Title: Improvements in or relating to ballistic particle size discriminators
IPC: B07B13/10
Filed: 1958-07-15
Abstract: 861,285. Spraying apparatus. McGINN, J. H. July 15, 1958, No. 22668/58. Class 69 (3). [Also in Group II] Apparatus for the separation of particles in gaseous suspension, e.g. aerosols of liquid or solid particles, either for sampling or collection purposes, comprises a chamber 2 with a small inlet aperture 6 towards which a stream of gas-borne particles are directed. The aperture is considerably smaller than the cross-section of the stream so that all particles of the same size projected through the aperture have the same velocity. The chamber is closed and provides a still region of gas, and the particles are slowed down to zero velocity by gas friction alone and fall on to a surface 16. The distance traversed by the particles within the chamber is approximately linearly proportional to their diameters. Fig. 2 shows a sampling apparatus in which a heat insulated cylindrical separation chamber 48 has a particle inlet aperture 52 and apertured baffles 54 to damp out turbulence; a collection surface 56 and a control shutter 60 are provided. The particles are projected from a nozzle 30 having its outlet end contained within a sealed cylindrical chamber 18 in which a slight negative pressure is maintained by a vacuum pump connected to a tube 42. The surface 56 may comprise a sheet of paper or glass provided with a sticky coating. Alternatively, the surface may be replaced by a plane of light, the passage of particles across which may be counted at various parts of its length by dispersion of ligh to one or more photo-cells. The collecting surface may also comprise a cylindrical surface driven about its axis and arranged longitudinally of the chamber. The sampling apparatus of Fig. 6 can be used in any position, and has a collecting chamber in which an adjustable transverse uniform gas stream flows to provide an effective deposition of the particles on to a filter paper 190 or the like. Porous walls 160, 162 are located in the chamber, and a gas inlet is located on one side and a gas outlet on the other.

Title: Improvements in or relating to the manufacture of annular metal rings and part annular metal components
Inventor: NORRIS DOUGLAS CAMPBELL
IPC: B21D53/16
Filed: 1969-05-05
Abstract: 1280331 Making rings; winding strip as edge; shearing D C NORRIS & CO Ltd 22 July 1970 [5 May 1969] 22795/69 Headings B3A B3E and B3W Annular metal rings and part-annular components are made by winding a strip of metal S edgewise into a close-packed helical coil C, profiling the strip to compensate for the distortion which takes place during winding, and cutting the coil C to separate the individual turns. A tailstock, comprising a die block 4, a pressure plate 5 and a guide 7, is moved near a shoulder 10 and the leading edge of the strip passed through rollers 8 and guide 7 into the entry zone 121 of the die 4. The leading edge is attached to the shoulder 10 by means of a device 11 after which the die is urged into contact with the shoulder by an hydraulic accumulator 14. A mandrel 3 is then rotated so that the leading edge of the strip is drawn in from the entry zone 121 into the sizing zone 122 where the strip contacts the shoulder 10 and is compressed to give a taper which compensates for the taper produced as the strip is wound round the mandrel. Continued rotation of the mandrel completes the first turn of the coil which leaves the channel at 124 to ride over the fresh strip continuously entering the zone 122. As the number of turns increases, the die block 4, pressure plate 5 and guide 7 are forced away from the shoulder against the hydraulic loading. On reaching the desired length of coil, the mandrel is removed and the coil is cut longitudinally by a rotary saw. The coil is thus divided into separate rings, the free ends of each ring being welded or keyed together. In another embodiment the surface 12 of the die block 4 is not bounded by a radially outer edge so that the profiling takes place at the entry to the sizing zone 122 where the strip is drawn across a shallow raised edge. Shearing.-The coil is loosened and has a notch made in each turn so that on advancing the coil lengthwise, each notch passes between sensor tubes 211 and 212 and allows an air jet to pass between the sensor tubes to operate a guillotine.

Title: Manufacture of compounds of the morpholine series
IPC: C07D265/30
Filed: 1927-09-01
Abstract: 298,336. Imperial Chemical Industries, Ltd., Payman, J. B., and Piggott, H. A. Sept. 1, 1927. Morpholine and its derivatives are prepared by condensing alkylene or aralkylene halohydrins with aromatic sulphonamides to give compounds of the N-di(#-hydroxyethyl) - arylsulphonamide type, which yield a morpholine and an arylsulphonic acid when treated with sulphuric acid. Arylsulphonylmorpholines may be isolated as intermediate products which also give morpholines and arylsulphonic acids on scission with sulphuric acid. According to examples, toluenep-sulphonamide is condensed with ethylene chlorohydrin to form N - di(# - hydroxyethyl) toluene-p-sulphonamide, from which morpholine and toluene p-sulphonic acid are obtained. Some monohydroxyethyl - toluene - p - - sulphonamide is formed as an intermediate product. When propylene-a-chlorohydrin and # - chlor-#-phenyl-alphahydroxy-propionic acid are used, 2 : 6-dimethylmorpholine and 3 :5-diphenylmorpholine-2 : 6-dicarboxylic acid respectively are obtained. Toluenep-sulphonylmorpholine is prepared from N-di (#-hydroxyethyl)-p-toluene-sulphonamide by heating with sulphuric acid. #-chlor-#-phenyl-alpha-oxypropionic acid is obtained from glycidic acid and hydrogen chloride.

