broken strand adheres to the lattice and is carried up. Mounted on depending plates 17<a> secured to the cross members 6 is a curved plate 18 and, on each plate 17<a>, a curved guide rail 19. Beyond the plate 18 are squeezing rollers 20, the upper roller being easily detachable; above these rollers is a drying drum 21, from which the yarn passes to a drop roller 22 which moves freely in guides in the frame. The yarn finally passes between rollers 3. A shaft 24 mounted in the frame carries at each end an arm 25, at the upper end of which is mounted a rubber covered roller 26 which presses the yarn against the plate 18. The roller 26 is mounted at each end in a sleeve 27, Fig. 2, which slides over a downturned part of the arm 25. Mounted in the lower part of the sleeve is a sliding block 29 which carries a roller 30. The block 29 is held between springs, and the roller 30 engages the guide rail 19. At the upper end of the guide rail 19 is a guide 33, Fig. 4, having a spring 34 on its inside. Normally the roller 30 runs above the guide rail on the upward stroke of the arm 25, and the roller 26 is not pressed on to the plate 18. On reaching the end of the rail 19, the roller runs down the under side of the guide 33. The spring 34 closes the opening between the two guides, and the roller 30 is forced to travel under the rail 19 on the downward stroke of the arm 25, causing the roller 26 to be pressed on to the plate 18, so squeezing the yarn which passes over the plate. Suitable mechanism is provided for rocking the arm 25.
