Title: Improvements in or relating to fluid metering apparatus
IPC: G01N15/12
Filed: 1957-09-03
Abstract: 865,070. Sampling liquids. COULTER, W. H., and COULTER, J. R. Sept. 3, 1957, No. 7193/60. Divided out of 865,069. Class 106(5) A measured quantity of liquid is drawn through a small hole in a container, each particle interrupting an electric circuit the interruptions being counted. In the arrangement shown the liquid 58 is drawn through a small aperture 47 into a further container 41. As each particle passes through the aperture it interrupts the conductive path between electrodes 50, 54. The liquid is drawn in by the mercury siphon arrangement comprising reservoir 26 and capillary tubes 20, 21, 28. Initially cock 13 is open and the mercury is drawn off into the reservoir by suction applied at tube 12. The cock is then closed and the mercury tends to equalise the level in the two branches 20, 21 drawing further liquid 58 through aperture 47. When the mercury reaches contact 32 in a branch 28 of the capillary tube it sets the counter mechanism 39 which is then able to count each passage of a particle through aperture 47. Counting continues until the mercury reaches contact 31 when the counter is switched off. The volume of the capillary bore between contacts 31 and 32 represent the measured quantity of the sample liquid drawn into tube 47. The configuration of the branch (shown in plan in Fig. 2) ensures that the suction head remains substantially constant throughout the measuring operation.

Abstract: 1,093,596. Electro-photographic processes. FARBENFABRIKEN BAYER A. G. Feb. 19, 1965 [Feb.21, 1964], No.7328/65. Heading G2H. In contact printing by the reflex method, a charged photo-conductive layer is masked, during exposure, by a half-tone screen superimposed thereon, by contact on optical-projection, so that the layer retains the charge pattern, due to the screen, only where the masking is not made ineffective by light diffusely reflected from the light-coloured parts of the opaque original. The photo-conductive surface of the light transmitting copy material is placed in contact with the original or with a thin insulating foil covering the original, and a lens system may be used to project an image of a half-tone screen on to the photo-conductive layer Fig. 1 (not shown). The screen may, alternatively, be integral with the copy material. A half-tone screen may be printed in ink on transparent conductive paper and the printed side coated with a dispersion of zinc oxide in a silicone resin binder. After charging and reflex printing, the photo-conductive surface is developed with a black fusible powder applied by means of a magnetic brush. The developed image is electrostatically transferred to ordinary paper and fixed thereon. Alternatively, a photographic film base having a silver half-tone screen formed in a gelatine layer has the latter vapour coated with a semi-transparent layer of aluminium, which is overcoated with a photo-conductive layer. After charging and reflex printing, the latent electrostatic image is transferred to a layer of polythene on a paper support, on passing between a pair of rollers connected to a source of electrical potential. The transferred image is developed by a charged aerosol of a dye solution.

Title: Improvements in machines for cutting sugar or the like
IPC: C13B45/00
Filed: 1921-03-09
Abstract: 159,899. Imray, O. Y., (Soc. Anon. Raffinerie Tirlemontoise). March 9, 1921. Sugar cutters. - A feeding-device for a sugar-cutting machine consists of two portions, of which one brings the sugar up to the cutters and the second moves it while it is being cut and regulates the size of the cut pieces. For this purpose, the plates or bars n of sugar are carried on frames c formed with racks d adapted to engage with gear-wheels e, p driven by ratchet-wheels g, q and pawls h, r operated from the main shaft of the machine. The teeth of the ratchet-wheel g are uniform and under its action the sugar moves on until the rack d engages with the wheel p. Meanwhile the pawl r has been moving to and fro on a tooth 1 of the wheel q of such size that the wheel is not advanced. Under the action of the rack d the wheel g moves on and the pawl r engages with a series of teeth 2 - - 5 and moves the sugar up to the knives m, the wheel g overrunning the pawl h. A series of teeth 6 - - 27 then moves the sugar on in steps corresponding to the thicknesses of the cubes required, the first cube being preferably the largest. The sugar is then withdrawn from the knives by teeth 28 to 30, and the cycle recommences. A band brake v prevents the wheel q from being moved on accidentally, and means are described for throwing either or both of the pawls h, r out of action. In a modification the ratchet wheel g is replaced by a continuously-driven wheel, appropriate alterations in the wheel q being described. In order. to keep the bars of sugar in uniform relation with the plates c they pass under discs B, Fig. 5, loose on a bar A extending across the machine and held down by their weight or by springs, so that the sugar-blocks are held against the rear side of the frames.

Title: Manufacture of poly-cyclic aromatic aldehydes and carboxylic acids
IPC: C07C51/34
Filed: 1936-03-14
Abstract: Polycyclic aromatic aldehydes and carboxylic acids are made by treating an aromatic compound containing at least four condensed nuclei with ozonized oxygen, and decomposing the ozonide thus obtained, which need not be isolated.  As aromatic compounds may be used polycyclic hydrocarbons, cyclic ketones or quinones, or their substitution products, such as their alkyl, halogen, nitro, aryl, or carboxyl substitution products.  In examples: (1) fluoranthene is treated with ozoniferous air or oxygen to give fluorenone-1-aldehyde and fluorenone-1-carboxylic acid; (2) benzanthrone gives anthraquinone-1-carboxylic acid and anthraquinone-1-aldehyde, the bisulphite solution of which dyes wool carmin-red shades, the bath remaining colourless; and (3) pyrene gives phenanthrene-4-aldehyde-5-carboxylic acid (which gives phenanthrene on dry distillation with soda lime), or with excess ozone diphenyl-2 : 2<1>-6 : 6<1> tetracarboxylic acid, which may also be obtained by alkaline oxidation of phenanthrene 4-aldehyde-5-carboxylic acid with permanganate.  The solvent used in the examples is glacial acetic acid, though it may be replaced by carbon tetrachloride or nitrobenzene.  1-Hydroxy-2-phenylazopyrene and 1-hydroxypyrene are obtained by heating phenanthrene-4-aldehyde-5-carboxylic acid with phenylhydrazine or hydrazine respectively in glacial acetic acid. Phenanthrenequinone - 4 : 5 - dicarboxylic acid is obtained by oxidation of phenanthrene-4-aldehyde-5-carboxylic acid with chromic acid.