Title: Improvements relating to porous masses
IPC: B01D71/24
Filed: 1934-08-09
Abstract: Diaphragms of chlorinated rubber, which has been found to be microporous, may be employed in the separation of gas and liquid mixtures by diffusion or osmosis.  Such diaphragms, when impregnated with metals, e.g. palladium, platinum, copper, may be used as catalysts in the formation of hydrogen compounds, e.g. formic acid, ammonia or hydrogen peroxide.ALSO:Chlorinated rubber, which has been found to be of microporous structure, is used as a microporous film or diaphragm acting as a filter, diffusion membrane, ultra - filter or diffusion membrane. The porosity of the film may be varied (a) by stretching during or after the evaporation of the solvent, (b) by adding non-volatile p  substances such as resin, glycerine-phthalic acid, or condensation products to the solutions or emulsions to be worked up, (c) by altering the normal rate of evaporation of the solvent from the chlorinated rubber, e.g. by varying the pressure under which the evaporation takes place, or (d) by adding salt solutions to the material to be worked up, the salt being dissolved out after the film has been formed.  The films used may be formed by evaporating solutions of chlorinated rubber, or by running such solutions into a precipitating bath, or from emulsions of chlorinated rubber. Such films may be used as coatings on the dollies of dry cells to replace the usual fabric casing and films thickened by repeated super-position of layers or by deposition on a support, e.g. asbestos cloth may be used as diaphragms in electrolysis. Electrodes may be obtained by impregnating the microporous sheet with suitable metals, and such electrodes may be used to cause combination of electrolytically evolved gases, e.g. hydrogen in the nascent state or catalytically, as in the formation of formic acid, ammonia or hydrogen peroxide.  Microporous diaphragms of chlorinated rubber may be employed in electro-osmosis, or for the separation of gas or liquid mixtures by diffusion or osmosis, or as ultrafilters, or as a distributer when forcing gas into liquid. Fabrics coated or proofed with films of microporous chlorinated rubber may be used as or in raincoats, footwear, bandage linen, or sticking plaster.

Title: Apparatus for sealing or closing milk bottles
IPC: B67B1/10
Filed: 1925-09-19
Abstract: 259,018. Freeth, W. P., and Dairy Outfit Co., Ltd. Sept. 19, 1925. Stoppering.-In sealing milk bottles by means of cardboard &c. discs the movement of the bottle effects mechanically the removal of a disc from a vertical stack and its transference to a position over the sealing orifice which receives the bottle mouth, relative movement between a presser disc and the bottle then forcing the disc on to its seating. From a base 3, Fig. 1, supporting a vertical holder 1 for the disc 2, depends a bracket 4 to which is pivoted a rocking member 5 urged by gravity to protrude into the path of the bottle 18, its movement being limited by a pin 6 on the bracket 4 engaging in a slot 7 in the rocker 5. Upward movement of the bottle, as guided by a member 19 depending from the base 3, turns the rocker 5 and brings a cam 8 on its inner face into contact with the shorter arm 9 of a two-armed lever, the other arm 10 of which is adapted to move to and fro beneath the holder 1. Further movement of the rocker 5 turns the arm 9 and causes the arm 10, which has a circular recess at its outer end, to flick a disc from the holder 1 to a position above the bottle determined by a guard or stop 20. The rocker 5 then engages one arm 12 of a bell crank lever, the other arm 13 of which is adjustably connected to the stem 14 of a spring-pressed presser-disc 15 adapted to force the disc into the bottle mouth. In a modification, the upward movement of the bottle applies the disc and the downward movement feeds a fresh disc from the holder to the sealing orifice. In this form. the presser-disc 15, Fig. 5, is fixed and the bottle is received by member 25 slidable vertically in the base 3 and provided with a circular recess 26 for the disc 2. A guard, not shown, on the member 25 positions the disc in the recess. In the position shown, the flicker arm 10 is beyond the holder 1, but as the bottle descends, the rocker 5 moves to the right, a. slotted arm 23 on it engaging the short arm 9 of the flicker which transfers a disc from the holder 1 to the recess 26.
