Title: Improvements in and relating to acoustic apparatus
IPC: H04R7/18
Filed: 1932-05-21
Abstract: 399,598. Loud-speakers. MIDGLEY, A. H., c/o Midgley Leighton, Ltd., Wembley Hill Estate, Wembley, Middlesex. May 21, 1932, No. 14509. Addition to 332,272, [Class 40 (iv), Telephones &c.]. [Class 40 (iv).] Relates to an acoustic device, such as a moving coil loud-speaker or microphone, in which the diaphragm is loaded at its periphery by inertia rings orlike loading means and consists in providing damping means between the diaphragm and the loading means. The Figure shows a construction of device similar to that described in the parent Specification and comprising a diaphragm b having inertia rings d positioned peripherally round and on each side thereof, the rings being freely mounted on pins c extending from a back-plate or spider a carrying the magnet system. Cork &c. damping rings i are inserted between the diaphragm and rings d and felt washers o may also be provided on the outer faces of the rings. The coil e is secured to the diaphragm in a position slightly away from its centre, e.g. the coil is displaced from central by 25 per cent of the radius of the diaphragm. The radiation efficiency of the device may be increased by partially shielding the front of the diaphragm by a plate k having an aperture concentric with the coil of area approximately equal to one half the area of the diaphragm. This plate is spaced well away from the diaphragm so that it has substantially no damping effect thereon and the aperture in the plate may form the neck of an exponential horn l which may be surrounded by a baffle m.

Title: Process for the determination of particle size distribution
Inventor: MURLEY RICHARD DUNCAN
IPC: G01N15/04
Filed: 1966-04-07
Abstract: In order to determine particle size distribution so as to control the manufacture of finely divided particles of a predetermined size, a volume of a liquid suspension of the particles is rotated in a confined space around a central orifice at such a speed that particles of different sizes separate in the liquid, the surface of the liquid adjacent the orifice being covered to reduce evaporation therefrom, whereafter the weight of particles in a predetermined volume of the suspension is ascertained.  The process is repeated for different volumes of suspension, and the weight of particles in each volume of liquid examined is plotted on a graph from which the particle size distribution may be derived.  The particles may be solid, e.g. pigmentary titanium dioxide particles, or liquid, such as are present in a liquid emulsion.  The confined space may be constituted by a cylindrical cavity in a hollow vertically rotated disc provided with an orifice in its front face.  In order to observe the movement of particles in the liquid, at least the front face of the disc may be made of transparent material, e.g., Perspex (Trade Mark) or glass.  The suspension is introduced through the orifice into the cavity while the disc is rotated and a desired volume may be withdrawn up to a predetermined radius from the cavity, e.g., by means of a fine bore bent tube connected to a suction and collection apparatus.  Alternatively, the volume of suspension may be scanned in situ with an X-ray beam.  Covering of the surface of the suspension in the cavity to reduce evaporation may be by means of a liquid of higher boiling point and lower density than that of the liquid of the suspension, e.g. liquid paraffin, when an aqueous suspension of TiO2 is treated.
